A climate for change in Africa

A climate for change in Africa
by Calestous Juma from Climate Change Blog

Sub-Saharan African countries are bracing for dramatic impacts of climate change. As Andrew Simms of the UK-based New Economics Foundation has aptly put it, they are “caught between the devil of drought and the deep blue sea of floods.”

Africa’s greenhouse gas emissions have been minimal because of its low levels of industrial output. Yet African countries are likely to suffer disproportionately from global warming. They are therefore right to demand that international climate negotiations be based on principles of historical justice.

But behind this seemingly dismal outlook lies a unique opportunity for Africa to lead the way in adopting low-carbon growth strategies. The region is not too heavily committed to the same damaging industries that its industrial counterparts are having difficulties abandoning. African countries therefore need to complete their demand for historical justice with the design of climate-smart policies.

They can build climate-smart economies that take advantage of the vast amounts scientific and technological knowledge that is currently available. It is estimated that growth in such knowledge is doubling every 14 months.

Building climate-smart economies will involve taking deliberate steps in at least four key areas: infrastructure; technical education; business development; and international diplomacy.
Climate-smart infrastructure is essential for adapting to climate change. Take energy, for example. Eastern Africa can generate over 2,500 MW of electricity from geothermal energy using existing technologies, compared to the current world output of 8,100 MW.
Similar adjustments will need to be made in agriculture. Conventional crops will need to be complemented by switching to more resilient food sources such as tree crops. Breadfruit (Artocarpus alitis) which has for centuries been a staple in isolated Pacific islands is a prime candidate for adoption in diverse African regions.

Creating climate-smart infrastructure will require greater investment in higher technical training. Countries can build on current efforts to create telecommunications universities under line ministries, as has been done in Egypt, Ghana and Kenya. Ministries dealing with issues such as agriculture, environment, water, energy and transportation could play key roles in training local experts in the design of climate-smart infrastructure.

A bad climate for development

Poor countries’ economic development will contribute to climate change. But they are already its greatest victims

IN LATE April Mostafa Rokonuzzaman, a farmer in south-western Bangladesh, gave an impassioned speech at a public meeting in his village, complaining that climate change, freakish hot spells and failed rains were ruining his vegetables. He didn’t know the half of it. A month later Mr Rokonuzzaman was chest-deep in a flood that had swept away his house, farm and even the village where the meeting took place. Cyclone Aila (its effects pictured above) which caused the storm surge that breached the village’s flood barriers, was itself a plausible example of how climate change is wreaking devastation in poor countries.

Most people in the West know that the poor world contributes to climate change, though the scale of its contribution still comes as a surprise. Poor and middle-income countries already account for just over half of total carbon emissions (see chart 1); Brazil produces more CO2 per head than Germany. The lifetime emissions from these countries’ planned power stations would match the world’s entire industrial pollution since 1850.

Climate change spurs African concern over human rights
Global warming has reached a level that requires new legal instruments to protect refugees, according to the organization of West African States.
Morten Andersen 17/09/2009 20:40

The Economic Community of West African States (ECOWAS) sees a need for ”drafting a new legal instrument aimed at protecting people displaced by the effects of climate change and who are now outside their country of origin,” according to a declaration from an ECOWAS conference held in the Togolese capital Lome.

The declaration further calls for the ”establishment of a special fund on the impact of climate change on the affected populations” and for the concern by the Western African states over human rights issues in relation to climate change to be included ”in the formulation of a common African position during the Copenhagen talks.”
A joint position of the West African nations on the overall issues for the UN conference in the Danish capital this December will be discussed during a conference of the African Union in Addis Ababa by late October.

Africa Climate Change Threatens Life and Health of Maasai Women

Africa Climate Change Threatens Life and Health of Maasai Women

Kajiado, Kenya: The Maasai are struggling with frequent water shortages which are threatening their way of life. But one women’s group is taking action.

Day in and day out from the months of March through to June, grey and white clouds float across the blue skies above Kajiado, southern Kenya. But each passing day, the rain they promise frequently fails to show up.

“There’s been practically no rain in the region,” says David Kirrinkai, the assistant chief of Oliteyani, a sub-location of Ngong Hills in Kajiado. “We just receive a few showers, with no means of tapping it for storage.”

The lack of rain has had serious implications for the environmental region as both people and animals are suffering. The Maasai people have to share the land with all kinds of wildlife here. And when water is short in supply, incidents of conflict arise.

The Maasai have lived and coped here for centuries, but the new weather patterns are threatening their way of life. In recent decades, seasonal patterns have become unpredictable and rainfall levels have become lower.

As traditional cattle herders, the Maasai have found themselves leaving their homes for months at a time in search of pastures and water for their animals. In most cases this means vulnerable women, children and the elderly are left behind to fend for themselves in the villages.

Maasai herders dressed in their bright red shuka cloaks, have now become a common feature on the outskirts of the capital, Nairobi, as they search for pastures. Others are dropping out of their pastoral lifestyle altogether and moving to the cities in search of employment.
“The devastation can be too much to bear,” says James Lekurra, a Maasai elder who lost his entire herd to the drought. “Three decades ago, the rains used to come regularly and we had little stress. But now the atmosphere has changed. We are no longer sure that the rains will come as we expect.”

The recurrence of droughts in East Africa is a natural calamity that is delivering a serious blow to the region. Scientists blame the massive clearance of forests as well as the emission of carbon gasses into the atmosphere as a cause of the droughts.
Women in particular face the challenge of fetching the scarce water for the household’s use. In some cases they are forced to walk for over ten kilometers in search of water. When droughts worsen and springs dry up, some are forced to return home empty-handed.

AFRICA: Trees "vital for food security"

AFRICA: Trees "vital for food security"

NAIROBI, 28 August 2009 (IRIN) - Countries tackling food insecurity and climate change adaptation can greatly benefit from agroforestry - integrating fleshy plants and trees into their farming systems, environmental specialists say.

Sub-Saharan Africa has a history of food insecurity brought on by meagre rains, land degradation, declining soil fertility and bad management of resources, among other factors. "How do we, in a world of more than six billion people, rising to perhaps over nine billion, feed everyone while simultaneously securing the ecosystem services such as forests and wetlands that underpin agriculture, and indeed life itself in the first place?" Achim Steiner, Executive Director of the UN Environmental Programme (UNEP), posited at the second World Congress on Agroforestry in Nairobi. "We can empower people - not to wait for others to do something for them – but to take the initiative, one tree at a time," Steiner said.

"Trees are one of nature’s most ingenious answers to many of our problems." Agroforestry helps supply fodder, fruit and nuts as well as trees and shrubs that produce gums, resins and valuable medicines. Steiner said agroforestry may have many roles to play in the new landscape of rewarding countries for their natural or nature-based services.

"Firstly it offers the potential for maximizing sustainable food production in the zones surrounding natural forests while also boosting biodiversity and other ‘natural infrastructure’. "Secondly, it offers an opportunity for timber production and thus alternative livelihoods to meet perhaps a supply gap that may emerge under a fully-fledged REDD [Reduced Emissions from Deforestation and forest Degradation] regime. "Thirdly these agroforestry areas can also potentially secure flows from carbon finance in their own right."

Better REDD REDD is a strategy to help local communities conserve forests, including funding these efforts through governments and market-based mechanisms, such as trading the carbon stored by forests as credits to greenhouse gas-emitting industries. Trees such as the Faidherbia albida, a leguminous acacia-like tree, are especially useful.

“Faidherbia goes dormant at the beginning of the rains and deposits abundant quantities of organic fertilizer on to the food crops to provide nutrients and increase yields, totally free of charge," said Dennis Garrity, World Agroforestry Centre (ICRAF) Director-General. "They are fertilizer factories in the food crop fields." The leaves and pods of the Faidherbia, which are adapted to a wide array of climates and soils from deserts to humid tropics, provide fodder in the dry season too.

Garrity said: "The much higher food prices... have exacerbated the pain of hunger in hundreds of millions of households. The standard solutions just aren’t working. The question is, what are we as agroforestry scientists going to do about it? What are we going to contribute to sustainable solutions?" With shrinking forests, he said, "the rising demand for tree products will have to be met from farm-grown sources. Clearly, agroforestry science has much to offer in overcoming the food security challenges in Africa, and elsewhere in the world.

" Tree cover According to a 24 August report by ICRAF, "tree cover is a common feature on agricultural land", and represents over one billion hectares of land. "Agroforestry, if defined by tree cover of greater than 10 percent on agricultural land, is widespread, found on 46 percent of all agricultural land area globally, and affecting 30 percent of rural populations," stated the report. Namanga Ngongi, president of the Alliance for a Green Revolution in Africa (AGRA), said: "Seventy-five percent of Africa’s farm lands are degraded, and deforestation is taking place at four times the global average, destroying 1 percent of our forests every year." Agroforestry alone could remove 50 billion tonnes of carbon dioxide from the atmosphere over the next 50 years, meeting about a third of the world’s total carbon reduction challenge, according to ICRAF studies.

Carbon payback Nobel Laureate Wangari Maathai suggested that subsistence farmers might be more willing to invest in farming trees if there were carbon credit revenue guarantees. UNEP recently launched a Carbon Benefits Project in the catchments of Lake Victoria, Niger, Nigeria and China, which seeks to find a standardized way of assessing how much carbon is actually locked away in vegetation and in soils under different land-management regimes. This has been a major challenge for African smallholders seeking to access the carbon market.

Preliminary findings are expected within 18 months. According to Steiner, economic incentives are required to reverse deforestation and forest degradation. "...Simply locking away forests to secure their carbon as if they are the Queen’s jewels, or putting up the modern equivalent of a Berlin Wall between forests and people, is almost certainly folly and almost certainly a recipe for disaster," he said. aw/js/am/mw

UN says Climate Change Hurting African Women

By Ricci Shryock Dakar17 September 2009

A U.N. official has told a regional conference in Togo that climate change in West Africa is disproportionally affecting women and girls.Human rights workers and senior government officials converged to discuss climate change this week in Togo. U.N. Development Fund for Women Regional Director Cecile Mukarubuga asked the 89 participants to consider the extraordinary challenges women are facing."The negative impact of climate change effects the agriculture and food production, and we all know that in Africa women contribute to 80 percent of the food production," said Mukarubuga.

"When they are hit by climate change negative impact, they lose all their livelihood means, and they lose their source of income. And we also know because they are not owners of the land and the access to land is difficult for them, they are not coping easily after a disaster."Mukarubuga says climate change is affecting drop out rates among young girls who quit school to help their struggling mothers.

"The responsibility of collecting water and firewood is women and girls' responsibility," she said. "With the negative impact of climate change, girls and women are spending more time walking longer and longer distances to collect water and firewood, and this has an impact on the time that should be dedicated to activities, like economic activities and education.

"U.N. spokesperson Michel Olabiré da Cruz says the focus of the conference was to gather ideas from 15 West African nations before the global climate conference this December in Copenhagen.

"The objective of the regional conference is to have a position, one position, for the West African countries at the Copenhagen meeting that will be held in December," said Olabiré da Cruz One concrete issue has been agreed on. African countries say they want industrialized nations to limit global warming to two degrees Celsius and cut emissions from 25 - 40 percent by 2020.

The Africa-wide Civil Society Climate Change Initiative for Policy Dialogues (ACCID)

Background

The current global climate crisis has led to the creation of a global market for developing country emission credits. In 2007, the World Bank valued these emission credits at over US$7.5 billion. This carbon market allows projects that reduce Green House Gas (GHG) emissions to sell their credits to companies and governments in industrialized countries that have committed to cut their GHG emissions.

The income from selling the credits could help beneficiary countries to invest behind climate-friendly and sustainable development. The Kyoto Protocol and the resulting carbon markets have a narrow focus on industrial and energy-related emissions which only benefits a few African countries with a sizeable industrial base such as Nigeria, South Africa and Egypt. As a result of this biased focus, out of more than 1,100 Clean Development Mechanism (CDM) projects registered by June 2008, only 17 are located in Africa, and of those 17, Uganda, Tanzania and Nigeria have one project each, whilst the remaining 14 are located in South Africa.

The issue

In Sub-Saharan Africa, agriculture, forestry, and land use (commonly referred to as AFOLU) holds the most promising potential for carbon finance. Presently the carbon market is driven by buyers’ preferences and has shown little interest in supporting genuine poverty eradication and sustainable development in Africa’s largely agro-based economies. Notably, the less industrialized African countries already store significant amounts of carbon in their soils and forests. It is the conviction of COMESA, SADC and EAC regional blocs that these countries should be recognized and rewarded for contributing to addressing climate change through sustainable agriculture, forest management, and other environmental conservation practices.

The November 2008 Nairobi Declaration on Climate Change adopted by the COMESA Ministers of Agriculture and Environment advocates for the inclusion of all bio-carbons in the post 2012 climate change regime. It also notes that the continent cannot afford to wait any longer, and demands that the rules for a post-Kyoto agreement must change. AFRICA is PRO-REDD and PRO-AFOLU.

Civil Society in Support of African Governments COMESA, in conjunction with SADC and EAC, mandated FANRPAN to mobilise African civil society organisations (CSOs) under the Africa-wide Civil Society Climate Change Initiative for Policy Dialogues (ACCID) and facilitate dialogue around the Africa Bio-Carbon proposal. The main objective of these dialogues is to ensure alignment between African governments and CSOs with regards Africa’s approach to tackling the current Climate Change negotiations and beyond. AFRICA is advocating for a post 2012 protocol that is PRO-REDD and PRO-AFOLU.

Medicinal Plants and Traditional Medicine in Africa

Medicinal Plants and Traditional Medicine in Africa

TRADITIONAL MEDICINE DEVELOPMENT FOR MEDICAL AND DENTAL PRIMARY HEALTH CARE DELIVERY SYSTEM IN AFRICA.

Abstract
Traditional African Medicine (TAM) is our socio-economic and socio-cultural heritage, servicing over 80% of the populations in Africa. Although, it has come a long way from the times of our ancestors, not much significant progress on its development and utilization had taken place due to colonial suppression on one hand, foreign religions in particular, absolute lack of patriotism and political will of our Governments, and then on the other hand, the carefree attitudes of most African medical scientists of all categories. It is incontrovertible that TAM exhibits far more merits than demerits and its values can be exploited provided the Africans themselves can approach it with an open mind and scientific mentality. The degree of sensitization and mobilization by the World Health Organization (WHO) has encouraged some African countries to commence serious development on TAM. The African Regional Director of the WHO has outlined a few guidelines on the responsibilities of all African nations for the realistic development of TAM, in order to sustain our health agenda and perpetuate our culture. The gradual extinction of the forests and the inevitable disappearance of the aged Traditional Medical Practitioner should pose an impending deadline for us to learn, acquire and document our medical cultural endowment for the benefit of all Africans and indeed the entire mankind.

Introduction
Traditional Medicine, as a major African socio-cultural heritage, obviously in existence for several hundreds of years, was once believed to be primitive and wrongly challenged with animosity, especially by foreign religions, dating back to the colonial days in Africa and subsequently by the conventional or orthodox medical practitioners. However today, Traditional Medicine has been brought into focus for meeting the goals 47
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
of a wider coverage of primary health care delivery, not only in Africa but also, to various extents, in all countries of the world. Traditional Medicine is the first-choice healthcare treatment for at least 80% of Africans who suffer from high fever and other common ailments.
Primary Health Care (PHC) is the key to the development of a national health policy and as defined by the Alma-Ata Declaration of 1978, it is an essential health care, based on practical, scientifically sound and socially acceptable methods and technology made universally acceptable to individuals and families in the community and through their full participation and at a cost that the community and the country can afford, in oder to maintain, at every stage of their development, in the spirit of self-reliance and self determination. It is the first level of contact for the individual, family and the community within the national health care system, bringing health care as close as possible to where people live and work and thus constitutes the first element of a continuing health care process (WHO, 1978a). A health system, based on primary health care was adopted as the means of achieving the goal of health for all by the year 2000. Most developing countries of the world, for which the scheme was designed, have failed to seriously implement it up till this moment (in the year 2004). Hence the goal of “health for all” remains unattained in all such countries.
Examining the philosophy from the critical view point of the definition of Primary Health Care, it is easy to assess the orthodox practice alongside the traditional type of health care in the African context. Specifically in the areas of social acceptability, cost affordability, self-reliance, cultural compatibility, relevance and community participation, the orthodox or the modern/western-based medicine and dentistry have not been adequate for the majority of African populations and that if we must make progress, there is an inevitable need for the official integration of traditional medicine and the utilization of traditional medical practitioners into the PHC system in Africa. The only health care providers close to them are the traditional medical practitioners, living with them and providing healthcare services in the same communities. The western type of health institutions are out of the reach of most people in terms of distance and costs, especially at the village setting. On the other hand, the orthodox medicine, as currently made available today in Nigeria (as in most African countries), so long as every nook and corner of our rural populations in Africa cannot yet be provided with basic health care needs including full-time resident medical personnel and readily available and affordable drugs, the practice of conventional medicine has failed us woefully. Although wherever, modern health facilities exist, traditional medicine is incomparable. Therefore, the most workable health agenda for Africa is the institutionalization of traditional medicine in parallel (not in complete fusion) with orthodox medicine, within the national health care scheme in order to move the health agenda forward. Effective health agenda for the African continent can never be achieved by orthodox medicine alone unless it is complemented by traditional medicine practice.
Traditional Medicine is defined by the World Health Organisation (WHO, 1978a) as the sum total of knowledge or practices whether explicable or inexplicable, used in diagnosing, preventing or eliminating a physical, mental or social disease 48
Afr. J. Trad. CAM (2005) 2(1): 46- 61
which may rely exclusively on past experience or observations handed down from generation to generation, verbally or in writing. It also comprises therapeutic practices that have been in existence often for hundreds of years before the development of modern scientific medicine and are still in use today without any documented evidence of adverse effects.
The explicable form of Traditional Medicine can be described as the simplified, scientific and the direct application of plant, animal or mineral materials for healing purposes and which can be investigated, rationalized and explained scientifically. The use of Salix alba, the willow plant (containing the salicylates) for fever and pains which led to the discovery of aspirin, would belong to this form of Traditional Medicine. Herbal medicines, which squarely belong to this form, are regarded by the World Health Organisation, as finished and labeled medicinal products that contain, as active ingredients, aerial or underground parts of identified and proven plant materials, or combination thereof, whether in crude form or as plant preparations. They also include plant juices, gums, fatty oils, essential oils etc (WHO, 1978a). There are several other official modern drugs today, which were originally developed like aspirin through traditional medicine e.g. morphine, digoxin, quinine, ergometrine, reserpine, atropine, etc and all of which are currently being used by orthodox medicine in modern hospitals all over the world. The inexplicable form of Traditional Medicine on the other hand, is the spiritual, supernatural, magical, occultic, mystical, or metaphysical form that cannot be easily investigated, rationalized or explained scientifically e.g. the use of incantations for healing purposes or oracular consultation in diagnosis and treatment of
diseases. The explanation is beyond the ordinary scientific human intelligence or intellectual comprehension.
The traditional medical practitioner (TMP) or Traditional Healer (TH) is described as a person who is recognized by the community in which he lives as competent to provide health care by using vegetable, animal and mineral substances and certain other methods (WHO, 1978b); serving as the nurse, pharmacist, physician, dentist, mid-wife, dispenser etc. The specialists include herbalists, bone setters, traditional psychiatrists, traditional pediatricians, traditional birth attendants (TBA), occult practitioners, herb sellers, general practitioners, etc; they are certainly more readily available, accessible and approachable than the orthodox physicians while their services are much more affordable than modern medical facilities. No doubt, the traditional healers, diagnosing and managing various common diseases at PHC level, with various herbal dosage forms namely, concoctions, decoctions, infusions, dried powders, ointments, tinctures and macerates, are much closer to the community than the orthodox doctors who are mainly found in urban healthcare locations. The TMPs administer these medications through various routes such as oral, rectal, intra-uterine, sub-cutaneous, external or topical applications. Although most Governments in Africa are yet to pass into law, the official recognition of their practices (like in China, Japan, India, Thailand and Korea), the practitioners have been generally acknowledged excellent at PHC level in the areas of bone setting, psychotherapy in psychiatry, hydrotherapy as well as obstetrics and gynaecology (by the TBA). Whether approved or not by the Governments, Traditional Medicine continues to play a very significant role in the medical and dental primary health care implementation in Africa and other developing countries of the world, most especially in the rural areas which cover almost 80% of the entire population. 49
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
The World Health Organisation has since urged developing countries of the world to utilize the resources of Traditional Medicine for achieving the goals of Primary Health Care. This injunction stems round the various advantages of Traditional Medicine namely, low-cost, affordability, ready availability, accessibility and acceptability and perhaps low toxicity. The practitioners are ready sources of medical and dental manpower. It is also expected that in recognizing them and hence utilizing the advantages, the various disadvantages of the practice can also be resolved. These include lack of adequate scientific proof, imprecise diagnosis and dosage, unstandardized medicines and occultic practices.
Trends in drug discovery from indigenous medicine
Plants, which have formed the basis of sophisticated traditional medicine systems for thousands of years, were originally instrumental to early pharmaceutical drug discovery and industry. Hence, the history of drug discovery and even drug chemistry is inexorably bound to the plant kingdom and the process of deriving drugs from plant sources is certainly not new (Parfitt, 1978).
(a) Evidence outside Africa

In 1785, the English Physician, discovered the medicinal uses of Foxglove (Digitalis purpurea) which gave rise to digoxin, an indispensable cardiac drug; while
Ergot of Rye (Claviceps purpurea) was discovered as the foremost natural uterine stimulant while the analgesic morphine was produced from opium poppy flower (Papaver somniferum) by a French scientist; strychnine from Strychnox nuxvomica was isolated as a CNS stimulant in the 19th century; quinine for malaria fever from Cinchona officinalis was reported during the same century. Ephedrine (from Ephedra sinica) was discovered for asthma from the Traditional Chinese Medicine in the 20th century. The first British Pharmacopoeia of 1863 contained descriptions of 187 crude drugs including Digitalis, Datura, Belladona and Hyoscyamus. There is therefore little or no doubt that ethnographic (ethnopharmacognosy) research can provide important clues leading to new drugs for the modern Pharmacies. It is the herbal medicine (among other alternative therapies available in the U.K.) that has seen the biggest interest in recent years. About 85% of Japanese doctors prescribe herbal medicines (KAMPO) and two-thirds of the Indian populations use Ayurvedic medicines. There has been about 26-fold increase in the budgetary allocation (USD 52 million) for Complimentary and Alternative Therapies by the US Congress within 1992 to 1998 and this was doubled (USD 104 million) in 2002 (Enwonwu, 2003). Curricula of some 80 US medical schools had included some topics in Complimentary and Alternative Medicine. Over 75% population in France had used complimentary and Alternative Medicine at least once, while about 77% of the pain clinics in Germany provide acupuncture as official therapy. In the USA, over 1,500 herbal drugs (approximately worth of billion US dollars) were sold annually and in the United Kingdom, the annual expenditure on Complimentary and Alternative Medicine was 2.3 billion US dollars. Over USD 2.4 billion Traditional Chinese Medicines (TCM) were sold and USD 400 million worth of 50
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
TCM were exported out of China in 1993; about USD 60 million was realized from herbs in 1996 in Malaysia and in Europe, North America and Africa, about 75% of people living with HIV/AIDS patronize Complimentary and Alternative Medicine. As a whole, the annual market value of herbal drug products is close to USD 43 billion which is more than the total annual budget of many Africa countries (Enwonwu, 2003).
(b) Evidence within Africa
(I) Current Supports from Some Relevant Organizations

On the other hand, the orthodox medicine, as currently made available today in Nigeria (as in most African countries), so long as every nook and corner of our rural populations in Africa cannot yet be provided with basic health care needs including full-time resident medical personnel, the practice of conventional medicine has failed woefully. Although wherever, modern health facilities exist, traditional medicine is incomparable. Therefore, the most workable health agenda for Nigeria is the institutionalization of traditional medicine in parallel (not in complete fusion) with orthodox medicine, within the national health scheme in order to move the health agenda forward. Effective health agenda for Nigeria can 51
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
never be achieved by orthodox medicine alone unless it is complemented by traditional medicine practice. 52
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
The Relevance of the World Health Organisation (W. H.O)
The World Health Organization, has for several decades, supported, promoted and assisted the development of traditional medicine in the bid to move the African health agenda forward, particularly for the less-developed countries of the world. This philosophy was reinforced at the Alma Ata declaration of 1978 when it became obvious
that the large majority of the developing countries of the world were unable to provide health care to the populations using the imported orthodox health facilities. Since then, the W.H.O, utilizing several expert committees’ policy decisions and resolutions, etc. had provided adequate guidelines that countries could use to develop and utilize their indigenous systems of medicine, for their individual national health agenda.
The Regional Office in Brazzaville, responsible for the specific needs of the African Region in this regard has since carried out several activities toward the promotion of traditional medicine. The current trend in the recognition and development of Herbal Medicine in Africa by various international organizations calls for positive response from all the medical and pharmaceutical research scientists of African origin. Firstly, the African Heads of States have since declared the next ten (10) years (2001-2010) as a period for Traditional Medicine development in Africa and this has been tagged as the “Decade of Traditional Medicine in Africa”. Hence the 31st of August every year is to be observed and celebrated as the African Traditional Medicine Day in all the countries of the Continent. The maiden celebration of African 53
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
Traditional Medicine Day was marked in August 2003 with the theme: “Traditional Medicine – Our Culture and Our Future”.
The second African Traditional Medicine Day came up on 31st August 2004 and with the new theme: “Moving African Health Agenda Forward with Traditional Medicine” and with the following messages from Dr. Ebrahim Maluc Samba, the WHO African Regional Director, on the occasion of the second African Traditional Medicine Day, celebrated on 31st August 2004:
“Today 31 August 2004, Africa commemorates the Second African Traditional Medicine Day. The theme for this year’s commemoration is “Moving African Health Agenda Forward with Traditional Medicine”. This is a very important event which should be accorded due recognition, support and commemoration by all the stakeholders engaged in the development of African Traditional Medicine.
“The main message in the theme”
What does the theme, “Moving African Health Agenda Forward with Traditional Medicine” mean? The theme befits the occasion because Africa has, over the centuries, moved the health agenda forward with traditional medicine in that it has been with us before the advent of conventional medicine. African people have used traditional medicine to combat disease affecting the health of their families since time immemorial. It was the only form of medicine used for the prevention, diagnosis and treatment of social, mental and physical illnesses. It is acceptable, accessible and affordable by the majority of African people. Today, more than 80% of the population living in Africa use traditional medicine. For most, it is the only source of hope for the management or treatment of some priority diseases such as HIV/AIDS and sickle cell anaemia. Even though traditional medicine was often denigrated as backward practice
during the colonial era, it has continued to thrive because it is culturally accepted by the African population. For some communities, it is the only system available because western medicine is too costly and sometimes unavailable. While the World Health Organization recognizes and respects traditional medicine, it also has a responsibility to ensure that quality, safe, effective and affordable traditional medicines are produced in Africa for Africans and the world. Because of this, WHO has developed various guidelines for the development and delivery of quality traditional medicine services.
“Contributions of traditional medicine to health in Africa”
Traditional Medicine has demonstrated its contribution to the reduction of excessive mortality, morbidity and disability due to diseases such as HIV/AIDS, malaria, tuberculosis, sickle-cell anaemia, diabetes and mental disorders. Traditional Medicine reduces poverty by increasing the economic well-being of communities and developes health systems by increasing the health coverage to the people.
“What is required by African countries under the theme”?
The major challenge is that scientifically-based evidence on Traditional Medicine, quality standards and regulations are not being developed at the same pace 54
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
as the demands for the medicines. Therefore, Member States of the WHO African Region need to scale up institutionalization of African Traditional Medicine in their health systems. Institutionalizing African Traditional Medicine in health systems is a key pillar in the promotion and development of Traditional Medicine in this 21st century.
“Steps to be taken by individual countries in compliance”
W.H.O has developed model tools for institutionalizing African Traditional Medicine in health systems. The models are available to those who need them and may be adopted or adapted for local situations. Government can undertake the following actions in order to move the health agenda forward with Traditional Medicine, namely:
a. Develop policy, legal and regulatory frameworks for the practice of traditional medicine within the framework of national health policies and health legislation;
b. Promote and conduct relevant scientific research on medicinal plants in collaboration with traditional health practitioners to validate claims made on safety, efficacy and quality of traditional medicines.
c. Ensure that intellectual property rights are priority items on the agenda of Member States to protect indigenous knowledge about Traditional Medicine;
d. Establish an enabling economic, regulatory and political environments for local production of traditional medicines as well as develop industries that can produce standardized remedies to increase access;
e. Register traditional medicines, if need be, by using the W.H.O Guidelines on Registration and regulation of Traditional Medicines in the W.H.O African Region;
f. Disseminate appropriate information to the general public to empower them with knowledge and skills for the proper use of traditional medicines;
g. Build human and material resource capacity in order to carry out and accomplish institutionalization strategies.”

Secondly, the African Regional Director of the World Health Organization (WHO) has placed a big challenge before the Regional Expert Committee on African Traditional
Medicine as well as the several WHO Collaborating Centers for Traditional Medicine in Africa, that within the next few years, at least a drug each must have reached the market in the following priority diseases in Africa: Malaria, HIV/AIDS, Sickle Cell Anaemia, Diabetes and Hypertension.
What is the current status of the integration of traditional medicine in national health systems of countries in the African Region?
Countries in the WHO African region are at different stages of integration of TM in health systems. Some of the key actions that are 55
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
recommended to Member States for integration of TM in health systems and services include the following:
i. Political recognition: This is already there as the African Summit of Heads of States and Governments have made various declarations including research on traditional medicines used for the treatment of priority diseases to be made a priority and the period 2001-2010 as the Decade of African Traditional Medicine.
ii. Formulation of policy, regulatory and legal frameworks: Some countries have formulated national policies, legal frameworks and regulations including mechanisms for registration of traditional medicinal products, established national expert committees, national programmes and national offices and developed training programmes for various cadres of health workers. WHO is supporting this process in Member States through the provision of guidance in these policy issues.
iii. Conducting research on traditional medicines: Countries are conducting research in order to validate claims made on quality, safety and efficacy of traditional medicine used for the management of priority diseases such as HIV/AIDS, malaria, sickle cell anaemia, diabetes and hypertension. WHO has developed guidelines on research methodologies and is supporting countries in this process.
iv. Collaboration and partnership arrangements: Countries such as Burkina Faso, Madagascar, Mali and Tanzania have made partnership arrangements with traditional health practitioners and the private sector as equal partners because trust among collaborators is crucial, and this holds the key to the success of integrating TM, WHO has developed memorandum of under- standing between biomedical researchers and traditional health practitioners which countries can adapt to their local situations.
How should this integration be carried out?
Integration or harmonization of African Traditional Medicine does not have to be in the fashion of the Chinese, Koreans or Vietnamese.
Member States need to find and develop systems of harmony between traditional and modern systems of health care in the African context, with the minimum threat to each other. Member States working jointly with all stakeholders have to develop systems that will ensure economic survival and social acceptance of both systems of health care coverage to the majority of the population. By doing so we will have Moved African Health Agenda forward with Traditional Medicine. 56
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
(II) Research focus on African Plants
Basic information as a lead to scientific probing of medicinal plants in Africa has been obtained from herbalists or traditional medical practitioners, native herb sellers and the local, indigenous people (Baba, et al., 1992). By the early nineties, screening work on African medicinal plants has advanced with publications arising from the following research areas: antimicrobial (16%), molluscicidal (11%), antimalarial (7%), plant toxicology (7%), antitumour-related studies (4%) and others (54%) (Sofowora, 1993a). For molluscicidal activity: Phytolacca dodecandra, Tetrapleura tetraptera (Table 1) and Swartzia madagascariensis had become an international research interest for the control of schistosomiasis (Adewunmi, 1991). Gedunin and nimbolide, two of the several limonoids in Azadirachta indica were pruned down as the antimalarial constituents (Khalid and Deddeck, 1989). The root of Cryptolepis sanguinolenta, used for treating urinary infections in Traditional Medicine is strongly antimicrobial with cryptolepine as the active principle. Its extract has been formulated by the Center for Research into Plant Medicine in Ghana. The common chewing sticks used by the Africans in various communities for traditional dental care have been reported to possess actions against oral microbial flora and to contain various minerals which can hinder plaque formation in Dentistry (Sofowora, 1993b). The most outstanding of the chewing sticks, Zanthoxylum zanthoxyloides (Lam.) Waterm. (Rutaceae), also an antisickling and anticancer plant, was found to contain alkaloids: berberine, fagaronine, chelerythrine, canthin-6-one and benzoic acid derivatives as the main active ingredients. Ancistrocladus abbreviatus (Ancistrocladaceae), a Cameroon plant species, showed a strong anti-HIV activity in the laboratory of the National Cancer Institute in the U.S.A. The antiviral component has been pinned down to Michelamine B., which was being developed for people living with HIV/AIDS.
(III) Local Drug Formulation and Production From African Plants
The need has since been expressed for industrial drug production from medicinal and aromatic plants in Africa in order to increase the economic and health potentials as well as the social benefits from our natural resources. To date, over 30% of the pharmaceutical products manufactured in Egypt are plant-derived e.g. Ammi visnaga, Glycyrrhiza glabra, Aloe vera etc. Rwanda and Zimbabwe also produce pharmaceuticals from plants’ essential oils. Dr. Fumba’s Center in Burundi provides and makes available both orthodox and traditional drugs for the hospital dispensaries.
In the Centre for Scientific Research into Plant Medicine established in Ghana since 1973, pilot drug production is carried out to provide well-formulated, stable,

standardized and safe preparations from plants for clinical evaluation, utilization and monitoring in a clinical setting. Similarly, in the Centre for Research on Pharmacopoeia and Traditional Medicine in Rwanda, Datura stramonium; Eucalyptus globules, Capsicum frutescens and Plantago lanceolata are prepared in the Dispensary of Traditional Medicine where they are administered for antispasmodic, pulmonary disinfectant, counter-irritant and anti-tussive activities, respectively. And also in Mali, several herbal products have been formulated as tea bags for use as follows: Dysenteral (Euphorbia hirta for dysentery), Laxa cassia (Cassia italica for constipation) and Hepatisane (Combretum micranthum for constipation). These drugs are now produced 57
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
by private herbal industries in Mali for clinical application. The “Village Chemist” outfit in the Department of Pharmacognosy of Obafemi Awolowo University, Ile-Ife, in Nigeria has embarked on herbal drug manufacture of many standardized and efficacious herbal preparations, basically for use in the management of different opportunistic infections in people living with HIV/AIDS (PLWHA) namely antithrush, (HAT DECOCTION), antifever (MAMA DECOCTION), antidiarrhoea and antidysentery (DIAFFIN JUICE/XYLOGIN POWDER), anticough (COFER INFUSION) and anti-infective against various skin pathogens (PAMET/PAMETONE/CAGELO SOAPS & ABAFICIN DECOCTION).
(IV) Plants as dental drugs
About 10 different oral/dental conditions treatable with plants are common in traditional health practice namely: toothache/decay, gingivitis, ulcerative gingivitis, angular stomatitis, mouth ulcers, swollen tonsil, oral thrush, tonsillitis and black tongue (Hollist, 2004). Most common plants in the field include Piper guineense, Xylopia aethiopica, Citrus aurantifolia and Aframomum melegueta. For ordinary oral hygiene and in many African homes, teeth are cleaned in the morning by chewing the roots or thin stems of certain plants until they acquire brush-like ends (El-Said et al, 1971). The fibrous end is used to brush and clean the teeth thoroughly every morning. In certain parts of West Africa e.g. Senegal, chewing sticks are used frequently during the day as well. Zanthoxylum zanthoxyloides (Lam.) Waterm. root imparts tingling and peppery taste sensations and numbness in the mouth; Masularia acuminata (G. Don) Bullock ex Hoyle stem, produces a strong bitter taste and frothing; an initial bitterness and later sweet taste by Vernonia amygdalina Del. root (Tella, 1976) while Terminalia glaucescens Planch. root gives a discolouration of the mouth after use (Sofowora, 1993b). The antimicrobial activities of the individual chewing sticks have been investigated, showing that all of them were active against the oral microbial flora in varying degrees. The antimicrobial action of Zanthoxylun zanthoxyloides is attributed to the presence of benzoic acid derivatives (Odebiyi and Sofowora, 1979). The phenolic acids were active at a pH of about 5 and the alkaloids (Canthin – 6 – one, berberine and chelerythrine ) were active at a pH of 7.5, meaning that the root contained antimicrobial compounds, active at both alkaline pH (during heavy tooth decay) as well as acid pH (after a drink of lime or grape juice). Odusanya, with others (1979) reported that some African chewing sticks possessed fluoride ions but at insufficient concentrations and also silicon, tannic acid, sodium bicarbonate as well as other natural plaque-inhibiting substances that could reduce bacterial colonization and plaque formation in the mouth (Akpata et al 1977). Tella (1976) reported antimicrobial properties of the crude root of Vernonia amygdalina in gingivitis and toothache. Bruneton (1995) and Kocry (1983) have elaborated on the use of chewing sticks in preventive oral hygiene while Ogunbodede (1991) documented the role of traditional healers in dental care.
(V) Toothache and Tooth Extraction Techniques with Medicinal Plants

The immature pericarp of Ganipa americana (Family Rubiaceae) is used for tooth extraction by placing the pulp onto the aching tooth, left in place for several weeks for 58
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
the disintegration of the tooth which is then removed in pieces, with little or no trauma (Lewis and Lewis, 1977). The stem-sap of Stigmaphyllon species (Family Malpighiaceae) is placed on the carious tooth for about 4 hours followed by other repeated applications throughout the day. After one week, the tooth can be removed without bleeding or pain. The aggressive stinging ants, found inside the stems of Triplans species (Family Polygonaceae) are crushed and placed on the aching tooth for one week. The tooth is then pulled out with the fingers. It is believed that the formic acid (among other substances) in the stinging ants is responsible for the activity. One application, followed by repeated contact, using cotton swab of the latex of Chlorophora tinctora (Family Moraceae), is also used for tooth extraction. No pain, trauma or bleeding is involved (Garcia, 1974; Maxwell, 1962). Careless applications resulting in spillage or damage to other teeth, adjacent to carious teeth, may lead to unintended extraction of unaffected teeth. The use of the juice of Ficus species (Moraceae) for toothache has revealed analgesic and anti-irritant properties. Other plant species recorded for tooth extraction include Conssapoa glaberima (Moraceae) and Asclepia curassavica (Asclepidaceae) and for toothache include Alchornia cordifolia, Curcuma domestica, Piper guineense and Syzigium aromaticum (Table 2).
(VI) Teeth Colouring
Teeth blackening with plants, sometimes up to one year, is done for the purpose of preserving the teeth, controlling dental caries and keeping the teeth strong and healthy. Some of the blackening plant species include: Neea parviflora (Family Nyctaginaceae), Manettia divaricata, Manetta glandulosa, and Duroia hirsute.
(VII) Clove bud in Dentistry

Eugenol, the main chemical constitutent of the volatile oil from Clove (Syzigium aromaticum) is eugenol, and has been used for a long time by Dentists through intracanal route; as a dressing in Dentistry, for treating minor oral wounds; as an analgesic in painful and infective diseases of the oral cavity and oropharynx as well as for general oral hygiene. In general medicine, clove is used as an agent against flatulence, stomach distension and gastro-intestinal spasm. Rapidly metabolized and excreted in conjugated forms, eugenol is not a carcinogen. Official formulation includes: Zinc Oxide and Eugenol (ZOE) paste, in form of lozenges, mouthwashes and neat clove oil. It is recognized as safe and may be added to foodstuffs in concentrations of up to 1,500ppm (i.e. 0.15%). The Indonesian cigarettes called “kretek” contains 40% clove. Side effects of eugenol include irritation of oral tissues and CNS depression (when used in systemic administration) which do not constitute serious health hazards to suggest withdrawal. The use of clove is unfortunately no longer favoured by dental practitioners in Africa.
Some other common traditional oral health practices in Africa include extraction of primary canine, removal of lower central incisors in adults, brushing of
children gingival with fresh herbs and cosmetic hole-drilling of upper lip of girls for cosmetic dressing (Ogunbodede, 1991). 59
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
(c) African Medicinal Plants in the World Market

Many plant drugs even in the crude form are well known in the international markets today and African countries are among the top world producers of such plants (Table 3). Examples are Rauwolfia vomitoria Afz., (Family Apocynaceae) which is a major source of reserpine, a major tranquilizer and an antihypertensive; ginger (Zingiber officinale) Roscoe (Family Zingiberaceae) which contains gingerol used as spice, carminative and important medicinal product. Ginger is also produced in Nigeria. Capsicum annum Linn. (Family Solanaceae) produces capsain and capsacin, used as spice and medicine; Physostigma venenosum Balf. (Family Leguminoceae) which is the Calabar bean, produces physostigmine or eserine used in ophthalmia; Syzigium aromaticum Linn. (Family Myrtaceae) is a dental remedy and also Chrysanthemum cinerariifolium Vis (Family Asteraceae), called pyrethrum flower, produces the natural pyrethrins, a class of insecticides (Wallis, 1967). Others include Catharanthus roseus (Linn.) G. Don (Family Apocynaceae), also called the Vinca or Madagascar Rose periwinkle, used in the management of leukaemia and Hodgkin’s disease; Agave sisalana Perrine (Family Agavaceae), exported by Tanzania and is rich in hecogenin, employed for the partial synthesis of steroidal drugs such as corticosteroids and oral contraceptives; also Cinchona succirubra Pav. (Family Rubiaceae) which yields quinine, a key antimalarial drug of long history (Reiz and Lipp, 1982). In addition, there are several other medicinal plants of research interest in several parts of Africa strongly qualified for drug development. A few examples are presented in Tables 2 and 3.
(d) The Challenges of Plant drug Utilization in Africa
Obviously, drug development from natural sources is not all a bed of roses. Infact, it can be much more Herculean than synthetic drug development. Formulation

of herbal medicines, particularly in crude-drug form, represents a specialized expert area that requires training and experience. The heavy microbial load resulting from the field plant contamination as well as stability and shelf life determination in terms of stabilization and preservation, particularly in liquid dosage forms, would pose important fundamental challenges. Packaging materials must be carefully selected to withstand all possible natural colour deterioration as well as chemical, microbial and environmental contamination. The heavy demands of large-scale manufacture, which may rely on wild source collection, would pose the challenge of large-scale cultivation and conservation of different plant species. The problems of scientific evidence for the proofs of efficacy and the possibility of chronic toxicity for herbal medicines give reasonable and logical basis for reservation. Proven protocols for clinical monitoring (e.g. Plasmodium count in malaria, fasting and random blood sugar determination, etc.)
as well as organized and affordable clinical trials, must be addressed objectively in herbal drug development. However, with serious attention, energy, resource mobilization, commitment and the required political will, the various challenges can be successfully addressed. Such ideals have since been achieved in India and China, as well as in other developing countries of the world. For several centuries now and up till today, Cassia acutifolia (Senna) leaves known as Herb Tea of Commerce, remains a product of large-scale cultivation and collection, in Egypt and Sudan, although they are packaged in London and sold back to Africa; sourcing of quinine from Cinchona bark 60
Afr. J. Trad. CAM (2005) 2 (1): 46- 61
or diosgenin from Discorea tubers continues in India as two separate large-scale cultivation and collection ventures. Hundreds of Chinese herbal preparations have already been developed with established standard methods of formulation for quality, stability and adequate shelf-life while many of them, including injections, have been subjected to high-level, sophisticated clinical testing for toxicity and efficacy. China and India started several decades ago from somewhere. It is high time, African countries where similar natural resources abound followed their footsteps using the natural forest endowment for self-reliance, international recognition, and economic liberation in health care financing.
The current interest surge in herbal medicines all over the world (both developed and developing countries), leading to the unregulated cropping of the Africa’s bioresources, will pose stress and threat of extinction on the plant species while the traditional healers themselves are hopelessly being observed to advance in age and gradually disappearing from the surface of the earth. Therefore, the situation of both plant and human resource extinction must set a natural deadline for all of us the African pharmacognosists, pharmacologists, dentists, pharmacists and physicians to learn, acquire, document and use traditional medicine knowledge for the benefits of Africa and its people, and indeed the entire mankind (Elujoba, 2003). Since no single system of health can solve all the problems, there is need for African biomedical Scientists to adopt an open mind with due respect, towards our traditional health beliefs and practices. An official respect, by the orthodox practitioners, duly accorded to the spiritual, nutritional and socio-cultural components of physical healing, with the body’s potentials to heal and maintain itself is highly essential at this stage in Africa.
There is also the need for orthodox doctors in Africa to be knowledgeable about the positive aspects of Traditional Medicine in order to appreciate the vast areas of research open to them for self-development and for service in the health care delivery system of our people. The oral health and dental scientists must equally be challenged not to shy away from Traditional Oral Health Practices but rather, to examine critically,
the advantages and disadvantages, in order to come up, through studies and research, with some balanced and fair conclusion for the overall benefits of the African people. This, as a vital component of societal expectation, ought to be the collective responsibility of all the African medical scientists.

PROPOSALS FOR A CLEAN ENERGY INVESTMENT FRAMEWORK FOR AFRICA: Role of the African Development Bank Group

PROPOSALS FOR A CLEAN ENERGY INVESTMENT FRAMEWORK FOR AFRICA: Role of the African Development Bank Group

Executive Summary

1. Climate change has emerged as an important challenge facing Africa and, indeed, much of the world in the 21st century. In the light of the mounting evidence of its causes and effects, the Heads of State and Government of the G8 States, at their Gleneagles Summit in July 2005, called upon the World Bank and other multilateral development banks (MDBs) to prepare specific proposals to address three inter-related challenges: expanding access to reliable energy supplies particularly for the world’s poor; promoting investment in clean energy and low-carbon approaches to economic
development; and supporting developing countries in undertaking concrete measures to adapt to climate
change and strengthen their capacities to manage increasing climate variability and extreme weather
events .

2. This framework paper contains the response of the African Development Bank to the request of the G-8. It presents a comprehensive framework for dealing with the challenges of increasing energy access; at the same time, making maximum use of clean energy options in Africa. The paper focuses on the energy aspects. It deals with the key issues, challenges, opportunities as well as the resource requirements and the role the Bank will play in expanding energy access and developing clean energy – contributing to global climate change mitigation efforts – in its regional member countries (RMCs).

However, work also continues in parallel to develop the AfDB Group’s Climate Change Risk Management Strategy. Indeed, Senior Management has reviewed and approved a Concept Note on the preparation of the strategy. The full report is expected early 2008. All aspects of the energy access, climate change mitigation, and adaptation challenges will then be addressed holistically in an Action Plan on Clean Energy and Climate Change that will be finalized by mid 2008.

3. Expanding energy access is a priority for Africa. Rational long-term planning taking into account economic, social and environmental costs would increasingly shift the balance in favour of a low-carbon path to development and poverty reduction. As one of the regions most vulnerable to global warming, Africa has a vested interest in rendering effective support for global mitigation efforts. The continent has a number of options for clean energy development with enormous potential. African countries, especially in Sub-Sahara Africa, need to make greater use of their huge largely untapped renewable energy potential – especially hydro-power, geothermal energy, solar and wind power, and more efficient
utilisation of biomass. The development of such energy options could be financed in part by sale of CDM-certified carbon emission credits.

4. Financing requirements for clean energy are enormous and call for concerted efforts by development partners and governments alike. The Bank Group will endeavour to provide financing through its concessional and non-concessional windows. With a view to mobilising greater resources for the continent, the Bank will seek greater leverage for its resources by working more closely with RMCs on creating enabling policy and institutional environments conducive to private sector investment. To the same end, the Bank will build stronger collaboration with partner institutions. As the unique multilateral financing institution dedicated exclusively to Africa, the AfDB is in a position to take on the role of providing coordination, brokerage and syndication services to RMCs, bilateral and multilateral institutions, and private development partners, in support of energy access and low-carbon development strategies. This paper proposes the
creation of a multi-donor trust fund on clean energy access and climate adaptation for Africa, to spearhead Bank support to RMCs on the three challenges, including provision of pre-investment support at the national and sub-regional level. As part of the follow-up actions, Management will commission a feasibility study on creating the proposed facility.
5. The Boards of Directors are invited to approve the proposed Clean Energy Investment Framework for Africa and the timeline of activities as outlined in this report

WOMEN, WATER AND HYGIENE ARE KEY TO CHANGE IN AFRICA

WOMEN, WATER AND HYGIENE ARE KEY TO CHANGE IN AFRICA

Services for Women & Girls Must Be Priority for Water and Sanitation

NEW YORK, 14 September 2005 - Women, water and basic hygiene are the key to creating lasting change in Africa, but national water and sanitation plans are still leaving women out,leaders in development said today.
UNICEF Executive Director Ann M. Veneman joined other prominent women, including Hilde Frafjord Johnson, Norway’s Minister for International Development, to call for more attention and funds to help the millions of African women and girls suffering disproportionately for lack of these basic services.
“Unsafe water, inadequate sanitation and poor hygiene habits play a major role in child mortality,” said UNICEF Executive Director Ann M. Veneman. “Bringing basic services to Africa’s women and girls could transform their lives and boost child survival in the region.”

Veneman said she is joining Minister Johnson and Minister Maria Mutagamba, Uganda’s Minister of State for Water, in the Women Leaders for Water, Sanitation and Hygiene (WASH) initiative.
Launched last year by the Water Supply and Sanitation Collaborative Council (WSSCC), Women Leaders in WASH helps governments to link women with sanitation and hygiene programmes,and supports the UNICEF drive to put safe water and basic sanitation into all primary schools by 2015. The group is meeting at UNICEF today to set out a plan of action for Africa.
Lack of safe water and sanitation remains one of the world’s most urgent health issues. Some 1.1 billion people worldwide still lack safe water and 2.6 billion have no sanitation, according to a UNICEF and World Health Organization 2005 report Water for Life.
Sub-Saharan Africa is the only region likely to miss Millennium Development Goal (MDG) targets on both safe water and basic sanitation, unless the world acts quickly to turn this around. MDG 7 calls on countries to reduce by half the number of people living without these basic services. But despite good progress in some countries, currently only 58 per cent of Africans live within 30 minutes walk of an improved water source and only 36 percent have even a basic toilet.
The consequences are particularly severe for African women and children, condemning millions to a life of illness, lost opportunities and virtual slavery.
In rural Africa, 19 per cent of women spend more than one hour on each trip to fetch water, an exhausting and often dangerous chore that robs them of the chance to work and learn. Women without toilets are forced to defecate in the open, risking their dignity and personal safety.
Education suffers too: more than half of all girls who drop out of primary school do so for lack of separate toilets and easy access to safe water.
Unsafe water, inadequate sanitation and poor hygiene habits play a major role in Africa’s high child mortality rate. Diarrhoea is the third-biggest child killer in Africa after pneumonia and malaria, accounting for 701,000 child deaths out of 4.4 million on the continent every year. It also leaves millions of children with a legacy of chronic malnutrition, the underlying cause of over half of all child mortality. The burden of caring for sick relatives inevitably falls to women and girls,
keeping them at home and shutting them out of economic development.

Bringing relief to women and girls will result in better services for all and benefit entire communities, said Minister Johnson and Minister Mutagamba.
“Women can be key agents of change if they are empowered and involved,” said Minister Johnson. “Since they are the primary victims of unsafe water and poor sanitation, we must start with them if we are to liberate Africa from cycles of illness, child mortality and low productivity.”
“In Uganda, we saw how rapidly school attendance can rise and illness fall when schools have safe water and separate toilets for boys and girls,” said Minister Mutagamba. “There is no excuse not to put these effective and sustainable interventions into practice everywhere.”

Veneman, Johnson and Mutagamba hailed the great progress made by many poor countries as
proof that water and sanitation goals are achievable everywhere. They called on Millennium
Summit leaders to commit to a strong action plan for the next decade.
