Agriculture is fundamental to achieving nutrition goals: it produces the food, energy, and nutrients essential for human health and well-being. Gains in food production have played a key role in feeding growing and malnourished populations. Yet they have not translated into a hunger-free world nor prevented the development of further nutritional challenges. Micronutrient deficiencies (for example, of vitamin A, iron, iodine, and zinc) are now recognized as being even more limiting for human growth, development, health, and productivity than energy deficits.

Malaria, schistosomiasis (bilharzia), and Japanese encephalitis are the major vector-borne diseases whose increase or decrease can be attributed to agricultural water development (see table). Others include dengue fever, yellow fever, and filariasis. Young children in poor communities are particularly affected: malaria is among the top five causes of death among under-fives in Sub-Saharan Africa; schistosomiasis among children affects growth, nutritional status, and cognitive development; and encephalitis occurs mainly in young children...

Policymaking initiatives in agriculture and public health are often pursued in a parallel and unconnected fashion. Yet coherent, joint action in agriculture and health could have large potential benefits and substantially reduce risks for the poor. Among development professionals there is growing recognition that agriculture influences health, and health influences agriculture, and that both in turn have profound implications for poverty reduction.

This case study explores the development, dissemination, adoption, and impact of improved tree fallows in rural western Kenya. The processes of technology development and dissemination throughout the region are described and analyzed. To analyze adoption and impact, the paper applies a variety of different data collection methods as well as samples from both pilot areas where researchers maintained a significant presence and non-pilot areas where farmers learned of the technologies through other channels.

"Good health and productive agriculture are both essential in the fight against poverty. In a rapidly changing world, agriculture faces many challenges, both old (natural resource constraints, extreme weather conditions, and agricultural pests) and new (globalization, environmental degradation, problems of maintaining production in conflict situations). At the same time, new global health threats emerge, such as HIV/AIDS, SARS, and avian influenza, while old ones persist.

"To end hunger and prevent the recurrence of famine and starvation, we need to take the following steps: invest in public health, child nutrition, education, women’s and girls’ social status, and other components of human capital; reform public institutions and create innovative funding and partnership arrangements; change government policies at all levels to be both pro-poor and pro-growth; increase funding for scientific and technological research to boost agricultural production and efficiency; and develop specific policies and institutions to deal with environmental degradation caused

Contrairement aux prévisions communément admises quant à l’aggravation du déclin économique de l’Afrique, une récente étude présente une vision alternative plus positive de l’avenir de ce continent. De nouveaux engagements politiques, une gestion du programme de développement sous égide africaine ainsi que l’accroissement de l’intérêt et des investissements dans les petites exploitations agricoles ont le potentiel d’arrêter, voire d’inverser la tendance spiroïdale de la famine, de la pauvreté, de la dégradation environnementale, des maladies et des guerres civiles.

En las últimas décadas, el mundo ha hecho un progreso impresionante para mejorar la calidad de vida de millones de personas; sin embargo, todavía sigue inconclusa la tarea de garantizar la seguridad alimentaria a los más pobres de una manera sostenible. La explosión demográfica, la expansión urbana, la desnutrición y la mala salud persistentes, las tierras agrícolas degradadas y el agua escasa, la carencia de poder de las mujeres, la globalización acelerada y la rápida aparición de nuevas tecnologías - todos estos y muchos otros factores están influenciando este esfuerzo continuo.

"In contrast to popular predictions of Africa’s worsening economic decline, recent research supports an alternative and more positive vision of Africa’s future. New political commitment and African ownership of the development agenda, combined with a renewed focus on and investments in smallholder-led agriculture, have the potential to halt or reverse the current downward spiral of hunger, poverty, environmental degradation, disease, and civil strife.

This book brings together briefs and articles generated by the 2020 Vision initiative that remain highly relevant to the ongoing dialog and debate and, given the nature of the topics addressed, are likely to remain so for some time to come.

The workshop participants were clear that now is the time for choices, and that without the will to make those choices, the likelihood of success in boosting agricultural growth on a sustained basis would be small. Without such growth, it will not be possible to improve food security or halt natural resource degradation. It seems unlikely that all countries of Africa will choose to put in place the necessary conditions for growth, which makes it all the more important to decide at the outset which conditions are most likely to beget further success.
