"This paper describes the emergence of improved traditional planting pits (zaï) in Burkina Faso in the early 1980s as well as their advantages, disadvantages and impact. The zaï emerged in a context of recurrent droughts and frequent harvest failures, which triggered farmers to start improving this local practice. Despair triggered experimentation and innovation by farmers. These processes were supported and complemented by external intervention. Between 1985 and 2000 substantial public investment has taken place in soil and water conservation (SWC).

This brief describes two case studies as follows: "Sub-Saharan Africa, with the highest fertility rate in the world, faces increasing demographic pressure on its natural resource base.... Old strategies for coping with these new pressures on the natural resource base are becoming increasingly infeasible... Consequently, Africa's farmers require new solutions to address the increasing pressure on the continent's soil and water resources. Among hundreds of innovative efforts across the continent, two promising sets of responses have emerged in different locations....

La dégradation des ressources naturelles est devenue un problème mondial qui menace les moyens d’existence de millions de pauvres. De nombreuses technologies très prometteuses sont actuellement disponibles, notamment en matière de gestion des ressources naturelles, mais les exploitants agricoles et les autres intervenants hésitent souvent à les employer. Pourquoi? Bien que de nombreux facteurs puissent l’expliquer, l’absence de droits de propriété garantis et l’insuffisance d’actions collectives devrait retenir l’attention des décideurs et des développeurs
de technologie.

"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

"Degradation of natural resources has become a global problem that threatens the livelihood of millions of poor people. Many promising technologies for natural resource management are available to address these problems, but farmers and others often fail to adopt them. Why is this? Although many factors can be identified, lack of secure property rights and collective action deserve greater attention from policy makers and technology developers.

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.
