Agricultural innovation has played a critical role in the economic transformation of developing East Asian countries over the past half century. The Green Revolution—in the form of modern seed varieties, chemical fertilizers, pesticides, and modern machinery—has contributed to increased crop yields and farm incomes, and decreased poverty across the region. Although policy makers’ traditional focus on expanding and intensifying agricultural production has brought many benefits, the focus on productivity has come at a rising cost.
The rapid transformation of agri-food value chains in Africa and other developing countries has important implications for economic growth and poverty reduction. Policy makers increasingly recognize this but there is a need for a better understanding of what value chain transformation entails and what the main policy options are. This paper provides an overview and analysis of different value chain models that have emerged in the past decades and reviews the literature on the main development implications.
Many countries are facing growing levels of food insecurity, reversing years of development gains, and threatening the achievement of Sustainable Development Goals by 2030. Even before COVID-19 reduced incomes and disrupted supply chains, chronic and acute hunger were on the rise due to various factors, including conflict, socio-economic conditions, natural hazards, climate change and pests.
L' étude de la Banque Mondiale a identifié des mesures d’atténuation pouvant apporter des solutions à court et à long termes aux problèmes du secteur agricole du Niger. Il s’agit, notamment de :
l’utilisation de variétés à haut rendement résistantes à la sécheresse,
l’application de techniques de CES/DRS et de gestion des ressources naturelles,
l’extension des surfaces sous irrigation,
la lutte préventive contre les criquets pèlerins,
Le Niger compte parmi les pays les plus vulnérables au monde en raison du contexte lié à son climat, ses institutions, ses sources de revenus, son économie et son environnement. La pauvreté y est omniprésente et le pays se classe au bas de l’échelle sur la quasi-totalité des indicateurs de développement humain. L’agriculture est le secteur le plus important de l’économie du Niger. Elle représente plus de 40 pour cent du le produit intérieur brut national et constitue la principale source de revenus pour plus de 80 pour cent de la population.
Farmers in Asia like to grow cassava because the crop will tolerate long dry periods and poor soils, and will produce reasonable yields with little inputs. Most farmers realize, however, that cassava production on slopes can cause severe erosion, while production without fertilizer inputs may lead to a decline in soil productivity. Research has shown that cassava yields can be maintained for many years with adequate application of fertilizers, and that there are various ways to reduce erosion.

Farming systems in Vietnam are undergoing rapid change, including increased levels of commercialisation and market integration, adoption of (or desire for) labour efficient technologies, and migration of youth in response to non-farm work opportunities. These processes are not only shaping rural landscapes and communities, but challenging traditional gender roles.
This booklet is the third in the CIAT in Asia Research for Development series. It was based on the experiences of researchers and farmers working with the AusAID-funded Forages for Smallholders Project (FSP) in Southeast Asia from 1995 to 1999. This project was a partnership of smallholder farmers, development workers and researchers who were using participatory approaches to developing forage technologies on farms.
This chapter explores the interrelationships between economic change and environmental issues, by showing how aspiration, education, and migration are variously connected to a loss of agroecological knowledges for rural young people. It reviews a series of case studies from Vietnam, India, and China on the implications for rural youth of changed aspirations and ecological and economic stress. The economic and cultural pressures of globalization mean young people increasingly aspire for a life outside of agrarian- and natural resource-based livelihoods.
