La sécheresse qui sévit dans le Sahel depuis les années 1970 a fortement réduit les productions dans les principaux secteurs d’activités que sont la pêche, l’élevage et l’agriculture. Dans le Delta Intérieur du Niger au Mali (DIN), la pêche dont le développement est intimement lié aux fluctuations inter-saisonnières et interannuelles de la crue du fleuve Niger, est en crise. Les prises ont diminué de moitié, beaucoup de pêcheurs sont partis, certains ont adopté des pratiques non durables et les règles sociales subissent d’importantes modifications.
Rendir un informe anual del trabajo realizado por el IICA es más que un compromiso con la transparencia y la rendición de cuentas; constituye también un medio para reconocer los avances de nuestros Estados Miembros en beneficio de sus pueblos. Los logros que ellos alcanzan gracias a los aportes que les brinda el Instituto los hace mantener su confianza en una organización que de hecho les pertenece.
L’agroécologie s’inscrit dans le registre de l’écologie, qui s’intéresse aux interactions - et à leurs conséquences - entre l’homme et son milieu, en tentant de minimiser les effets négatifs de certaines des activités humaines. Elle vise la préservation de l’environnement, le renouvellement durable des ressources naturelles nécessaire à la production (eau, sol, biodiversité...) et l’économie d’utilisation des ressources non renouvelables.
This paper documents a positive relationship between maize productivity in western Kenya and women’s empowerment in agriculture, measured using indicators derived from the abbreviated version of the Women’s Empowerment in Agriculture Index. Applying a cross-sectional instrumental-variable regression method to a data set of 707 maize farm households from western Kenya, we find that women’s empowerment in agriculture significantly increases maize productivity.
Low and slow adoption of improved agricultural technologies among smallholders often frustrate technology development and promotion efforts in the developing world. That is especially true for technologies requiring high initial investment. This study investigates how increasing farmers' awareness and exposure to new agricultural technologies through the creation of systematic linkages in the research-to-development continuum affect adoption. The double hurdle and duration analysis models were applied to a sample of 820 smallholder households producing wheat and barley in Syria.
While livestock constitute a strategic sector to reduce poverty and enhance growth in developing countries, decision makers often lack data reflecting the diversity of livestock functions and systems. The authors therefore mobilised the Livestock Sector Investment Policy Toolkit to assess the economic contributions of livestock in Zambia. Valuing their plural contributions by system, we found that mixed rainfed systems were the main contributors to added value, even if specialised intensive systems provided around 45% of meat and milk production.
Agroforestry (AF) systems have been the focus of numerous research and development projects in southern Africa, yet their adoption rate generally remains low. Employing on-farm, participatory research techniques in southern Malawi, was compared the suitability of three AF-based systems that relay crop the dominant staple, maize (Zea mays), with the perennial legumes Sesbania sesban, Tephrosia vogelii, and Cajanus cajan (pigeonpea).
Given the increasing tension between food production and food demand in sub-Saharan Africa, as well as the poor development of the rice sector in Africa, the present paper examines the impact of agricultural extension on adoption of chemical fertilizers and their impact on rice productivity in Ghana. A parametric approach was employed to account for selectivity and endogeneity effects, which most impact studies fail to address. The empirical results reveal that agricultural extension service is endogenous in the chemical fertilizer adoption specification
