Natural resources management in African agriculture: understanding and improving current practices.

Book cover for Natural resources management in African agriculture: understanding and improving current practices.

Description

This book synthesizes existing information on the adoption of natural resource management investments and strategies (such as soil fertility improvements or erosion control) for agriculture in sub-Saharan Africa. It also critically examines current analytical methods and generates research and policy recommendations. Topics covered include: farmers' objectives and learning processes; willingness a...

Evaluating adoption of new crop-livestock-soil-management technologies using georeferenced village-level data: the case of cowpea in the dry savannahs of West Africa.

This study uses georeferenced community-level data to study the adoption of improved cowpea (Vigna unguiculata) in northern Nigeria. One objective of the study is to find out which factors at the community or village level are significant determinants of adoption of improved dual-purpose (DP) cowpea varieties and management techniques. The implications for those attempting to catalyse dissemination of the new varieties and related management techniques are explored. A second objective is to estimate the amount of cowpea currently being grown in the two Nigerian states included in the study (Kano and Jigawa) and to extrapolate to a wider area suggested by the study findings (i.e., places with similar agricultural potential, population density and market access across West Africa). Results suggest that, for improved cowpea varieties to become and remain popular in all locations, they must first be high-grain yielding; secondly, pest resistant; and, thirdly, yield enough fodder to support the crop-livestock enterprises in which each and every family in the study area is involved. The adoption of improved DP varieties appears to be a 'win-win' situation with respect to improvements in natural resource management in intensive, integrated crop-livestock systems, particularly soil fertility. Those more market-oriented producers more interested in selling the cowpea grain leave the residues to rot in the fields, adding nutrients to the soil. Those that prefer the DP types and feed the residues to their animals return a significant amount of nutrients to the soil via the manure.
