Supporting Soil Health Consortia in West Africa - facilitating wider uptake of better adapted ISFM practices with visible positive impacts on rural livelihoods: final narrative report
The present study uses georeferenced community level data to study the adoption of improved cowpea in northern Nigeria. One objective of this study is to find out which factors of the community of village level are significant determinants of adoption of improved dual-purpose (DP) cowpea variatie...

Low-cost animal drawn implements for Vertisol management and strategies for land use intensification
The main aim of land preparation is to modify and manipulate the land features so as to create favorable environment for seed establishment and crop growth. The research and Development in this field must take into account the traditional practices used by the farming community. This case study g...

Low cost animal drawn implements for Vertisol management and strategies for land use intensification
This chapter discusses the traditional tillage implement and the alternative tillage implements using animal power in Vertisol management. Among the topics of discussion are land shaping equipment; the ridge and furrow system; minimum tillage with BBM attachments; animal drawn scoops; pond excava...
Reports a concerted interinstitutional attempt to generalize the use of the available draught animal power for the construction of more effective soil surface drainage. The hypothesis is that the relatively high productive potential of the Ethiopian highland vertisols, particularly in high-rainfa...

Improving productivity on highland Vertisols: The oxen-drawn broadbed maker
This chapter reviews relevant Vertisol properties, experimental results and the overall experience of the project on this subject. There are several types of drainage problems in Vertisols whose magnitude may vary from site to site. Drainage improvement is discussed in relation with camber beds, ...
