Book Description
Focusing on mixed crop-livestock farming systems of sub-Saharan Africa, this review brings together the available knowledge in the various components of the livestock and water sectors. Through an analysis of livestock-water interactions, promising strategies and interventions to improve Livestock Water Productivity are proposed. In the biophysical domain, the numerous interventions relate to feed, water and animal management. These are interlinked with interventions in the socio-political-economic domain. The paper identifies critical research and development gaps in terms of methodologies for quantifying water productivity and integrating different scales, and also in terms of institutions and policies.

Book Description
In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

Book Description
Traditional linkages between ruminant livestock (cattle, sheep and goats) and soil productivity in the West African Sahel is reviewed, and the adequacy of such practices in light of changes taking place in the region is assessed. Suggestions are given for ways in which nutrient cycling could be improved and made part of a broader strategy to enhance sustainable crop-livestock production
