A conceptual framework for evaluating cross-breeding programmes in sub-Saharan Africa is developed based on a Kenyan case study. It depicts livestock production as a system where farm animals, plants, land and water are interlinked in particular ways and are also interlinked with the environment....

This paper first discusses the need to assess the economic impact of livestock diseases and their control. It then examines the conceptual framework for assessing the economic impact of diseases and their control. This is followed by a brief explanation of some of the economic concepts behind the...

In Ethiopia and Kenya, a unit of credit given to a credit-constrained farmer has twice as much effect on agricultural productivity as a unit of credit given to a farmer with adequate access to financial resources, according to a recent ILRI study. The study also found that giving farmers agricult...

Certain landscapes in the Sahel and elsewhere consist of a 'checkerboard' arrangement of vegetated and non-vegetated areas in which there may be several spectrally distinct vegetation and bare ground components. When individual components form large spatially coherent patches, and the vertical di...
