HarvestChoice is a research initiative which generates information to help guide strategic investments in agriculture aimed at improving the well‐being of poor people in Sub-Saharan Africa through more productive and profitable farming. The initiative is coordinated by the International Food Policy Research Institute (IFPRI) and the University of Minnesota and is supported by a grant by the Bill & Melinda Gates Foundation.
Total Livestock Units are livestock numbers converted to a common unit (in 2005). Conversion factors are: cattle = 0.7, sheep = 0.1, goats = 0.1, pigs = 0.2, chicken = 0.01. Factors taken mostly from http://www.lrrd.org/lrrd18/8/chil18117.htm, except for cattle. See also http://en.wikipedia.org/wiki/Livestock_grazing_comparison (aggregation type: SUM).
