Using the Horn of Africa as an example, the maps illustrate different steps in a methodology developed to estimate and map the economic benefits to livestock keepers of controlling a disease (Shaw et al. 2014). Cattle are first assigned to different production systems as shown in Map 1, illustrating for example, where mixed farming is heavily dependent on the use of draft oxen in Ethiopia, areas of Sudan and South Sudan where oxen use is much lower, and the strictly pastoral areas of Somalia and Kenya.

Agroecological zones (AEZs) are geographical areas exhibiting similar climatic conditions that determine their ability to support rainfed agriculture. At a regional scale, AEZs are influenced by latitude, elevation, and temperature, as well as seasonality, and rainfall amounts and distribution during the growing season.

Across Africa buying and selling connects people. For a small-scale farmer, this trade takes place primarily within a limited geographic area based on access to market centers of a given size. The maps illustrate these areas using different colors to represent marketsheds—geographical areas and associated populations that are part of real or potential trade networks with a given market. From any location within a marketshed, it takes less time to travel to the corresponding market compared to any neighboring markets.
