Suitability for small-scale farming and potential yield (crops/y) of Nile tilapia (suitability_farming_potential_yield_tilapia)

Map derived from the combined suitability of areas apt for small-scale fish farming development and operation with areas with potential yield (crops/y) of Nile tilapia for small-scale farming. Areas with suitability for small-scale fish farming were derived from the combined suitability of four land-quality factors important for fish farming development and operation; net annual water requirement for shallow ponds, soil and terrain suitability for the construction of fish ponds, potential livestock wastes and agriculture by-products as feed and fertilizer inputs, and potential for farm-gate sales. Predictions of growth were based on water temperature, in turn predicted from air temperature and wind velocity data. Gridded values of mean monthly daily minimum and maximum temperatures were obtained from the Centre for Resource and Environmental Studies (CRES) at the Australian National University. Mean annual wind velocity was obtained from UNEP/DEIA/GRID-Geneva.
