a) Agroecologies

A full characterization of the climate and soils, predominant farming systems, population pressure and livestock numbers, and the environmental threats for semi-arid and sub-humid dryland agroecologies of SSA and SA is provided by Hyman et al. (2016) ⁴⁷. The regions, agroecologies, commodities and farming systems considered are presented in Figure 1 and Table 1.
