Definition and distribution of the arid and semi-arid zones

As stated, for the purpose of this report an exact definition of aridity is unnecessary, and the areas principally considered are those recognized as arid (350-500 mm annual rainfall) and very arid (200-350 mm) by the Government of Kenya (1979), although some of the discussion refers equally to semiarid areas (500-800 mm). The 500 mm isohyet is shown in figure 2 (page 3), the total area receiving less than 500 mm rainfall being 379,000 km².
