This region covers the central part of Zambia extending from east to west, and comprises the sandveld plateau of Central, Eastern, Lusaka, and Southern provinces (Subregion 2a), and the Kalahari sand plateau and the Zambezi flood plains in Western province (Subregion 2b). Region 2 receives a well-distributed annual rainfall of between 800 and 1000 mm. The growing season ranges from 100 to 140 days with one to three 10-day dry periods of less than 30 mm of rainfall, which reduces crop yields, especially on sandy soils. However, in normal years, favorable climatic conditions and good soils make the region the most productive in Zambia. Mean daily temperatures during the growing season range from 23°C to 25°C. Severe frost may be experienced in some parts of Region 2 in June to August. The main soils in agroecological Region 2 have slight to severe chemical and physical limitations for crop production. They include low water-holding capacities, shallow rooting depth, low organic matter, low nutrient reserve and acidity, crusting, and coarse-textured topsoils that increase erosion hazard. The soils are clayey, loamy, or sandy, and strong to medium acidity. The vegetation type is varied and dominated by miombo and munga woodland, and to a lesser degree Kalahari woodland (dry deciduous forests), and dry evergreen forest.
