Multiple land-use designs are becoming increasingly necessary in semi-arid Africa as growing populations focus numerous production systems onto spatially limited arable lands. Engineering distinct land uses into a single area ideally requires that land-use components complement each other, and operate in predictable magnitudes. Quantitative evaluations of components to be included in multiple land-use designs are necessary to determine both how components would [`]fit' together, and how these would serve populations participating in distinct production systems. With data gathered in Somalia, this study considers a design in which fodder-producing trees and irrigated agriculture could be integrated. Following a discussion of the benefits of such an integration, this analysis focuses on a quantitative examination of potential livestock carrying capacity from Acacia albida trees in an irrigated area. Comparisons are made with observed livestock numbers in order to determine if such a design could accommodate the seasonal influx of nomadic herds. The land-use elements that comprise carrying capacity are themselves examined to see which elemens might be managed to offset or take advantage of those which are not easily managed.
