Abstract

The hydrological cycle, which determines the water balance of the grazing ecosystem, is discussed. This cycle can be separated into a number of intermediate processes, each of which influences the water balance. These intermediate processes include surface runoff, evapotranspiration, percolation, infiltration and the storage of water in the ecosystem. Practical guidelines to increase the effectivity of the available rainfall for aboveground phytomass production, in arid and semi-arid regions, are discussed.
