Nations, village communities and individual land users need to make choices about land use in order to support development without risk of land degradation. Computerized land information systems (LIS) based on geographic information systems (GIS) have emerged as powerful tools for generating maps and reports to inform such decisions. Recently, FAO has been developing GIS/LIS systems in linkage with its agroecological zoning (AEZ) and other models, and using them to tackle issues of land, food and people at global, national and subnational levels. They have been successfully developed for land resource management at different scales, but practical difficulties have been encountered in making them accessible to the casual user in most developing countries, due to scarcity of data and poor training support.

The Tropics

By 2000 AD approximately 84 per cent of the world's arable cropland will rely on rainfall. Throughout developing countries the yields of many rain-fed farmers are falling and their ability to sustain production seems uncertain. Land degradation must be halted, security of harvests improved, and wherever necessary yields increased, crops diversified, and the area cultivated extended. For the most cultivators some form of improved rain-fed agriculture is likely to be the only practical route to such goals.
