Overgrazing, leading to pasture degradation and soil erosion, commonly called 'desertification', is certainly widespread, although the reliability of information about it is very low. A key problem is to sustain livestock through the long dry season. 18 LAND RESOURCE ISSUES Management of the livestock is not well integrated with conservation of the pastures on which they depend. Population pressure leads to the encroachment of arable cultivation onto grazing land, often the moister and most valuable pastures.
Under communist rule, land resource management was often not efficient or sustainable, conservation was sacrificed to the achievement of production targets, and serious degradation occurred. In some respects, many of the smaller republics in Central Asia now belong to the develop- LAND RESOURCES ing world. Aid funds have been diverted to this region. For this group of countries, it will be assumed that: political stability and efficient government, and consequent economic progress, will be maintained; there will be some further population increase, and a substantial rise in living standards leading to greatly increased consumer demand, including for food; arising from better land resource and economic management, food production will increase, although not sufficiently to make this bloc a net food exporter.
