Synopsis Land use for sustainable productivity involves environmentally sound approach, so that the resource base is maintained or enhanced for future generations. The mounting pressure of human and animal populations and increased crop/biomass production through modern technologies have not been sustained by the land resources of arid regions. Concerned about this mounting pressure on the scarce resources of the arid lands, UNESCO sponsored a training programme on "Land Resources and their Management for Sustainability in Arid Regions" at CAZRI. This compendium is an outcome of that training programme. The contents of the book include the concept of sustainability, land resources constraints in the arid regions, their vulnerability to degradation and sustainable management of land resources through agriculture, horticulture, silviculture and pasture development.
