As part of the Sustainable Development Goals, countries are striving to achieve by 2030 a land degradation neutral world. Land degradation neutrality (LDN) is the state whereby the amount and quality of land resources remains stable or increases within specified temporal and spatial scales. Achieving this will require the uptake of sustainable land management (SLM) practices to increase the…

The Puna region, located in NW Argentina, is a dry highland with many endemic species and significant traditional cultural heritage. The Puna was a pilot region for the Land Degradation Assessment in Drylands project (LADA-FAO) which aimed at assessing desertification status in different land use systems (LUS). The results of these assessments are used for reporting to the United Nations…

The article presents a review of environmental degradation and its threats in China. Air pollution, water pollution, deforestation, soil degradation, sand depositing in dams, decaying urban infrastructure, and more and more hazards such as floods, landslides and soil erosion are major consequences of environmental degradation and are making tremendous loss both in life and property. …

Desertification has been defined as land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities (United Nations, 1992). A technique for identifying and assessing areas at risk fordesertification in the arid, semi-arid, and subhumid regionsof the United States was developed by the Desert Research…

The deterioration of land resources in the world's arid and semi-arid regions is one of the gravest problems facing our planet and its people. Desertification, broadly defined, is one of the principal barriers to sustainable food security and sustainable livelihoods in our world today. It is not a future global threat; it is a devastating day-to-day local reality. If we aspire to provide…

A considerable amount of scientific and technological literature containing basic information on the ecology of arid lands has been accumulated during recent years. But whereas this scientific and technological information provides solutions to many of the problems of desertification, and such solutions have been applied with success in a number of advanced countries, this has not been the case…
