desertification
1) The development of desert conditions as a result of human activity or climatic changes.
2) The process of land damage which allows the soil to spread like a desert in arid and semi-arid regions. There is a loss of vegetative cover and the soil deteriorates in texture, nutrient content and fertility. Desertification affects the lives of three-quarters of the world's population, 70 % of all drylands and one quarter of the total land area of the planet. There are many reasons for desertification, but the majority are caused by human activities, overgrazing, deforestation, poor land management and over-exploitation. Agenda 21 states that the priority in combating desertification should be establishing preventive measures for lands that are not yet, or are only slightly, degraded.

mountain ecosystem
Ecosystems found on high-mountains at low latitudes. Mountain ecosystems are very vulnerable. They are increasingly sensitive to soil erosion, landslide and rapid loss of habitat and genetic diversity. Widespread poverty and an increase in the numbers of mountain inhabitants lead to deforestation, cultivation of marginal lands, excessive livestock grazing, loss of biomass cover and other forms of environmental degradation. Because little is known about mountain ecosystems, Agenda 21 has proposed the establishment of a global mountain database. This is essential for the launch of programmes that would contribute to the sustainable development of mountain ecosystems. The proposals also focus on promoting watershed development and alternative employment for people whose livelihoods are linked to practices that degrade mountains. (Source: WRIGHT)
