The WOCAT-LADA-DESIRE mapping tool is based on the original WOCAT mapping questionnaire (WOCAT, 2007). It has been expanded to pay more attention to issues such as biological and water degradation, it also places more emphasis on direct and socio-economic causes of these phenomena, including their impacts on ecosystem services. It evaluates what type of land degradation is actually happening where and why and what is being done about it in terms of sustainable land management (SLM) in the form of a questionnaire.

Globally, according to FRA 2000, planted forests account ed for only 5% of forest area, but up to 35% of industrial roundwood supply. This is anticipated to rise to 40-44% by 2020. Planted forests reflect a higher social, environmental and economic importance than their area would suggest. Many countries have existing planted forest data that is not based upon forest inventory, is incomplete and often outdated. Thus it is difficult to measure and plan the quantity and quality of planted forest resources and the provision of goods and services that they supply.

Extensive grazing is the predominant form of land use on at least a quarter of the world’s land surface, in which livestock are raised on food that comes mainly from rangelands. Extensive grazing differs from crop or forestry production, in which the produce remains in situ whilst growing. Evaluation for extensive grazing, unlike that for cropping or forestry, must take into account the production of both grazing forage, termed primary production, and the livestock that feed on this forage, termed secondary production.

Les forêts méditerranéennes d’Algérie, Liban, Maroc, Tunisie et Turquie couvrent une superficie totale de près de 19 millions d’hectares. Ces forêts ont été et seront soumises de manière croissante à des pressions anthropiques (surpâturage, collecte de bois de chauffe, incendies, conversions agricoles, etc.) et aux effets dus au changement climatique (augmentation des températures et de la fréquence des événements extrêmes, diminution des précipitations, attaques parasitaires, etc.) Ainsi, des phénomènes de déforestation et de dégradation forestière sont observés.

This publication has been prepared as a background paper in view of the UN conference on the human environment that was held in Stockholm in 1972. This background document had contribution from UNESCO, IAEA and WHO. While the demand for land for land increases at a very rapid rate through population growth, technological progress and industrial development, soil resources remain fixed. The maintenance of their productivity is therefore of paramount importance.
