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.

This special issue of Unasylva has two main objectives. It brings to our readers an edited selection of some of the position papers of the important 4th Session of the FAO Committee on Forestry Development in the Tropics and, in doing, this, it emphasizes FAO's principal concern in the field of forestry: how to make the best and wisest use of man's least understood ecological formation, the moist tropical forest.

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 Many countries have existing planted forest data that is not based upon forest inventory, is incomplete and often outdated.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.

This document is the second part of a two part manual on local level assessment of land degradation and sustainable land management: ? Part 1 ? Planning and Methodological Approach, Analysis and Reporting ? Part 2 ? Field Methodology and Tools The two parts should be used together as Part 1 provides the background information for the conduct of the methods and tools that are provided in Part 2.

this MFW will be an approach to restoration which requires coordination between sectors intended to promote productive multifunctional territories characterised by an optimal balance negotiated with local actors in terms of supply of economic, social and environmental benefits. This internationally-recognized vision for Forest and Landscape Restoration (FLR) allows the promotion of synergies between the three Rio conventions and can contribute to the Sustainable Development Goals (SDG).

Para que produzcan los resultados apetecidos, las actividades de ordenacin de cuencas hidrogrficas han de incorporar hidrologa forestal, conservacin de suelos y aguas y planificacin del uso de la tierra en un marco lgico ms amplio que tome en consideracin no slo los fenmenos fsicos, sino tambin los factores econmicos, sociales e institucionales. En este nmero, Unasylva examina varios aspectos de la ordenacin de cuencas hidrogrficas.

This publication contains key messages from the International Conference on the Economics of Climate Change Mitigation Options in the Forest Sector, organized by FAO and held online in February 2015.

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.
