LADA (Land Degradation Assessment in Drylands project) is a scientifically-based approach to assessing and mapping land degradation at different spatial scales ? small to large ? and at various levels ? local to global. It was initiated in drylands, but the methods and tools have been developed so as to be widely applicable in other ecosystems and diverse contexts with minimal required adaptation.

Le suivi et l'évaluation sont essentiels pour mesurer les progrès réalisés et les impacts biophysiques et socio-économiques des activités menées dans le cadre d'Action contre la désertification. Le S&E aide également Action contre la désertification à obtenir des résultats en veillant à ce que les objectifs soient clairement définis et réalisables, que la collecte de données soit correctement planifiée et que les données soient utilisées pour la prise de décision et pour l'amélioration continuelle du programme.

This issue of Unasylva focuses on Africa. A large part of the continent has been overrun by drought in successive years, and millions of people are exposed to hunger and malnutrition. In many African countries, cultivation is because of hunger - rapidly expanding into forest land and areas of low rainfall. This process, coupled with necessarily unmanaged exploitation for fuelwood, fodder and other basic goods and services that forests and trees provide, has led to a progressively increasing rate of deforestation.

Los tcnicos forestales y los administradores de recursos naturales entendieron muy poco y mal los mltiples usos que los campesinos hicieron de las formaciones forestales en el curso de los milenios, ampliamente documentados en un artculo sobre las tcnicas de ordenacin de tierras arboladas aparecido en el nmero 160 de Unasylva.

Monitoring and Evaluation (M&E) are essential to keep track of the progress made and to measure the bio-physical and socio-economic impact of the activities carried out under Action Against Desertification. M&E also helps Action Against Desertification deliver results by making sure that the objectives are clearly defined and achievable, that data collection is well planned and that data are used for decision-making and to continuously improve the programme.
