The AQUASTAT Programme was initiated with a view to presenting a comprehensive picture of water resources and irrigation in the countries of Africa, Asia, Latin America and the Caribbean and providing systematic, up-to-date and reliable information on water for agriculture and rural development. This report presents the results of the most recent survey carried out in the 18 countries of the Middle East region, and it analyses the changes that have occurred in the ten years since the first survey.

En conclusion, des informations actuelles, fiables et transparentes sur le secteur forestier sont un ingrdient vital du processus d'amnagement durable. Toutes les organisations et institutions engages dans la gestion durable des forts devraient exploiter les moyens offerts par Internet pour coordonner et relier les serveurs et optimiser ainsi la valeur des informations disponibles. Comme promis dans la prcdente dition, ce numro d'Unasylva contient de nouveaux articles sur le dveloppement durable des montagnes, qui viennent ainsi complter le tour d'horizon de la question.

The global reproduction of food, notably cereal crops, appears to have been remarkably resilient to the vagaries of climate. The unsung hero in this production chain may well be groundwater. When rainfed agriculture fails, the fallback is usually groundwater. First it is accessed to smooth over the dry periods, and then it becomes a habit. Therefore, staying within strict resource limits would seem to be the obvious piece of management advice.

This field manual contains definitions and procedures used to plan and perform a national forest inventory and assessment following the approach developed by the Forest Resources Assessment programme (FRA) of the FAO. The methodology, based on nation-wide field sampling, has already been tested and implemented in several countries since year 2000 (Costa Rica, Guatemala, Philippines, Cameroon and Lebanon).

This manual is designed to give detailed, practical advice on the various methodologies of organic recycling. Blue-green algae form a self-sufficient system which is capable of fixing atmospheric nitrogen in organic forms and which grows upon a free water surface. It is thus ideally suited for propagation in rice fields. The development and use of blue-green algae require special techniques. The manual summarizes the present status of algal biofertilizer technology for rice with practical information for its adoption by agricultural extension personnel and subject matter specialists.

Le prsent numro d'Unasylva est principalement consacr l'Afrique. Une bonne partie du continent a t ravage par plusieurs annes successives de scheresse, et des millions d'tres humains souffrent de faim et de malnutrition. Dans de nombreux pays d'Afrique, les cultures empitent rapidement sur les forts et les zones arides cause de la famine.

Community-based natural resource management and local users of natural resources can, and in many cases do, manage resources sustainably – if their rights to do so are recognized and protected, if appropriate institutions are in place or can be developed, and if the benefits are significant, obvious and secure. The article analyses one facet of the complex relationship between law and community-based management: the problem of how national laws recognize community-based land-owning or resource managing groups.
