El presente nmero de Unasylva se centra en Africa. Gran parte de ese continente ha sido afectado por la sequa durante varios aos consecutivos y millones de personas estn hoy expuestas al hambre y la malnutricin. En muchos pases la agricultura est invadiendo terrenos forestales y zonas de escasas precipitaciones. Este hecho, unido a una explotacin desordenada de la lea, los forrajes y otros bienes y servicios bsicos que pueden obtenerse de los bosques y los rboles, ha provocado una deforestacin cada vez ms rpida.

Un rapport complet, long de quarante-trois pages qui traite de l'état général des données sur les ressources forestières en Mauritanie.

There is a urgent need for a better understanding of the risks of soil degradation and their geographical distribution as well as a better knowledge of where degradation occurs at present. it would be desirable to combine soil conservation activities with other elements for increasing crop production.Erosion, salinity and alkalinity and the loss of soil fertility seriously reduce the natural potential of soils to produce food fibres. During the meeting, many criteria to assess the various types of soil degradation were outlined by the experts.
