¿Es mejor, y se administra mejor, un bosque con 1 000 especies que un bosque con 500 especies? Este número de Unasylva trata de cuestiones relacionadas con la diversidad biológica forestal y su conservación y uso sostenible. Una de las conclusiones básicas es que los números no son lo único que importa.

This study investigates the political and contentious nature of access to mountain natural resources by poor, disadvantaged and marginalized people, including women and youth, and the policy processes associated with access and development over time. This study has been commissioned by FAO to look at sustainable livelihoods approaches to access to natural resources in mountain areas. We concentrate on access by poorer and marginalized groups to policy processes whereby long-term sustainable access to resources is achieved.

The survey of tropical forests reported here was developed and implemented with the aim of providing detailed and reliable information on the process of on-going chenges in the tropical forest cover, in order to meet the needs of researchers, policy makers and the public at large.

Improved forest harvesting practices, with due consideration of the forest environment, are considered an important step towards sustainable forest management, particularly in tropical regions. The present case study has been carried out with one of the numerous small concession holders operating in the "Forest Belt" of Suriname. It could be demonstrated that even with a minimum effort in planning of harvesting operations, a significant advantage of meeting not only economic but also environmental objectives can be achieved.
