"Degradation of natural resources has become a global problem that threatens the livelihood of millions of poor people. Many promising technologies for natural resource management are available to address these problems, but farmers and others often fail to adopt them. Why is this? Although many factors can be identified, lack of secure property rights and collective action deserve greater attention from policy makers and technology developers.

Australia's 'Landcare' program is a community-based participatory program established by government to tackle the problem of land degradation. Landcare involves thousands of Australians working together in locally based groups, tackling problems of common concern. Government and community are now looking to 'scale up' the Landcare idea to a regional level. State and territory governments have moved to create regional (often watershed-based) frameworks for land management planning and resource conservation, in accordance with the concept of integrated watershed management.

Agroforestry can help prevent land degradation while allowing continuing use of land to produce crops and livestock. A problem with the evaluation of agroforestry using long-run static models and traditional discounting techniques is that the present value of the forestry enterprise is generally much lower than that of other production activities. This problem is common with Australian native species which tend to have a high environmental value but a low market value.

A consequence of the European colonization of Australia has been a significant ioss of biodiversity: one in four mammal species is either extinct or threatened. In contrast, only one species of bird has been lost from the Australian continent and there is less concern for the survival of the Australian avifauna than for mammals. This is despite the fact that nearly one in five bird species is listed as threatened or of “special concern”.

Cette etude a ete realisee en 1997-98 par le CIFOR en collaboration avec les institutions et les chercheurs camerounais, grace a l'appui financier du DFID du Royaume-Uni. Son objectif general est de compendre les causes qui expliqueraient le taux de deforestation beaucoup plus elevependantla crise economique (qui commenca en 1986) par rapport a ala periode avant le debut de la crise. Le project de recherche a examine les effects de la crise sur les migrations, les systemes de cultures, la division sexuelle du travail et leur incidence sur le couvert forestier.
