With past and continued destruction of primary forest worldwide, secondary forest constitute a large and growing component of forest cover and have been found to be very important for a wide range of goods and services.

Tailandia

Swidden farming is the main agent of conversion of primary forests to secondary forests in the highlands of mainland Southeast Asia, but there is a deterioration and decline of the practice with land use intensification. The population growth in northern Thailand has forced lowland farmers practising permanent wet rice cultivation to turn to short rotation swidden in the foot hill zone. Highland swidden agriculturists are adopting more intensive forms of swidden or are shifting to permanent farming.

Much of mainland Southeast Asia's primary forest has been converted into secondary vegetation types in the past several decades. In the Lower Mekong Subregion, nearly 100 million ha of forest were significantly altered or removed, with depletion in terms of areal percent most severe in Thailand and Vietnam. Timber extraction and conversion of forestland to agriculture are the two principal causes of forest degradation in the region. Logged sites are often later occupied by migrant homesteaders. The current regional focus of logging has shifted to Laos, Cambodia and Myanmar.

Self-governance and forest resources

Journal Articles & Books
Diciembre, 1999

Forest resources share attributes with many other resource systems that make difficult their governance and management in a sustainable, efficient and equitable manner. Destruction or degradation of forest resources is most likely to occur in open-access forests where those involved, or external authorities, have not established effective governance. Conventional theories applied to forest resources presumed that forest users themselves were incapable of organizing to overcome the temptations to overharvest.

África austral

Five themes are identified for social, economic and policy research relating to miombo woodland management in southern Africa. They are: (1) patterns of local institutional change; (2) household use of woodland products; (3) markets for woodland products; (4) longer term dimensions to woodland use and exploitation and (5) policy and legislation. These themes are by no means definitive or exhaustive, but are described here as a means of focusing on the scope of future research, and as a basis for identifying priorities.

Technology will help to address the challenges for sustainable forestry in the 21st century. Some of the challenges will include the shift of production from native forest to plantations in areas of comparative advantage, more efficient processing delinking end-use products from raw wood characteristics, increased demand, better information technologies to support decision makers, and more options for conserving biodiversity.

Journal Articles & Books
Diciembre, 1996

This report documents the conduct of the first field tests of criteria and indicators (C&I) at the forest management unit level. Interdisciplinary and international teams of five persons conducted tests of five sets of C&I in four countries (Germany, Indonesia, Brazil, and Cote d’Ivoire). This report provides a description of the methods used, a thorough analysis of the findings, a combined generic template of C&I dealing with production forestry, policy, social and ecological issues, based on the groups’ results.

Burkina Faso

La gestion durable des ressources naturelles, notamment dans les pays du Sahel, a toujours soulevé des problèmes dont celui de l’inadaptation des législations nationales y relatives. Le processus d’élaboration et de mise en œuvre de ces législations est à l’image des conditions politiques, socio-économiques et culturelles des pays en question. Le Burkina Faso, pour sa part, a connu plusieurs formes de régimes politiques et, de ce fait, capitalise un certain nombre d’expériences de réformes législatives et réglementaires dans le secteur des forêts et des ressources naturelles.
