Climate sensitivity to tropical land surface changes with coupled versus prescribed SSTs

Journal Articles & Books
Décembre, 2005
Afrique

Tropical land cover change experiments with fixed sea-surface temperatures (SSTs) and with an interactive ocean are compared to assess the relevance of including the ocean system in sensitivity studies to land surface conditions. The results show that the local response to deforestation is similar with fixed and simulated SSTs. Over Amazonia, all experiments simulate a comparable decrease in precipitation and no change in moisture convergence, implying that there is only a change in local water recycling.

Analysis of deforestation patterns in the Baekdudaegan preservation area using land cover classification and change detection techniques; the feasibility of restoration

Journal Articles & Books
Décembre, 2005

The Baekdudaegan Mountain Range is a backbone of the Korean Peninsula which has special spiritual and sentimental significance for Koreans and significant ecological value to diverse organisms. Despite the importance of this region, however, the natural environment of Baekdudaegan has been severely threatened by a variety of human activity and tremendous forest fires. To make management and restoration plans for the deforested areas, it is necessary to investigate quantitatively such natural and human-induced physical changes.

Deforestation and Shade Coffee in Oaxaca, Mexico: Key Research Findings

Mexique

More than three-quarters of Mexico's coffee is grown on small plots shaded by the existing forest. Because they preserve forest cover, shade coffee farms provide vital ecological services including harboring biodiversity and preventing soil erosion. Unfortunately, tree cover in Mexico's shade coffee areas is increasingly being cleared to make way for subsistence agriculture, a direct result of the unprecedented decline of international coffee prices over the past decade.

The report describes the impacts of forestry decentralization on district finance, local communities and spatial planning, drawing on an 18-month research project in Bulungan District in East Kalimantan Province. It describes forestry management policies following the implementation of regional autonomy, and their impacts on district revenue and local livelihoods. The authors analyze district spatial planning, forest land use and community control over forest lands.

Asia du sud-est

Local people in South-east Asia are often cited as skilled forest managers. It is barely acknowledged that an essential part of this forest management does not concern natural forests, but forests that have been planted, often after the removal of pre-existing natural forests; forests that are cultivated not by professional foresters, but by sedentary or swidden farmers, on their farmlands; forests that are based not on exotic, fast-growing trees, but on local tree species, and harbour an incredible variety of plant and animal species.
