Abstract

Multitemporal 1 km NOAA/AVHRR Normalized Difference Vegetation Index (NDVI) maximum composite imagery was utilized in combination with rainfall, soil types, and field survey data on dominant rural activities to assess the risk of land degradation in southern Mauritania.

This study evaluates the relationship between landscape accessibility and land cover change in Western Honduras, and demonstrates how these relationships are influenced by social and economic processes of land use change in the region. The study area presents a complex mosaic of land cover change processes that involve approximately equal amounts of reforestation and deforestation.

This exploratory study was designed to capture the main features of agrarian change in the upper part of the basin that depends mostly on anicuts. These anicuts amount to 59 percent of the total basin anicuts in terms of numbers, but to only 43 percent in terms of irrigated area.

Fires are considered a potential threat to sustainable development for their direct impacts on ecosystems, their contribution to carbon emissions, and impacts on biodiversity. In 1997/98, Indonesia had the most severe fires worldwide, and smoke haze pollution recurs yearly.

Gabon’s oil wealth coincides with the fact that it is one of the most forested countries in Africa; about four-fifths of its land area is covered by forests. But this is not really a coincidence.

The purpose of this lecture note is to summarise different research results about the impact of macro-level factors and “extra-sectoral” policies on tropical forest cover. Specifically, we are interested in the forest margins - i.e. the spatial transition zone between tropical forests and converted land uses.

Summary: China’s trade in timber products with Myanmar grew substantially from 1997-2002, from 295,474 m3
(round wood equivalent, RWE) in 1997 to 947,765 m3 (RWE) in 2002. Despite increased volume,
timber product imports from Myanmar comprised only 2.5% of China’s total timber product imports
