O tema do mercado de terras integra a agenda contemporânea das políticas agrárias, tanto no Brasil como em outros países. No caso brasileiro, decorre da história de ocupação do território e da própria formação social e econômica que produziram um quadro de ilegalidade, de instabilidade jurídica e de fragilidade institucional.

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.

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.

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.

The Little Green Data Book 2005 is based on the World Development Indicators 2005, and represents an abbreviated collection of information. Its production is a collaboration between the Development Economics Data Development Group, and the Environment Department of the World Bank. Development and poverty alleviation-the World Bank's mission-call for a long-term vision.

Paul Wolfowitz, President of the World Bank, shared his thoughts about how the global community can face the double challenge of protecting our environment and strengthening our economies.

It may come as a paradox that while interest in tropical forests worldwide has been steadily growing in the last century, this has in no way halted the continued loss and degradation of one of earth's grandest terrestrial ecosystems. In fact, the extent and rate of degradation is accelerating.

Globally, according to FRA 2000, planted forests accounted for only 5% of forest area, but up to 35% of industrial roundwood supply. This is anticipated to rise to 40-44% by 2020. Planted forests reflect a higher social, environmental and economic importance than their area would suggest.

This study examined the efficiency of programs supporting the conservation of forest resources and services through direct payments to land owners; or payments for environmental services (PES). The analysis is based on a sample of farms receiving and not receiving PES in the Osa Peninsula, Costa Rica.
