The watershed services provided by tropical natural and planted forests are critical to human well-being. An increasing number of valuation studies and experiences with payment for ecosystem services have dealt with the role of ecosystems in regulating the flow of water. However, several studies ...

Caractériser la surface terrestre est important pour analyser la diversité des paysages et pour appréhender les changements d'utilisation du sol. En général, dans les cartographies de végétation de l'Amazonie et du plateau des Guyanes, la forêt est représentée sous la forme d'une grande couche ve...

The objective of this study was to evaluate the effect of N fertilization and the presence of N2 fixing leguminous trees on soil fluxes of greenhouse gases. For a one year period, we measured soil fluxes of nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4), related soil parameters (temp...

People’s perceptions of their environment in high mountain rangelands ultimately affect the fragile ecosystems on which they depend, and thus their welfare. This is especially true in developing countries, where the livelihoods of people living in such ecosystems depend on grazing livestock. The ...

Vulnerability assessment is increasingly recognised as a starting point to identify climate adaptation needs and improve adaptive capacity. However, vulnerability assessments are challenging because of the complexity of multifaceted biophysical, human and institutional factors, interacting at dif...

Environmental changes must be initiated by forest harvesting. The harvesting of timber has affected forest ecosystems in various ways which includes degradation, shortage of forest water supply, soil loss and green house gas emission. Selective cutting, clear-cut, fire and burning are major cause...

This articles included in this special section focus on the ecological and economic interactions of woodland use in Western Zimbabwe. One of the aims was to investigate the use of modeling to achieve integration among disciplines. The integrated model draws on the models in the different papers c...

Under natural resource ecosystems shared across communities and nations, the distribution among stakeholders of risks and vulnerability to climate change is likely to be uneven on account of the nature of their stakes in the ecosystems, the degree of their dependence and the extent of degradation...

The concept of payments for ecosystem services (PES) is probably the most promising innovation in conservation since Rio 1992, slowly but certainly to expand in the tropics. In a global context of stagnating or even decreasing public funding for biodiversity conservation, PES have the potential b...
