Tropical deforestation in Southeast Asia is one of the leading causes of carbon emissions and reductions of biodiversity. Spatially explicit analyses of the dynamics of deforestation in Indonesia are needed to support sustainable land use planning but the value of such analyses has so far been limited by data availability and geographical scope. We use remote sensing maps of land use change fro...

BACKGROUND Historic carbon emissions are an important foundation for proposed efforts to Reduce Emissions from Deforestation and forest Degradation and enhance forest carbon stocks through conservation and sustainable forest management (REDD+). The level of uncertainty in historic carbon emissions estimates is also critical for REDD+, since high uncertainties could limit climate benefits from c...

BACKGROUND Reserves are the principal means to conserve forests and biodiversity, but the question of whether reserves work is still debated. In the Amazon, fires are closely linked to deforestation, and thus can be used as a proxy for reserve effectiveness in protecting forest cover. We ask whether reserves in the Brazilian Amazon provide effective protection against deforestation and conseque...

Increasing awareness of the issue of deforestation and degradation in the tropics has resulted in efforts to monitor forest resources in tropical countries. Advances in satellite-based remote sensing and ground-based technologies have allowed for monitoring of forests with high spatial, temporal and thematic detail. Despite these advances, there is a need to engage communities in monitoring act...

a r t i c l e i n f o Deforestation is a leading cause of biodiversity loss and an important source of global carbon emissions. This means that there are important synergies between climate policy and conservation policy. The highest rates of deforestation occur in tropical countries, where much of the land at the forest frontier is managed informally by smallholders and where governance system...

The aim of this thesis was to estimate the cost of deforestation and to identify its drivers in the high forest zone of Ghana. The purpose was also to raise awareness about the severity of deforestation and to offer suggestions for its control with a view to contributing to climate change mitigation. To compute the cost of deforestation, the values of four ecosystems’ services were estimated, e...

Tropical deforestation is of growing concern to the world community. Global effects associated with this process include loss of biodiversity and changes in the carbon cycle. Although the importance and present severity of these two externalities are subjects of intense controversy, few would deny the cata­ strophic nature of their potential impacts. Deforestation also poses local and regional ...

To reduce greenhouse gas emissions from deforestation, Indonesia instituted a nationwide moratorium on new license areas ("concessions") for oil palm plantations, timber plantations, and logging activity on primary forests and peat lands after May 2011. Here we indirectly evaluate the effectiveness of this policy using annual nationwide data on deforestation, concession licenses, and potential ...

fragmentation, or breaking apart of habitats, is one of the major causes of decline in biological diversity. mature ecosystems, especially dense forests are very sensitive to this phenomenon and roads are one of the major causes of fragmentation in forest landscapes. present investigation aims to trace landscape fragmentation in dense forests of golestan national park in northeast of iran betw...
