The Great Apes, including the chimpanzee, gorilla and orangutan, are threatened with extinction. All species are rapidly declining in abundance, even within protected areas.The main factors responsible for this decline are loss and degradation of habitat, and hunting. Construction of roads in forest areas is particularly damaging, as such development facilitates hunting and other activities which lead to habitat destruction.
This report assesses the impact of infrastructural development on great ape populations, using the GLOBIO modelling approach. GLOBIO is a multivariable spatial model, which estimates the extent of land area with reduced abundance and diversity of living organisms, as a result of infrastructural development. The model can also be used to develop scenarios of possible future impacts, based on the current rates of infrastructural development.Resource Type: Reports
The Last Stand of the Orangutan was prepared by a Rapid Response Team at UNEP/GRID-Arendal and UNEP World Conservation Monitoring Centre as a broad collaborative effort, involving contributors from the Ministry of Environment and Ministry of Forestry, Indonesia, and partners of the Great Apes Survival Project (GRASP).Resource Type: Reports
This report presents the results of a study into potential overlap between extractive industries (mining, oil and gas) and natural World Heritage sites. At the time of this study, the UNESCO World Heritage (WH) List included 217 properties recognized for their natural Outstanding Universal Value. UNEP-WCMC, with inputs from a number of partners, conducted an analysis at the global level of the association between the IHS and SNL global datasets on extractive activities and natural WH sites. Noting the inherent limitations of using global data for site-scale analysis, the resulting report provides statistical and geographical data on the extent of potential overlap indicated by the global extractives datasets. The report provides discussions and conclusions and suggests possible next steps.Resource Type: Reports
