The productivity of semi-arid rangelands on the Arabian Peninsula is spatially and temporally highly variable, and increasing grazing pressure as well as the likely effects of climatic change further threatens vegetation resources.

Human–elephant conflict in India, driven by habitat loss and an expanding human population, is a complex challenge for biodiversity conservation. Determining if, how and why this conflict has changed over time will be an important step towards managing landscapes where people and elephants Elephas maximus coexist.

This paper assesses strategic water availability and use under different development pathways on a basin scale using remote sensing (RS), geographical information systems (GIS) and a spatial water budget model (SWBM).

A desirable feature of a global sampling design for estimating forest cover change based on satellite imagery is the ability to adapt the design to obtain precise regional estimates, where a region may be a country, state, province, or conservation area. A sampling design stratified by an auxiliary variable correlated with forest cover change has this adaptability.

In megacities water quantity and quality are threatened by complex and interrelated processes caused by population growth, land use change, unsustainable agricultural practices, deforestation, erosion, destruction of ecosystems, lack of planning, laissez-faire policies, unsustainable water management, political conflicts, and increasingly also by the impacts of climate change.

Insular Southeast Asia experienced the highest level of deforestation among all humid tropical regions of the world during the 1990s. Owing to the exceptionally high biodiversity in Southeast Asian forest ecosystems and the immense amount of carbon stored in forested peatlands, deforestation in this region has the potential to cause serious global consequences.

Questions: Which are the factors that influence forest and shrubland loss and regeneration and their underlying drivers? Location: Central Chile, a world biodiversity hotspot.

Over the last decade, hundreds of payments for ecosystem services (PES) programmes have been initiated around the world, but evidence of their environmental benefits remains limited. In this study, two PES programmes operating in the municipality of Coatepec (Mexico) were evaluated to assess their effectiveness in protecting the region's endangered upland forests.

This report examines whether the recent increase in biofuel feedstock production is resulting in increased deforestation rates and magnitudes within tropical regions. It reviews several methodological challenges for undertaking this analysis, and presents a set of preliminary findings.

Significantly increased rates of deforestation in Indonesia from the 1970s to the 2000s have brought pressure on law enforcement agencies to better enforce the law and prosecute forest crimes. Generally, criminal wrongdoing in the forestry sector is only prosecuted under the provisions of the Forestry Law.

Agriculture needs to feed 9 billion people by 2050. This will require a 70 100% increase in food production (Godfray et al. 2010). Given climate change, a new kind of agriculture is therefore essential, one that must meet the triple challenge not only of ensuring food security, but also of adapting to future climate change and contributing to climate change mitigation.

Agroforestry and other tree-based systems (wood lots, afforestation) can contribute to Reducing Emissions from Deforestation and Forest Degradation (REDD+) in two ways: 1) as part of REDD+ under certain forest definitions; and / or 2) as part of a strategy for achieving REDD+ in landscapes.
