Increased global demand for land underscores the need for well-designed, country-level land policies to protect long-held rights, facilitate land access, and address constraints to growth. However, reforms are often technically complex, politically sensitive, and time consuming. It is thus…

Land deals are frequently agreed in secret between governments and investors. This lack of transparency in the allocation of land fosters an environment where elite capture of natural assets becomes the norm, where human rights are routinely abused with impunity, where environmental destruction…

Across the world, ‘green grabbing’ – the appropriation of land and resources for environmental ends – is an emerging process of deep and growing significance. The vigorous debate on ‘land grabbing’ already highlights instances where ‘green’ credentials are called upon to justify appropriations…

Global conservation discourses and practices increasingly rely on market-based solutions to fulfill the dual objective of forest conservation and economic development. Although varied, these interventions are premised on the assumption that natural resources are most effectively managed and…

Global knowledge about the spatial distribution of species is orders of magnitude coarser in resolution than other geographically-structured environmental datasets such as topography or land cover. Yet such knowledge is crucial in deciphering ecological and evolutionary processes and in managing…

It has been widely accepted that ecosystem services (ESs) should be taken into account in natural resource management decisions. Hence, there is an increasing need for innovative quantification methods and tools to evaluate ESs on different landscape scales, and under varying land-use forms.…

The density and diversity of woody plant species were studied within grazing, cultivation and charcoal production land-use areas in a multiple-use savanna woodland, central Uganda, using 75 plots with an area of 0.1 ha (Whittaker plots). Plant density was significantly higher under charcoal…

The compilation of global Landsat data-sets and the ever-lowering costs of computing now make it feasible to monitor the Earth's land cover at Landsat resolutions of 30 m. In this article, we describe the methods to create global products of forest cover and cover change at Landsat…

Urban land-cover change threatens biodiversity and affects ecosystem productivity through loss of habitat, biomass, and carbon storage. However, despite projections that world urban populations will increase to nearly 5 billion by 2030, little is known about future locations, magnitudes, and…

Global climate models (GCM) investigating the effects of land cover on climate have found that replacing extra-tropical forest with cropland promotes cooling. We compared cropland and forest surface temperatures across the continental United States in 16 cells that were approximately 1°×2° using…

Water temperature and discharge are fundamental to lotic ecosystem function, and both are strongly affected by climate. In large river catchments, however, climatic effects might be difficult to discern from background variability and other cumulative sources of anthropogenic change arising from…

Global agriculture lies in intersection of two inescapable issues of the present times, viz. keeping pace with growing food demand and participating in climate change mitigation efforts. Rice cultivation is a major emitter of greenhouse gases (GHGs) and no tillage of soil is becoming popular due…
