Land use change is one of the main stress factors on ecosystems near urban areas. We analysed land use dynamics within Xochimilco, a World Heritage Site area in Mexico City. We used satellite images and GIS to quantify changes in land use/land cover (LULC) from 1989 to 2006 in this area, and a Markov projection model to simulate the impact of different management scenarios through to 2057. The results show an alarming rate of urbanisation in 17 years. LULC change runs in one direction from all other land use categories towards urban land use.

Nitrate and pesticide leaching led to the designation of groundwater protection zones in Denmark. The protective measures in these zones often clash with local interests in agriculture. Scenarios were used to evaluate the development of a groundwater protection zone in a farming area. Stakeholders are accorded strong influence on the scenarios. Scenario inputs comprised land cover, land use and farmers' plans and preferences, as registered in interviews with farmers. Scenarios were evaluated regarding the effect on nitrate leaching, extent of pesticide-free area and farm income.

The question of how smallholders of the Amazon estuary, locally known as cabolcos , have adapted their land use systems to produce resources during booms and busts is analyzed in this article. We draw upon more than 50 years of census data and more than 30 years of remotely sensed land-cover data to reconstruct these dynamics from World War II to the present.

OTALEX II is the Territorial and Environmental Observatory of Alentejo (Portugal) and Extremadura (Spain), co-financed by POCTEP, developed with the cross-border collaboration of several Portuguese and Spanish bodies. It is composed of a Spatial Data Infrastructure (SDI) created in 2007, SDI-OTALEX (www.ideotalex.eu), which is an exchange platform for geographic information and Webmapping services among project partners.

This study analysed long-term land-use and land-cover change (LUCC) in a highland watershed covering an area of about 154 km² in the Blue Nile basin of Ethiopia. Two sets of panchromatic aerial photographs (1957 and 1982) and a Landsat TM image (2001) were the main input data from which three land-use and land-cover maps were produced by employing geographical information systems/remote sensing techniques. These data were complemented by some socio-economic data that were generated by using household survey, key-informant interview and group discussion methods.

Placing conservation within a broad framework of agrarian and environmental politics, this review article argues that natural resource governance is fundamental to rural politics in China. Much of the environmental literature adopts a technocratic approach, ignoring the political nature of the redistribution of access to and control over natural resources, and of knowledge vis-à-vis degradation.

India’s sustained and rapid economic
growth offers an opportunity to lift millions out of
poverty. But this may come at a steep cost to the nation’s
environment and natural resources. This insightful book
analyzes India’s growth from an economic perspective and
assesses whether India can grow in a “green” and sustainable
manner. Three key issues are addressed. The first is the
physical and monetary costs and losses of environmental
