Understanding the extent of these changes is important for regional sustainable land management. An integrated approach with a geographic information system and remote sensing was used to extract land use/land cov...

The semi-arid grasslands in Inner Mongolia (IM) are under increasing stress owing to climate change and rapid socio-economic development in the recent past. We investigated changes in land cover/land use and landscape structure between 1992 and 2004 through the analysis of AVHRR and MODIS derived land cover data. The scale of analysis included the regional level (i.e. the whole of IM) as well a...

Forest fragmentation occurs when a contiguous patch of forest is transformed into disjunct patches. This reduces the quality of habitat for bird species of ecological and recreational importance, and is considered to be a primary cause of declines in the populations of many migratory songbirds. In this paper, we analyze the effects of market-based policies on forest fragmentation in the coastal...
