Abstract
Humans have been altering land cover since pre-history through the use of fire to flush out game and, since the advent of plant and animal domestication, through the clearance of patches of land for agriculture and livestock. In the past two centuries the impact of human activities on the land has grown enormously, altering entire landscapes, and ultimately impacting the earth’s nutrient and hydrological cycles as well as climate. Land-use and land-cover changes are local and place specific, occurring incrementally in ways that often escape our attention. Yet, collectively, they add up to one of the most important facets of global environmental change. This thematic guide provides an introduction to these changes, and walks the readers through important topics in land-use and land-cover change research: deforestation, desertification, biodiversity loss, land cover and the water cycle, land cover and the carbon cycle, and urbanization.
