Locations reported by various studies as undergoing high rates of land cover change in the past few decades Locations reported by various studies as undergoing high rates of land cover change in the past few decades
In the case of forest cover change, the studies refer to the period 1980–2000 and are based on national statistics, remote sensing, and to a limited degree expert opinion. In the case of land cover change resulting from degradation in drylands (desertification), the period is unspecified but inferred to be within the last half-century, and the major study was entirely based on expert opinion, with associated low certainty.

Development of organic matter, phosphorus and nitrate in EU 15 rivers Development of organic matter, phosphorus and nitrate in EU 15 rivers
The graphic shows the development of organic matter, phosphorus and nitrate in EU 15 rivers. Water resources in Europe have been profoundly influenced over the past century by human activities, including the construction of dams and canals, large irrigation and drainage systems, changes of land cover in most watersheds, high inputs of chemicals from industry and agriculture into surface and groundwater, and depletion of aquifers. Some of the most...

Tea Production Areas and Forest Distribution in Kenya Tea Production Areas and Forest Distribution in Kenya
The micro-climate associated with forest areas is often a critical factor in growing cash crops. In East Africa, tea is grown in areas adjacent to montane forests where conditions for tea production are optimal due to constant moisture levels, air temperatures between 10° and 30° C and soil temperatures between 16° and 25° C. The high moisture levels in these montane forests combined with the high heat capacity of water reduces the day...

Land cover - Baltic Sea region Land cover - Baltic Sea region
The Baltic Sea region is covered in primarily forested land and crop land, in the taiga and temperate forest regions. Agricultural land is a main driver for nutrient inputs to the Baltic Sea, and thus eutorphication, and is thus relevant. Forest lands acts as a net buffer for nutrients, unless it is heavily diked and/or fertilised.

Land cover - Baltic Sea region (BALANS) Land cover - Baltic Sea region (BALANS)
The Baltic Sea region is covered by primarily forested land and cropland. This land cover map, delineated for the Baltic Sea drainage basin, is using the dataset prepared through the BALANS project, and represents the situation around year 2000.

Land cover changes in desert areas 1700,1900,2000 and 2050 Land cover changes in desert areas 1700,1900,2000 and 2050
The main land use change in desert areas has been the conversion of relatively barren drylands for agricultural needs, partially through irrigation. The conversion has historically primarily been to use the land for grazing, but the 2050 scenario suggests that small areas on the fringes of deserts will be converted to cropland. The model otherwise predicts modest changes for 2050.
