There is a lack of reliable data on land degradation but it is likely that soil degradation has affected some 1 900 million hectares of land worldwide (UNEP/ISRIC 1991). The largest area affected, about 550 million hectares, is in Asia and the Pacific. In China alone, between 1957 and 1990, the area of arable land […]
A wall of dust stretched from northern Queensland to the southern tip of eastern Australia on the morning of September 23, 2009, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image. The dust is thick enough that the land beneath it is not visible. The storm, the worst in 70 […]

The […]
The Nile Delta is under threat from rising sea levels. Without the food it produces, Egypt faces catastrophe By Jack Shenker …Today, however, Nile water barely reaches this corner of the Delta.

At least 45% of Indian land is environmentally “degraded”, air pollution is rising and flora and fauna is diminishing, according to a report. The State of Environment Report is the first to be published for eight years and is the first to use satellite imagery to support its findings. It focuses on water, energy, food, […]
(Wiley-Blackwell) A new study published in the journal Soil Use and Management attempts for the first time to measure the extent and severity of land degradation across the globe and concludes that 24 percent of the land area is degrading — often in very productive areas. Land degradation – the decline in the quality […]
