Geographical division of global lands into “ecoregions”
The population growth of humanity has increased globally by 34 %, leading to an estimated population of 9.1 billion people by 2050 which will raise the demand for food products by 70 %. (FAO 2009) The distribution of population growth (from 2008 to 2060) in the map by Patterson (2008) shows that the driest regions of the Earth such as Africa and the Middle East have a higher rate of growth. These regions also include those areas of Earth with moderate to severely degraded soils illustrated in the global soil degradation map. (SRIC 2002)
