Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled.
Agriculture influences and shapes the world’s ecosystems, but not always in a positive way. More than 2.5 billion people are globally involved as stewards of land and water ecosystems that constitute the natural resource base for feeding the current and future world population.
As of 2017, SGP has awarded over 3,800 small grants to land degradation projects in over 120 countries, many of which are in regions with extreme levels of poverty and food insecurity across Africa and Latin America.
Soil erosion is a global environmental problem and a pervasive form of land degradation that threatens land productivity and food and water security. Some of the biggest sources of sediment in catchments are cultivated and abandoned lands.
Land degradation is a major risk to the sustainability and functioning of socioecological systems (SES), especially in arid/semiarid regions. By understanding a system and its interlinkages, the socioecological approach offers an innovative way to explore degradation.
Understanding the interactions of the social and biophysical drivers of land degradation is crucial for developing adaptive management actions for future sustainability.
Although changes in ecosystems in response to climate and land-use change are known to have implications for the provision of different environmental and ecosystem services, quantifying the economic value of some of these services can be problematic and has not been widely attempted.
Environmental safety is one of the top policy priorities in some developing countries. This study analyzed the factors influencing waste disposal and recycling by households in South Africa. The data were collected by Statistics South Africa in 2012 during the General Household Survey (GHS).
