Soil erosion is a major environmental threat to the sustainability and productive capacity of agriculture. During the last 40 years, nearly one-third of the world's arable land has been lost by erosion and continues to be lost at a rate of more than 10 million hectares per year. With the addition of a quarter of a million people each day, the world population's food demand is increasing at a time when per capita food productivity is beginning to decline. 
Ecology of Soil Erosion in Ecosystems
ABSTRACT Each year, about 75 billion tons of soil are eroded from the world's terrestrial ecosystems. Most agricultural land in the world is losing soil at rates ranging from 13 tons/ha/year to 40
Soil Degradation: A Challenge to Sustainable Agriculture
Agricultural practices have a substantial impact on many ecosystems worldwide, and give rise to variety of ecological problems. Soil degradation is one the key areas in which agriculture impacts upon
Soil Erosion: A Food and Environmental Threat
Soil erosion is one of the most serious environmental and public health problems facing human society. Humans obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the
Water Erosion in Oxisols under Coffee Cultivation
ABSTRACT Water erosion is one of the main environmental impacts of land use. When soil and water losses occur, nutrients essential for the growth and maintenance of plants are removed, with harmful
Soil-erosion and runoff prevention by plant covers. A review
– Soil erosion is a critical environmental problem throughout the world’s terrestrial ecosystems. Erosion inflicts multiple, serious damages in managed ecosystems such as crops, pastures, or forests
Sustainable soil and water resources: modelling soil erosion and its impact on the environment
With the projected increase in world population to 9 billion by 2050, along with per capita income growth, the demand for land and water resources is going to increase significantly. Conversion of
