The 55.4 percent land area of Mexico is eroded by water factors such as rain, hail, flooding from rivers or the effect of irrigation, as well as wind causes such as swirls, tornado and due to the action of the man who changed the landscape abrupt and irreversible with road construction, urban settlements, pipelines, transmission lines and dams so. The greatest damage was caused by water erosion in the form of stream, which has damaged one million 27 thousand 612 square kilometers, accounting for 52.9 percent of Mexico. It is important to increase public policy attention to the ground in its adaptation to climate change and food security and resource mobilization for sustainable management.
The 55.39 percent land area of Mexico is eroded, mainly by factors such as rain water, hail, flooding from rivers or the effect of irrigation. Is also due to causes such as wind swirls, tornado and the man who changed the landscape abruptly and irreversibly with the construction of roads, urban settlements, pipelines, transmission lines and dams, among others, said the National Institute of Statistics and Geography (INEGI).
Erosion is the wear that occurs on the surface of the earth from external agents such as water erosion, wind erosion and accelerated by human activity (anthropogenic erosion). Overall, Mexico has one million 76 thousand 778 square kilometers affected by some erosion and there are four thousand 934 in extreme erosion”, ie, 0.25 percent of the total area. According to the institute, the soil erosion in Mexico for man only affects 0.12 percent of the national territory, equal to two thousand 388 square kilometers and wind erosion covers 46 thousand 779 square kilometers or 2.4 percent of total . Instead, water erosion caused by water but as stream damaged one million 27 thousand 612 square kilometers or 52.86 per cent of Mexico.
By degrees of erosion, is that almost a third of the country’s surface has a slight erosion, ie 608 thousand 791 square kilometers, equivalent to 31.32 percent of the total. Another 18 percent of the land has moderate erosion, 3.12 percent recorded another strong erosion and extreme erosion 0.25 percent. It can be in sheet form (47.51 percent of the total), Furrow, dust devils, mounds, dunes and gullies.
This year, to mark the World Day to Combat Desertification and Drought, held on June 17 and the United Nations established in 1994 launched the slogan “The land belongs to the future: keep of climate change “.
The UN set goals to increase its members in public policy attention to the ground in its adaptation to climate change and its importance in food security and mobilize resources for their sustainable management.
