one in every of the impacts that global climate change will have is to exacerbate the worldwide progression of desertification. alittle decrease in precipitation can destroy fertile land and might increase the extent of dryland area. although desertification isn't unaccustomed humanity and has long been existed however recent decades have seen acceleration in desertification.
Not solely deserts are increasing apace but desertification has additionally affected antecedently untouched and unaffected areas. geological process could be a problem that may be simply avoided by following property agricultural practices, but is not dropped at the general public attention till it reaches a vital point.
the subsequent facts replicate the realities of geological process today' world is facing:
Roughly 8.9 billion acres of the world' agricultural land has been degraded because of sick practices of agriculture.
Nearly 52,000 sq klick of agricultural land is destroyed by agriculture each year.
geological process leads to crop losses of nearly $42 billion per year.
because of desertification of land, a lot of farmers are forced to depart agriculture and appearance for alternative jobs.
geological process destroys the highest layer of productive soil and makes it terribly tough to grow crops and vegetation.
Deforestation and excessive use of pesticides and fertilizers are the main causes of geological process.
Population explosion and increasing placental pressure on the productive land are another reasons for desertification.
heating and global climate change acts sort of a catalyst in desertification through changes in natural cycles.
geological process has affected virtually 75% land in North America.
geological process plays a serious role in decreasing multifariousness through loss of natural habitats and ecosystems.
geological process Solutions: a way to avoid Desertification?
the most effective way to agitate geological process is to forestall it from happening within the initial place. This includes eco-friendly agricultural and grazing practices to be adopted, correct land management etcetera
the opposite property practices to stop desertification are:
Protection of vegetative cover.
Combining areas of farming and grazing.
Land and water management planning.
correct utilization of natural resources to limit stress on productive land.
Future Trend of Desertification:
in step with IPCC, several deserts can face a 5-15 p.c decrease in rainfall. A study conducted in 2006 reveals that Amazon rain forest may become deserts if the trend of worldwide warming still rise like this. If this happened, the billion loads of greenhouse gases unfree in these rainforests are going to be discharged into atmosphere and it'll any speed up the speed of global warming
