Desertification Essay

Decent Essays

It is widely recognized that desertification is a serious peril to dryland and semi-dryland environments, which cover approximately 40% of the global land surface and populate millions of humans. The global drylands face an innumerable amount of problems that present tough and perplexing research, management and policy challenges. Desertification is the degradation of grasslands, savannas, and woodlands to a more desert-like condition, with resulting decrease in plant production and the land's ability to support livestock grazing or other human uses. (United Nations et al. 2006) The focus of this paper is to identify the causes and effects of desertification and assess how we can use plants to reduce desertification and to provide a …show more content…

Several potential solutions to combat against desertification may include initiatives such as a) education in teaching sustainable practices helping farmers/residents to understand how to best use the land, b) technology advancements using research and awareness in finding new and improved methods towards prevention c) policy changes relating to how people can farm and how types of lands are governed and d) rehabilitation efforts to restore the land that has already been affected. The focus on global drylands is shifting from an emphasis on negative images of desertification to a more forward-looking perspective concerning human livelihoods, based on interactions between and among human activities and natural-world processes. (Reynolds et al. 2007) The Drylands Development Paradigm represents a convergence of insights and key advances drawn from a diverse array of research in desertification, vulnerability, poverty alleviation, and community development. (Reynolds et al. 2007)

A new model has been introduced which includes a set of strategies that has been developed to reduce soil erosion by planting vegetation in desertification hotspots. The model reproduces a wide range of patterns observed in water-limited regions, including drifting bands, spots, and labyrinths. It predicts transitions from bare soil at low precipitation to homogeneous vegetation at high precipitation, through intermediate states of spot, stripe and hole
