Desertification: threat to agricultural land.
Mayors of Mexico magazine. Posted By Editorial. August 12, 2016 Mexico.
Degradation and desertification of Mexican agricultural land is a problem that threatens about 80 percent of the field. At the government level it seek to identify policies at local and regional levels that reduce erosion involving all levels of society, through alternative sustainability and reduced excessive water use techniques. areas vulnerable to human activity land and excessive use of agricultural pesticides and heavy machinery being degraded areas that are not necessarily in desert conditions are identified. Institutions attack areas that still have weak deforestation and desertification and sustainable management can stand there to promote the use of special machinery and technology, with the implementation of rescue strategies.
Degradation and desertification of Mexican agricultural land is a problem that threatens about 80 percent of the fields and involves, among its consequences, poor food generation, said the head of the research group Climate Change and Biodiversity of the Faculty Philosophy and Letters of the National Autonomous University of Mexico (UNAM), Leticia Gómez Mendoza.
“Desertification and land degradation is defined as all the changes that happen in the land associated conditions weather, but also due to consequences of the lack of sustainable use of agricultural land around the world,” said the researcher in an interview with the News Agency Conacyt.
In this context, many countries saw the need to address this serious problem and it created the United Nations Convention to Combat Desertification (UNCCD), which is the body responsible for organizing international cooperation to combat this problem. The consequences of this process are a negative impact on agricultural land. The causes of desertification can be by overgrazing and deforestation that triggers a process of wind erosion and increases energy returning from the atmosphere, thus increasing the temperature of the earth. A very severe condition of desertification seen in creating a crust on the soil surface preventing water seepage.
The UNCCD seeks to form agreements among nations to combat effects of climate change, for this action for the sustainable use of water resources are promoted, and also seek to promote organic agriculture and the use of alternative energy for cultivation and agricultural production. It is looking for people who work on the land for their livelihoods involved in promoting sustainable techniques climate-smart for agriculture crops to adapt to climate variability.
In Mexico, institutions such as the National Water Commission (Conagua), with the National Program Against Drought (Pronacose) and the Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA), through the National Commission Arid Zone (CONAZA), are those who create prevention programs and research about desertification.
A government level is to identify policies that reduce local erosion involving all levels of society. “CONAZA, for example, by alternative techniques sustainability and reduction of excessive water use, as some drip irrigation techniques, installing rows to prevent erosion or introduce some that are commensurate with the precipitation conditions reduced crop. The involvement of people in sustainable agricultural development is essential to creating productive long-range projects and high impact at local and regional level. Still a lot of work on the awareness of people and certain techniques can be applied.
The task in the country, is to identify land areas that are vulnerable by human factors such as excessive use of agricultural pesticides and heavy machinery being degraded areas that are not necessarily in desert conditions. Institutions attack areas that still have weak deforestation and desertification and sustainable management can stand there to promote the use of special machinery and technology as well as the implementation of rescue strategies that have to do with the different techniques.
CONAZA currently runs more than a thousand headworks and water storage reservoirs such as dams and micro. In previous years 687 works representing a storage capacity of 12.7 million cubic meters of water that are used, among other things, for strategies to combat desertification in agricultural areas.
“It is important to improve mechanisms for prevention from local and regional scales, and make use of weather forecasts in advance to prevent these conditions desertification. Understanding the climate condition to develop strategies to reduce losses in agriculture, “said Dr. Leticia Gómez Mendoza to the News Agency Conacyt
