Abstract
The central proposition of this article is to understand and discuss the situation generated by the constant droughts that plague the agricultural economy of several regions in Rio Grande do Sul in recent decades, especially with the adoption of degrading and polluting productive models since the 1970s. Also discuss some information about the natural phenomena that intensify the constant droughts, as well as the human action in the worsening of droughts. For this, we conducted a wide bibliographic research and interviews with researchers in the area. From this, it was identified that agroecology as a model of sustainable agriculture is an alternative to replace the dependent and degrading model of ecosystems in the production of food for gaúchos and for export. Also, with this sustainable model of production in agroecosystems, it is possible to guarantee environmental, economic and social improvements to the families of farmers from all agricultural regions, in addition to mitigating the constant droughts and droughts that have become frequent in recent decades, causing very large economic and environmental losses for all the production of Rio Grande do Sul.
Highlights
In recent years the theme of significant climate change has gained emphasis around the world
Researchers from several countries have come to a close, where some presented a conformist view that changes are natural and others counter, with very strong arguments, that climate change is caused by the uncontrolled action of man and capital over nature
Factors are listed by several researchers as promoters of the annual temperature increase and that cause constant climate change across the globe. Understanding these climate changes and observing their possible relationships with the constant droughts and droughts in southern Brazil is the objective of this work
Summary
In recent years the theme of significant climate change has gained emphasis around the world. Factors are listed by several researchers as promoters of the annual temperature increase and that cause constant climate change across the globe. Understanding these climate changes and observing their possible relationships with the constant droughts and droughts in southern Brazil is the objective of this work. In the development of this work, we sought the identification of papers, articles and publications that discussed this theme and could contribute to identify the relationship between the agricultural-climate-climate-drought-alternative model of sustainable production in order to contribute scientifically to this problem. Several interviews were conducted with researchers from different areas, farmers and technicians in order to better understand this theme and identify possible alternatives to mitigate climate change
