Cambios de uso de la tierra en la provincia de Morona Santiago periodo 2012-2020

Abstract

This study aims to evaluate the land-use changes in Morona Santiago province for the period 2012-2020, to estimate the possible consequence of land degradation problems. It was collected area data by hectares: forests, native, introduced and permanent crop, fallow, lie fallow and ranching provided by the public agriculture and livestock information system from 2012 to 2020; data was gathered in Microsoft Excel office and were created comparison charts of variations along that period and Pearson’s correlation procedures were followed to determine deforested areas, erosion, carbon dioxide emission and forests and pasture areas; it was determined temperature fluctuations and precipitations from the year 1980 to 2015. The results obtained in this study demonstrate that existed a forests surface replacements with pasture areas, which took to an erosion increase and a carbon dioxide emission, consequence of the expansion of stock during the years (2012) and (2013). It was identified that the following years from 2014 to 2020, conservation practices management such as fallow, lie fallow and reforestation reduced the erosion and carbon dioxide emission, which was connected to the changes in vegetation coverage. Throughout this study, it was identified that the land-use changes which foster the protection and conservation of the lands in Morona Santiago province, like coffee and cacao cultivation improve physical and chemical properties of the soil, so that it reduces erosion and global warming. It is recommended to create maps about the land-use changes in Morona Santiago province, including soil and hydrological factors.
