Descripción
Monitoring forests is key to ensure sustainable natural resources conservation. Land cover has been the most widely used product to measure how forests has been changing. Zimbabwe first produced its national land cover map in 1992 and it has been used as the basis for forest resources monitoring. Given the power of Google earth engine, in 2017 another land cover map was produced. The twenty-five years of forest monitoring has shown a remarkable decrease in forest area due to mainly agriculture expansion. Sharing of land cover information has evolved over the years from paper based to digital platform. The Google earth engine app was produced from 2017 land cover map and it has increased the wide use of forest information and data. The change between 1992 and 2017 was obtained after subtracting the two maps. The forest loss was then analysed using Collect earth online, a total 3500 plots were analysed using high resolution satellite imagery.
