Deforestation analysis using geographic information systems in the Juninguillo - Moyobamba - San Martin micro-watershed. Vegetation cover plays a fundamental role in terrestrial ecosystems because it provides different ecosystem services for the benefit of populations; however, in recent years, anthropic activities have caused the loss of large areas of forest cover in the different micro-watersheds of the world, a problem that is not unknown in the Juninguillo micro-watershed. The general objective was "To carry out an analysis of deforestation using Geographic Information Systems in the Juninguillo - Moyobamba micro-watershed". The research project was developed in the Juninguillo micro-watershed of 3,292.08 ha, located in the district and province of Moyobamba, department of San Martin. The execution period was 8 months (from 10/07/2021 to 15/03/2022). The population and sample consisted of 3,292.08 ha. It was a basic and descriptive type of research, with a simple descriptive research design. Landsat 5 and 8 (2008 and 2014) and Sentinel 2 (2020) satellite images were identified and selected, processed, corrected atmospherically and geometrically, classified and then thematic maps were prepared using geographic information systems. The unsupervised and supervised classification was also developed to determine vegetation cover and land use, and finally, an alternative was proposed to recover the deforested areas in the micro-watershed. ArcGIS software and descriptive statistics were used to process and analyze the results through tables and figures with SPSS Statistics software. It was determined that between 2008 and 2020 the deforested area increased by 31.93% (1,051.25 ha), being greater in the period from 2014 to 2020 with an increase of 21.48% (707.05 ha) unlike the first period between 2008 and 2014 where the deforested area only increased by 10.46% (344.20 ha) of the total area of the micro-watershed. In addition, 5 vegetation coverages were determined, the most representative being the sub-Andean mountain forests with medium-sized trees and dense scrubland, and 4 land uses were determined, with the area without productive use as the most representative. Finally, the implementation and execution of a reforestation and conservation plan for the forests of the Juninguillo micro-watershed was proposed, with the planting of 400 seedlings per hectare of characteristic trees of the area, with an investment of S/. 9560.00 per hectare. It was concluded that the geographic information systems allowed to determine that during the period 2008 to 2020, the deforested area increased at a rate of 87.6 ha/year.
