Historical Study of Land and Forest Degradation using GIS Technologies in Jaguay Negro – Lancones

The research entitled "HISTORICAL STUDY OF LAND AND FOREST DEGRADATION USING GIS TECHNOLOGIES IN JAGUAY NEGRO – LANCONES" assessed historical changes in forest cover and land degradation in this region. It used historical data, satellite imagery, and aerial photographs taken with drones, along with Geographic Information Systems (GIS), to analyze historical and current patterns of land use and vegetation cover. This methodology generated thematic maps and detailed spatial analyses. The results revealed a progressive decrease in vegetation between 2020 and 2024, with a notable increase in bare soils and sparse vegetation due to deforestation, water stress and unsustainable resource management. Critical areas with limited natural regeneration and greater loss of vegetation were identified. The study underscores the urgency of implementing reforestation, sustainable soil management and conservation strategies in priority areas. It also confirms the relevance of GIS and remote sensing as key tools for monitoring and managing resources in vulnerable rural contexts. In addition, this process strengthened forestry engineering students' skills in geospatial technologies, critical analysis of environmental data, and interpretation of results, preparing them to face complex challenges in the environmental field.
