Impact Assessment of Land Use and Land Cover Change of Agusan River Basin to Climate Using Geospatial Techniques And Regression Analysis

Abstract

This study utilizes Geospatial Techniques and Regression Analysis to examine the impact of Land Use and Land Cover changes on the climate dynamics of the Agusan River Basin. It analyzes the correlation between Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) over a 20-year period from 2000 to 2020 with four (4) years interval. The study reveals a gradual negative trend in the LST-NDVI correlation, with notable spikes in 2004 and 2008, influenced by extreme temperature conditions linked to drought and El Niño. However, the trend increased in the years following 2012. The dominant land cover types in the basin are vegetation, barren land, built-up areas, and water bodies. This study contributes to a better understanding of the relationship between land use and land cover, and climate dynamics, aiding informed decision-making for sustainable land management and climate change adaptation strategies in the Agusan River Basin.
