Assessment Of Land Use And Land Cover Change Impact On Land Surface Temperature In Metehara City, Ethiopia

Abstract

This Study Investigates The Land Use Land Cover Change (LULC) Patterns And Their Consequences For Local Climate Dynamics In Metehara City, Ethiopia, From 1999 To 2020. Using Multi-Temporal Landsat Satellite Images and Advanced Remote Sensing and GIS Techniques, The Study Reveals Significant Shifts in Land Cover Classes and Their Impacts on Land Surface Temperature (LST).Key Findings Indicate That the Built-Up Area Expanded Significantly, Growing From 35.97Hectares in 1999 To 149.7 Hectares In 2010, And Further To 202.21 Hectares By 2020. Conversely, Other Land Classes, Including Agricultural Areas, Exhibited Varied Trends, With Notable Expansions And Contractions Over The Study Period. The Study Recorded LST Ranges Of 24.24??CTO 32.95??C In 1999, 30.01??C To 38.387??C In 2010, and 22.4049??C To 39.39??C In 2020. A Progressive Increase In Mean Temperatures Was Observed, With A Mean Difference Of 0.77??C Between 1999 and 2010, 0.75??C Between 2010 and 2020, And an Overall Increase of 1.52??C From 1999 to 2020. Maximum Temperatures Recorded Were 32.95??C, 38.887??C, And 39.4049??C For the Respective Years. Detailed Analysis of Agricultural Zones Highlighted Significant Temperature Fluctuations: From 128.16 Hectares with A Mean Temperature of 31.35??C In 1999, To 144.66 Hectares with 36.53??C In 2010, And Reducing To 113.85 Hectares with 36.12??C In 2020. These Changes Underscore The Influence Of Active Land Surface Heating From Agricultural Activities On Regional Temperatures. The Study Also Found A Negative Correlation between LST and Both the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI), And A Positive Correlation Between LST And The Normalized Difference Built-Up Index (NDBI).
