Integrating RUSLE Model with Cloud-Based Geospatial Analysis: A Google Earth Engine Approach for Soil Erosion Assessment in the Satluj Watershed

Water, Journal Year: 2024, Volume and Issue: 16(8), P. 1073 - 1073

Published: April 9, 2024

This study employed an advanced geospatial methodology using the Google Earth Engine (GEE) platform to assess soil erosion in Satluj Watershed thoroughly. To achieve this, Revised Universal Soil Loss Equation (RUSLE) model was integrated into study, which revealed through several analytical tiers, each with a unique function. The commenced estimating R factor, carried out annual precipitation data from Climate Hazards Group Infra-Red Precipitation Station (CHIRPS). erodibility of soil, K factor describes, then calculated USDA texture classifications taken Open Land Map. third layer emphasizes LS analyzes slope and how they affect rates, digital elevation models. understand impact vegetation on conservation, fourth presents C evaluates changes land cover, Normalized Difference Vegetation Index (NDVI) derived Sentinel-2 data. P incorporates MODIS types cover conditions. Combining these layers RUSLE produces thorough loss map, revealing different levels throughout Watershed. preliminary findings indicate that 3.3% watershed had slight loss, 0.2% moderate 1.2% high rates. And 92% severe rates erosion. After investigation, detected regions were divided risk classifications, providing vital information for watershed’s management conservation plans. mean determined be 10,740 tons/ha/year. novel method creates strong foundation evaluating erosion, while also highlighting value cloud-based analysis comprehending intricate environmental processes.

Silvopastoral systems have complex impacts on a diverse range of outcomes, making it essential to design these using an integrative approach maximise positive farms. This paper comprises firstly systematic review global silvopastoral processes, and secondly stakeholder-driven synthesis key opportunities challenges for future silvopastoralism situated in the context New Zealand. The demonstrated that although under-researched, livestock interactions can overriding influences system, traditional functional traits are typically deemed important selection (N2-fixing trees v non N2-fixing trees, evergreen deciduous) do not show consistent agroecological environment. From Zealand participatory case study, including stakeholder workshop, we synthesised 5 principles should be considered system designs. These were: (1) require holistic management; (2) views, values experiences local people deeply connected design; (3) spatial heterogeneity environmental social conditions requires locally specific decisions; (4) understanding ecological processes must underpin all management (5) complexity present high-resolution data tools.
