Short Summary

This study analyzes how soil salinization and groundwater levels impact vegetation cover in irrigated agroecosystems, finding that high groundwater levels increase soil salinity and deteriorate vegetation with a 3–4 month delay.

Objective

• To analyze the impact of soil salinization and groundwater levels on vegetation cover in irrigated agroecosystems using GIS technologies and vegetation indices.

Study Configuration

• Spatial Scale: Irrigated agroecosystems (regional/local scale).
• Temporal Scale: Multi-month to annual scale, with observed time-lags of approximately 3–4 months.

Methodology and Data

• Models used: NDVI (Normalized Difference Vegetation Index), SAVI (Soil Adjusted Vegetation Index), IDW (Inverse Distance Weighting) interpolation, Kriging interpolation, Moran’s I spatial autocorrelation index, spatio-temporal regression, time-lag techniques.
• Data sources: Multispectral satellite imagery (Landsat 8–9, Sentinel-2), in-situ data on soil salinity, in-situ data on groundwater levels.

Main Results

• Areas characterized by high groundwater levels consistently exhibit increased soil salinity, which subsequently leads to a deterioration of vegetation cover.
• Changes in groundwater levels impact both soil salinity and vegetation indicators with an average time delay of approximately 3–4 months.

Contributions

• Demonstrates the utility of spatio-temporal monitoring, integrating GIS and vegetation indices, as a crucial analytical tool for the scientific planning of land reclamation measures in irrigated agroecosystems.
• Provides a framework to promote rational resource use and ensure the sustainability of agroecosystems through improved understanding of hydro-salinity-vegetation interactions.
