Executed a 25‑year vegetation change analysis for Sonadia Island using MODIS NDVI and non-parametric trend techniques to support coastal habitat conservation and land‑use planning.

• Processed MODIS MOD13Q1 in Earth Engine (2000–2024) into annual NDVI means, applied gap-filling, and masked to island boundaries for focused analysis.

• Conducted Mann–Kendall and Sen’s slope trend mapping at pixel level, quantifying significant greening (+0.007 NDVI/year, p < 0.001) and revealing contrasting greening/browning zones across coasts.

• Produced spatial products that highlight areas of degradation and improvement, directly supporting spatial prioritization for conservation, restoration, and coastal zone management.
