This study investigates the relationship between vegetation dynamics and climatic variations in Pakistan from 2000 to 2023, using high-resolution Landsat data for NDVI analysis and climate data from CHIRPS and ERA5. The research combines statistical methods including linear regression, Mann–Kendall trend tests, Sen's slope estimator, partial correlation, and cross wavelet transform to analyze spatial and temporal variations in NDVI. The findings show an annual increase in NDVI of 0.00197 per year (p < 0.0001), accompanied by an increase in precipitation of 0.4801 mm/year (p = 0.0016), while temperature and solar radiation show slight decreases. Cross-wavelet analysis highlights significant coherence between NDVI and climatic factors, with precipitation as a primary driver of vegetation growth. The study reveals distinct seasonal patterns, with vegetation health most responsive during the monsoon season. The analysis underscores the complex association between vegetation health and climatic factors across different regions of Pakistan, emphasizing the critical influence of climatic drivers on vegetation patterns. These insights are crucial for developing climate adaptation strategies and sustainable agricultural and environmental management practices. The study also highlights regional variations in NDVI trends, with KPK showing a significant greening trend, while other regions exhibit varying degrees of vegetation change. The analysis of climatic variables shows that precipitation significantly impacts NDVI across all regions, while temperature has varying effects, with the most notable impacts observed in GB. Solar radiation has limited significant positive effects on NDVI, particularly in arid zones like BL. The study provides insights into the complex relationship between NDVI and climatic variables, highlighting the importance of precipitation in driving vegetation growth and the need for tailored environmental strategies to maintain ecological well-being.This study investigates the relationship between vegetation dynamics and climatic variations in Pakistan from 2000 to 2023, using high-resolution Landsat data for NDVI analysis and climate data from CHIRPS and ERA5.
