Understanding the intricate relationship between climate variables and Normalized Difference Vegetation Index (NDVI) is essential for effective ecosystem management. This study focuses on spatiotemporal dynamics of NDVI its interaction with in ecologically diverse Khyber Pakhtunkhwa (KPK) Province, Pakistan, from 2000 to 2022. The research methodology involves analyzing satellite images meteorological datasets examine surface latent heat flux (SHF), total precipitation (TPP), temperature (T), soil (ST), pressure (TP). KPK Province's ecological significance complex climate-vegetation interactions drive selection this area. uses multiple linear regression analysis investigate how T, TPP, SHF, TP influence NDVI. Mann-Kendall test detects trends, Sen's slope estimator quantifying trend magnitudes. Additionally, correlation coefficients provide insights into long-term changes association strengths. findings highlight a consistent upward mean over 23 years, revealing an overall increase NDVI, particularly vegetation-dense areas where it rose 0.27 0.32. showed annual growth rate 0.84% entire area, specific vegetated zones exhibiting slightly lower 0.80%. However, average yearly higher vegetation-specific (0.00237) compared whole area (0.00151). occurs alongside statistically significant decrease SHF PPT, suggesting adaptation vegetation changing conditions Province. In contrast, exhibits negative −5.952e-06 (p < 0.05), indicating pronounced downward trend. Similarly, estimate demonstrates −0.0001 showing diminishing precipitation. uncovers linkages within These have far-reaching implications, guiding decision-making land management, conservation efforts, global resilience strategies. Ultimately, underscores critical role data-driven approaches shaping greener more sustainable future.

Assessing the existing guidelines of environmental impact assessment and mitigation measures for future hydropower projects in Pakistan

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 11

Published: Jan. 18, 2024

Introduction: More than 16% of the total electricity used worldwide is met by hydropower, having local to regional environmental consequences. With positive indicators that energy becoming more broadly available and sustainable, world moving closer achieving Sustainable Development Goal 7 (SDG 7). Pakistan became first nation include Goals (SDGs) in its national development strategy. Methodology: The current study sought investigate structural limits Environmental Impact Assessment (EIA) guidelines for hydropower Pakistan. included document review EIA reports about projects Pakistan, scientific questionnaires from decision-makers, public consultation. Results Discussion: evaluates an adequate mechanism available, donors like Asian Bank World observe implementation process However, a comprehensive analysis system found several things could be improved, not only institutional framework but also actual practices. 20% respondent decision-makers disagreed with compliance Institutional Framework guidelines, 25% think existing followed are aligned international standards practices Hydropower practice. has limited impact on decision-making due insufficient technical financial resources. Recommendations: There should tank experts who can meet needs present future epochs. communicated educated EIA. For better efficiency, officers trained internationally, i.e., Water Power Authority (WAPDA).
