This investigation addresses this gap by examining how groundwater recharge variability, influenced by these environmental changes, affects aquifer vulnerability to contaminants. An integrated GIS-based DRASTIC model approach incorporating well logs, precipitation records, geological maps, and land use data assessed and mapped climate-LULC interactions on vulnerability zones across the basins. Results demonstrate significant spatiotemporal variability, with 32 % of the area classified as moderately vulnerable, while high (23 %) and very high (17 %) vulnerability zones concentrate predominantly in the Ankobra Basin, particularly near mining towns like Prestea, Tarkwa, and Bibiani. Model validation confirmed high reliability (85 % accuracy, Kappa = 0.65), with projections indicating a transition toward lower vulnerability under future scenarios. Very low vulnerability areas may expand across all periods (near, mid, and far future), while high and very high zones could decline by 9.58 % and 11.93 % respectively by the far future. The findings highlight the need for targeted strategies in mining-affected areas, including stricter environmental regulations, groundwater protection zones, and sustainable land management. Integrating continuous monitoring with adaptive approaches, such as artificial recharge systems and climate-informed land use planning, can enhance groundwater resilience. This study provides policymakers and water managers with actionable insights to develop robust protection measures, offering a transferable framework for vulnerable basins facing similar climatic and anthropogenic stresses. Science-based monitoring and multi-stakeholder collaboration emerge as critical components for safeguarding groundwater resources under changing environmental conditions.</div></div>","PeriodicalId":101280,"journal":{"name":"Watershed Ecology and the Environment","volume":"7 ","pages":"Pages 208-229"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After 2003, significant changes occurred in the “river-lake relationship” between Poyang Lake and the Yangtze River, with intensified dry conditions in autumn and winter leading to a shortened inundation period for sandbanks and significant changes in the community structure and spatial distribution of wetland vegetation. By coupling a Gaussian model with a population dynamics model, this study simulated the response of wetland vegetation to inundation duration under different hydrological year types, revealing the relationship between vegetation distribution and inundation duration. Key parameters, such as growth and mortality rates, were identified, and the vegetation succession and spatial distribution of Poyang Lake wetlands were simulated for five representative years: a wet year (2010), a normal year (2001), a dry year (2006), an extreme wet year (1998), and an extreme dry year (2022). The results showed that the response of wetland vegetation to inundation duration followed a Gaussian curve, with each species exhibiting an optimal range of inundation durations. Mortality rates increased when the duration fell outside this range. In 2010, the total area of wetland vegetation was similar to that in a normal year, but the proportions of different plant species varied significantly.

Roadside curb inlets are key components of grey infrastructure that convey stormwater to various drainage systems. Curb inlets for conventional drainage systems are typically long, whereas they are usually shorter for directing stormwater to sustainable green stormwater infrastructures (GSIs), such as a roadside bioretention cell. As shorter curb inlets drain stormwater to GSIs, they have noteworthy advantages over conventional inlets such as environmental sustainability, urban flood resilience, pollution control, improved public health, and mitigating urban heat stress. This perspective aims to present a global outlook on the implementation of sustainable GSI curb inlets while also exploring the transition from conventional to sustainable systems. While some countries such as the USA, Canada, and China have adopted sustainable drainage practices including curb inlets, most regions, such as South Asia, Central America, and Africa are still far from embracing these practices. For the wider implementation of sustainable curb inlets with GSIs, recommendations include framing policies at the ministry level, raising awareness through research institutes, and educating the public on the benefits of sustainable drainage.

Pearson’s correlation matrix (PCM) analysis revealed a significant negative correlation between surface OC and both salinity and pH (p &lt; 0.05).

Furthermore, there is a lack of previous analysis on determining the integrated watershed management model (IWMM). Therefore, this study aims to define the level of soil quality and land capability classes (LCC) as well as construct appropriate IWMM through SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis and AHP (Analytical Hierarchy Process) method.

The indicators determining SQI included in MDS are Ca, organic C, pH H2O, and base saturation, respectively.
