Vertical Saltwater Intrusion in Coastal Aquifers Driven by Episodic Flooding: A Review

Water Resources Research, Год журнала: 2022, Номер 58(11)

Опубликована: Окт. 17, 2022

Abstract Low‐elevation coastal areas are increasingly vulnerable to seawater flooding as sea levels rise and the frequency intensity of large storms increase with climate change. Seawater can lead salinization fresh aquifers by vertical saltwater intrusion (SWI). Vertical SWI is often overlooked in zone threat assessments despite risk it poses critical freshwater resources salt‐intolerant ecosystems that sustain populations. This review synthesizes field modeling approaches for investigating practical theoretical understanding flushing processes obtained from prior studies. The synthesis explores complex dynamics influenced density‐dependent flow oceanic, hydrologic, geologic, climatic, anthropogenic forcings acting on across spatial temporal scales. Key knowledge gaps, management challenges, research opportunities identified help advance our vulnerability groundwater. Past studies focus idealized aquifer systems, thus future work could consider more diverse topographic environments. Concurrent programs should be sustained over time capture interactions between physical processes, repeated events, delayed responses. Finally, this highlights need improved coordination translation disciplines (e.g., engineering, hydrogeology, oceanography, social science) gain a holistic SWI. There also needs education communities, policy makers, managers motivate societal action address groundwater changing climate.

Priorities for protected area expansion so nations can meet their Kunming‐Montreal Global Biodiversity Framework commitments

Integrative Conservation, Год журнала: 2023, Номер 2(3), С. 140 - 155

Abstract As part of the Kunming‐Montreal Global Biodiversity Framework (K‐M GBF), signatory nations Convention on Biological Diversity (CBD) aim to protect at least 30% planet by 2030 (Target 3). This bold ambition has been widely celebrated and its implementation seen as pivotal for overall success K‐M GBF. However, given that many CBD prioritised quantity (e.g., area) over quality important areas biodiversity) when attempting meet their 2010 Aichi protected area commitments, it is critical focus protecting those terrestrial, inland waters marine have best chance halting reversing biodiversity loss thus contribute Goal A Here we provide a review type need prioritise implementing Target 3 relates ‘quality’: particular importance ecosystem functions services, are effectively conserved managed through ecologically representative, well‐connected equitably governed systems . We show data available 12 distinct conservation service elements can be mapped and, if conserved, will (with appropriate management) help broad intention 3. highlight examples planning methods utilized so these targeted protection. discuss issues related trade‐offs regarding how amongst them well operationalise some vaguer concepts like ‘representation’ ‘ecosystem services’ they achieve outcomes biodiversity.

Shoreline Dynamics of the Nile, Indus, and Yellow River Deltas: Analyzing Historical Changes and Influencing Factors

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Март 7, 2025

Deltas are dynamic systems that form rich, fertile, and densely populated areas. The Nile, Indus, Yellow River deltas historically culturally important have experienced severe erosion land loss over the last 50 years. However, causes of these losses were not always clear, especially role natural human factors in evolution deltas. To address this issue, we analyzed years satellite data (1972–2022) using Landsat imagery Digital Shoreline Analysis System (DSAS) to assess historical shoreline changes. Net Movement (NSM) End Point Rate (EPR) calculated accretion rates. results show Nile Delta lost around 27 km² first 25 (1972–1997), largely due reduced water sediment from dams. management practices, such as seawalls breakwaters, slowed retreat years, reducing only 3 km². We find Indus about 300 dam construction excessive consumption. In contrast, accreted 500 (1973–1996) but has approximately 200 since then. summery, three been heavily impacted by activities will continue lose population growth, climate change, sea level rise. These findings emphasize importance understanding impacts coastal practices.

A functional vulnerability framework for biodiversity conservation

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Сен. 1, 2022

Abstract Setting appropriate conservation strategies in a multi-threat world is challenging goal, especially because of natural complexity and budget limitations that prevent effective management all ecosystems. Safeguarding the most threatened ecosystems requires accurate integrative quantification their vulnerability functioning, particularly potential loss species trait diversity which imperils functioning. However, magnitude threats associated biological responses both have high uncertainties. Additionally, major difficulty recurrent lack reference conditions for fair operational measurement vulnerability. Here, we present functional framework incorporates uncertainty into generalizable tool. Through silico simulations disturbances, our allows us to quantify communities wide range threats. We demonstrate relevance operationality framework, its global, scalable quantitative comparability, through three case studies on marine fishes mammals. show has marked geographic temporal patterns. underline contrasting contributions richness redundancy level among studies, indicating assessment can also identify drivers where omnipresent.

Exploring Gender and Climate Change Nexus, and Empowering Women in the South Western Coastal Region of Bangladesh for Adaptation and Mitigation

This study has been conducted to identify vulnerabilities and effects of climate change on women in 12 unions Shyamnagar upazila the Satkhira district Southwestern Coastal Region Bangladesh (SWCRB). Climate vulnerability gender inequality may increase due change. Women may, thus, face specific conditions society daily livelihood. paper focuses investigating factors that influence women’s from change, their adaptations, importance empowerment reduce SWCRB. also emphasizes caused by looks at accommodations for hostile influences From 9 SWCRB, a total 320 household respondents were randomly selected complete questionnaire. The results statistical analysis showed most survey’s perimeter significant. Interviews, case studies, focus group discussions, workshops, key informant interviews unions, it was found impacts men differently, with being more vulnerable than men. Through this investigated main influencing women. In terms be well positioned lead adaptation efforts alongside men, as represent inequalities are leading social norms. both short-term i.e., major natural disasters, cyclones, flood, long-term sea level rise, salinity intrusion water soil, land erosion, droughts, climatic events, they enhance inequalities. Further, is seen illiteracy, food shortages poor health conditions, traditional norms, religious taboos, patriarchy. Moreover, gender-based economic opportunities, mobility, income changing, while authority relations socio-economic, cultural, institutional constraints remain. examines increased SWCRB which can mitigated through empowerment; female involvement environmentally friendly stoves, rural electrification renewable energy development, microfinancing, nakshikantha.
