This study focuses on investigating the impact of climate change availability safe drinking water and human health in Southwest Coastal Region Bangladesh (SWCRB). Additionally, it explores local adaptation approaches aimed at addressing these challenges. The research employed a combination qualitative quantitative methods to gather data. Qualitative data were collected through various means such as case studies, workshops, focus group discussions (FGDs), interviews, key informant interviews (KIIs). specifically from 12 unions Shyamnagar Upazila.

Abstract Urbanisation and population growth are concentrated on the coast with approximately 40% of human living within 100 km ocean. The freshwater systems which coastal urban areas rely vulnerable to bidirectional pressures including processes such as sea-level rise erosion coupled land use changes pollution occurring in inland catchment areas. These threats likely be amplified future under climate change conditions more frequent severe drought periods expected jeopardise already constrained water supply systems. Groundwater is used a resource globally especially important conjunctive during due perceived buffer capabilities. However, several impact aquifers over-abstraction, salinisation, subsidence groundwater flooding often these subterranean resources “out sight out mind” when it comes management strategies. Here, we present an assessment current issues options relevant using recent literature. insights provide knowledge global resources, regarding droughts.

Climate change and human security in coastal regions

Cambridge Prisms Coastal Futures, Год журнала: 2024, Номер 2

Опубликована: Янв. 1, 2024

Abstract Climate change has been recognised as a major concern in coastal hotspots exposed to multiple climate hazards under regionally specific characteristics of vulnerability. We review the emerging research and current trends academic literature on risk adaptation from human security perspective. The ecological socioeconomic developments are analysed for key areas, including infrastructure; water, food fisheries; health; mobility; conflict, taking different geographical contexts areas islands, megacities deltas into consideration. Compounding cascading interactions require integrative policy approaches address growing complexity. Governance mechanisms focus management adaptation, nature-based solutions community-based considering their synergies trade-offs. This perspective allows holistic view risks vicious circles societal instability systems interconnectedness dimensions necessary sustainable transformative most affected hotspots.

Decision support system for community managed rainwater harvesting: A case study in the salinity-prone coastal region of Bangladesh

Heliyon, Год журнала: 2024, Номер 10(9), С. e30455 - e30455

Опубликована: Май 1, 2024

Climate change-induced saline intrusion into both surface and groundwater, extreme weather events, unregulated water usage are serious threats to the drinking supply in coastal areas worldwide, especially least-developed countries. This research developed a data-driven decision-making methodology evaluate performance of rainwater harvesting (RWH) systems saline-prone southwestern region Bangladesh. Twenty-five community managed RWH systems, recently piloted two major districts, were considered case study develop validate this evaluation tool. The integrates daily models, lifetime cost analysis, Geographic Information System (GIS)-based parameters supported by Analytical Hierarchy Process (AHP), field observation. While meteorological as well hydrological economic found be highly suitable, 36% showed moderate performance, challenges remain ensuring proper operation maintenance practices at level. However, 40% high with showing very suitability, which suggests sustainable adaptation for supply.
