Climate justice for the southwestern coastal region of Bangladesh

Abstract

Climate change is considered a moral, ethical and social issue, which makes it different from other developmental issues. The foremost instance of lack of justice regarding climate change is that the worst impacted areas are the ones with the lowest contribution to greenhouse gas emissions, such as the southwestern coastal region of Bangladesh (SWCRB). Climate change is principally triggered by the presence and eventual spread of industrialization. This study employed the mixed method, combining qualitative and quantitative methods of data collection and analysis for development of a framework for climate justice. Data and information were obtained from both primary and secondary sources. In primary sources, quantitative data were collected from climate vulnerable community households using a structured close ended questionnaire and interactive sessions such as focus group discussions, in-depth interviews, key informant interviews, workshops, and case studies. This study explored the perceptions of people in the SWCRB, currently experiencing devastating effects of climate change and sea level rise including extreme natural disasters, seasonal changes, flooding, salinization, riverbank erosion, and waterlogging. These climate-induced changes are causing loss of housing, livelihoods, and land to the natives, in addition to a lack of access to proper nutrition, potable water, and healthcare thus exacerbating social injustice. A capability-based approach to climate justice is introduced in this paper, which allows for residents of this region to prepare and rebuild their own communities and create adaptive mechanisms based on their specific capabilities. This approach requires compensation (funding) from the global community, in addition to organizational connection between local people and other stakeholders. The people in the SWCRB are increasingly opting for community-based disaster management and inclusion in policy making. Persistent issues faced by these communities require sustainable development of embankments and infrastructure, as well as affordable and sustainable access to potable water. Industrialized nations should provide this compensation for climate change, in addition to acting promptly to reduce greenhouse gas emissions and opt for renewable energy to avoid worst-case scenario. Lastly, involuntarily displaced climate refugees must be provided rights, compensation, and relocation assistance.

Metal-sulfide/polysulfide functionalized layered double hydroxides – recent progress in the removal of heavy metal ions and oxoanionic species from aqueous solutions

“…this issue is expected to escalate, affecting nearly six billion people globally. 2 Hence, the exponential increase in the water crisis is directly related to population and industrial growth. Heavy metals, such as cadmium, zinc, silver, lead, copper, and mercury, remain in wastewater, and their improper discharge severely contaminates ecosystems, posing risks to biological systems.…”

Atmospheric CH4 Dynamics of South-West Bangladesh: A Google Earth Engine-Based Remote Sensing Approach

“…In an important river in South-West Bangladesh, The Rupsha River metal concentration of As, Pb, Cd and Cr were found in sediment sample which attributed to natural sources and anthropogenic industrial activities (Tareq et al, 2022). Due to river erosion and new alluvial deposition the estuarine islands constantly change shape and position (Ashrafuzzaman et al, 2022a).…”

“…The impacts of SLR are worsened by floods, eroding coastlines, saltwater intrusion, increased storm frequency and ecosystem changes (Ashrafuzzaman et al, 2022b). The residents of the southwestern coastal region of Bangladesh (SWCRB) are trying to adapt to the effects of climate change and sea level rise (CCSLR) as saltwater intrusion, agricultural loss, and high-intensity cyclones (Ashrafuzzaman et al, 2022a) Eutrophication is the process of deposition of nutrients and minerals such as phosphate and nitrates. This phenomenon hinders aquaculture farmers by changing the biochemical oxygen demand (BOD) and transparency.…”
