Vulnerability and effectiveness of nature-based solutions (NbS) in the farming communities of coastal Bangladesh

This study assesses the vulnerability of farming communities and the role of nature-based solutions (NbS) in reducing these vulnerabilities. In Bangladesh, coastal communities are highly vulnerable to the effects of climate change, affecting their farming practices and well-being. Thus, this study investigates farmers’ perception of ecosystem vulnerability, socio-economic vulnerability to climate change and the NbS adapted. For this, data were collected through in-depth interviews of about twenty-four farmers (equal ratio of male and female farmers) in Barishal, Bangladesh. The data were analyzed by content analysis method. We found that several factors including increased temperature, income shock, physical and mental health issues, and increased farmers' vulnerability to climate change. NbS can be effective in addressing those vulnerabilities. It can reduce the socio-economic vulnerability features, ecosystem, and impacts of NbS on farmers and agricultural land. It also highlights how the farmers perceive the vulnerability of the socio-ecological system of agriculture. NbS approaches have reduced salinity in the area due to the practice of NbS, improved the livelihood of farmers, enhanced soil fertility, and increased crop production, and community engagement. NbS strategies are implemented in both individual and collaborative methods. Our study implies that adopting NbS in farming practices can help address climate vulnerabilities, positively impacting local livelihoods, community health, and agricultural sustainability, thereby offering a context-specific strategy for resilience in the face of climate change

Mesoporous carbon supported MgO for CO2 capture and separation of CO2/N-2

Mesoporous carbon derived from pongamia pinnata fruit hulls was used as support to incorporate magnesium oxide for the study of CO2 adsorption and separation of CO2/N-2. All synthesized adsorbents were characterized by PXRD, N-2 adsorption-desorption isotherms, Raman and SEM with EDX techniques. Characterization results revealed the existence of magnesium oxide on mesoporous carbon. CO2 adsorption on MgO incorporated mesoporous carbon was higher than bulk mesoporous carbon, due to the electrostatic interaction between magnesium oxide and CO2. High CO2 adsorption capacity 1.68 mmol/g was obtained for 10 wt% MgO incorporated mesoporous carbon at 298 K, 1 bar compared to remaining loadings, because of the high content of MgO. However, the N-2 adsorption capacity decreased with the increase of MgO content due to a decrease in surface area and no interaction of the N-2 molecule with the adsorbent. The selectivity of CO2/N-2 was higher on 10 wt% MgO incorporated mesoporous carbon and the value was 40. The heat of CO2 adsorption was 36KJ/mol at low coverage of CO2, and CO2 adsorption capacity was constant in each adsorption cycle over the same adsorbent
