The findings revealed that climate-related incidents in Bangladesh forced people to move from vulnerable to less vulnerable areas. People who have been hurt by disasters often decided early on to move away in search of a better life. Although many disaster-affected people had the minimum opportunity to stay in the same places, they migrated to avoid future risks and search for a secure life. Migrants faced many socio-economic and environmental challenges in their new settlements. The raising awareness and policy strategies regarding environmental pollution and climate adaptation are urgently needed to reduce the hazard risks and vulnerability of the communities.</p></div>","PeriodicalId":34472,"journal":{"name":"Current Research in Environmental Sustainability","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666049024000136/pdfft?md5=15fd9825208bc33a3e3b9c5d4807c2b2&pid=1-s2.0-S2666049024000136-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140330588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings highlight several key factors significantly impacting technology adoption, including education, caste, employment status, household income, orchard ownership, landholding size, irrigation source, access to irrigation, the Kisan Credit Card scheme, and utilization of electric and diesel pumps. Moreover, the study uncovers state-specific variations driven by factors such as water resources, crop patterns, and government policies, ultimately shaping the adoption landscape of specific irrigation technologies. Focus group discussions conducted in Andhra Pradesh reveal prominent challenges faced, including limited subsidies, high costs associated with adoption, and crop-specific irrigation requirements. In light of these findings, the study emphasizes the necessity for a comprehensive approach to achieve water conservation and enhance livelihoods. This approach advocates for the integration of joint farming practices, water-sharing methods, supportive financial policies encompassing subsidies and accessible credit facilities, and the implementation of sustainable government social schemes.

First, we discuss the measurement of environmental concern and construct a ranking of countries according to the 2020 survey results. Second, we analyze the determinants of environmental concern by employing multilevel models that take individual effects as well as context effects into account. The results show that environmental concern has increased in almost all nations since the last measurement in 2010. The country ranking is headed by European nations such as Switzerland, France and Germany. The USA takes a middle position and China ranks number 20. We observe more variance within countries at the individual level as compared to the differences between countries. At the individual level, environmental concern is closely related to education, post-materialistic values, political attitudes, and individuals' trust in the news media and in science.

While innovations such as index insurance and bundled financial instruments could enhance smallholder farmers' climate resilience, their uptake, and use remain low, especially among women farmers. Based on experimental data from a risk contingent credit (RCC—an insurance bundled credit product) project in Kenya, we argue that employing inclusive extension approaches that address social inequities in information access and use could enhance gender equality in product understanding, a key determinant of uptake. We evaluate the gender differences of the impacts of conventional face-to-face, animated brochures, and video-based extension approaches on product understanding and willingness to pay (WTP) for RCC. We find that; (i) providing animated brochures to a random subset of farmers significantly improved their understanding and WTP for the product, (ii) the use of animated videos significantly increased product understanding, but it had weaker impacts on the farmers' WTP, and (iii) the impact of animated brochures on product understanding was significantly larger among women farmers. This study underscores the importance of addressing social and cultural barriers to agricultural information access and use, and designing tailored extension approaches to support men and women in making informed decisions about climate risk management. From a policy perspective, we conclude that addressing these barriers could foster a socially fair, and a more sustainable and resilient agricultural sector for both men and women smallholder farmers.</div></div>","PeriodicalId":34472,"journal":{"name":"Current Research in Environmental Sustainability","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Employing statistical mechanics methods to scrutinize Hamiltonian system costs related to administrative interactions for water supply-demand, the study assessed the structural fit of the water governance system to the basin across distinct stages: without- and with-including the ULRP.

Employing a counterfactual approach, we gathered survey responses from 459 small-scale farming, agro-pastoral, and artisanal-fisheries-based households. The survey provided information on general household characteristics, land use, land management, livelihoods, well-being, and any perceived changes to these variables, as well as any perceived mining impacts related to the changes. Overall, respondents reported predominantly negative effects on land (and sea) use, livelihoods, well-being, and security. Mining pollution, primarily from operational sites, had reduced access to water and fisheries resources, and natural forest areas had diminished. Reduced productivity due to pollution of soils, water, and air had a negative impact on various land uses and affected people's health, particularly in the surroundings of QIT Madagascar Minerals/Rio Tinto. Although some projects, such as Ambatovy, had eventually improved healthcare and infrastructure, most negative mining impacts had occurred during both the exploratory and the operational phases of the projects. Overall, this study offers a comprehensive view of how large-scale extractive investments affect land (and sea) use and human well-being.

Equitable water governance is conceptualized as formal and informal polycentric decision-making that narrows infrastructure inequities and ensures equitable water resources allocation. Focusing on recognitional and procedural equity, vulnerable women's and men's community-based water tenure is starting point. Partnering with government in Zambia and with the Water Integrity Network in Kenya, field research in three communities in rural Zambia and in rural communities and a small town sharing several schemes in Kenya is conducted. These studies <em>recognized</em> horizontal polycentricity of community-based water tenure by identifying common features: communities' age-old drought resilience coping strategies to meet daily domestic water needs and daily or seasonal small-scale productive water needs, by tapping water from surface- and groundwater sources through multi-purpose infrastructure, both self-financed and publicly supported, and by ‘sharing’ water ‘in’ within the community and ‘sharing out’ with neighbouring communities and powerful third parties. <em>Procedural</em> equity implies inclusive, locally-led planning, design and implementation in polycentric vertical governance with governments and other support agencies from local to national level and vice versa.
