Assessing spatial vulnerability of Bangladesh to climate change and extremes: a geographic information system approach

Wide-ranging impacts of a changing climate are already being documented in many parts of Bangladesh, recognized globally as one of the most susceptible countries to the influences of climate change. Bangladesh's water sector infrastructures are expected to experience substantial damages due to more frequent and/or more intense floods and extreme weather events. Particularly, the southern portion of the country faces severe risk due to climate change induced susceptibility and various socioeconomic and environmental barriers that are hindering sustainable adaptation. The primary goal of this review is to produce a comprehensive study on climate change impacts, mitigation, and adaptation in the water sector in Bangladesh. In the past, numerous researchers have studied climate change impacts, mitigation, and adaptation strategies in Bangladesh; however, comparatively few studies attempted to determine the overall efficacy of adaptation measures implemented at the local and national levels. This paper is the outcome of a systematic review of relevant scholarly and nonscholarly materials, and it offers a deeper insight into Bangladesh's climate change mitigation and adaptation strategies.

High temperatures and heatwaves are becoming more frequent, but heat vulnerability is rarely considered within local authority city design and statutory land-use planning processes. Here, we describe an approach to assess heat vulnerability in Birmingham, the second largest city in the UK. The approach uses open access data and GIS techniques that are available for built environment practitioners. Heat vulnerability is assessed by combining four datasets: surface temperatures, Local Climate Zones, green space, and Indices of Multiple Deprivation. The assessment shows that central and eastern areas of Birmingham that have the most compact urban form, least green space, and highest levels of deprivation are most vulnerable to heat. We evaluated the approach against previous climate research, examined the approach and datasets at the local scale, and described how heat vulnerability can be (and is being) incorporated into decision making. This project combines three key innovations: (1) the decision-centric process that focuses the method on the decision that needs to be made, minimizing inertia related to scientific or modeling uncertainty and reducing resource-intensity; (2) the co-creation process with Birmingham City Council, who have statutory powers for planning within the city, thereby ensuring that heat vulnerability is embedded within decisions on the suitability, design, and location of sites for future development; and (3) the open access and technically appropriate methodology which can be applied to any urban area in the UK, using the open access datasets described here, or globally, using locally applicable data sources.

“…The KMO is used to compare the correlation and partial correlation coefficient between items, while Bartlett's spherical test is used to test whether the correlation coefficient between items is significant or not. The principal component analysis is usually adopted to calculate the KMO value and the Frontiers in Environmental Science frontiersin.org significance of Bartlett's sphericity test (Azam and Rahman, 2022).…”

Eco-compensation is effective in promoting the sustainable development of a watershed. The exploration of the public’s willingness to pay for such compensation, along with the corresponding influencing factors, are important for improving the efficacy of eco-compensation programs. However, motivating the public to participate in eco-compensation remains a challenge. In this study, the influencing factors behind public willingness to participate in eco-compensation in China’s Taihu Basin are measured using a contingent valuation method and a random forest model. The main results are as follows: 1) In the Taihu Basin, the mean people are willing to pay for eco-compensation is 287.344 CNY/person/year. 2) The significant factors influencing willingness to pay are recognition of the importance of watershed protection; the impact of the watershed environment on people’s lives; annual incomes; and perceived improvements to the watershed environment over the past five years. 3) Awareness of the need for environmental protection can encourage people to pay eco-compensation. This study provides references that governments can use to formulate and implement eco-compensation policies and hence promote public participation in those policies.
