    The developing countries are suffering the most because of climatic variability and they have an enormous backlog in basic infrastructure to protect their cities. In addition, the resources and technical expertise are limited. Therefore, the adaptation measures to protect their cities are needed to be planned and prioritized carefully to reduce the vulnerability simultaneously considering the risk reduction, local constraints and development goals. A framework for prioritization of adaptation measures is lacking in the decision making in this context which could immensely assist in informed and structured decisions during the planning process of adaptation strategies in developing countries. This paper is exploring the potential of Multi-Criteria Analysis as a methodology for climate adaptation assessment in order to prioritize the adaptation measures to be undertaken. Hence in this paper Adaptation assessment is conducted within the framework of Multi-Criteria Analysis methodology which allows both normative judgement and technical expertise in the assessment process. Such a participatory integrated assessment of adaptation options is a new approach in flood management in least developed countries. The assessment framework has been applied and tested at the Eastern fringe of Dhaka city which is highly vulnerable to flooding. Based on the assessment and analysis, adaptive measures are prioritized to enable more effective action

    Are we willing to give what it takes? Willingness to pay for climate change adaptation in developing countries

    Climate change adaptation is gaining traction as a necessary policy alongside mitigation, particularly for developing countries, many of which lack the resources to adapt. However, funding for developing country adaptation remains woefully inadequate. This paper identifies the burden of responsibility that individuals in the UK are willing to incur in support of adaptation projects in developing countries. Results from a nationally representative survey indicate that UK residents are willing to contribute £27 per year (or a median of £6 per year) towards developing country adaptation (US30and30 and 7 using the World Bank’s purchasing power conversion factors). This represents less than one third of the back-of-the-envelope 100140percapitaperyearthattheauthorsestimatewouldbeneededtoraisethe100-140 per capita per year that the authors estimate would be needed to raise the 70-100bn per year recommended by the World Bank to fund developing country adaptation. Regressions indicate that WTP is driven mostly by a combination of beliefs and perceptions about one’s own knowledge levels, rather than actual knowledge of climate change. We conclude that, to engage the many different audiences that make up the ‘public’, communication efforts must move beyond the simple provision of information and instead, connect with people’s existing values and beliefs

    Experimental evaluation of HCFO-1233zd-e as HFC-245fa replacement in an organic rankine cycle system for low temperature heat sources

    [EN] In this work an experimental evaluation of the working fluid HCFO-1233zd-E as HFC-245fa replacement in ORC systems for low temperature heat sources has been conducted. A fully monitored ORC module has been used to test both working fluids at different operating conditions. Due to the different densities of the working fluids, the mass flow rate for HCFO-1233zd-E is approximately 20% lower than for HFC-245fa. This causes thermal and electrical powers to be lower for HCF0-1233zd-E than for HFC245fa. However, net electrical efficiency is similar for both working fluids, ranging from 5% to 9.7% in the tested operating conditions. Regarding the expander performance, various performance indicators are addressed. The expander isentropic performance has a maximum value of 75%, with higher values for HCFO-1233zd-E than for HFC-245fa. The overall efficiency of the expander, similar for both working fluids, ranges from 44% to 57% in the experimental test range. (C) 2016 Elsevier Ltd.

    Coal in the 21st Century: a climate of change and uncertainty

    Get PDF
    Coal presents a particular set of challenges when balancing energy policy goals. Despite presenting viable solutions to the problems of energy security and global energy poverty, coal struggles, given its greenhouse-gas drawbacks, in a world of increasingly harmful climate change. Notwithstanding the harm caused to the environment, coal remains an expanding low-price route to meeting local energy needs. It is forecasted to remain a major global resource for the foreseeable future. In the short term it is predicted to have a 26% share of the global energy mix. Recent years have witnessed severe deviations from previously stable trends in coal markets and policy dynamics. According to the predictions by the International Energy Agency (IEA), a variety of factors ranging from the planned phase-out of coal in countries such as Denmark, France and the UK, to changes in policy in China and import-dependency in India, and demand drop in the US have together resulted in the largest decline in coal production in 2015 since 1971 (IEA, Coal Information, 2016). This paper seeks to outline basic coal facts, recent market trends and directions globally and provides an overview of issues shaping the future of coal in the twenty-first century.

    The role of collaboration in the UK green supply chains: an exploratory study of the perspectives of suppliers, logistics and retailers

    Get PDF
    Many companies around the world have started to realise that working alone will not be sufficient in their move towards a greener supply chain (SC). More specifically, recent UK government regulations on implementing strict CO2 reduction encourage SC operators to work collaboratively, in production and logistics or other operations, to achieve their green objectives. In this research, we look at some underlying factors of SC collaboration, focussing on suppliers, logistics and retailers, for the purpose of improving the environmental sustainability of companies’ SCs. To facilitate our study, we conduct case studies in two overseas supplier companies with the aim of providing a better understanding of how green issues imposed by European and UK customers influence the companies’ actions to meet agreed environmental goals. Based on the initial analysis of the case studies, we develop a conceptual framework which indicates that SC collaboration plays an important role in ensuring companies achieve environmental sustainability of their SCs. Subsequently, staff in middle-management and related roles in sixteen companies operating in the UK are interviewed. This allows us to understand their business practices in terms of SC collaboration with their suppliers and buyers to achieve the goal of CO2 reduction. Finally, drawing upon the information from company reports and websites, a number of UK leading retailers’ actions to reduce CO2 emissions are investigated. We develop a conceptual framework of SC collaboration for environmental sustainability to help companies improve their level of collaboration between suppliers and buyers in terms of meeting their environmental objectives. The proposed framework will serve as a base model for the companies using or considering SC collaboration to achieve their environmental agendas, in line with governmental green regulatory requirements
