We use a suite of decadal-length regional climate simulations to quantify potential changes in population-weighted heat and cold exposure in 47 US metropolitan regions during the 21st century. Our results show that population-weighted exposure to locally defined extreme heat (i.e., “population heat exposure”) would increase by a factor of 12.7–29.5 under a high-intensity greenhouse gas (GHG) emissions and urban development pathway. Additionally, end-of-century population cold exposure is projected to rise by a factor of 1.3–2.2, relative to start-of-century population cold exposure. We identify specific metropolitan regions in which population heat exposure would increase most markedly and characterize the relative significance of various drivers responsible for this increase. The largest absolute changes in population heat exposure during the 21st century are projected to occur in major US metropolitan regions like New York City (NY), Los Angeles (CA), Atlanta (GA), and Washington DC. The largest relative changes in population heat exposure (i.e., changes relative to start-of-century) are projected to occur in rapidly growing cities across the US Sunbelt, for example Orlando (FL), Austin (TX), Miami (FL), and Atlanta. The surge in population heat exposure across the Sunbelt is driven by concurrent GHG-induced warming and population growth which, in tandem, could strongly compound population heat exposure. Our simulations provide initial guidance to inform the prioritization of urban climate adaptation measures and policy.

Climate change amplifies social, political, economic, infrastructural and environmental challenges in many Global South cities, and perhaps no city is more vulnerable than Bangladesh’s capital of Dhaka. Climate-induced rural–urban migration is a profound concern, and Dhaka’s political leaders have embraced technology-based innovation as one solution pathway. This article explores the societal impact of Dhaka’s innovation environment strategies for climate change adaptation and mitigation. Employing a case study qualitative methodology, our three findings expand knowledge about innovation for urban climate adaptation and mitigation as understood by Dhaka-based entrepreneurs. First, the most effective innovations were not the most technologically advanced, but those with the highest degree of participant ownership. Second, gaps between recipient, corporate and governmental understandings of effective mitigation and adaptation harmed projects were driven by different definitions of risk and competing understandings of vulnerability. Third, even the most technical climate adaptation measures were inherently political in their application. We discuss how to better position urban climate innovation infrastructures in Bangladesh and beyond, including developing a better recognition of innovation lifecycles for urban climate adaptation and widening our definitions of “innovation” to better incorporate more effective and inclusive climate adaptation solutions.

Traditional agroforestry systems across South Asia have historically supported millions of smallholding farmers. Since, 2007 agroforestry has received attention in global climate discussions for its carbon sink potential. Agroforestry plays a defining role in offsetting greenhouse gases, providing sustainable livelihoods, localizing Sustainable Development Goals and achieving biodiversity targets. The review explores evidence of agroforestry systems for human well-being along with its climate adaptation and mitigation potential for South Asia. In particular, we explore key enabling and constraining conditions for mainstreaming agroforestry systems to use them to fulfill global climate mitigation targets. Nationally determined contributions submitted by South Asian countries to the United Nations Framework Convention on Climate Change acknowledge agroforestry systems. In 2016, South Asian Association for Regional Cooperation’s Resolution on Agroforestry brought consensus on developing national agroforestry policies by all regional countries and became a strong enabling condition to ensure effectiveness of using agroforestry for climate targets. Lack of uniform methodologies for creation of databases to monitor tree and soil carbon stocks was found to be a key limitation for the purpose. Water scarcity, lack of interactive governance, rights of farmers and ownership issues along with insufficient financial support to rural farmers for agroforestry were other constraining conditions that should be appropriately addressed by the regional countries to develop their preparedness for achieving national climate ambitions. Our review indicates the need to shift from planning to the implementation phase following strong examples shared from India and Nepal, including carbon neutrality scenarios, incentives and sustainable local livelihood to enhance preparedness.

Climate change means that buildings must greatly reduce their energy consumption. It is however paradoxical that climate mitigation in Denmark has created negative energy and indoor climate problems in housing that may be made worse by climate change. A literature review has been carried out of housing schemes where climate mitigation was sought through reduced space heating demand, and it is shown that extensive problems with overheating exist. A theoretical study of regulative and design strategies for climate mitigation in new build housing has therefore been carried out, and it is shown that reducing space heating with high levels of thermal insulation and passive solar energy results in overheating and a growing demand for cooling. Climate change is expected to reduce space heating and increase cooling demand in housing. An analysis of new build housing using passive solar energy as a climate mitigation strategy has therefore been carried out in relation to future climate change scenarios. It is shown that severe indoor comfort problems can occur, questioning the relevance of passive solar energy as a climate mitigation strategy. In conclusion, a theoretical study of the interplay between climate adaptation and mitigation strategies is carried out, with a cross-disciplinary focus on users, passive design and active technologies. It is shown that the cumulative use of these strategies can create an adaptation buffer, thus eliminating problems with overheating and reducing energy consumption. New build housing should therefore be designed in relation to both current and future climate scenarios to show that the climate mitigation strategies ensure climate adaptation.

Transnational actors are critical for financing programs and generating awareness around climate change adaptation in cities. However, it is unclear whether transnational support actually enables more authority over adaptation actions and whether outcomes address wide-ranging development needs. In this article, I compare experiences from three cities in India—Surat, Indore, and Bhubaneswar—and link local political agency over adaptation with their supporting transnational funders. I find that adaptation governance involves powers of agency over directing bureaucratic practices, public finance, spatial strategies, and institutional culture. A city’s ability to exert these powers then yields different patterns of adaptation. However, political agency is circumscribed by a combination of historical political economic constraints and emerging transnational resources that promote specific forms of political meaning and procedures. The presence of external support therefore paradoxically constrains the governance autonomy of cities. This opens up new opportunities for development dependency—that is, ones that mirror neoliberal critiques of foreign aid—within the global marketplace for climate finance.

Adaptation And Mitigation

Purpose This study identified the attitudes and behaviors of college students regarding their advocacy for climate change adaptation and mitigation. Specifically, perceptions of climate change were assessed and advocacy activities were identified for climate change and/or other topics. Design/methodology/approach Using convenience sampling, students (n = 440) from three universities in the Midwest, the USA, completed surveys assessing their level of agreement with activities related to civic engagement, climate change and policy. Semantic differential scales focused on “learning about climate change,” “advocating for climate change mitigation” and “advocating for climate change adaptation.” Three open-ended questions were used to identify student experiences with civic engagement and/or service-learning, as well as topics in which they advocate and how they advocate. Findings Regarding advocacy in general, over 50% of the sample did not advocate for any topic, with 24.5% of students stating they advocated for the environment/climate change. Students who identified as female, democratic and 1st or 2nd year in school were more likely to be engaged with environmental advocacy. Regarding civic engagement, seniors were more actively engaged with their communities and also more likely to vote in local, state and national elections. Research limitations/implications Time of data collection was a potential limitation with schools conducting data collection at different time periods. Students who identified more progressive politically were also more likely to participate in the study. Originality/value While research exists regarding student civic engagement levels, this research project identified ways in which students engaged in advocacy, identifying potential links with civic engagement and enhanced participation in climate change adaptation and mitigation strategies.
