The role of the private sector and citizens in urban climate change adaptation : Evidence from a global assessment of large cities

Expectations of cooperation between local authorities, the private sector, and citizens in climate change adaptation in cities are high because involvement of many actors is seen as critical to success. Scholars and policymakers argue that the private sector could be more efficient than the public authorities in implementing adaptation measures and argue for the need to engage citizens to ensure legitimacy of adaptation and inclusion of locally relevant knowledge. To what extent do cities address the private sector and citizens in their adaptation initiatives? What modes of governance do they use to do this? What kinds of cities are the most likely to address the private sector and citizens? Going beyond the existing case study approaches, this paper answers these questions using a large N data set covering 402 cities around the world. We find that a majority of adaptation initiatives focus exclusively on the public sector and do not address the private sector or citizens. In the cases where they do, the private sector is more often governed through partnerships and participation, whereas citizen participation is relatively rare. Initiatives involving citizens rely more often on a provision of information that encourages citizens to adapt. We find that the more advanced a city is in its adaptation process, the more likely it is to address the private sector than citizens in its initiatives to adapt to climate change. Whereas with partnerships and participation the private sector can influence urban adaptation arrangements at a broader scale, the provision of information allows citizens only to implement individual adaptation measures according to their capacities.Peer reviewe

Public Health Adaptation to Climate Change in Canadian Jurisdictions

Climate change poses numerous risks to the health of Canadians. Extreme weather events, poor air quality, and food insecurity in northern regions are likely to increase along with the increasing incidence and range of infectious diseases. In this study we identify and characterize Canadian federal, provincial, territorial and municipal adaptation to these health risks based on publically available information. Federal health adaptation initiatives emphasize capacity building and gathering information to address general health, infectious disease and heat-related risks. Provincial and territorial adaptation is varied. Quebec is a leader in climate change adaptation, having a notably higher number of adaptation initiatives reported, addressing almost all risks posed by climate change in the province, and having implemented various adaptation types. Meanwhile, all other Canadian provinces and territories are in the early stages of health adaptation. Based on publically available information, reported adaptation also varies greatly by municipality. The six sampled Canadian regional health authorities (or equivalent) are not reporting any adaptation initiatives. We also find little relationship between the number of initiatives reported in the six sampled municipalities and their provinces, suggesting that municipalities are adapting (or not adapting) autonomously

The Government-Led Climate Change Adaptation Landscape in Nunavut, Canada

The Canadian Arctic is uniquely sensitive to climate change impacts, including rapidly warming temperatures, sea ice change and permafrost degradation. Adaptation—including efforts to manage climate change risks, reduce damages, and take advantage of new opportunities—has been identified as a priority for policy action across government levels. However, our understanding of adaptation in the Canadian North is limited: Is adaptation taking place, to what stresses, and what does it look like? In this paper we answer these questions for the Inuit territory of Nunavut, systematically cataloguing and reviewing government-led adaptation programs and policies at community, territorial, and federal levels, drawing on publically available information. A total of 700 discrete adaptation initiatives were documented. The focus on adaptation to-date has primarily been at the groundwork level, aimed at informing and preparing for adaptation through impact assessments, adaptation planning exercises, and stakeholder engagement. Adaptation in Nunavut has been driven by cross-scale co-ordination and leadership from the territorial and federal government. Our study finds few examples of concrete actions for planned adaptation, such as changes to or creation of policies that enable adaptation, alterations to building codes and infrastructure design with changing geo-hazards, or enhanced disaster planning and emergency preparedness in light of projected impacts. Adaptation thus remains in its early stages, and this study indicates a need for formal adaptation plans for the Governments of Canada and Nunavut, emphasis on adaptation monitoring and evaluation, and a greater role of Inuit traditional knowledge and cultural values in adaptation policy.

Climate change adaptation planning in large cities : A systematic global assessment

Cities globally face significant risks from climate change, and are taking an increasingly active role in formulating and implementing climate change adaptation policy. However, there are few, if any, global assessments of adaptation taking place across cities. This study develops and applies a framework to track urban climate change adaptation policy using municipal adaptation reporting. From 401 local governments globally in urban areas with >1. m people, we find that only 61 cities (15%) report any adaptation initiatives, and 73 cities (18%) report on planning towards adaptation policy. We classified cities based on their adaptation reporting as extensive adaptors, moderate adaptors, early stage adaptors, and non-reporting. With few exceptions, extensive adaptors are large cities located in high-income countries in North America, Europe, and Oceania, and are adapting to a variety of expected impacts. Moderate adaptors usually address general disaster risk reduction rather than specific impacts, and are located in a mix of developed and developing countries. Early stage adaptors exhibit evidence of planning for adaptation, but do not report any initiatives. Our findings suggest that urban adaptation is in the early stages, but there are still substantive examples of governments taking leadership regardless of wealth levels and institutional barriers

Opinion: Big data has big potential for applications to climate change adaptation

The capacity to collect and analyze massive amounts of data is transforming research in the natural and social sciences (1). And yet, the climate change adaptation community has largely overlooked these developments. Here, we examine how “big data” can inform adaptation research and decision-making and outline what’s needed from the adaptation community to maximize this opportunity. We contend that careful application of big data could revolutionize our understanding of how to manage the risks of climate change

Equity in human adaptation-related responses: A systematic global review

Growing evidence suggests that climate adaptation responses that do not incorporate equity considerations may worsen inequality and increase vulnerability. Using data from a systematic review of peer-reviewed empirical research on adaptation responses to climate change (n = 1,682), we present an assessment of how social equity is considered in adaptation across regions, sectors, and social groups. Roughly 60% of peer-reviewed literature on adaptation responses considers social equity by reporting on which marginalized groups were involved in planning or implementation. Articles on responses in Africa and Asia and those focusing on poverty reduction most frequently considered social equity. Equity was less likely to be considered in adaptation responses in Europe, Australasia, and North America, as well as in literature focused on cities. Income-based inequity was more frequently considered than gender, age, or Indigenous status. Ethnic and racial minorities, migrants, and people with disabilities were rarely considered. Attention to the levels and forms in which equity is integrated into adaptation research and practice is needed to ensure just adaptation
