Fukuoka: Adapting to climate change through urban green space and the built environment?

This paper profiles Fukuoka City in Kyushu, Japan. We focus on the city's local climate change adaptation policies, and in particular the role of urban and greenspace planning in facilitating adaptation actions within Fukuoka. Fukuoka is a humid subtropical city which is currently experiencing significant population and economic growth. It has also made comparatively rigorous advances in climate adaptation, in a country context where local governments have been criticised for focusing more on mitigation. Fukuoka hence may yield lessons for other rapidly urbanising subtropical Asian cities. We illustrate that Fukuoka has a long tradition of science-policy connection towards the creation of a liveable urban environment. This creates a favourable research and policy infrastructure for adaptation, in particular mitigation of heat risk. This is evidenced in consideration of climate issues within the city's greenspace plans since the 1990s, and in an extensive body of underpinning applied research from local institutions into urban thermal environments in particular. Fukuoka's green terraced ACROS building has come to symbolise adaptation via the built environment, and has been followed by the emergence of further green roofs and through citizen and private sector involvement in smaller-scale greening actions. We caution that challenges remain around connecting different sections of local governments, and in maintaining climate and environmental imperatives in the face of ongoing development and expansion pressures

Balancing conflicting mitigation and adaptation behaviours of urban residents under climate change and the urban heat island effect

Under a warming climate and urban heat island effects, cooling behaviours are increasingly important for city dwellers. Cooling actions, especially air conditioning, receive increasing scrutiny in social science, as does engagement and communication on behaviours spanning adaptation and mitigation. In response, this paper evaluates the relation between residents’ adaptation and mitigation behaviours around cooling in Fukuoka, Japan, and draws lessons for communication on encouraging adaptation and mitigation actions. A survey distributed to residents in six areas of Fukuoka, Japan, assessed perceptions of global warming and urban heat island effects, frequency of mitigation and adaptation behaviours, use of air conditioning, electricity bills and evaluation of green spaces. We observe a difference between respondents using air conditioning with an energy-saving (i.e. mitigation) focus, versus those using air conditioning with an adaptation (i.e. cooling) focus. We also note residents emphasising mitigation behaviours may use shade in parks or cooling centres as alternative cooling strategies, but that awareness of effective air conditioning use may be lacking. Our findings build on existing literature by reinforcing – in a subtropical context – the need to reconsider practices around air conditioner use; and illustrate the value of a breadth of messages to promote joint mitigation and adaptation actions

What is the role of epistemic communities in shaping local environmental policy? Managing environmental change through planning and greenspace in Fukuoka City, Japan

This paper evaluates the role of epistemic communities in shaping local environmental policy, through the case of management of environmental change through planning and greenspace in Fukuoka City, Japan. Amidst increasing global interest in the role of evidence-based policy and urban science in responding to environmental issues in cities, Fukuoka is distinctive. Locally-situated scholars in Fukuoka have, for several decades, sought to shape local responses to environmental change by influencing policy for the built environment and greenspace. Through analysis of scholarly outputs produced by scholars working at universities and research institutes within Fukuoka and policy documentation produced by the city government, we characterise the development of Fukuoka’s urban environmental change epistemic community. We suggest that built environment and greenspace policy to respond to environmental change in Fukuoka has been shaped by an epistemic community in three ways. These are: (a) a common belief in techno-scientific evidence derived from empirical observation; (b) a shared interest in urban planning and greenspace as a vehicle for realising change; and (c) a common normative concern with citizen wellbeing, rooted in negative historical experiences with pollution. We argue that policy formation driven by scholarly expertise in cities may have a greater chance of taking root if there is a favourable historical context of locally-led environmental science research, personal investment of the epistemic community members in the city, and regular dialogue between the epistemic community and wider society in the city. We conclude that a strong and reflexive epistemic community, working in collaboration with environmental and civil society actors, is important in understanding an appropriate response to current urban environmental challenges
