Light, reflective surfaces can have a dramatic impact in cooling the surrounding air – in cities, but in the countryside too. Whitewashed walls, arrays of photovoltaic cells, and stubble-filled fields can all provide local relief during the sweltering decades ahead. But policymakers beware. It doesn’t always work like that.
Urbanisation and a changing climate are leading to more frequent and severe flood, heat and air pollution episodes in Britain's cities. Interest in nature-based solutions to these urban problems is growing, with urban forests potentially able to provide a range of regulating ecosystem services such as stormwater attenuation, heat amelioration and air purification.
Buildings and the atmosphere are intrinsically connected via cooling and heating systems. Global climate is projected to grow warmer, while an increasing fraction of the population living in urban centers. This introduces the challenge for new approaches to project future energy demand changes in cities.
The traditional use of water in our cities severely distorts the natural water cycle, consuming potable water for purposes such as toilet flushing and irrigation, whilst discharging excessive volumes of stormwater runoff and wastewater.
Heat-related mortality tends to be associated with heatwaves that do not allow for sufficient acclimatisation to hot temperatures. In contrast, damage functions and most heatwave emergency response plans do not account for acclimatisation.
As cities grapple with the impacts of heatwaves, exacerbated by the urban heat island effect and progressively amplified by climate change impacts, green spaces can cool urban areas, as well as providing many other functions and benefits to city dwellers’ health and wellbeing, and habitat for urban biodiversity.
Knowing what to do with scientific research outcomes can be tricky. But, by changing how we present research proposals or findings to government and industry, we have a real chance to influence policy making and industry practice. The fact sheet covers 9 principles:
1. Know what you want to achieve
2. Bring solutions, not problems
3. Translate the research
The world's population is increasingly urban with more than half the global population already living in cities. The urban population is particularly affected by increasing temperatures because of the urban heat island (UHI) effect.
Resilient Sydney, is the first resilience strategy for metropolitan Sydney.
This strategy sets the direction we must take to strengthen our ability to survive, adapt and thrive in the face of increasing global uncertainty and local shocks and stresses. This strategy calls for business, government, academia, communities and individuals to lead and work as one city.
