Climate crisis will cause falling humidity in global cities
8 January 2021: Report in The Guardian “Urban regions around the world are likely to see a near-universal decrease in humidity as the climate changes, a study has found. The research suggests that building green infrastructure and increasing urban vegetation might be a safe bet for cities looking to mitigate rising temperatures. Half of the world’s population lives in urban areas, but cities only account for about 3% of global land surface. Lei Zhao, a scientist from the University of Illinois and the lead author of the paper published in Nature Climate Change, says this has meant that previous climate models have not produced data specific to cities.” Unfortunately the Nature Climate Change article is only available to buy or through subscription. The Guardian article can be accessed here. A longer run through the article is available in Wired – Climate Change Is Turning Cities Into Ovens. The GLA published in 2018 an online London Green Infrastructure Map and a Green Roofs Map and a comprehensive list of policies to support the growth green infrastructure in the capital are set out in the Mayor’s 2018 London Environment Strategy.

Transnational municipal networks and climate change adaptation
April 2020: Paper published in the Journal of Cleaner Production
Volume 257, 1 June 2020. “Cities have increasingly recognised the risks posed by climate change and the need to adapt. To support climate action, cities have formed cooperative networks such as the C40 Cities Climate Leadership Group, the Global Covenant of Mayors and the International Council for Local Environmental Initiatives. However, a lack of scientific evidence exists when it comes to the actual impact of network participation, especially in the context of adaptation. This study is the first to test statistically the association between network membership and progress in adaptation planning in 377 cities globally. The results show that network members are more likely to have started the adaptation process than other cities, and that being a member of multiple networks is associated with higher levels of adaptation planning. Moreover, cities in wealthier countries are more likely to be more advanced in adaptation planning than others. We consider the possible explanations for these results based on the previous literature and information gathered from the networks. The main implications of our study are that network organisations should consider how to encourage the adaptation process among their members and the increased involvement of cities from lower-income countries.” Open access paper available here.
A natural capital account for London
November 2016: The Mayor is to “undertake a natural capital account for London parks and green spaces. Natural capital accounting is a methodology developed by the Natural Capital Committee on behalf of the Department for Food and Rural Affairs (Defra) to establish an accounting framework which values some of the intangible benefits of the natural environment.
“The National Trust has trialled a natural capital accounting framework for the parks network in Sheffield. The London natural capital account will take this framework and test its applicability to a city region.”
The approval form goes on to say that the “outputs will be used to help reveal the economic value of London’s parks and green spaces; a necessary step in order to help develop the business case for green infrastructure as recommended by the London Infrastructure Plan and the Green Infrastructure Task Force report. ”
The full GLA approval document can be accessed here (or directly downloadable here).
The Green Infrastructure Task Force report can be downloaded here and some further background to the Taskforce is available an earlier post here.
How can existing suburban neighbourhoods be best adapted to reduce further impacts of climate change?
23 October 2012: This report sets out that:
- It is in suburbs that the majority of the population will be affected by climate change.
- The impacts of these changes will be felt by people, in terms of, for example, increased heat stress and reduced comfort during hot spells,restrictions on water use, reduced air quality, and stress and costs associated with flooding and storm damage.
- There is no clear process, or delivery mechanism,for adaptation and/or mitigation at the suburban neighbourhood scale.
Download the report from the Suburban Neighbourhood Adaptation for a Changing Climate (SNACC) website here.
