The introductory article, here, explains the remit of the pieces. The paragraph below seems to provide a helpful context to understand this:
The theme for this issue of Environment and Urbanization (our fiftieth issue) draws on Mark Pelling’s book on Adaptation to Climate Change: From Resilience to Transformation. (4) The focus on resilience and transformation was conceived as a theme that is of relevance to all urban settings, namely how the capacities to withstand or recover from all direct and indirect impacts of climate change (resilience) can be developed while also contributing to the so much-needed transformation to a low carbon (local and global) economy where everyone’s needs are met – and to achieve this quickly enough to avoid dangerous climate change. This has, as a central component, the delinking of successful cities, towns and rural settlements (and their inhabitants’ consumption patterns) from high greenhouse gas emissions. Of course, these are inter-connected, since reducing greenhouse gas emissions globally reduces the direct and indirect impacts of climate change.
In all there is access, either on the main page, linked above, or attached to the articles (including the first), to around sixty pieces, all connected by the interface of Urban society, climate change action and the notion of resilience.
There's way more than a couple of days reading here, but recent commentary at Stoat (look at the comments thread, in particular), suggests that, as a resource, this will be of interest and value to a number of us who attempt to deal with such issues on the internet and in our thinking.
Enjoy the free access and make the most of the opportunity. This whole package is strongly recommended, not least because it raises interesting points about some of the implicit assumptions and principles which are used.
