Different circumstances require different actions, depending on the finance that is available and the kind of territories in question. For example, the city of Essen is implementing integrated adaptation strategies in an attempt to mitigate environmental threats. These threats are principally an increase in storms and intense rainfall, which cause floods and constitute a health risk.
This specific case study was presented by Kai Lipsius – Manager of Climate Protection at the Environmental Agency in Essen. He explained the solutions adopted in his municipality to convert it from a coal and steel town to a modern, green residential and commercial city. Essen has used both green and gray infrastructure, such as courtyard planting, green corridors and renewal of existing buildings.
The same approach was adopted by New York City in restoring the Howard Beach in Queens after Hurricane Sandy in October 2012, as Joel Paque (Policy Advisor at The Nature Conservancy) explained.
