Abstract: | Urbanisation is increasing and today more than a half of the world’s population lives in urban areas. Cities, especially those
where urbanisation is un-planned or poorly planned, are increasingly vulnerable to hydro-meteorological hazards such as heat
waves and floods. Urban areas tend to degrade the environment, fragmenting and isolating ecosystems, compromising their capacity
to provide services. The regulating role of ecosystems in buffering hydro-meteorological hazards and reducing urban vulnerability
has not received adequate policy attention until now. Whereas there is a wide body of studies in the specialised biological
and ecological literature about particular urban ecosystem features and the impacts of hazards upon people and infrastructures,
there is no policy-driven overview looking holistically at the ways in which ecosystem features can be managed by cities to
reduce their vulnerability to hazards. Using heat waves and floods as examples, this review article identifies the aggravating
factors related to urbanisation, the various regulating ecosystem services that buffer cities from hydro-meteorological impacts
as well as the impacts of the hazards on the ecosystem. The review also assesses how different cities have attempted to manage
related ecosystem services and draws policy-relevant conclusions. |
