Opinion: How can cities build resilience while avoid eroding it somewhere else?

The world is increasingly urban, interconnected and shifting, writes Thomas Elmqvist. The world’s 20 fastest growing urban regions are in countries like China, India and Nigeria, not Europe or North America. By 2050, almost three billion more people will live in cities and the world will have undergone the largest and fastest period of urban expansion in all of human history.

Over the last decades there has been increasing recognition that human domination and the rapid development of global urbanism is reshaping the ecology of the entire planet. This rapid urbanization represents major challenges but also opportunities to ensure basic human welfare and a viable global environment.

The opportunity lies in that urban landscapes are the very places where knowledge, innovation, human and financial resources for finding solutions to global environmental problems are likely to be found.

Recent studies indicate that urban biodiversity contributes to multiple ecosystem services that are of great importance for people’s well-being. These include reductions in local air pollution and noise; reductions in the urban ‘heat island’ effect, direct health benefits, and key environments for enhanced public ecological knowledge and awareness of local to global sustainability challenges.

Understanding how urban ecosystems work, how they change, and what limits their performance, can also add to the understanding of ecosystem change, governance and resilience in general in an ever more human-dominated world.

Urban ecosystems, such as urban ‘green and blue spaces’ may have a crucial role in building the necessary capacity to cope with environmental changes. In many cities, like New York, New Orleans, Berlin, Singapore and Cape Town, investments in tree planting, ‘green roofs’ and ecological restoration projects are now growing rapidly as part of a low-carbon strategy to increase this capacity to adapt.

We at the Urban Theme at Stockholm Resilience Center of Stockholm University have built an extensive network of research groups in cities around the world, and led a number of interdisciplinary projects. This includes the pan-European project Urban Biodiversity and Ecosystem Services (URBES) focused on quantifying and valuing urban ecosystem services and exploring ways in which they could be incorporated into urban planning and policy in a European context.

Our studies have generated important insights into what role informal institutions and civic management play in supporting ecosystem services in urban areas. Such management is non-governmental in character and depends on private and civic interest groups.

We have taken a novel approach of studying ecosystem management under common property rights systems in urban settings and contributed to the concept of ‘ecological land-use complementation’—the idea that land uses in urban green areas could interact to support biodiversity when clustered together in different combinations. These approaches analyse the resilience building of urban landscapes and could be viewed as building capacity to deal with ecosystem loss in the face of increased urbanization. They also examine how cities could build resilience without eroding it elsewhere.

Thomas Elmqvist leads the theme ‘Urban social-ecological systems and globalization’ at the Stockholm Resilience Centre, Stockholm University. This aims to build knowledge around the management, planning, generation/distribution and design of ecosystem services and biodiversity in metropolitan landscapes. The URBES project is being implemented in cooperation with IUCN.

IUCN is pleased to hear that there is a great interest to raise awareness in Asia and other parts of the world for biodiversity in an urban context. We welcome all initiatives that increase the understanding of the functioning of urban ecosystems and appreciate your efforts to involve youth groups as well. IUCN is developing activities for urban biodiversity conservation and aims to include all groups in society

2 Jia Ran school
I was a volunteer for Greenpeace - Jia Ran, and I has been very concerned about the Environmental public welfare .And I would like to organize an environmental seminars in school,in order to improve everyone's awareness of environmental protection and encourage more students to participate in environmental protection work.So we sincerely hope to be able to invite your organization to do for us once environmental seminars.Thank you!
This is my

European biodiversity is closely interlinked with urban develoment
I agree with the prvious comment that there is more undisturbed biodiversity in Asia. The challenge for Europe is to find the balance between urban and industrial development, agriculture and nature conservation. Linking biodiversity rich areas to provide connectivity, is very important in the patchwork of the European landscape.

of course, i agree and respect your views
of course, i agree and respect your views but there is yet greater bio-diversity and preserved natural resources in India and some Asian countries compared to Europian countries
