Page - 334 - in Biodiversity and Health in the Face of Climate Change

334 Part of the discussion concerned the characteristics of ecosystem services related to health: quality of green spaces in relation to health and how people are exposed to different types of nature. Further, an overview of specific ecosystem services and disservices relevant to health were discussed. Apart from green space, the role of both food and perception were discussed. Part of the discussion concerned issues important for research and mainstreaming. Dealing with complexity was at the core of the discussion about research challenges. In addition, the work could be well related to the health sector, both in terms of indicators and research methods, but also in terms of needs: what kind of information is needed for uptake in the health-care sector? 15.2.1.3 What Works Well What works well is occasionally bringing together a diversity of experts interested in both ecosystem services and the links with human health. This helps to mainstream the health perspective in the field of ecosystem services and to discuss opportunities and challenges. Obviously, this seems to work best at ESP conferences. What also works quite well is collecting information about bridge-building challenges in the survey discussed here. 15.2.1.4 Main Challenges The main challenges seem to be keeping momentum and activities alive in the TWG.  This is based on voluntary work from the initiating experts, who often lack time and resources to work for the TWG and to participate in all international ESP conferences. Getting regular inputs from other experts interested in the theme and the TWG is not straightforward and needs more work.

Zinsstag et  al. (2011) propose One Health as an approach aimed at tackling complex patterns of global change, in which the inextricable interconnection of humans, pet animals, livestock and wildlife with their social and ecological environment is evident, and requires integrated approaches to human and animal health and their respective social and environmental contexts.
