The International Research Network (IRN) or Groupement de recherche international (GDRI) " Ecosystem health and environmental disease ecology " has been created and accredited by the CNRS in 2013, with the objective of promoting exchanges and bringing better legibility to research in Asia and Europe linking ecosystem health (e.g. the long-term sustainability of ecological processes and the integrity of ecosystem services) and disease ecology (e.g. the processes by which diseases can be maintained or controlled in a given ecosystem). This network brings together specialists of 16 research departments of 6 countries (Australia, China, France, Germany, Japan, UK) in conservation, population biology, landscape and community ecology, geography, parasitology, modelling and health sciences. It also mobilises networks of stakeholders in agriculture, conservation and public health to address questions related to the multi-scale anthropogenic disturbance of regional ecosystems. Three specific issues are currently covered: (1) Ecology of Cestode transmission in Asia and Europe, (2) Ecosystem health and wildlife management (3) Permanent workshop on adaptive monitoring and data management. We believe that earlier and current results obtained about interactions between landscape, small mammal and carnivore population dynamics and the transmission of pathogen agents, especially Echinococcus multilocularis, provide a solid ground and concepts for broader ecosystem studies and research development on other pathogens and other animal communities, and also for applying those concepts and methods to conservation issues. Stress is on the long term monitoring of host and pathogen parasite population dynamics on local and regional scales, on data management and on advanced methods for statistical and spatial modelling, including those combining remote sensing, GIS and molecular genotyping to characterize populations. Long term monitoring and multi-scale investigation are crucial for the improved management of ecosystems and natural resources (e.g. in the context of global changes, etc.) and also for public health actions (disease emergence, etc.). Data were collected consistently in Europe and Asia, in the spirit of adaptive monitoring schemes during earlier programmes by IRN EHEDE members. This allows us to develop new programmes about the long term evolution of ecosystem health and disease transmission sometimes 10-20 years after the baseline was established (e.g. in France, Ningxia, Gansu, etc.).
