Institutional arrangements for implementing One Health and Eco-health

Unprecedented changes to ecosystems and agriculture are resulting in complex health challenges (human, animal and
ecosystem) requiring innovative and systemic solutions, such as ecohealth and one health. A central concept of one health
and ecohealth is inter-sectoral work between agriculture, health, environmental and other sectors. Understanding the
priorities, types of institutional arrangements and mechanisms for working is still evolving and can vary greatly depending
on local context and the type of inter-sectoral engagement. Case studies for developing countries in Latin America, Africa
and Asia are reviewed, across the spectrum of cross-sectoral integration. Options for institutional arrangements have
included joint task forces around specific emergencies, the establishment of joint offices for specific diseases, shared labs and
other infrastructure, joint research, integrated disease surveillance, inter-sectoral programs such as veterinary units in public
health departments and delivery of services through one health practitioners. From these we present a framework on
assessing the efficiency, effectiveness and feasibility of different types of institutional arrangements and for better understanding the barriers and bridges to working across sectors in different countries. This includes criteria for assessing impacts
within and between sectors. Lessons learned for prioritizing and implemented joint actions are summarized.
