In this section of the course, you will learn about some of the major current Global Health challenges at the Human-Animal-Ecosystem Interface and the need for cross-sectoral approaches to health, including One Health, Eco-Health and Planetary Health. Please watch video "Introduction to Section 1" for a more detailed description.

This section focuses on the current global threat posed by zoonotic emerging infections and the tools and challenges for studying and controlling them. Please watch video "Introduction to Section 2" for a more detailed description. Note that many of the topics addressed here (bushmeat, bird migration and avian influenza, etc) are re-discussed in the section 8 of the MOOC.

Antimicrobial resistance is a current top priority in the Global Health agenda. In this section, you will learn about its global burden and the challenges for its control from the national to the global levels based on cross-sectoral approaches to health. Please watch video "Introduction to Section 3" for a more detailed description.

Neglected Tropical Diseases are not neglected in this MOOC and you will have here the opportunity to learn about their common determinants and the interventions and challenges to fight them. Please watch video "Introduction to Section 4" for a more detailed description.

So far we have mainly focused on zoonotic infections, but human-animal interactions can also involve other threats for human health. This section focuses on these conflicts and injuries, paying particular attention to snakebite and the current snakebite crisis. Please watch video "Introduction to Section 5" for a more detailed description.

In this section, we propose you to learn about some innovative approaches, tools, frameworks etc. that offer interesting opportunities for application in Global Health at the Human-Animal-Ecosystem Interface: Citizen Science, Crowdsroucing, Digital Epidemiology and Big Data etc. Please watch video "Introduction to Section 6" for a more detailed description.

So far, in this course we have mainly focused on health risks. In this section, we have also tried to bring the positive impacts on health that emerge from human-animal interactions and more widely from interactions with ecosystems. You will learn about the notion of Environmental Health from a historical perspective and the importance of ecosystem services for human health, including the benefits on health of owning companion animals. Please watch video "Introduction to Section 7" for a more detailed description.

This section was created in close collaboration with the World Health Organization (WHO) and the Convention on Biological Diversity (CBD) with the goal of highlighting the importance of sustainable management of ecosystems for human health, particularly in the context of climate change. You will be introduced to core issues, challenges and opportunities at the intersection of food systems -including both agricultural biodiversity and sustainable fisheries- and human health against a backdrop of global environmental change. Differential gender impacts are also considered, with a dedicated lecture on the theme and as a cross-reference in other sub-themes. This section is introduced by the Director-General of WHO Dr. Tedros Adhanom Ghebreyesus and by Cristina Romanelli from the Secretariat for the Convention on Biological Diversity.
