ABSTRACT
This chapter explores the connection between three elements: natural disasters, environment and health, together with the action of International Organizations. Although the expression ‘disaster’ is commonly admitted by the international community as a whole, this is an open concept, usually linked with the idea of an event with catastrophic consequences. The connection between environment–together with climate change implications–health and security, with emergencies and disasters as a backdrop, reflects the interrelationship of all these factors at the national and international levels. International Organizations have paid attention to natural disasters and, in particular, their prevention, preparedness and response. The World Health Organization is one example of this: the connection between complex emergencies, some of them directly related with natural disasters, such as can be seen on the webpage of this specialized agency of the United Nations, is something without doubt.
