This year is the fifth edition of the Ecological Threat Report, which analyses ecological threats in 207 independent states and territories. The report covers 3,518 sub-national areas which account for 99.99 per cent of the world’s population. The ETR assesses threats relating to food insecurity, water risk, natural disasters, and demographic pressure.

The research takes a multi-faceted approach by analysing ecological threats at the national, subnational, and city level, while also assessing the threats against societal resilience and levels of peace. Comparing ecological threats against societal resilience enables IEP to identify the global regions, countries, and subnational areas most at risk of an ecological disaster, both now and into the future.
