This is the third edition of the Ecological Threat Report (ETR), which analyses ecological threats in 228 independent states and territories. Produced by the Institute for Economics & Peace, the report covers over 3,638 sub-national administrative districts, or 99.99 per cent of the world's population, assessing threats relating to food risk, water risk, rapid population growth and natural disasters. The main finding from the 2022 ETR is that without concerted international action, current levels of ecological degradation will substantially worsen, thereby intensifying a range of social challenges, including malnutrition, forced migration and illness.
