Status of terrestrial ecoregions - threats and vulnerabilities
In a World Wildlife Fund for Nature (WWF) study, experts identified 200 periority terrestrial ecoregions - defined as large scale ecological systems with characteristic flora, fauna and climate with high priority for conservation. Furthermore, as presented in this map, the 200 ecoregions were ranked based on their current and future threats and conservation status. From the study - 47% of the terrestrial ecorgions are considered critical or endan...

Population density in drylands of the World
Drylands, the arid regions of the World between temperate regions and deserts, are subjects to long seasons with very little precipitation and drought spells sometimes lasting over several years. The most densely populated dryland regions are in developing countries, and the economies in this zone are vulnerable to issues like drought.

Coastal population and altered coastal zones
Coastal areas with high population densities are those with the most shoreline degradation or alteration. Densely populated areas close to seas are also the most attractive for a lot of economic activity. The graphic shows the proportion of the population that lives within 100 km of the coast, for each of the world's nations and where there are coastal zones with high degree of human alteration (compared to 'natural' landcover). In addition, the ...

Natural hazard hotspots, by risk type
Disasters and natural hazards represents one strong aspect of vulnerability for the exposed and poor of the World. With climate change, the frequency of certain natural hazards are expected to increase. This map presents an output from an analysis investigating hazard exposure and historical vulnerability for selected natural hazards, together with population distribution and economy. Specifically, this map provides information on what natural ha...
