About the talk

On the global scale, the share of water resource consumed by humans is still relatively modest: 7 % of the “blue water” and 9 % of the “green water”, but the distributions in space of the human population and the water resources are significantly different. For example 21.5 % of the humans are concentrated on steppes and in arid zones and have access to only 2 % of the “blue water” resources of the planet. Moreover, the demand for water is increasing because of population growth and changes in food habits, whereas the resources are impacted by climate change.
