Many areas in the world already face water shortages today – situations in which the demand for water is higher than its availability. The UN 2016 World Water Development Report states that demand will exceed availability by 40% in 2030. A growing world population - to 9 billion in 2050 - with higher consumption levels due to overall increases in wealth, leads to higher water demands: up to 55% higher, according to the 2030 World Resources Group. At the same time, the IPCC expects climate change will lead to reduced water availability or longer dry periods in various regions of the world.
In the US Presidential Memorandum on Climate Change and National Security of September 2016, President Obama states “Climate change poses a significant and growing threat to national security, both at home and abroad. Climate change and its associated impacts affect economic prosperity, public health and safety, and international stability.”
The impact of future changes in global population, urbanisation, economic growth, climate change, energy and food production influence societal and (geo) political relations, both within and between countries... Knowledge of the system processes and dynamics governing water are key to explore actionable measures and potentially decrease the impact of changes in water availability on violent conflict risk. As Deltares we have this integrated system knowledge of water and therefore answer to the call of this important societal topic.
