The Challenges of Water Scarcity
Water scarcity is a global challenge with rapid population growth around the world placing extreme pressure on finite water resources.
The United Nations forecasts the world’s population will increase from seven billion today to 9.7 billion by 2050, leading to a 55 per cent increase in demand for water. As a result more than 40 per cent of people will be living in areas of severe water stress — defined as where demand for water regularly exceeds supply.
To feed a growing population, food supply must rise by 60 per cent across the globe, meaning agriculture, which already uses 70 per cent of all water taken from rivers and groundwater reserves, will need an even bigger share of the world’s water supply.
The strain on a diminishing water supply will be felt most acutely in cities as rapid urbanisation continues unabated.
