Also maintaining rivers and ecosystems: major issue in many parts of the world, reflected in australia in droughts, ultimate sustainable population of australia dependent on water (abundant land, mineral res ources etc) Threats to water security combination of issues: population growth, economic development and urbanisation, climate change. Inefficient water use and wastage (both of water and the foods / goods produced using that w ater) Lower rainfall in many parts of the world: anthropogenic climate change increased temperatures, higher evaporation (rain lost to atmosphere) Increased climate variability (some high rainfall events but more drought years) Increased demands: accompany economic development, australia, average direct urban water use (showers, cooking, laundry, gardens etc) per person = 3.
