What Is water deficit and where is it
The south and east ( where rainfall is lower) has a water deficit where demand exceeds supply.
What are water transfer schemes? And why is there opposition?
Water transfer schemes move water from areas with water surplus to areas where this is water deficit. There is opposition because it costs a lot, potential damage to the ecosystems and greenhouse gases are produced
How are people managing agricultural pollution
