In the hilly and gully regions of Northwest Loess Plateau in Northwest China, arid and dry land areas in North China and dry mountainous areas in southwestern China, 13 provinces (municipalities and autonomous regions) across 742 counties (cities) covering an area of about 20 million square kilometers and a population of about 2.6 billion, lack of water resources, and regional and seasonal drought and water shortage. This is particularly true of cities in these regions, with serious over-exploitation of groundwater, falling water levels and subsidence of the ground, and the urgent need of introducing rainwater harvesting projects into the cities so that the enormous potential of natural rainfall can be effectively utilized
