Water Demand Facts
Today, 2.1 billion people live without safe drinking water at home; affecting their health, education and livelihoods.[1, 2]
By 2050, the world’s population will have grown by an estimated 2 billion people and global water demand could be up to 30% higher than today.[1, 2]
Agriculture currently accounts for 70% of global water withdrawals, mostly for irrigation – a figure which rises in areas of high water stress and population density. Industry takes 20% of the total, dominated by energy and manufacturing. The remaining 10% goes to domestic use – the proportion used for drinking water is much less than 1%.[1, 2]
Water Availability
Today, around 1.9 billion people live in potentially severely water-scarce areas. By 2050, this could increase to around 3 billion people. Water quality:
• An estimated 1.8 billion people use an unimproved source of drinking water with no protection against contamination from human faeces.
• Globally, over 80% of the wastewater generated by society flows back into the environment without being treated or reused.
WHAT ARE NATURE-BASED SOLUTIONS (NBS)?
“Restoring forests, grasslands and natural wetlands, reconnecting rivers to floodplains, creating buffers of vegetation along water courses – these are all examples of NBS that help the management of water availability and quality” explained Prof. Monowar Khalid, Head, Department of Environmental Science, Integral. Planting trees, reconnecting rivers to floodplains, and restoring wetlands will rebalance the water cycle and improve human health and livelihoods.
Trees are considered natural sponges, which regulate the earth’s water supply by holding water. Forest waste matter, such as decomposing leaves or humus, slows down surface evaporation from the soil. Rain first falls on leaves and plants rather than directly hitting the soil, decreasing the rate of water and soil erosion. The Integral Campus is spread over an area of more than 120 acres, with a prime focus on a dense green cover. It’s the first lesson that the student gets, to coexist and study in the lap of nature.
