What are the 4 main causes of water scarcity?
Major Causes of Water Scarcity
- Climate change.
- Natural calamities such as droughts and floods.
- Increased human consumption.
- Overuse and wastage of water.
- A global rise in freshwater demand.
- Overuse of aquifers and its consequent slow recharge.

Water Scarcity. Water scarcity can mean scarcity in availability due to physical shortage, or scarcity in access due to the failure of institutions to ensure a regular supply or due to a lack of adequate infrastructure.
How can we stop water scarcity?
Managing Water Scarcity
- Installing special tanks that store rainwater for irrigation.
- Using drip irrigation for more efficient watering.
- Establishing schools for farmers where they learn how to adapt to climate change with drought-resistant crops, crop rotation, and sustainable ways to raise livestock.

How do you measure scarcity?
Following Barnett and Morse (1963), economists have largely employed two measures of economic scarcity: the real cost (labor plus capital) of extracting a unit of the resource and the price of the resource relative to other goods and services.
How is water availability measured?
Water availability (WA) is obtained from natural stream flow (QNSF ) by subtracting existing storage (ST), out-of-stream consumptive uses (CU) and in-stream demands (IS). Ideally, water availability would be calculated for every watershed above a point of diversion or instream demand.
What is WWF water?
WWF is working to protect freshwater ecosystems and improve water access, efficiency, and allocation for people and the environment – an essential component of saving most of WWF’s priority places and species and reducing the impact of humanity’s water footprint.

Water scarcity is a physical, objective reality that can be measured consistently across regions and over time. “Water stress” refers to the ability, or lack thereof, to meet human and ecological demand for water.
How do you calculate water stress?
stress to be computed as ratio of product of domestic water demand (km3/yr), Industrial water demand (km3/yr) and Agricultural water demand (km3/yr), to water supply (km3/yr). – Value less than 0.4 implied Population exposed to water stress .
What are the effects of water scarcity?
When waters run dry, people can’t get enough to drink, wash, or feed crops, and economic decline may occur. In addition, inadequate sanitation—a problem for 2.4 billion people—can lead to deadly diarrheal diseases, including cholera and typhoid fever, and other water-borne illnesses.
