Study Notes
Importance of Water
Water is essential for all forms of life, from microorganisms to humans. It plays crucial roles within organisms, such as maintaining body temperature through sweating and respiration, lubricating joints, transporting nutrients and waste products, regulating metabolism, removing toxins, protecting organs, and maintaining cell structure and function. In addition to its biological functions, water serves several other vital purposes:
-
Agriculture
- Irrigation and flood irrigation are two primary methods used to supply water to crops. Irrigation accounts for around 70% of global freshwater withdrawals.
- Precision agriculture uses sensors, climate models, satellite imagery, and advanced equipment to match crop needs with available moisture levels and soil conditions. This helps farmers optimize their production per unit of water.
-
Cleaning and Hygiene
- Clean drinking water is necessary for hygienic practices like washing hands, face, and body, which are critical for preventing the spread of diseases.
- Access to safe sanitation systems is also important, as unsanitary practices can lead to the contamination of water resources and subsequent outbreaks of illnesses.
-
Industrial Processes and Energy Generation
- Industries rely on water for cooling processes, chemical reactions, cleaning operations, and the transportation of commodities.
- Thermal power plants require large amounts of water to cool down electricity generators.
- The water footprint of industries varies widely. For example, the textile industry consumes around 70 million cubic meters of water annually to produce cotton, while the meat production sector uses about 2.5 times more than the textile industry.
Water also plays an essential role in our social life, including recreational activities like swimming, fishing, boating, and other forms of aquatic sports. However, it is crucial for us to understand its importance beyond just these practical applications. By valuing water in all aspects of our lives, we can make better use of the resources available to us and ensure their sustainable management for future generations.
