What is the Importance of Water?

Water is essential for life as it plays a critical role in many biological processes. In the absence of water, humans can survive only for a few days because it is necessary for maintaining cellular balance and sustaining life. Water’s special characteristics help ecosystems and maintain environmental balance. Lack of clean water poses challenges for communities in fulfilling basic needs, achieving economic growth, and protecting the environment.

Let’s examine the various ways in which water influences our daily lives.

Importance of Water in the Environment

Approximately 71% of the Earth’s surface is covered by water, mainly in the form of seas and oceans, which account for around 96.5% of total water volume. However, only a small fraction, 1%, is suitable for use. Ecosystems depend on water for a variety of purposes:

• Water provides oxygen, nutrients, minerals and has a vital role in metabolic processes like Photosynthesis and respiration in plants and animals.
• Water also conserves most of the diversity. It supports the growth of vegetation, provides food and shelter for many organisms.
• Inadequate water resources can lead to ecosystem imbalance, habitat degradation, and loss of biodiversity.

Importance of Water in Agriculture

Water is essential for crop production and raising livestock.

• About 70% of freshwater from various sources including surface water, groundwater, rainwater, and municipal water systems is dedicated to agriculture.
• Agricultural water is used for irrigation, pesticide and fertilizer applications, crop cooling, and frost control. Irrigation systems accounts for 80 to 90% of total agricultural water consumption.
• Adequate water supply is crucial for enhancing agricultural yields and livestock hydration. It ensures food security and maintains livelihoods.

Importance of Water for Industries and Economy

Water serves a crucial function in the manufacturing industry. Water is essential for various industrial processes, such as manufacturing, power generation and for waste disposal.

• Many industrial manufacturing processes are based on use of water as a solvent in chemical reactions or cooling equipment used in creating their products.
• In addition, industries also generate profits through water-based activities such as tourism, fishing, and shipping. Fishing in both saltwater and freshwater is a significant food source for many regions worldwide.
• Hydroelectricity, also known as hydropower, is a low-cost, eco-friendly renewable energy source that uses the energy of running water to generate electricity.
• However, industrial activities can lead to water pollution and resource depletion, emphasising the need for sustainable water management practices to support economic growth without compromising environmental integrity.

Importance of Water for Human Health

The water in human body percentage ranges from 55 to 78%. Normally, the human body needs 1 to 7 litres of water daily for proper function, based on various factors like activity level, temperature, humidity, and other factors. Water intake includes not only drinking water but also water from food and drinks.

Water is the source of life. It is essential for the survival of all living beings. It regulates body temperature, aids digestion, and facilitates nutrient absorption. Adequate water intake is crucial for overall health, promoting hydration, and supporting vital processes within the body. Conserving and responsibly managing water resources is important for maintaining ecological balance and the preservation of biodiversity. Let’s examine the various ways in which water influences our daily lives.
