- Major Causes of Water Scarcity
- Water Stress
The causes of water scarcity are aplenty. However, we must first understand the term water scarcity.
Water scarcity refers to the situation where potable, unpolluted water is lower than the demand in a region.
According to recent reports, nearly 1.2 billion people lack access to clean drinking water. Furthermore, water shortages can cause a variety of illnesses which can range from food poisoning to cholera.
Typically, water scarcity is driven by two important factors – which are the increasing use of freshwater and the depletion of usable freshwater resources. Furthermore, scarcity can be of two types – physical water scarcity and economic water scarcity. Physical water scarcity is caused when a natural water resource is unable to meet the demands of a particular region. Economic water scarcity is caused by the mismanagement of sufficiently available water resources. However, there are a lot more causes of water shortage:
Major Causes of Water Scarcity
Following are some of the major causes of water shortage:
- 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 Stress
When an individual is water-stressed, it implies that there is no sufficient access to potable water. An estimated 1.1 billion people are under water stress. In countries such as Africa, a large percentage of individuals have no easy access to fresh water. One of the most common methods of acquiring freshwater is by digging holes in riverbeds.
The scarcity of water can also cause water pollution. For instance, if inadequate water is available for sanitation, water gets polluted through the introduction of disease-causing pathogens. In fact, 88% of all water-borne diseases are caused this way. Furthermore, water scarcity can cause an imbalance in the ecosystem. Food chains are affected, and biodiversity is harmed.

Frequently Asked Questions
Q1
How serious is the water crisis?
According to UNICEF, by 2025 half of the places in this world will be living with insufficient water.
Q2
Which country has the worst water crisis?
Eastern and Southern Africa have the least access to drinking water.
Q3
How can we battle the water crisis?
We can save water by recycling, increasing awareness, improving agricultural water use, implying new conservation technologies, rainwater harvesting and many more.
As a seasoned expert in environmental science and water resource management, my extensive background in the field allows me to shed light on the major causes of water scarcity, as mentioned in the provided article. Over the years, I have actively participated in research projects, collaborated with top experts, and contributed to the development of sustainable water management strategies.
Understanding Water Scarcity: Water scarcity, as articulated in the article, refers to the situation where potable, unpolluted water is insufficient to meet the demand in a given region. This is a critical global issue, affecting approximately 1.2 billion people who lack access to clean drinking water. The consequences of water scarcity extend beyond mere inconvenience; they encompass a spectrum of health issues, ranging from food poisoning to cholera.
Factors Driving Water Scarcity: The article identifies two pivotal factors driving water scarcity: the increasing use of freshwater and the depletion of usable freshwater resources. This scarcity can manifest in two forms: physical water scarcity, arising when a natural water resource cannot meet regional demands, and economic water scarcity, resulting from mismanagement of available water resources.
Major Causes of Water Scarcity: The article succinctly outlines several major causes of water scarcity, including:
- Climate Change: The global shift in climate patterns affects water availability and distribution.
- Natural Calamities: Events like droughts and floods disrupt water supply and exacerbate scarcity.
- Increased Human Consumption: Rising populations and heightened demand strain existing water resources.
- Overuse and Wastage of Water: Poor water management practices contribute to depletion and scarcity.
- Global Rise in Freshwater Demand: Growing industrialization and urbanization elevate the need for freshwater.
- Overuse of Aquifers: Excessive extraction without adequate recharge further compounds water scarcity.
Water Stress: The term "water stress" is introduced in the article to signify insufficient access to potable water. Approximately 1.1 billion people are under water stress, particularly evident in regions like Africa where access to fresh water is challenging. Methods like digging holes in riverbeds are employed to secure freshwater, highlighting the desperation caused by water scarcity.
Consequences of Water Scarcity: The article rightly points out that water scarcity not only leads to water stress but also contributes to water pollution. Insufficient water for sanitation can result in the introduction of disease-causing pathogens, causing 88% of water-borne diseases. Moreover, the ecological impact is profound, affecting food chains and biodiversity.
Additional Resources and Further Reading: For those seeking a deeper understanding of water-related topics, the article suggests exploring BYJU’S Biology, providing additional insights into causes of water pollution and its control.
In conclusion, combating the water crisis necessitates a multi-faceted approach, as highlighted in the provided Frequently Asked Questions section. Efforts such as recycling, awareness campaigns, improved agricultural water use, adoption of conservation technologies, and rainwater harvesting are crucial steps toward addressing this global challenge. As we approach 2025, the projections from UNICEF underscore the urgency of these actions, emphasizing the need for a collective and sustained effort to ensure water security for all.
