Thirsty Planet: The Global Water Crisis

Defining Water Scarcity

The United Nations Department of Economic and Social Affairs (UNDESA) has a way of understanding when there’s not enough water to go around. They say water scarcity happens when the needs of everyone – people, businesses, and nature – outstrip the amount of water available or its quality, given the current rules on how water is used. 

This idea of not having enough water isn’t relative. It can show up in any situation, regardless of how much water there is or how many people need it. In simple terms, if there isn’t enough water to meet the needs of all users, including the environment, we’re facing water scarcity. 

This concept is important because it highlights water scarcity as a matter of supply and demand. It’s not just about how little water there is but also about how much we need and use.

Identifying the Causes 

Water Scarcity can stem from various reasons. On one hand, it’s about how we live and what we expect from life. Fueled by wealth and habits, our lifestyles often use more water than necessary. This is a side of water scarcity shaped by society – our wants, norms, and everyday actions.

On the other hand, environmental changes also play a huge role. Climate change is altering how and when water is available. It can lead to less rain in some areas or unpredictable weather patterns, making it hard to count on a steady water supply. This shift in how nature operates means that sometimes, there’s just not enough water to go around.

Understanding Its Impacts

Although the factors shaping water scarcity differ significantly from one country to another and from one region to the next, one thing is clear: it has escalated into a global crisis. 

The 2020 Global Risk Report, published by the World Economic Forum, highlighted water scarcity as a significant global risk. It was placed among the top risks in terms of both its impact and how likely it is to happen. This emphasis on water scarcity underlines how urgent the issue has become.

Unfortunately, the impact of this crisis stretches far and wide, touching on various aspects of life and the environment. 

According to the World Health Organization, as of 2022, 2.2 billion people globally don’t have safe, clean drinking water access. Meanwhile, 3 billion don’t have essential handwashing establishments, and 4.2 billion don’t have safely managed sanitation services.

Such lack of clean water and hygiene leads to dangerous conditions and diseases that are otherwise easily avoidable, like diarrhea, typhoid, hepatitis A, and trachoma.

The water crisis affects developing nations most for a variety of reasons. Developing countries often lack the infrastructure, funding, and governance to implement proper water systems. 

Even when water is accessible, it’s often not clean. In Ethiopia, about 60% of the population doesn’t have access to drinking water, and half of those people often get contaminated water from ponds, natural springs, and hand-dug wells.

In Papua New Guinea, 87% of people don’t have a toilet, with many people defecating outside. Yet, 51% of people drink from surface water like ponds and lakes, which are more likely unsanitary.

Additionally, lack of access to clean water impacts children most – in fact, 1 in 5 deaths of children aged five and under is the result of a water-related disease. 

Women and girls are also profoundly affected, highlighting a significant gender disparity. According to Water.Org, 200 million women and girls dedicate around 200 million hours daily to collecting water. Furthermore, another 266 million spend the same amount of time searching for a place to go to meet their sanitation needs. 

The water crisis isn’t just a human issue; it also deeply affects the environment. One of the most visible impacts is on wetlands, vital ecosystems that act as nature’s water filters. According to the World Wildlife Fund (WWF), since 1900, we’ve lost half of these critical areas. Wetlands are disappearing at an alarming rate, which spells trouble for biodiversity and the natural purification of water.

One stark example of the water crisis’s environmental toll is the fate of the Aral Sea in Central Asia. Once ranked as the world’s fourth-largest freshwater lake, the Aral Sea has dramatically shrunk within just thirty years, losing an area equivalent to Lake Michigan. This drastic change is mainly due to excessive pollution and water being diverted away for farming and electricity. The lake’s salinity has skyrocketed, likening it now more to an ocean than a freshwater body. As the waters receded, they left behind polluted lands.

This ecological disaster has had severe repercussions for local communities. Food shortages have become common as the land around the Aral Sea turns barren. Public health has suffered, too, with an increase in infant mortality rates and a decrease in life expectancy.

What Actions Are Being Taken to Address Water Scarcity?

Recognizing the gravity of the situation, international organizations, governments, and NGOs are implementing various strategies to tackle water scarcity. 

The United Nations Sustainable Development Goal 6 (SDG 6) aims to ensure the availability and sustainable management of water and sanitation for all by 2030. Initiatives include:

• Increasing investment in water infrastructure is key, which includes building new water processing plants and improving existing facilities. 
• Managing watersheds more effectively ensures that natural environments can continue to play their role in storing and purifying water. 
• Ensuring that agriculture-related industries, which consume a large majority of our water supplies and other sectors, adopt practices that use water more efficiently. This could mean everything from changing how crops are irrigated to updating manufacturing processes.
• Using new technologies to tackle water scarcity. Innovations like desalination, which removes salt from seawater, making it safe for human consumption, and water recycling projects are gaining traction as ways to boost our available water supplies.

Together, these efforts represent a comprehensive approach to dealing with water scarcity. By focusing on sustainable management and innovative solutions, the goal is to combat the current crisis and secure water for future generations.

The World Wildlife Fund (WWF) is another organization deeply involved in addressing the water crisis. Besides advocating for change, the organization directly supports initiatives leading to global better water stewardship. It actively works with various organizations through the Alliance for Water Stewardship to create a worldwide standard for responsible water use. Additionally, WWF encourages the adoption of water footprinting tools in collaboration with the Water Footprint Network. It also supports critical international efforts, including the United Nations CEO Water Mandate and initiatives linked to the World Economic Forum.

A significant part of WWF’s commitment to water conservation is its efforts under the Ramsar Convention, an international treaty aimed at protecting wetlands around the globe. As a result of WWF’s dedication, over 2,000 wetlands have now been classified as Wetlands of International Importance. This classification commits countries to safeguard these critical areas from threats like development, pollution, and drainage. Due to WWF’s efforts, about 75% of these sites have been added since 1999.

WWF’s work doesn’t stop at protection; it also focuses on proactive measures to manage water resources wisely and defend natural habitats from the impending impacts of climate change. This involves advocating for climate change adaptation strategies within international conventions and emphasizing the importance of wetlands’ preservation and restoration.

How can You Help?

Individual actions play a crucial role in combating water scarcity. You can be a part of the solution with some practical steps and lifestyle adjustments. Here’s how: 

• Cut down on water waste: Be mindful of your water use daily. Simple acts like turning off the tap while brushing your teeth or choosing showers over baths can save significant amounts of water.
• Fix leaks promptly: A dripping faucet or running toilet can waste gallons of water daily. Fixing leaks in your home is an easy way to conserve water and reduce your water bill.
• Choose water-efficient appliances: When replacing household appliances like washing machines and dishwashers, look for models designed to use less water. These can drastically reduce your household water consumption over time.
• Support clean water initiatives: Many organizations are working hard to bring clean, safe water to communities worldwide that lack access. Consider donating to or volunteering with these groups to support their efforts.
• Advocate for sustainable water policies: Get involved in local and national efforts to advocate for policies and practices that promote sustainable water use and management. This could include supporting measures that protect natural water sources or promote the reuse and recycling of wastewater.
• Spread the word about water conservation: Raise awareness about saving water among your family, friends, and community. Education is a powerful tool in changing habits and fostering a culture of conservation.

You can contribute to global efforts to address water scarcity by taking these actions. Every drop counts, and your participation can help ensure we all have access to the clean, abundant water we need for future generations.

Is Clean Water in the Future For All?

Despite the disappointing state of sustainable drinking water, we’re on the right track. 

A report from the World Health Organization (WHO) and UNICEF found that since 2000, 74% of people worldwide have been using drinking water services that are considered safely managed. This statistic comes from national estimates available for 138 countries and spans four of the eight regions identified in the Sustainable Development Goals (SDGs), covering 45% of the global population.

Another report also found that the population practicing open defecation has gone from 21% to 9%, dramatically improving sanitation.

However, the same report also notes the inequalities – 8 in 10 people who live in rural areas lack access to these essential services. Of the countries able to provide estimates for different wealth groups, one in four noted that the wealthiest people are twice as likely to have access to essential water services compared to the poorest people.

It’s clear that we still have work to do. Thankfully, many charities, like UNICEF, are working on the cause. Government agencies are also helping. For example, Canada gave $40 million to the African Water Facility between 2005 and 2017. In 2020, the US gave $450 million in support of water, hygiene, and sanitation to 41 countries.

Issues of water scarcity and clean water in the future are complex, and they run the gamut from freshwater overuse in farming to matters of hygiene and sanitation. 

Achieving universal access to clean water remains an ambitious yet attainable goal. It requires concerted efforts from governments, businesses, civil society, and individuals. 

By prioritizing water sustainability, investing in infrastructure, and fostering international cooperation, we can pave the way for a future where every person has access to safe and clean water. However, realizing this vision demands unwavering commitment, innovative solutions, and collective action on a global scale.

Here’s a video from BBC Learning English about the future of water. 

Conclusion

Water scarcity poses a formidable challenge with profound implications for human health, economic development, and environmental sustainability. Addressing this complex issue requires multifaceted solutions encompassing policy interventions, technological innovations, and individual behavioral changes. 

By working together, we can ensure that future generations inherit a world where access to clean water is not a luxury but a fundamental human right. Let us seize the opportunity to safeguard our planet’s most precious resource and build a more resilient and equitable future for all.
