Droughts in\u00a0Somalia. Water rationing in Rome.\u00a0Flooding in Jakarta\u00a0and\u00a0Harvey-battered Houston. It doesn’t take a hydrologist to realize that there is a growing global water crisis.<\/em><\/p>\n

\"\"<\/a><\/p>\n

Each August, water experts, industry innovators, and researchers gather in Stockholm for\u00a0World Water Week\u00a0to tackle the planet’s most pressing water issues.<\/p>\n

What are they up against this year? Here’s a quick rundown on the growing global water crisis.<\/p>\n

1) We’re Changing the Climate, Making Dry Areas Drier and Precipitation More Variable and Extreme.<\/h2>\n

Climate change is warming the planet, making the world’s hottest geographies even more scorching. At the same time, clouds are moving away from the equator toward the poles, due to a climate-change driven phenomenon called Hadley Cell expansion. This deprives equatorial regions like sub-Saharan Africa, the Middle East and Central America of life-giving rainwater.<\/p>\n

\"\"<\/a><\/p>\n

Paradoxically, climate change is also increasing precipitation in other areas, and people who live near rivers and streams have the most to lose. Currently, at least 21 million people worldwide are at risk of river flooding each year. That number could increase to\u00a054 million by 2030. All countries with the greatest exposure to river floods are least developed or developing countries \u2013 which makes them even more vulnerable to climate change and natural disasters. This summer, extreme flooding submerged over a third of Bangladesh,\u00a0claiming over 115 lives and affecting 5.7 million citizens.<\/p>\n

2) More People + More Money = More Water Demand.<\/h2>\n

It’s a simple equation: As populations increase and incomes grow, so does water demand. The world’s population, now at 7.5 billion, is projected to\u00a0add 2.3 billion more people by 2050. How can the planet satisfy their thirst? Growing incomes also exacerbate the water problem, because of the water-intensive products\u2014like\u00a0meat\u00a0and\u00a0energy from fossil fuels\u2014that richer populations demand.<\/p>\n

3) Groundwater Is Being Depleted.<\/h2>\n

About 30 percent of Earth’s fresh water lies deep underground in aquifers. And it’s extracted daily for farming, drinking and industrial processes \u2013 often at dangerously unsustainable rates. Nowhere is this more evident than India, which\u00a0guzzles more groundwater than any other country.\u00a054 percent\u00a0of India’s groundwater wells are decreasing, meaning that water is used faster than it’s replenished. Unless patterns shift, in 20 years,\u00a060 percent\u00a0of India’s aquifers will be in critical condition.<\/p>\n

\"\"<\/a><\/p>\n

Unlike an incoming hurricane or a drained lake, the naked eye cannot see when groundwater reserves in aquifers are declining. Global water supplies are susceptible to this hidden and growing threat.<\/p>\n

4) Water Infrastructure Is in a Dismal State of Disrepair.<\/h2>\n

Having enough water to go around is only the beginning. That water also needs to be transported, treated, and discharged. Around the world, water infrastructure\u2015treatment plants, pipes, and sewer systems\u2015is in a state of disrepair. In the United States,\u00a06 billion gallons of treated water are lost per day\u00a0from leaky pipes alone. Built infrastructure is notoriously expensive to install and repair, meaning that many localities ignore growing infrastructure issues until disaster strikes, as it did in\u00a0California\u00a0earlier this year.<\/p>\n

5) And Natural Infrastructure Is Being Ignored.<\/h2>\n

Healthy ecosystems are ”\u00a0natural infrastructure” and vital to clean, plentiful water. They filter pollutants, buffer against floods and storms, and regulate water supply. Plants and trees are essential for replenishing groundwater; without them, rainfall will slide across dry land, instead of seeping into the soil. Loss of vegetation from deforestation, overgrazing and urbanization is limiting our natural infrastructure and the benefits that it provides. Forested watersheds around the world are under threat:\u00a0watersheds have lost up to 22 percent of their forests in the past 14 years.<\/p>\n

6) Water Is Wasted.<\/h2>\n

Although it’s true that water is a renewable resource, it’s often wasted. Inefficient practices like flood irrigation and\u00a0water-intensive wet cooling at thermal power plants\u00a0use more water than necessary. What’s more, as we pollute our available water at an alarming rate, we also fail to treat it. About\u00a080 percent\u00a0of the world’s wastewater is discharged back into nature without further treatment or reuse. In\u00a0many countries, it’s cheaper to receive clean drinking water than to treat and dispose of wastewater, which encourages water waste. This brings us to the next issue:<\/p>\n

7) The Price Is Wrong.<\/h2>\n

Globally, water is seriously undervalued. Its price does not reflect the true, total cost of service, from its transport via infrastructure to its treatment and disposal. This has led to misallocation of water, and a lack of investments in infrastructure and new water technologies that use water more efficiently. After all, why would a company or government invest in expensive water-saving technologies, when water is cheaper than the technology in question? When the price of receiving clean water is closer to its actual service cost,\u00a0efficient water use will be incentivized. And on the flip side, the poor often end up paying\u00a0disproportionately high prices\u00a0for water, stunting development.<\/p>\n

It’s Not Too Late<\/h2>\n

Amidst these seven deadly water sins, there is good news: governments, businesses, universities and citizens around the world are waking up to water challenges, and beginning to take action. Each year brings more solutions \u2013 like using wastewater for energy, using restoration to bring water back to dry topographies, and monitoring groundwater levels more closely. However, even the best solutions will not implement themselves. Along with fresh water, political will and public pressure are critical resources in ensuring a sustainable future for all.<\/p>\n
