Many countries throughout the world live without access to safe, clean water. Safe water is crucial to one's health - without it, people are more at risk to infectious diseases and even premature death. More than 840,000 people die every year from water-related illnesses.

By 2025, it's estimated that a staggering 1.8 billion people will live in areas facing water shortage, according to National Geographic.

Getting any kind of access to water is difficult for many countries - women living near the Sahara desert in Africa and in some parts of southern Asia have to walk an average of 3.7 miles to collect clean water. World Water Day, hosted on March 22, helps serve as an important reminder of the struggles that countries are facing just to have clean, drinkable water. Here are some images showing how people around the world collect their water:

Over 1.4 million people have fled their homes in Yemen and are now struggling to find food and water. Oxfam teams in Yemen are helping by providing tanks of clean drinking water to internally displaced people and through direct cash payments which allow families to buy food and basic supplies.

Since the beginning of the current conflict women and children have had to walk long distances just to collect a few litres of water for their families. We are helping by providing internally displaced people with 7.5 litres of water per person per day.

Cars wait for fuel in Al Hasaba district, in Sana'a, the capital of Yemen. The oil crisis has escalated as a result of the conflict and siege imposed on Yemen.

The oil crisis has also worsened the food shortages because farmers are unable to pump water to their fields. Oxfam is providing direct cash payments to families which allow them to buy food and basic supplies.

In Sana'a, a boy stands on top of a water truck while other children and women wait to collect water for their families.

Yemenis have suffered with the lack of water due to the increasing prices of water tanks, which are now the main source of water. To help people meet their basic needs, we have provided water tanks and clean drinking water to thousands of internally displaced people.

Families who fled their homes after air strikes in Haradd wait in turn for their share of water from an Oxfam water tank in the Shafar district (Hajja).

Oxfam worker and locals help to install a water tank which now provides clean water to a camp of internally displaced people in the Huth district, Amran. We are trying to cover the water needs of 2,975 internally displaced people as well as the host communities.

Climate change will likely change many aspects of life on Earth, including making access to clean water a big problem. From drought to sea-level rise, climate change is threatening to leave us all thirsty.

For the drought-stricken residents of San Diego County, California, relief may soon be in sight: Construction is under way on a new seawater desalination plant - a plant that removes the salt from seawater - which will produce 50 million gallons of drinkable water every day. According to the MIT Technology Review, it's the largest such plant in the Western Hemisphere.

The plant, which is being built in the city of Carlsbad, is the newest effort to address the region's pressing water needs. California just entered its fourth year of drought, and 40% of the state is listed as suffering from "exceptional drought," the most severe classification on the US Drought Monitor.

Drought is expected to become an even fiercer challenge in the future as climate change drives temperatures higher - not just in California, but around the world. Climate change has the potential to seriously affect some regions' water resources, and drought is just one way that can happen.

Sea-level rise is also threatening coastal water supplies, which often draw their freshwater from underground aquifers. As the ocean creeps further inland, it can invade these aquifers and contaminate the groundwater.

With these threats to freshwater sources, finding new and better ways to produce drinkable water is a growing concern. The ocean is the biggest source of water on the planet, but undrinkable because of its high salt content. Luckily scientists have come up with a handful of ways to get the salt out of water and make it safe for drinking, and they're working on developing more.

Unfortunately, desalination by any method is expensive and, for the time being, not practical for every water-scarce community. The Carlsbad plant, for instance, is costing $1 billion to build, according to the MIT Technology Review. But scientists are working on improving existing techniques to make them more efficient and less costly.

Here are some of the desalination techniques they've come up with so far:
Distillation
Distilling water is the oldest and most common method used to remove salt. In simple terms, distillation involves evaporating the water, and then condensing it back into a liquid. The salt will stay behind when the water boils into the air, and the clean water can then be collected in a separate container.

You can actually conduct a simplistic version of this process in your own home by constructing a "solar still." You stretch a sheet of clear plastic over the bowl or hole that contains the contaminated water.

The sun will shine through the plastic, warming the water below and causing it to slowly vaporize, leaving salt and other contaminants behind. The evaporated water will condense on the underside of the plastic sheet, where you can then collect it in a separate container.

It looks kind of like this:

Distillation plants perform this basic scientific process on a much larger scale, but they run on electricity to speed up the process.

In addition, electric household distillers exist and can be purchased for anywhere from less than $100 to thousands of dollars, depending on the size and efficiency of the device. However, most of these can only produce a few gallons of clean water at a time, and in general the process of distillation requires a lot of energy.
Reverse osmosis
This is one of the most common methods used in desalination plants today, and is the method that will be used at the Carlsbad plant in San Diego County.

The technique uses high-pressure pumps to force contaminated water across a special membrane, which weeds out the bad stuff and lets the pure water through.

Recently, scientists have been investigating a new type of membrane that will make it easier to push the water through. The experimental method uses graphene, and researchers at MIT have managed to create a super-thin graphene membrane just one atom thick, which they say will make reverse osmosis easier, less energy-intensive, and cheaper.

While reverse osmosis is touted as a cheaper, lower-energy alternative to large-scale distillation, Carlsbad's $1 billion construction project is a reminder that such plants still may not be practical for every water-scarce community.

And annual operations and management costs can be crippling, as well as highly variable depending on the size of the plant and the systems used to take in water and distribute it to customers. For example, a report from Pacific Institute found that the Kwinana desalination plant in Perth, Australia operates at about $17 million per year, and the Gold Coast desalination plant in Tugun, Australia requires $30 million per year.

This method relies on the natural process of osmosis, which is water's tendency to flow from areas with a high concentration of a solute (like salt) to areas with a lower concentration.

Let's say you have two containers, separated by a membrane that allows water to pass through (but shuts out other substances, like salt).

You fill one side with pure water and the other side with saltwater. The pure water will start to flow across the membrane into the saltwater side in an effort to restore balance.

Forward osmosis relies on a similar system, and it doesn't require the high-pressure pumps that reverse osmosis uses. It separates two containers with a membrane - on one side is the contaminated water, and on the other side is water with a very high concentration of some kind of solute, usually salt. Water from the contaminated side will start to flow across the membrane, diluting the salt solution on the other side.

But there are some hang-ups. Even though the pure water flowing across the membrane dilutes the concentrated saltwater, it doesn't eliminate the salt. So forward osmosis is a good way to get rid of a wide range of contaminants that might be in the water, since the membrane will weed them out - but you still end up with saltwater on the other side, meaning you must go through an additional desalination step at the end to totally purify the water.

Compared to reverse osmosis, it's a new technology. Water technology company Modern Water opened the first commercial forward osmosis plan in Al Khaluf, Oman, in 2010, and they opened a second plant in Al Najdah in 2012.

Advocates say the process is better at weeding out contaminants (aside from salt) than reverse osmosis. Some have also hailed the process because it seems to use less energy. Modern Water reported that its Al Khaluf plant showed a 47% reduction in energy use compared to reverse osmosis. But it's unclear whether the technology, as a whole, really is more efficient. A study from MIT found that forward osmosis is actually less energy-efficient than reverse osmosis.
Electrodialysis
Electrodialysis is kind of the opposite of osmosis. Rather than moving water across a membrane, electrodialysis moves particles in the water across the membrane by drawing them out with an electric charge. Salt, for example, is composed of charged ions that will break apart and move when an electric charge is applied to them.

While this works well on salt, it doesn't really help to weed out other contaminants that might be found in seawater, like dirt or microscopic organisms. But since electrodialysis tends to work faster and can desalinate larger quantities of water than other methods, researchers are working on ways to make the process better at eliminating other contaminants.

New developments may be in the works, but electrodialysis, as a water-purification technology, has been around for decades. There are actually electrodialysis plants around the world, according to Desalination: Trends and Technologies, a 2011 book edited by Michael Schorr, on desalination. These include the US, Canada, Iran, and parts of Europe.
A look ahead
Desalination may be costly and energy-intensive no matter what technology you're looking at. But as water scarcity grows around the world, it may become a necessary option for more communities.

Some countries are already investing heavily in the technology. Pacific Institute reports that Australia invested in six new desalination plants between 2006 and 2012. But the Institute warns that the technology has a long way to go before it can be a truly viable solution for the future.

Between high costs, high energy use, and even the possibility of environmental destruction - seawater treatment plants can accidentally take in and kill small marine animals - continued research is needed to make the technology safer and more efficient. In time, perhaps it could become one of our most important options in avoiding a parched and thirsty future.
