UN Water Video. MackinVIA. Water Is Important To Life. Water is Important for Life Some of the Earth’s water supply is temporarily locked up within the many lifeforms found across the Earth’s biosphere. This water makes up a majority of most organisms, and is a critical component, making the processes of life possible. Some organisms are made up of 95% water, while almost all the rest are more than half water. Why is water so important to life? In addition, water has the unique property of expanding as it freezes. Imagine what would happen if water became more dense? Water is Life - Water stress. Today, one of the largest concerns around the world iis the lack of freshwater for drinking and cooking. It is estimated that over one billion people, or about one-sixth of the world's population, does not have access to fresh water; of these one billion, the vast majority are living in developing nations.

Although water is one of the most common resources on the planet, only 2.5% of it can actually be consumed, and the rest is salt water. Of that 2.5%, two-thirds is confined to glaciers and permanent snow cover. Only a fraction of the world's water is liquid freshwater, and it is increasingly the subject of conflict and strife as it becomes less available.

Figure 1. Population Growth The world's population is growing at a rate of 80 million people each year. A country is said to experience "water stress" when annual water supplies drop below 1,700 cubic meters per person. Figure 2. As of 1999, 31 countries, with a total of 500 million people, faced either water stress or water scarcity. 1 Water - its importance and source. 1.1 The importance of water Water is one of the most important substances on earth. All plants and animals must have water to survive. If there was no water there would be no life on earth. Fig. 6.1: Plants and animals need water. Apart from drinking it to survive, people have many other uses for water. These include: cooking washing their bodies washing clothes washing cooking and eating utensils; such as billies, saucepans, crockery and cutlery keeping houses and communities clean recreation; such as swimming pools keeping plants alive in gardens and parks Water is also essential for the healthy growth of farm crops and farm stock and is used in the manufacture of many products.

Fig. 6.2: Some domestic uses of water. It is most important that the water which people drink and use for other purposes is clean water. Water that is safe for drinking is called potable water. Disease-causing germs and chemicals can find their way into water supplies. Top of Page 1.2 Sources of water Surface water.

Health and Sanitation Diseases from unsafe water and lack of basic sanitation kill more people every year than all forms of violence, including war. Children are especially vulnerable, as their bodies aren't strong enough to fight diarrhea, dysentery and other illnesses. With basic education about proper sanitation, such as hand-washing and the use of latrines, many fatal diseases can be avoided. Women and Children The work of collecting water usually falls to the women and children of the family. Many have to spend up to 4 hours each day walking to the nearest water source to provide their family with enough water for the day. Often, the water that they collect is contaminated with germs that can cause very serious illnesses or even death.

The time that is spent walking to collect water is not only a dangerous time for them, but is also time that is not spent learning to read and write, making an income, or caring for the younger children in the family.

This will help us reach our target of $40,000, the amount we need to get a Melanesian WASH project off the ground. By working together the Kiwi water sector can make a real difference to the lives of communities that are forced to drink dirty water every day.

How it works We want companies both large and small to dive in deep. By signing up, your organisation will pledge to raise $2,000. The challenge day The Oxfam Water Challenge day will bring together workmates to design, build, present and deconstruct a solution to our challenge. The challenge will be based on a water problem/scenario, with design, engineering and pitching/presenting skills needed. The prize There will be two winners!

Safe water in Melanesia. UNICEF NZ Children's Charity | Helping Children Survive & Thrive. Click images to enlarge Clean water is collected from a hand pump, for drinking and washing. This simple pump literally changes lives. © UNICEF/Pirozzi “Since we have had the wells our children are much healthier and they are not falling sick as often,” says Omar Mshindo Bakari of Pemba, Tanzania.

The UNICEF project focused on providing personal hygiene training in villages, building wells and rain water harvesting systems and toileting and handwashing facilities, and training for the community on how to maintain their new water and toilet systems so they could be self sufficient. Kisesa Health Centre was one of many community facilities to receive a rainwater harvesting tank.

Ogho Primary School also received a rainwater harvesting tank and 10 new toilets. Thank you This project was fully funded by Kiwi donors in 2009, with matching donations from Gareth and Jo Morgan.

Clean Water for All. 5 Global Kids' Health Issues Huge progress has been made in many critical areas involving children's health. Yet there is still important work to be done, and most of it doesn't involve expensive new drugs or surgical procedures. Instead, it's about the basics that most of us take for granted. We have identified 5 issues that desperately need the world's attention for the sake of children and their families, and suggest some ways that you and your family can help.

In most parts of the world, we take clean running water for granted. Every 21 seconds, a child dies from a water-related illness. UNICEF reports that more than 5,000 children under age 5 die each day because of diarrheal diseases, often contracted through contaminated drinking water or no access to sanitation facilities, like bathrooms with flushable toilets. Again, the impact of this is felt keenly by children. This cycle of disease, joblessness, and missed school makes the water crisis a major part of global poverty.

Every day in rural communities and poor urban centers throughout sub-Saharan Africa, hundreds of millions of people suffer from a lack of access to clean, safe water. Women and girls especially bear the burden of walking miles at a time to gather water from streams and ponds - full of water-borne disease that is making them and their families sick. Illness from drinking dirty water and the time lost fetching it robs entire communities of their futures. Hope is put on hold in over half of the developing world's primary schools without access to water and sanitation. It left us wondering why.

Water Scarcity Map | Water Shortage in the World | Growing Blue™ Tool. US – Sustainability Originating from rain or snow, available precipitation refers to water that is actually usable. Today, many of the United States’ fresh water aquifers are either stressed or negatively impacted by over pumping. Still, others are impacted by intrusion from salt water.

As an example, in Houston, extensive pumpage of ground water to support economic and population growth has caused water level declines of approximately 400 feet and resulted in subsidence. The country’s growth depends on using its water resources in sustainable ways – ways that preserve a supply necessary for sustaining quality of life, economic investment and ecosystem health. On the whole, sustainable water management involves meeting the needs of today’s population while taking into account the needs of future generations. The more we use water, the more we influence its quality. On a local level, water cycles are also influenced by the way we plan our cities.
