SUMMARY MARCH 28 WATER CRISIS

Water Crisis
While the world's population tripled in the 20th century, the use of renewable water resources has grown six-fold. Within the next fifty years, the world population will increase by another 40 to 50 %. This population growth - coupled with industrialization and urbanization - will result in an increasing demand for water and will have serious consequences on the environment.

People lack drinking water and sanitation

Already there is more waste water generated and dispersed today than at any other time in the history of our planet: more than one out of six people lack access to safe drinking water, namely 1.1 billion people, and more than two out of six lack adequate sanitation, namely 2.6 billion people (Estimation for 2002, by theWHO/UNICEF JMP, 2004). 3900 children die every day from water borne diseases (WHO 2004). One must know that these figures represent only people with very poor conditions. In reality, these figures should be much higher. 
  
Water resources are becoming scarce

Agricultural crisis

Although food security has been significantly increased in the past thirty years, water withdrawals for irrigation represent 66 % of the total withdrawals and up to 90 % in arid regions, the other 34 % being used by domestic households (10 %), industry (20 %), or evaporated from reservoirs (4 %). (Source: Shiklomanov, 1999)

As the per capita use increases due to changes in lifestyle and as population increases as well, the proportion of water for human use is increasing. This, coupled with spatial and temporal variations in water availability, means that the water to produce food for human consumption, industrial processes and all the other uses is becoming scarce.

Environmental crisis

It is all the more critical that increased water use by humans does not only reduce the amount of water available for industrial and agricultural development but has a profound effect on aquatic ecosystems and their dependent species. Environmental balances are disturbed and cannot play their regulating role anymore. (See Water and Nature)


The concept of Water Stress
Source: WaterGAP 2.0 - December 1999

Water stress results from an imbalance between water use and water resources. The water stress indicator in this map measures the proportion of water withdrawal with respect to total renewable resources. It is a criticality ratio, which implies that water stress depends on the variability of resources. Water stress causes deterioration of fresh water resources in terms of quantity (aquifer over-exploitation, dry rivers, etc.) and quality (eutrophication, organic matter pollution, saline intrusion, etc.) The value of this criticality ratio that indicates high water stress is based on expert judgment and experience (Alcamo and others, 1999). It ranges between 20 % for basins with highly variable runoff and 60 % for temperate zone basins. In this map, we take an overall value of 40 % to indicate high water stress. We see that the situation is heterogeneous over the world.

An increase in tensions

As the resource is becoming scarce, tensions among different users may intensify, both at the national and international level. Over 260 river basins are shared by two or more countries. In the absence of strong institutions and agreements, changes within a basin can lead to transboundary tensions. When major projects proceed without regional collaboration, they can become a point of conflicts, heightening regional instability. The Parana La Plata, the Aral Sea, the Jordan and the Danube may serve as examples. Due to the pressure on the Aral Sea, half of its superficy has disappeared, representing 2/3 of its volume. 36 000 km2 of marin grounds are now recovered by salt.


Towards a way to impove the situation

"There is a water crisis today. But the crisis is not about having too little water to satisfy our needs. It is a crisis of managing water so badly that billions of people - and the environment - suffer badly."  World Water Vision Report
  
With the current state of affairs, correcting measures still can be taken to avoid the crisis to be worsening. There is a increasing awareness that our freshwater resources are limited and need to be protected both in terms of quantity and quality. This water challenge affects not only the water community, but also decision-makers and every human being."Water is everybody's business" was one the the key messages of the 2nd World Water Forum.

Saving water resources

Whatever the use of freshwater (agriculture, industry, domestic use), huge saving of water and improving of water management is possible. Almost everywhere, water is wasted, and as long as people are not facing water scarcity, they believe access to water is an obvious and natural thing. With urbanization and changes in lifestyle, water consumption is bound to increase. However, changes in food habits, for example, may reduce the problem, knowing that growing 1kg of potatoes requires only 100 litres of water, whereas 1 kg of beef requires 13 000 litres.

Improving drinking water supply

Water should be recognized as a great priority. One of the main objectives of the World Water Council is to increase awareness of the water issue. Decision-makers at all levels must be implicated. One of the Millenium Development Goals is to halve, by 2015, the proportion of people without sustainable access to safe drinking water and sanitation. To that aim, several measures should be taken:
  • guarantee the right to water;
  • decentralise the responsibility for water;
  • develop know-how at the local level;
  • increase and improve financing;
  • evaluate and monitor water resources.
Improving transboundary cooperation

As far as transboundary conflicts are concerned, regional economic developement and cultural preservation can all be strengthened by states cooperating of water. Instead of a trend towards war, water management can be viewed as a trend towards cooperation and peace. Many initiatives are launched to avoid crises. Institutional commitments like in the Senegal River are created. In 2001, Unesco and Grenn Cross International have joined forces in response to the growing threat of conflicts linked to water. They launched the joint From Potential Conflicts to Co-Operation Potential programme to promote peace in the use of transboundary watercourses by addressing conflicts and fostering co-operation among states and stakeholders.

Due to the pressure on the Aral Sea, half of its superficy has disappeared, representing 2/3 of its volume. 36 000 km2 of marin grounds are now recovered by salt.

    A way to INCREASE the situation is a RAISING awareness that our freshwater resources are limited and need to be protected both in terms of quantity and quality.” Water is everybody's business" was one the the key messages of the 2nd World Water Forum.

    For saving water resources the use of freshwater (agriculture, industry, domestic use), LOTS saving of water and INCREASE of water management is possible. Changes in food habits, for example, may DECREASE the problem, knowing that IMPROVE 1kg of potatoes requires only 100 litres of water, whereas 1 kg of beef requires 13 000 litres.

    To INCREASE drinking water supply several measures should be taken for the improvement of water: guarantee the right to water; decentralise the responsibility for water; develop know-how at the local level; increase and improve financing; evaluate and monitor water resources.

  5. Water Crisis


    The use of renewable water resources has grown 6 times. In the next 50 years is estimated the population to increase 40%, this, along with industrialization and urbanization leads to a demand for water that will cause consequences.

    People Lack drinking water and sanitation.
    Already more wastewater generated, still, more than 1 in 10 people lack access to clean water. 2.6 billion people lack adequate sanitation and 3900 children die every day from water-related diseases and this is just poor people, guess how many are in total?

    Water resources are becoming scarce
    Agricultural Crisis
    As per capita consumption increases due to changes in lifestyle, and as the population increases, the proportion of water for human use increases, this, with variations in water availability, which is that water needed to produce food, Industrial Processes are becoming scarce.

    Environmental crisis.
    Increase water use in humans, reduces the availability of water for industrial development and has an impact on the systems and aquatic sea life.
    Water stress results from an imbalance between water and its resources; this causes a decline in this, in terms of quantity= over-exploitation, dry rivers. And quality:= eutrophicaton, Pollution, saline intrusion.

    An Increase in Tensions
    As water becomes more scarce, tensions developed between different consumers, both nationally and internationally. Over 260 river basins are shared by 2 or more countries, this can lead to border tensions.

    Towards a way to improve the situation.
    The correction measures can be taken to avoid worsening the crisis. The water resources are limited, so they must be protected, "water is everybody's business"

    Saving water resources
    In almost all countries the water is wasted. Thanks to this and many other reasons water consume is increasing.

    Improving drinking water supply.
    water should be recognized as a huge priority, so one of the Millennium Development Goals is to halve the people that Lack access to safe drinking water and sanitation. These are the measures to be taken:
    -guarantee the right to water
    -develop local knowledge
    -Improve financing
    -manage water resources.

    In the 20th century the world’s population had increased by the triple and the renewable water resources had six-folded. On the next 50 years the population is going to increase by 40 or 50 percent more so we need to take care of water. In the world 1.1 billion of people lack of safe water and 2.6 billion of people lack of safe sanitation. In the world 3900 children die each day because of water borne deseases. The pas thirty years water withdrawals for irrigation represent 66% of total withdrawals and up to 90% in arid regions, the other 34% being used by domestic households (10%) , industry (20%) , or evaporated from reservoirs (4%). It more critical the water for human use and not only because it reduces the amount of agricultural and industrial ecosystems but also because it causes a profound effect on aquatic ecosystems. Because of the scarce of water more than 260 rivers and basins are being shared between countries. Part of the Aral sea has been loosed because the 2/3 of the Aral sea of marin grounds are recovered with salt. We humans need to save water as much as possible because people are not facing water scarcity. One solution could be changing the food habits for example 1 kg of potatoes consume 100 liters of water and 1 kg of beef requires 13000 liters of water. Water should be recognized as a great priority because one the millennium development goals is to halve the proportion of people without sustainable access to safe water drinking in the 2015. To that aim several measures should be taken:
    • Guarantee the the right to water.
    • Decentralize the responsibility of water.
    • Develop know-how at the local level.
    • Increase and improve financing.

In 2001, Unesco and Grenn Cross International have joined forces in response to the growing threat of conflicts linked to water. They launched the joint From Potential Conflicts to Co-Operation Potential programme to promote peace in the use of transboundary watercourses by addressing conflicts and fostering co-operation among states and stakeholders.

  13. In the 20th century the world’s population had increased. On the next 50 years the population is going to increase by 40 or 50 percent more.

    1.1 billion of people lack of safe water and 2.6 billion of people lack of safe sanitation. Children die each day because of water borne deseases.

    The water for human use and not only because it reduces the amount of agricultural and industrial ecosystems but also because it causes a profound effect on aquatic ecosystems. Because of the scarce of water more than 260 rivers and basins are being shared between countries.

    One solution could be changing the food habits for example 1 kg of potatoes consume 100 liters of water and 1 kg of beef requires 13000 liters of water. To that aim several measures should be taken.

    Already there is waster water generated and dispersed today than at any other time in the history of our planet. 3900 children die every day from water borne. One must know that these figures represent only people with very poor conditions. In reality, these figures should be much higher.

    Water resources are becoming scarce

    Agricultural crisis

    Water withdrawals for irrigation represent 66 % of the total withdrawals and up to 90 % in arid regions, the other 34 % being used by domestic households (10 %), industry (20 %), or evaporated from reservoirs (4 %).

    As population increases, the proportion of water for human use is increasing, means that the water to produce food for human consumption, industrial processes and all the other uses is becoming scarce.

    Environmental crisis

    Increased water use by humans does not only reduce the amount of water available, but has a profound effect on aquatic ecosystems and their species.

    The concept of Water Stress

    Water stress results from an imbalance between water use and water resources. The water stress indicator measures the proportion of water withdrawal with respect to total renewable resources. Which implies that water stress depends on the variability of resources. Water stress causes deterioration of fresh water resources in terms of quantity and quality. The value of this criticality ratio is based on expert judgment and experience. It ranges between 20 % for basins with highly variable runoff and 60 % for temperate zone basins.

    An increase in tensions

    Tensions among different users may intensify, both at the national and international level. Over 260 river basins are shared by two or more countries. In the absence of strong institutions and agreements, changes within a basin can lead to trans boundary tensions. Due to the pressure on the Aral Sea, half of its superficies has disappeared,

    Food and Agriculture Organization said in 2003 that there is no water crisis but steps must be taken to avoid one in the future. The major aspects of the water crisis are allegedly overall scarcity of usable water and water pollution.
    There are many children who do not have the opportunity you have to gain resources easily such as food, clothing, utensils, but most important is water. The humans has every right to use water as a source of life as it is necessary for the survival, but this is being applied worldwide. The Sanitation is important for people to have good condition of this usage and for their own wealth. This situation over the World needs to change now, so all of us need to accomplish with this entire people to give a well supplies to this water usage and to use it in a good way, so what are you waiting for, stand up and take action.

    It is all the more critical that increased water use by humans does not only reduce the amount of water available for industrial and agricultural development but has a profound effect on aquatic ecosystems and their dependent species.

    In the world is more salt water than fresh water so this means that in few years we have to take some salt water because we are wasted water all the time that we have to look some solutions like makings campaings.


    Almost everywhere, water is wasted, and as long as people are not facing water scarcity, they believe access to water is an obvious and natural thing. With urbanization and changes in lifestyle, water consumption is bound to increase.

    The solution is to know that we have the right to have water , make a union that take some strict decisions like a managment with cooperation , peace.

  23. Water crisis
    People in the only think in one thing. If I have money it doesn’t matter if I spend water. They throw it away, they don’t use it well. Only a little part of all the water in the worlds is fresh, around 1.1 percent is the one that we could use for our needs. We need it to live. In Colombia there is a big amount of water, we are rich in this case. We are near the Pacific Ocean. But! There are lots of countries that doesn’t have these big pleasure of washing themselves every day and if we want two or three times. Some countries like Egypt, Bangladesh, Libya, Ethiopia and lots more don’t have the satisfaction we have.
    There are lots of places where people need to wash themselves only two or three days per week or maybe for month. Some people need to use the same water that animals use to wash them and to do their necessities. Some people wash themselves with the urine of animals. People drink dirty water some moms need to leave their kids alone and walk lots of miles to look for a little bit of water.
    We need to save water, it is important because this water that we are throwing could help lots of people who die because of these. Colombia is a country reach in water resources so it doesn’t matter if we throw it away. So let’s be conscious and lets hel people who need it. Maybe sometime we will need their help.

Which reminds him how quickly things can change in television and how lucky he’s been to be one of television’s steadiest stars, with a decade logged on the now-ending “Smallville.”
    The 34 year old actor said that It can all go away and can go fast,” eventhrough he has played Clark Kent for 10 season Welling refused several times to be Superman in movies for example Superman Returns (with Brandon routh). At the beginig he dint loved the idea of becoming superman cause that red-and-blue costume, the same one that brought success to actors such as Christopher Reeve and George Reeves in previous decades but came with a smothering career cost, after they flew across the sky in the public imagination they were locked into the image. When Welling found out the new show had the motto of “no tights, no flights,” he was far more intrigued. During the fourth season of the show, Welling had learned so much on the set that he got a new ambition — directing. He did just that in the fifth season and another one of his efforts was the Booster Gold episode that aired with great fanfare recently. Even before Welling was directing, he was “a leader” on the set. He states that Smallville help create his life and that he is proud of what will the show become after it ends, a legacy.

    MEANWHILE EARTH´S HABITANTS HAD GROW 3 TIMES IN THE LAST century, the use of renewable H2O has RAISED SIX TIMES. Already there EXIST more DIRTY H2O MADE and SPREADED IN THIS DAYS than at any other PERIOD in the history of EARTH. As PER HEAD use RAIDE UP BECAUSE OF changes in lifestyle and as THE NUMBER OF PEOPLE LIVING IN A PLACE GROW TOO, the RATIO of H2O IMPLEMENTED by PEOPLE does nor only DICREASSE the QUANTITY of H2O available for industrial and agricultural GROWTH but has a HUGE CONSECUENCE on WATER ecosystems and their dependent ECOSYSTEM. With the PRESENT state of affairs, correcting METHODS still can be taken to PREVENT the PROBLEM to INCREASE. There is a increasing PREOCUPATION that our PURE H2O are VERY LITTLE and IT IS NECESSARY to be protected in both terms of quantity and quality. WHICHEVER the use of SAFE H2O GREAT saving of H2O and improving of H2O USAGE is possible. As far as transboundary PROBLMES are concerned, LOCAL economic PROGRESS and cultural preservation can all be REINFORCED by states cooperating of H2O.

    The use of renewable water resources has grown 6 times. In the next 50 years is estimated the population to increase 40%, this, along with industrialization and urbanization leads to a demand for water that will cause consequences.

    Already more wastewater generated, still, more than 1 in 10 people lack access to clean water. 2.6 billion people lack adequate sanitation and 3900 children die every day from water-related diseases and this is just poor people, guess how many are in total?

    Water resources are becoming scarce
    Agricultural Crisis
    As per capita consumption increases due to changes in lifestyle, and as the population increases, the proportion of water for human use increases, this, with variations in water availability, which is that water needed to produce food, Industrial Processes are becoming scarce.

    Increase water use in humans, reduces the availability of water for industrial development and has an impact on the systems and aquatic sea life.
    Water stress results from an imbalance between water and its resources; this causes a decline in this, in terms of quantity= over-exploitation, dry rivers. And quality:= eutrophicaton, Pollution, saline intrusion.

    An Increase in Tensions
    As water becomes more scarce, tensions developed between different consumers, both nationally and internationally. Over 260 river basins are shared by 2 or more countries, this can lead to border tensions.

    Towards a way to improve the situation.
    The correction measures can be taken to avoid worsening the crisis. The water resources are limited, so they must be protected, "water is everybody's business"

    Saving water resources
    In almost all countries the water is wasted. Thanks to this and many other reasons water consume is increasing.

    Improving drinking water supply.
    water should be recognized as a huge priority, so one of the Millennium Development Goals is to halve the people that Lack access to safe drinking water and sanitation. These are the measures to be taken:
    -guarantee the right to water
    -develop local knowledge
    -Improve financing
    -manage water resources.

  31. Water Crisis
    "There is a water crisis today. But the crisis is not about having too little water to satisfy our needs. It is a crisis of managing water so badly that billions of people - and the environment - suffer badly."
    World Water Vision Report

    While the world's population tripled in the 20th century, the use of renewable water resources has grown six-fold with a result in an increasing demand for water ,will have serious consequences on the environment.
    Already there is more waste water generated and dispersed today than at any other time in the history of our planet, besides 3900 children die every day from water borne diseases.

    Although food security has been significantly increased in the past thirty years, water withdrawals for irrigation represent 66 % of the total withdrawals and up to 90 % in arid regions. As the per capita use increases due to changes in lifestyle and as population increases as well, the proportion of water for human use is increasing. This, coupled with spatial and temporal variations in water availability, means that the water to produce food for human consumption, industrial processes and all the other uses is becoming scarce.Increased water use by humans has a profound effect on aquatic ecosystems and their dependent species.

    Water stress results from an imbalance between water use and water resources. The water stress indicator in this map measures the proportion of water withdrawal with respect to total renewable resources. It is a criticality ratio, which implies that water stress depends on the variability of resources.


    As the resource is becoming scarce, tensions among different users may intensify, both at the national and i nternational level. Over 260 river basins are shared by two or more countries. There is a increasing awareness that our freshwater resources are limited and need to be protected both in terms of quantity and quality.
    Whatever the use of freshwater (agriculture, industry, domestic use), huge saving of water and improving of water management is possible.
    Water should be recognized as a great priority.. One of the Millenium Development Goals is to halve, by 2015, the proportion of people without sustainable access to safe drinking water and sanitation. To that aim, several measures should be taken:
    • guarantee the right to water;
    • decentralise the responsibility for water;
    • develop know-how at the local level;
    • increase and improve financing;
    • evaluate and monitor water resources.

    As far as transboundary conflicts are concerned, regional economic developement and cultural preservation can all be strengthened by states cooperating of water. Instead of a trend towards war, water management can be viewed as a trend towards cooperation and peace.
