The rate at which foods heat up in water or oil is affected by the way hot liquid circulates.

 From natural systems to deal with surface water run off and pollution to green corridors to increasing interest in urban food production,

and monitored to meet the unique needs of each city for food production, water use, nutrient recycling, and habitat.

and water requirements of such urban landscapes in these arid areas is called xeriscaping oe a concept that has received so-far mixed responses in terms of public acceptance.

because xeriscaping is justified more by reducing landscaping costs oe in this case water costs oe than by providing desired benefits like recreation, pollution mitigation,

New technologies for treating wastewater for example, look less like industrial treatment plants and more like ecosystems;

and water use in real time to help find which species provide the largest canopies for the lowest amount of water.

 With precise measurements of pollutant uptake, water use, plant growth rates, and greenhouse gas emissions,

Given enough time, Kampachi Farms will replace stagnant ponds with GPS-tracked cages stitched out of copper wire to enable a constant inflow of fresh ocean water without flushing out the precious fish.

This will be accomplished by nimble harvesting vessels driven by pioneers of this new life on the water.

The cool water pumped to the surface contains the exact ratio of nutrients oe including phosphorus oe needed to support plant growth.

With help from the Dutch aquatic architecture firm Deltasync, the institute hopes to design something that will meet the needs of residents,

To reach much deeper waters, communities will ditch the stilts and float freely or anchor.

Simple cement structures, reinforced with steel, can displace massive amounts of water, and last for decades-or even centuries.

Relieving the pressure on our stressed water resourcesno resource is more vital to the survival of the human species than water.

Beyond its obvious life-sustaining properties, water is a critical component for all aspects of human society.

when there will not be enough water for most people. If we continue along our current path,

the majority of humans will face chronic water shortages within two generations, widening the gap between the haves and the have-nots.

City managers worldwide will be forced to decide how water should be deployed; and there will not be enough to go round.

Consider the ancient aqueduct system built in the 4th century that supplied Constantinople with water from 250km away;

or the great water systems of the early industrial era, such as the watersheds, tunnels, aqueducts and reservoirs that fed oe and continue to feed-New york city.

500 sq km into both fertile agricultural land and a coastal buffer that reduced flooding and provided fresh water.

Ultimately, other crops could be planted on an area that was covered once with salt water. Precious resourcerethinking the spatial distribution of resources is one strategy that can have tremendous impact on reducing demand

improving available volumes of grey water and enhancing efficiency of infrastructure. To this end, at the regional level, we would have to examine the symbiotic relationship between patterns of urbanisation and industry.

We can make drinking water from water that's already been used by industry. For example, a new groundwater replenishment system in California's Orange county creates near distilled water from secondary wastewater after filtering

and disinfecting it with ultraviolet light. It has the potential to support 500,000 people. Additionally, it recharges a vast groundwater basin that supplies water to 20 cities and water agencies

serving more than 2. 3 million Orange Country residents. Â Conversely, treated water can also be used for industry.

Such is the case in agriculture, particularly in arid climates. For example, Jordan's Water Authority is presently treating domestic wastewater for reuse in agriculture;

water is an incredibly precious resource in this part of the world. Another widely used process for treating water that can expand our water resource is desalinisation.

However, desalinisation is energy-intensive and creates a hyper-saline brine that, when discharged, can harm aquatic ecosystems.

Advances in this technology have moved from an energy-hungry distillation process to a reverse osmosis process (essentially,

pushing saltwater through a membrane) and now to the utilization of carbon nanotechnology, which also reduces energy use (though not waste).

In Shanghai, in a project known as Houtan Park, artificial wetlands have been used to treat polluted waters along the city's Huangpu riverfront.

Water management strategies should also be implemented down to the level of industrial sites, where improvements can build on existing networks of freshwater tributaries, tidal estuaries,

mineral extraction and mining or fuel production oe rely on vast quantities of water. Cooling towers re-circulate water with the sole purpose of getting rid of heat,

and in the process, release large amounts of water to the atmosphere via evaporation and through contaminated water.

That's a lot of liquid coming out of what are stressed typically over water budgets. In some recent projects, designers instead employ recycled grey water.

For example, at the UK's Peterborough Power station, waste water from a nearby sewage treatment plant is used instead of drinking water.

In Phoenix Arizona, the Palo verde Nuclear power Plant is the world's only atomic power station not located adjacent to water.

Instead, it uses treated sewage water to cool steam. In The netherlands, a chemical plant in Terneuzen accepts more than 2. 6 million gallons of household wastewater each day.

Through a project developed for a new city in Saudi arabia, the design team Koetter Kim suggested cooling towers could be replaced by recirculating water through green space such as wetlands, walls of vegetation, agriculture and fountains.

The aquatic landscapes rely on the same evaporative and convective heat transfer processes used in the towers,

but allow the water to be recirculated. Moving this process from a tower into a chain of cooling landscapes adds green spaces to the environment

which can be used in a number of ways. Urban areas increasingly have to think of greener infrastructure that harnesses natural processes.

If these spaces fail to perform oe because of a lack of understanding about their functioning oe the results can be costly and environmentally damaging.

Therefore, we have to be able to measure the water-saving performance of these projects.

Increased interest in urban hydrology and stormwater management shows how badly our engineered landscapes fit into the land where they were built.

and how they can be adapted to conserve water. Routine modification of land through collaborative involvement in so-called"working landscapes  can aid learning

The task of conserving water can also be addressed on a smaller scale, beginning with improvements to architecture and homes.

The built center for the Women for Women International's Women's Opportunity Centre in Koyonza, Rwanda, includes a rain water capture

and supply system that supplies water to the site throughout the year. Composting toilets add nutrients for local farmland for lacking nitrogen

Grey water goes straight back to kitchen gardens. In 1949, the environmental scientist Aldo Leopold  wrote:"

  The same can be said for water. We need to work toward developing an appreciation of water, not merely as a commodity,

but as a lifeline of human civilisation. If you would like to comment on this article

if they'd just found a two-year-old child who had pulled a saucepan of boiling water over onto themselves.

A Turkish study found that only just over a quarter of the families had put cold water on a child's burn (the recommended approach),

the key is to get cold water onto the burn and to run it under the cold tap for longer than you think oe for at least 20 minutes.

Initially the cold water helps to numb the area by cooling it, but it also prevents the skin from continuing to burn.

but water is safer because the extreme cold can injure the tissue further. Finally the burn should be covered with a clean cloth

and waters warm there will be a global shift"from a fish to a jellyfish ocean Â. Its author Ferdinando Boero, Professor of Zoology at Salento University,

The loose skin on its large frame whips around its body with enough force to shed the water quite easily.

All of which is interesting, and indeed beautiful when seen in slo-mo. But shaking dogs may also have a practical application.

Strachan's idea was that changes to sewage treatment, availability of clean water and food,

cranberries were no more effective than drinking extra water, a placebo or even doing nothing. The review authors concede that some small studies showed an effect,

scientists are experimenting with dissolving the gas in water first and then injecting it into the rocks under high pressures.

Carbon dioxide can react with water to produce carbon monoxide and hydrogen oe a combination known as syngas because it can be turned readily into hydrocarbon fuels such as methanol or diesel.

Researchers assumed that it had drifted simply into deeper waters. Â It's far from being documented the only instance of dolphin death rituals.

The more samples they have in the database the more scientists can hope to use the technique to barcode everything from a whole environment to a cup of seawater.

who must pay to clean up their damage to soil, water or air, and to safely dispose of toxic waste.

and also help pay for remedial efforts from carbon capture and storage to waste water cleanup to recycling.

water taken up by plants is eaten by animals that breathe out water vapour, returning the water to the soil for the plants by way of rain.

Nothing is lost. But the scale with which we humans are using resources is too rapid for natural systems to manage.

Why damming world's rivers is a tricky balancing actwe remain desperately dependent on water for our survival.

With seven billion of us now needing water, agriculture, industry and to generate power, the human demand on global water supplies has never been greater.

And much of this is at the expense of the other water users on this planet oe all species need water

and ecosystems around the world are suffering from the decline in supply. Our problem is that 97%of our planet's water is salty ocean.

Of the 2. 5%that is fresh, most of it is trapped in glaciers in Antarctica, Greenland and mountains.

Just 0. 008 of 1%of all the water On earth is held on the surface in rivers,

Since ancient times people have found many ways to store water oe from trapping roof run off to underground monsoon storage.

Dams are a great way to store water for release during drought, to modulate damaging floods,

and to provide electricity by passing falling water through turbines. Environmental losstwo-thirds of the world's major rivers have now been disrupted with more than 50,000 dams in an attempt to store water

and provide power. In the US, there are more than 85,000 dams, stoppering large and small rivers,

however, inappropriate flooding of vegetation can cause greenhouse gas emissions and poison the water for fish.

Also, the dramatic rise and fall of water levels during dam releases oe sometimes of several metres oe is too extreme for plants

In many cases the upstream-downstream demands straddle national borders leading to conflict over precious water,

Dams don't just block water flow. They also prevent fish migrations up-and downstream, and dams are a barrier to sediment flows.

and now heads the Water division at the International Institute for Environment and Development, suggests the answer might be to issue dam builders with limited-length licences.

land and water use beyond anything our species has experienced before. We're polluting the biosphere,

and all will need food, water and clean air. As if to illustrate the point further, last month Arctic monitors showed the concentration of carbon dioxide in the atmosphere has passed 400 parts per million (before the Industrial Age,

Technology and innovation has saved already us from plagues, low crop yields, water shortages, reliance on fossil fuels and more.

If we destroy the water supply, the air, the climate, humanity will not be safe, Â he says,

But the principle is same oe these water-pipes allow you to smoke flavoured tobacco as it is bubbled through water.

because it is purified as it passes through the water. But this ignores the complete source of the smoke that enters your mouth.

You inhale through a mouthpiece connected by a pipe to a reservoir of water at the bottom.

As you breathe in smoke is drawn from the burning tobacco and bubbles through the water and up into your mouth.

Unknown riskbut surely the water cools the smoke, making it less dangerous than a cigarette?

with the support of IBM's World Community Grid, set up Computing for Clean Water to use computing power from more than 50,000 volunteers to virtually design better low-cost, low-pressure water filters,

And when you factor in climate change, limited fresh water supplies and competition for harvests from biofuel makers, it is clear the world faces a major challenge.

they found a strain that did not waste precious energy trying to elongate itself above the waters when submerged by a flash flood,

so that they can identify how much seed, fertilizer, water, herbicides and pesticides different areas require. At first the appeal was that farmers would save money

and avoid environmental harm by not adding unnecessary fertiliser or water, Khosla says.""But with precise input management, farmers can also influence grain yield and efficiency.

A third is the lack of water. Â Khosla says.""We're working under tremendous pressures today compared to those in the first green revolution.

but in both cases the effects of human excretion (through breathing or due to waste water treatment) are next on the list.

Human Excretion Contributes Nutrients oehuman excretion contributes significantly to water polluting through providing organic matter and nutrients

which fosters the growth of algae, a decrease in the level of oxygen dissolved in the water,

The researcher makes the point that returning these wastewaters to the environment is not a bad thing in itself,

and find it difficult to soak up wastewaters, not only from excrements, but also from other sources such as pesticides and fertilisers used in farming and pollutants from industry,

and the energy consumption associated to aspects such as using toilet paper, soap and basin water, together with the treatment of sewage at treatment stations.
