+Channel the heat from power plants to give water to a thirsty world. That's the idea of a physicist from the Sont Longowal Institute in Punjab, India. Nuclear power plants have a lot of excess heat, so why not use that heat to make fresh water? That's the idea of S.S. Verma, with the Department of Physics at the Sont Longowal Institute in Punjab, India. If located offshore near large population centers, the plants could provide cheap electricity as well as fresh water to megacities like Mumbai.¶ Some companies are already looking at developing desalination platforms that can be attached to nuclear plants, he said, according to the Indo-Asian News Service (via Earthtimes). (Verma's complete paper can be found here.)¶ The general and very serious concerns about nuclear power~-~-what do you do about transportation of nuclear materials? Disposal and storage? Safety?~-~-of course apply. But it's also an interesting idea. Nuclear plants do produce a lot of waste heat. Many believe that hydrogen could become economical if the waste heat from these plants could be used to crack water molecules to produce the gas.¶ Some companies in Canada are contemplating installing nuclear power plants near the tar sands deposits in Alberta to produce hydrogen, a necessary ingredient for turning the goopy tar into usable liquid fuel.¶ The world is mired in a water crisis. In many large cities in India, people wait in line to get water from roving trucks. Droughts and crop failures are expected to increase as global temperatures rise. And it's not just in the emerging world. Australia is suffering through a prolonged shortage of water.¶ Desalination provides an avenue out of it, but conventional methods are expensive and somewhat time consuming |

+Water shortages are becoming a threat to the existence of entire nations. The world countries are consuming increasingly large amounts of natural resources. The first major problem that the people of the world may come to face soon is a global shortage of water. Drinking water is already more expensive than oil. Thirst may eventually cause a repartition of the world.¶ We are living through a period of global warming. The annual average temperature has been on the increase. According to an international group of experts, the mean air temperature will be higher than now by 1.5 to 4.0 degrees Centigrade in the next 100 years. But even a two-degree rise in temperature is sufficient to cause glaciers to start melting. For countries like Central Asian nations, this is tantamount to a disaster, since they will face a period of never-ending drought, claims the Head of the Climate and Energy programme of the World Wildlife Foundation, Alexei Kokorin.¶ "Ice floes and glaciers accumulate snow water for winter snowfalls, thus providing water gradually, Alexei Kokorin says. If you have a glacier at your disposal, the water level in your river will prove acceptable throughout the summer. If there is no glacier, you will have torrential floods in spring, when snow melts in the mountains, and will then have no water at all. Things will not be that bad if you have hydraulic engineering installations. But these normally cost a pretty penny. Hydraulic installations in Central Asian countries are so old, they are underperforming."¶ Attempts to build new dams may cause international conflicts. For example, Uzbekistan has openly threatened Tajikistan with a declaration of war if Dushanbe builds the Rogun hydroelectric power plant on the Vakhsh River and thus limits the downstream water supply. |

+For years experts have set out warnings of how the earth will be affected by the water crises, with millions dying and increasing conflicts over dwindling resources. They have proclaimed ~-~- in line with the report from the US Senate ~-~- that the water scarcity is a security issue, and that it will yield political stress with a risk of international water wars. This has been reflected in the oft-repeated observation that water will likely replace oil as a future cause of war between nations. Today the first glimpses of the coming water wars are emerging. Many countries in the Middle East, Africa, Central and South Asia ~-~- e.g. Afghanistan, Pakistan, China, Kenya, Egypt, and India ~-~- are already feeling the direct consequences of the water scarcity ~-~- with the competition for water leading to social unrest, conflict and migration. This month the escalating concerns about the possibility of water wars triggered calls by Zafar Adeel, chair of UN-Water, for the UN to promote "hydro-diplomacy" in the Middle East and North Africa in order to avoid or at least manage emerging tensions over access to water. The gloomy outlook of our global fresh water resources points in the direction that the current conflicts and instability in these countries are only glimpses of the water wars expected to unfold in the future. Thus we need to address the water crisis that can quickly escalate and become a great humanitarian crisis and also a global safety problem. A revolution The current effort is nowhere near what is needed to deal with the water-challenge ~-~- the world community has yet to find the solutions. Even though the 'water issue' is moving further up the agenda all over the globe: the US foreign assistance is investing massively in activities that promote water security, the European Commission is planning to present a "Blueprint for Safeguarding Europe's Water" in 2012 and the Chinese government plans to spend $600 billion over the next 10 years on measures to ensure adequate water supplies for the country. But it is not enough. The situation requires a response that goes far beyond regional and national initiatives ~-~- we need a global water plan. With the current state of affairs, correcting measures still can be taken to avoid the crisis to be worsening. But it demands that we act now. We need a new way of thinking about water. We need to stop depleting our water resources, and urge water conservation on a global scale. This calls for a global awareness that water is a very scarce and valuable natural resource and that we need to initiate fundamental technological and management changes, and combine this with international solidarity and cooperation. In 2009, The International Water Management Institute called for a blue revolution as the only way to move forward: "We will need nothing less than a 'Blue Revolution', if we are to achieve food security and avert a serious water crisis in the future" said Dr. Colin Chartres, Director General of the International Water Management Institute. This meaning that we need ensure "more crop per drop": while many developing countries use precious water to grow 1 ton of rice per hectare, other countries produce 5 tons per hectare under similar social and water conditions, but with better technology and management. Thus, if we behave intelligently, and collaborate between neighbors, between neighboring countries, between North and South, and in the global trading system, we shall not 'run out of water'. If we do not, and "business as usual" prevails, then water wars will accelerate. |
