Water can be the most critical problems in the future and it was expected will not able to meet demand of the globalized market later on. This situation has potential to become worst due to water scarcity in many parts of the world could harm the global economy in many ways that we had not thought of. For example, shortfalls in crop yields, fresh water supply to power plants, factories and the production with high protein food such as dairy, meat and fish.
Our demand for water is closely linked to economic growth. As we grow wealthier, the more freshwater we require supplying cities. In future, it is not just a question of more people requiring more water. However, there will be more wealthy societies demanding much more water. …show more content…
Water crises have become the top 10 risks in terms of impact over the next 10 years. Currently about 70% of the world's freshwater withdrawals are for agriculture, 16% are for energy and industry and 14% are for domestic purposes.
Decision-makers from the countries will be forced to make a tough judgment about allocations of water that will impact users across the economy. The situation will worsen further if more tragedies made by human towards our environmental. For example, the current tragedy in Fukushima power plant disaster was threatening to contaminate both freshwater and seawater.
How serious is our water challenge?
Lack of clean water is responsible for more deaths in the world than war. About 1 out of every 6 people living today do not have adequate access to water, and more than double that number lack basic sanitation, for which water is needed. In some countries, half the population does not have access to safe drinking water, and hence is afflicted with poor health. By some estimates, each day nearly 5,000 children worldwide die from diarrhea-related diseases, a toll that would drop dramatically if sufficient water for sanitation was …show more content…
The International Energy Agency forecasts that, the world economy will demand at least 40% more energy by 2030. Increasing access to energy is a priority for many countries. 1.5 billion peoples in the developing world still lack of access to electricity. Yet, energy needs a lot of water. In richer countries, up to 50% of freshwater withdrawals can be used in the production of oil, gas and electricity.
If we look at US as an example, they estimates that to produce and burn the 1 billion tons of coal the country uses each year require withdrawing 55tn to 75tn gallons of water annually. In other words, about half of all water withdrawals in the US today are used to cool electricity generating stations. This water also is not for consumption, but it is withdrawn from rivers and reservoirs and used for cooling then returned. But, access to the freshwater is still vital.
Against a baseline of 70% of water already being used for agriculture, how can these competing challenges be squared
