5 things about water and climate changing that need to know
According to the report of The World Economic Forum in 2016 on "Global Risks Report," in the coming decades the water crisis will increase. Here is 5 reasons:
Climate change is the change of water
In essence, climate change is changing the water! Urban heat generated and the heat generated heat waves, melting ice and floods devastated a prolonged drought, forest fires, shrinking reservoirs, sea level rise, land arid and lowering underground water - all of which are the result of the increase in carbon pollution and is derived from a shortage of water distribution changes on earth. Whenever we speak about climate change, it is the transformation of the country including excess or shortage of water resources. So dealing with climate change is to prepare the plans for urban and rural areas and industries dealing with floods, droughts.
Warmer temperature and drought cause more pressure on food security and political stability
A study by McKinsey and Company comprehensively predict that in the next 15 years, demand for water will increase in the world at 40% vo sustainable use can meet. This amount includes the amount of water needed for the development process of the population, which, according to estimates, will need more food up to 50% in 2050. Agriculture employs over 90% of water consumption globalization and climate change impact on agriculture with paralyzing effects: higher temperatures reduce crop yields, depletion of rain or the water will affect crops. In countries with political instability, a breakdown in food production could spark economic decline and political crisis and social. For example, a 2015 study in the Proceedings of the National Academy of Science concluded that crop failure due to climate change is one of the reasons that triggered the civil war in Syria.
Using the water resources reasonably to help produce energy efficiency and reduce energy use as well as saving water
The efforts on the efficient use of water resources: water transfer, water treatment, cleaning, heating .. .From it also deplete water resources. The link between energy and water is manifested on all continents. In India, power outages in the summer of 2012 are related to the excessive use of electrical energy used to pump underground water for the drought of the Indian farmers. In areas under pressure on water resources, such as Singapore, Libya and Yemen, the water infrastructure requires using large amounts of energy. The link between water and energy together companion, companion energy development with energy resources development use of water resources. Eg coal, an important source of fuel in the world, also requires a huge amount of water in the process of mining and processing. Water is used for cooling the energy production from coal, gas, or biogas atomic nucleus. Sweden, of course, is related to the country and also one of the causes of drought. Therefore, the process of energy country- is an important component, proper use of water helps produce energy efficiency and reduce energy use as well as save water.
Climate change is exacerbating the pollution of water sources and disease outbreak
According to calculations, for every 10 people in the world, with 1 person not yet have access to the water supply system of high quality (equivalent to about 663 million people). Any change in climate can cause impacts on water supply somewhere in the world. Example: Algae bloom phenomenon, plague in the Great Lakes region of the United States and Canada as well as in China and India, will become more frequent due to rising lake water temperatures, increased production of nutrients and chemicals in the water (causing algae blooms); Drought will increase the concentration of pollutants in rivers and groundwater. Floods inundate the treatment facility and cause toxic sewage overflow; Diseases like dengue thrive in warm moist conditions will spread faster and extends beyond the tropics. Therefore, adaptation strategies have taken into account a combination of strategic water, sanitation and health will revive and strengthen the economy.
It's time to take our concern about the water more than the climate
A 2015 poll by the Pew Research Center study showed that 45% of Americans think climate change is a "very serious problem", while an international survey (GlobeScan / Circle) Blue's organization in 2009 showed that 87% of respondents in the United states are concerned about the shortage of fresh water. This percentage is higher than the worldwide survey. Therefore, the ability to cope with the water problems of the developing countries, especially those with low infrastructure poor countries have an important role in the process of dealing with global warming climate . Accordingly, greater efforts should be focused clarify the linkages between water tight
