How does water affect climate?
Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range.
What is water scarcity?
Water scarcity is defined as a water deficiency or a lack of safe water supplies. As the population of the world grows and the environment becomes further affected by climate change, access to fresh drinking water dwindles. Globally, 785 million people lack access to clean drinking water.
How does water pollution affect global warming?
Right now, the world’s oceans absorb 25% to 50% of carbon dioxide in our atmosphere. But the ocean isn’t able to absorb carbon dioxide as fast as we are polluting, which has led to both global warming and ocean acidification.
How does water scarcity affect Africa?
Water scarcity can also lead to diseases such as trachoma (an eye infection that can lead to blindness), plague and typhus. Water scarcity affects 1 in 3 people in the African Region and is getting worse with population growth, urbanization and increases in household and industrial uses.
How does water scarcity and drought affect the economy?
Farmers may lose money if a drought destroys their crops. If a farmer’s water supply is too low, the farmer may have to spend more money on irrigation or to drill new wells. Ranchers may have to spend more money on feed and water for their animals.
How does water scarcity affect development?
Water scarcity leads to food shortages while raising commodity prices thereby hindering trade with developing economies and in the long run cause civil unrest. Water scarcity has a direct impact on rain-fed and irrigated agriculture as well as livestock, and an indirect impact on food processing industries.
Who is most affected by water scarcity?
Women and children are the most affected — children because they’re more vulnerable to diseases caused by dirty water and women and girls because they often bear the burden of carrying water for their families for an estimated 200 million hours each day.
