Human Food and Water Shortages
For humans, climate change may not only diminish seafood from the oceans; it also may mean declining water supplies and decreased agricultural productivity. Although some regions may experience floods and rising seas, other parts of the world will
In drought-ravaged Moyale, Ethiopia, cattle are led to one of the few remaining watering holes in the region. This lack of water, along with other climate changes, can cause a decline in food production, affecting the lives of millions of people.
suffer from drought and reduced rainfall. With the world's population rapidly increasing, these problems could become very serious, producing widespread water shortages and more hunger and malnutrition, especially for people in less developed areas. According to the IPCC, hundreds of millions of people in Africa and Latin America will not have enough water to live in less than twenty years, and by 2050, hundreds of millions in Asia could face the same situation. By 2080, water shortages could threaten a total of 1.1 billion to 3.2 billion people.
This lack of water, along with other climate changes, in turn, could cause a decline in food production, particularly in developing countries located close to the equator such as India and Sudan. According to William Cline, a senior fellow at the nonprofit Center for Global Development, developing countries are predicted to suffer an average 10 to 25 percent decline in agricultural productivity by the 2080s. As a result, the IPCC projects that by 2030, malnutrition will rise dramatically, and that by 2080, 200 million to 600 million people could go hungry.
