One-fifth of the world’s population could starve and millions of others become climate refugees, forced by heat and drought to abandon their lands and hunt for food elsewhere in the coming decades of climate change. Immediate action is needed say experts

The potential that global warming has to dry up water resources in the American West and the food supplies of 1 billion people in the poorest regions of Africa and Asia are the focus of two studies released today.

Many of the world's poorest regions could face severe crop losses in the next two decades because of climate change, according to a new study by researchers at Stanford University's Program on Food Security and the Environment (FSE). Dr. David Kagan author of Sunstroke asks "Why can't we prevent this"? in his latest book, Doomwatch Legacy.

A shipment of bushmeat was apprehended in London. The bushmeat consisted of giant cane rats which are hunted and consumed for food in parts of Africa. Supposedly, the species is easily farmed as an alternative to bushmeat. However, unregulated animal meat especially bushmeat can spread diseases.

A famine is a widespread shortage of food that may apply to any faunal species, which phenomenon is usually accompanied by regional malnutrition, starvation, epidemic, and increased mortality.Although most famines coincide with regional shortages of food, famine in some human populations has occurred amid plenty or on account of acts of economic or military policy that have deprived certain populations of sufficient food to ensure survival. Historically, famines have occurred because of drought, crop failure, pestilence, and man-made causes such as war or misguided economic policies. Bad harvests, overpopulation, and epidemic diseases like the Black Death helped cause hundreds of famines in Europe during the Middle Ages, including 95 in the British Isles and 75 in France.During the 20th century, an estimated 70 million people died from famines across the world, of whom an estimated 30 million died during the famine of 1958–61 in China. The other most notable famines of the century included the 1942–1945 disaster in Bengal, famines in China in 1928 and 1942, and a sequence of man-made famines in the Soviet Union, including the Holodomor, Stalin's famine inflicted on Ukraine in 1932–33. A few of the great famines of the late 20th century were: the Biafran famine in the 1960s, the disaster in Cambodia in the 1970s, the Ethiopian famine of 1983–85 and the North Korean famine of the 1990s.Famine can be induced by a human population beyond the regional carrying capacity to provide food resources. An alternate view of famine is a failure of the poor to command sufficient resources to acquire essential food (the "entitlement theory" of Amartya Sen), analyses of famine that focused on the political-economic processes driving the creation of famine, an understanding of the complex reasons for mortality in famines, an appreciation of the extent to which famine-vulnerable communities have well-developed strategies for coping with the threat of famine, and the role of warfare and terrorism in creating famine. Modern relief agencies categorize various gradations of famine according to a famine scale.Many areas that suffered famines in the past have protected themselves through technological and social development. The first area in Europe to eliminate famine was the Netherlands, which saw its last peacetime famines in the early 17th century as it became a major economic power and established a complex political organization. Noting that many famines occur under dictatorship, colonial rule, or during war, Amartya Sen has posited that no functioning democracy has suffered a famine in modern times.
