Evans, Lloyd T. 1998. However, cereal production (accounting for more than 50% of the energy intake of the world's poor today) has more than kept pace: It has increased from 275 kg per person in the early 1950s to 370 kg per person in the early 1980s. It leads to increased temperatures, weather volatility, unpredictable rainfall, withered rivers, and thus negatively impacts agricultural irrigation systems. In Mitchell, Donald O., Merlinda D. Ingco, and Ronald C. Duncan. Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. There is no doubt that given appropriate levels of investment this region's agricultural potential is considerable. The region's estimated per capita daily calorie supply for the years 1997 to 1999 suggests scant improvement compared to the 1969 to 1971 period. This is the world's poorest region and it has experienced the fastest demographic growth, with populations often doubling in less than 25 years.African farmers have been unable to raise their food crop yields at similar rates. For farmers who take a loan, this will cause them to be indebted.It is hard to ignore the overlap between countries that are severely impacted by climate change and countries that have large population growth. Most people are familiar with the terms "national security" or "home security," but relatively few are familiar with the term "food se… Food Aid for Development and the World Food Programme According to the UN’s 2017 revision, the world population is expected to reach Climate change is one of the major threats to world agricultural production. 2001. Expert commentary and analysis on global agriculture and food. The most positive developments have occurred in East Asia. 1997. Extreme weather and natural disasters are costing farmers in low- and middle-income countries billions of dollar each year. However, because there is little new land that can be brought into cultivation, almost all of this increase in food production has come about through processes of agricultural intensification: the improvements in food supply that China's growing population have enjoyed have occurred mostly through increasing food crop However, in the Middle East, where water for agriculture is often in short supply, many countries have also turned to purchasing sizeable quantities of cereals on the international market–much of which is then used as livestock feed in order to produce meat. Worldwide, Africa is epitomized as one of the Low- and middle-income countries with large population growth in Asia and Africa have good reasons to worry about climate change. Adding to this bleak outlook, the region may continue to experience food crises and famines–often with warfare acting as an important contributory cause.In considering the world's more developed regions, the situation is clearly very different. "World Food Trends: A Neo-Malthusian Prospect?" India is set to surpass China as the world’s most populous nation by as early as 2024. The relationship between a population and its food supply is a matter of prime importance. The world's population, now 5300 million, is increasing by approximately 250 000 people every day. The record of South Asia, however, is best described as patchy; and for sub-Saharan Africa it is bad. To ensure adequate food to feed the future population, actions are needed. Note that the relationship is fairly tight–sufficiently so to make a reasonably firm prediction that when the world's population reaches 8 billion, which it is projected to do around the year 2025, the world cereal yield will be slightly above four metric tons per hectare.

Average levels of food consumption may well rise, but this demographic growth, and recent trends in food demand and production, do not augur well for a major decrease in the total number of under-nourished people.In major world regions the food situation is probably grimmest in sub-Saharan Africa, where FAO (2000) estimates that in the period from 1996 to 1998 about one-third of the total population was undernourished.
