Since the '90s the world population has gone up by around 2 billion but the rate of hunger is declining showing an impressive improvement. Compared to 23.3% of the population in developing regions a quarter century ago, only 12.9% are hungry in today's scenario.
The world's hungry people consume fewer than the 2,000 or so daily calories the average person needs to survive. Pedro Sanchez, Director of Agriculture and Food Security Center at Columbia University said that there are two main reasons for it.
People who are chronically hungry do eat. But their diet tends to consist of food like cereal, corn, cassava and rice high in calories and carbohydrates.
Even then, these people eat so little that it barely fills their stomach with the calories they need. And they don't eat the vegetables, meat, fish and/or dairy products that provide ample protein, vitamin A, zinc, iron and iodine, says Sanchez.
Seventy-two out of 129 countries, which were, surveyed in 2005 reduced hunger rates to about half. It was achieved by filling their stomachs with "maize, flour, rice and the like," says Sanchez. To curb vitamin and mineral deficiency, foods like protein-rich legumes (peanuts, beans and soybeans), milk, fish and meat should be introduced.
It can be achieved by increasing the yield of crops in small farming communities by providing seeds selectively bred to produce crops that can survive the harsh weather in some of these countries as well as training small farmers to use manure and other fertilizers to improve the soil.
