Why People are Hungry in this world...

Number of hungry people in the world

925 million hungry people in 2010

Does the world produce enough food to feed everyone?

The world produces enough food to feed everyone. World agriculture produces 17 percent more calories per person today than it did 30 years ago, despite a 70 percent population increase. This is enough to provide everyone in the world with at least 2,720 kilocalories (kcal) per person per day according to the most recent estimate that we could find.(FAO 2002, p.9). The principal problem is that many people in the world do not have sufficient land to grow, or income to purchase, enough food.

What are the causes of hunger?

What are the causes of hunger is a fundamental question, with varied answers.

Poverty is the principal cause of hunger. The causes of poverty include poor people's lack of resources, an extremely unequal income distribution in the world and within specific countries, conflict, and hunger itself. As of 2008 (2005 statistics), the World Bank has estimated that there were an estimated 1,345 million poor people in developing countries who live on $1.25 a day or less.³ This compares to the later FAO estimate of 1.02 billion undernourished people. Extreme poverty remains an alarming problem in the world’s developing regions, despite some progress that reduced "dollar--now $1.25-- a day" poverty from (an estimated) 1900 million people in 1981, a reduction of 29 percent over the period. Progress in poverty reduction has been concentrated in Asia, and especially, East Asia, with the major improvement occurring in China. In Sub-Saharan Africa, the number of people in extreme poverty has increased. The statement that 'poverty is the principal cause of hunger' is, though correct, unsatisfying. Why then are (so many) people poor? The next section summarizes Hunger Notes answer.

Harmful economic systems are the principal cause of poverty and hunger. Hunger Notes believes that the principal underlying cause of poverty and hunger is the ordinary operation of the economic and political systems in the world. Essentially control over resources and income is based on military, political and economic power that typically ends up in the hands of a minority, who live well, while those at the bottom barely survive, if they do. We have described the operation of this system in more detail in our special section on Harmful economic systems.

Conflict as a cause of hunger and poverty. At the end of 2005, the global number of refugees was at its lowest level in almost a quarter of a century. Despite some large-scale repatriation movements, the last three years have witnessed a significant increase in refugee numbers, due primarily to the violence taking place in Iraq and Somalia. By the end of 2008, the total number of refugees under UNHCR’s mandate exceeded 10 million. The number of conflict-induced internally displaced persons (IDPs) reached some 26 million worldwide at the end of the year . Providing exact figures on the number of stateless people is extremely difficult But, important, (relatively) visible though it is, and anguishing for those involved conflict is less important as poverty (and its causes) as a cause of hunger. (Using the statistics above 1.02 billion people suffer from chronic hunger while 36 million people are displaced [UNHCR 2008])

Hunger is also a cause of poverty, and thus of hunger. By causing poor health, low levels of energy, and even mental impairment, hunger can lead to even greater poverty by reducing people's ability to work and learn, thus leading to even greater hunger.

Climate change Climate change is increasingly viewed as a current and future cause of hunger and poverty. Increasing drought, flooding, and changing climatic patterns requiring a shift in crops and farming practices that may not be easily accomplished are three key issues. See the Hunger Notes special report: Hunger, the environment, and climate change for further information, especially articles in the section: Climate change, global warming and the effect on poor people such as Global warming causes 300,000 deaths a year, study says and Could food shortages bring down civilization?

Progress in reducing the number of hungry people

The target set at the 1996 World Food Summit was to halve the number of undernourished people by 2015 from their number in 1990-92. (FAO uses three year averages in its calculation of undernourished people.) The (estimated) number of undernourished people in developing countries was 824 million in 1990-92. In 2010, the number had climbed to 925 million people. The WFS goal is a global goal adopted by the nations of the world; the present outcome indicates how marginal the efforts were in face of the real need.

So, overall, the world is not making progress toward the world food summit goal, although there has been progress in Asia, and in Latin America and the Caribbean.

Micronutrients

Quite a few trace elements or micronutrients--vitamins and minerals--are important for health. 1 out of 3 people in developing countries are affected by vitamin and mineral deficiencies, according to the World Health Organization. Three, perhaps the most important in terms of health consequences for poor people in developing countries, are:

Vitamin A Vitamin A deficiency can cause night blindness and reduces the body's resistance to disease. In children Vitamin A deficiency can also cause growth retardation. Between 100 and 140 million children are vitamin A deficient. An estimated 250,000 to 500 000 vitamin A-deficient children become blind every year, half of them dying within 12 months of losing their sight. (World Health Organization)

Iron Iron deficiency is a principal cause of anemia. Two billion people—over 30 percent of the world’s population—are anemic, mainly due to iron deficiency, and, in developing countries, frequently exacerbated by malaria and worm infections. For children, health consequences include premature birth, low birth weight, infections, and elevated risk of death. Later, physical and cognitive development are impaired, resulting in lowered school performance. For pregnant women, anemia contributes to 20 percent of all maternal deaths (World Health Organization).

Iodine Iodine deficiency disorders (IDD) jeopardize children´s mental health– often their very lives. Serious iodine deficiency during pregnancy may result in stillbirths, abortions and congenital abnormalities such as cretinism, a grave, irreversible form of mental retardation that affects people living in iodine-deficient areas of Africa and Asia. IDD also causes mental impairment that lowers intellectual prowess at home, at school, and at work. IDD affects over 740 million people, 13 percent of the world’s population. Fifty million people have some degree of mental impairment caused by IDD (World Health Organization).
