paragraph_text: Famine prevention
  
  Relief technologies, including immunization, improved public health infrastructure, general food rations and supplementary feeding for vulnerable children, has provided temporary mitigation to the mortality impact of famines, while leaving their economic consequences unchanged, and not solving the underlying issue of too large a regional population relative to food production capability. Humanitarian crises may also arise from genocide campaigns, civil wars, agro-terrorism, refugee flows and episodes of extreme violence and state collapse, creating famine conditions among the affected populations.
  
  Despite repeated stated intentions by the world's leaders to end hunger and famine, famine remains a chronic threat in much of Africa, Eastern Europe, the Southeast, South Asia, and the Middle East. In July 2005, the Famine Early Warning Systems Network (FEWS NET) labelled Niger with emergency status, as well as Chad, Ethiopia, South Sudan, Somalia and Zimbabwe. In January 2006, the United Nations Food and Agriculture Organization warned that 11 million people in Somalia, Kenya, Djibouti and Ethiopia were in danger of starvation due to the combination of severe drought and military conflicts. In 2006, the most serious humanitarian crisis in Africa was in Sudan 's region Darfur.
  
  Frances Moore Lappé, later co-founder of the Institute for Food and Development Policy (Food First) argued in Diet for a Small Planet (1971) that vegetarian diets can provide food for larger populations, with the same resources, compared to omnivorous diets.
  
  Noting that modern famines are sometimes aggravated by misguided economic policies, political design to impoverish or marginalize certain populations, or acts of war, political economists have investigated the political conditions under which famine is prevented. Economist Amartya Sen states that the liberal institutions that exist in India, including competitive elections and a free press, have played a major role in preventing famine in that country since independence. Alex de Waal has developed this theory to focus on the "political contract" between rulers and people that ensures famine prevention, noting the rarity of such political contracts in Africa, and the danger that international relief agencies will undermine such contracts through removing the locus of accountability for famines from national governments.
  
  The demographic impacts of famine are sharp. Mortality is concentrated among children and the elderly. A consistent demographic fact is that in all recorded famines, male mortality exceeds female, even in those populations (such as northern India and Pakistan) where there is a male longevity advantage during normal times. Reasons for this may include greater female resilience under the pressure of malnutrition, and possibly female's naturally higher percentage of body fat. Famine is also accompanied by lower fertility. Famines therefore leave the reproductive core of a population—adult women—lesser affected compared to other population categories, and post-famine periods are often characterized a "rebound" with increased births.
  
  Even though the theories of Thomas Malthus would predict that famines reduce the size of the population commensurate with available food resources, in fact even the most severe famines have rarely dented population growth for more than a few years. The mortality in China in 1958–61, Bengal in 1943, and Ethiopia in 1983–85 was all made up by a growing population over just a few years. Of greater long-term demographic impact is emigration: Ireland was chiefly depopulated after the 1840s famines by waves of emigration.
