The major causes of famine are poverty, trade barriers, corruption, mismanagement, ethnic antagonism, anarchy, war, and male-dominated societies that deprive women of food. Local land depletion, itself a consequence of poverty and institutional failure, is also a factor. Those who are too poor to use sound farming practices are compelled to overexploit the resources on which they depend.
The problem of famine is manifold:
The African continent in the mid 1980's suffered from famines on a scale never before witnessed. As of April 1985, 10 million people had abandoned their normal homes in search of food and water; 20 countries had been critically affected by drought; and 35 million lives were in danger.
Since the 1990's, notable famines have been man-made and in war zones like Somalia, Sudan, North Korea, Ethiopia, Democratic Republic of Congo, Kosovo, Nicaragua, Tajikistan, and Sierra Leone.
