Feeding a growing world
Abstract:Technology allows for the increased production of food to meet the demands of a rapidly growing population. However, in poor countries, technology may not be economically or environmentally affordable. The balance between food supply and population growth will depend upon government's ability to design and enforce policies and programs to deal with increased population, poverty, and environmental degradation. Approaches will be specific to a country's needs. In Bangladesh, food aid will be needed. In Zaire, political reform will be required. Many countries will have to shift from investments in war to social development. Three kinds of countries will experience difficulty in feeding their populations: 1) countries with little or no reserves of fertile land or water and insufficient funds for food imports; 2) countries that have sufficient reserves of land and water but suffer from government policy failures and neglect of agriculture; and countries with political instability and civil war, which invariably are linked with famine and drought. The future prospects will be a slow increase in dietary intake in most regions, fluctuations in food availability and prices, increased crop yields and land under cultivation, and slower expansion of agricultural lands due to environmental constraints. Pessimists have predicted increased environmental costs of food production due to soil erosion, pesticide contamination of soil and water, loss of species, and fertilizer run-off. Optimists have argued that new lands can be brought under cultivation and investments in agricultural research can help to increase food productivity. As Population Council vice president in the Research Division, John Bongaarts has reiterated that a positive outcome is more likely if population growth can be stopped.
