Quick Answer. Neo-Malthusian theory holds that population growth is exponential and that human population growth can easily outstrip its food resources if not held in check with artificial birth control measures. It differs from traditional Malthusian theory in the proposed birth control solution.
Terrace farming is when farming is done on manmade terraces that have been built into slopes. When humans transform a slope into a series of flat surfaces, they form terraces. Crops are then grown on these flat surfaces rather than on the slope, preventing crops from sliding down the slope over time. The image below is of rice paddies grown on terraces. By building these terraces, water flows down and accumulates in each terrace. If the terraces did not exist, rainfall and water would flow from higher elevations down the hill/mountain, carrying important soil and nutrients with it. Building terraces prevents this from happening.
The following are examples of types of farmers, ranchers, and other agricultural managers: Crop farmers and managers âthose who grow grain, fruits and vegetables, and other cropsâare responsible for all steps of plant growth.After a harvest, they make sure that the crops are properly packaged and stored.Livestock, dairy, and poultry farmers, ranchers, and managers feed and care for animals.merican farmers, ranchers, and other agricultural managers produce enough crops and livestock to meet the needs of the United States and for export. However, farm output and income are strongly influenced by weather, disease, fluctuations in prices, and federal farm programs.
