Vocabulary set for ch 12 of Living in the Environment 17th ed Miller
Where all or most of the people in the country have daily access to enough nutritious food to live active and healthy lives.
People living with chronic hunger and poor nutrition, which threatens their ability to lead healthy and productive lives.
This occurs when there is a severe shortage of food in an area and which can result in mass starvation, many deaths, economic chaos, and social disruption.
Occurs when food energy intake exceeds energy use and causes excess body fat.
Supplying water to crops by artificial means.
Industrialized or high-input Agriculture
A type of agriculture that uses heavy equipment and large amounts of financial capital, fossil fuels, water, commercial inorganic fertilizers, and pesticides to produce single crops, or monocultures.
A form of industrialized agriculture used primarily in tropical less-developed countries growing cash crops like bananas, soybeans, sugarcane, coffee, palm oil, and vegetables mostly for export to more-developed countries.
Involves growing plants by exposing their roots to a nutrient-rich water solution instead of soil, usually inside of a greenhouse.
Traditional Subsistence Agriculture
Agriculture that supplements energy from the sun with the labor of humans and draft animals to produce enough crops for a farm family's survival, with little left over to sell or store as a reserve for hard times.
Cultivating several crops on the same plot simultaneously.
A type of subsistence agriculture that involves burning and clearing small plots in tropical forests, growing a variety of crops until the soil is depleted, then shifting to other plots to begin the process again.
The increase in global food production since 1950 from using high-input industrialized agriculture to increase crop yields.
A concentration of particular aquatic species suitable for commercial harvesting in a given ocean area or inland body of water.
The practice of raising marine and freshwater fish in freshwater ponds or underwater cages in coastal or open ocean waters.
Occurs when the productive potential of topsoil falls by 10% or more because of a combination of prolonged drought and human activities such as overgrazing and deforestation that reduce or degrade topsoil.
A process that degrades soil from repeated applications of irrigation water in dry climates which leads to the gradual accumulation of salt in the upper layers of soil.
Where water accumulates underground and gradually raises the water table, especially when farmers apply large amounts of irrigation water in an effort to leach salts deeper into the soil, eventually killing plants.
Any species that interferes with human welfare by competing with us for food, invading lawns and gardens, destroying building materials, spreading disease, invading ecosystems, or simply being a nuisance.
Chemicals used to kill or control populations of organisms we consider undesirable.
Integrated Pest Management (IPM)
A program where each crop and its pests are evaluated as parts of an ecological system to form a control plan that uses a combination of cultivation, biological/chemical tools, and applied in a coordinated process tailored to each situation.
Involves using a variety of methods to reduce topsoil erosion and to restore soil fertility, mostly by keeping the land covered with vegetation.
Fertilizer from plant and animal materials.
Manufactured Inorganic Fertilizer
Fertilizer produced from various materials, which are mined from the earth's crust.
A type of organic fertilizer that uses dung and urine from cattle, horeses, poultry, and other farm animals.
Fertilizer that consists of freshly cut or growing vegetation that is plowed into the topsoil to increase the organic matter and humus available to the next crop.
Fertilizer produced when microorganisms in topsoil break down organic matter such as leaves, crop residues, food wastes, paper, and wood in the presence of oxygen.
condition suffered by people who cannot grow or buy enough food to meet their basic energy needs
Constant illness caused by lack of proper amounts of vitamins and nutrients Constant illness caused by lack of proper amounts of vitamins and other key nutrients, such as protein
The removal of soil by wind and water that exceeds the soil's natural replacement.
Traditional Intensive Agriculture
Farmers increase their inputs of human and draft-animal labor, animal manure for fertilizer, and water to obtain higher crop yields. Farmers can produce enough food to feed their families and supplement their income.
