biotechnology

A collection of processes that involves the use of biological systems for altering and, ideally, improving the characteristics of plants, animals, and other forms of life.

famine

An extreme shortage of food, which leads to massive starvation in a population; often associated with crop failures, war, and political unrest.
(extreme form of chronic hunger)

food desert

An impoverished area with little access to healthy foods - where 33% or 500 people, whichever is less, live more than a mile from a grocery store in an urban area or more than 10 miles away in a rural area.

genetic engineering

Manipulation of the genetic makeup of any organism with recombinant DNA technology.

genetically modified organism (GMO)

Any organism created by genetic engineering.

green revolution

This refers to increases in crop yields that accompanied the introduction of new agricultural technologies in less-developed countries, beginning in the 1960s. The key technologies were highyielding, disease-resistant strains of rice, wheat, and corn; greater use of fertilizer and water; and improved cultivation practices.

human immunodeficiency virus (HIV)

The virus that leads to acquired immune deficiency syndrome (AIDS).

hunger

The primarily physiological (internal) drive to find and eat food.

infrastructure

The basic framework of a system of organization. For a society, this includes roads, bridges, telephones, and other basic technologies.

malnutrition

Failing health that results from longstanding dietary practices that do not coincide with nutritional needs.

recombinant DNA technology

A test tube technology that rearranges DNA sequences in an organism by cutting the DNA, adding or deleting a DNA sequence, and rejoining DNA molecules with a series of enzymes.

sustainable agriculture

Farming systems that can indefinitely maintain their productivity
Agricultural system that provides a secure living for farm families; maintains the natural environment and resources; supports the rural community; and offers respect and fair treatment to all involved, from farm workers to consumers to the animals raised for food.

sustainable development

Economic growth that will simultaneously reduce poverty, protect the environment, and preserve natural capital.

transgenic

Organism that contains genes originally present in another organism.

undernutrition

Failing health that results from a longstanding dietary intake that is not enough to meet nutritional needs.
