Definitions Flashcards
Subsistence Farming is….
Subsistence farming is the practice of self-sufficiency in which the farmers focus only on producing enough food for personal consumption.
Extensive Farming is….
Extensive farming is a low-input, low-output way of growing crops or raising animals on large areas of land.
- Practiced in a moderately
populated region
- Large and inexpensive
- Remotely located
- Small
Intensive Farming is….
Intensive farming is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area.
- Practiced in a densely
populated region
- Small and Expensive
- Near to market
- Large
Degradation is….
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
Soil layers are….
The term “soil layers” refers to a soil horizon that runs parallel to the soil surface. Each layer of soil has unique biological and chemical characteristics from the preceding or subsequent layer. Soil layers gain strength and stability with time.
Salinity/salinization is….
Salinization is the increase of salt concentration in soil and is, in most cases, caused by dissolved salts in the water supply. This supply of water can be caused by flooding of the land by seawater, seepage of seawater or brackish groundwater through the soil from below.
Climate is….
Climate is the average course of weather conditions for a particular location over a period of many years.
Water Scarcity is….
Water scarcity is insufficient freshwater resources to meet the human and environmental demands of a given area. Water scarcity is inextricably linked to human rights, and sufficient access to safe drinking water is a priority for global development. Jordan is considered to be one of the ten most water scarce countries in the world due to the rise of temperatures and its high population growth.
Food security is….
Food security is defined by the Food and Agriculture Organization (FAO) as: when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life.
Accessibility is….
Food Accessibility means to have physical and economic access to food. Thus, there needs to be enough food available and it must be in reach to those who need it.
Availability is….
Food availability means people have enough food of appropriate quality available on a consistent basis.
Appropriate use is….
Appropriate use of food means using food safely and applying knowledge about nutrition, clean water and sanitation when preparing food.
Food insecurity is….
Food insecurity is being unable to consistently access or afford adequate food.
Geography is….
The study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources and political and economic activities.
Ecosystem services are….
Ecosystem services are the many and varied benefits to humans provided by the natural environment and healthy ecosystems. Such ecosystems include, for example, agroecosystems, forest ecosystem, grassland ecosystems, and aquatic ecosystems.
