Agricultural Productivity - The ratio of useful output (yield) to input, showing the efficiency of a
farm.
Arable Farming - Growing crops and plant-based foods.
Asylum Seekers - People fleeing their country of residence for international protection by another
government.
Biologically Transmitted Disease - A disease that is passed on by a pathogen (e.g. a bacterium or
virus), causing illness, e.g. malaria
Boserup’s Theory - No matter how large the population grows, we will discover new ways to
sustain food supplies.
Commercial Farming - Agriculture with the intention of providing yields that can be sold
commercially, making a profit.
Cover Crop - A crop with a large surface area, used to cover a bare field to reduce soil erosion and
maintain the structure of the topsoil.
Crop Yield - The amount of grains, vegetables or fruits produced from a unit area of land (units =
kilograms per hectare).
Demographic Transition Model - A model describing overall population change, mortality and
fertility rates over time.
Density - The number of people per unit area (often per km2
).
Desertification - Fertile land becomes dry and desert-like, reducing in productivity and vulnerable to
erosion.
Development Process - The process of a society advancing over time through technological
improvements, changes in knowledge and attitudes or improving the efficiency of industrial
processes.
Ecological Footprint - The amount of resources used in relation to the available resources on
Earth. A footprint larger than 1 means consumption is greater than the available resources on Earth,
making it unsustainable living.
Economic Migrants - The movement of an individual to improve their financial wealth and quality of
living.
Epidemiological Transition Model - A model describing how morbidity varies - as a society
develops over time, infectious diseases will decrease but non-communicable diseases will increase.

Extensive Farming - Low inputs in relation to the amount of land farmed, i.e. low amounts of
labour, capital investment or stock needed to produce a sufficient yield, but without too much
investment.
Food and Agricultural Organisation (FAO) - An IGO which aims to improve global health by
reducing hunger.
Food Insecurity - An individual does not consume healthy food or the necessary energy input in
calories each day.
The Green Revolution - During the 1950s and 60s, more technology and efficient farming practices
