Grid reference
A location on a map, which is found using the Northing and Easting numbered lines
Area reference
An area reference allows people to find a general location in a grid square. Area references comprise four-figure numbers. The first two figures are always an easting and the second two figures are always a northing.

Threats
Climate change
Climate change refers to the changes in temperature and weather patterns. Human activities are the main driver for this due to burning fossil fuels (like coal, oil and gas) which produces heat-trapping gases
Salinity
Salinity is the accumulation of salt in land and water to a level that damages the natural and built environment
Land degradation
Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land.
-
Competing land uses
Occurs when several agents demand the same good or service produced from a limited area. It implies that when one agent acquires scarce resources from land, less resource is available for competing agents.

Rooftop Farming
Extensive
most commonly with residential homes. Smaller fast-growing plants that can thrive in low water environments are usually the plant of choice. Some of these plants include grasses, herbs, succulents and sedum.
Intensive
made to support a lot of weight. They can be filled with all types of plants, shrubs, trees and sometimes they put fountains. Due to the extra weight these plants put, these types of rooftop gardens are mainly found on commercial buildings.
Vertical Farming
Vertical farming is the practice of growing crops using soilless farming techniques such as hydroponics, aquaponics, and aeroponics in vertically stacked layers
Green Revolution
The green revolution was a change in farming during the 1950s until 1979. There was a great increase in food production of food grains (especially wheat and rice) that resulted in large part from the introduction into developing countries of new, high-yielding varieties. The new varieties require large amounts of chemical fertilizers and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects.
