- Image A: Brazil. The near horizontal light area shows the main road through the darker dense rainforest. Lines at right angles to these are logging roads cut into the forest. Logging has taken place either side of the roads, and the farmers have followed, planting their crops into these cleared areas as these are the most accessible. 2
- Image B: Saudi Arabia. Rotational irrigation from a central source produces a fertile circular area that is cultivated (dark patches). The light areas around the circles are the un-irrigated desert/arid areas 2
- Image C: Vietnam. The image shows rice paddies with raised banks between the fields to enable flooding of individual fields. Canals visible which are used for irrigation; each field is accessible from the river/canal. The small size of the paddies reflects the largely un-mechanized intensive farming methods. 2
