Olifants River farming and irrigation scheme. Landscape photo. Namaqua West Coast doesn’t get much rain. It is however among one of South Africa’s thriving agricultural regions thanks to an incredible network of canals, hundreds of kilometres in length. The construction represents a historic and engineering feat known as the Olifants River Irrigation Scheme and is the country’s oldest. The scheme’s open concrete canals transport water throughout the region. They start at the Bulshoek and Clanwilliam dams. The scheme was formally established in 1911, but has a history that goes back to the middle of the 19th century. Initially comprising hand-dug trenches, the canals were later solidified with concrete - a job that Italian POWs were engaged in during World War 2. Amazingly, there is not a single pump along the entire course of the canals. Like the Roman aqueducts, water flows from its source to dams spread across the region, by gravitation only. Valley for about 80 km. Principal crops produced in the area are lucerne, winter cereals, grapes and fruit.
