Zorluk: ZorAgricultural Systems and Practices in Africa

Match each African agricultural system or development scheme with its corresponding environmental adaptation or operational characteristic.

  • Chitemene system of ZambiaSlash-and-burn technique utilizing branch ash to neutralize acidic woodland soils for cereal crops.
  • Office du Niger scheme in MaliGravity-fed irrigation system along the Inland Niger Delta focused on rice and sugarcane cultivation.
  • Terraced agriculture of the Mandara MountainsStone-walled contour farming designed to prevent soil erosion and conserve moisture on steep slopes.
  • Market gardening of the WitwatersrandIntensive peri-urban horticulture providing fresh produce and dairy to major industrial and mining centers.

Cevap

The Chitemene system matches with the slash-and-burn ash fertilization technique; Office du Niger matches with gravity-fed Niger Delta rice and sugarcane irrigation; Terraced agriculture in the Mandara Mountains matches with stone-walled contour farming for soil conservation; and Witwatersrand market gardening matches with intensive peri-urban farming supplying industrial centers.
Each agricultural system is accurately paired with its primary geographical adaptation: Chitemene utilizes woodland ash beds in Zambia; Office du Niger harnesses Niger River irrigation in Mali; Mandara Mountain agriculture uses stone terrace contours for slope management; and Witwatersrand market gardening supplies high-demand peri-urban industrial centers in South Africa.

Adım Adım Çözüm

1
Analyze the traditional indigenous land-use system in Central Africa (Zambia).
Identify that Chitemene relies on pollarding trees and burning brush to create fertile ash spots in nutrient-poor miombo soils.
Ash fertilization is essential to reduce acidity and boost potassium and phosphorus levels for crop growth.
2
Evaluate the state-sponsored river basin irrigation development in West Africa (Mali).
Identify that the Office du Niger uses Niger River waters redirected via canals for paddy rice and sugarcane in the Sahelian zone.
Large-scale gravity canal networks bypass regional rainfall limitations to enable wetland farming.
3
Examine highland soil conservation strategies in West/Central Africa.
Identify that Mandara Mountain indigenous farming utilizes stone terraces built along steep contours.
Terracing reduces slope gradient, prevents topsoil erosion, and captures scarce runoff.
4
Determine commercial agricultural responses to dense urban and mining markets in Southern Africa.
Identify that Witwatersrand market gardening specializes in intensive, high-value perishable produce.
Proximity to large urban and industrial centers minimizes transport time and spoilage for dairy and fresh vegetables.
