Why is the study of hill terraced farming integrative in geography?

Correct answer: Because slope, soil conservation, labour, crops and water management are connected

Option D is correct because terraced farming represents an interaction between the natural environment and human adaptation. On steep slopes, constructing steps reduces the length and force of flowing water, helping limit soil erosion and retain moisture. The design also depends on local geology, soil depth, rainfall and the availability of water. Farmers must decide which crops suit the altitude and climate, organise labour for construction and maintenance, and manage irrigation between terraces. In many regions, terraces support food production while reducing pressure on fragile mountain land, although they require continuous upkeep. Options A, B and C focus on only a superficial detail and cannot explain why the practice exists or how it works. Geography integrates relief, soil, climate, livelihoods, technology and conservation in this study.
