If a high rainfall area has unstable slopes and rapid erosion, what should be the priority for vegetation conservation?

Answer and explanation

Correct answer: Slope stabilisation and soil conservation

In a high-rainfall area with unstable slopes and rapid erosion, the first priority should be slope stabilisation and soil conservation, so option A is correct. Plant roots help hold soil together, while vegetation cover reduces the direct force of falling rain and slows surface runoff. Measures such as planting suitable vegetation, terracing and controlling runoff can reduce erosion.

Increasing deforestation or allowing uncontrolled grazing would remove plant cover and make slopes more fragile. Blocking drainage is also unsafe because excess water can increase saturation and trigger slope failure. Therefore, conservation must address both the unstable relief and the loss of soil. The correct approach is protection, not activities that disturb the slope.
