A farmer in a hilly region of Maharashtra builds continuous contour trenches (CCT) along the slopes. What is the primary objective of this practice?
  1. To slow down running rainwater and allow it to seep into the soil.
  2. To drain rainwater quickly into the river down below.
  3. To collect topsoil and wash it down to the valley.
  4. To store surface water permanently on top of the hills.

Solution

Continuous contour trenches reduce the speed of surface runoff on slopes, checking soil erosion and helping rainwater percolate into the ground to recharge groundwater levels.
