    Solution

    Contour bunding is an effective technique for conserving soil moisture in dryland areas. It involves constructing bunds or ridges along the contour lines of the land. The bunds act as barriers to slow down the movement of water and trap runoff, allowing it to infiltrate into the soil and recharge the groundwater.
