Which benefit did the 'waru waru' ridged field system provide to agriculture in the Andean highlands?

💡 Explanation

With waru waru, the water within the channels between ridges acts as a thermal buffer via latent heat of fusion, releasing heat during freezing because water's large specific heat capacity reduces nightly temperatures decreases on the plants. Therefore frost damage is minimized, rather than increased water availability, reduced evaporation, or enhance pesticide effectiveness which operate through fundamentally different mechanisms .
