Which advantage did the 'waru waru' cultivation technique provide to Andean communities versus simple terrace farming?

💡 Explanation

When temperatures dropped, thermal mass of raised beds in Waru Waru cultivation regulated soil temperature upwards because daily absorbed solar radiation kept the subsoil warmer, mitigating frost damage to crops. Therefore temperature regulation resulted, rather than erosion control, nitrogen fixation or improved pest control, which rely on different ecological mechanisms.
