Mexico Expedition Leader Melissa Silva explains the milpa crop system, a traditional Mesoamerican agricultural method that involves growing maize/corn, beans, squash and other companion crops to produce a host of benefits. Planted together, these crops enhance and maintain soil fertility and reduce erosion and could help mitigate global challenges like climate change, biodiversity loss and food insecurity.
