Final Answer:
The Yanomamo people primarily rely on subsistence farming for their livelihoods, cultivating approximately 70% of their food in gardens.
Step-by-step explanation:
The Yanomamo an indigenous tribe in the Amazon rainforest, practice subsistence farming as a vital component of their traditional lifestyle. Their agricultural activities center around cultivating crops in gardens to meet their dietary needs. The 70% figure represents the proportion of their total food supply derived from these cultivated plots. This statistic is a result of meticulous anthropological studies and field observations.
In the dense rainforest environment where the Yanomamo reside, the availability of arable land is limited necessitating efficient use of the land they do have. The Yanomamo employ slash-and-burn techniques clearing small areas of the forest for cultivation. This cyclical process allows them to rotate their gardens to maintain soil fertility. The calculation of 70% involves considering the diversity of crops grown including plantains, bananas, cassava, and other staples. The reliance on subsistence farming underscores the Yanomamo's deep connection to their environment and their ability to sustain themselves within the constraints of their ecosystem.
The significance of this 70% figure lies in understanding the self-sufficiency of the Yanomamo in sourcing a substantial portion of their nutritional requirements from their own efforts. It reflects the resilience of their agricultural practices in an environment where resources are finite, emphasizing the adaptability and sustainability inherent in their subsistence lifestyle.
