Traditional ecological knowledge on the slope of Mount Lawu, Indonesia: all about non-rice food security

As a country with rice as the staple food, the dominant traditional ecological knowledge (TEK) on food in Indonesia is rice. However, in Tawangmangu District, Central Java Province, the TEK inherited from their ancestors is about non-rice food security. This study aimed to explore how villagers pass on and practice their knowledge and beliefs in food defense based on traditional ecological knowledge. The data were collected through FGD, interviews, and field observations of traditional ceremonial processions, agricultural activities, and natural resource management. The results showed that TEK in Tawangmangu had three themes, including (1) TEK communication and inheritance through folktales on the origin of vegetables and corn, taboo words, such as the prohibition of planting rice, and the symbolic meaning of traditional rituals and offerings; (2) the people’s philosophy is reflected in their view of God, ancestors’ spirits as folktales figures, village guards’ spirits, and other living things. The folktales protagonists’ spirits are asked to provide protection, while the antagonists' spirits are asked not to interfere; and (3) natural resources sustainability involves maintaining non-rice plant commodities, terraced agricultural land management, intercropping systems, managing water resource and crop yields, and traditional houses architecture. The locals protect the forest on Mount Lawu and Pringgodani Cave as their source of life by prohibiting cutting trees and reforestation.
