Traditional forest-related knowledge and agrobiodiversity preservation: the case of the chagras in the Indigenous Reserve of Monochoa (Colombia)

Abstract

Chagras are complex agroforestry systems developed by indigenous populations of the Amazon region based on shifting agriculture, as part of a system that includes harvesting of wild fruits and plants, hunting and fishing. During the centuries, thanks to their traditional knowledge, indigenous populations have developed a deep relationship with the surrounding environment, as, living in remote places, they must be self-sufficient. The result is the chagra, a system whose cycle is based on seven basic steps to establish a successful and sustainable system, starting from place selection and ending with the abandonment of the plot after harvesting of the products. After the abandonment, the forest starts to grow again to allow the agroecosystem to recover and to take advantage of the residual vegetal material to avoid erosion. The paper takes into consideration the Indigenous Reserve of Monochoa in Colombia as an example of how traditional knowledge can support a rich biodiversity conservation. Moreover, differently from other parts of the world where there is a growing contrast between indigenous communities and protected areas, in the Indigenous Reserve of Monochoa local communities have been recognized as the owners of the land. Results highlighted the crucial role of the indigenous communities for biodiversity conservation. The preservation and adaptation of traditional knowledge and practices, a decentralized autonomous governance system demonstrates that local communities not only can be part of ecosystems with unique biodiversity, but that they can represent the main actors for an active conservation of biodiversity. Agroforestry systems based on traditional forest-related knowledge can therefore be an effective alternative to biodiversity and ecosystem services conservation based on strict nature protection where humans are perceived as a negative factor.
