In a context of environmental crisis, Chile begins to look to its past to find sustainable solutions. In Patagonia, indigenous communities promote ancestral practices that are now recognized by science as effective tools for marine restoration.
According to a study published in People and Nature, these techniques not only preserve cultural value but also strengthen biodiversity. Thus, they are positioned as concrete alternatives to the deterioration of coastal ecosystems.
Furthermore, the research, led by scientist Ricardo Álvarez, highlights the importance of integrating traditional knowledge and modern science. This opens a new path for marine conservation.
Traditional practices that regenerate the sea
The study analyzes experiences on Apiao Island and Ascension Island, where specific techniques are applied. On one hand, the pirene corrals consist of stone walls built in intertidal zones. These structures create shelters where species like fish of the genus Patagonotothen can reproduce.
On the other hand, underwater arrangements involve direct intervention of the seabed. In this regard, diving shellfishers rearrange the substrate to facilitate the recovery of species.
Together, both practices act as true ecological nurseries. Consequently, they allow for the restoration of favorable conditions for multiple forms of life.
The ecological logic behind ancestral knowledge
The functioning of these techniques is based on a key principle: the reciprocity between humans and nature. That is, each action is carried out considering its impact on the ecosystem.
Moreover, the corrals not only benefit the fish. They also create habitats for species like the Chilean oyster, the mussel, and various algae.
Additionally, these practices include sustainable use regulations. Therefore, reproductive cycles are respected and overexploitation is avoided.
In this way, the ecological balance is maintained over time. Consequently, both human subsistence and the health of the environment are ensured.
Current threats to marine ecosystems
Despite their effectiveness, these practices face multiple threats. Firstly, the expansion of the salmon industry generates significant impacts on the seabed.
Additionally, the accumulation of waste and the decrease in oxygen affect biodiversity. Consequently, many species see their living conditions altered.
On the other hand, intensive overfishing continues to degrade key habitats. Likewise, some fleets exceed permitted quotas, worsening the problem.
Finally, climate change introduces new pressures on marine ecosystems. Thus, rising temperatures and ocean acidification further complicate their recovery.
A bridge between tradition and a sustainable future
In this scenario, the integration between science and indigenous knowledge emerges as a promising strategy. In this sense, researchers highlight the need to strengthen these practices.
Moreover, supporting local communities is key to sustaining these systems. Therefore, their active participation becomes indispensable in conservation policies.
Ultimately, the experience of Patagonia demonstrates that effective solutions can arise from ancestral knowledge. Thus, the past is projected as an essential tool to face the environmental challenges of the present.
