Ecological amnesia: Why societies repeatedly forget environmental lessons

  • Gayatri Mishra

摘要

Societies around the world continue to face familiar ecological crises, including, deforestation, fisheries collapse, droughts. Yet the lessons these events offer are rarely carried forward across generations. This perspective introduces ecological amnesia to explain why environmental learning fades and why many conservation gains remain short-lived. Ecological amnesia emerges when ecological, institutional, and cultural memory systems weaken, leaving societies less able to read early warning signs, recognise slow-moving risks, or maintain protective measures once immediate pressures subside. The problem is reinforced by temporal mismatches: ecological recovery unfolds slowly, while political cycles, economic incentives, and public attention move far more quickly. Drawing on examples from forests, water systems, coral reefs, and fisheries, the perspective examines how misleading signals of recovery and shifting ecological baselines obscure functional fragility and reduce momentum for sustained action. It also highlights how ecological memory can be strengthened through long-term monitoring, continuity of environmental data, indigenous and local knowledge, and governance arrangements retaining lessons beyond short-term cycles. Recognising ecological amnesia as a source of vulnerability provides a explanation for the repeated nature of environmental crises and points towards forms of governance better suited to sustaining resilience as climate pressures intensify.
