Operationalising Rights of Nature: Ecological Reparations for the Cauca River, Colombia

In February 2024, Colombia's Special Jurisdiction for Peace (JEP) declared the Cauca River a victim of armed conflict - the first time a river has received such legal recognition. By December 2026, the JEP must determine what reparations are owed to address decades of ecological harm, including pollution, habitat destruction and biodiversity loss. This decision will establish global precedent for translating nature's legal rights into concrete environmental interventions.

Our interdisciplinary research integrates ecological science with transitional justice frameworks to inform this unprecedented reparations case. We developed quantitative assessments of ecological harm through species distribution modelling and analysis of environmental and conflict-related spatial data sets. These methods enabled us to establish baseline biodiversity conditions and attribute observed degradation to conflict-related activities versus other anthropogenic pressures.

Working alongside legal scholars, river stakeholders, and Colombian researchers, we are translating ecological findings into legally defensible reparative measures aligned with established principles of victim-centred justice. This requires navigating fundamental questions: How do we define "recovery" for a river system? Should reparations target the main stem exclusively, or must they address tributary networks? What temporal and spatial scales are appropriate for intervention?

Our emerging framework addresses these challenges through process-based restoration design that considers both immediate remediation needs and long-term ecosystem trajectory. The approach balances scientific rigour with the practical constraints of judicial timelines and implementation capacity in post-conflict contexts.

Beyond informing the Cauca case, this work establishes methodological precedent for operationalising Rights of Nature declarations globally. We demonstrate how ecological science can move beyond its advisory role to become integral in legal decision-making for rights-bearing natural entities. Our "blueprint" for nature reparations offers transferrable principles for future cases while acknowledging the site-specific complexity inherent in ecosystem restoration.

This presentation will share insights from bridging scientific assessment with legal implementation, examining both successes and challenges encountered when giving nature its own voice in justice processes. The work illustrates how interdisciplinary collaboration can transform symbolic legal recognition into measurable ecological outcomes.
