Renewable · Organic · Nexus-basierter Ansatz für Wasseraufbereitung, Anpassung, Transformation, Beteiligung und Resilienz
-
RONWATER ist ein regenerativer, naturbasierter und nexus-orientierter One-Water-Ansatz im Sinne des Integrierten Wasserressourcenmanagements (IWRM) zur Wasseraufbereitung, Klimaanpassung, systemischen Transformation, partizipativer Beteiligung und Stärkung der Resilienz von Ökosystemen und Gesellschaften.
Water Treatment
- Emphasizes sustainable and nature-based purification:
- Wetlands, reed beds, algae ponds, aquifer recharge.
- Decentralized, low-cost systems for communities.
- Turning wastewater into a resource (nutrients, biogas, irrigation).
Adaptation
- Focuses on climate adaptation and risk reduction:
- Managing droughts, floods, salinization.
- Enhancing water security under changing rainfall patterns.
- Designing flexible, resilient systems that evolve with climate change.
Transformation
- Refers to systemic change in water governance and practice:
- Moving from siloed, reactive management to integrated, proactive approaches.
- Shifting financial and institutional systems to support sustainable solutions.
- Encouraging cultural and behavioral change toward valuing water.

Engagement
- Highlights participatory and inclusive governance:
- Involving communities, women, youth, and marginalized groups in decision-making.
- Building trust and ownership for long-term sustainability.
- Co-creating solutions with local knowledge and science.
Resilience
- Refers to long-term capacity to withstand shocks and stresses:
- Ecological resilience: ecosystems continue providing services under stress.
- Social resilience: communities adapt, recover, and thrive despite challenges.
- Infrastructure resilience: systems are robust yet flexible (modular, adaptive)

Renewable
- Refers to sustainable water and energy cycles:
- Using renewable energy for pumping, treatment, and distribution.
- Ensuring water use is within the limits of natural recharge (e.g., groundwater sustainability).
- Promoting circular economy approaches (reuse, recycling, recovery of resources from wastewater).

Organic
- Refers to working with natural processes rather than against them:
- Nature-based water treatment (constructed wetlands, soil infiltration, biofilters).
- Organic agriculture linked to water efficiency and soil-water-ecosystem health.
- Avoiding harmful chemicals and prioritizing biological/eco-hydrological methods.

Nexus
- Refers to integration and interdependence:
- The water–energy–food–climate nexus (no sector can be managed in isolation).
- Social–ecological nexus: how communities and ecosystems are mutually dependent.
- Governance nexus: connecting stakeholders across sectors and scales.
