Action Platform for Source-to-Sea Management | SIWI - Leading expert in water governance

The source-to-sea approach recognizes that what we do on land and in rivers, lakes and aquifers can have impacts further downstream, along coasts and in the ocean. By taking these linkages into account, the approach applies a holistic view of the source-to-sea system, which will result in greater benefits for the entire system.

The Action Platform for Source-to-Sea Management (S2S Platform) is a multi-stakeholder initiative to exchange and generate knowledge, and support joint action for improved management of land, water, coastal and marine linkages. The S2S Platform strengthens partnerships between sectors and expands the understanding of source-to-sea challenges and of the solutions that will lead to sustainable development. It builds commitment so that policies and finance stimulate source-to-sea action on the ground.

The S2S Platform is open to organizations committed to holistic management of land, freshwater, coasts and the ocean. The Platform Secretariat is hosted and coordinated by the Stockholm International Water Institute (SIWI).
