The mission of Delta Alliance is:

'To improve the resilience of deltas worldwide'

 
The strategy to realize this mission is outlined in the Delta Alliance Strategic Framework, and includes the following points:

1. envisioning and defining resilience for deltas
2. measuring and monitoring resilience
3. reporting and creating pressure for improved resilience
4. providing inspiration for improved resilience
5. providing assistance for improved resilience

The Strategic Framework (pdf, september 2010) further outlines the Delta Alliance resilience strategy and declaration, milestones and objectives, organizational and network development, projects, and funding. The framework is an outcome of the scoping activities, which explored opportunities for an international delta network starting with partners in California, Indonesia, The Netherlands, and Viet Nam. As the development of Delta Alliance is a dynamic process, the strategy requires a periodic (preferably annual) review by the Advisory Committee and the International Governing Board.
