Deltas are complex environments, consisting of a patchwork of different ecosystem types and land uses. Stakeholder perspectives and interests are equally diverse. We help integrate knowledge about ecosystem values and local risks and solutions into planning processes and investment decisions. With this in mind our delta initiatives focus on the development of integrated approaches to manage water, nature and economic development in deltas in disaster-prone regions and countries. Deltas in which we work include the Rufiji Delta, Tana Delta, Senegal delta, and the Inner Niger delta.
