Regular flooding is an essential event for the delta because it supports the ecological system that provides the foundation for tourism, biodiversity and livelihoods. Through promoting regional cooperation and sharing benefits, OKACOM aims to reduce unsustainable activities in all three countries and prevent development activities that exceed the constraints of the system, while enhancing the ecosystem services of the basin for the benefit of all riparian countries (OKACOM, 2015). The institution strives to deepen cooperation to ensure that the three countries define and respect those system thresholds, or the upper limits of sustainable abstraction. Historical political alliances have formed trust, which is still a key success factor, primarily because those alliances encourage a shared vision among the countries, facilitating water policy in a way that preserves the ecological integrity of the basin and protects the system's socioeconomic benefits.
