The adoption and implementation of an Integrated Water Resources Management Plan for the Orange River still requires a substantial amount of work in order to bring all four these states on the same level and committed to such a strategy. This will involve both the national (within the four states) and on the inter-state levels. The latter will need a suitable international legal instrument. The ORASECOM Agreement may be a starting point for cooperation on the Orange River but is not adequate for the stated purpose. An IWRMP for the Orange will have to be conceptually sound. There should be prior agreement on the content for the whole scheme and how it will be implemented on both the inter-state (regional) and intra state levels. The intra state dimension will require national legislation which will pursue the same objectives and be fully in line with the international plan. The outcomes should be complementary and in harmony. National measures should be fitted into the regional plan and jurisdictional issues should be synchronized. This will require that all national legislation speak the same language on the principles involved.
