From the above and beside the securing of water rights for the national mining industry, the irrigation clusters scattered as if pearls along the Orange River's N bank are of an obviously unrenouncable significance for the Namibian agricultural production. In any case, it is clearly of utmost importance for Windhoek to secure the possession of the N flood plain by a boundary accord to be reached as soon as possible. This should determine as a minimal solution the border line finally along the low water mark, or, certainly more advantageous for the country, following the rivers median line. Even more so because, in spite of the high costs this would entail due to the lack of infrastructure in the inaccessible Orange gorge, the future extending potential of the irrigation schemes on the N bank are be estimated at least on 7800 ha (Otzen 1989) which is six times the developed irrigation area at the present stage and more than the actual overall Namibian irrigated cultivation area.
