EJERS, European Journal of Engineering Research and Science Vol. 4, No. 6, June 2019 A Conceptual Framework for Organization of River Basin Development and Management in Nigeria Bukar Abba Gana, Isah Funtua Abdulkadir, Hassan Musa, and Tijjani Garba irrigation farming, fishing, site attraction, as well as Abstract—River Basin Development Authorities (RBDAs) in diversion of water for augmentation action to areas of Nigeria were established since 1976 and they operate shortage, (Gana et al., 2018). River basin management is mechanized and capital intensive programmes. All the 12 one of the biggest challenges of the 21st century. River RBDAs operate as separate Authorities, each with separate basins sustain ecosystems. They are the paramount source of administrative and operational autonomy, but sharing the Basin Resources of the 8 Hydrological Areas. However, their water for households, agriculture and industry, and fulfil performance was generally described as disappointing. This many non-consumptive uses. Globally, many countries, study first reviewed the existing organization of the 12 RBDAs including Nigeria, have made efforts to harness the resource in Nigeria. Thereafter, one of the 8 Hydrological Areas – the potentials in river basins in their areas to facilitate the Komadugu-Yobe Basin (KYB) – which is the major inland development process. The first comprehensive attempt drainage system in Nigeria was purposely selected for detailed started in the Tennessee Valley of United States of America study. Information on its major streams, tributaries and the main river; the hydrological area as well as the RBDAs sharing in 1933. During the years of reconstruction, after the Second resources of the basin area, was gathered using ArcGIS version World War, the Tennessee experience gained widespread 10.0 and Erdas Imagine 9.2 software, as well as topographical acceptance among the developed and the developing and hydrological maps. This was processed and analyzed based countries. Different strategies were used to achieve desired on the principles of Stream Ordering and Logical Framework objectives. The degree of successes realized differed from Analysis. The findings revealed that in establishing the RBDAs, country to country, depending on the effectiveness of the basin-wide consideration of their sphere of operation was not taken into account. Dams were constructed before establishing strategies employed. the RBDAs. Runoff waters and spill ways were poorly In Nigeria, the River Basin Development Authorities, controlled leading to flooding during rainy season and reduced (RBDAs) were to principally accelerate agricultural and water supply downstream during dry season, with serious rural development, and also to boost food and industrial environmental and socio-economic problems in the basin area. crop production (Baba, 1985). But, the existing organization It was concluded that the RBDAs in Nigeria were poorly for river basin development and management is adjudged a organized and have consequently failed to accelerate agricultural and rural development, and have also failed to façade of river basin development, (Adams, 1985; Barrow, boost food and industrial crop production as expected. The 1998) due to major structural problems and resulting need was established for effective organization of River Basin disappointing performance. The development of some major Development and Management to improve their performance. dams or irrigation projects preceded the establishment of the To achieve this, a Conceptual framework for Integrated River RBDAs in a number of river basins, notably in Sokoto, Basin Development and Management was developed for Hadejia, Jama’are, Chad, Gongola, (Adams, 1985) and, adoption by river basin managers and other relevant stakeholders in Nigeria and around the globe to improve Ogun and Imo, (Amangabara, G T 2015; Elechi, E E., performance. 2006). Projects were designed without reference to the needs and potentials of the basin as a whole. Concern about lack of Index Terms—Conceptual Framework, Hydrological Areas, environmental appraisal and knowledge of the downstream Integrated River Basin Development and Management, ecological impacts of dam construction in Nigeria is Komadugu-Yobe Basin, River Basin Development Authorities adversely significant, (Shettima, 1997; Wallace, 1980).
