Access to cross-border water sources in the African regions of the Nile River, Zambezi River, and Lake Turkana Basins becomes less certain as global population, human consumption, and climate change increase. Uncertainty during periods of high demand for water in agro-dependent economies creates circumstances of water stress, where social stability is low as stakeholders compete over scarce water sources. Longstanding traditions of political power, such as colonial rule and the status of regional superpowers, reinforce the unequal resource distribution. All three regions encounter water stress in the form of floods or droughts. They rely on dam projects that modify water distribution and basin agreements that reallocate political power to manage stress. The basins vary, however, in conflict intensity and effectiveness of water management strategies. The Nile River Basin exhibits low-intensity conflict and has institutionalized collaborative management strategies; the Zambezi River Basin demonstrates medium-intensity conflict with theoretically collaborative initiatives that fall short in practice; the Lake Turkana Basin exemplifies high-intensity conflict, lacking collaborative agreements. In order to address the discrepancy in outcomes, this study asks: what factors contribute to the intensity of conflict surrounding water stress? And, to what extent are water management practices effective in promoting cooperation and preventing conflict? The study concludes that the most intense conflicts occur in rural localities, where social instability is high and resource distribution is uneven. Collaborative agreements and international involvement in water management initiatives increase social stability and decrease conflict intensity by institutionalizing equitable distribution of water in a changing environment.

The need for water management on hydrological boundaries is mainly triggered by the growing competition for water or by the need to cooperate in an upstream downstream relation. For an institution operating on political boundaries, not coinciding with the boundaries of the river basin, it is very difficult to allocate or prioritise water or carry out flood control measures. A system of water management on political boundaries will induce the respective authorities to either monopolise the water supply sources within its area and to transfer the problem of flooding to downstream. In this article it is attempted to explore the major transboundary issues that need to be addressed in the whole Brahmaputra River basin. Sharing of resources, sharing of basic data and information and protection and preservation of ecosystem are identified as three major issues. In this context, controversial legal issues between the riparian nations in the past were also analysed which has triggered the scope for integrated approach to manage the Brahmaputra River basin. In the later part of the article, a critical analysis was made to understand the principles, approaches and instruments to address the above problems. Finally, some legal materials are presented which could be used as a basis for solving the major river basin issues.Key words: water management; diversifying water supply sources; water management strategies; NepalJournal of the Institute of Engineering, Vol. 7, No. 1, July 2009, pp. 135-141doi: 10.3126/jie.v7i1.2072

River basin planning in Bolivia is a relatively new endeavor that is primed for innovation and learning. One important learning opportunity relates to connecting watershed planning to processes within other planning units (e.g., municipalities) that have water management implications. A second opportunity relates to integrating watershed management, with a focus on land-based interventions, and water resources management, with a focus on the use and control of surface and groundwater resources. Bolivia’s River Basin Policy and its primary planning instrument, the River Basin Master Plan (PDC in Spanish), provide the relevant innovation and learning context. Official guidance related to PDC development lacks explicit instructions related to the use of analytical tools, the definition of spatially and temporally dis-aggregated indicators to evaluate specific watershed and water management interventions, and a description of the exact way stakeholders engage in the evaluation process. This paper describes an effort to adapt the tenets of a novel planning support practice, Robust Decision Support (RDS), to the official guidelines of PDC development. The work enabled stakeholders to discern positive and negative interactions among water management interventions related to overall system performance, hydrologic risk management, and ecosystem functions; use indicators across varying spatial and temporal reference frames; and identify management strategies to improve outcomes and mitigate cross-regional or inter-sectorial conflicts.

Efficient N management practices usually involve many potential strategies, but always involve choosing the correct amount of N and the coupling of N management to efficient water management. Nitrogen management strategies are integral parts of improved production practices recommended by land-grant universities such as the Institute of Food and Agricultural Sciences, Univ. of Florida. This paper, which draws heavily on research and experience in Florida, outlines the concepts and technologies for managing vegetable N fertilization to minimize negative impacts on the environment.
