Scenarios are valuable tools that could support decision making under deep uncertainty, nevertheless, their potential remains untapped. The paper explores whether participatory scenario construction in the form of stories coupled with the Intergovernmental Panel on Climate Change (IPCC) 2100 projections may contribute to increased utility of the scenarios and projections for climate-induced risk reduction, in the Nile Basin. The Nile River is 6,695 kilometres long and covers a basin area of 3.18 million square kilometres (one-tenth of the African land mass). The basin is highly susceptible to climate-change induced disasters. According to the IPCC, there is high confidence that the Basin will suffer from severe shifts in biome distribution, compounded water stress, degradation of marine life and reduced crop productivity. There is also medium confidence that the Nile Basin will experience: severe decline in livestock, significant increase in vector and water-borne diseases, undernutrition, increased migration and sea level rise. The basin is already experiencing some of these key risks, on the other hand, their impact in the next 30 to 35 years is deeply uncertain. The findings of this paper are based on four scenarios, namely: Kazuri, Miskeen, Umoja and EjoHeza and data collected from two forums that were held in Jinja, Uganda and Nairobi, Kenya. The forum participants were a multi-disciplinary team of national and international stakeholders. The paper concludes that coupling Nile Basin storylines with the IPCC 2100 projections, proved to be an effective tool in increasing the utility of the scenarios and projections, for purposes of disaster risk reduction. Future work will entail analysing the uptake of the scenarios to resolve deadlocks and enhance cooperation.

Nile Basin policy makers, at all levels, are constantly making quick decisions to address emergencies. The decisions are made in the context of a complex, uncertain, ever-changing and highly volatile basin. However, for these decisions to take into account future uncertainties, like climate-change induced disasters, policy makers need to enhance their capacity in strategic foresight. Strategic foresight helps them make more robust decisions that take into account deep uncertainties and thus buffer the basin from future natural disasters. The authors explore the contribution of serious gaming in enhancing the Nile Basin policy makers' capacity on strategic foresight. They present the findings from the application of a game-based, experimental study of a serious game known as WeShareIt. WeShareIt was played in Nairobi on 22 October 2015 by 11 participants from the Kenyan Ministry of Water and Irrigation and Moi University Centre for Public Sector Reforms. Data on the added value and contribution of the game to increased strategic foresight and disaster risk reduction were collected using pre-game, in-game and post-game questionnaires, together with a debriefing session and observations. The analysis shows that strategic foresight is an important element for effective disaster risk reduction. Observations in the game-based intervention provided evidence that the participants engaged in short term quick decision making and were not prepared for life-threatening natural disasters. The results of the experiment support the conclusion that serious gaming may be an effective and promising method for enhancing the capacity of policy makers on strategic foresight so as to prepare them for future climate induced natural disasters.
