“…Both issues have been the subject of difficult, ongoing negotiations between Egypt, Ethiopia, and Sudan. Previous studies of the GERD and HAD operations have sought to identify tradeoffs between different riparian objectives, and to understand the risks and rewards of basin-wide cooperation [12][13][14][15][16][17][18][19][20][21][22][23] . These efforts provide important insights that will inform multilateral agreements and create a structure for addressing the significantly different interests in the basin.…”

Understanding and managing new risks on the Nile with the Grand Ethiopian Renaissance Dam

When construction of the Grand Ethiopian Renaissance Dam (GERD) is completed, the Nile will have two of the world’s largest dams—the High Aswan Dam (HAD) and the GERD—in two different countries (Egypt and Ethiopia). There is not yet agreement on how these dams will operate to manage scarce water resources. We elucidate the potential risks and opportunities to Egypt, Sudan and Ethiopia by simulating the filling period of the reservoir; a new normal period after the reservoir fills; and a severe multi-year drought after the filling. Our analysis illustrates how during filling the HAD reservoir could fall to levels not seen in recent decades, although the risk of water shortage in Egypt is relatively low. The new normal will benefit Ethiopia and Sudan without significantly affecting water users in Egypt. Management of multi-year droughts will require careful coordination if risks of harmful impacts are to be minimized.

“…An applied model that confirms this result was recently published by Dinar and Nigatu (2013), who modelled the possible gains from trade among three countries that share the Blue Nile. Their results show that such trade-agreements are not core-stable, indicating the fragility of cooperation in transboundary basins (see also Nigatu and Dinar, 2016). Summarizing, our results put recent research on river sharing in a broader perspective and demonstrate that the benefits of cooperative water use may not be reaped easily.…”

We analyse coalition stability in a game with a spatial structure. We consider a set of agents located along a river who abstract scarce water for their own benefit. Agents may enter an agreement to mutually acknowledge property rights in river water as a prerequisite for water trade. We find that the potential benefits of water trade may not be sufficient to make all agents in the river cooperate and sign an agreement. Specifically, a complete market for river water may not emerge if there are four or more agents along the river. This result is driven by the spatial structure of our game, in which water that is to be delivered to a downstream coalition member via the territory of an intermediate singleton can be seized.

“…Basically, direct economic losses have been caused by agriculture (crops, fishery, forestry, animal husbandry), industry, commerce, and infrastructure (roads, railways, telecommunication, and tunnels) (Wang and Zhang, 2018). The direct economic loss has been measured as physical losses and income losses (Nigatu and Dinar, 2015). Physical losses are the physical value reductions in buildings, equipment, machinery, and all type of fixed or current assets which were affected by the dam break floods (Mo, et al, 2019).…”

Dams have become a very important infrastructure that provides enormous benefits to the economy of the country. Even though dams are very important and significant structures within a country, their breaks can cause severe damage to the country’s economy, society, and environment. Other than that, it can be impacted human life by causing deaths. As a come-up strategy, early warning systems can be used to reduce the severe impacts of dam breaks. Early warning systems (EWS) have been identified as a very important tool used to save lives and properties from disasters. Hence, this paper attempts to identify the functional characteristics of an EWS that can be used to reduce the impacts of dam breaks in Sri Lanka. An extensive literature survey was conducted to achieve the primary objective of this paper. Accordingly, the paper has identified the major purposes of dams, the causes for the dam breaks, and the impacts of dam breaks on the economy, society, and the environment. Then, the paper explores the functional characteristics of the EWS which is used for dam breaks. Finally, a conceptual framework has been developed with the key literature findings of the paper in order to minimise the social, economic, and environmental impacts created by dam breaks using early warning systems in Sri Lanka. As such, this paper will be a value addition to support the country’s economy, society, as well as environment.
