Nexus in Asia // Water-energy Nexus in China's Electric Power System

By Saige Wang, Tao Cao, and Bin Chen. The electric power system is water–intensive, which aggravates the water scarcity of China. Deeper understanding of the role of electric transmission systems coupling with virtual water flows is critical for sustainable development of China.

 In this study, the flux and direction of virtual water within power system were firstly analyzed. Water scarcity index (WSI) was also incorporated to evaluate the virtual scarce water flows. Then, the authors calculated the hybrid electricity flux by multiplying electricity flux with its proportion of total electricity consumption to elucidate the significance of flux on the node's electricity supply. Finally, the authors studied the virtual scarce water flow network and hybrid electricity flux network via throughflow analysis to shed light on the nexus within the power system.

The results show that electricity inflows bring in 27.99 GL of virtual scarce water concurrent with 10.865 TW h of electricity, and 47.47 GL of virtual scarce water concurrent with 15.072 TW h of electricity into the north and central regions of China. It can be concluded that a large volume of virtual scarce water (16.3 GL) is transferred via the electric power system, mainly from inland areas to coastal areas, which is roughly the opposite of the distribution of China's water resources.

By doing this, the authors aim to evaluate the energy-water nexus rate in the electricity power system to balance the tradeoff between electricity supply and the regional inequity of water resources.

Nexus Modelling // Towards Ranking the Water–Energy–Food–Land Use–Climate Nexus Interlinkages for Building a Nexus Conceptual Model with a Heuristic Algorithm

By Chrysi S. Laspidou, Nikolaos Mellios and Dimitris Kofinas. In this article, a practical heuristic approach for gaining a systemic and contextual perspective on nexus component interlinkages is presented, by building on a simple three-point typology of interactions. The approach is simple and can be applied in any case study a nexus analysis is pursued, regardless of data availability.

A Nexus for Basin Organisations in the Sahel // Multisectoral comparison: OMVS - LCBC - NBA

By Luca Ferrini (Project Manager, Nexus Regional Dialogue Programme Niger Basin) and Lucia Benavides. This article provides a comparative analysis about the level of integration of different sectors within the mission statements of three River Basin Organisations in the Sahel: the Senegal River Basin Development Authority (OMVS by its French acronym), the Lake Chad Basin Commission (LCBC) and the Niger Basin Authority (NBA). It further stresses different focus areas of the mission statements,...
