“…At a more fundamental level, the question of what constitutes an "equitable and reasonable utilization" of transboundary water management is a rather challenging one. In spite of these challenges, however, research progress in domains such as cooperative game theories (Gintis, 2000;Madani and Dinar, 2012) and morally informed allocation and optimization techniques (Ciullo et al, 2020) illustrate potential opportunities and operationalization mechanisms of distributive justice in transboundary water resources management. In value optimization techniques, for instance, the role of distributive justice is illustrated through explicitly applying ethical principles to how optimization problems are formulated in terms of objectives and constraints (Tian et al, 2019;Ciullo et al, 2020).…”

The importance of cooperation on transboundary waters is stated as a target in the United Nations 2030 Agenda for Sustainable Development Goals (SDG6: water). Cooperation on transboundary water management is critical, particularly because it concerns issues across multiple states, SDGs and targets regarding agriculture, energy, ecosystems, climate adaptation, health, and peace and security. The percentage of transboundary basin area within a country that has an “operational arrangement” for water cooperation is used as the main indicator of such cooperation in the SDGs for “equitable and reasonable use“ of water resources (SDG 6.5.2). However, no clear criteria and explanation are available for what exactly constitutes an “equitable and reasonable use” in any such “operational arrangements.” Furthermore, it is understandable that any such arrangements may be shaped by differences in historical, legal, and political contexts and hence may be inherently unjust. Here, we highlight the limitations of SDG indicators, particularly SDG 6.5.2, to monitor equity of resource sharing in transboundary river systems. Using Walzer’s theory of morality of the state and cosmopolitanism as a framework, we examine the Nile basin as a case study to demonstrate the shortcomings of current SDG criteria and indicators. Our article contributes ideas of “operationalizing” theoretical justice toward a more equitable water management in transboundary rivers.

“…The total penalty is the result of penalization of the water excess in river segments (floods, T), shortage in river segments (Q), shortages in allocation to demand nodes (S t− ), excess allocation to demand nodes, shortage in reservoirs (SH), overflow in reservoirs (OF), flooding in demand segments (S t+ ), shortage in demand segments (MinXD), and overflow in demand segments (MaxXD) whereby each component is associated with a specific penalty value. Equations (2) and 3, model the flow balance constraints; water coming in a node plus the change in water present in the node must equal to the volume of water going out from that node. Equation (2) establishes this constraint for a transfer node, whereas Equation 3deals with the flow balance of a reservoir node.…”

“…Between hydropower generation and food production, the so-called water-energy-food-nexus (WEF-nexus), Sharma [1] showed the benefits of using reservoirs to mitigate this nexus thereby increasing agricultural production, as well as energy production, and even avoiding floods by controlling water levels. Liu et al and Alam et al [2,3] conducted research aimed at optimizing the WEF-nexus based on a cascaded reservoir system prioritizing agriculture and reducing The length of the Machángara River is about 37 km. It crosses the capital of the Azuay province, Cuenca [7].…”

The allocation of water flowing through a river-with-reservoirs system to optimally meet spatially distributed and temporally variable demands can be conceived as a network flow optimization (NFO) problem and addressed by linear programming (LP). In this paper, we present an extension of the strategic NFO-LP model of our previous model to a mixed integer linear programming (MILP) model to simultaneously optimize the allocation of water and the location of one or more new reservoirs; the objective function to minimize only includes two components (floods and water demand), whereas the extended LP-model described in this paper, establishes boundaries for each node (reservoir and river segments) and can be considered closer to the reality. In the MILP model, each node is called a “candidate reservoir” and corresponds to a binary variable (zero or one) within the model with a predefined capacity. The applicability of the MILP model is illustrated for the Machángara river basin in the Ecuadorian Andes. The MILP shows that for this basin the water-energy-food nexus can be mitigated by adding one or more reservoirs.

“…Today, the water-energy-food nexus approach has been utilized via different dimensions in several studies under various objective functions in the form of optimization models (Jalilov et al, 2016;Dhaubanjar et al, 2017;El-Gafy et al, 2017;Stamou and Rutschmann, 2018;Zhang et al, 2018;Gonz´alez-Bravo et al, 2018;Si et al, 2019;Hu et al, 2019;Li et al, 2019;Liu et al, 2019;Zhou et al, 2019;Namany et al, 2019;Nie et al, 2019;Niu et al, 2019;Wicaksono et al, 2019;Sun et al, 2020;Ji et al, 2020;Falconer et al, 2020;Esmaeli and Roshandel, 2020;Yu et al, 2020;Medina-Santana et al, 2020;Sadeghi et al, 2020;Radmehr et al, 2021). For instance, Jalilov et al (2016) attempted to optimally allocate water resources in the Amu Darya River Basin using the concept of the water-energy-food approach through maximizing the net present value of the total benefits of agriculture and Hydroelectricity generated in the Rogun Dam.…”

Accomplishing the objectives of optimal and sustainable management in the agricultural sector is increasingly getting complicated, which includes increasing the sustainable productivity of water and energy resources, ensuring food security, decreasing contaminations from fertilizers and chemical pesticides, and environmental destruction. The present research deals with designing the relationships between the water-energy-food (WEF) nexus approach with economic and environmental objectives to accomplish the aforementioned objectives. Hence, a multi-objective programming model was developed to maximize the water-energy-food nexus index and farmers' gross margin, minimize the use of chemical fertilizers (nitrogen and phosphate), and minimize the use of chemical pesticides (herbicides) by considering the balancing constraint to groundwater resources. Afterward, the proposed multi-objective model was solved using the augmented ε-constraint method, and then the total of strong and efficient Pareto solutions was extracted. Then, the best solution was chosen using the TOPSIS method and assigning a weight of equal importance to the desired objectives. The irrigation network of Jiroft plain in Kerman province in Iran was chosen as the study area to implement such a system. The obtained results indicated that the optimal and sustainable management in the agriculture sector can be hopeful using the proposed approach in the current research. On the other hand, the results revealed that despite considering the economic objective in the proposed system, the farmers' profits can be significantly decreased. Thus, the realization of optimal and sustainable management in the agricultural sector is not possible without the implementation of policies for increasing the economic incentive of farmers.
