“…Several very recent works in 2020 alone from many places internationally have looked at climate adaptation challenges (Alamanos et al, 2020;Baah-Kumi and Ward, 2020;Burek et al, 2020;Carolus et al, 2020;Dawoud, 2020;Do et al, 2020;Exposito et al, 2020;Goncalves et al, 2020;Graveline, 2020;Konapala and Mishra, 2020;Maneta et al, 2020;Meng et al, 2020;Pakhtigian et al, 2020;Sabbaghi et al, 2020;Slater et al, 2020;Tran et al, 2020;Turner et al, 2020).…”

Successful climate adaptation needs to sustain food, water, and energy security in the face of elevated carbon emissions. Hydroeconomic analysis (HEA) offers considerable potential to inform climate adaptation plans where water is an important element of economic activity. This paper's contribution is to identify how HEA can inform climate adaptation plans by minimizing economic costs of responding to climate induced changes in water supplies. It describes what HEA is, why it is important, how researchers implement it, who has made significant contributions, and places where it has informed policy debates. It also describes future directions for the use of HEA to guide climate adaptation.

The world's water resources are continuously facing challenges in fulfilling the needs of increasing agricultural water demand with finite or diminishing resources. Therefore, it is important to quantify the amount of irrigation water required to attain sustainable yield at a local, regional, and global level, especially in arid and semi-arid regions. This is mostly quantified by using agro-hydrological or agricultural models. The advances in simulation models and several options incorporated in them allow catchment/site-specific application of irrigation water to depict the field management practices undertaken by farmers. The objective of the present work is to provide a review of the simulation of irrigation water demand at catchment scale by agro-hydrological and agricultural models. This paper discusses the different types of models, their dimensions, and the hydrological and agricultural process models incorporated into them. Additionally, this review provides an overview of how irrigation can be scheduled, how water is applied, and from which sources irrigation water can be extracted by the considered models, taking horizontal hydrological connectivity into consideration. Adding to the model review, seven different fields of innovative case studies are covered. Many agricultural models have been applied in a regional context without simulating horizontal hydrological fluxes, but only a few hydrological catchment models provide full support of both irrigation and plant growth simulation, which are important for the simulation of future crop yield under different climatic and agricultural management scenarios.

“…The authors quantified the tradeoffs between hydropower, irrigation, and fisheries under different operation and hydrological conditions, with a scenario-based approach, which is limited in capturing the broad spectrum of hydrological uncertainty. Finally, a review of the hydro-economic modeling for water-policy assessment [33] highlights that while most hydro-economic models assume perfect foresight, water managers cannot perfectly predict water availability and must deal with risks in decision-making.…”

“…Considering the presented knowledge gaps, this paper brings in a contribution to the evaluation of water-energy-food nexus tradeoffs with a combination of (a) dynamic accounting of water flows and marginal water use values (varying in space and time) and (b) reliability analysis through a state-of-the-art explicit stochastic optimization model to account for hydrologic uncertainties. This addresses previous limitations as the deterministic, perfect foresight in [31], the scenario-based approach in [32], the decision-making risks in [33], and the constant willingness-to-pay for water in [48].…”

Given its potentialities and characteristics, energy generation, food production, and water availability have a strong interdependency and correlation. Water is needed to produce energy and food, while energy is required to produce water and food. This nexus brings several challenges when scarce water resources must be allocated among competing uses, often in the form of unexpected tradeoffs. Addressing those challenges requires knowledge about the water–food–energy nexus and the associated tradeoffs to support water allocation and management decisions. Those tradeoffs are still not properly understood in the uncertain and stochastic context of water availability. When not properly accounted for, the results are conflicts, loss of investments, environmental impacts, and limited effectiveness of sectoral policies, all of which undermine a country’s development model relying on water and energy security. This paper addresses the competitive uses of recent irrigated agriculture expansion and existing hydropower production in a Brazilian watershed with water conflicts, assessing the economic tradeoffs and water values between energy and irrigated agricultural production under uncertainty. An explicitly stochastic hydro-economic model is used to determine water’s economic value and its variation in space and time. Results indicate that the agricultural benefits outweigh the potential energy losses, and the best course of action should explore an economically compensated reallocation strategy, upon negotiation among users, rather than imposing water supply cutbacks to the agriculture sector.
