“…Where changes are marginal or happen at a small scale, these feedback can be ignored (as is the case study explored in this paper, since the economic relevance of the RMBM in the wider basin and regional scale is limited). However, where changes are not marginal, large‐scale structural changes in the crop portfolio can lead to impacts on prices through feedback into the output of economic sectors at a regional and supraregional scale (Hertel & Liu, ). As the economy transitions toward a new equilibrium, commodity prices, including those relevant for agriculture, will change, thus affecting irrigators' decisions.…”

Rationalizing Systems Analysis for the Evaluation of Adaptation Strategies in Complex Human‐Water Systems

Water resources management is a nontrivial process requiring a holistic understanding of the factors driving the dynamics of human‐water systems. Policy‐induced or autonomous behavioral changes in human systems may affect water and land management, which may affect water systems and feedback to human systems, further impacting water and land management. Currently, hydro‐economic models lack the ability to describe such dynamics either because they do not account for the multifactor/multioutput nature of these systems and/or are not designed to operate at a river basin scale. This paper presents a flexible and replicable methodological framework for integrating a microeconomic multifactor/multioutput Positive Multi‐Attribute Utility Programming (PMAUP) model with an eco‐hydrologic model, the Soil and Water Assessment Tool (SWAT). The connection between the models occurs in a sequential modular approach through a common spatial unit, the “hydrologic‐economic representative units” (HERUs), derived from the boundaries of decision‐making entities and hydrologic responsive units. The resulting SWAT‐PMAUP model aims to provide the means for exploring the dynamics between the behavior of socio‐economic agents and their connection with the water system through water and land management. The integrated model is illustrated by simulating the impacts of irrigation restriction policies on the Río Mundo subbasin in south‐eastern Spain. The results suggest that agents' adaptation strategies in response to the irrigation restrictions have broad economic impacts and subsequent consequences on surface and groundwater hydrology. We suggest that the integrated modeling framework can be a valuable tool to support decision‐making in water resources management across a wide range of scales.

“…However, these results indicated that countries like Sudan, Ethiopia, and Ethiopia, and Kenya have a higher WF. Water is intertwined with a variety of economic activities, and it has many diverse channels by which it influences human and economic development [102]. The advancement of the socioeconomic and environmental processes cannot work without the help of a long-term WEFBH scheme [103].…”

Insights on Water and Climate Change in the Greater Horn of Africa: Connecting Virtual Water and Water-Energy-Food-Biodiversity-Health Nexus

Water is the key limiting factor in socioeconomic and ecological development, but it is adversely affected by climate change. The novel virtual water (VW) concept and water, energy, food, biodiversity, and human health (WEFBH) nexus approach are powerful tools to assess the sustainability of a region through the lens of climate change. Climate change-related challenges and water are complex and intertwined. This paper analyzed the significant WEFBH sectors using the multicriteria decision-making (MCDM) and analytic hierarchy process (AHP) model. The AHP model demonstrated quantitative relationships among WEFBH nexus sustainability indicators in the Greater Horn of Africa countries. Besides, the net VW imports and water footprints of major staple crops were assessed. The composite WEFBH nexus indices varied from 0.10 to 0.14. The water footprint of crops is increasing period by period. The results also revealed that most countries in the study area are facing WEFBH domains unsustainability due to weak planning or improper management strategies. The strong policy constancy among the WEFBH sector is vital for dissociating the high-water consumption from crop production, energy, environmental, and human health system. Thus, this study enhances insights into the interdependencies, interconnectedness, and interactions of sectors thereby strengthening the coordination, complementarities, and synergies among them. To attain sustainable development, we urgently call all public and private entities to value the amount of VW used in their daily activities and design better policies on the complex WEFBH nexus and future climate change.

“…Freshwater supply has been altered worldwide due to human-induced changes, like habitat degradation, anthropogenic subsidence, climate-related risks, and the increasing disproportionate water consumption [1][2][3]; causing water scarcity and salinization in some regions and flooding in others [4][5][6]. Besides, the agricultural activity prompts natural water overexploitation and pollution [7].…”

The growing need for alternative water resources for irrigation has led to advanced technological developments, which are addressing some of the challenges that our planet is facing regarding the water supply. The Canary Islands Archipelago (Spain) is a singular territory with several years of desalination experience while using desalinated seawater (DSW) for agricultural purposes. The current paper will address the conducted research of one of the case studies done into the Horizon 2020 project MAGIC, with the aim of analyzing the use of DSW for crop production in the Southeast of Gran Canaria Island. A methodology of surveying farmers in the area has been put in practice, as well as an assessment of potential soil degradation risks that are related to DSW irrigation (with fifteen years of DSW data). Additionally, local good practices to improve the DSW quality for irrigation are discussed. This study demonstrates an excellent endorsement of the surveyed farmers in the studied area regarding the use of DSW for irrigation: the strategy of combining this type of water with other water resources, such as groundwater and/or reclaimed water is very frequent and it can guarantee water and food security in the island’s territory.
