“…As pointed out by Graveline [37], the regional-scale modeling permits the reduction of data needed and ensures the quality of data employed. At the same time, field-level water management strategies play an important role as basic elements for water use efficiency [43].…”

“…This allows exploring the optimal solutions from a policy-makers perspective, especially when sufficient homogeneity is observed across the region and it can be considered as a large farm [37]. Each study area should be large enough to contain a significant number of farms, while the focus on an "irrigation unit" would avoid introducing sources of variation related either to agro-climatic or economic conditions [38].…”

Due to the changing climatic and environmental conditions, modifications in agricultural and water policies have been made, and irrigated agriculture has to face the challenge of making a rational and optimal use of the water resource effectively available. This urges rice farming, strongly and traditionally linked to water, to change the modalities for the use of the resource. If on one hand water saving techniques should be preferred, a different water management in paddy fields may lead to lower yields and higher production costs, with consequent repercussions on farm incomes. The paper recognizes the disagreement between environmental and economic concerns and aims at contributing to the discussion about how to reconcile them by adopting alternative irrigation strategies. From this perspective, a multi-objective linear optimization model is used to explore the trade-offs between conflicting objectives in a rice-growing area in Northern Italy. The model returns the optimal allocation of land subject to three different irrigation strategies, as those previously performed in experimental fields; in addition, a scenario analysis is run to simulate reduced resource availability. Results demonstrate the key role of prioritizing one objective over the other, while introducing cultivars more suitable for dry cultivation enables enlarging the frontier of optimal solutions.

“…In the case of agricultural systems, the agents' decisions include crop selection and land management (e.g., fertilization), water application, and investments in capital stock. This complex decision‐making problem involves multiple inputs and is often simplified by assuming each possible combination of crops and management techniques as a unique crop x i (Graveline, ). This assumption allows the decision‐making problem to be reduced to a choice on the crop portfolio ( x ) within a domain ( F ( x )), where the crop portfolio ( x ) is a vector representing the land share devoted to each individual crop ( x i ) .…”

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.

“…These 2 elements shaped different types of implementation activities that, during the second part of the 4‐y project, will aggregate the analysis of the water vulnerabilities (phase 1) and the results of the validation of technologies (phase 2): Two decision support tools (DSTs) will be developed and adapted to the selected basins (Akter et al ; Hamouda et al ): the first will support the analysis and selection of WW treatment technologies and facilitate their integration into basin‐scale WW management strategies, whereas the second will integrate the project's irrigation technologies into basin‐scale strategies for water and land management in agriculture. The second DST will be based on the development of and calibration to the 3 selected basins (Table ) of an integrated hydro‐agro‐economic model capable of optimizing cropping patterns and water allocation (D'Agostino et al ; Esteve et al ; Graveline ). The DSTs will be used to develop strategies for WW management and for agricultural water and land management, tailored for the 3 selected hydrological basins (Table ). The WW management strategies, aimed at maximizing the amount of irrigation‐quality treated WW produced, will include elements such as the addition of a WW technology to treat the effluent of an existing WW treatment plant or the identification of economic instruments that enhance the implementation of innovative WW treatment technologies.…”

Mediterranean-African countries (MACs) face a major water crisis. The annual renewable water resources are close to the 500 m /capita threshold of absolute water scarcity, and water withdrawals exceed total renewable water resources by 30%. Such a low water availability curbs economic development in agriculture, which accounts for 86% of freshwater consumption. The analysis of the current situation of wastewater treatment, irrigation, and water management in MACs and of the research projects targeted to these countries indicates the need for 1) an enhanced capacity to analyze water stress, 2) the development of water management strategies capable of including wastewater reuse, and 3) development of locally adapted water treatment and irrigation technologies. This analysis shaped the MADFORWATER project (www.madforwater.eu), whose goal is to develop a set of integrated technological and management solutions to enhance wastewater treatment, wastewater reuse for irrigation, and water efficiency in agriculture in Egypt, Morocco, and Tunisia. MADFORWATER develops and adapts technologies for the production of irrigation-quality water from drainage canals and municipal, agro-industrial, and industrial wastewaters and technologies for water efficiency and reuse in agriculture, initially validated at laboratory scale, to 3 hydrological basins in the selected MACs. Selected technologies will be further adapted and validated in 4 demonstration plants of integrated wastewater treatment and reuse. Integrated strategies for wastewater treatment and reuse targeted to the selected basins are developed, and guidelines for the development of integrated water management strategies in other basins of the 3 target MACs will be produced. The social and technical suitability of the developed technologies and nontechnological tools in relation to the local context is evaluated with the participation of MAC stakeholders and partners. Guidelines on economic instruments and policies for the effective implementation of the proposed water management solutions in the target MACs will be developed.
