“…Regulatory approaches, such as requiring abstraction permits, have a limited impact (Bryant et al ., 2017), especially in environments where charges and/or tariffs for irrigation water are low. Common measures to modernize irrigation systems such as replacing open canal and gravity systems with pressurized irrigation systems, and irrigation and flow meter installation (Yohannes et al ., 2019, Belaud et al ., 2019, Wang et al ., 2020) will have a limited impact in areas where irrigation systems were designed and built as drip and sprinkler, and pressurized irrigation systems. If systems lack effective irrigation control and flow gauges, and soil‐water monitoring equipment or require modernization due to irregular maintenance in the past, addressing these issues will result in considerable water and energy savings (Cvejić et al ., 2019).…”

“…The most frequent reasons for this are spatial and environmental restrictions, low food costs, and larger costs for irrigation system construction per area unit since irrigation systems in the most favourable areas had already been put in place (Plusquellec, 2002; Belaud et al ., 2019). Throughout the world warnings regarding the low utilization of the existing LIS and unsatisfactory functioning of LIS have been voiced and efforts directed towards improving the efficiency of existing irrigation systems (e.g., Hertzog et al ., 2014; Wang et al ., 2020). Low utilization remains the central concern of contemporary irrigation development (Schultz & De Wrachien, 2002; Turral, Svendsen, & Faures, 2010; Burt, 2013; Tarjuelo et al ., 2015).…”

Large‐scale irrigation systems (LIS) are massively utilized in agriculture worldwide to ensure food security and mitigate the effect of global warming. LIS face unpredictable changes in climate, technologies, and societal tendencies during their lifetime, potentially becoming unusable or insufficient. In this case study of Slovenia, the evolution of LIS was divided into five characteristic periods in terms of motivation, mechanisms, and the key stakeholders. The heyday of LIS development in the late 1980s was followed by denationalization and privatization, and construction was replaced by measures for improving the status irrigation at the state level. Simultaneously, there was a shift in global development towards modernization as LIS should be adaptive to changes throughout their existence in order to preserve their functionality. The construction of LIS resumed less intensively in the European Union during 2007–2013, with recognition of effective LIS functioning as necessity. This study confirms that irrigation development follows the global imperative focus on more effective use of the existing LIS along with simultaneous reduction in the environmental impact of agricultural production through smarter use of water, nutrients, and plant protection products. This should be achieved by organized LIS users, increased knowledge, efficient LIS maintenance and management, and improved connections to the local markets.

“…To calculate GHG emissions related to water extraction, the volume of water to be extracted was calculated first. For this, an application efficiency of irrigation systems of 95% and an addition water extraction of 10% to compensate for evaporation losses in reservoirs and water losses in the distribution network were used [56]. The total water volume was divided between the number of boreholes, assuming each borehole draws the same amount of water.…”

Agriculture is an activity linked to the environment and has a great influence on climate change. As more and more crops are producing in less time, agricultural production is intensified and water consumption and energy demand is increasing. Since the energy consumed is not renewable, greenhouse gases (GHG) are emitted and their concentration in the atmosphere increases. The objective of this article is to apply various methodologies for the precise quantification of the carbon dioxide equivalent (CO2-eq) and GHG emissions in the management of irrigation water and energy in ten water user’s associations (WUAs) in the southeast of Spain. All the studied WUAs include irrigation facilities. This paper is based on obtained data in different water and energy audits during 2017. The concept of “irrigation water management” considered in the article covers the process from its extraction through management data to its transport and application to crops through irrigation systems, as well as the reception of water. The way in which water and energy is used to irrigate crops is taken into account. Moreover, the type of energy used for irrigation and at what moment energy is demanded influence the total amount of generated GHG emissions. The tariff periods for electricity and the water needs of the crops planted also has to be taken into account, as well as the economic emissions valuation.

“…In Lebanon, Nouri et al (2019) show that combined with mulching, drip irrigation reduces water consumption by 4.7 percent for various crops. Another study reports that by decreasing the evapotranspiration using drip-irrigation systems, water consumption can be reduced by 50 percent depending on the temperature variation (Wang et al, 2020).…”

Managing the trade‐off between groundwater resources and large‐scale agriculture: the case of pistachio production in Iran

Benefiting from historically favorable conditions (e.g. low costs, fertile land, and abundant water), pistachio producers in Rafsanjan, Iran, have flourished, with pistachio orchards and production growing dramatically since the 1970s. Today, however, the enormous increase in water consumption associated with pistachio production has severely depleted groundwater aquifers, causing widespread water shortages in the region. In this article, we develop a comprehensive system dynamics model, combining the agronomic, economic, hydrologic, and behavioral aspects to analyze the long-term implications of pistachio production. Our research contributes to the literature of agricultural water management in three significant ways: (i) it provides a validated and quantitative model exploring pistachio farming for a region; (ii) it explicitly captures behavioral decision rules associated with orchard growth and production investment; and (iii) it addresses a natural common-pool-resources problem with very long-time horizons. We consider several policies aimed at addressing the problem (e.g. water transfers, drip irrigation, financial subsidies, income tax, water pricing, and land purchasing). Our results suggest that policies that increase the effectiveness and efficiency of production (e.g. water transfer and drip irrigation respectively), albeit preferred by farmers, lead to better-before-worse results, depleting groundwater storage in the long term. Insights from the model can help policymakers have a better understanding of the unintended consequences of their policies.
