Summary: This paper assesses the conditions for hydraulic projects to be considered as an efficient option for securing water supply in agricultural areas from an environmental perspective, using the Territorial Life Cycle Assessment methodology. The study evaluates the environmental performance of different land use scenarios and the water-energy-infrastructure nexus between two types of hydraulic projects. The findings indicate that the efficiency of the scenarios varies depending on the service and land use type. The analysis also highlights the trade-offs between the two types of projects. The study underscores the importance of considering the territorial context in the environmental assessment of land planning projects.

Summary: As solar technology advances, the use of photovoltaic pumping systems (PVPSs) for irrigation has become popular in developing countries. However, the high upfront costs of PVPSs pose a financial burden for low-income farmers. This study presents a technoeconomic framework to quantify the impact of solar pump efficiency on the cost of the solar array in a PVPS, demonstrating that high-efficiency motors may lead to cost reduction despite the increased motor cost. This efficiency-driven design process can improve the cost-effectiveness of solar-powered systems.

Summary: Irrigation modernization has impacts on irrigation energy consumption and greenhouse gas emissions, leading to improved irrigation water efficiency. A scenario-decomposition-based calculation method was proposed to examine the impact of irrigation system modernization on China's irrigation energy consumption and GHG emissions at national and provincial scales. The data revealed that from 2005 to 2015, the irrigation water volume and energy consumption increased by 7.9% and 22.3%, respectively, reaching a national equivalent of 42.5 Mt CO2e in 2015. Water-energy consumption varied greatly across the country, with significantly higher irrigation energy consumption per unit volume of water and per unit area in northern provinces compared to southern provinces. Promoting water-saving irrigation technology can effectively improve China's irrigation water-energy-GHG emissions structure, enhancing irrigation efficiency without a significant increase in energy consumption. The specific conditions of each region should be considered when promoting water-saving irrigation technologies, with particular attention given to the relationship between irrigation water-energy-GHG emissions in northern provinces.

Summary: One of the main challenges in arid and semi-arid regions is the lack of water for various purposes. This research proposes a fuzzy system with multiple inputs and outputs to accurately predict water consumption in different climates. The results show that the system is efficient in irrigating crops and can save a significant amount of water.

Summary: Climate variability plays a significant role in influencing irrigation water use, with strong negative correlations observed between precipitation and irrigation withdrawals. However, temperature sensitivities vary by region and season, as do the interactive effects of temperature and precipitation on irrigation demand. Climate-induced irrigation variability is most pronounced in transitional climate zones, which are distinct from regions with the highest rates of irrigation withdrawals and represent a separate consideration from chronic overpumping.

Summary: Improving water use efficiency in agriculture is crucial for regional food security and ecological sustainability. This study developed water productivity and water efficiency indices for corn cultivation in China and examined the spatial-temporal patterns and determinants of water productivity and water efficiency. Results showed that both indices increased over time and exhibited spatial differences, with agricultural production technology improvements and crop spatial arrangement optimization playing vital roles in enhancing water use efficiency.

Summary: This study compares the energy and carbon footprints of irrigation water provided by gravity-fed irrigation networks and groundwater pumping systems. Groundwater, while only contributing 6% to total irrigation water supply in the lower Indus basin, dominates energy use and CO2 emissions. Shifting from groundwater pumping to properly maintaining gravity-fed canal systems can decrease energy use and CO2 emissions, while increasing surface water availability.

Summary: This paper discusses the water supply and utilization from a supply chain perspective, including water delivery, irrigation, crop production, and crop supply chains. These supply chains are symbiotic, with changes in crop demand, agronomic technology, and water knowledge impacting water infrastructure, irrigation technology, land use, crop production patterns, and water pricing. Evidence from California and elsewhere supports the findings of the paper.

Summary: This study analyzes groundwater systems in the south-western Birbhum district, India, and finds that groundwater irrigation can lead to decreased crop yields, degraded soil quality, and water toxicity risks for sensitive plants. By integrating multiple parameters, about 97.73-98.88% of the total area is classified as unsuitable for irrigation. The study recommends implementing measures to reduce salinity, sodicity, and harmful substances in water, as well as adopting advanced irrigation practices to prevent soil degradation and enhance crop productivity.

Summary: The increasing demand for agricultural water in irrigated regions, especially in arid and semi-arid areas, poses a serious problem. Changes in groundwater levels can have adverse effects on surface water flow and the sustainability of water resources and ecosystems. In this study, a two-dimensional unsteady flow model was used to evaluate the demand for agricultural water in the Jiaokou Irrigation District. The results showed that while groundwater in the study area is relatively balanced, there is insufficient supply of irrigation water during summer. Different scenarios were tested, and the one based on the Hanjiang-to-Weihe River Valley Water Diversion Project was found to be the most reasonable and sustainable.
