Special Issue Information

Dear Colleagues,

Water and energy are essential resources to ensure the productivity of agricultural irrigation systems: the former because of its limited availability, the latter because of both the environmental impacts of CO2 emissions and its cost that, in some cases, could threaten the activity of irrigation. It is becoming more critical to use the right amount of water while minimizing energy costs and carbon footprint.

In recent years, there have been many technological advances, whose incorporation into agriculture has enabled us to establish the Agriculture 4.0 framework that can monitor agricultural processes in real time, reducing uncertainties. Furthermore, the new EU guidelines, such as the Green Deal and digitization, pose new challenges for making agriculture more sustainable and resilient to climate change, contributing effectively to climate change mitigation.

This Special Issue welcomes research works about efficient water and energy use in irrigation, mainly including new technologies and approaches such as precision irrigation, sensors, big data, Internet of Things  (IoT), Artificial Intelligence (AI), modelling techniques, renewable energy sources, and unmanned aerial vehicles.

Design strategies to enhance modern irrigation practices, reduce energy consumption, and improve water use efficiency and crop yields are fundamental for sustainability. Concerning Center-Pivot Irrigation Systems, different design procedures aimed at optimizing water use efficiency have been proposed. Recently, following a gradually decreasing sprinkler spacing along the pivot lateral with constant diameter and sprinkler flow rate, a new design method providing a uniform water application rate has been introduced. However, no suggestions were given to design multiple-diameter laterals characterized by different values of the inside pipe diameter. In this paper, first the previous design procedure is briefly summarized. Then, for the dual-diameter center pivot laterals a design procedure is presented, which makes it possible to determine pipe diameters that always provide sprinkler pressure heads within an admitted range. The results showed that for the assigned input parameters, many suitable solutions can be selected. The lateral pressure head distributions were compared to those derived by the common numerical step by step solutions, validating the suggested simplified procedure. An error analysis was performed, showing that the relative error, in pressure heads, RE, was less than 2.3%. If imposing the mean weight diameter, Dm, equal to its minimum value, the optimal pressure head tolerance of the outer lateral, δI, amounting to about 2%, with the RE in pressure heads being less than 0.4%, which makes the suggested procedure very accurate. Several applications were performed, compared, and discussed. Full article
