Modelling and Management of Irrigation System
Irrigation is becoming an activity of precision, where combining information collected from various sources is necessary to optimally manage resources. New management strategies, such as big data techniques, sensors, artificial intelligence, unmanned aerial vehicles (UAV), and new technologies in general, are becoming more relevant every day. As such, modeling techniques, both at the water distribution network and the farm levels, will be essential to gather information from various sources and offer useful recommendations for decision-making processes. In this book, 10 high quality papers were selected that cover a wide range of issues that are relevant to the different aspects related to irrigation management: water source and distribution network, plot irrigation systems, and crop water management.

Sustainable Use of Soils and Water: The Role of Environmental Land Use Conflicts
This book on the sustainable use of soils and water addressed a variety of issues related to the utopian desire for environmental sustainability and the deviations from this scene observed in the real world. Competing interests for land are frequently a factor in land degradation, especially where the adopted land uses do not conform with the land capability (the natural use of soil). The concerns of researchers about these matters are presented in the articles comprising this Special Issue book. Various approaches were used to assess the (im)balance between economic profit and environmental conservation in various regions, in addition to potential routes to bring landscapes back to a sustainable status being disclosed.

Optimizing Plant Water Use Efficiency for a Sustainable Environment
The rising shortage of water resources in crop-producing regions worldwide and the need for irrigation optimisation call for sustainable water savings. The allocation of irrigation water will be an ever-increasing source of pressure because of vast agricultural demands under changing climatic conditions. Consequently, irrigation has to be closely linked with water-use efficiency with the aim of boosting productivity and improving food quality, singularly in those regions where problems of water shortages or collection and delivery are widespread. The present Special Issue (SI) showcases 19 original contributions, addressing water-use efficiency in the context of sustainable irrigation management to meet water scarcity conditions. These papers cover a wide range of subjects including (i) interaction mineral nutrition and irrigation in horticultural crops, (ii) sustainable irrigation in woody fruit crops, (iii) medicinal plants, (iv) industrial crops, and (v) other topics devoted to remote sensing techniques and crop water requirements, genotypes for drought tolerance, and agricultural management.

Agroecological Approaches for Soil Health and Water Management
In the last century, innovations in agricultural technologies centered on maximizing food production to feed the growing population have contributed to significant changes in agroecosystem processes, including carbon, nutrients, and water cycling. There are growing concerns regarding soil fertility depletion, soil carbon loss, greenhouse gas emissions, irrigational water scarcity, and water pollution, affecting soil health, agricultural productivity, systems sustainability, and environmental quality. Soils provide the foundation for food production, soil water and nutrient cycling, and soil biological activities. Therefore, an improved understanding of biochemical pathways of soil organic matter and nutrient cycling, microbial community involved in regulating soil health, and soil processes associated with water flow and retention in soil profile helps design better agricultural systems and ultimately support plant growth and productivity. This book, Agroecological Approaches in Soil and Water Management, presents a collection of original research and review papers studying physical, chemical, and biological processes in soils and discusses multiple ecosystem services, including carbon sequestration, nutrients and water cycling, greenhouse gas emissions, and agro-environmental sustainability.

Irrigation Engineering
Purpose of Irrigation
Some of the main purposes of irrigation are enlisted below:
1. To supply essential moisture for plant growth
2. Transportation of fertilizers (Fertigation)
3. To leach or dilute salts in the soil
4. To help in field preparation, dust control, etc.
5. Other benefits of irrigation include cooling the soil and atmosphere to create a more favorable environment for crop growth and frost control.

Safe Use of Wastewater in Agriculture Good Practice Examples
Abstract
Managed aquifer recharge (MAR) systems such as riverbank iltration and soil-aquifer treatment all involve the use of natural subsurface systems to improve the quality of recharged water (i.e., surface water, storm water, reclaimed water) before reuse (e.g. planned potable reuse). During MAR, water is either iniltrated via basins, subsurface injected or abstracted from wells adjacent to rivers. MAR systems represent an attractive option for augmenting and improving groundwater quality as well as for environmental management purposes. However, reuse systems designed for applications that involve human contact should include redundant barriers for pathogens that cause waterborne diseases. This case covers key aspects of a case study on virus removal at three full-scale MAR systems located in different regions of the United States (Arizona, Colorado, and California). MAR projects may be economically viable for developing countries; however, sustainable management is relevant to successfully maintain the attributes necessary for potable and non-potable water reuse.
