Standards For Landscape Irrigation Systems
Introduction:
The following Standards for Landscape Irrigation Systems replace the previous publication of March 1997. They have been developed by the Irrigation Industry Association of British Columbia to reflect the current minimum Standards for the industry and to provide guidance to its members as a benchmark for their performance. The principles embodied in these Standards apply to all landscape irrigation systems but the special circumstances of some owners or installations may require the development of more customized specifications related to the project. The use of these Standards is intended to encourage efficient and responsible water management and result in irrigation systems that are economical, practical, and sustainable. Owners, designers, and installers of these systems are responsible for the use of a precious and finite resource to maintain healthy and functional landscapes. Accepted industry practice reflects these goals. The Irrigation Industry Association of British Columbia accepts no liability arising from the use of these Standards in contractual relationships between parties to an irrigation project.

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.

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.

A Benefit-cost Analysis Of Treated Wastewater Reuse For Irrigation In Tubas
The West Bank, Palestine suffers from water scarcity due to the high population growth rate, the political situation that dictates the utilization and development of the water resources and the arid and semiarid climate conditions. Reuse of treated wastewater can be a source of water for the
irrigation of agricultural crops and thus this will lessen the stress on the water resources, increase the agricultural productivity and prevent the pollution of
the soil and groundwater. This work investigated the feasibility of reusing treated wastewater for irrigation in the Tubas area. Thereafter, a benefit-cost analysis was carried out to estimate the cost of the reuse of the treated wastewater in Tubas area. The study considered five options for wastewater treatment in Tubas area: construction of a treatment plant for the wastewater originating from the north of Tubas, south of Tubas, north of Tubas and Tayaser village, all of Tubas, and all of Tubas and Tayaser village, respectively. The study analyzed three systems for secondary wastewater treatment: activated sludge (AS), trickling filter (TF) and aerated lagoons (AL).

Soil Water Flow And Irrigated Soil Water Balance In Response To Powder River Basin Coalbed Methane Product Water
In the soil columns experiment, A and B horizon materials from sandy loam, silt loam, and clay loam soils were pre-treated with water having salinity and sodicity typical of PRB CBM water or of Powder River (PR) water currently used for irrigation in the basin. Tension infiltrometer measurements were used to determine infiltration flux, first using pre-treatment water, and subsequently deionized (DI) water, simulating rainwater. Measurements were compared by pre-treatment water, horizon, and soil type. Under pre-treatment water testing, the sandy loam and clay loam soils pre-treated with CBM water exhibited smaller infiltration flux values than when pre-treated with PR water. Only the sandy loam soil showed a greater decrease in infiltration flux with DI water on soils pre-treated with CBM relative to PR water pre-treated soils. There was no difference in infiltration flux decrease with DI water between A and B horizon soils, or between smectite and non-smectite soils.

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.

Soil Hydrology for a Sustainable Land Management
Soil hydrology determines the water–soil–plant interactions in the Earth’s system because porous medium acts as an interface within the atmosphere and lithosphere; regulates main processes such as runoff discharge, aquifer recharge, movement of water, and solutes into the soil; and ultimately the amount of water retained and available for plants growth. Soil hydrology can be strongly affected by land management. Therefore, investigations aimed at assessing the impact of land management changes on soil hydrology are necessary, especially to optimize water resources. This Special Issue collects 12 original contributions addressing the state-of-the-art advances in soil hydrology for sustainable land management.
These contributions cover a wide range of topics including (i) the effects of land use change, (ii) water use efficiency, (iii) erosion risk, (iv) solute transport, and (v) new methods and devices for improved characterization of soil physical and hydraulic properties. They include both field and laboratory experiments as well as modelling studies. Different spatial scales, i.e., from field to regional scales, and a wide range of geographic regions are also covered. The collection of these manuscripts presented in this Special Issue provides a relevant knowledge contribution for effective saving water resources and sustainable land management.

Water and Agriculture: Towards Sustainable Solutions
The main pressures from agriculture are linked to diffuse pollution from nutrients and chemicals, water abstraction and hydromorphological changes. Often several pressures act at the same time, potentially increasing the range of ecological impacts. According to information reported under the WFD, around one third of surface water bodies fail to achieve good status because of one or several of these pressures.
