Irrigation System Management (ISM) poses many issues in terms of social and technical aspects. These can be further elaborated as the issues toward the efficiency of infrastructure, equity of water sharing, environmental integrity and economic acceptability. Water losses and the structural changes of the system caused many issues putting the irrigation system into distress. Hence, this urges the need for sustainable ISM to improve social and technical attributes in ISM. This paper aims to apply the Socio-Technical Systems (STSs) theory for sustainable ISM.

The qualitative expert opinion survey method was selected as the research strategy to approach the research aim. Sixteen industry professionals in the ISM sector were selected through the purposive sampling method to conduct semi-structured interviews to collect data in the Sri Lankan context. Code-based content analysis through a directed approach was used to analyse the data.

Four main categories of strategies were emerged from the research findings as “engineering strategies”, “operational strategies”, “management strategies” and “regulatory strategies” through STS approach for sustainable ISM. The STS framework was developed by combining engineering and operational strategies into the technical subsystem and the management and regulatory strategies into the social subsystem to approach the aim of achieving contemporary system management in irrigation in a sustainable manner.

The research revealed the links between the strategies emerged from various disciplines to minimise the issues in ISM from the perspectives of technical and social subsystems. The study contributes to knowledge by providing a framework for sustainable ISM by applying the socio-technical systems theory by integrating the concepts of sustainability.

The study aims to develop recommendations for optimal Internet of things (IoT) based solutions for a smart precision irrigation automation platform using morphological thinking (MT). The smart irrigation system (SIS) can be applied for green roof and green wall (GRGW) design by studying the relationships and configurations that will be analyzed, listed and synthesized, representing “solutions spaces” and their possibilities.

The research examines studying various cases of SIS; and assessing and analyzing the identified case studies through a decision support system (DSS) considering several factors regarding IoT, plant characteristics, monitoring, irrigation system and schedule, climate, cost and sensors used.

To develop recommendations for optimal IoT-based solutions for a smart precision irrigation automation platform.

The research paper analyzes and proposes a simultaneous solution to two conflicting problems. On the one hand, the paper proposes to apply greening of walls and roofs in hot arid regions, which will achieve greater environmental comfort. However, this is extremely difficult to implement in hot arid regions, since there is an objective problem – a lack of water. At the same time, the paper proposes the most rational approaches to organizing an irrigation system with the lowest water consumption and the highest efficiency for landscaping. Accordingly, this paper focuses on evaluating different types of SIS about the hot-arid climate in Qatar. The study aims to develop recommendations for optimal IoT-based solutions for a smart precision irrigation automation platform, which can be applied for green wall and roof design.

Sustaining the irrigated agriculture, while conserving the natural eco-system, are the two main objectives of sustainable water management (SWM) in irrigation. Achieving both the objectives simultaneously is a complex task in most developing countries. This requires a holistic approach of understanding the issues in irrigation water management (IWM) from social, economic and environmental perspectives. Therefore, this paper aims to analyse the issues towards the SWM of irrigation systems in Sri Lanka to help maintain a stable relationship between the aforementioned two objectives.

Qualitative interview survey was selected as the research strategy to achieve the research aim. 16 semi-structured interviews were conducted with experts in IWM sector to collect data in the Sri Lankan context. Data were analysed using code-based content analysis, based on directed approach.

Findings revealed the issues in SWM in terms of efficiency of irrigation infrastructure; equity of water distribution; environmental integrity and economic acceptability. Most of the issues were related to the inefficiency towards SWM of irrigation systems. Conflicts among water users, especially the people in downstreams aggravated the problem of equity of water sharing. Depletion of groundwater and waterlogging were the major issues towards environmental integrity. Loss of water happened due to the issues in different irrigation infrastructure components hindering economic acceptability.

Theoretical contribution includes an analysis of issues in IWM from a sustainability perspective. Practical implications include an overview of deficiencies in the SWM to generate appropriate strategies to achieve sustainability for decision-makers such as policymakers in the irrigation sector in developing countries similar to Sri Lanka.

The purpose of this paper aims to reduce the manpower, electricity, and water consumption for irrigation.

The IoT-based smart irrigation system designed with various sensors to collect farm field data, and stored all the data in the cloud for scheduling the irrigation.

Difficult to implement on a small farm field with different crops.

Crop type, soil type and environment data should be considered for better saving of water.

Reduces the water consumption, electricity, man power and increase production.

The soil type, crop type and environment data have been added before irrigation. The climate data also included before scheduling. Dynamic changing of irrigation timings based on the climate and sensor data.

This chapter presents the Smart Irrigation system using the Internet of Things (IoT). IoT Technology is a network of physical objects that are connected with sensors, software, etc. This chapter concludes the project based on the agriculture field that automates the irrigation process and on the agriculture field that automates the irrigation process and solves the challenge of water consumption in those areas. We have developed the system using different sensors like (1) Soil Moisture sensor, which measures the moisture present in the soil, (2) Humidity and Temperature Sensor (DHT11), which traces the temperature change. All these sensors are connected to the Node MCU ESP8266 microcontroller, which is also a Wi-Fi module. It uploads the data to the cloud and displays it in the form of readings detected by the Blynk Application. This sensor's reading values control the pump for emergency purposes, such as stopping the pump for irrigation. Thus, this project can automate the irrigation process by analyzing soil moisture and climatic conditions, covering essential aspects like less labor, power consumption, reliability, and cost.

Heavily subsidised irrigation systems have been the government’s measure to improve the farmer’s lives. However, evaluation of the performance of these systems was often overlooked. Thus, this study aims to assess the efficiency of irrigation systems in Davao del Sur, Philippines, according to agricultural, social and economic aspects, namely cropping intensity, functionality and production and monthly average income per hectare, respectively. More than half of the national irrigation schemes exhibited outstanding functionality based on organisation, system and operation and maintenance areas, while almost 75% of the communal schemes have exhibited the same. On the other hand, communal systems have higher cropping intensities (wet – 106% and dry – 116%) than those of the national schemes (wet – 89.8% and dry – 89.1%). Results show that communal systems perform better than those managed by Irrigation Administration. The former have been given the full control over their farm areas, where it is expected that members of the association are able to fully articulate in the decision-making and participate in their activities. Although irrigation managers of the said agency have key roles in the capacity building and management of the irrigation systems, performances of such systems largely depended on how well farmers manage the irrigation association.

This study aims to examine the effect of the Internet on irrigation system adoption. The authors implement the most extensive household survey of irrigation arrangements ever conducted in rural China and also exploit a public program to improve the quality of distance education in rural middle schools, which has led to plausibly exogenous variation in Internet access across rural districts.

The authors present a conceptual framework highlighting the transmission mechanisms whereby Internet access may affect irrigation system selection and identify direct effects through agricultural production and an indirect effect through non-agricultural production. To examine the effect of the Internet on irrigation system adoption, we implement the most extensive household survey of irrigation arrangements ever conducted in rural China. We also exploit a public program to improve the quality of distance education in rural middle schools, which has led to plausibly exogenous variation in Internet access across rural districts.

The authors find evidence to suggest that Internet access can effectively reduce information frictions and searching costs in the non-agricultural labor market, thus increasing rural households' participation in non-farm work. To save more hours from agricultural production, rural households select more labor-saving irrigation systems.

This study’s findings have important implications for the ongoing policy debate over government investment in Internet infrastructure to improve agricultural development in rural and isolated areas.

This study aims to provide a new method for precisely sizing photovoltaic (PV) arrays for standalone, direct pumping PV Water Pumping (PVWP) systems for irrigation purposes.

The method uses historical weather data and considers daily variability in regional temperatures and rainfall, crop evapotranspiration rates and seasonality effects, all within a nonparametric bootstrapping approach to synthetically generate daily rainfall and crop irrigation needs. These needs define the required daily supply of pumped water to achieve a user-specified level of reliability, which provides the input to an intuitive approach for PV array sizing. An economic comparison of the costs for the PVWP versus a comparably powered diesel generator system is provided.

Pumping 22.8646 m³/day of water would meet the pasture crop irrigation needs on a one-acre (4046.78 m²) tract of land in South Florida, with 99.9% reliability. Given the specified assumptions, an 8.4834 m² PV array, having a peak power of 1.1877 (kW), could provide the 1.2347 (kWh/day) of hydraulic energy needed to supply this volume over a total head of 20 meters. The PVWP system is the low-cost option when diesel prices are above $0.90/liter and total installed PV array costs are fixed at $2.00/Watt peak power or total installed PV array costs are below $1.50/Watt peak power and diesel prices are fixed at $0.65/liter.

Because the approach is not dependent on the shapes of the sampling distributions for regional climate factors and can be adapted to consider different types of crops, it is highly portable and applicable for precisely determining array sizes for standalone, direct pumping PVWP systems for irrigating diverse crop types in diverse regions.

Effective irrigation management hinges upon effective collective action among farmers and irrigation managers. The purpose of this study is to examine how the institutional design of irrigation agency affects the incentives and ability of irrigation managers to do a conscientious job and to relate to farmers in managing irrigation, and hence affects irrigation performance.

This study compares the Department of Irrigation (DOI) in Nepal and the Irrigation Associations (IAs) in Taiwan. Based upon extensive fieldwork undertaken in the two countries, this study identifies the opportunities and constraints embedded in the institutional designs of the agencies, and analyzes their effects on the behavior of irrigation managers.

The two irrigation agencies are designed upon very different conceptions of how the provision and production of irrigation can be organized. The DOI is built upon the premises of top‐down control, a reliance on technical knowledge, professional management, and uniform rules and regulations. The IAs, on the other hand, are designed upon the premises of reciprocity among irrigation managers, complementarity between the agency and farmers' efforts, the importance of mobilizing local knowledge and resources, the embeddedness of the agency in local communities, and a problem‐solving orientation.

Irrigation institutions that enable farmers and irrigation managers to cope with the problematics involved in the provision and production of irrigation operation and maintenance (O&M) are better able to nurture and sustain synergistic and productive working relationships.

The findings of this study can inform policy reform in the irrigation sector in specific, and in resource management and development administration in general.

This study provides not only a theoretical perspective for understanding and comparing institutions, but also empirical evidence for understanding how institutions affect irrigation performance.

Sri Lanka, as an island located near the southern tip of India and the Asian Continent and in the core area of the South Asian Monsoon has developed its own unique forms of Hydraulic Civilization. Sri Lanka is covered with a network of thousands of man-made lakes and ponds, known locally as “tanks,” numbering more than 25,000. Some are in the functional mode and others still remaining abandoned type. Many are thousands of years old and almost all show a high degree of sophistication in their construction and design. Sri Lanka's tanks are fascinatingly distributed in the cascades of tanks one below the other conserving water and soil and most effectively, acting as buffers against droughts while giving due consideration to maintaining the ecosystem equilibrium.
