“…Such systems have proven to have decreased the amount of water used, provided a uniform water distribution and have decrease the amount of fertilizer needed. This correlates directly with the reduction of operational costs on the long run while covering gradually for the capital costs initially invested [17][18].…”

Water Sap flow and Soil Moisture Measurements for an Automatic Irrigation Control System

et al. 2022

A sound water management requires accurate field data inquiry that can eventually allow for a proper control of the field’s irrigation. This work pro-poses an automatic irrigation control system that aims at optimizing the quantity of water needed for plants’ growth. The system consists of three key blocks: first, the continuous inquiry of the physical characteristics of the plant; second, the control unit to decide upon the actions to launch by the actuation unit; and third the actuation unit that sets parameters for pumps and valves. Conventional smart irrigation control systems use soil moister sensors which neglect the plant’s physiology as a monitoring factor, so this paper suggests the use of a sap flow sensor that accurately evaluates the plant’s condition; hence, decide upon the proper water distribution, illustrated with preliminary experimental results.

“…Previous studies have investigated the potential for IoT to reduce environmental impacts in the use-phase of products (e.g., [20,21]). In this study, we add to this by showing that IoT can also bring significant impact reductions in the production phase since it can enable both product lifetime extension and increased product recovery.…”

“…Moreover, they noted that the use-phase impact reduction depended strongly on the ability of the 'smart system' to steer user behavior in a more sustainable direction, mainly to reduce food waste. Yuli et al [21] studied the net GWP reduction from an IoT-enabled irrigation system compared to a conventional irrigation system and concluded that the savings outweighed the impacts. The savings were estimated by the potential for the IoT solution to reduce water and fertilizer consumption in the irrigation system's use phase, while added impacts from the IoT solution itself (sensors, control unit, and gateway) were analyzed cradle-to-grave.…”

Quantifying the Net Environmental Impact of Using IoT to Support Circular Strategies—The Case of Heavy-Duty Truck Tires in Sweden

The idea of leveraging the Internet of Things (IoT) to support strategies in line with the circular economy (CE) has been gaining traction in literature. However, previous work has predominantly focused on the opportunities that these technologies can bring, and few studies have critically assessed the environmental viability of the proposed strategies. In this study, we assess the net environmental impact of IoT-enabled circular strategies in the specific case of truck tires in the Swedish context, in order to gain insight into when and how it makes environmental sense to embed IoT hardware into products to support circular strategies. We quantify (1) the potential environmental savings in the different life cycle phases made possible through access to sensor data, and (2) the environmental impact from the added technology needed to provide and process the data. Life cycle assessment (LCA) is used to evaluate the difference in impact between the current state and an ‘IoT scenario’. We find that the IoT scenario gives a 4% lower weighted life cycle impact than the current state. Through sensitivity analysis, we show that the conclusions are sensitive to assumptions made about the expected benefits of adding IoT, which depend on the technological context as well as the current and IoT-induced behavior of stakeholders along the product life cycle. The results are also sensitive to assumptions about the environmental impact of the IoT hardware components, implying that design decisions at this level can be important for ensuring a net environmental impact reduction from IoT-enabled circular strategies.

“…For many other assessments network infrastructure is not included at the point of intervention and is thus not included in the analysis. For example, Yuli et al (2019) provide a detailed description of the communication devices involved in a precision irrigation control system including sensors and controllers installed in the field, a router housed nearby, and the online systems that include data storage in the 'cloud' and a user interface and store. These online systems are, however, not included in their detailed LCA.…”

Digitally-enabled technologies are increasingly cyber-physical systems (CPS). They are networked in nature and made up of geographically dispersed components that manage and control data received from humans, equipment, and the environment. Researchers evaluating such technologies are thus challenged to include CPS subsystems and dynamics that might not be obvious components of a product system. Although analysts might assume CPS have negligible or purely beneficial impact on environmental outcomes, such assumptions require justification. As the physical environmental impacts of digital processes (e.g., cryptocurrency mining) gain attention, the need for explicit attention to CPS in environmental assessment becomes more salient. This review investigates how the peer-reviewed environmental assessment literature treats environmental implications of CPS, with a focus on journal articles published in English between 2010-2020. We identify nine CPS subsystems and dynamics addressed in this literature: energy system, digital equipment, non-digital equipment, automation & management, network infrastructure, direct costs, social & health effects, feedbacks, and cybersecurity. Based on these categories, we develop a “cyber-consciousness score” reflecting the extent to which the 115 studies that met our evaluation criteria address CPS, then summarize analytical methods and modeling techniques drawn from reviewed literature to facilitate routine inclusion of CPS in environmental assessment. We find that, given challenges in establishing system boundaries, limited standardization of how to evaluate CPS dynamics, and failure to recognize the role of CPS in a product system under evaluation, the extant environmental assessment literature in peer-reviewed journals largely ignores CPS subsystems and dynamics when evaluating digital or digitally-enabled technologies.
