Examining the Challenges of Implementing Artificial Intelligence in the Water Supply Sector: A Case Study

Challenges in the water supply sector have hindered the advanced implementation of artificial intelligence (AI) compared to other sectors. These challenges have not been sufficiently examined in the existing literature. An empirical study was conducted within a public utilities organization in the United Arab Emirates (UAE) to address this gap. An integrated approach combining interpretive structural modeling (ISM) and fuzzy cross-impact matrix multiplication applied to classification (MICMAC) analysis was utilized to identify the critical challenges and to model and analyze the relationships among them. The ISM model provides significant advantages by enabling decision-makers to visualize complex interactions, supporting the development of an effective AI implementation strategy. The strategy should prioritize four critical challenges: the lack of technical skills and knowledge, the limited availability of ready-to-use AI solutions, inadequate water infrastructure, and concerns regarding privacy and data security. These challenges were identified based on their positioning at the lowest level of the ISM model and their classification as independent in the fuzzy MICMAC analysis. Addressing these four challenges will help to mitigate the remaining six. The study’s findings and implications are expected to offer valuable guidance for decision-makers in implementing AI technologies within water supply organizations, both in the UAE and in countries with similar environments.

Digital data demand and renewable energy limits: Forecasting the impacts on global electricity supply and sustainability

This study critically evaluates whether the current and projected generation of renewable energy can meet the escalating global demand for electricity from digital data growth. Our modelling forecasts reveal a concerning trend: despite the expansion in renewable energy capacities, they are likely insufficient to satisfy the burgeoning electricity needs of the digital data sector. More alarmingly, there is a real risk that the demand for digital data could soon exceed feasible electricity production capabilities. This paper underscores the urgent necessity for a data-centric sustainability approach across all supply chains, sectors, industries, and nations. Such measures are crucial to increase efficiency, cut energy usage, and transition towards a decarbonized digital ecosystem, thereby supporting the global pursuit of a sustainable, net-zero future. This research highlights a critical junction in energy policy and digital infrastructure planning, urging immediate action to reconcile digital advancement with ecological sustainability.

A Novel Application of B.EL.D™ Technology: Biosensor-Based Detection of Salmonella spp. in Food

The prevalence of foodborne diseases is continuously increasing, causing numerous hospitalizations and deaths, as well as money loss in the agri-food sector and food supply chain worldwide. The standard analyses currently used for bacteria detection have significant limitations with the most important being their long procedural time that can be crucial for foodborne outbreaks. In this study, a biosensor system able to perform robust and accurate detection of Salmonella spp. in meat products was developed. To achieve this, a portable device developed by EMBIO Diagnostics called B.EL.DTM (Bio Electric Diagnostics) and cell-based biosensor technology (BERA) were used. Results indicated that the new method could detect the pathogen within 24 h after a 3-min analysis and discriminate samples with and without Salmonella with high accuracy. Achieving an accuracy of 86.1% and a detection limit (LOD) of 1 log CFU g−1, this innovative technology enables rapid and sensitive identification of Salmonella spp. in meat and meat products, making it an excellent tool for pathogen screening.

Performance and regional applicability analysis of a building low-carbon heating system based on PV/T-GSHP

Solar energy and geothermal energy, as conveniently usable clean and renewable energy sources for human society, have been widely developed and utilized in recent years. Photovoltaic/thermal (PV/T) and ground source heat pump (GSHP) technologies, as efficient methods for utilizing these two types of clean energy, have attracted significant attention and extensive research. This study focuses on an integrated heating system of PV/T and GSHP, and employs a multi-criteria optimization method based on game theory principles to optimize the basic parameters of the low-carbon heating system for optimal system design. By evaluating the performance of the system in terms of energy efficiency, economy, environment, and independence in 34 major regions, the regional applicability of the system is assessed. Macao, Tibet, Qinghai, and Ningxia are the regions with the highest scores of 100、91.49、80.95 and 74.39, respectively. In contrast, regions with low scores such as Guizhou, Taiwan, Chongqing, Sichuan, and Hunan are primarily influenced by economic factors and annual irradiation levels. The proposed low-carbon heating system performs well in more than 50% of the areas. Considering global annual total radiation and average annual temperature, as well as the heating demands of different regions, the system can achieve a supply of clean energy ranging from 37% to 112%. The research and application of the PV/T-GSHP system are of great significance for achieving carbon neutrality in the building energy supply sector.

Environmental quality in Africa and infrastructure development: The mediating impact of the knowledge economy

AbstractThe study investigates the impact of infrastructure development on environmental quality and the mediating impact of the knowledge economy in 48 African economies from 2000 to 2020. The Generalized Method of Moment is adopted to control for error term‐related problems and potential endogeneity through an instrumentation process. The following findings are established: First, Infrastructure development enhances environmental sustainability in Africa, through the reduction of greenhouse gasses. Second, it contributes to reducing CO2 emissions in liquid, solid and gaseous states of fuel consumption. These results hold after considering the infrastructure development indicators of the African Development Bank. Third, the findings further reveal that the transport, energy, water supply, and technology sectors all contribute to enhancing environmental quality. Fourth, taking into account differences in factor endowment, the findings indicate that infrastructure development helps reduce CO2 emissions in both lowly and highly endowed African countries, except for electricity and water supply in the lowly endowed economies, indicating that the development in these sectors needed to be speeded‐up to enhance environmental quality in these countries. Fifth, the findings indicate that the knowledge economy mediates with infrastructure development to promote environmental quality through the reduction CO2 emissions. The findings recommend policymakers promote infrastructure development for environmental efficiency in Africa. This is particularly enhanced through the mediation impact of the knowledge economy.

Developing and maintaining a policy-focussed, comprehensive, energy systems model in a developing country context: The case of SATIM in South Africa

South Africa faces a myriad of energy-related challenges, including severe constraints in electricity supply, a rising cost of electricity to consumers, high levels of energy poverty, and a reliance on coal in both energy supply and demand sectors. These challenges exist in a context of significant development imperatives and commitments to decarbonise. This paper presents the South African TIMES model (SATIM), a comprehensive energy systems model developed and maintained over two decades, which has proved useful in informing energy and climate policy in South Africa. We explore how SATIM has been adapted to overcome data limitations and address unique and complex policy, development and broader socio-economic challenges faced by developing countries. The model's evolution, structure, and applications are discussed, highlighting its role in providing evidence-based insights for critical policy decisions. We argue that SATIM's long-term development, flexibility, and integration with other models offer valuable lessons for energy systems modelling in developing country contexts.

Role of supply chain digitalization and global supply chain in decarbonization of natural resources sector supply chain

Environmental management and decarbonization are becoming increasingly critical as industries seek sustainable development paths that align with global climate targets. As businesses aim to reduce their carbon footprint, integrating effective environmental strategies with technological advancements is essential. This necessitates a clear understanding of digital technologies and environmental policies to drive decarbonization efforts. In this context, this study explores the role of digitalization in reducing carbon emissions in the natural resources sector supply chain. Furthermore, it examines the role of supply chain mapping as a mediator in the relationship between supply chain digitalization and supply chain decarbonization efforts, providing a novel perspective on how technology can intersect to foster environmental sustainability. This research targets the metal sector supply chain, a significant contributor to global carbon emissions. The data for the study was gathered through a questionnaire administered to 246 employees from various levels of the metal industry in China. We employed Covariance-based Structural Equation Modelling (CB-SEM) using AMOs for analysis. Our results show that level digitalization of supply chain processes in the metal sector has a profound and direct impact on its supply chain decarbonization. Digital technologies facilitate more efficient resource use, improved energy efficiency, and the adoption of cleaner production methods. Importantly, the study identifies supply chain mapping as a crucial mechanism through which digitalization exerts its positive influence on decarbonization. Through detailed mapping, organizations can gain visibility over their entire supply chain, identifying carbon hotspots and opportunities for improvement that digital solutions can address. The novelty of this study lies in its systematic exploration of how supply chain mapping serves not just as a tool for transparency and efficiency but as a strategic facilitator of the beneficial impacts of digitalization on decarbonization.

Digital Transformation in the Health Product Supply Chain: A Framework for Analysis

ABSTRACT Well-functioning supply chains for medicines and other health products are vital for a health system’s goals of ensuring access, quality, and efficiency. However, in several countries the performance of government-run supply chains for health products remains subpar. The widespread adoption of digital technology presents new opportunities for enhancing the performance of the health product supply chain. This paper aims to provide a practical and systematic analysis of digital initiatives within health product supply chains. It provides examples of successful digital interventions in each of the Enable, Plan, Source, and Deliver categories of the Supply Chain Operations Reference model. The examples provide clear evidence that the use of digital technology in the health supply chain can improve access and affordability; in some instances, use of digital technology can lead to faster health product adoption and alter the overall architecture of decision making. While many digital interventions in the public sector supply chain target the collection of data and its analysis and use for reporting, the long-term effectiveness of digital solutions hinges on their ability to enhance the agency of supply chain actors. A thorough and systematic inquiry about the logic model of how a particular digital solution enhances agency and improves accountability is essential at the outset. In developing roadmaps to prioritize and sequence digital solutions in health supply chains, governments should start by asking where lack of information is the primary constraint impeding supply chain performance.

Book Review: Dariusz Grala, "The Security of Military Supply Chains" [“Bezpieczeństwo wojskowych łańcuchów dostaw”], Academy of War Studies Publishing House, Warsaw 2024, ISBN 978-83-8263-503-4, pp. 326.

A new monograph titled "The Security of Military Supply Chains" has emerged in the publishing market, released in 2024 by the Academy of War Studies Publishing House (ISBN 978-83-8263-503-4). This publication spans 326 pages and represents a significant contribution to Polish scientific literature, as the subject matter has not been analysed in such a comprehensive manner until now. The Author of the book is Dariusz Grala, a Colonel in the Polish Army, a Doctor of Engineering, and the current Dean of the Faculty of Management and Command at the Academy of War Studies. The monograph introduces the reader to an extensive, erudite discourse at the intersection of political science research, security studies, and management and quality. The Author meticulously and logically discusses areas related to the security of military supply chains, which have previously been underexplored in the literature. The term "security" is understood here in various contexts, encompassing both states and processes that influence military supply chains. The Author highlights their role as a set of cooperating structures aimed at delivering goods essential for the execution of military training operations, operational activities, and combat missions. The literature often encounters the term "defence sector supply chains"; however, in the military context, the perspective on the functioning of these supply chains has a broader and often sensitive significance. This "sensitive" nature of the security of military supply chains —understood from the intentions expressed in the Introduction — has become the subject of the Author's research, which integrates theories and practices from military logistics and supply chain management. The considerations focus on the processes occurring within these chains under various conditions. This approach is particularly important in the realm of security and defence, as civil supply chain publications often overlook, assuming it to be self-evident, the specific security considerations related to military needs. This publication, in a sense, bridges these two worlds.

Evolution of performance in the water and sewage sector in Brazil: a robust directional Benefit-of-the-Doubt assessment of municipalities from Santa Catarina state

AbstractThe water supply and sewage sector (WSS) is essential for promoting health and providing the population with drinking water and the adequate disposal of effluents. Assessing the evolution of performance in WSS allows for highlighting the best and worst results achieved, identifying benchmarks, and pinpointing sources of improvement for water services. Brazil has a large population and immense freshwater reserves that are unevenly distributed throughout the territory. This situation emanates a challenge that requires the efficient management of water resources. This study develops a composite indicator framework based on the robust Benefit-of-the-Doubt (BoD) approach to estimate the performance of municipalities of the Brazilian State of Santa Catarina from 2009 to 2021, considering financial, operational, and quality dimensions associated with the provision of WSS services. Subsequently, the Global Malmquist Index (GMI) is applied to assess the performance evolution of the municipalities over time. The BoD results enable the quantification of the relative contribution of each sub-indicator to the performance score, allowing the assessment of the strengths and weaknesses of each municipality. The GMI results show an average performance loss of 3.3% in Santa Catarina state and considerable variability among municipalities, with scores ranging from losses of 54.2% to gains of 109.3% in the period analysed.

Hierarchy and mobility of Latin America and Caribbean container ports

Research on port hierarchies within a maritime region is crucial for comprehending the dynamics of seaborne trade and the broader trends within the maritime sector and related supply chains. This study investigates the evolution of the Latin America and the Caribbean (LAC) container ports and regional sub-systems from 2000 to 2022, analyzing traffic dynamics, shifts in port throughput rankings, and market concentration trends in and among the different coastal regions. Conceptually, this analysis benefits from the notion of evolutionary phases, revealing the stages of a port system's development. Methodologically, 49 LAC ports of international interest are categorized into different coastal regions and tiers based on throughput sizes. Various metrics, including the Gini coefficient, Lorenz curve, Herfindahl-Hirschman Index (HHI), and Kendall Tau (τ), assess port hierarchy and related mobility since 2000. The observed shifts in the hierarchy and market structures, coupled with the fluctuating positions of critical ports, underscore the transition that LAC container ports dynamics experienced in the 21st century. Following a particularly dynamic and volatile evolution observed in the 2000s, the financial crisis of 2008/09 was a critical juncture leading to the transition of the LAC port dynamics from the ‘emerging’ to the ‘maturity’ phase. On the contrary, the pandemic (2019) has not affected the pre-existing hierarchy or the moderate market concentration that was already in progress. The LAC region comprises port sub-systems (coastal ranges) subjected to different tendencies towards (de)concentration, yet mobility in port rankings within each sub-system decreases. The study also reveals the coexistence of this transition with a structural transformation of port governance structures, i.e., granting of concessions of operations to third parties. In 20 of these ports and the above-average mobility of ports are operated by Global Terminal Operators (GTOs), and calls for further research on the (non) causality of these phenomena.

Potensi dan Peluang Akomodasi Alternatif Glamour Camping (Glamping) di Kawasan Destinasi Pariwisata Sembalun Kabupaten Lombok Timur

The aim of the research carried out was to determine the potential and opportunities for the availability of alternative Glamping accommodation in the Sembalun tourism destination area, East Lombok district, as well as to determine the calculation of Location Quotient (LQ), Specialization Index, Shift Share and Net Shift (PB) in analyzing the potential and opportunities for provision. alternative accommodation. The research methodology used in this research is a type of descriptive quantitative research based on the calculation of the Specialization Index, Location Quotient (LQ), and Shift Share. With a rational-comprehensive approach. Types and sources of data in this research, primary and secondary data, with data collection techniques in literature and direct observation or observations. The results of this research show that the specialization index calculation for 17 (seventeen) sectors based on current prices obtained values ​​of 0.31; 0.30 and 0.26. Meanwhile, based on constant prices, the IS value obtained for 3 (three) years was 0 .62; 0.54; 0.46, the value of the specialization index is close to one. For the combined calculation of LQ and Net Shift, it is known that the accommodation, food and drink provision sector have a value of LQ > 1, and PB > 1, which means that the agricultural sector in a broad sense is based on current and constant prices. for 3 years has a stable LQ value which means the potential and opportunities to build and develop accommodation in tourism destinations, are still quite large.

Economic and supply chain impacts from energy price shocks in Southeast Asia

Following the war in Ukraine, it became evident that substantial energy price increases had complex impacts on the economic systems and supply chains throughout the Southeast Asian region. In this article, we employ a global applied general equilibrium model (GTAP-E-PowerS) to examine how ongoing energy price increases might affect sectors, economies and emissions levels of the region. We additionally investigate how technological development including energy efficiency gains, utilisation of capital and how output augmenting technologies may help mitigate costs. Our findings indicate demand for renewable energy by private and industrial sectors increase substantially as a substitute for traditional fossil fuels, but are not adequate to compensate for losses. Agriculture and food sectors are not significantly affected, suggesting less hazards to food security as they are not energy-intensive. Manufacturing, transport and electricity generation sectors, which are energy-intensive, are materially adversely affected. More interestingly, however, is the primary energy supply sectors, viz. oil and gas extraction, and petroleum product manufacturing sectors, whose output declines by 20–70 % across countries. Real GDP also declines substantially, by 1.0–3.8 % in the Philippines, Singapore, Vietnam, Indonesia, Malaysia and Thailand. Conversely, total emissions decline by 6–22 % across countries. Of the options considered, investment in improving utilisation of capital resources is found to be the most effective against energy price shocks.

Are regional groundwater models suitable for simulating wetlands, rivers and intermittence? The example of the French AquiFR platform

Predicting and managing water resources at regional scale under different climate and socio-economic scenarios is crucial to support drinking water supply and other sectors. At the same time, protecting rivers and wetlands from pollutions and droughts is essential and must include groundwater given its contribution to surface water. Yet, assessing temporal and spatial variability of groundwater contributions to surface water is constrained due to limited observations. This study aims to quantify the spatio-temporal distribution of groundwater discharge (hereafter called “GW discharge”) zones, i.e. the groundwater flow to rivers and wetlands, estimated by calibrated regional groundwater flow models (French AquiFR platform). We compare simulation results with two types of surface observations: (i) the spatial distribution of surface water (BD TOPO, RAMSAR and Natura 2000 database) and (ii) an innovative datasets, the river intermittence observed in headwaters (ONDE network). Results show that simulated GW discharge zones are consistent with the observed location of rivers and wetlands. Time variations in GW discharge are well correlated with the intermittence observed at 396 of the 515 selected stations. Of these, groundwater model continues to feed surface water upstream of the station for ∼75 % of observed river drying up events, which may be consistent with a small alluvial flow. The groundwater withdrawals are shown to have a strong impact on the GW discharge and thus on the river intermittence.

Using an interactive simulation tool of national energy and climate policy planning to explore environmental policy options from the perspectives of different interest groups

AbstractTo reach the Paris Agreement goals, European governments have defined national contributions to the EU binding climate goals and have developed national climate and energy plans for 2021–2030 (NECPs). NECPs are detailed strategies in which governments can flexibly emphasize specific sectors, technologies and national energy policy choices. Every country has built its own energy modelling capacity for forecasting purposes. In most countries, this national modelling relies on optimization tools such as Markal or TIMES. For Latvia's energy sector, a system dynamics (SD) model was built to complement the TIMES model. The SD model deals with an integrated energy system, including the primary energy supply and transformation sector; energy distribution and storage system; and energy demand sectors (residential, tertiary, public, industry and transportation). Sectoral policies are presented in the Stella Architect interface. This study demonstrates how the interactive simulation tool was used in the Environmental Engineering Master level course ‘Environmental Policy and Economics’ as an experiential learning approach. The student assignment involved applying this tool to develop and analyse the energy transition policy package for one of four ideological interest groups: deep greens, bright greens, light greens and greys. Students had to assume a role and adopt its perspective by applying their border‐crossing competence and reflecting on selected policy mixes for that ideology. Various transition pathways, based on different ideologies, illustrate the possibilities for application. Results show that students were successful in fulfilling the assignment.

Adoption of Biosecurity Practices among Poultry Farmers in Punjab, Pakistan

Strengthening biosecurity on poultry farms is crucial to mitigate the risk of infectious diseases like avian influenza, which can have far-reaching economic and public health implications. The poultry industry's resilience depends on robust biosecurity practices as a vital component of the country's agricultural sector and food supply. This study was conducted in District Rawalpindi of Punjab province, where 1715 poultry farms were identified. The study was mainly focused on 315 poultry farms selected out of 1715 using the proportionate sampling technique. Managers of these selected 315 farms were interviewed using a structured interview schedule. Collected data were analyzed using Statistical Package for Social Sciences (SPSS). The results revealed a varying level of awareness among different type of poultry keepers. Farmers demonstrated high awareness of vaccination protocols (98.41% and 98.42%), their knowledge of other essential measures, such as fumigation, disinfection, and nutritional supplements, was significantly lower (53.33% to 69.84%). However, awareness and adoption of biosecurity measures were higher among environmentally controlled poultry farms. This study recommends an awareness campaign for poultry farmers using a collaborative approach among veterinary services providers, academia, and research organizations.

Should end-users take their clothes off inside on a cold winter's day? Sustainability pressures on district heating professionals in Denmark

This research explores how district heating (DH) sector professionals /employees experience the low-carbon energy transitions-related change processes in the Danish heat supply sector. Enquiry draws upon mixed data collected among DH employees from 148 utilities. Geels’ triple embeddedness framework conceptualizes the connections between regime-level actor experiences of niche- and landscape-level pressures, sustainability imperatives, and the associated change processes. This neo-institutionalist perspective finds that the historically stable DH regime-level institutions are being destabilised. It also reveals the tensions and change inertia associated with, for example, sunk costs, infrastructural path dependencies, and professional culture. For the DH professionals, and regime-level actors, these destabilization processes challenge what were previously core regime-level professional practices, skills and taken-for-granted standards for a job well done. Indeed, professional identity and pride may be at stake. Paradoxically, the identified DH sector norms for stable, affordable, and invisible heat supply service provision may not necessarily motivate DH end-users /customers towards more sustainable heat-use behaviours: DH end-users in Denmark have come to expect these DH community heat supply provision as taken-for-granted societal goods, and the topics of space heating and thermal comfort are increasingly dissociated from consumption-related debates within public, and political realms. This DH case study shows how landscape, regime, and actor-level socio-technical trajectories interact, and it exemplifies actor-structure relationships in situations of regime stress. Perhaps it proves an exemplary case for exploring the lock-in mechanisms, inertia, restraints, and potentials of change-processes within also other societal domains and institutional realms.

Risks of sanitation and water supply in Pontianak City poorer areas settlements

Abstract The availability of sufficient and safe drinking water is one of the criteria for a settlement to be declared as a poorer area. Areas declared as poorer areas by the city government have water supply problems that require intervention. The Sanitation Risk Index is calculated using a questionnaire on households regarding sanitation conditions and water supply. This research examines the relationship between the Sanitation Risk Index and its effect on water use, as well as the strategies implemented to reduce sanitation risks in water supply in poorer areas in Pontianak City, West Kalimantan. The city of Pontianak is located downstream of Kapuas River. Many settlements grow along riverbanks and require clean water and adequate sanitation facilities. This study began with an assessment of sanitation conditions and clean water supply with a sanitation risk assessment using a questionnaire in poorer areas. The results of the questionnaire led to calculation of the Sanitation Risk Index (IRS). Descriptive and statistical analyses show the relationship between IRS and water supply. In obtaining the water supply strategy carried out here, it was found that more than 50% of the population uses refillable water for drinking; however, rainwater and river water are still used by poorer area settlements for daily activities. The sanitation risk index was 350, indicating the influence of sanitation risk on the quality and supply of water in Pontianak City poorer area settlements. There are urgent problems that must be resolved in the clean water supply sector in the studied poorer areas.
