Supply chain risk model for cement industry based on interpretive structural model driven by FMEA

Purpose: This paper aims to identify, analyze, model the risk elements in the supply chain and further set future trends to evaluate risks in other domains of cement manufacturing industry. Cement is the second most consumed material in the world, has a fast supply chain in the global market. This has driven the authors to study the supply chain risks for this sector. Design/methodology/approach: Through a detailed literature review and interaction with industry experts, 19 risk elements have been identified that may disrupt the supply chain activities. Failure Mode and Effect Analysis (FMEA) is used to prioritize these risk elements based on the risk priority number (RPN). RPN is derived from the severity, occurrence, and detectability of these risk elements in various process functions of the supply chain. 10 risk elements are selected from this analysis that have higher priority number. Further, these elements have been fed to the Interpretive Structural Model (ISM) that derived the contextual interrelationship among these elements. Further MICMAC analysis has been implemented on the risk elements based on their driving and dependency power. Findings: Unpredicted heavy rainfall and energy shortages have been identified as the root causes of other risk elements. Increasing turnaround time in logistics and fleet adjustment during heavy demand, having the highest dependence power, are considered as the most important risk elements in the cement industry supply chain. Originality/value: This is the first study in the domain of supply chain risks which has analyzed and modelled risks for cement industry. This work would provide the decision-makers of cement industry to focus on the specific risk elements for reducing disruptions in the supply chainPeer Reviewe

Relationship between food security, agriculture and the sustainable development goals: a bibliometric analysis

Purpose. Given the urgent need to save the planet, countries are striving to achieve the UN Sustainable Development Goals (SDGs). Agriculture is one of the sectors that contributes to the achievement of these goals on a global scale. As practices in this sector change, direct impacts on soil, air and water are evident, calling into question the sustainability of these practices. Furthermore, food security or food availability is also directly linked to the achievement of the SDGs. With limited research, this study examines the relationship between food security, agriculture, and SDGs. Methodology / approach. This research conducted a bibliometrics analysis from two databases, Web of Science (WoS), with 1450 papers and Scopus 463 documents for 10 years from 2014 to May 2024. Key parameters are identified and ranked, including highly productive authors, countries, disciplines, and institutions. The bibliometric software VOSviewer was used to perform co-word analysis and identify research clusters. Results. The research findings indicate that the United States, followed by India and China, have demonstrated the highest levels of publication activity within the field. The literature predominantly emphasises the SDGs, particularly Zero Hunger, Climate Action, and Life on Land, through the lens of agriculture and food security. The study underscores the leadership of the United States, India, and China in agricultural research, highlighting the critical necessity for concerted collaboration among researchers, policymakers, and practitioners to foster a transformative food system globally. The findings suggest that agriculture is crucial in attaining food security by guaranteeing sustainable food production, combating hunger, and encouraging activities that improve environmental conservation – all critical for long-term food availability –because of SDG 2: Zero Hunger. Originality / scientific novelty. This paper stands out for its originality as, by using bibliometric analysis, the study systematically maps the scientific literature and uncovers nuanced connections between food security, agriculture, and SDGs. Such an analysis has not yet been widely documented. This study contributed to a deeper understanding of the relationships and dynamics shaping global efforts to achieve food security and sustainable agriculture. Practical value / implications. This study offers a new perspective on how these critical areas of food security, agriculture, and SDGs interplay and evolve, providing crucial insights for policymakers, researchers, and practitioners alike. Moreover, the paper contributes to the academic discourse by synthesising trends, identifying gaps, and suggesting future research directions, paving the way for informed decision-making and impactful interventions in global food security and sustainable agriculture efforts

Discovery of an aborted reversal (geomagnetic excursion) in the Late Pleistocene sediments of Pinjor Dun, NW Himalaya

We report here the occurrence of an aborted reversal (geomagnetic excursion) in the Late Pleistocene sediments of Pinjor Dun near Chandigarh, NW Himalaya. The event discovered at ~697.5 cm level from the base of Kiratpur section corresponds to the OSL date of 40±5 Ka coinciding with the Laschamp excursion and palaeointensity minima elsewhere. The Pinjor Dun sediments are deposited at a high rate of sedimentation that enables quite enlarged records of remanent geomagnetic field, hence suitable for further high resolution study of the excursion (under progress) to extend its utility as a stratigraphic marker in the Quaternary sediments at the foothills of the Himalaya

A Study of Air Pollution load assessment around opencast coal project in India

Opencast mining technology results in the release of a huge amount of air borne dust. The air borne dust peculiarly below 100 micron in size, are environmentally nuisance and cause health hazards. Total suspended particulate matter (TSPM) and respiratory particulate mater (PM10) are the major pollutants in the air environment of opencast coal mines. Therefore, dust generation, its dispersion, and pollution load assessment have been found to be major concer4ns in air quality modeling of opencast coal mines. The present paper focuses on the quantification of sourcewise emission inventory for different point, area and line sources considering the background dust concentration at one of opencast coal project (OCP), nakmely Hindustan Lalpet of Western Coalfields Limited (WCL). The 24 hr average concentrations of TSPM and PM10 were monitored at three monitoring stations during winter season. On an average the PM10 concentration in the ambient air constituted 17.00 to 60.3% of TSPM concentration. TSPM concentration ranged from 313.11 to 565.57 µg/m3 and 79.48 to 270.61 µg/m3

Metal pollutants in Indian continental coastal marine sediment along a 3,700 km transect: An Electron Paramagnetic Resonance spectroscopic study

We report the analysis and geographical distribution of anthropogenically impacted marine surficial sediments along a 3700 km transect around the continental shelf of India. Sediments have been studied using a mixed analytical approach; high sensitivity electron paramagnetic resonance (EPR), chemical analysis and environmental magnetism. Indian coastal marine deposits are heavily influenced bymonsoon rains flushing sediment of geological and anthropogenic origin out of the subcontinental river systems. That is, climatic, hydro-, geo- and anthropogenic spheres couple strongly to determine the nature of Indian coastal sediments. Enrichment of Ni, Cu and Cr is observed in shelf sediments along both east and west coasts associated with industrialised activities in major urban areas. In the Gulf of Cambay and the Krishna and Visakhapatnam deltaic regions, levels of Ni and Cr pollutants (≥80 and ≥120 ppmrespectively) are observed, sufficient to cause at least mediumadverse biological effects in the marine ecosystem. In these areas sediment EPR spectra differ in characteristic from those of less impacted ones. Modelling enables deconvolution of EPR spectra. In conjunction with environmental magnetism techniques, EPR has been used to characterise species composition in coastal depositional environments. Paramagnetic species can be identified and their relative concentrations determined. EPR g-values provide information about the chemical and magnetic environment of metals. We observe g-values of up to 5.5 and large g-shifts indicative of the presences of a number of para and ferrimagnetic impurities in the sediments. EPR has enabled the characterisation of species composition in coastal depositional environments, yielding marine sediment environmental ‘fingerprints’. The approach demonstrates the potential of EPR spectroscopy in the mapping and evaluation of the concentration and chemical speciation in paramagnetic metals in sediments from marine shelf environments and their potential for source apportionment and environmental impact assessment
