    Need for rating system for assessing sustainability of built environment during construction stage
    (2023-06) Dubey, MK; Raj, V; Kumar, M; Garg, V
    Sustainability in construction has gained attention in recent years as the construction industry adversely impacts the environment and green construction has been emphasized. Various rating systems have been developed by various organizations across the world like LEED, USA; CASBEE), Japan; BREEMA, UK; GBCSL, Sri Lanka, IGBC, India; etc. to certify construction projects under the green projects category, based on parameters majorly considering three factors environmental, societal & economic impact during the entire span of a project from inception stage to demolition stage. In these sustainability assessment rating systems, the parameters relevant to the construction phase have not been emphasized except for a few factors which have been considered under pre‐requisite. Though the construction phase has a comparatively shorter duration, it adversely impacts sustainability if considered collectively. So, a holistic approach is needed for sustainability assessment which shall include construction stage‐based sustainability parameters too. In this paper, with a questionnaire survey & interaction with experts, the need for construction‐based sustainability parameters has been discussed for making a holistic sustainability assessment rating system. The survey & interaction data were analyzed with an analytical hierarchical process (AHP) to understand the need for the additional parameter during the construction stage of the project.

    Recent advances in nanotechnology for the improvement of conventional agricultural systems: A review
    (2023-05) Yadav, N; Garg, V; Chhillar, A; Rana, J
    Agriculture provides food and raw materials for the construction, energy, textile and pharmaceutical industries. Recently, agriculture is facing several concerns including climate change, soil degradation, decreasing land holding, urbanization, unsustainable use of natural resources, excessive use of agrochemicals, biodiversity loss, air pollution etc. are some of alarming issues which demand immediate interventions. Conventional agricultural practices could not handle these challenges as they are complex, labour intensive, time-consuming, less efficient, large requirements of crop nutrients and non-targeted. Furthermore, the inefficient use of agrochemicals poses a serious threat to the ecosystem. Therefore, scientists, farmers and policymakers are constantly searching for new techniques to combat existing challenges. Nanotechnology is emerging as the new savior of sustainable agriculture. Besides precision farming, nanosensors have been employed for the detection of crop pathogens and chemically harmful analytes in agri-fields. Moreover, nanorobotics and nano-barcodes have also shown a profound impact on agriculture practices to enhance the yield of agriculture. Further, tremendous applications of nanotools in agriculture are extensively im plicated in bioimaging, sensing, photocatalysis and agrochemicals delivery. This review comprehensively discusses diverse tremendous applications of nanotechnology in overcoming the challenges of conventional agronomic prac tices and future prospects of nanotechnology in agriculture.
