This study developed future regional Intensity-Duration-Frequency curves for Sri Lanka using climate change scenarios to address the growing need for adaptive infrastructure planning. Rainfall projections were generated with the CNRM-CM6-1 global climate model under Shared Socioeconomic Pathways (SSP) for moderate (SSP2-4.5) and high (SSP5-8.5) emissions. These projections were bias-corrected using a linear scaling method and analyzed across eleven hydro-meteorologically homogeneous regions. IDF curves were constru [...]

The presence of arsenic in groundwater poses a significant threat to public health, particularly in rural areas lacking access to treatment technologies. In Mórrope, concentrations exceeding regulatory limits have been detected, necessitating sustainable solutions. The objective of this study was to evaluate the efficiency of sugarcane bagasse as a biosorbent material for removing arsenic from contaminated waters in the Mórrope-Lambayeque district. The experimental design employed a 2 × 3 × 3 factorial design, enco [...]

Amid accelerating Arctic warming-occurring at nearly four times the global rate-cold-region infrastructure faces escalating risks from permafrost thaw, sea-level rise, and compound climate stressors. This study presents a 25-year (2001-2026) review combining bibliometric analysis with a six-nation comparative synthesis to evaluate infrastructure vulnerability, engineering adaptation strategies, and policy implementation gaps. A dataset of 1,077 Web of Science records is analyzed using VOSviewer to map thematic evol [...]

Sustainable construction practices and robust waste management strategies provide a viable pathway to mitigate these challenges. By integrating resource-efficient design, circular economy principles, and environmentally responsible technologies, the industry can significantly reduce its ecological burden. This paper presents a synthesis of environmental impacts from construction and a practical playbook of interventions spanning design, delivery, operations, and end-of-life. The study is organized as a systems guid [...]

This study evaluated the dynamic performance of raw Cordia africana sawdust for hexavalent chromium (Cr(VI)) removal in a fixed-bed column system under varying operating conditions, using both synthetic solutions and real tannery wastewater. This represents the first comprehensive investigation combining fixed-bed operation, real wastewater validation, triple-model comparison, speciation analysis, and regeneration assessment for this locally abundant Ethiopian biomass. Fixed-bed column experiments were conducted at [...]

Increases in greenhouse gas emissions, a key indicator of climate change, pose significant risks and uncertainties for the agricultural industry. From a theoretical supply-side perspective, greenhouse gas emissions may be associated with agricultural productivity losses and, consequently, with potential upward risks for producer prices. However, the Toda-Yamamoto framework used in this study tests predictive Granger causality rather than the magnitude or sign of a structural price effect. This study examines the pr [...]

A Considerable amount of peel, rind, core, and fibrous residues are produced from the processing of Jackfruit (Artocarpus heterophyllus Lam.), which are generally discarded, though they contain valuable lignocellulosic components. Limited information is available on the composition of the combined jackfruit processing waste stream. Thus, the present study evaluates the physicochemical and lignocellulosic properties of jackfruit processing waste obtained from local markets and prepared with equal proportions of peel [...]

Urban thermal environments reflect the relationship between land surface temperature (LST) and anthropogenic activity. The present study analyses seasonal land surface temperature, the Urban Thermal Field Variance Index (UTFVI), and night-time radiance in Jaipur, India from 2014 to 2025 using Landsat 8 Collection 2 and VIIRS Day/Night Band datasets. The Summer (April-June) and winter (November-December) median composites were generated for continuous analysis and for classified assessment. In the study, five LST an [...]

Climate variability and environmental change have increasingly become critical challenges affecting agricultural sustainability and global food security. Rice yield is particularly sensitive to climate-related factors, including rainfall variability, temperature changes, and environmental pressure. In Malaysia, rice cultivation is central to national food security and rural livelihoods, yet it remains exposed to changing climatic and environmental conditions. This study examines the relationship between climate var [...]

Wastewater from stamped batik (batik cap) — the block-printing method that dominates micro, small, and medium enterprise (MSME) production across Southeast Asia — is commonly discharged without a transferable design basis for continuous-flow scale. This study links batch-scale electrocoagulation-filtration (EC-F) kinetics to operational current-density projections for a 1 m3/day wastewater treatment plant, complemented by techno-economic and carbon footprint assessments. A 2 × 3 factorial batch experiment with alum [...]
