PGAEI - Projection Global Arable Equipped for Irrigation under Shared Socioeconomic Pathways

This study introduces an Ensemble Machine Learning framework to generate high-resolution global projections of Arable Equipped for Irrigation (AEI) under Shared Socioeconomic Pathways (SSPs), revealing that future irrigation capacity is likely to decline in most scenarios due to economic and infrastructural constraints rather than theoretical food demand, thereby providing critical data for Earth system modeling and food security assessments.

Urban waste dominates microplastic pollution in Ethiopian irrigated farmlands: Evidence from FTIR spectroscopy, random forest classification, and farmer surveys

This study reveals that urban waste mismanagement, rather than industrial activity, is the primary source of widespread microplastic contamination in Ethiopian irrigated farmlands, highlighting an urgent need for improved municipal waste collection, stricter plastic bans, and farmer education to mitigate this emerging environmental threat.

A citizen science-based framework for monitoring coipo (Myocastor coypus) in Chilean urban wetlands

This study proposes a citizen science-based framework for monitoring coipo (Myocastor coypus) in Chilean urban wetlands, evaluating various methods to recommend structured sign-based approaches supported by public observations and expert validation as the most feasible and scalable solution for long-term biodiversity monitoring.

ENSO-Driven SST Warming and Marine Primary Productivity Suppression in Bali Waters: Spatiotemporal Evidence from the 2015–2016 El Niño

This study utilizes satellite data to demonstrate that the 2015–2016 El Niño caused significant sea surface warming and a 54% decline in chlorophyll-a concentrations in southern Bali waters, driven by intensified vertical stratification that suppressed nutrient upwelling and phytoplankton productivity.

Influence of Vegetation Type and Hydrology on Short-Term Nutrient Retention in Wetland Mesocosms

Using experimental mesocosms to simulate west Tennessee floodplain wetlands, this study demonstrates that while all vegetation types and flood histories achieved high five-day nutrient retention, emergent vegetation significantly enhanced short-term nitrate removal compared to tree plantings or unvegetated conditions, suggesting vegetation type is a critical factor for optimizing water quality in short-duration flood events.

The Air Pollution Tolerance Index as an Integrative Tool for Forest Restoration, Carbon Sequestration, and Biodiversity Conservation: A Review

This review synthesizes evidence demonstrating that the Air Pollution Tolerance Index (APTI) serves as a scientifically grounded, cost-effective integrative tool for selecting plant species that simultaneously enhance forest restoration, carbon sequestration, and biodiversity conservation in pollution-affected regions.

Integrated Sustainability Framework for the Adoption of Engineered Wood Products in the Nigerian Construction Industry: Evidence from Enugu State, Nigeria

This study validates an integrated TOE-TBL structural equation model using survey data from Enugu State, Nigeria, demonstrating that technology, organizational, and environmental factors significantly drive the adoption of engineered wood products, which in turn substantially enhances environmental, economic, and social sustainability outcomes in the Nigerian construction industry.

Using Nature-based Solutions in Mitigating Indoor Air Quality: A Case Study of EDM Emission from a Gear Manufacturing Unit, India

This case study demonstrates that implementing Nature-based solutions, including specialized air filters and improved ventilation in a gear manufacturing unit in India, successfully reduced hazardous CO levels by 90% and PM2.5 by 42%, though further measures are needed to bring particulate matter within healthy limits.

Dengue Vector Dynamics in India: Present and Future Multi-Model Suitability under SSP Scenarios Using a Machine Learning-Based Maximum Entropy Model

This study utilizes a machine learning-based MaxEnt model with high-resolution climate data and multiple future scenarios to project that while over half of India is currently climatically suitable for dengue transmission, future risk will likely involve a northward spatial redistribution rather than uniform expansion, highlighting that climatic suitability alone does not fully predict disease burden.
