Abstract: The concept of Net Zero Carbon Buildings, which aims to reduce greenhouse gas emissions, is essential in addressing climate change. However, the development of such buildings in Thailand faces significant challenges, including high construction costs, uncertain returns, and limited investment incentives. This study explores the factors influencing real estate developers' decisions to pursue Net Zero... More

Abstract: This study aimed to quantify the carbon footprint of the National University of Juliaca (UNAJ) for the year 2023, in order to identify the main sources of greenhouse gas (GHG) emissions and provide a foundation for implementing sustainable policies. The methodology was based on the greenhouse gas inventory approach outlined in ISO 14064-1, applying the... More

Abstract: This study introduces the Bioclimatic Emission Amplification Theory (BEAT), a novel framework for detecting and forecasting how terrestrial ecosystems, particularly the Amazon Basin, transition from being carbon sinks to becoming carbon sources under compounded bioclimatic stress. BEAT synthesizes satellite-derived data from 2001 to 2022 and integrates temperature anomalies, vapor pressure deficit (VPD), fire activity, and... More

Abstract: Climate crises necessitate adaptive, cost-effective, and community-driven strategies to enhance urban resilience. Tactical urban design, which includes temporary and experimental interventions, is becoming increasingly vital, particularly in indigenous contexts. This study explores the spatial agency approach within tactical urbanism, emphasizing low-technology techniques, indigenous knowledge, and decentralized design as active elements in transforming public spaces. It... More

Abstract: The increased erosion of mangrove forests has alarmed the government about the damage to both the economy and livelihoods. To evaluated forest and land erosion the coast. Based on survey data is divided into five levels (F1: no erosion; F2: little erosion; F3: moderate erosion; F4: high erosion; F5: strong erosion), and ecological conditions, the... More

Abstract: With over 141 million tons of packaging waste generated globally each year and limited recycling efficiency, packaging pollution has become a pressing environmental issue, driving increased scholarly interest in green packaging. However, existing studies have primarily focused on individual domains, lacking a systematic and comprehensive review, which restricts interdisciplinary integration and obscures overarching trends and gaps....

Abstract: This work investigates a combined cooling, heating, and power (CCHP) generation system utilizing waste energy. A cascade-CCHP system is developed, consisting of a 23.65-kWe organic Rankine cycle (ORC), a 4.00-kW adsorption chiller, a 4.11-kW absorption chiller, a 15.99-kW drying room, and an incinerator of 150 kg/h. A net energy production of 36.08 kWh is achieved from a... More

Abstract: This study explores the status, challenges, and opportunities of smallholder aquaculture in the Leyte Sab-a Basin Peatland (LSBP), with a particular focus on the application of Nature-Based Solutions (NbS) for sustainable management. Using a mixed-methods approach that combines a comprehensive literature review with a focus group discussion (FGD) involving 22 local practitioners, the study identifies... More

Abstract: Environmental education is gaining increasing recognition in Morocco as a fundamental pillar for achieving the Sustainable Development Goals (SDGs). Within this context, school-based environmental clubs play a crucial role in promoting awareness and building climate resilience among students at various educational levels. These clubs serve not only as platforms for ecological engagement but also as... More

Abstract: Promoting sustainable mobility and understanding travel demand are critical for rapidly growing cities like Kigali. This research aims to address limitations of traditional transport models by integrating geospatial analysis to support multimodal planning and optimize bike-sharing infrastructure. The study combines the Four-Step Transport Model with Geographic Information Systems (GIS) to enhance spatial disaggregation and identify... More

Abstract: Climate change has profoundly affected forests worldwide, contributing to increased pathogen invasions and the proliferation of forest diseases. This article presents a systematic review that investigates the intricate relationship between climate change and the prevalence of forest diseases. The study identifies climate-related factors that drive the rising incidence of these diseases. Following the PRISMA guidelines,... More

Abstract: Groundwater is critical for supplying drinking water to billions of people worldwide. However, their excessive permeability makes them more vulnerable to retaining and spreading contamination. Assessing groundwater vulnerability is crucial for sustainable management, as it aids in reducing the risks associated with contamination of this valuable resource. As a result, the primary aim of this... More

Abstract: Dug well water in the working area of the Jongaya Community Health Center often fails to meet clean water quality standards due to low pH (6.1) and high organic matter content (14 mg/L), exceeding the limits set by Indonesian Ministry of Health Regulation No. 32 of 2017, which poses a risk of digestive disorders and... More

Abstract: Sustainable alternatives have grown more prevalent due to an urgent need to address climate change, environmental degradation, and the depletion of non-renewable resources. As an inexhaustible and renewable resource, biomass has become an attractive option for energy production within the framework of a circular economy that emphasizes resource efficiency and environmental sustainability. Various kinds and sources... More

Abstract: The Western Himalaya, often termed the "Water Tower of Asia," is experiencing critical hydrological changes due to global warming. This review synthesizes current scientific knowledge on climate-driven alterations in the region’s water cycle, assessing impacts on ecosystems, agriculture, energy security, and local livelihoods. We conducted a systematic literature review of peer-reviewed studies (2000–2024) from Scopus,... More

Abstract: Sediment quality in global estuaries was reported by assessing the degree of anthropogenic input and the corresponding ecological risks. This research intended to categorize the quantities of marine pollution at the mouth of the Chanthaburi River, on the Eastern Gulf of Thailand, by examining the interactions amongst the heavy metals (Pb, Cd, Cu, Zn) and...
