Stock Market Development and CO2 Emissions in Africa: The Moderating Role of Domestic Credit to the Private Sector

Received: 06 January 2026;  Published: 04 June 2026;  doi: 10.21926/aeer.2602012

Abstract

This study examines the effects of stock market development (SMC) and renewable energy consumption on CO2 emissions in nine African economies over the period 2000-2024. It also tests whether domestic credit to the private sector (DC) moderates the relationship between stock market development and CO2 emissions. Panel data econometrics, including Feasible Generalized Least Squares (FGLS) for the main estimates and Panel-Corrected Standard Errors (PCSE) for robustness checks, are used as the primary analytic techniqu [...]

Assessing Land Use Dynamics and Thermal Stress in Ahmedabad Using Integrated Remote Sensing and Machine Learning Techniques

Received: 01 March 2026;  Published: 27 May 2026;  doi: 10.21926/aeer.2602011

Abstract

The rapid urbanisation in developing countries has not only intensified land transformation but also significantly altered surface temperatures, thereby increasing climate vulnerability. Ahmedabad, one of India’s fastest-growing cities, has witnessed substantial urban growth over the past two decades and therefore requires an integrated approach to analyse land-use change, thermal dynamics, and future growth patterns. This study aims to analyse the spatial and temporal patterns of land use/land cover (LULC) changes [...]

Application of Unmanned Aerial Vehicles in Assessing the Current Condition and Closure Design of Da Mai Landfill (Vietnam)

Received: 24 December 2025;  Published: 25 May 2026;  doi: 10.21926/aeer.2602010

Abstract

Municipal solid waste (MSW) landfills remain a major source of greenhouse gas emissions, leachate pollution, and land degradation, particularly in low- and middle-income countries where many sites operate beyond their design capacity. This study proposes an integrated and low-cost framework combining unmanned aerial vehicle (UAV) photogrammetry with environmental assessment to support landfill closure planning. Using the Da Mai landfill (Vietnam) as a case study, high-resolution orthomosaics and a digital surface m [...]

Integrated Assessment and Projection of Urban Expansion and Thermal Dynamics in Bangalore Using Multi-Temporal Landsat Data and Machine Learning Techniques

Received: 12 February 2026;  Published: 19 May 2026;  doi: 10.21926/aeer.2602009

Abstract

Rapid urbanization has remarkably altered land surface characteristics and thermal environments in Indian metropolitan cities, thereby increasing ecological pressure and urban heat risk. This study integrates assessments of land use and land cover (LULC) change and LST, and the UTFVI for Bangalore, India, using multi-temporal Landsat imagery and geospatial techniques, along with machine learning methods. LULC changes were studied and analyzed for 2000 and 2020, and a simulation to 2024 was performed, employing a Ra [...]

DWSIM-Based Process Simulation and Exergy Analysis of Bioethanol Production from Rice Husk

Received: 31 December 2025;  Published: 30 April 2026;  doi: 10.21926/aeer.2602008

Abstract

The growing concerns over fossil fuel dependency have motivated the exploration of sustainable biofuel alternatives. However, the practice of utilizing first-generation bioethanol production obtained majorly from food crops threat food supply market and poses threat to food security and land use. As a way forward, second-generation bioethanol from biomass, such as rice husk, an abundant agricultural residue, could potentially offer a promising pathway. Yet, its conversion remains energy-intensive and thermodynamica [...]

Cr(VI) Adsorptive Removal Using Raw Cordia africana Sawdust: Optimization of Operating Parameters, Kinetics, Isotherm, Thermodynamics, and Desorption Efficiency

Received: 04 January 2026;  Published: 24 April 2026;  doi: 10.21926/aeer.2602007

Abstract

Hexavalent chromium (Cr(VI)) is a carcinogenic pollutant commonly found in wastewater from tanning and electroplating industries. This study investigates the efficiency of raw Cordia africana sawdust as a biosorbent for Cr(VI) removal. Batch adsorption experiments were conducted by varying pH (3-8), contact time (10-120 min), and Cr(VI) concentration (21-47 mg/L) using Response Surface Methodology (RSM) with Box-Behnken design. Characterization was performed using FTIR, SEM, BET, pH, and PZC analysis before and aft [...]

Sustainable and Environmentally Friendly Approaches for Eliminating Alizarin Red S from Contaminated Water Using Hydroxyfluorapatite-Based Biomaterials

Received: 15 December 2025;  Published: 10 April 2026;  doi: 10.21926/aeer.2602006

Abstract

This study investigated the use of new bioadsorbent the Hydroxyfluorapatite (Ca10(PO4)6OH1.75F0.25, HFA) to eliminate Alizarin Red S (ARS), a harmful water pollutant. Initial batch tests were conducted to evaluate the adsorption process, focusing on both kinetics and equilibrium behavior. Various kinetic models were applied such as: pseudo first-order, pseudo second order, the intraparticular diffuision model and external diffusion model. The modeling results proved that the pseudo-second-order model best matched t [...]

Restoring the Resilience of Water-Energy-Food Nexus Based on Desalination through Biomass Management: Case Study West Mani, Greece

Received: 03 November 2025;  Published: 01 March 2026;  doi: 10.21926/aeer.2601005

Abstract

Mediterranean regions like West Mani, Greece, face escalating water scarcity exacerbated by climate variability and seasonal tourism peaks, straining the water-energy-food (WEF) nexus. Olive cultivation, central to the region’s economy and culture, generates substantial underutilized biomass residues that increase wildfire risk if left unmanaged. At the same time, water supply increasingly relies on energy-intensive desalination and pumping. This study addresses the gap in integrated, place-based WEF nexus applicat [...]

Hydroclimatic Variability and Precipitation Extremes in Sindh under a Changing Climate

Received: 12 August 2025;  Published: 24 February 2026;  doi: 10.21926/aeer.2601004

Abstract

Sindh Province, Pakistan, is highly vulnerable to hydroclimatic extremes, necessitating a detailed understanding of its precipitation patterns for effective water management. This study assesses spatiotemporal precipitation dynamics across Sindh from 2001 to 2024 by integrating satellite-based CHIRPS data, in situ observations from the Climate Knowledge Portal (CKP), and CMIP6 climate model projections. Validation results show strong agreement between CHIRPS and ground data (R ≈ 0.87, d ≈ 0.93), confirming the sate [...]

Received: 08 November 2025;  Published: 10 February 2026;  doi: 10.21926/aeer.2601003

Abstract

Characterizing drought severity using GRACE and TerraClimate datasets is globally important because it enables consistent, large-scale monitoring of both surface and subsurface water availability across data-scarce regions. This integrated perspective supports improved drought assessment, climate change impact analysis, and informed water-resource management worldwide. The Ethiopian Rift Valley has experienced recurrent hydrological drought hazards, posing serious threats to water availability, agricultural product [...]
