The Global Commission on Healthy Indoor Air is a transdisciplinary alliance of more than 200 leaders and experts from more than 40 countries across every region of the world. Launched at the United Nations during Climate Week on September 23, 2025, the Commission brings together leaders spanning public …

Predicting flood dynamics in data-scarce urban catchments remains a major hydrological challenge, yet physically-based modeling is essential for design mitigation infrastructure. This study assessed the impact of land cover change on the hydrological response and hydraulic performance of the ungauged …

Conventional centralised sewerage systems are increasingly challenged by climate change, population growth and sustainability goals. Decentralised wastewater treatment systems (DWTS) offer an alternative by reducing hydraulic loads, enabling local reuse and supporting resource recovery. This study analyses …

Urbanisation and climate change increase the need for quantitative insight into the contribution of nature-based solutions (NbS) to climate adaptation. While NbS are widely implemented at local scales, their aggregated contribution to regional and national adaptation ambitions remains largely unknown. …

Cape Town faces a complex and interlinked set of climate-related challenges, including recurring droughts, flooding, intensifying heat stress and biodiversity loss. These impacts are further amplified by rapid urbanization, pollution (often due to poor infrastructure and service delivery), ageing water …

The Vietnam Mekong Delta (VMD) is an essential region providing food security. According to The World Bank (2024), the Mekong Delta is the Vietnamese centre of rice production, with 50% of the country’s rice production and 90% of exports. Besides its agricultural activity, VMD is also an important aquacultural …

Within the Cool Neighbourhoods project, heat stress is assessed using the Physiological Equivalent Temperature (PET), a thermal comfort indicator that combines meteorological conditions with spatial and environmental variables. PET-based heat stress maps provide insight into spatial differences in thermal …

Though the problem of water risks is growing and becoming more evident, there is a lack of structured information about how these risks are managed through the certification process. While there are certain credits dedicated to managing water risks and implementing measures in regard to them in the …

This study compares three farm-scale biogas utilization pathways—combined heat and power (CHP), biogas upgrading, and bio-methanation—using process simulation and life cycle assessment to identify the most suitable option for on-farm application. Bio-methanation showed the highest practical energy efficiency, …

This study investigates the integration of biochar production with CCS as a hybrid biomass-based CDR pathway that could enhance net carbon sequestration while reducing pyrolysis-related CO2 emissions. Biochar and BECCS are often treated as separate options, even though they rely on similar biomass supply …
