ABSTRACT An increasing number of cities in Germany and Europe are formulating adaptation strategies to address the consequences of climate change. Nevertheless, quantifying whether these strategies contribute to alterations in urban infrastructure and promote climate‐sensitive urban development is challenging. This article aims to explore possible urban climate adaptation indicators (UCAIs) from literature suitable for assessing the implementation of heat‐ and water‐sensitive urban development measures in local municipalities, with a focus on Germany. In addition to a literature review, workshops and discussions with experts from Germany complemented and deepened the indicator selection process. As a result, we identified 27 indicators, which were grouped into 5 key areas: (1) surface and urban overheating indicators; (2) building type and structure indicators; (3) green infrastructure indicators; (4) soil‐sealing indicators; and (5) water‐sensitive urban development indicators. Only a few manage to map several adaptation measures, avoiding conflicts with other urban planning objectives, can be derived for cities at the national level and show promise for capturing small‐scale adaptation measures in the city. We concluded that, in particular, the green infrastructure and soil‐sealing indicators, such as green cover, access to greenery and green supply have a high potential to meet heat‐ and water‐sensitive urban development goals, while avoiding conflicts of objectives and trade‐offs. Overall, this review underscores the necessity for additional research and testing to formulate practical and effective indicators for capturing heat‐ and water‐sensitive aspects of urban development.

Introduction: Climate change poses a significant global health threat impacting regions unevenly based on their vulnerabilities. India, with its distinct geography and climate, is particularly at risk. This study aimed to assess the knowledge, attitudes, and practices of healthcare workers regarding climate change and its impact on, human health, with a specific focus on the National Programme for Climate Change and Human Health. Methodology: This was a cross sectional study, conducted among healthcare workers in Datia, Madhya Pradesh. Healthcare workers at the Medical College and District Hospital in Datia were given a semi-structured questionnaire via Google Form between October 1 and October 30, 2023. The total eligible population for participation was approximately 200 healthcare workers, including teachers from the Medical College, PG residents, and medical officers from the District Hospital, Datia, Madhya Pradesh. Results: The analysis revealed that 62.5% of participants were aware of NPCCHH, with 52.4% understanding its objectives. Moreover, 79.2% displayed positive attitudes towards climate change, emphasizing the need for awareness about climate changes impact on vulnerable communities. While a minority (29.2%) engaged in climate change related awareness programs and 20% monitored air quality index (AQI) daily, the majority (70%) practiced eco-friendly activities like recycling, conserving water, and using energy efficient appliances daily. Conclusion: Lower knowledge levels among postgraduate residents highlight the need for targeted educational initiatives. Finding of positive attitude among all healthcare worker groups signal encouraging environment for future climate change interventions. The variation in practices among groups suggests a need for formal training programs on heat-related illness and air pollution monitoring.

Study region: The Tibetan Plateau (TP), China, contains the world’s largest permafrost area outside the Polar Regions. Study focus: This study investigates the precipitation-induced advective heat flux (EPre), which represents the energy transfer resulting from the temperature difference between rainfall and soil. Observational data from three permafrost monitoring sites (Qumalai, Xidatan, and Tanggula) were combined with simulations from the Community Land Model version 5.0 (CLM5.0) to quantify EPre precipitation infiltration depth, and the probability of infiltration reaching the frozen soil layer. The analysis further examines how precipitation amount, soil texture, soil moisture, and freeze–thaw state jointly control infiltration processes and influence the soil thermal regime. New hydrological insights for the region: Infiltration depth varies with initial soil moisture and precipitation duration, from shallow retention to deep percolation. EPre is generally negative, with maximum cooling of −84.14 W m⁻² at QML, −73.24 W m⁻² at XDT, and −56.63 W m⁻² at TGL, but becomes positive during prolonged summer rainfall, reaching 45.43 W m⁻² at QML. Diurnal soil temperature variations shift EPre from cooling by day to reduced cooling or warming at night. Across the TP, mean infiltration depth is ∼5 cm, higher in southeastern Tibet, with a regional mean EPre of −0.08 W m⁻². Warming effects are concentrated in the southeastern and central TP, while cooling dominates the arid west and high-elevation north.

Abstract Mine tailings are an unavoidable waste generated during iron ore mining operations, of which millions of tonnes are generated worldwide. Given the importance of steel, and therefore, iron ore mining, solutions are needed to recover this waste. Despite global efforts, the current proposed solutions struggle to reach the market due to cost-effectiveness issues. This study explores a potential solution, presenting iron tailings as a viable, economical, and sustainable material for thermal energy storage systems. Thermal characterization showed a specific heat capacity of 780–990 J/kg·K up to 590 °C. The material remained thermally stable without melting or decomposition up to 1000 °C, and the resulting storage density was estimated up to 450 kWh/m3. The material stands up safety, minimal environmental impact, and favourable thermophysical properties at a low investment cost. This innovative application not only addresses energy challenges but also contributes to resolving the waste management crisis in the iron mining industry.
