Landfill monitoring is one of the most important components of waste management. This article presents a case study on landfill monitoring using remote sensing technology. The study area was the Glina landfill, one of the largest municipal waste disposal sites in Romania. The methodology consisted of monitoring the differences of temperature computed for several distinct waste disposal zones with respect to a ground reference area, all of them located within the landfill site. The remote sensing data used were Landsat satellite multi-temporal data. The differences of temperature were computed using Landsat thermal infrared data. The study confirmed the use of multi-temporal Landsat imagery as a complementary data source.
To achieve a succesful energy transition, the collaboration of all stakeholders and policies for decarbonization at all levels are required. In this context, we aim to assess the perspective of energy transition in marginalized urban areas in Romania. The research is based on findings from a consistent analysis of 37 local development strategies in Romania in terms of energy (electricity and heating service provision). Despite the issues identified, we detected that communities across the country showed limited interest in renewable energy, which may be linked to low levels of awareness and education of residents in marginalized communities. In parallel with the analysis of the strategies, we developed Romania’s maps for renewable solar resources. Then, we developed maps of energy potential by linking the map of marginalized communities with the map of renewable energy resource potential in Romania. In addition, we used the PVGIS solar radiation tool to generate results related to median solar radiation estimates. Finally, we concluded by proposing a roadmap for potential energy projects in marginalized urban areas and providing recommendations for (i) Managing Authorities to support project preparation for future Operational Programmes and for (ii) the urban Local Action Groups.
The deployment of automated vehicles (AVs) has the potential to disrupt and fundamentally transform urban transportation. As their implementation becomes imminent on cities’ streets, it is of great concern that no comprehensive strategies have been formulated to effectively manage and mitigate their potential negative impacts, particularly with respect to the components of the do no significant harm (DNSH) framework recently introduced in the EU taxonomy. The methodology employed comprises three steps: (i) An extensive literature review on the impact of AVs on the DNSH components; (ii) exploration of designing a coherent pro-active vision by integrating measures identified in the literature as key elements to mitigate the harm; and (iii) an interdisciplinary focus group (FG) to verify whether the impacts of AVs and potential mitigation measures for Bucharest are similar to those identified by the literature and integrated into the pro-active vision. The results suggest that while there are commonalities, variations exist in focus and perspective, underscoring the necessity of examining the mitigation measures encompassed in the vision through additional focus groups conducted in different cities.
ABSTRACT:3D geo-information is essential for urban climate studies. It is obvious that both natural environment and built-up environment play the fundamental role in defining the climatic conditions for urban areas, which affect the quality of human life and human comfort. The paper presents the main categories of 3D geo-information used in urban climate studies and roles in creating and operating the numerical models specially designed to simulate urban planning scenarios and improvement of the urban climate situation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
