“…The largest noise reduction values were 6.3 dbA, 4.9 dbA, and 6.2 dbA. Lacasta et al [29] discussed using green streets to lessen city noise. Standard remedies, like towering noise barriers or expansive areas of dense vegetation, are frequently impractical in urban settings, necessitating the consideration of other approaches.…”

There is a connection between noise reduction and roadside tree plantation. Understanding how prop-erties of trees (density, height, leaf type, crown spread, etc.) impact noise attenuation is crucial. The current study measured and compared the roadside traffic noise at various locations (with/without trees/plantations) in selected Multan areas. Eight locations (Bahawalpur Road, Expressway, Vehari Road, Bosan Road, Eidgah Road, Masoom Shah Road, Piran-Gaib Road, and Khanewal Road) throughout Multan City. A digital sound level meter (MS-6701) was used to measure the noise levels during months of winter and summer seasons. During field visits, the tree type, leaf type, average height, density, canopy crown spread, and presence of any vegetation in each designated area were noted. The sound pressure data was compared with the noise level standards as recommended by Punjab Environment Quality Standards. A clear reduction in sound levels can be observed with trees. The tree plantings reduced the noise only on the Express-way (65 dbA) and Piran Gaib Road (64 dbA) in May 2022. In June 2022, the trees were only beneficial in reducing noise near Piran Gaib Road (64 dbA). Due to tree plantation, the maximum reduction of 11 dbA was reported in June 2022 at Eig Gah Road, followed by a 10.1 dbA reduction in December 2021 at Khanewal Road. Maximum noise reduction was observed at the Expressway and Piran Gaib Roads, where Pongamia pinata and Melia azedarach are planted along with some grass. The comparison clearly showed a reduction in noise due to roadside plantations. Tree plantation helps improve the area’s overall look and enhances aesthetic sense and scenic beauty.

“…It is also essential to consider the characteristics of the urban environment [15]. Some studies prove the effectiveness of using green spaces to reduce the noise level on city streets [16]. The problem, in this case, is the questionable effectiveness of such a planning technique since it is necessary to use specific vegetation types.…”

The problem of noise pollution in cities becomes quite acute as soon as it comes to increasing the level of motorization. However, most researchers study the negative impact of traffic noise in general. In the era of sustainable mobility, there will be a trend to reduce the number of private vehicles on city streets. Still, the problem of acoustic load in residential areas will not be solved since public transport is a rather powerful source of traffic noise. The article solves the problem of determining the patterns of changes in the acoustic load from public transport vehicles at different speed modes and road surface. The article's objects of research are straight sections of public transport lines. The subject of the study is the patterns of changes in the noise level from public transport vehicles at different speeds, their position, and the type of surface. The obtained results indicate that the main range of noise pollution from public transport on straight sections is 75-85 dBA, and this level can vary by 15-20% depending on the type of line (trolley bus, bus, tram) and the type of road surface. The regularities of changes in the level of noise pollution, which were revealed in work, indicate that for each type of surface and type of public transport line, there are such values of traffic speeds, when they are reached, there is an overtime acoustic load on residential areas at specific distances from them. The obtained results differ from the currently existing scientific studies in that they consider the acoustic characteristics of clear public transport lines and not the traffic flow as a whole. Therefore, it becomes possible to determine the maximum and not the equivalent level of noise from public transport. The field of application of the results is transport planning of both new residential areas and areas of existing adjacent buildings. Thus, in the first case, recommendations were made regarding territorial gaps from the construction line to arterial streets with high volume of public transport, depending on its type and surface. On the other hand, recommendations have been established regarding the speed regime of public transport at different distances from existing buildings' lines.

Systemic innovation must be the driving force behind actions to transform cities to address climate change. It includes transformations of environmental, social, economic, financial, technical, regulatory, and governance nature, supporting the permanent change of cities. Nature-Based Solutions (NBS), can be part of the tools to address the challenges ahead. This research aims to define a framework of action in cities for the implementation of NBS, demonstrating the importance of quantifying its benefits in environmental and socio-economic terms, to boost public policy design and investment in this field. This work is divided into two parts. The first part, analyses some of the European measures in the field of sustainable development in cities, focusing the research on the case of Madrid. And in the second part, some case studies are presented to reflect the measures and actions taken to promote the implementation of NBS in the city of Madrid. As a result, the potential levers of change for the implementation of NBS are identified, highlighting the importance of quantifying their effects to demonstrate the potential value that can be generated within cities.
