“…HSRs are a massive boost to socio-economic growth and the most significant transport mode, they are cheaper than air transportation, reliable, have standard facilities, create less CO 2 emissions than aviation, and are safe and green [6,7]. Carbon emission significantly impacts human health and the environment [8,9] and should be considered a part of the Sustainable Development Goal (SDG 11) by monitoring or reducing air pollution [10]. HSR projects have substantial implications on passengers and products, foreign commerce, and transport.…”

Since the Belt and Road Initiative (BRI) has been put in practice by the Chinese government, several High-Speed Railways (HSR) have been built by Chinese Engineering Procurement and Construction (EPC) firms. However, many delays have created severe detrimental consequences on the progress of most HSR projects. This study sought to explore the essence of the recurring triggers of delays in international EPC HSR projects under the BRI, and a structured questionnaire survey approach was applied to compile the first-hand dataset from Chinese EPC firms working for BRI infrastructure projects. The data were evaluated, and the Relative Importance Index (RII) was adopted to assess the magnitude of the important delay triggers. The findings suggest that HSR projects are still susceptible to unavoidable delays in global construction infrastructure projects. In the engineering phase, improper management of the design, unsustainable land acquisition, and insufficient use of EPC joint venture are the salient trigger of delays. In the procurement phase, the leading causes of unsuitable procurement, undervalued procurement cost, inefficient logistics in labor and materials, improper planning, unqualified site supervisors, inefficient technical standard management, and inefficient constant payment terms are likely to trigger delays in the construction phase HSR projects. Five critical groups of delay factors are identified by this study, which has an essential primary contribution to the body of knowledge and is helpful to EPC contractors working for HSR projects under BRI.

Ahmedabad city struggles with one of the highest ambient air pollution levels in India. To reduce the air pollutants, urban green spaces can be considered one of the best options. In the study, few physical variables, like plant stature and morphology, are considered. This paper covers the aspect of vegetation for analysing pollution mitigation. Four Urban Forest (UF) sites from four different zones, differentiated by the land use of each site, of the city of Ahmedabad have been selected, Physical variables of each of these Urban Forest sites were collected. Consequently, an air monitoring station was selected from within 4 km radius of these sites. The selected urban forests were introduced in 2019-20. Pollutant concentration data from before UF and after UF (2016-2021) of each site was extracted from all the stations. This data was then compared with the physical variables of UF to determine the AQI change in the area throughout the years. The findings showed improved the concentration of pollutant in each of the 4 sites. Factors like number of trees and tree species in each site played an important role in pollutant reduction. To understand the role of urban forests, NDVI analysis was conducted of the sites.
