The development of urban green infrastructure (UGI) creates a better management system that greatly impacts social values in an urban system. The UGI and construction activities are receiving much attention for their effectiveness in addressing various urban ecological, social and economic issues. Using green infrastructure in stormwater management can reduce the influence on urban sewerage systems and, eventually, on building water resources. The main goal of the research is to optimize the green infrastructure to provide a less-pollution, well-organized, and pleasurable environment for the inhabitants. Various models are used to study the present rainfall-runoff scenario, but the stormwater management model (SWMM) is the most preferable and suggested model. Once the parameters are accessed, optimizing the green infrastructure (GI) will be easy. A complete SWMM model is evaluated over the complete surface, and a hydrological measurement is presented. The evaluation study presents various component percentages: asphalt (37%), green (27%), ceiling (21%), grit (12%), and cemented area (2%), which provides rainproof coverage of approximately 60%. A design is developed about the diverse events of GI in urban exploiting the SWMM and demonstrates its stimulus on the rainfall-runoff behaviour. In recent years, very little attention has been given to green spaces in urban areas, which not only increases pollution but also decreases the urbanization. Therefore, urban green spaces are more important to improve air quality and resident living standards. Over the given scenario and the rainfall event, a decline of the quantitative discharge parameters is evident, such as discharge volume (i.e., from 3.6 to 61.8) and the peak discharge rate (i.e., from 5.4 to 62.7%). The simulation results show that green areas give high satisfaction with low construction costs, which shows the superlative performance ratio of the examined measures. From the investigation, it is also recommended to have green areas and public spaces in impervious urban areas, which greatly reduced the runoff in the project area.

According to the World Health Organization (WHO), approximately 1.4 billion adults were insufficiently physically active in 2016, with detrimental impacts on health. The proposed study investigated the use of telepresence-robot-based personal trainers to facilitate remote exercise during the pandemic-related lockdowns. Several adults aged 18-65 were recruited for a four-week intervention and thorough research investigation. The intervention involved one-hour outdoor exercise sessions held three times per week in a local park with a human instructor connected via a telepresence robot. Surveys assessed perceptions of social presence, usability, the intention to use the robot and the psychological benefits of access to green space. System logs tracked participation and technical errors. At baseline, 30% of the participants met the WHO physical activity (PA) recommendations, compared to 80% after the intervention. The study shows significant increases in many parameters. These are perceived in social presence (p < 0.021), usability (p < 0.04), intentions for long-term use (p < 0.05), and the mental health benefits of accessing green spaces (p < 0.013). Attendance was found to be 90%, with a 7% technical failure rate. This investigation demonstrates the promise of telepresence robots for safely providing remote access to green spaces. They can be used to facilitate exercise during public health crises, overcoming the barriers to maintaining PA.

The methods included case studies representing different recreational landscape typologies, observational analysis and 85 on-site interviews (46% Saudi, 54% migrants). The findings outline the benefits of visiting as a retreat from busy lifestyles, for everyday sociability, for improving health, for religious practice and for mutual support, highlighting dimensions of gender, transnationality and heritage. The paper explores place attachment related to displacement comparing between impacts of migration and of rapid urbanisation. The narratives suggest that experiences shaped by temporality and memory inform emotional geographies for both Saudi and migrant residents. There are differences in patterns of use between resident groups, but the paper concludes that, within a highly stratified society, the public open spaces of Jeddah provide an important resource of shared pleasures and everyday multiculture.

However, in the Saudi context, the assessment role of UGSs (such as urban parks and gardens) and their use and accessibility has remained unexplored. This study aims to assess the use and accessibility of five urban parks in the Jeddah megacity of Saudi Arabia from diversified perspectives. Data were collected through a primary survey and questionnaire method using a social preference approach (SPA). Correlation analysis and factor analysis were performed to assess the relationship between activities and services (benefits) provided by urban parks and to examine their most significant benefits. A Kruskal-Wallis (K-S test) test was performed to determine significant differences in the perceived valuations of park benefits. A benefit dominancy index (BDI) was also developed to determine which urban parks provide the most benefit. The findings of the study showed that (i) the urban parks were mostly used for spending time with relatives (partners) and friends, followed by mental refreshment and relaxation, physical activity, and spending time with children; (ii) there are substantial seasonal variations in park visits in the Jeddah megacity; (iii) socio-demographic attributes largely affect the use of urban parks; and (iv) there are also substantial discrepancies between importance and performance related to urban management strategies. Thus, the findings of this study show that city planners and policy makers must focus on the enhancement of UGSs for the well-being of urban citizens.

Since Unmanned Aerial Vehicles (UAVs) generates a massive quantity of the multimedia data, it becomes a part of IoMT, which are commonly employed in diverse application areas, especially for capturing remote sensing (RS) images. At the same time, the interpretation of the captured RS image also plays a crucial issue, which can be addressed by the multi-label classification and Computational Linguistics based image captioning techniques. To achieve this, this paper presents an efficient low complexity encoding technique with multi-label classification and image captioning for UAV based RS images. The presented model primarily involves the low complexity encoder using the Neighborhood Correlation Sequence (NCS) with a burrows wheeler transform (BWT) technique called LCE-BWT for encoding the RS images captured by the UAV. The application of NCS greatly reduces the computation complexity and requires fewer resources for image transmission. Secondly, deep learning (DL) based shallow convolutional neural network for RS image classification (SCNN-RSIC) technique is presented to determine the multiple class labels of the RS image, shows the novelty of the work. Finally, the Computational Linguistics based Bidirectional Encoder Representations from Transformers (BERT) technique is applied for image captioning, to provide a proficient textual description of the RS image. The performance of the presented technique is tested using the UCM dataset. The simulation outcome implied that the presented model has obtained effective compression performance, reconstructed image quality, classification results, and image captioning outcome.

Without active participation in forestry, conflicts between the various stakeholders are foreseeable. The impact of forests on human life is unforgettable, and everyone gets enormous benefits from trees and greenery. COVID-19 has caused many changes in human behavior, which needs much attention. Environmental change's impact is considered a better solution and influences human behavior. Scientists around the globe are conducting research experiments on trees and the effect of forestry on human health, which is increasing in terms of social, ecological, and economic services. Trees provide full support to enhance the quality of life and minimize air pollution. Forests must be noticed to get benefits (e.g., carbon storage, fruits, human health considerations, economic benefits, and biodiversity). This research aims to explain the area of forest and health from the perspective of Saudi Arabian forestry and develop...

Currently, the deficiency of such spaces is decreasing daily, especially in urban regions. Urban green spaces (UGSs) have become a topic of great importance in enhancing life expectancy and health. To overcome these issues, the current research highlights the importance of UGSs for the residents’ living quality and urban health. UGSs are relevant for analyzing and investigating better urban lifestyles and development. To perform the experimental work, a green laboratory (GL) in a smart city (SC) area was involved in the investigation. The GL was made of wood, and different types of green infrastructure were analyzed. The research investigation resulted in upgrading the locality. Semi-structured interviews were conducted to enhance the quality of the research. Interviews with residents, occupants of offices, and government experts were conducted. Special survey questions, i.e., quantitative and qualitative, were de...
