Yemeni cities are distinguished by their ancient history and rich traditions in terms of the organization of urban recreation, which are not well studied and therefore are not used in modern city planning. The developed concept of the recreational framework of Sana'a was developed on the basis of data from a comprehensive system analysis of the planning structure of the city, the identification of the national identity of the Yemeni landscaping structure, the integration of climatic, dendrological and landscape conditions, as well as social factors influencing the organization of urban recreations of Sana'a. Based on the analysis data and identified architectural and planning opportunities, the key principles for organizing the "green" recreational frame of the city of Sana'a were proposed.

The topic of BIM is relevant for the present and is inseparable from the issues of infrastructure development and Smart Cities development projects. Our country is on the path of digital transformation and the development of information technologies in all its fields of activity. BIM technologies are being introduced into the construction industry and will be developed through the promotion of the state. BIM technologies create information models that are implemented through infrastructure projects. This process creates the basis for smart cities. Within the framework of the work, the directions of development in "Smart cities" were highlighted, the positive effects of BIM technologies were considered.

The article discusses the development of tourism in the Syrian seaside region, which includes many natural, historical and cultural monuments and traditions. Therefore, based on the methods of field analysis, mapping and studying the development plans of the Ministry of Tourism of the Syrian Arab Republic, in this article we will identify the problems of land use, planning, management and investment in tourism. Based on the results of the consideration of the problems, the article presents an assessment of the state of the tourist infrastructure, conclusions are drawn about the need for new approaches to its spatial organization, purposeful planning and management of tourist activities within the boundaries of the entire territory. Therefore, in order to create an attractive, stable and safe tourist and recreational environment, it is necessary to plan a sustainable and well-managed development of coastal tourism, so that all these elements become beneficiaries, not victims of tourism development, allowing countries, especially developing countries, to resist competition in the international market.

Many sources of environmental pollution affect human health. The concentration of harmful substances constantly changes during the day when the weather conditions change in different parts of the territory. Residents can repeatedly enter and leave areas of increased pollution without noticing it with their senses when moving around the city. The authors analyzed the existing solutions for monitoring the quality of atmospheric air, as well as key sources of pollution and their distribution in the air. The interrelation of distribution of pollutants with weather conditions is noted. Preparation of data on the presence of harmful substances on the example of the city of Volgograd has been carried out. A method for organizing monitoring of harmful substances in the atmosphere using a software and hardware complex is proposed. The developed method was applied to create a specialized web application. The implemented solution allows to monitor the state of the environment using sensors and build routes around areas with a high concentration of harmful substances.
