Yemeni cities are urbanizing so rapidly that there will soon be no room for green spaces. In this regard, there is a need to find solutions to provide citizens with the "green" infrastructure necessary for life and health. This article presents the results of an urban planning analysis of the study of existing territorial reserves suitable for the formation of the "green" frame of the city of Ibb, their capacity and structure. Based on the analytical data obtained, the concept of the "green" frame of the city of Ibb was proposed, on the basis of which the system of architectural and urban planning principles for organizing the "green" recreational frame of the Yemeni highland cities was expanded and supplemented.

Cities are born, grow, develop and, of course, age. The older the city, the more often it faces the problem of dilapidated housing stock. The desire to improve the urban environment requires a solution to this problem. Currently, two main directions are used: reconstruction (by which we mean improvement, modernization, but preserving the structures and the existing planning concept) and renovation (demolition and new development). An analysis of urban planning practice in the regions of the Russian Federation made it possible to establish that in 98.7% renovation is used to solve the problem of obsolete housing stock. In the course of visual observation, field study of the renovations carried out, approaches to obsolete buildings, urban planning and, in correlation with them, social problems that cause a deterioration in the level of comfort of the urban environment were identified.

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.
