It is substantiated that the institutional concepts of the latest institutional and behavioural economic theory should be placed in the methodological basis of the development of the institutional environment of the land management system. Institutions and institutes are the key to understanding the relationships between all subjects of the economic system of land management, and institutional changes determine the direction of its development and are a defining trend today. The institutional system in the field of land relations, land use and land management is a set of organically interconnected institutions and institutes that are a certain logically complete, integral unity, capable of self-development and self-reproduction, as well as organizations and individuals that act within given institutional restrictions regarding land relations and organization of land use. Firstly, the methodology of institutionalization of land management considers socio-economic systems through holistic development. The principle of the integrity of the socio-economic system research includes an interdisciplinary approach. Secondly, individuals receive characteristics through the prism of the existence of institutions and institutes that condition their behaviour and interaction. Thirdly, institutional changes require not only quantitative, but also qualitative methods of observation, which analyse not the results of changes (for example, indicators of efficiency and growth), but the direction, strategy and the very process of evolution with the clarification of the causes, all stages and forms of transformations.

This article examines the impact of the Russian Federation’s full-scale aggression in Ukraine on the market of land surveying and topographic-geodetic services. The study found that the market for land surveying services decreased by 60–70% due to restrictions in the functioning of the land cadastral system, the introduction of the permit procedure for field geodetic works, and the adaptation of procedures for granting land to citizens during wartime conditions. Technological limitations, such as the use of GNSS networks at the beginning of the war, also played a role in the decline of the industry. The article highlights the prospective needs for land surveying work for post-war reconstruction, including accounting for war damage and mapping affected territories, spatial planning for affected communities, infrastructure restoration, and land reclamation in areas where hostilities took place. The article provides insights into the challenges and opportunities faced by the land surveying industry in Ukraine during wartime conditions and emphasizes the importance of adopting appropriate strategies for recovery and growth. It is shown that despite the war, the development of the industry depends on further digitalization, improvement of the cadastral system, gradual liberalization of access to cadastral geodata, the introduction of special rules for regulating the activities of the surveyor in the territories where hostilities were fought.
