Some research issues in landscape architecture

After systematizing the development of harmonious and sustainable landscape architecture, problems in the world and the situation in Lithuania in the period of 1991-2021, it has been established that practical projects of landscape formation are less and less supported by research results and recommendations. This inevitably avoids the primitiveness of solutions, functional unreasonableness, and the opportunity to create objects of higher artistic value and ecologically based green infrastructure. The authors of this article have independently conducted research in various sectors of landscape architecture. This article aims to take a broader look at some aspects of landscape research issues in Lithuania and to present priorities for research needs. It is noteworthy that the topicality of research is reviewed by the various experiences of content researchers. If P. Grecevičius’ experience is already 45 years old, then V. Vaikutė Eidimtienė is just finishing her doctoral dissertation. This allows the authors to more accurately evaluate the many years of research experience, to take into account the latest global trends in the field of landscape architecture research
