Keywords:natural landscape, visual impact assessment, visual pollution
Fulfilling the requirements of European Landscape Convention and following the statements of the National Landscape Policy of the Republic of Lithuania in 2014 the Ministry of Environment of the Republic of Lithuania intitiated the creation of Methodology of the Assessment of Visual Pollution to Natural Landscape Complexes and Objects. In order to prepare the Methodology legal and theoretical framework of visual impact assessment (VIA) was analyzed and evaluated. Summarizing the analysis of the legal framework it can be said that national legislation requires the avoidance of visual pollution, but there are no recommendations how to evaluate visual impact. Foreign countries in the field of VIA, unlike Lithuania, have validated concepts of landscape visual quality and planned activity or object visual impact assessment; methodological recommendations of VIA, based as much as possible on principles of objectivity and systematicity, which are used in practical activities of planning and design. Methodologies used by Lithuanian authors are well developed theoretically and intended for the overall evaluation of landscape visual quality or VIA, designation of landscape visual quality classes, evaluation of visual spaces (VS) indicators, establishment of VS visual resistance and sensitivity. Parts of some works can be used for creation of methodology of visual pollution (negative visual impact) assessment.
