Currently, the sustainable development of rural areas is relevant for various countries, both developed and developing. The improvement of existing approaches for the assessment and management of rural settlement systems is particularly relevant for Belarus, as a country with agricultural resources. Currently, there is no eligible information model for a rural settlement system in Belarus. The main research aim of this study was to develop the information model for formulation and assessment of the settlement scenarios for solving the issue of sustainable rural development in Belarus. The research methods were based on the complex and interdisciplinary approaches, including the systems approach, factor analysis, comparative analysis, spatial and mathematical modelling, SWOT analysis, and the hierarchy method. The paper proposes the development of the informational model of a rural settlement system at a local planning level, including five main determinants of sustainability, namely social, technological, economic, environmental, and political. The model was approved by the assessment of development scenarios for the Zavalocycy local council as the first-level unit of a planning system. We obtained the development indexes for 14 rural settlements within the obtained assessment criteria. The research results showed the relevance of the informational model for the monitoring of sustainable development at a local planning level.
