Sustainability and regional security in the context of Lithuania

The article explores the relationship between sustainable development and the regional security complex. Problems of sustainability are widely analysed since the goals of sustainable development are based on the same principles that are relevant to every country. Implementation of the sustainable development goals contributes to the understanding that the contemporary lifestyle, consumption, globalisation and the use of natural resources may have a significant impact on the quality of life of future generations. Therefore, the state’s responsibility is to ensure economic, social, environmental, cultural and political security for the present and future generations in all regions. However, the regional security complex has not been analysed sufficiently. The goal of this article is to analyse the relationship between sustainability and regional security in terms of the situation in Lithuania with regards to its economic, social and military security. The regional security complex and sustainable development may be determined and analysed by way of observing the same factors and indicators. Indicators describing economic, social and political security are analysed to reach the objective of the article. Authors of the article have chosen segmentation and classification methods such as decision making trees to conduct the research. The results of the analysis demonstrate that the economic and social factors are directly related to the political (military) security in the regions of Lithuania. Therefore, further research could focus on clarifying the full regional security complex that is relevant to each region in Lithuania
