Todays, society and states no longer accept following trends of globalization because of its contradictions. In fact, exacerbating challenges such as extension of poverty, underdevelopment, crime, environmental pollution, ethnic and religious conflict in different regions of the world, role of local actors especially cities alongside other nongovernmental actors have been considered seriously both in terms of place of administrative activities and hidden inner potentials of institutions and civil society associations in them. The new approach called "glocalization" has been proposed. It is a compound approach of two phenomena of localization and globalization in which local actors can play an effective and important role against regional and global challenges such as conflict prevention and management, peace negotiations initiation, efforts for sustainable development promotion and poverty reduction, convergence increasing between ethnicity and nations and environmental crises solving in regional and global scale. This study in analytical-descriptive method and according to reliable sources seeks to answer the question of what factors and grounds are needed by local actors to play their roles and what are the economic, social and political effects and consequences of glocalization? . Results of this study indicated this approach will have an important role to make more inclusive and integrated development, peace and security and develop more stable economic and political environment at the world, if administrative requirements of the approach including traditional diplomacy reforms, focusing on cultural issues, urban governance, democracy and civil society, resource management and financial mechanisms are considered.
