I strongly recommend the proposed additional session because all the four papers for the session are of high quality, and the additional and the original regular sessions complement each other very well. The papers in the additional session cover more socioeconomic and spatial aspects in the process of internal migration and urbanization, and therefore its addition will provide more comprehensive and in-depth knowledge on the original regular session's theme.
The order of the four papers needs to be adjusted but I cannot do it on the screen.
