Are there any obstacles addressed which might impede a transnational sustainable spatial development in the sense of lacking of joint transnational activities as well as a missing understanding of the SSD requirements.

Administrative, legal and cultural differences, lack of cross-border coordination, data and statistics and lack of accessibility account for more than five entries, whereas all other obstacles are only sporadically mentioned.
