Dynamics of the international environmental treaties - perspectives for future cooperation

International treaties and multilateral agreements are undoubtedly based on networks, which, considering the magnitude of the environmental issues or resources conflicts that we are facing, become complex networks. Implementing a strategy that easily integrates all these problems is particularly difficult to develop or apply, and the disengagement has no way to help. To achieve successful environmental governance is only possible with the involvement of all parties or stakeholders. This paper illustrates the evolution of the cooperation network established between the international parties that ratified the most important environmental treaties at international level discussing transboundary issues. By applying a network analysis perspective, we explore the dynamics of the cooperation considering 3-time intervals, namely: collaboration for the implementation of the treaties before 1990 (1), before 2000 (2), and before 2020 (i.e., the cooperation established so far within the most common environmental agreements). We further examine the network structure by investigating the core-periphery model, which shows the current situation in terms of level of involvement in the ratification and application of the principles of the international environmental treaties established. Our findings suggest that a complex and more functional system is needed to manage both common biodiversity resources and solve existing transboundary environmental conflicts.
