At the fifth session of the meeting of the parties, a Guide to implementing the Convention was adopted. A Guide offers commentaries to the provisions, and examples of good practices. In addition to that, an Assessment was made, to show the current status of transboundary waters. The Second Assessment covers more than 140 transboundary rivers, 25 transboundary lakes, about 200 transboundary groundwaters and 25 Ramsar sites or other wetlands of transboundary importance.
