In addition, regional networks such as the planned Pacific Network of Island Universities Higher Education for Sustainable Development Framework or informal networks such as the one established through the Mainstreaming Environmental Sustainability in Caribbean Universities (MESCA) audit discussed below, provide opportunities for the continued sharing of experiences between institutions for the strengthening of ESD-oriented programmes. This process has already begun, evidenced by the Network of Island Universities (NIU) EDULINK project, which brings together USP along with the National University of Samoa and the University of Papua New Guinea, resulting in new course offerings focused on thematic areas related to sustainability. As a regional centre of expertise on ESD under the UNESCO model, USP has made important contributions to advancing ESD in the region. Currently, both the Caribbean and AIMS regions lack such a centre, and one source in the Caribbean has suggested that this is something that should be explored further.
