“…Interestingly, rather than focusing solely on environmentbased concepts of effectiveness, the IEA institutions tend to adopt a multi-track perspective on effectiveness. Apart from the expected sustained focus on developing environmental indicators and establishing baseline information and trends in the identified environmental indicators (Seelarbokus, 2014), effectiveness is also often analyzed in terms of proxy effectiveness indicators such as the number of meetings or seminars held, joint research programs established, country reporting successes, participation rates, and the number of agreements negotiated under the parent convention, inter alia. The CMS Secretariat, for example, considers that the CMS treaty has been successful in view of the seven additional agreements negotiated under the ambit of the main CMS treaty, the growth over the years in the number of contracting parties, MoUs agreed upon with other IEA Secretariats or international NGOs, the establishment of coordinated aerial surveys to study the seal population (in regard to the Seal Convention), as well as the status or trends in the population of the other relevant species (Reijnders et al, 2009; UNEP/ CMS, 1997b).…”
