To this end, different quantification tools are needed. Earlier applications showed, for instance, that the process of stakeholder mapping needed to be carefully designed and carried out at the very beginning of the assessment. Therefore, a more participatory exercise was developed for the NWSAS assessment (see section 3.5), where stakeholders were mapped and their relationships and power balances were described early in the process. For example, the organization of an additional consultation opportunity or investigation of an issue that emerges during the process may turn out to be necessary. The methodological flexibility has proved very useful in terms of adaptability, and flexibility from the side of the funding agencies and participating organizations is extremely valuable as well. Also, work under the Water Convention has been coordinated with other organizations, which has contributed to synergies between different nexus activities.
