Work Package 1 (WP1) is responsible for the transdisciplinary co-creation of innovations in ALLs. Key activities implemented included stakeholder mapping, assessment of existing multistakeholder initiatives and in some cases, early phases of a visioning exercise. National and local multistakeholder events, review of existing documentation, semi-structured interviews and focus group discussions were used to varying degrees by each country for the above activities. Agreements were negotiated with key national stakeholders in some countries to foster and clarify their active participation in the Initiative and in the decision-making regarding ALL identification and establishment. This report presents a reflection about the challenges faced so far with stakeholder engagement and ALL establishment.
