The key factor for sustainability and full impact lies in going beyond the borders of case study regions and expanding to a wider array of relevant stakeholders. We define stakeholders as those with an interest or concern in UPSCALE, who are both impacted by it and can have impact on the project themselves. Therefore, it is a wide array of individuals, groups, institutions, and organisations (non-exhaustive) who can affect the decision-making process in the project and more importantly, outcomes.
