This is the final impact report for the North South Research Programme. It showcases the impacts that have been achieved by the 62 projects funded under Call 1 of the North South Research Programme (NSRP) and demonstrates the value of an all-island approach to research and innovation. Within this is the research programme on SE: Understanding the Social Entrepreneurship Ecosystem on the island of Ireland - a research project jointly supervised between UU and ATU. NSRP funding to date has totalled €55.6 million. It has enabled higher education institutions (HEIs) across the island to deepen partnerships, to leverage new collaborative relationships in research and to build research capacity on an all-island basis. The Insights on Impact publication has been coordinated by the HEA in partnership with the All-Island Research Excellence Network (AIREN). It draws its findings from interviews carried out by Dr Claire O’Connell with lead investigators from NSRP projects.
