Several years ago LLC had the opportunity to evaluate the Mesoamerican Reef Leadership Program (MAR-L). It was an important evaluation that laid some groundwork for a research project we initiated the following year to explore the topic of ‘Leadership and Large Scale Change.’ We were inspired by MAR-L. MAR-L set itself apart from many other leadership programs because they were not content to simply focus on building the leadership capacity of young entrepreneurial conservation leaders, which itself would have been an important endeavor. They were also willing to ask tough questions about whether the investment in young people and their projects was making a difference in the health of the reef. Ultimately, most leadership programs are serving some larger purpose, and because of the challenges of understanding the contributions of their leadership development work to larger scale changes, most programs focus primarily on the ways in which participants of programs believe they have benefited. This is starting to change, and we are excited to be part of evaluating programs that tell a different story about the ways in which leadership development programs are supporting changes in the lives of people, and the planet.
