This Think Tank will provide an overview of the Blue Marble Evaluation perspective, examples of how evaluators have applied the principles across different sectors (e.g., public health, climate, education), and give participants an opportunity to discuss how they can use the approach in their work. Breakout groups will focus on understanding how this perspective and accompanying principles can be applied in day-to-day evaluative inquiry. We will then come together to share ideas on how to carry this approach forward and spark a movement of more Blue Marble thinkers.
