Citizen Science

Empowering Communities

Keynote addresses by Sam Johnson (Civic Entrepreneur) and Dr Xavier Pochon (Cawthron Institute).

Our 81st Annual Thomas Cawthron Memorial Lecture was held on Thursday 8 August, 2024.

As we tackle some of the most pressing issues of our time – climate change, biodiversity loss and food security – it is now more important than ever that we harness the collective efforts of engaged citizens to achieve more, and faster. Civic Entrepreneur Sam Johnson shared his experiences of engaging communities for social good, followed by Cawthron’s Dr Xavier Pochon who provided a comprehensive overview of how citizen science is contributing to mapping ocean health through the newly launched Citizens of the Sea project. Our speakers’ presentations highlighted the synergy between volunteer mobilisation and scientific research, demonstrating how collaborative efforts can lead to meaningful change.
