Invited Speakers

Mr Alasdair Davies

Alasdair Davies is Technical Director of the Arribada Initiative C.I.C., founded in 2018 to increase access to open-source conservation technologies. Alasdair has 20 years of experience developing, designing, and deploying conservation technologies for organisations worldwide. His primary focus is the development of low-cost telemetry and biologging devices. He tagged his first green turtle on the shores of Príncipe Island, West Africa, in 2014 and has never looked back.

Over the past decade, Alasdair has dedicated himself to the design and development of an open-source satellite sea turtle tag, with the goal of reducing barriers to access for engineers and researchers seeking to develop biologging instruments for sea turtle conservation.

Dr Judy Mann-Lang

After more than 30 years at the intersection of conservation, management, and communication, Judy’s work now centres on two areas: inspiring care for the ocean and strengthening the confidence, skills, and impact of conservation communicators.

Judy spent three decades at SAAMBR, serving as Director of Education, uShaka Sea World Director, and its first female CEO, followed by five years with the Two Oceans Aquarium Foundation. She holds a PhD from the University of Queensland, and her research now focuses on monitoring and evaluation, conservation learning, behaviour change, and ocean literacy.

She runs workshops on conservation communication, science communication, evaluation, and behaviour change, and has designed and delivered hundreds of training courses for diverse audiences, from marine educators and law enforcement officials to subsistence fishers, marine protected area managers, field guides, scientists, and conservation practitioners. Her work is grounded in a deep understanding of both people and the natural world.

Judy co-founded the South African Marine and Coastal Educators Network and initiated Marine Protected Areas Day and the African Penguin Not On Our Watch campaign. Fascinated by human behaviour and continually inspired by time spent in nature, she is now focused on supporting the next generation of passionate and effective educators and conservationists.
