Dr Richard Caddell is a Reader in Marine and Environmental Law at Cardiff School of Law and Politics, co-director of the Centre for Environmental Law and Policy and a member of the Wales Governance Centre. Richard was previously a Senior Research Associate and Nippon Foundation Senior Nereus Fellow at the Netherlands Institute for the Law of the Sea, Utrecht University and has also held academic positions at the Universities of Swansea and Bangor. He was educated at Cardiff University, completing a PhD on the conservation of marine mammals in 2009. 

Richard's primary research interests lie in the law of the sea and environmental law, with a particular emphasis on wildlife conservation law, fisheries management, marine mammals, Polar law and marine environmental law at the international, EU, UK and devolved levels, as well as the exercise of free speech and protest rights. He is a Principal Investigator within the Nippon Foundation's Ocean Nexus Center, leading a project on ‘Brexit, Devolution and the Sea: Recasting Marine Governance in UK Waters’, which examines marine regulation by the devolved administrations and the ongoing impacts of Brexit on the marine environment of the UK. Richard is also a technical advisor with Conservation Without Borders, the leading conservation organisation promoting the protection of migratory wildlife.

Richard is currently writing Migratory Species and International Law: Challenges of Transboundary Conservation, the first major work on the legal issues raised by migratory wildlife, which will be published in 2024 by Edward Elgar. He is the co-editor of Research Handbook on Climate Change and Biodiversity Law (Edward Elgar, 2024, with Phillipa McCormack), Wetlands and International Environmental Law: The Evolution and Impact of the Ramsar Convention (Edward Elgar, 2024, with Royal C. Gardner and Erin Okuno), Strengthening International Fisheries Law in an Era of Changing Oceans (Hart, 2019, with Erik J. Molenaar), Shipping, Law and the Marine Environment in the Twenty-First Century (Lawtext, 2013, with D. Rhidian Thomas) and four editions of Blackstone's Statutes on Media Law (Oxford University Press, 2006, 2008, 2010, 2013, with Howard Johnson). Richard is the Editor-in-Chief of the Journal of International Wildlife Law and Policy, serves on the Editorial Boards of the Yearbook of International Environmental Law, the Review of European, Comparative and International Environmental Law and Communications Law and is co-editor (with Malgosia Fitzmaurice and Agnes Rydberg) of Edward Elgar's forthcoming series of books on Principles of International Environmental Law.

My research interests lie predominantly in the Law of the Sea and Environmental Law, with a particular interest in biodiversity law, natural resources, ecosystem management and legal issues of climate change. I have a particular interest in willdife conservation law, especially concerning migratory species, marine mammals and fisheries, as well as the protection of particular habitats, notably wetlands, mountain ecosystems and ice-covered areas. I am the Editor-in-Chief of the Journal of International Wildlife Law and Policy and have written and consulted extensively on wildlife law and marine environmental protection.

I am currently leading a research project entitled 'Brexit, Devolution and the Sea', funded under the Nippon Foundation's Ocean Nexus Center, where I am investigating the protection of marine ecosystems and species by the devolved administrations in the context of the repatriation of powers as a result of the Brexit process. In particular, I am currently researching issues related to marine plastic, especially in Wales, which has been cited in the House of Lords' debate on the Environment Bill ( More broadly I am currently finalising the first major book on the international protection of migratory species and the legal issues raised by transfrontier wildlife conservation.
