Book excerpt: This book reviews the frameworks and implementation of marine, fishery and coastal laws and policies in Chile, Mexico and Peru. Chile, Mexico and Peru share biodiverse coastal and marine environments which are being affected by unregulated and informal developments, and thus share similar challenges. Each country is currently at a different stage of advancement in their institutional response to these complex challenges. By providing a comparison of the frameworks, approaches and overall implementation of policies and laws, this book acts as a tool to influence and inform further efforts in conservation and sustainable use of marine resources, particularly fisheries, in these countries and others in Latin America and the Caribbean. A broad range of issues are covered including food security, tourism, fisheries, oil and mineral extraction from the seabed, wind power, coastal and marine pollution and endangered species conservation. The chapters compare how each country addresses these issues from an institutional, legal and policy perspective. The book concludes by identifying common lessons, reoccurring challenges and develops scalable recommendations applicable to the case study countries and the wider region. The book will be of interest to advanced students, policy makers and researchers in marine and fishery science, law and policy.
