Natural and industrial disasters are major risks with the common specificity of a strong geographic dimension. Their main difference is that compensation for natural disasters relies on solidarity, whereas industrial risks imply the liability of the industrialist. This thesis brings parts of assessment of prevention and coverage policies for natural and industrial risks. Each chapter provides some elements of policies assessment and analyzes in particular links between insurance and urbanism policies (Chapter 2), between insurance and collective prevention policies (Chapter 3), between insurance and assistance policies (Chapter 4), between prevention policies and real estate market (Chapter 5). Interaction between national and local public policies is addressed in each chapter.
