Legal requirements for risk and vulnerability assessments in Norwegian land-use planning

Abstract

Land-use planning has been promoted as an important tool for adaptation to climate change. However, its success depends on effective communication between researchers and decision-makers. A “risk and vulnerability assessment” (RVA) is one method to facilitate the interaction between the groups. RVAs have been performed in Norwegian land-use planning for about 20 years, and been mandatory for new development the last few years. The first part of the article reviews the history and current legal regulation of RVAs in Norway. Continuing, the main part discusses the distribution of authority and responsibility for different parts of the process and result. The key finding is that significant decisions are deferred to municipal discretion, for example, the necessity (if doubtful) and scope of the assessments. Other topics (such as the burden of costs and eligible performers) are largely unregulated, prompting some arguments about the need for further legislative effort.
