Compendium on methods and tools to evaluate impacts of, and vulnerability and adaptation to, climate change


Dynamic Interactive Vulnerability Assessment (DIVA) is a tool for integrated assessment of coastal zones produced by the EU-funded DINAS-Coast consortium in 2004.

It is specifically designed to explore the vulnerability of coastal areas to sea-level rise. It comprises a global database of natural system and socioeconomic factors, relevant scenarios, a set of impact-adaptation algorithms and a customized graphical-user interface. Factors that are considered include erosion, flooding salinisation and wetland loss.

DIVA is inspired by the paper-based Global Vulnerability Assessment (Hoozemans et al., 1993), but it represents a fundamental improvement in terms of data, factors considered (which include adaptation) and use of PC technology.

Appropriate Use DIVA is designed for national, regional and global scale analysis of coastal vulnerability, including consideration of broad adaptation issues.
Scale DIVA covers all 180+ coastal nations in 12,148 coastal segments at national, regional, and global scales.
Key Output The impacts of sea-level rise under a range of different user-defined scenarios, including some adaptation options. For each SRES the program produces a table, a map and chart.
Key Input The user’s chosen scenarios.
Ease of Use The software is explicitly intended to be easy to use, and draws on extensive experience in graphical user interfaces.
Training Required Designed to be used without significant training, an interested user should be able to explore this tool without any training.
Training Available If required, contact DINAS-COAST consortium, see contacts.
Computer Requirements Windows 2000/XP, 2 GHz Pentium, 512 MB memory, 5 GB free hard drive.
Documentation Included with the DIVA tool.
International studies

DIVA has been used to develop assessments of wetland loss and the effects of mitigation. Examples of studies are;
Hoozemans et al. (1993), Nicholls (2002), Hinkel and Klein. (2003), Vafeidis et al. (2003, 2004a, 2004b).
