A global analysis of erosion of sandy beaches and sea-level rise: An application of DIVA

This paper presents a first assessment of the global effects of climate-induced sea-level rise on the erosion of sandy beaches, and its consequent impacts in the formof land loss and forced migration of people.We consider direct erosion on open sandy coasts and indirect erosion near selected tidal inlets and estuaries.

Adaptation and Mitigation in Long-term Climate Policy

The paper analytically explores the optimal allocation of investments into mitigation and environmental adaptation against climate change damages at a macroeconomic level. The economic-environmental model is formulated as a social planner problem where adaptation and abatement investments are separate decision variables.

The double trade-off between adaptation and mitigation for sea level rise: an application of FUND.

This paper studies the effects of adaptation and mitigation on the impacts of sea level rise. Without adaptation, the impact of sea level rise would be substantial, almost wiping out entire countries by 2100, although the globally aggregate effect is much smaller. Adaptation would reduce potential impacts by a factor 10–100.

Impacts and responses to sea-level rise: a global analysis of the SRES scenarios over the twenty-first century.

Taking the Special Report on Emission Scenarios (SRES) climate and socio-economic scenarios (A1FI, A2, B1 and B2 ‘future worlds’), the potential impacts of sea-level rise through the twenty-first century are explored using complementary impact and economic analysis methods at the global scale. These methods have never been explored together previously.

Sea-level rise impact models and environmental conservation: A review of models and their applications.

Conservation managers and policy makers need tools to identify coastal habitats and human communities that are vulnerable to sea-level rise. Coastal impact models can help determine the vulnerability of areas and populations to changes in sea level. Model outputs may be used to guide decisions about the location and design of future protected areas and development, and to prioritize adaptation of existing protected area investments.

Coastal flood damage and adaptation costs under 21st century sea-level rise.

Coastal flood damage and adaptation costs under 21st century sea-level rise are assessed on a global scale taking into account a wide range of uncertainties in continental topography data, population data, protection strategies, socioeconomic development and sea-level rise.

Integrating knowledge to assess coastal vulnerability to sea-level rise: The development of the DIVA tool.

This paper describes the development of the DIVA tool, a user-friendly tool for assessing coastal vulnerability from subnational to global levels. The development involved the two major challenges of integrating knowledge in the form of data, scenarios and models from various natural, social and engineering science disciplines and making this integrated knowledge accessible to a broad community of end-users.

Protection versus retreat: the economic costs of sea-level rise.

This paper analyses the relative role of protection and mitigation expenditures within the total costs of climate change induced sea level rise. It derives a rule of thumb to approximate the optimal level of protection. Economic efficiency requires that protection expenditures are designed such that the sum of protection costs plus remaining land loss damage is minimised. A formula is derived according to which the optimal protection level depends on the relative importance of dryland loss compared to the costs of accelerated wetland loss plus protection expenditures.

Coastal Zones and Small Islands.

As part of the IPPC report the report describes the impacts of climate change for coastal areas and small islands. Furthermore, it discusses adaptation reponses.

Reducing Extreme Weather Event Impacts

This report focuses on identifying criteria, indicators and policy options for managing climate variability and change (extreme events). It also discusses critical issues for the assessing policies aimed at managing extreme weather event.
