Impacts of Climate Change

Coastal Zones

This information should guide UNDP Programme Officers in preparing adaptation-relation projects that address climate change impacts on coastal zones. The following information is contained:
  • Overview of the linkage between climate change and coastal regions;

  • A figure illustrating the distribution of impacts on coastal zones;

  • An example of a relevant project document and/or ongoing adaptation-related project;

  • Links to additional information on climate change and coastal zone vunerability.


The figure above, based on research by Dilley et al (2005), shows cyclone mortality risks. Coastal regions in red face the highest risk of significant impacts, while coastal areas in blue have the lowest hazard risk.

Overview

Coastal erosion, already a problem due to maladaptive practices in many regions, is likely to be exacerbated by climate change (specifically by increase in sea level and frequency of storm surges). Expected impacts include:

  • inundation of coastal regions and other lowlands;

  • shoreline erosion and impacts on coastal infrastructure;

  • threatened livelihoods in agriculture, tourism, infrastructure and other key sectors.

Not all regions will be similarly affected - some regions will be more vulnerable than others.

Adaptation projects should focus on reducing vulnerability and/or increasing adaptive capacity of communities and/or ecosytems to climate change (including variability) in coastal zones. Projects are expected to encompass a suite of adaptation measures including piloting measures, institutional strengthening and/or capacity building. Projects should include at least two of the above three elements.

UNDP Programme Officers are encouraged to draw on the latest scientific findings on the vulnerability of coastal zones to climate change when formulating adaptation projects. The "Relevant Links" section below provides some starting points for additional information.

Funding for Adaptation Projects

Adaptation-related projects that address climate change impacts on coastal zones are potentially eligible under any of the currently active funds. LDCs, with projects focusing on short-term adaptation strategies, must submit proposals under the LDCF. Projects that focus on long-term adaptation measures must be submitted under the SCCF (please note: for non-LDCs, adaptation projects with short-term measures are not eligible for funding under any adaptation fund as they should be covered by baseline activities). Projects submitted under the SPA are required to demonstrate global environmental benefits in an appropriate focal area.
