Impacts of Climate Change

International Waters

This information should guide UNDP Programme Officers in preparing adaptation-related projects that address climate change impacts in the international waters focal area. The following information is contained:

  • Overview of the linkage between climate change and international waters;

  • A map illustrating regions where impacts on international waters due to climate change are a pressing issue;

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

  • Links to additional information on climate change and international waters.


The above map shows the effects of 14-year cumulative sea surface temperature anomalies and areas of coral bleaching (denoted by red circles). The yellow coloured areas indicate temperatures 1°C above the mean and orange regions indicate anomalies 2°C above the long-term average.

Overview

Projected impacts on transboundary water resources due to climate change and climate variability include:

  • hydrologic changes, including changes in the timing of streamflow that result in downstream effects;

  • reduction in the quality and availability of water supplies;

  • potential for increased competition of water resources in transboundary basins;

  • acceleration of the retreat and loss of glaciers;

  • spread of invasive species and bleeching of coral reefs;

  • changes in fisheries habitats;

  • intensified shoreline changes, such as coastal erosion.

Adaptation-related projects in the international waters focal area should focus on maintaining or strengthening the resilience of species and/or ecosystems threatened by climate change. Projects should reflect dynamic, long-term response measures.


Funding for Adaptation Projects

Adaptation projects in the international waters focal area should be submitted for funding under the Strategic Priority on Adaptation (SPA). Click here to be directed to the SPA guidelines.
