WIO Symphony – a tool for ecosystem-based marine spatial planning

Find on the page

WIO Symphony is a web tool that supports marine spatial planning in the Western Indian Ocean by assessing environmental impact from human activities. We develop the tool together – the Nairobi Convention, its ten member states and a Swedish team.

Show, calculate, compare

The WIO Symphony web tool supports your marine spatial planning by assessing environmental impact from human activities. WIO Symphony lets you visualize data, test scenarios, and compare different ways of using the ocean.

  • Show data
  • Create maps
  • Calculate cumulative impact on environment
  • Compare planning options

The user interface gives you control of your work.

Cumulative impact is shown as heat maps, too.

How WIO Symphony works

illustration av WIO Symphony method.

The WIO Symphony web tool supports your marine spatial planning by assessing environmental impact from human activities. Pressures, ecosystems and sensitivity are combined into cumulative environmental impact. Click to enlarge.

WIO Symphony is based on more than 80 maps of ecology and human activity. The tool combines pressures, ecosystems and sensitivity into cumulative environmental impact.

The results are presented as heat maps, which makes it easy to identify areas of high and low cumulative impact.They are also presented as tables and diagrams showing details for any given area. Uncertainties are highlighted too.

A similar tool was developed and used in Swedish marine spatial planning.

Developed for the Western Indian Ocean

The WIO Symphony project is a collaboration between the Nairobi Convention, its ten member states in East Africa and a team of Swedish institutions lead by the Swedish Agency for Marine and Water Management.

Together we co-develop the WIO Symphony tool for the Western Indian Ocean.

The tool is hosted in the region, available to practitioners there.

The partnership

The Nairobi Convention secretariat - ensures regional representation and links to policy

The ten member states

  • Somalia
  • Kenya
  • Tanzania
  • Mozambique
  • South Africa
  • Comoros
  • Madagascar
  • Seychelles
  • Mauritius
  • Réunion, France.

Each state has a representative in the technical working group to tailor WIO Symphony to their user needs.

Swedish Agency for Marine and Water Management (SwAM) - leads the Swedish team


Geological Survey of Sweden (SGU) - contributes with expert knowledge on marine geology, as well as technical and analytical expertise


Swedish University of Agricultural Sciences (SLU) -collects and processes relevant data


University of Gothenburg (GU) - provides expert knowledge on deep sea ecology and oceanography


We consult additional experts from universities, institutions, and governments along the way.

The Symphony tool for the Western Indian Ocean

The WIO Symphony tool for the Western Indian Ocean covers 9 percent of the world ocean. The WIO Symphony project is a collaboration between the Nairobi Convention, its ten member states in East Africa and a Swedish team.

Data contributors

The development of WIO Symphony was possible also thanks to all data contributors – thank you! See the list at www.nairobiconvention.org/wio-symphony.
