26 January 2017 - Inclusive and just governance at societal levels, and of ocean resources, and the establishment of partnerships including those with governments, the business sector and representatives of stakeholder and civil society groups.

This 30 million square km of ocean off the coasts of ten east and southern African countries supports some 60 million people living within 100km of the shore.

The annual economic output of the ocean is estimated to come fourth in line behind the region’s biggest economies – South Africa, Kenya and Tanzania. It produces more than $20.8-billion in goods and services every year.

But the health of the ocean is approaching a turning point. Many principal ocean assets are declining as a result of exploitation. And this is happening at a time when the use of ocean resources to support growth is accelerating.

So a key question is: can the ocean economy in the Western Indian Ocean grow and support those countries’ aspirations in coming decades?

Remarkable and sobering findings, and possible answers, are contained in a new report. It was led by the World Wildlife Fund, the Boston Consulting Group and CORDIO (Coastal Oceans Research and Development in the Indian Ocean East Africa) East Africa.

Ocean asset base

The economic analysis focused on ocean goods and services that were based on living marine ecosystems. It didn’t include activities like shipping and mining that don’t depend on ecological functions of the sea. The researchers found the region’s total ocean asset base, a sort of “shared wealth fund”, was at least $333.8-billion.

The main assets include fisheries, the coastline itself, mangroves, carbon absorption, seagrass beds and corals reefs. The most productive benefits annually are from coastal and marine tourism, carbon sequestration and fisheries.

But the health of the assets that provide these benefits is in jeopardy. The report documents that 35 percent of the fish stocks assessed in the Western Indian Ocean are fully exploited and 28 percent are over-exploited. Over the course of 25 years, both Tanzania and Kenya lost 18 percent of their mangroves. Over 50 percent of the shark species assessed in the region are considered threatened. And 71-100 percent of the region’s coral reefs are at risk, with the exception of those in the Seychelles.

Beyond pure economics, the social importance of the ocean economy must be considered. For example, statistics used in the report tell us that industrial fisheries in the region produce more than six times the revenue of small scale fisheries. Yet small scale fisheries support over 250,000 fishers across the ten countries – and up to a half a million by other estimates.

Beyond these direct users, fisheries also support fish traders, equipment suppliers and others involved in the sector, and all their dependants. Fish provide a significant part of household protein intake in some coastal communities living in poverty. Many such food and livelihood benefits are not captured even in this novel approach to economic analysis.

Ocean-led development

The current declines in ocean assets, and future population and economic growth, provide a profound challenge to the Blue Economy’s future. This is at the core of the African Union and individual countries’ aspirations for development led by the ocean.

The world is focusing on the Sustainable Development Goals (SDGs) and the United Nations’Agenda 2030. This new report’s focus is on the importance of the 14th goal: “to conserve and sustainably use the oceans, seas and marine resources”.

In its concluding section it identifies seven actions, each linked to an SDG. A few things are core to the success of ocean-led development: inclusive and just governance at societal levels, and of ocean resources, and the establishment of partnerships including those with governments, the business sector and representatives of stakeholder and civil society groups.
