Context and Key Issues

Tuna is the most important resource exploited in the Indian Ocean, both in terms of volume and value. The sector accounts for 20% of global tuna landings and a landed value of around 2 billion USD.

However, the economic, social, and environmental sustainability of this sector is increasingly compromised, in particular by:

  • Growing tensions between regional and “extra-regional” interests, leading to inequalities in the redistribution of the added value generated by tuna fishing at different levels of the supply chain;

  • Growing pressure on certain stocks, particularly due to an increase in demand and major technological advance in fishing gear and techniques;

  • A lack of governance, including a paucity of data regarding certain fleets, the absence of a quota system, and difficulties in combating illegal, unreported and unregulated fishing.

In this context, IDDRI has been conducting a project aimed at identifying and promoting ways to put the Indian Ocean tuna industry back on the road to more sustainable management.
