Climate change threatens small-scale aquaculture in Southeast Africa, with unpredictable rainfall, extreme weather events, and rising temperatures disrupting water availability, fish health, and farm productivity. Without targeted adaptation, entire aquaculture cycles risk failure – undermining livelihoods, nutrition, and rural resilience.

This paper is for practitioners, researchers, and development partners seeking actionable, cost-effective strategies to safeguard aquaculture from climate impacts. It provides a step-by-step approach, from assessing regional vulnerabilities to piloting and scaling solutions such as intermittent harvests, climate-resilient infrastructure, and digital weather alerts.

By integrating technical innovation with community-based adaptation, the document offers a practical toolkit to strengthen climate resilience across the fish value chain, supporting long-term sustainability and food security in vulnerable regions.

About the Programme

By 2050, the world’s population is expected to reach nine billion people, resulting in increased demand for food and jobs. Thanks to the nutrients they contain, fish products are a means of combating undernourishment and malnutrition. They help to secure the livelihoods of millions of families. However, illegal, unreported and unregulated (IUU) fishing is depleting fish catches and contributing to economic losses. There is a lack of legal framework conditions, access to high-quality resources such as feed and technical knowledge regarding sustainable fish production and processing.

Objective

The population facing food insecurity has access to more fish products and higher incomes derived from sustainable and resource-friendly fisheries and aquaculture.

Approach

‘More fish, more work’: the project advises small and medium-sized businesses on sustainable fish production and processing. This creates jobs and income-generating opportunities in the value chain. Innovative production methods cut costs and reduce after-catch losses.

‘Sustainable fish’: the project also advises the governments in its partner countries on planning and implementing strategies, action plans and other measures. In this way, it contributes to providing the necessary framework conditions for resource-friendly, artisanal fishing and aquaculture.

‘Less fish from IUU fishing’: IUU fishing is to be curbed by introducing registration and licensing systems for fishers and their boats and by conducting inspections.

The European Union supported the project until September 2022 with a cofinancing arrangement to develop and implement hygiene standards in the fish value chain in Mauritania.

In addition, the project cooperated until March 2022 with the non-governmental organisation Stop Illegal Fishing to support partner countries in implementing the Agreement on Port State Measures (PSMA) of the Food and Agriculture Organization of the United Nations.
