Agulhas undertook an evaluation of the British High Commission in Tanzania’s work on sustainable growth and investment partnerships from 2020-2025.
We evaluated the UK government’s ‘whole of government partnerships’ approach to development in Tanzania, including partnerships across the UK government and with the Tanzanian government and private sector. This covered the full range of levers available to the UK, including development funding, commercial and trading relationships, policy and diplomatic engagement and UK loan and financing facilities and expertise.
The purpose of the evaluation was to identify opportunities to help strengthen the UK’s approach to sustainable growth and investment in Tanzania and more effectively plan, implement, monitor and evaluate the ‘whole of government partnerships’ approach to development. We also helped the FCDO develop methods to evaluate ‘whole of government partnerships’ approaches more widely.
Our evaluation approach was comprehensive, rigorous and participatory. We conducted a process evaluation and theory-based design, applying outcome harvesting. The evaluation questions covered effectiveness, coherence and learning, as well as cross-cutting objectives.
The evaluation took place in 2025, prior to the October 2025 elections, and included consultations in Tanzania, culminating in an evaluation report and tailored knowledge and learning products and dissemination activities.
We worked with a highly experienced team of Agulhas staff and experts, including Johanna Polvi (Team Leader), Liz Turner (Project Director), Agatha Nderitu (Senior Expert), Gordon Freer (Senior Evaluation Methods Expert) and Olivia McConnell (Senior Analyst). We also partnered with The Canopy Lab (Tim Sparkman, Senior Methods Evaluation Expert), a small consultancy focused on the application of systems thinking, providing strategic consulting, research and evaluations.
