Oxfam's Trustees

Oxfam's Trustees form the Council of Trustees, which is the governing body of the Association of Oxfam (a not-for-profit limited-liability company). 

They are appointed because of their commitment to Oxfam and their experience and skills which enable them to undertake the responsibilities of trusteeship of a large and complex charity. 

Reports on council meetings can be found on the plans, reports and policies pages.

Nana Afadzinu, Interim Co-Chair

Nana was called to the Ghana Bar in 1996, intending to enter private legal practice, but discovered her passion for social justice as a Legal Officer with the African Commission for Human and Peoples' Rights in the Gambia. This was at the height of Sani Abacha’s excesses, and several civil society organisations engaged the Commission and fought for democracy and the protection of human rights in their countries. She has not looked back since.

In 2004, Nana coordinated the work of the 200-member-plus coalition advocating for a legal framework to protect survivors of domestic violence in Ghana and remains active in the women's movement.

At the Open Society Initiative for West Africa (OSIWA), Nana pushed for an enabling environment for civic engagement, consolidating democracy, transparency and accountability in governance, and the respect, promotion, protection and fulfilment of human rights across the region.

As Regional Policy Advisor for Ibis West Africa, she contributed to improving natural resource governance, local governance and education in Ghana, Sierra Leone and Liberia.

Nana now leads the West Africa Civil Society Institute (WACSI), which works to strengthen the capacity of civil society primarily in West Africa to become more effective, efficient and sustainable in the fight for social justice and contribution to development. Nana is Interim Co-Chair alongside Annie Hudson.
