Lydia Stone

Lead Consultant - Security, Justice and Peacebuilding


Lydia joined Social Development Direct in 2014 and leads our work on Security, Justice and Peacebuilding. This portfolio has included programme management of SDDirect’s contribution to the Nigeria Stability and Reconciliation Programme, Access to Security and Justice Programme in Sierra Leone and the Access to Justice Programme in South Sudan, and team leading on the evaluation of the UK’s National Action Plan on Women, Peace and Security.

Prior to joining SDDirect Lydia lived and worked for several years as a freelance consultant in South Sudan where she undertook a range of assignments advising on security sector reform, community security, arms control, conflict sensitivity and gender. She served as an advisor to DFID and the Stabilisation Unit with regard to disarmament, demobilisation and reintegration, and worked as a Senior Advisor to the Ministry of Gender, Child and Social Welfare, including advising on the development of a National Action Plan on UN Security Council resolution 1325. She provided political economy analysis to the UK’s Security and Defence Transformation Programme and has published widely on issues of security and gender in South Sudan.

Lydia began her work in the field of international development as a researcher on the international arms trade, working on initiatives including the Control Arms campaign for an international Arms Trade Treaty and community security and arms control in post conflict contexts. In 2008-2009 Lydia undertook a 10-month assignment with Medecins Sans Frontieres in Nasir, South Sudan in a time of heightened local insecurity and it is this community that she often calls to mind when considering how and whether high level policies and initiatives are realistic and applicable at a local level.

Lydia has lived and worked across four continents, she speaks Spanish, and holds a Masters with Distinction in Conflict Resolution from the University of Bradford.
