The Journey from Istanbul: Evidences on the implementation of the CSO DE Principles is a compilation of stories of good practices, challenges faced and gaps identified in the implementation of the Istanbul Principles in different country contexts. The case stories are from 19 organizations from 17 countries spanning the different global regions. This is the first attempt of the CPDE Working Group on CSO Development Effectiveness to document such initiatives in strengthening CSO work in promoting their own effectiveness. This document, together with the first Global Training of Trainers on CSO DE held in Johannesburg, South Africa in 2013, are evidences demonstrating CSOs contribution to the Principles articulated in the Busan Partnership Document, despite difficult socio-political, economic and cultural situation in the countries and communities they work in. Initiatives such as these are proofs that a shrinking space and other challenges do not and will not deter CSOs from persevering – from service delivery to advocacy – in serving the people.
