The main aim of this project is to generate new knowledge about engaging teachers in a low-resource context with sustainability issues. The overall research question is ‘What is the meaning of Education for Sustainable Development (ESD) Continuing Professional Development (CPD) in a low-resource context?’ It will do so through an exploration of ESD CPD with teachers in the Horn of Africa. At present teachers in this region receive no CPD on ESD. This is in part an issue of low levels of teacher training and in general due to lack of resources. To the extent that teacher training exists in the region at present, it focuses only on general pedagogical skills and on the existing curriculum, which does not have an ESD component. It is also likely to be a part of a bigger picture of a generally low level of awareness of environmental and sustainability issues in the country.
