This chapter focuses on the communication strategies used by development agencies and partners in the development and implementation of sustainable development programmes, evaluating the impact these strategies have on health development and poverty alleviation in communities in Rivers State. Referencing the development media theory, the democratic participant theory and the communication for social change theory, the chapter examines four development agencies and partners; the Niger Delta Development Commission, The World Bank, The World Health Organization and Indorama Eleme Petrochemical Limited. The qualitative study design used (un-structured) in-depth interviews with staff from the organisations studied, and focus group discussion sessions were held with community dwellers in four local government areas. Findings showed that development agencies and partners used a variety of communication strategies, tools, and methods to communicate development initiatives.
