Ghana's decentralisation system seeks to foster local peace, security and development through participatory development planning and administration. However, participation in this regard has been questioned. This study sets out to investigate how participatory planning has promoted (or threatened) peace, security and development since 1996 in the Kwahu North District in the Eastern Region. What are the existing measures and structures for ensuring that some communities do not impose their preferences on others? A preliminary research in the district indicates that some major towns and communities are bitter because of perception of neglect in the distribution of development projects in favour of others. Primary data for this study will be collected from members of Area/Town Councils and District Planning Coordinating Units through interviews and focused group discussions. These local structures are in charge of district planning and thus have adequate knowledge on participatory processes and their impact(s) on communities and their well-being.
