The objective of this manual is to raise awareness of the existing opportunities and avenues for the public to engage throughout the national budget cycle of Kenya as well as provide an overview of the principles underlying participatory budgeting and further outline best practices in participatory budgeting. It is expected that cumulatively through this manual civil society and generally public participation in the budget making processes would increase and the degree of inclusivity in decision making processes enhanced. Ultimately civil society members and local citizens would be well equipped with information and knowledge to be able to fully participate in budget making and be able to meaningfully influence public service delivery, planning and allocation of public resources. Additionally, it is assumed that CSOs representatives who participate in training on this manual would in turn pass on the skills and knowledge so gained to empower their constituents and the ripple effect is expected to bear inclusitivity in budgeting practices.
