Productivity for Prosperity (P4P) Productivity for Prosperity is a sustainable economic transformation programme that will increase labour productivity and climate-resilience in Tanzania’s job-creating sectors. It will achieve this through private sector development (investment facilitation, trade facilitation and building capabilities of firms) and business environment reform (supporting proportionate and predictable regulation). P4P will dovetail with the UK’s external engagement and influencing activities in Tanzania. P4P will initially prioritise the agroprocessing and horticulture sectors, and will provide flexible support to bolster the UK’s current and future prosperity objectives.
