Book excerpt: Whereas there is plenty of work looking at macroeconomic effect of public spending on growth and poverty in Africa as well as studies of the impact of spending or investment in one economic sector on outcomes in that sector or on broader welfare measures, this book fills a much needed gap in the research looking how the composition of public spending affects key development outcomes in the region. The book brings together recent analysis on the trends in, and returns to, public spending for agricultural growth and rural development in Africa. Case studies of selected African countries provide insights on the contributions of different types of public expenditures for poverty, growth and welfare outcomes, as well as insights into the constraints in gaining development mileage from investments in the agricultural sector.
