This collection features six peer-reviewed reviews on the economics of key agricultural practices. The first chapter assesses the economic impact of horticultural crops and integrated pest management programmes. The chapter highlights the importance of considering agricultural system design and the utilisation of novel control tactics. The second chapter considers the economic consequences of novel integrated weed management (IWM) strategies, as well as the different approaches used to assess the economics of IWM strategies. The third chapter reviews developments in methods to assess the economic value of agricultural biodiversity. The chapter also outlines the limitations of these methods and proposes a possible, novel way forward. The fourth chapter provides an overview of the economic barriers faced by smallholder farmers, including land, labour, capital and inputs, and their impact on farm profitability. The fifth chapter reviews the economics of soil health, focussing on the adoption of soil health management practices by farmers and the effectiveness of incentives. The final chapter examines the use of economic research as a tool to determine the profitability and adoption potential for a number of precision agriculture technologies.

"The sustainable intensification of smallholder farming systems is a standard reference on how best to target support for smallholders to achieve real improvements in their livelihoods." (IITA - Cassava Matters) Due to a lack of understanding of the constraints they face, many projects developed to support smallholders fail with low adoption rates and limited improvements in livelihoods and food security. Greater emphasis must be placed upon successfully supporting smallholder farmers and their farming systems. The sustainable intensification of smallholder farming systems provides a comprehensive review of recent research on effective support measures to improve the livelihoods of smallholders in sub-Saharan Africa. This collection features detailed discussions on ways to improve access to key resources, such as seeds, tools and expertise for soil health improvement and integrated pest management (IPM) programmes. A part dedicated to finance and information assesses the need to improve support systems, including farmer organisations and commercial extension services, for the benefit of particular groups of smallholders, e.g. female farmers. Based on a wealth of practical experience from leading experts in the field, The sustainable intensification of smallholder farming systems will be a standard reference on how best to target support for smallholders to achieve real improvements in their livelihoods. It will be essential reading for university and other researchers studying smallholder farming systems in departments of agricultural science, international development, politics and development economics. It will also be a key reference for government and non-governmental organisations (NGOs) involved in development programmes focussing on smallholders, particularly in sub-Saharan Africa.
