"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.
