The sector now employs more than half of the labor force but produced only 15% of GDP continent-wide, with considerable cross-country variation, indicat- ing that current performance remains below potential. Building a resilient and sustainable agriculture in Sub-Saharan Africa contains technically rich and policy-relevant chapters that shed light on the performance and chal- lenges of Africa’s agriculture sector, particularly, climate shocks exposure due to an over-reliance on rain-fed agriculture combined with low invest- ment levels. This book offers an excellent contribution for better understanding of the current state and prospects of Africa’s agricultural transformation and generates valuable insights for improved agricultural policymaking on the continent. Beyond the collection of and reflection on African stories, this compilation interestingly proposes pragmatic policy options for improving agriculture productivity, mitigating climate shocks exposure and promoting agro-industrialization. As advocated by the authors, these three targets are key to unleashing Africa’s agriculture potential. It is now time for Africa to feed Africa … and the rest of the world. And achieving this goal will require synergetic actions between governments, v vi Foreword private sector or other stakeholders. The current collection of analytical chapters from African researchers is an excellent contribution to that col- lective effort. Cornell University Christopher B. Barrett, Ithaca, NY, USA December 2017 Acknowledgments This book brings together a selection of chapters presented at the 2016 African Economic Conference (AEC) in Abuja, Nigeria, under the theme: “Feed Africa: Towards Agro-Allied Industrialization for Inclusive Growth”. The chapters have been selected by experts in agriculture at Cornell University and then enriched by valuable comments by peer reviewers, discussants and rapporteurs at the conference. Our appreciation goes to Charlotte Karagueuzian for excellent research assistance and coordination with the authors and to the African Development Bank Language Services Department for translating some of the chapters from French to English. The AEC 2016 provided a unique opportunity for policymakers and researchers, including the diaspora, to interact and debate the critical policy issues affecting Africa. This conference would not have been pos- sible without the full support and the leadership of the African Development Bank’s President, the Executive Secretary of the Economic Commission for Africa and the Administrator of the United Nations Development Programme. Many staff members of these institutions ded- icated their time and energy in making the conference a success. Their contributions are deeply appreciated. We are extremely grateful to the researchers who presented their papers at the AEC 2016 for their high-quality contribution. This publication aims at stimulating debate and shaping policy recommendations around the resilience and sustainability of agriculture in sub-Saharan Africa. vii Contents 1 Introduction: Understanding the Challenges of the Agricultural Sector in Sub-Saharan Africa 1 Abebe Shimeles, Audrey Verdier-Chouchane, and Amadou Boly Part I Improving Agricultural Productivity 13 2 Improved Seeds and Agricultural Productivity of Family Farms in Cameroon 15 Christelle Tchamou Meughoyi 3 Breaking the Traditional Trap: Assessing Drivers of Modern Technology Adoption by Smallholder Farmers in Hurungwe District, Zimbabwe 33 Carren Pindiriri 4 Input Utilization and Agricultural Labor Productivity: A Gender Analysis 55 A.
