"It represents a truly magnum opus, contains copious references, and represents a distillation of the experience of scores of farmers, researchers and extension practitioners... To find such a wealth of practically-rooted experience on adoption and spread of Conservation Agriculture (CA) in this single Volume 3 of the series on CA is a triumph of hard work and wise collation which deserves widespread perusal by farmers and their organisations, researchers and policy-makers. At a time of such global challenge environmentally and in terms of ecosystem security, this book is timely indeed. May it achieve its aim to persuade and inform more adopters of CA." (Professor John Wibberley, Ag4Dev) "...this new volume is timely. More than 120 authors from more than 30 countries contribute global evidence and knowledge drawn together into a short survey and sixteen regional chapters, each including useful context and a section on where to look for further information...Our review of the first two volumes concluded: 'This book can change the future.' Chapters in this volume give us a glimpse of that future."(David Dent, International Journal of Environmental Studies) "The whole series is a magnificent achievement and will be the principal reference for years to come." (David Dent) With growing scientific concern around the limitations of tillage-based agriculture, coupled with the sector's need to contribute to being more sustainable, the development and adoption of alternative farming techniques has never been more important. Conservation Agriculture (CA) is emerging as a key alternative. The foundations of CA are built upon the use of no-till techniques and the use of rotations and cover crops to optimise different aspects of soil and crop health and resilience. Advances in Conservation Agriculture Volume 3: Adoption and Spread provides an authoritative review from an array of international experts on the adoption of CA principles in different regions around the world. The final volume in this collection reviews the effectiveness of CA in differing contexts (e.g. in drier conditions where water conservation is important or in areas with poor soil) and refers to the wealth of research and experiential evidence currently available.

"What Dr Samuel Johnson did for English, Professor Amir Kassam has done for Conservation Agriculture (CA). He is eminently well qualified and has enlisted more than a hundred battle-hardened champions to contribute 26 chapters amounting to over a thousand scholarly pages. The content is formidable. Volume one, Systems and Science, embraces: the need for CA; global developments; soil health and landscape management; the roles of minimum soil disturbance, mulch and cover crops; crops and cropping systems, vegetable systems, perennial systems; integration of cropping and livestock; mechanization; certification; institutional and policy support. Volume two, Practice and Benefits, includes management of crops and cropping systems, soil, weeds, insect pests and disease, nutrients, carbon, and biodiversity; climate change mitigation and adaptation; benefits to farmers and society; ecosystem services; and rehabilitation of degraded farmland...This book can change the future."review by David Dent in International Journal of Environmental Studies This volume summarises research on key components for successful Conservation Agriculture (CA). Chapters review the latest research on ways of optimising no-till techniques to minimise soil disturbance in relation to seeding, weeding and other operations. Chapters also review ways to improve soil health in CA, including mulch cover, cover crops, rotations and intercropping. The book also includes case studies on optimising CA in particular systems, including rice, root, tuber and horticultural crops as well as integrating livestock in CA systems. The book concludes by looking at certification schemes and institutional support to promote good CA practice.

Tillage agriculture has led to widespread soil and ecosystem degradation globally. This is especially so in Africa where traditional and modern tillage-based agricultural practices have become unsustainable due to severe disturbance and exploitation of natural resources, with negative impacts on the environment and rural livelihoods. In addition, agriculture in Africa today faces major challenges including increased costs of production and energy, the effects of climate change, and the lack of an effective paradigm for sustainable intensification, especially for small- and medium-size holdings. Africa is facing a serious challenge to food security and as a continent has not advanced towards eradicating hunger. In addition, the population is still growing much faster than on most other continents. This pressure has led to the emergence of no-till conservation agriculture as a serious alternative sustainable agriculture paradigm. In Africa, in recent years, conservation agriculture techniques and methods have spread to many countries, as greater development, education and research effort are directed towards its extension and uptake. This book is aimed at agricultural researchers and scientists, educationalists, and agricultural service providers, institutional leaders and policy makers working in the fields of sustainable agriculture and international development, and also at agroecologists, conservation scientists, and those working on ecosystem services. This book: * Focuses on research and development initiatives in Africa aimed at building resilient farming systems based on conservation agriculture principles and practices. * Summarises the status of conservation agriculture in Africa today and prospects for its future development in Africa as a basis for sustainable agriculture intensification. * Describes case studies showing the performance of conservation agriculture in Africa.

Tillage agriculture has led to widespread soil and ecosystem degradation globally, and more particularly in the developing regions. This is especially so in Africa where traditional agricultural practices have become unsustainable due to severe exploitation of natural resources with negative impacts on the environment and food system. In addition, agricultural land use in Africa today faces major challenges including increased costs, climate change and a need to transform to more sustainable production intensification systems. Conservation Agriculture has emerged as a major alternative sustainable climate smart agriculture approach in Africa and has spread to many African countries in the past decade as more development and research, including in sustainable mechanization, has enabled its extension and uptake. It is key to transforming Africa's agriculture and food system given its ability to restore soil health, biodiversity and productivity of millions of smallholder farms as well as larger-scale farms. This landmark volume is based on the material presented at the Second Africa Congress on Conservation Agriculture which was held in Johannesburg, South Africa, 9-12 October 2018. The main theme of the Congress was 'Making Climate Smart Agriculture Real in Africa with Conservation Agriculture: Supporting the Malabo Declaration and Agenda 2063'. The Congress was aligned to mobilize stakeholders in all agriculture sectors to provide greater technical, institutional, development and investment support, impetus and direction to the vision and agenda for transforming African agriculture as set out by the Malabo Declaration and Agenda 2063. This book is aimed at all agricultural stakeholders in the public, private and civil sectors in Africa engaged in supporting the transformation of conventional tillage agriculture to Conservation Agriculture. The book will be of interest to: researchers, academics, students, development stakeholders, public and private sector investors and policy makers as well as institutional libraries across the world.

The book covers the spread of conservation agriculture (CA) to regions including Brazil, Argentina, Canada, Australia, Europe and emerging CA destinations in Asia and Africa. Topics covered include the various components of CA, and how their individual and combined implementation influence productivity, soil health and environmental quality under diverse edaphic and climatic conditions. The book will be useful to teachers, researchers, extensionists, farmers, and students interested in environmental quality.

Chapters summarise research on optimising soil management, crop nutrition and irrigation, as well as weed, insect pest and disease management. The book also reviews ways of optimising the environmental and social benefits of adopting CA practices. Chapters discuss carbon and biodiversity management, the ways CA can promote ecosystem services as well as the use of life cycle assessment (LCA) techniques to monitor and improve CA. There are also chapters on improving the economic and broader social benefits of CA for farming communities.

This book analyzes the functions, content, methods, findings, and impacts of social and cultural research carried out by the worldwide network of 16 International Agricultural Research Centers of the CGIAR(Consultative Group on International Agricultural Research). Its two main parts - "insiders" and "outsiders" - bring together the perspectives of over 50 eminent scholars and social researchers from 30 countries, working within the Centers or within outside academic and development institutions. The authors examine critically the priorities, strengths, and weaknesses of research on the socio-structural, behavioral, cultural, and institutional variables of developing agriculture, forestry, livestock, and fisheries. The studies focus on farmers' values, needs and knowledge, their patterns of social organization, issues of food security, natural resource management and poverty reduction. Alternative models of multidisciplinary research, reuniting biological, natural, economic and social sciences are scrutinized in the light of experience and results, with emphasis on the nature of social science research as a source of international public goods and a key contributor to induced development.
