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 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. ÿTopics 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.

The dramatic increases in food prices experienced over the last four years, and their effects of hunger and food insecurity, as well as human-induced climate change and its implications for agriculture, food production and food security, are key topics within the field of agronomy and agricultural research. Contested Agronomy addresses these issues by exploring key developments since the mid-1970s, focusing in particular on the emergence of the neoliberal project and the rise of the participation and environmental agendas, taking into consideration how these have had profound impacts on the practice of agronomic research in the developing world especially over the last four decades. This book explores, through a series of case studies, the basis for a much needed ‘political agronomy’ analysis that highlights the impacts of problem framing and narratives, historical disjunctures, epistemic communities and the increasing pressure to demonstrate ‘success’ on both agricultural research and the farmers, processors and consumers it is meant to serve. Whilst being a fascinating and thought-provoking read for professionals in the Agriculture and Environmental sciences, it will also appeal to students and researchers in agricultural policy, development studies, geography, public administration, rural sociology, and science and technology studies.

This book discusses knowledge-based sustainable agro-ecological and natural resource management systems and best practices for sustained agricultural productivity and ecosystem resilience for better livelihoods under a changing climate. With a focus on agriculture in Africa, the book assesses innovative technologies for use on smallholder farms, and addresses some of the key Sustainable Development Goals to guide innovative responses and enhanced adaptation methods for coping with climate change. Contributions are based on 'Capacity Building for Managing Climate Change in Malawi' (CABMACC), a five-year program with an overall goal to improve livelihoods and food security through innovative responses and enhanced capacity of adaptation to climate change. Readers will discover more about sustainable crop production, climate smart agriculture, on-farm energy supply from biogas and the potential of soil carbon sequestration in crop-livestock systems.

Future climatic and agro-ecological changes in Africa are uncertain and associated with high degrees of spatial and temporal variability and this change is differently simulated within divergent climate-crop models and in controlled crop breeding stations. Furthermore, uncertainty emerges in local contexts, not just in response to climatic systems, but to social, economic, and political systems, and often with implications for the appropriateness and adoption of technologies or the success of alternative cropping systems. This book examines the challenges of adaptation in smallholder farming in Africa, analysing the social, economic, political and climatic uncertainties that impact on agriculture in the region and the range of solutions proposed. Drawing on case studies of genetically modified crops, conservation agriculture, and other 'climate smart' solutions in eastern and southern Africa, the book identifies how uncertainties are framed 'from above' as well experienced 'from below', by farmers themselves. It provides a compelling insight into why ideas about adaptation emerge, from whom, and with what implications. This book offers a unique perspective and will be highly relevant to students of climate change adaptation, food security and poverty alleviation, as well as policy-makers and field practitioners in international development and agronomy.

This book provides a new inter-disciplinary look at the practice and policies of conservation in Africa. Bringing together social scientists, anthropologists and historians with biologists for the first time, the book sheds some light on the previously neglected but critically important social aspects of conservation thinking. To date conservation has been very much the domain of the biologist, but the current ecological crisis in Africa and the failure of orthodox conservation policies demand a radical new appraisal of conventional practices. This new approach to conservation, the book argues, cannot deal simply with the survival of species and habitats, for the future of African wildlife is intimately tied to the future of African rural communities. Conservation must form an integral part of future policies for human development. The book emphasises this urgent need for a complementary rather than a competitive approach. It covers a wide range of topics important to this new approach, from wildlife management to soil conservation and from the Cape in the nineteenth century to Ethiopia in the 1980s. It is essential reading for all those concerned about people and conservation in Africa.

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.
