The unexplored potential of youth as the next frontier and workforce is a recent phenomenon in agricultural transformation in Africa.This calls for innovative approaches to create connections from the available human and technical competencies.Conservation agriculture and sustainable development are emerging lucrative economic domains.But, what is youth engagement in Africa? How do we engage youth in these economic domains? What are the lessons to be learned when youths are engaged in conservation agriculture and sustainable development? This book, therefore, provides a unique way to create new ideas, images, knowledge, and facts for use by farmers, students, youths, researchers, practitioners and scientists.This book should help to stimulate critical dialogue and resolve among readers on truly engaging youth in agricultural transformation.In using Zimbabwe, as the anchorage, the book, holistically scans the nation's landscape - food and nutrition security, climate change and variability, and the post-2015 development agenda, for examples of innovative thinking, leadership, and action, in youth engagement, and thus, catapults local futuristic-thinking youths to the global stage.
Sustainable Agriculture and the Environment describes the relationship of agriculture, society, nature and the environment, sustainable agriculture and sustainable development goals, management of biophysical resources for sustainable food and environment, traditional knowledge and innovative options, and social and policy aspects of sustainable agriculture. The book presents both environmental and economic principles, helping readers in the development and application of robust policy and good institutional systems that execute on sustainable agriculture practices for a healthy environment and to combat climate resilience. Includes case studies that provide real-world insights Relates traditional knowledge and innovation, maximizing the potential from both Reinforces our understanding of the role of sustainable agriculture in developing environmentally sustainable and profitable food systems
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.
Feeding the increasing global population, which is projected to reach ~10 billion by 2050, there has been increasing demands for more improved/sustainable agricultural management practices that can be followed by farmers to improve productivity without jeopardizing the environment and ecosystem. Indeed, about 95% of our food directly or indirectly comes from soil. It is a precious resource, and sustainable soil management is a critical socio–economic and environmental issue. Maintaining the environmental sustainability while the world is facing resource degradation, increasing climate change and population explosion is the current challenge of every food production sectors. Thus, there is an urgent need to evolve a holistic approach such as conservation agriculture to sustain higher crop productivity in the country without deteriorating soil health. Conservation Agriculture (CA), is a sustainable approach to manage agro–ecosystems in order to improve productivity, increase farm profitabilty and food security and also enhance the resource base and environment. Worldwide, it has been reported various benefits and prospects in adopting CA technologies in different agro-climatic conditions. Yet, CA in arid and semi-arid regions of India and parts of south Asia raises uncertainities due to its extreme climates, large scale residue burning, soil erosion and other constraints such as low water holding capacity, high potential evapotranspiration, etc . Thus, the proposed book has 30 chapters addressing all issues relevant to conservation agriculture/no-till farming system. The book also gives further strengthening existing knowledge in relation to soil physical, chemical and biological processes and health within close proximity of CA as well as machinery requirements. Moreover, the information on carbon (C) sequestration, C credits, greenhouse gas (GHG) emission, mitigation of climate change effects and socio-economic view on CA under diverse ecologies namely rainfed, irrigated and hill eco-region is also deliberated. For large scale adoption of CA practices in South Asian region especially in India and other countries need dissemination of best-bet CA technologies for dominant soil types/cropping systems through participatory mode, strong linkages and institutional mechanism and public-private-policy support. We hope this book gives a comprehensive and clear picture about conservation agriculture/no-till farming and its associated problem, challenges, prospects and benefits. This book shall be highly useful reference material to researchers, scientists, students, farmers and land managers for efficient and sustainable management of natural resources.
Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.
Anika Molesworth fell in love with her family's farm, a sheep station near Broken Hill, at an early age. She formed a bond with the land as though it were a member of her family. When the Millennium Drought hit, though, bringing with it heatwaves and duststorms, the future she'd always imagined for herself began to seem impossible. As she learned more about the causes of - and the solutions to - the extreme weather that was killing her land and her livelihood, Anika became fired up and determined to speak out. Talking to farmers and food producers all around the world, she soon realised that there was a way forward that could be both practical and sustainable - if only we can build up the courage to take it. Beautifully written and full of hope, Our Sunburnt Country shows that there is a way to protect our land, our food and our future, and it is within our grasp. Praise for Our Sunburnt Country: 'In Australia our climate debate can be depressing. In the hands of Anika Molesworth it is uplifting and full of hope.' - Craig Reucassel 'Anika Molesworth invites us to imagine a better future. Read this book and be inspired.' - Michael E. Mann 'In a hope-filled, personal tale framed by her family farm in a sun-baked landscape, Anika Molesworth weaves philosophy, science and a poet's eye into a heartwarming tale of how to help heal the planet.' - Matthew Evans 'This is an important, accessible and evocative book written by a farmer and scientist in that most vital of spaces: the future of our Earth. This book can be part of the solution.' - Charles Massy 'A personal journey spurred by climate change in the west of NSW, learning what can be done and why it is worth doing.' - Ross Garnaut
The purpose of this publication is to show how conservation agriculture can increase crop production while reducing erosion and reversing soil fertility decline, improving rural livelihoods and restoring the environment in developing countries. Soil organic matter and biological activity in the rooting zone, stimulated by continual additions of fresh organic material (crop residues and cover crops) are the basis of conservation agriculture, as described in the first chapter.
Conservation agriculture—consisting of four components including permanent soil cover, minimum soil disturbance, diversified crop rotations and integrated weed management—is considered the principal pathway to sustainable agriculture and the conservation of natural resources and the environment. Leading researchers in the field describe the basic principles of conservation agriculture, and synthesize recent advances and developments in conservation agriculture research. This book is a ready reference on conservation agriculture and reinforces the understanding for its utilization to develop environmentally sustainable and profitable food production systems. The book describes various elements of conservation agriculture; highlights the associated breeding and modeling efforts; analyses the experiences and challenges in conservation agriculture in different regions of the world; and proposes some pragmatic options and new areas of research in this very important area of agriculture.
