Conservation Agriculture: A Sustainable Approach for Soil Health and Food Security [PDF ebook] 
Conservation Agriculture for Sustainable Agriculture

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.

Dr. Somasundaram Jayaraman has graduated from Faculty of Agriculture, Annamalai University (1995) and  post-graduation (1998) and Doctorate (2001) from Tamil Nadu Agricultural University (TNAU) in Coimbatore, Tamil Nadu, India. Presently he is a Principal Scientist at Division of Soil Physics, ICAR–Indian Institute of Soil Science, Bhopal, Madhya Pradesh, India.  He has more than 2 decades of experience in research and training in the field of natural resource management/conservation agriculture on soil properties and carbon sequestration. He has developed conservation agricultural practices for enhancing soil health and crop productivity in Western and Central India.  In addition, farmers in rainfed regions of Central India were also sensitized about soil health and developed low cost farmer-friendly tools for assessing soil health in a participatory mode through field demonstrations He has published more than 75 research papers of national and international repute. In addition, he has authored/edited 5 books and published more than 25 book chapters. Besides, he has mentored post-graduate students, Ph D scholars, and young scientists.Dr. Jayaraman received Endeavour Research Fellow by Australian Government in 2015, Australian Awards Ambassador by Australian High Commission to India in 2018, the Scientist Award in 2018 and Leadership Award by SCSI, New Delhi in 2019.
 Professor Ram C. Dalal has graduated from the Punjab Agricultural University (1964) completed his Master and Ph D from Indian Agricultural Research Institute (1969). Presently he is a Professor /Adjunct Professor in the School of Agriculture and Food Science at the University of Queensland, Brisbane, Australia, and Adjunct Professor at Uttar Banga Krishi Vishwavidalya, Pundibari, Coochbehar, India. During last five decades of research and teaching experience, he has contributed significantly to create awareness in the farming, scientific and general community to the seriousness and insidious nature of soil degradation. For the last 25 years, landscape restoration, soil organic matter management, carbon sequestration and nitrogen management, and site-specific management for soil and subsoil and other constraints and sustainable crop and pasture rotations and vegetation management have been the central research platforms across cropping, rangelands and forestry ecosystems.
