Organic Agriculture And Climate Change Mitigation

In the coming time people, will face changes in climate patterns that will contribute to severe water shartage or flooding, and rising temperatures that will cause shifts in crop growing seasons. Due to this there will be shortage of food and distribution of disease vectors, putting population at greater health and life risks. The productivity of farms is likely to diminish because of climate change, espcially in the poorest countries. Increased drought periods in many parts of the world and erratic rainfalls will endanger yield stability and put global food production at risk. Information contain in this book will not only enhance climate change mitigation activities which will have broad benefits, it also can provide the data to verify the mitigation benefits of organic agriculture which will allow organic farmers to increase their participation in carbon markets. The present book would prove useful for post graduate students of Agriculture, Soil Science, Climate Change and Agriculture agencies.

This book will collate, review and synthesize information on how Organic Agriculture (OA) practices affect and are affected by climate change, in comparison to the more widely used conventional agricultural practices. Pros and cons of OA practices will be discussed separately for croplands, pasture lands, mixed livestock cropping systems, vegetable fields, fruit and tree orchards, and vineyards. The book concludes with an overview on how conventional and OA practices can be prudently and discriminately combined to identify and adopt climate-resilient agro-ecosystems under site-specific conditions.

Organic agriculture is defined as an environmentally and socially sensitive food supply system. This publication considers the contribution of organic agriculture to ecological health, international markets and local food security. It contains a number of case studies of the practical experiences of small farmers throughout the world (including India, Iran, Thailand, Uganda and Brazil) who have adopted fully integrated food systems, and analyses the prospects for a wider adoption of organic agriculture. The book also discusses the weakness of institutional support for nurturing existing knowledge and exchange in organic agriculture.

According to IPCC reports, one of the greatest threats to the Earth ecosystems is climate change caused by the anthropogenic emissions of greenhouse gases, mostly carbon dioxide, mainly from the combustion of fossil fuels, cement production and land-use change which leads to an excessive temperature rise. Agriculture and forestry are responsible for quiet big emissions of greenhouse gases: CO2, CH4 and N2O, and have significant potential to reduce these emissions mainly through enhancement of CO2 absorption by terrestrial ecosystems. To evaluate the impact of agriculture on climate change, ruminant farming should be also taken into account. These animals emit considerable amounts of methane which has strong greenhouse effects. Methane emissions may be reduced by using appropriate feed for ruminants. Decreasing the meat consumption of these animals can also make an important contribution to reducing methane emissions. The methods for reducing greenhouse gas emissions through appropriate management of terrestrial ecosystems and animal husbandry are widely discussed in The Role of Agriculture in Climate Change Mitigation. The book will be of interest to academics, professionals and policy makers in environmental sciences.

One of the challenges under current land management practices is to increase food and soil security to meet projected trends in food production, while maintaining the resilience to climate change. This book provides a forum for researchers to access the most recent developments in enhancing carbon sinks and minimizing greenhouse gas emissions. It suggests that policies and practices integrating microbial technology, modern crop cultivars, conservation practices, increased manure application, organic farming and agroforestry have a greater capacity to sequester carbon and reduce carbon-based greenhouse gases, leading to more robust agroecosystems compared to conventional agriculture. It is argued that empirical models can represent powerful tools for assessing how mitigation and adaptation strategies can be used to optimize crop yield and minimize greenhouse gas emissions under future climate change scenarios. 'Sustainable agroecosystems in climate change mitigation' bridges our current knowledge gaps and recognizes the contribution of sustainable agricultural practices as a way forward in reducing the global carbon and nitrogen footprint. It is relevant for students, researchers, governmental and non-governmental organisations interested in climate change mitigation, sustainable agriculture, soil science, modern analytical techniques and modelling. It answers the questions: 'How can sustainable agroecosystems help mitigate climate change?' and 'What are the tools to achieve this goal?'

Global climate change threatens human existence through its potential impact on agriculture and the environment. Agriculture is climate-sensitive, and climate variability and climate change have net negative impact on it. Additionally, the agricultural landscape is affected by monoculture and agro-biodiversity loss, soil fertility depletion and soil loss, competition from biofuel production, crop yield plateaus and invasive species. Nevertheless, the global agricultural production system has to meet the food demands from the growing human population, which is set to exceed 10 billion by 2050. This book discusses the impacts of climate change on agriculture, animal husbandry and rural livelihoods. Further, since agriculture, forestry and other land-use sectors contribute about 10–12 gigatonnes of CO2-equivalent per year, it argues that agricultural policy must dovetail adaptation and mitigation strategies to reduce greenhouse gases emissions. This calls for a reformative and disruptive agricultural strategy like climate-smart agriculture, which can operate at all spatio-temporal scales with few modifications. The book also redefines sustainable agriculture through the lens of climate-smart agriculture in the context of the sustainability of Earth's life- support system and inter- and intra-generational equity. The climate-smart agriculture approach is gaining currency thanks to its inherent positive potential, and its goal to establish an agricultural system which includes "climate-smart food systems", "climate-proof farms", and "climate-smart soils". Climate-smart agriculture provides a pathway to achieve sustainable development goals which focus on poverty reduction, food security, and environmental health.

“Soil Health and Climate Change” presents a comprehensive overview of the concept of soil health, including the significance of key soil attributes and management of soil health in conventional and emerging land use systems in the context of climate change. Starting with a review of the physical, chemical and biological indicators of soil health and their significance for monitoring the impacts of climate change, this book then focuses on describing the role of soil structure, pH, organic matter, nitrogen, respiration and biota in sustaining the basic functions of soil ecosystems, and their anticipated responses to climate change. Further topics include the management of cropping, pastoral, and forestry systems, and rehabilitated mine sites, with a focus on mitigation of and adaptation to climate change impacts. Finally, the opportunities and potential risks of organic farming, biochar and bioenergy systems, and their ability to sustain and even enhance soil health, are discussed.
