Available in PDF, EPUB and Kindle. Book excerpt: This book aims to help plant breeders by reviewing past achievements, currently successful practices, and emerging methods and techniques. Theoretical considerations are also presented to strike the right balance between being as simple as possible but as complex as necessary. The United Nations predicts that the global human population will continue rising to 9.0 billion by 2050. World food production will need to increase between 70-100 per cent in just 40 years. First generation bio-fuels are also using crops and cropland to produce energy rather than food. In addition, land area used for agriculture may remain static or even decrease as a result of degradation and climate change, despite more land being theoretically available, unless crops can be bred which tolerate associated abiotic stresses. Lastly, it is unlikely that steps can be taken to mitigate all of the climate change predicted to occur by 2050, and beyond, and hence adaptation of farming systems and crop production will be required to reduce predicted negative effects on yields that will occur without crop adaptation. Substantial progress will therefore be required in bridging the yield gap between what is currently achieved per unit of land and what should be possible in future, with the best farming methods and best storage and transportation of food, given the availability of suitably adapted cultivars, including adaptation to climate change. My book is divided into four parts: Part I is an historical introduction; Part II deals with the origin of genetic variation by mutation and recombination of DNA; Part III explains how the mating system of a crop species determines the genetic structure of its landraces; Part IV considers the three complementary options for future progress: use of sexual reproduction in further conventional breeding, base broadening and introgression; mutation breeding; and genetically modified crops.

Available in PDF, EPUB and Kindle. Book excerpt: Given the central role of the food and agriculture system in driving so many of the connected ecological, social and economic threats and challenges we currently face, Rethinking Food and Agriculture reviews, reassesses and reimagines the current food and agriculture system and the narrow paradigm in which it operates. Rethinking Food and Agriculture explores and uncovers some of the key historical, ethical, economic, social, cultural, political, and structural drivers and root causes of unsustainability, degradation of the agricultural environment, destruction of nature, short-comings in science and knowledge systems, inequality, hunger and food insecurity, and disharmony. It reviews efforts towards 'sustainable development', and reassesses whether these efforts have been implemented with adequate responsibility, acceptable societal and environmental costs and optimal engagement to secure sustainability, equity and justice. The book highlights the many ways that farmers and their communities, civil society groups, social movements, development experts, scientists and others have been raising awareness of these issues, implementing solutions and forging 'new ways forward', for example towards paradigms of agriculture, natural resource management and human nutrition which are more sustainable and just. Rethinking Food and Agriculture proposes ways to move beyond the current limited view of agro-ecological sustainability towards overall sustainability of the food and agriculture system based on the principle of 'inclusive responsibility'. Inclusive responsibility encourages ecosystem sustainability based on agro-ecological and planetary limits to sustainable resource use for production and livelihoods. Inclusive responsibility also places importance on quality of life, pluralism, equity and justice for all and emphasises the health, well-being, sovereignty, dignity and rights of producers, consumers and other stakeholders, as well as of nonhuman animals and the natural world. - Explores some of the key drivers and root causes of unsustainability , degradation of the agricultural environment and destruction of nature - Highlights the many ways that different stakeholders have been forging 'new ways forward' towards alternative paradigms of agriculture, human nutrition and political economy, which are more sustainable and just - Proposes ways to move beyong the current unsustainable exploitation of natural resources towards agroecological sustainability and overall sustainability of the food and agriculture system based on 'inclusive responsibility'

This book was released on 2019-05-14 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated History and Philosophy of Science (iHPS) is commonly understood as the study of science from a combined historical and philosophical perspective. Yet, since its gradual formation as a research field, the question of how to suitably integrate both perspectives remains open. This volume presents cutting edge research from junior iHPS scholars, and in doing so provides a snapshot of current developments within the field, explores the connection between iHPS and other academic disciplines, and demonstrates some of the topics that are attracting the attention of scholars who will help define the future of iHPS.

Book excerpt: Most of us have heard of green belts – but how much do we really know about them? This book tries to separate the fact from the fiction when it comes to green belts by looking both backwards and forwards. They were introduced in the mid-twentieth century to try and stop cities merging together as they grew. There is little doubt they have been very effective at doing that, but at what cost? Are green belts still the answer to today’s problems of an increasing population and ever higher demands on our natural resources? Green Belts: Past; present; future? reflects upon green belts in the United Kingdom at a time when they have perhaps never been more valued by the public or under more pressure from development. The book begins with a historical study of the development of green belt ideas, policy and practice from the nineteenth century to the present. It discusses the impacts and characteristics of green belts and attempts to reconcile perceptions and reality. By observing examples of green belts and similar policies in other parts of the world, the authors ask what we want green belts to achieve and suggest alternative ways in which that could be done, before looking forward to consider how things might change in the coming years. This book draws together information from a range of sources to present, for the first time, a comprehensive study of green belts in the UK. It reflects upon the gap between perception and reality about green belts, analyses their impacts on rural and urban areas, and questions why they retain such popular support and whether they are still the right solution for the UK and elsewhere. It will be of interest to anyone who is concerned with planning and development and how we can provide the homes, jobs and services we need while protecting our more valuable natural assets.

Available in PDF, EPUB and Kindle. Book excerpt: "In the seemingly mundane Northern farm of early America and the people who sought to improve its productivity and efficiency, Emily Pawley finds a world rich with innovative practices and marked by a developing interrelationship between scientific knowledge, industrial methods, and capitalism. Agricultural "improvers" became increasingly scientistic, driving tremendous increases in the range and volume of agricultural output-and transforming American conceptions of expertise, success, and exploitation. Pawley's focus on soil, fertilizer, apples, mulberries, agricultural fairs, and experimental stations shows each nominally dull subject to have been an area of intellectual ferment and sharp contestation: mercantile, epistemological, and otherwise"--

Book excerpt: Faced with a global threat to food security, it is perfectly possible that society will respond, not by a dystopian disintegration, but rather by reasserting co-operative traditions. This book, by a leading expert in urban agriculture, offers a genuine solution to today’s global food crisis. By contributing more to feeding themselves, cities can allow breathing space for the rural sector to convert to more organic sustainable approaches. Biel’s approach connects with current debates about agroecology and food sovereignty, asks key questions, and proposes lines of future research. He suggests that today’s food insecurity – manifested in a regime of wildly fluctuating prices – reflects not just temporary stresses in the existing mode of production, but more profoundly the troubled process of generating a new one. He argues that the solution cannot be implemented at a merely technical or political level: the force of change can only be driven by the kind of social movements which are now daring to challenge the existing unsustainable order.Drawing on both his academic research and teaching, and 15 years’ experience as a practicing urban farmer, Biel brings a unique interdisciplinary approach to this key global issue, creating a dialogue between the physical and social sciences
