Agogic Maps: From Musical Phrasing to Enhancement of Urban Spaces (SpringerBriefs in Applied Sciences and Technology)
by Raffaele PeThis book explores the value of the musical concept of "agogics" - the modification of regular rhythm to enhance expressive potential - in understanding urban spatial configurations within the current technological context and in developing urban maps that exploit sonic signals to create an open learning framework. The book starts by discussing the meaning and significance of agogics in the musical and artistic realm, with reference to the work of Adolphe Appia, Emile-Jaques Dalcroze, and Iannis Xenakis, among others. Its relevance to cartography and mapping is then examined, taking into account the contributions of Ian McHarg, Bill Hillier, Mark Shepard, and Robin Minard. The nature and value of agogic maps, for example in fostering awareness of place and effective organization of spatial development, are described in detail, with reference to case studies in Dar es Salaam, Tanzania and Segrate, Italy. It is explained how agogic maps take advantage of innovative categories and scripting equipment to provide a new mapping instrument for spatial and urban configurations, highlighting the interdependence between aural signals and spatial variables. This book will be of interest to architects, urbanists, and musicians with a specific interest in space and sound design.
Agrarian Dreams
by Julie GuthmanIn this groundbreaking study of organic farming, Julie Guthman challenges accepted wisdom about organic food and agriculture in the Golden State. Many continue to believe that small-scale organic farming is the answer to our environmental and health problems, but Guthman refutes popular portrayals that pit "small organic" against "big organic" and offers an alternative analysis that underscores the limits of an organic label as a pathway to transforming agriculture. This second edition includes a thorough investigation of the federal organic program, a discussion of how the certification arena has continued to grow and change since its implementation, and an up-to-date guide to the structure of the organic farming sector. Agrarian Dreams delivers an indispensable examination of organic farming in California and will appeal to readers in a variety of areas, including food studies, agriculture, environmental studies, anthropology, sociology, geography, and history.
Agrarian Dreams: The Paradox of Organic Farming in California
by Julie GuthmanIn this comprehensive study of organic farming in California, Julie Guthman casts doubt on the current wisdom about organic food and agriculture, at least as it has evolved in the Golden State. Refuting popular portrayals of organic agriculture as a small-scale family farm endeavor in opposition to "industrial" agriculture, Guthman explains how organic farming has replicated what it set out to oppose.
Agrarian Dreams: The Paradox of Organic Farming in California
by Julie GuthmanIn an era of escalating food politics, many believe organic farming to be the agrarian answer. In this first comprehensive study of organic farming in California, Julie Guthman casts doubt on the current wisdom about organic food and agriculture, at least as it has evolved in the Golden State. Refuting popular portrayals of organic agriculture as a small-scale family farm endeavor in opposition to "industrial" agriculture, Guthman explains how organic farming has replicated what it set out to oppose.
Agrarian Environments: Resources, Representations, and Rule in India
by David Gilmartin K. Sivaramakrishnan Margaret Mckean Arun Agrawal Peter VandergeestAgrarian Environments questions the dichotomies that have structured earlier analyses of environmental processes in India and offers a new way of looking at the relationship between agrarian transformation and environmental change. The contributors claim that attempts to explain environmental conflicts in terms of the local versus the global, indigenous versus outsiders, women versus men, or the community versus the market or state obscure vital dynamics of mobilization and organization that critically influence thought and policy. Editors Arun Agrawal and K. Sivaramakrishnan claim that rural social change in India cannot be understood without exploring how environmental changes articulate major aspects of agrarian transformations--technological, cultural, and political--in the last two centuries. In order to examine these issues, they have reached beyond the confines of single disciplinary allegiances or methodological loyalties to bring together anthropologists, historians, political scientists, geographers, and environmental scientists who are significantly informed by interdisciplinary research. Drawing on extensive field and archival research, the contributors demonstrate the powerful political implications of blurring the boundaries between dichotomous cultural representations, combine conceptual analyses with specific case studies, and look at why competing powers chose to emphasize particular representations of land use or social relations. By providing a more textured analysis of how categories emerge and change, this work offers the possibility of creating crucial alliances across populations that have historically been assumed to lack mutual goals. Agrarian Environments will be valuable to those in political science, Asian studies, and environmental studies.Contributors.

Agrarian Systems and Climate Change: Journeys of adaptation in the Global South
by Hubert Cochet Olivier Ducourtieux Nadège GaramboisThis book examines the link between global change and impacts and adaptation at the local level, combining a systemic approach and connecting different scales of analysis. It unravels the complex ties between the scenarios developed at global, continental, regional scales of analysis and farmers' concrete experiences, lived at the territorial level. In addition to this great discrepancy in terms of scales of analysis and understanding of processes, there is a need to relate the multi-generational scale of possible climatic changes to that of agricultural practices carried out on the agricultural season level. Based on the detailed study and comparison of a dozen contrasting local situations in sub-Saharan Africa and South-East Asia, the authors highlight the processes and trajectories which explain the high exposure to the hazards of different groups of farmers, as well as their unequal capacity to adapt. They explain the causes of this vulnerability and illustrate the weight of past and current choices in terms of agricultural, environmental and trade policies. Finally, they present the adjustment modalities and the past and current transformations of peasant practices moving towards a reduction in exposure to hazards, a reduction in vulnerability, and better adaptation to global changes: climate change, demographic growth, increased competition for access to resources, changes in relative prices and market fluctuations, deregulation and decline in public support, etc. In conclusion, they outline possible paths in terms of adaptation and proposals for political measures to support producers.

Agri-Culture: "Reconnecting People, Land and Nature"
by Jules Pretty'Refreshingly fluent narrative, brimming full of stories and metaphors' Tim O'Riordan, University of East Anglia, UK 'A great balance between storytelling and analysis which points to the critical need for gaining control over resources' Jacqueline Ashby, CIAT, Colombia 'Full of supporting evidence and clear arguments' Norman Uphoff, Cornell University, US 'A wonderful book, put together with such vision and passion' Mark Ritchie, Institute of Agriculture and Trade Policy, US 'A superb volume. This is a valuable monograph that all policy-makers, scholars and farmers must read to understand their roles and responsibilities' Vo-Tong Xuan, Angiang University, Vietnam 'Beautifully written. The implications of the book's ideas are deep and extensive' Julia Guivant, University of Florianopolis, Brazil Something is wrong with our agricultural and food systems. Despite great progress in increasing productivity in recent decades, hundreds of millions of people remain hungry and malnourished, and further millions suffer for eating too much food or the wrong sort. Agri-Culture envisages the expansion of a new form of food production and consumption founded on more ecological principles and in harmony with the cultures, knowledges and collective capacities of the producers themselves. It draws on many stories of successful agricultural transformation in developing and industrialized countries, but with a warning that true prosperity will depend on the radical reform of the institutions and policies that control global food futures, and fundamental changes in the way we think. The time has come for the next agricultural revolution.

AgriCultura: Urban Agriculture and the Heritage Potential of Agrarian Landscape (Urban Agriculture)
by Lionella Scazzosi Paola BranduiniThis book explains how cultural heritage can be a tool for enhancing urban agriculture and improving landscape and life quality. It cuts across the existing literature and fills the gaps between urban agriculture, considered as a food, social and environmental opportunity and cultural heritage, considered as resource. It focuses the role of the countryside for urban areas, in the history of the city and today. Its attention is on the quality for all areas, both outstanding, ordinary and degraded, as well as large, little or fragmented (European landscape convention 2000). It considers agricultural landscape as a system of tangible and intangible heritage components and relationships, to be retained, enhanced and transmit, in a process of inevitable but appropriate dynamic conservation and management over time (ICOMOS-IFLA Principles 2017). This book can benefit the collaboration among local players – such as farmers, citizens, associations, public institutions, stakeholders – in conserving and enhancing agrarian heritage and reinforcing the identity of places and people. It can strengthen collective action and generate positive effects on good large and local -scale management. The first part has a methodological character in order to enlighten the integrated approach between cultural heritage and urban agriculture. The second part exemplifies cases where the heritage has been recognised but not yet translated into concrete action. The third Part discloses ongoing process of co-construction, where policies have recognized the cultural, environmental and social meaning of urban agriculture as heritage. This book aims to reach scholars, local administrations, professionals, farmers and citizens. It involves many authors, many of whom are directly engaged with action-research in safeguarding and implementing the mutual interaction between urban agriculture activities and agrarian heritage.
