Book excerpt: Este livro visa estabelecer a relação entre agroenergia e o reconhecimento das funções públicas da agricultura familiar assim como compreender a evolução e as transformações do sistema agrário de Irecê, semiárido da Bahia, Brasil. Em mais uma oportunidade, esta pesquisa contou com a participação das agricultoras e agricultores familiares durante as entrevistas de campo a quem agradecemos pela paciência, por nos receberem em suas residências, para breves conversas. Utiliza-se o Método Análise-diagnóstico em sistemas agrários, e abordam-se os impactos das políticas públicas federais na cadeia produtiva do biodiesel no território. No sertão semiárido, este tema ganha mais relevância em virtude das condições naturais de escassez hídrica relacionadas a cinco séculos de desmatamento da caatinga e existência de pobreza extrema. Observa-se que todos os sistemas de produção agrícola apresentaram lavouras irrigadas e classificados com restrição ambiental endógena elevada. Na combinação de três critérios, sua perspectiva foi considerada durável constrangida (incerta e limitada em tempo e espaço).

This book was released on 2015 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Esta tese visou compreender o estado atual de estruturação da cadeia produtiva do biodiesel no Território de Irecê, semiárido da Bahia, realizando pesquisa de campo e pesquisas teóricas sobre a formação do sistema agrário regional, utilizando o Método Análise-diagnóstico em sistemas agrários, e os impactos das recentes políticas públicas federais na cadeia produtiva do biodiesel no território. Este estudo é relacionado ao reconhecimento das funções públicas da agricultura familiar, tais como as funções econômica, social, cultural, territorial e educativa que norteiam a noção de multifuncionalidade da agricultura familiar. No sertão semiárido, este tema ganha mais relevância em virtude das condições naturais de escassez hídrica relacionadas a cinco séculos de desmatamento da caatinga e existência de pobreza extrema. O Plano Brasil sem Miséria e o novo Código Florestal do Brasil, de 2012 apontam nesta direção através dos serviços ambientais, vinculando-os à extrema pobreza. Os tipos de famílias cujos sistemas de produção possuem sistemas de irrigação possuem sustentabilidade constrangida, em virtude de problemas de escassez de água extraída de mananciais subterrâneos da região, no curto e longo prazos. Foram identificados nesta situação os seguintes tipos; Família agrícola diversificada, capitalizada com lavouras irrigadas e integrada ao mercado com aposentadoria; Família pluriativa capitalizada, com lavouras irrigadas e integrada ao mercado com aposentadoria; Família pluriativa com lavouras irrigadas, aposentadoria e bolsa família; Família pluriativa com aposentadoria e lavouras irrigadas; Família agrícola com lavouras irrigadas e Família agrícola com aposentadoria e lavouras irrigadas. As famílias obtêm rendimentos de atividades agrícolas e não-agrícolas e aquelas famílias com aposentadoria apresentam a renda agrícola igual ou superior a 50% da renda familiar. Os tipos de famílias capitalizadas que utilizam sistemas irrigados possuem rendimentos agrícolas bem acima de 50%, a exemplo da Família agrícola diversificada, capitalizada com lavouras irrigadas e integrada ao mercado com aposentadoria e a Família agrícola diversificada, capitalizada com lavouras irrigadas e integrada ao mercado com aposentadoria.

Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

This book was released on 2008-09-15 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ants are probably the most dominant insect group on Earth, representing ten to fifteen percent of animal biomass in terrestrial ecosystems. Flowering plants, meanwhile, owe their evolutionary success to an array of interspecific interactions—such as pollination, seed dispersal, and herbivory—that have helped to shape their great diversity. The Ecology and Evolution of Ant-Plant Interactions brings together findings from the scientific literature on the coevolution of ants and plants to provide a better understanding of the unparalleled success of these two remarkable groups, of interspecific interactions in general, and ultimately of terrestrial biological communities. The Ecology and Evolution of Ant-Plant Interactions synthesizes the dynamics of ant-plant interactions, including the sources of variation in their outcomes. Victor Rico-Gray and Paulo S. Oliveira capture both the emerging appreciation of the importance of these interactions within ecosystems and the developing approaches that place studies of these interactions into a broader ecological and evolutionary context. The collaboration of two internationally renowned scientists, The Ecology and Evolution of Ant-Plant Interactions will become a standard reference for understanding the complex interactions between these two taxa.

Book excerpt: As Eugene Wigner stressed, mathematics has proven unreasonably effective in the physical sciences and their technological applications. The role of mathematics in the biological, medical and social sciences has been much more modest but has recently grown thanks to the simulation capacity offered by modern computers. This book traces the history of population dynamics---a theoretical subject closely connected to genetics, ecology, epidemiology and demography---where mathematics has brought significant insights. It presents an overview of the genesis of several important themes: exponential growth, from Euler and Malthus to the Chinese one-child policy; the development of stochastic models, from Mendel's laws and the question of extinction of family names to percolation theory for the spread of epidemics, and chaotic populations, where determinism and randomness intertwine. The reader of this book will see, from a different perspective, the problems that scientists face when governments ask for reliable predictions to help control epidemics (AIDS, SARS, swine flu), manage renewable resources (fishing quotas, spread of genetically modified organisms) or anticipate demographic evolutions such as aging.

Available in PDF, EPUB and Kindle. Book excerpt: In Territories of Difference, Arturo Escobar, author of the widely debated book Encountering Development, analyzes the politics of difference enacted by specific place-based ethnic and environmental movements in the context of neoliberal globalization. His analysis is based on his many years of engagement with a group of Afro-Colombian activists of Colombia’s Pacific rainforest region, the Proceso de Comunidades Negras (PCN). Escobar offers a detailed ethnographic account of PCN’s visions, strategies, and practices, and he chronicles and analyzes the movement’s struggles for autonomy, territory, justice, and cultural recognition. Yet he also does much more. Consistently emphasizing the value of local activist knowledge for both understanding and social action and drawing on multiple strands of critical scholarship, Escobar proposes new ways for scholars and activists to examine and apprehend the momentous, complex processes engulfing regions such as the Colombian Pacific today. Escobar illuminates many interrelated dynamics, including the Colombian government’s policies of development and pluralism that created conditions for the emergence of black and indigenous social movements and those movements’ efforts to steer the region in particular directions. He examines attempts by capitalists to appropriate the rainforest and extract resources, by developers to set the region on the path of modernist progress, and by biologists and others to defend this incredibly rich biodiversity “hot-spot” from the most predatory activities of capitalists and developers. He also looks at the attempts of academics, activists, and intellectuals to understand all of these complicated processes. Territories of Difference is Escobar’s effort to think with Afro-Colombian intellectual-activists who aim to move beyond the limits of Eurocentric paradigms as they confront the ravages of neoliberal globalization and seek to defend their place-based cultures and territories.

Available in PDF, EPUB and Kindle. Book excerpt: Why does land management so often fail to prevent soil erosion, deforestation, salination and flooding? How serious are these problems, and for whom? This book, first published in 1987, sets out to answer these questions, which are still some of the most crucial issues in development today, using an approach called ‘regional political ecology’. This approach acknowledges that the reason why land management can fail are extremely varied, and must include a thorough understanding of the changing natural resource base itself, the human response to this, and broader changes in society, of which land managers are a part. Land Degradation and Society is essential reading for all students of geography, agriculture, social sciences, development studies and related subjects.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the threated Amazon of his native Brazil, Boff traces the economic and metaphysical ties that bind the fate of the rain forests with the fate of the indigenous peopls and the poor of the land. He shows how liberation theology must join with ecology in reclaiming the dignity of the earth and our sense of a common community, part of God's creation. To illustrate the possibilities, Boff turns to resrouces in Christian spirituality both ancient and modern, from the vision of St. Francis of Assisi to cosmic christology.

Book excerpt: Over the last two decades, the environmental cost of capital accumulation has emerged as a serious social and economic problem. Many are now aware that the ways we utilize our natural and cultural resources have had a range of negative consequences internationally--from the destabilization of ecosystems, the depletion of resources, and the degradation of our environment to the disintegration of cultural values and ethnic identity within local communities. Responses to this dilemma have varied, with traditional economists characterizing environmental issues as mere externalities and many ecologists focusing solely on protecting the environment. Offering a far more comprehensive view, Enrique Leff provides a Marxist approach to environment and development that focuses on the process of production, as well as implications of the environmental crisis on human values. To truly achieve a more rational and integrated use of our natural resources, he convincingly argues for a reorientation of science and technology towards the objectives of sustainable development, the decentralization of production, and the participatory management of natural resources.

Available in PDF, EPUB and Kindle. Book excerpt: Until very recently, studies of the environmental movement have been heavily biased towards the North Atlantic worlds. There was a common assumption amongst historians and sociologists that concerns over such issues as conservation or biodiversity were the exclusive preserve of the affluent westerner: the ultimate luxury of the consumer society. Citizens of the world's poorest countries, ran the conventional wisdom, had nothing to gain from environmental concerns; they were 'too poor to be green', and were attending to the more urgent business of survival. Yet strong environmental movements have sprung up over recent decades in some of the poorest countries in Asia and Latin America, albeit with origins and forms of expression quite distinct from their western counterparts. In Varieties of Environmentalism, Guha and Matinez-Alier seek to articulate the values and orientation of the environmentalism of the poor, and to explore the conflicting priorities of South and North that were so dramatically highlighted at the Rio Earth Summit in 1992. Essays on the 'ecology of affluence' are also included, placing ion context such uniquely western phenomena as the 'cult of wilderness' and the environmental justice movement. Using a combination of archival and field data,. The book presents analyses of environmental conflicts and ideologies in four continents: North and South America, Asia and Europe. The authors present the nature and history of environmental movements in quite a new light, one which clarifies the issues and the processes behind them. They also provide reappraisals for three seminal figures, Gandhi, Georgescu-Roegen and Mumford, whose legacy may yet contribute to a greater cross-cultural understanding within the environmental movements.

Available in PDF, EPUB and Kindle. Book excerpt: The Routledge Handbook of Political Ecology presents a comprehensive and authoritative examination of the rapidly growing field of political ecology. Located at the intersection of geography, anthropology, sociology, and environmental history, political ecology is one of the most vibrant and conceptually diverse fields of inquiry into nature-society relations within the social sciences. The Handbook serves as an essential guide to this rapidly evolving intellectual landscape. With contributions from over 50 leading authors, the Handbook presents a systematic overview of political ecology’s origins, practices and core concerns, and aims to advance both ongoing and emerging debates. While there are numerous edited volumes, textbooks, and monographs under the heading ‘political ecology,’ these have tended to be relatively narrow in scope, either as collections of empirically based (mostly case study) research on a given theme, or broad overviews of the field aimed at undergraduate audiences. The Routledge Handbook of Political Ecology is the first systematic, comprehensive overview of the field. With authors from North and South America, Europe, Australia and elsewhere, the Handbook of Political Ecology provides a state of the art examination of political ecology; addresses ongoing and emerging debates in this rapidly evolving field; and charts new agendas for research, policy, and activism. The Routledge Handbook of Political Ecology introduces political ecology as an interdisciplinary academic field. By presenting a ‘state of the art’ examination of the field, it will serve as an invaluable resource for students and scholars. It not only critically reviews the key debates in the field, but develops them. The Handbook will serve as an excellent resource for graduate and advanced undergraduate teaching, and is a key reference text for geographers, anthropologists, sociologists, environmental historians, and others working in and around political ecology.

This book examines wide variety of ways in which environmental deterioration, in particular soil erosion, can be viewed and the implicit political judgements that often inform them. Using the context of developing countries, where the effects tend to be more acute due to underdevelopment and climatic factors, this work aims to examine this source of uncertainty and make explicit the underlying assumptions in the debate about soil erosion. It also rejects the notion that soil erosion is a politically neutral issue and argues that conservation requires fundamental social change. This title will be of interest to students of environmental and developmental studies.
