Bioenergy is coming to be seen as a priority on the international agenda, with the use of liquid biofuels a key strategy in the attempt to meet both the demand for environmental sustainability and the energy needs of countries. The growth in the production and use of biofuels around the world has led to increased interest and discussion about this subject. Given the dynamics of this phenomenon, the organizers of this book, based on more than 10 years experience of joint research on this subject, seek to address key issues relating to the production and marketing of liquid biofuels using the Brazilian experience with ethanol and biodiesel as an illustrative case, as well as the experiences of the leading producers and consumers of biofuels. The topics to be covered in this book include the role of public policies in fostering the emergence of the biofuels industry, the main socio-economic, environmental, technological aspects and the prospects for the sector. The conceptual and methodological bases that provide analytical support to the book are based on recent research published in indexed journals. The structure and content of the book seek to address some central issues regarding: How the biofuel industries have emerged and developed in different countries? What factors have been crucial to the success or failure of different production initiatives? What are the main socio-economic-environmental impacts of the production and consumption of liquid biofuels? How are national and international markets for liquid biofuels being structured? To what extent and/or in what conditions can the experiences and lessons learned at the national level be transferred and adapted in other countries? Finally, based on the scenarios, the prospects for liquid biofuels will be discussed.

In the last few decades, Brazilian agriculture has experienced a seismic transformation, and its contradictory facets have fed different and opposing narratives regarding recent changes. This book covers these changes, exploring the issues from several empirical and analytical angles, including the role of agriculture in the contemporary Brazilian economy, the dynamics of Brazilian agricultural value chains, environmental challenges and the processes of social differentiation. Brazilian agriculture continues to be viewed in the international literature, either through the lenses of the past century – those of former problems relating to land use and land tenure – or apologetically. This collection of essays aims at updating the current interpretations, providing objective accounting of the main transformations, its determinants, results, contradictions and limitations. As it covers the most relevant traits of Brazilian agricultural and rural development, the book will provide the reader with an encompassing view of contemporary Brazilian agriculture, including the positive and negative sides of the so-called tropical agriculture revolution. It highlights the tremendous economic potential as well as the continuing structural heterogeneity, concentration of production and marginalization of millions of small farmers. Written in an engaging and accessible style, this book will be perfect for all those interested in learning about Brazilian agriculture. It will be of particular interest to undergraduate and graduate students of economic development, agricultural economics, rural sociology, comparative economic development, rural development and agricultural policies.

O agronegócio vive uma era de transformação tecnológica, impulsionada pela Agricultura de Precisão (AP). Essa abordagem inovadora utiliza tecnologias para otimizar a produção agrícola, levando em consideração a variabilidade espacial e temporal do solo, das culturas e das condições climáticas. Este guia prático tem como objetivo fornecer aos produtores rurais um roteiro completo para implementar a AP em suas propriedades. Abordaremos desde as tecnologias básicas até a criação de mapas de manejo e a análise de cases de sucesso. Tecnologias para Agricultura de Precisão A AP se baseia em um conjunto de tecnologias que permitem a coleta, análise e gestão de dados georreferenciados da lavoura. As principais tecnologias utilizadas na AP são: •GPS: O Sistema de Posicionamento Global fornece a localização precisa de máquinas e implementos agrícolas, permitindo a navegação precisa e a aplicação de insumos em áreas específicas. •Drones: Aeronaves não tripuladas equipadas com sensores podem ser utilizadas para mapear a lavoura, coletando imagens aéreas em alta resolução para análise da saúde das plantas, identificação de problemas e monitoramento da produtividade. •Sensores: Diversos tipos de sensores são utilizados para coletar dados sobre o solo, as plantas e o clima, como pH, nutrientes, umidade, temperatura e índice de área foliar. •Softwares: Softwares específicos são utilizados para processar e analisar os dados coletados, gerar mapas de manejo e auxiliar na tomada de decisões. Criação de Mapas de Manejo A partir dos dados coletados, é possível criar mapas de manejo para diferentes aspectos da produção agrícola, como: •Fertilidade do solo: Os mapas de fertilidade indicam a variabilidade espacial dos nutrientes no solo, permitindo a aplicação precisa de fertilizantes, evitando desperdícios e otimizando a nutrição das plantas. •Irrigação: Os mapas de irrigação identificam as áreas da lavoura com diferentes necessidades de água, possibilitando a aplicação precisa de água e o uso eficiente desse recurso vital. •Manejo de pragas e doenças: Os mapas de manejo de pragas e doenças identificam as áreas com maior risco de infestação, permitindo a aplicação direcionada de defensivos agrícolas e o controle mais eficaz de pragas e doenças.

This book is a contribution of the authors to the food - fuel debate. During 2007 and 2008 several factors led to the food inflation problem: growing population, income distribution, urbanization, biofuel, social programs, production scarcity etc.. Biofuel got most of the blame for food inflation but its responsibility was only limited. There are several possibilities of solving the food inflation problem that are discussed this book. It explores the example of Brazil’s agricultural sector, where a quiet revolution occurred in the last 15 years. This development is leading to Brazil becoming one of the largest food exporters globally. This position will strengthen as an additional 100 million hectares becomes available for crop development. The second part of the book explores the basics of the sugar cane chain. Sugar cane occupies less than 2% of Brazilian arable land and supplies 50% of Brazilian car fuel. In 2010 Brazil produced 53% of the world’s sugar. Sugar cane produces sugar, ethanol (used as car fuel), biogases that are used to co-generate electricity and other by-products. Biofuel is a booming industry. New technologies allow production of diesel and other fuels from cane. Sugar cane ethanol is the only renewable fuel that can currently compete with gasoline. Coca Cola just launched the plastic bottle with sugar cane plastic. This book helps us to understand Brazilian agribusiness and sugar cane economics from various perspectives e.g. international investments, sustainability, future trends and the strategic plan for the Brazilian industry.

This book explores the agrifood system transitions in Brazil to provide a new understanding of the trajectory of agriculture and rural development in this country. It accentuates the increasing diversifi cation and hybridization of food production and consumption practices throughout history. With a framework that combines convention theory, neoinstitutional approaches and practice theory, this book suggests the concept of “food orders” which represents different arrangements of practices, institutions and sociotechnical artifacts. By exploring the interrelations between these elements, the book looks at six different food orders: industrial, commercial, domestic, aesthetic, civic and fi nancial, in tandem with examples of practices, sectors and territories to understand the dynamics of each one. This aids in understanding the main tendencies of the agrifood sector in such a vast country that, being a major player in global food markets, also affect production and consumption dynamics in several other countries. Besides, this book also seeks to comprehend the current institutional changes in Brazil that may be critical to interpret the global dissemination of populist and autocratic governments. Offering key insights into the contemporary sociology of agriculture and food, this book demonstrates how strengthening democracy and supporting the organization of civil society are major challenges when we think about transition for sustainable food systems.
