Book excerpt: Em relação às Mudanças climáticas os cientistas de 100 países que compõem o Painel Intergovernamental de Mudanças Climáticas (IPCC, 2007) concordam em que o aquecimento global já provoca mudanças no planeta. Segundo os relatórios, 1 bilhão de pessoas na Ásia são ameaçadas pelas secas ou enchentes e 175 milhões de crianças sofrerão todos os anos pela próxima década, 50 milhões a mais do que na última década. Embora o Brasil tenha uma matriz energética baseada em hidrelétricas, considerada mais limpa, o Brasil figura em 4º lugar entre os maiores emissores de gases estufa. O uso do fogo no sistema produtivo de cana-de-açúcar gera pontos negativos para a sociedade como um todo. As plantas utilizam a luz solar, através da fotossíntese, para fixar CO2 atmosférico numa vasta produção de biomassa, entretanto, ainda usamos uma pequena proporção desse carbono fixado para combustíveis, fibras e material de construção. A cana-de-açúcar (Saccharum officinarum L., família Poaceae), uma planta C4 altamente eficiente, pode armazenar cerca de 1% da luz incidente em biomassa por ano. Ultimamente, devido a três fatores – aumento da emissão de CO2, baixa reserva de petróleo e aumento dos custos. O álcool não contribui para agravar o efeito estufa, uma vez que a cana-de-açúcar, ao crescer, absorve o carbono emitido na queima do álcool

Available in PDF, EPUB and Kindle. Book excerpt: This edition of Evapotranspiration - Remote Sensing and Modeling contains 23 chapters related to the modeling and simulation of evapotranspiration (ET) and remote sensing-based energy balance determination of ET. These areas are at the forefront of technologies that quantify the highly spatial ET from the Earth's surface. The topics describe mechanics of ET simulation from partially vegetated surfaces and stomatal conductance behavior of natural and agricultural ecosystems. Estimation methods that use weather based methods, soil water balance, the Complementary Relationship, the Hargreaves and other temperature-radiation based methods, and Fuzzy-Probabilistic calculations are described. A critical review describes methods used in hydrological models. Applications describe ET patterns in alpine catchments, under water shortage, for irrigated systems, under climate change, and for grasslands and pastures. Remote sensing based approaches include Landsat and MODIS satellite-based energy balance, and the common process models SEBAL, METRIC and S-SEBS. Recommended guidelines for applying operational satellite-based energy balance models and for overcoming common challenges are made.
Book Synopsis Biofuels, Solar and Wind as Renewable Energy Systems by : D. Pimentel
Download or read book Biofuels, Solar and Wind as Renewable Energy Systems written by D. Pimentel and published by Springer Science & Business Media. This book was released on 2008-07-22 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: The petroleum age began about 150 years ago. Easily available energy has s- ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas s- plies have peaked and their supplies will slowly decline over the next 40–50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40–50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided by fossil energy, especially petroleum and natural gas, we appear to be slow to recognize the energy crisis in the U. S. and world. Serious energy conservation and research on viable renewable - ergy technologies are needed. Several renewable energy technologies already exist, but sound research is needed to improve their effectiveness and economics. Most of the renewable energy technologies are in uenced by geographic location and face problems of intermittent energy supply and storage. Most renewable technologies require extensive land; a few researchers have even suggested that one-half of all land biomass could be harvested in order to supply the U. S. with 30% of its liquid fuel! Some optimistic investigations of renewable energy have failed to recognize that only 0. 1% of the solar energy is captured annually in the U. S.

Download or read book Nitrogen Fixation written by and published by BoD – Books on Demand. This book was released on 2020-04-08 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation (BNF), the process by which gaseous N2 is converted into ammonia (NH3) via the enzyme nitrogenase, is crucial for the availability of nitrogen (N) in the terrestrial ecosystem. Some bacteria have the remarkable capacity to fix atmospheric nitrogen to ammonia under ambient conditions, a reaction only mimicked on an industrial scale by a chemical process. This microbiological process converts atmospheric nitrogen into a plant-usable form, thus decreasing the need to use chemical fertilizers in crop production. Chapters in this volume cover different aspects of this fantastic phenomenon, including biofertilizer, organic nitrogen in agricultural systems, nitrogen fertilization for sustainable crop production, and others. This book is designed for researchers, students and general readers.
Book Synopsis Sugarcane Bioethanol by : Luís Augusto Barbosa Cortez
Download or read book Sugarcane Bioethanol written by Luís Augusto Barbosa Cortez and published by . This book was released on 2010 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Brazil, sugarcane ethanol supplied, in 2009, 17.6 % of the energy for land transportation (excluding railroads)and about 55% of the total energy supplied by liquid fuel for Otto cycle engines. Besides the lower production costs ethanol produced from sugarcane in Brazil has another important advantage: in Central-South Brazil only 1 unit of fossil energy is used for each 8-9 units of energy produced by ethanol from sugarcane. Carbon emissions reduction also benefits from sugarcane ethanol: for each cubic meter of ethanol used as fuel, there is net saving of around 2 t CO2 not emitted to the atmosphere while, at the same time, no SO2 is emitted. Sugarcane was introduced in Brazil in 1532. The "Brazilian model" of producing concomitantly sugar and ethanol, brought important technical benefits and made possible an outstanding increase in the competitiveness in the international market for sugar and ethanol. Today about 50% of the sucrose of sugarcane produced in the country is directed to the production of sugar while another half is used to produce Ethanol. Industrial and academic R&D has helped to increase the productivity of ethanol steadily over the past 35 years, at a rate of 3.2% per year. Productivity gains implied savings of planted area by a factor of 2.6. In 2009/2010 the area planted with sugarcane for Ethanol production was 4.2 Mha, amounting to 1% of the total arable land available in Brazil. About 60% of the Ethanol produced in Brazil comes from the State of Sao Paulo, where the productivity is the highest (around 86 t/ha.year). Most of the recent expansion is happening in the center-west region of the country, in degraded pasture lands. The FAPESP Program for Research on Bioenergy, BIOEN, aims at articulating public and private R&D, using academic and industrial laboratories to advance and apply knowledge in fields related to ethanol production in Brazil. The BIOEN Program has a solid core for supporting academic exploratory research activities that will generate new knowledge and form scientists and professionals essential for advancing industry capacity in ethanol related technologies. On top of this, BIOEN includes partnerships with industry for cooperative R&D activities between industrial and academic laboratories, which are to be co-funded by FAPESP and industry.Federal agencies, such as CNPq, will also co-fund the research.

Book Synopsis The context of REDD+ in Mozambique: Drivers, agents and institutions by : Almeida Sitoe
Download or read book The context of REDD+ in Mozambique: Drivers, agents and institutions written by Almeida Sitoe and published by CIFOR. This book was released on 2012-01-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication offers an overview of REDD+ strategy in Mozambique through a synthesis of the current knowledge about the causes of forest carbon changes, a review of the legal and institutional context, and a description of the current political process of REDD+. The objective of the study is to collate data and relevant information, and to offer a preliminary analysis of the fundamental aspects that can help promote efficiency, efficacy, and equity in REDD+ policy. Specifically, this study concludes that some of the major problems for REDD+ in Mozambique are the lack of data about deforestation and forest degradation, institutional weakness (regarding monitoring and propriety rights), and gaps in human and technical capacity to fulfil demands associated with REDD+. Therefore, efficient results will depend on the degree to which REDD+ policies are oriented toward real mitigation of the sources of forest carbon changes. In Mozambique, REDD+ policy tends to originate outside the timber sector. The cost-effectiveness of the results will depend on identifying and addressing the fundamental causes of forest carbon changes through more viable REDD+ policy options; government capacity to respond to REDD+ demands, especially at the sub-national level; the capacity of civil society and other institutions; and the strength of the institutional framework. The degree of success of equitable outcomes and the generation of co-benefits will depend on the inclusion and appropriateness of the processes at the national level; if those who support REDD+ costs are also being compensated; and on the general definition of carbon rights and environmental services.
Book Synopsis Land-use trends and environmental governance policies in Brazil by : Andrew Miccolis
Download or read book Land-use trends and environmental governance policies in Brazil written by Andrew Miccolis and published by CIFOR. This book was released on 2014-12-29 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, the policy framework in Brazil has played a decisive role in shaping land use and changes in the rural landscape. Over the last three decades, the country has made impressive gains on socioeconomic, environmental and rural development policy fronts. Nonetheless, an overall analysis of Brazils policy framework pertaining to land use shows contradictions and constraints that need to be addressed in the long run. One such contradiction is given by disparities in rural credit and finance policies, with greater amounts favoring large-scale farming as opposed to family farming, despite the key role of smallholders in food production and job creation, and still low resources allocated to programs promoting low-carbon agricultural practices. Another contradiction is the dichotomy between climate change policies and mainstream agricultural and rural development policies. Brazils overriding challenge is harmonizing and effectively coordinating these different policy agendas at their various levels of implementation so as to effectively manage trade-offs. The question is what measures can be put in place to enable continued growth of agricultural production while also reducing its negative social and environmental costs? The answer lies partly in increasing support for implementing and up-scaling initiatives to promote low emissions agriculture and providing other economic incentives for adopting more sustainable use and conservation-oriented agricultural and land-use practices. Ultimately, reconciling agricultural production with conservation and rural livelihoods requires greater coordination and harmonization among sectoral policies at various levels of government. Achieving this goal requires the adoption of a combination of a value chain-based and territorial approach to land-use planning with more integrated farming systems in order to enable making improved decisions according to multiple trade-offs and impacts.

Book Synopsis Building a New Future by : United Nations
Download or read book Building a New Future written by United Nations and published by UN. This book was released on 2021-05-31 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication argues that Latin America and the Caribbean are in a position to move towards a "big push for sustainability" through a combination of economic, industrial, social and environmental policies capable of driving an equal and sustainable recovery and relaunching development in the region. Comprised of five chapters, the publication studies the three crises (slow growth, growing inequality and the environmental emergency) affecting economies and societies around the world, placing particular focus on those of Latin America and the Caribbean. It goes on to present a framework for analysing these crises in an integrated manner and measuring their magnitude in the specified regions. It then examines the quantitative impacts on growth, emissions, income distribution and the external sector under different policy scenarios, highlighting the potential of various policy combinations to forge a more dynamic growth path, with lower emissions and greater equality. Further identifying seven sectors that can drive sustainable development and proposing policies to foster these sectors, the publication concludes with an analysis that links up macroeconomic, industrial, social and environmental policies and the role of the State in building consensus for their implementation.

Book Synopsis Production of Ethanol from Sugarcane in Brazil by : Márcia Azanha Ferraz Dias de Moraes
Download or read book Production of Ethanol from Sugarcane in Brazil written by Márcia Azanha Ferraz Dias de Moraes and published by Springer Science & Business Media. This book was released on 2014-03-31 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of Brazil in the large-scale production and use of fuel ethanol has been widely discussed and analyzed by other countries interested in adopting policies designed to encourage the use of biofuels. Within this context, certain questions arise: Could the Brazilian experience be replicated in other countries? What were the conditions that enabled the creation of the Brazilian Proálcool (National Ethanol Program and what lessons can be learned? To examine these issues, it is important to understand the functioning of the key, interconnected markets (those for sugarcane, sugar and ethanol), which, from their inception, were the objects of extensive government intervention until 1999. Two main conditions enabled the creation of Proálcool: robust production of sugarcane and sugar (tightly regulated by the government, which applied the numerous regulations then in place); and the military regime that was in place at the time, whose decision-making and enforcement powers were quite broad, facilitating the carrying out of the necessary actions, as well as making it easier to coordinate the activities of the various stakeholders and sectors involved. This book increases understanding of the functioning of the sugarcane supply chain in Brazil, not only during the phase of government intervention but also in recent years (in the free-market environment). The lessons, positive and negative, gleaned from the Brazilian experience can contribute to reflection on and the development of alternative modalities of biofuel production in other countries, making the book of interest to scholars and policy-makers concerned with biofuel and renewable resources as well as economic development.
