In recent years, wind power in Brazil has emerged as an alternative to diversify the country′s energy mix and minimize the emission of pollutants derived from fossil fuels. The state of Rio Grande do Norte, in the Brazilian Northeast, has considerable potential for the generation of wind energy due to the occurrence of strong winds in many areas along the coast and in the interior of the state, in places with higher altitudes. However, wind energy, despite being considered clean and renewable, can cause environmental impacts in those places. Thus, the present study analyzed the perception of environmental impacts caused by the installation of wind farms in the agricultural areas of Northeast Brazil. The study was carried out in the municipality of Serra do Mel, in the western region of the state of Rio Grande do Norte, based on a survey of local farmers. The study concluded that farmers live without major problems and without apparent conflicts with wind farms but have little knowledge about the environmental impacts. In the perception of most farmers, there are few negative environmental impacts, and those that exist are barely noticed or still do not cause damage to most farmers in the region.

Wind energy has many advantages compared to traditional energies, from the ability to reduce the use of fossil fuels as well as the possibility of creating jobs in the areas where the projects are installed. The growth of this type of generation in Brazil has been driven by strong investor interest due to the characteristics of the country's winds, mainly from the Northeast. The winds are strong, stable and most of the time follow the same direction, characteristics that make windfarms in the Northeast region have high levels of capacity factor. By evaluating the data from the wind farms installed in Ceará, it can be observed that they present one of the best capacity factors in Brazil and have values above the world average. This indicates and reinforces the viability of implementing this type of energy generation in the area. It was verified that there are studies about wind conditions but there are no studies that correlate this information with the infrastructure conditions of the State. Therefore, the objective of the present work is to identify the appropriate areas for the allocation and use of wind energy in the State of Ceará through the integration of Geographic Information Systems (GIS) tools and multicriteria analysis for decision making.

This study provides the first record of the exotic invasive bivalve Isognomon bicolor for the State of Paraíba, Northeastern Brazil. It has been found to occur in at least twelve coastal reefs along the coast. We also present its first record for the State of Alagoas and new record localities for the States of Rio Grande do Norte and Pernambuco, including its occurrence in hypersaline estuaries. From these records the distribution range of I. bicolor has been expanded to the littoral region of Northeast Brazil, where this invasive species seems well established.

Offshore wind farms in deep water are becoming an attractive prospect for harnessing renewable energy and reducing dependence on fossil fuels. One area of major concern with offshore wind turbines is stability control. The same strong winds that give deep water turbines great potential for energy capture also pose a threat to stability, along with potentially strong wave forces. We examine development of state space controllers for active stabilization of a spar-buoy floating turbine. We investigate linear state feedback with a state observer and evaluate response time and disturbance rejection of decoupled SISO controllers.

The Washington Department of Fish and Wildlife (WDFW) adopted wind power guidelines in 2002 to promote standardisation of the agency's responses to proposed wind energy projects in Washington State. While the purpose of the guidelines was to create consistency from the agency, some of the recommendations seemed overly stringent and unjustified to the wind industry. Recognising the implications of the guidelines on wind energy development in the State, the Renewable Northwest Project (RNP), along with industry members and their permitting consultants, successfully engaged the agency in a discussion to reach fair and consistent wind power guidelines. The account and methods of negotiation are detailed as an example for abating possible adverse avian and habitat environmental impact of wind farms. The three key areas of negotiation were: pre-permit environmental studies, wildlife and habitat mitigation, and an alternative fee-based mitigation option.

Energy produced through biomass, when produced in an efficient and sustainable way, generates a series of environmental, economic and social benefits when compared to the use of fossil fuels. Benefits such as better land management, job creation, efficient use of agricultural areas, provision of modern energy vectors to rural communities, reduction of CO2 emissions, waste control and nutrient recycling can be highlighted. This paper discusses the contributions of energy co-generation, from biomass, to the supplementation of electric energy, reduction of environmental impacts and generation of employment. The aim was to understand the impact of public policies to increase the efficiency of the sugar-energy sector and if there was an increase in employment and manpower in the field, as well as reduction of environmental impacts by reducing the consumption of other less renewable sources of energy within the State from São Paulo. In order to carry out this study, it was necessary to analyze the social, economic and agronomic indicators and the energy plans that aim at the development of the sector, such as the National Energy Plan and the Paulista Energy Plan.

AbstractRecent sociological analysis of the expansion of the biofuels industry internationally has noted the paradox between the purported global environmental benefits of reducing greenhouse gas emissions by replacing fossil fuels with biofuels, and the potential for distinctly negative environmental impacts experienced at local sites of biofuels production. The state, in both the USA and the EU, has played a prominent role in promoting the development and expansion of biofuels production through government mandates and incentives, but the state's role in governing the potentially (negative) economic, social or environmental impacts of biofuels production on local communities has been much more limited in scope. We review the environmental sociological literature to frame analysis of how the state is governing the benefits and burdens brought by the ethanol industry to rural communities in Kansas and Iowa. Drawing on data from community surveys, focus group and individual interviews and analysis of environmental violations, the paper examines the local impacts of biofuels production in three case-study communities. Findings suggest that local residents do not express many concerns about environmental impacts and that the state has played a modest role in governing the negative local environmental impacts. We argue that this lack of concern is related to the histories of these rural communities, which have long depended on resource extractive industries and currently are desperate for economic growth. We find that criticisms of negative environmental impacts are muted in relation to purported economic benefits and to other comparable industries. These community case studies illustrate some of the challenges, both at the practical and theoretical levels, of governing biofuels production.

Seaweed is a source of multipurpose bioresources, providing millions of dollars to the world’s economy and performing various ecosystem services that aid in maintaining marine balance, reducing eutrophication, providing nutrients and mitigating atmospheric CO2. In this context, this study aims to evaluate the potentialities of the cultivation of the Crassiphycus birdiae seaweed on the eastern coast of the state of Rio Grande do Norte (RN), Brazil, considering the physical and environmental aspects. Estimates concerning suitable areas and their productive potential for the Biomass, Bioethanol, Biofertilizer and Agar bioproducts were carried out. These estimates were based on the Modular Ferry System (MFS) installed on the state coast. Suitable cultivation areas were determined by applying an Analytic Hierarchy Process (AHP) and change detection analysis based on physical and infrastructure factors, such as areas sheltered by winds, sea currents and waves, proximity to seaweed banks, road infrastructure and socioeconomic and environmental factors. Areas identified as suitable for seaweed cultivation totaled 2227.59 ha in area, with a productive potential of 195 thousand tons of fresh biomass/year, over two million liters of ethanol/year and about 43 tons of agar/year. These findings demonstrate that the northeastern coast of Brazil has the potential to generate employment and income through seaweed cultivation, stimulating the coastal region’s development in a sustainable manner.

Em meados do século XIX, a articulação sistematizada do território da nação brasileira foi formulada como ponto-chave para a estruturação da economia e da sociedade modernas. Esse intento ultrapassava as antigas demandas de controle geopolítico e encontrou nas estiagens prolongadas nas “províncias do norte” um sério problema. Falar de nova estrutura territorial pressupõe indagar: que conhecimentos e informações iconográficas sobre o território em reorganização tinham aqueles que adentraram no “Brasil desconhecido”? Discutir pertinências e limites do uso das fontes cartográficas como documentos que permitam compreender as ações sistematizadas sobre o território nordestino é o objetivo deste artigo. Para tanto, privilegiar-se-á o “Atlas do Império do Brazil”, organizado por Cândido Mendes de Almeida, em 1868, com ênfase nas províncias mais atingidas pelas secas: CE, RN, PE e PB. O Atlas é lido assim dentro da trama de relações da formação da cultura técnica moderna no Brasil e, mais especificamente, dos processos que levariam à definição da região Nordeste. Palavras-chave: atlas; Cândido Mendes; cultura técnica; Império; reconfiguração territorial; Nordeste/Brasil. Abstract: In the mid-nineteenth century, the systematic articulation of Brazilian territory was formulated as an essential issue to forge modern economy and society. This attempt overcame old geopolitical control demands and delineated long-term droughts in “northern provinces” as one of the major problems. Thus, it is fundamental to investigate which knowledge and cartographical information were handled by those who went upon “unknown Brazil”. This article aims to analyze the limits of cartographical sources as historical documents to comprehend planned and systematic actions on the territory of Brazilian Northeast. For this analysis, we focus on the “Atlas do Império do Brazil” [Atlas of Brazilian Empire], edited by Cândido Mendes de Almeida, in 1868, emphasizing the provinces of Ceará, Rio Grande do Norte, Pernambuco and Paraíba, the most affected by the climate phenomena. The Atlas may be understood, therefore, as part of the arena of relationships which developed modern technical culture in Brazil and, more specifically, as part of the processes that lead to the definition of Northeast as an official region. Keywords: atlas; Cândido Mendes; technical culture; Empire; territorial reconfiguration, Northeast/Brazil.
