Sustainability of Irrigation Fruit Farming in Terms of Water Supply-demand Situation: Case Study of the Middle Basin of São Francisco River, Northeast Brazil

The objective of this study was to evaluate the input of suspended sediment from the slope toe in the São Francisco River channel, in Northeast Brazil, under different soil bioengineering techniques. Sediments were collected in the years of 2013, 2014 and 2015, in five transects crossing the river channel. Sediment input in the sampling points was higher in the year of 2013, i.e., the year of the highest river discharge. Sediment supply to the river channel for a period of 3 years (2013, 2014 and 2015), was evaluated at 20, 40 and 60% depth, along five different transects (P1= riverbank, P2= beginning of the thalweg, P3= middle of the thalweg, P4= end of the thalweg, and P5 = margin of the side sandybar), oriented by the presence or absence of erosion control techniques (treatments) such as: 1-Natural Vegetated Slope; 2-Vegetated Riprap; 3-Eroded Slope; 4-Live Cribwall and 5-Vetiver grass Contour Line. Sediments input was different in all evaluated transects, and the one identified as Eroded Slope at 20% depth presented the lowest amount of suspended sediment load. There was a decrease in the total amount of suspended sediment in the evaluated periods, probably due to the progressive decrease in the river discharge, and the protection provided by the soil bioengineering techniques.

Resumo: O artigo analisa as comemorações do centenário de Delmiro Gouveia, ocorridas em 1963. Considerado um mártir na luta contra brasileira o capital estrangeiro, o empreendedor pioneiro no aproveitamento do potencial hidrelétrico do rio São Francisco e o modernizador dos sertões alagoanos, Delmiro foi retomado como um ácone nacionalista num contexto em que se discutiam os rumos para o desenvolvimento do Nordeste. As comemorações do seu centenário de nascimento, ocorridas em Pernambuco, envolveram esforços para atribuir ao ”coronel dos coronéis” o epáteto de pioneiro na redenção regional. As diversas atividades constituintes destas celebrações revelam um embate não só pela confecção da memória do homenageado, bem como uma tensão entre transformá-lo em um herói nacional e utilizar a sua biografia para acentuar as particularidades do povo nordestino. Neste texto, o alvo das atenções é a ”Semana Delmiro Gouveia” (SDG), organizada pelo Instituto Joaquim Nabuco de Pesquisas Sociais (IJNPS), localizado no Recife, Pernambuco. Ali estiveram reunidos alguns dos principais estudiosos de Gouveia que, sob a coordenação de Gilberto Freyre e Mauro Mota, apresentaram as suas interpretações sobre a vida e a obra do ”Coronel dos Coronéis”. Palavras-chave: Delmiro Gouveia, Comemoração, Nordeste Brasileiro. THE CITY OF RECIFE AND THE DELMIRO GOUVEIA CENTENARY IN PERNAMBUCO (1963)Abstract: This article analyzes the centenary celebrations of Delmiro Gouveia, occurred in 1963. Considered a martyr in the fight against Brazilian foreign capital, the pioneering entrepreneur in harnessing the hydropower potential of São Francisco River and the modernizing of Alagoas backwoods, Delmiro was included as a nationalist icon in a context in which they discussed the directions for the Northeast development. The celebrations of his centenary birth, occurred in Pernambuco, had involved efforts to give him the epithet pioneer in regional redemption. The various constituent activities of these celebrations reveal a clash not only by creation of the honoree's memory as well as a tension between turn it into a national hero and use his biography to emphasize the particularities of the northeastern people. This paper is mostly about the "Delmiro's Gouveia Week", organized by the Institute for Social Research Joaquim Nabuco, located in Recife, State of Pernambuco. In this place gathered some of the leading scholars of Gouveia, who, under the coordination of Gilberto Freyre and Mauro Mota, presented their interpretations of the life and work of biggest colonel in Brazilian history. Keywords: Delmiro Gouveia , Celebration, Northeast Brazil.

Transport Modes

With the beginning of unconventional exploration and exploitation of natural gas in Brazil, the question of how to transport the product is concerned. Being the transport an essential part to supply energy to consumers, to move towards energy efficiency one should seek sustainability in the logistic process from the production until delivery at final destination. The objective of this study is the regional assessment of two transport modes for natural gas: by pipeline or as secondary energy in the form of electricity. Since society no longer accepts development at any cost, to determine the best mode of transport three other factors have been added to the techno-economic factor, which are environmental and social impacts, and political risks, defining specific methods to internalize externalities. The full cost analysis considers the four factors under a balanced importance degree for planning towards sustainability. A case study deals with the energy transport (natural gas and electricity) to meet consumer markets in the state of Minas Gerais, between exploratory gas fields at Sao Francisco river basin. The research method employs the most relevant elements of analysis within the four dimensions, assigning specific valuations according to transport mode particularities and providing the best product transportation mode. To attend the region demand for energy, full cost analysis points to energy transport in the form of electricity as the best alternative.

This paper describes Sporolithon franciscanum, a new rhodolith-forming species of non-geniculate coralline algae found at depths between 47–52 m near the São Francisco river mouth, the second largest and the most extensive drainage basin in Brazil, and also at the Abrolhos Bank, in the world´s largest rhodolith beds. DNA sequences from plastidial psbA and rbcL markers indicate that the species is unique compared to all other Sporolithon species that have thus far been sequenced. Since morpho-anatomical features of the new species are shared with some other Sporolithon species, its identification was only confirmed by DNA sequences.
