Introduction: The São Francisco River Basin Committee (CBHSF) was set up by presidential decree in 2001 with the aim of achieving decentralized and participatory management of its water. The São Francisco River flows overland for 2700 km from its source in the Serra da Canastra (MG) to its mouth between Sergipe (SE) and Alagoas (AL). The river passes through the states of Bahia (BA), Pernambuco (PE), Goiás (GO) and the Federal District (DF). Central to the discussion in this research on the transposition of the São Francisco River is question of conflict concerning water management in the São Francisco River Basin Committee, making a nonsense of its power to function, contrary to the project, and the Federal Government which initiated the work and approved the budget. Hence, this study aims to analyze water management in the São Francisco river basin from the initiation of the CBHSF in order to understand how approval of the project and implementation of the work ran against the statutory representation of the committee. Methodology and Development: Having a qualitative approach, the study will be divided between theoretical research based on authors who study the topic of water and its transformation into a water resource and the major landowners of the north-east semi-arid zone in the context of transposition; the dynamics and politics of the river basin; as well as the role of the river basin committees in the process of decentralizing Brazilian water management, specifically concerning the São Francisco River and its state and interstate committees. Documentary research will take into account National Water Resources Law 9.433/1997; state water policies; documentary archives of the river basin committees (state and interstate), as well as the agencies participating in the integration project, such as the National Water Agency (ANA), the Integration Ministry (MI), and the Environment Ministry (MMA). Further data will be obtained using the transcripts of semi-structured interviews with presidents of the river basin committees as well as visiting transposition works and attending CBHSF meetings. Final thoughts: The transposition of the São Francisco River demonstrates how the legacy of Brazilian governmental centralization policies holds back the participatory process of the river basin committees, encroaching on their legal and institutional positions as regards water in the north-east semi-arid zone amid the persistence of drought.

This work evaluated dry and rainy conditions in the subregions of the São Francisco River Basin (BHSF) using the Standardized Precipitation Index (SPI) and Markov chains. Each subregion of the BHSF has specific physical and climatic characteristics. The data was obtained from the National Water Agency (ANA), collected by four pluviometric stations (representative of each subregion), covering 46 years of data, from 1970 to 2015. The SPI was calculated for the time scales of six and twelve months and transition probabilities were obtained using the Markov chain. Transition matrices showed that, at both scales, if the climate conditions were severe drought or rainy, switching to another class would be unlikely in the short term.  Correlating this information with the probabilities of the stationary distribution, it was possible to find the regions that are most likely to be under rainy or dry weather in the future. The recurrence times calculated for the stations that belong to the semi-arid region were smaller when compared to the value of the return period of the representative station of Upper São Francisco that has higher levels of precipitation, confirming the predisposition of the semi-arid region to present greater chances of future periods of drought.

SummaryThe São Francisco River provided very obvious, close-by forms of sustenance for local communities. Beginning in the mid-1950s, the river became the place for large hydro-electric facilities, large-scale flooding, and population resettlement. A decade later, the federal government began working on pilot irrigation projects that would lead to areas described today as the Brazilian California. Hydro-power for Brazilian cities such as Recife and Salvador and irrigation for grapes and mangoes destined for the United States and Europe are among the eco-system services this river supplies. The purpose of federal policies for the north-east went beyond mitigation of the consequences of droughts, the hydraulic approach, and started to follow an economic approach based upon development; as a consequence, river and user came to be distant from one another. The two major intensive uses of the river, electricity and irrigation, threaten the long-term sustainability of this system.

Corbicula largillierti is a native mollusk from China. In Brazil, this species was first recorded in the Pantanal of Mato Grosso. This short communication reports the occurrence of C. largillierti for the first time in the Paraíba river basin (Brazilian semi-arid), and also considers the risk of introduction of other molluscs invaders in this basin due to the diversion of water from the São Francisco River. Densities of individuals ranged from 33 to 65 ind.m-2 (maximum values of 484 ind.m-2) in coarse sediment (gravel, 2-4 mm). The diversion of waters from the São Francisco river can lead to the introduction of new species, enhancing ecological problems in the Paraiba river basin.

Introdução: A presente pesquisa teve como objetivo compreender o desenvolvimento do agronegócio e seus impactos, no que diz respeito à dinâmica geográfica do trabalho, nas principais regiões de expansão da fruticultura no sertão nordestino. A expansão do capital, sob o modelo do agronegócio, no Nordeste do Brasil, tem propiciado inúmeras alterações na dinâmica socioespacial, cuja expressão nos territórios ganha corpo a partir da mobilização promovida pela divisão social e territorial do trabalho. Como resultado, testemunhamos o surgimento de um novo padrão de desigualdades sociais, evidenciando o conteúdo dos conflitos territoriais envolvendo agentes transescalares, tais como os supermercados e empresas multinacionais, bem como trabalhadores organizados em sindicatos e em movimentos sociais de luta pela terra e pela água. Metodologia/Desenvolvimento: A metodologia foi estruturada em torno de três eixos de operacionalização: a organização de uma pesquisa bibliográfica, a construção de um banco de dados estatísticos vinculados à elaboração de uma matriz metodológica e a realização de trabalhos de campo. Considerações finais: A partir da organização da rede de produção global de frutas verificou-se o papel central de novos agentes econômicos, com especial atenção para as redes varejistas (supermercados) e sua grande influência na comercialização de frutas junto aos produtores, bem como por suprir o consumo das mesmas no mercado externo. As repercussões do consumo nas regiões de produção e consequentemente na dinâmica geográfica do trabalho vão desde a ampliação dos conflitos de terra, a exclusão dos pequenos produtores dos canais de comercialização, a intensificação do trabalho com o intuito de garantir a sustentação da política de preços (guerra dos descontos), passando pelas mudanças no processo produtivo a partir das exigências dos consumidores. Como corolário, apontamos o papel dos supermercados e sua atuação no controle e governança da produção a partir da mercadificação dos sistemas de auditoria e certificação. Nas regiões analisadas, identificamos a criação recente de um mercado de trabalho formal no setor da agropecuária marcado pela sazonalidade dos vínculos empregatícios e pela ocorrência de inúmeros conflitos envolvendo exploração dos trabalhadores como as extensas jornadas, os casos de coação, assédio moral e sexual no ambiente de trabalho; o aumento no número de doenças, acidentes de trabalho e a contaminação por agrotóxicos dos trabalhadores e do meio ambiente. No que diz respeito à organização dos trabalhadores, a representação dos sindicatos é contestada em virtude da existência de entidades descoladas das demandas dos trabalhadores assalariados e dos diaristas informais. Os movimentos sociais, com muitas dificuldades, têm contribuído para engendrar pautas de luta e reivindicação, bem como possibilitar a conquista da terra e de novas práticas de trabalho em espaços como os assentamentos, acampamentos, comunidades ribeirinhas e terras tradicionais de uso coletivo.

The Chingandzha flora comes from the volcanic-sedimentary deposits of the Chingandzha Formation (the Okhotsk-Chukotka volcanic belt, North-East of Russia). The main localities of the Chingandzha flora are situated in the Omsukchan district of the Magadan Region: on the Tap River (basin of the middle course of the Viliga River), on the Kananyga River, near the mouth of the Rond Creek, and in the middle reaches of the Chingandzha River (basin of the Tumany River). The Chingandzha flora includes 23 genera and 33 species. Two new species (Taxodium viligense Golovn. and Cupressinocladus shelikhovii Golovn.) are described, and two new combinations (Arctopteris ochotica (Samyl.) Golovn. and Dalembia kryshtofovichii (Samyl.) Golovn.) are created. The Chingandzha flora consists of liverworts, horsetails, ferns, seed ferns, ginkgoaleans, conifers, and angiosperms. The main genera are Arctop teris, Osmunda, Coniopteris, Cladophlebis, Ginkgo, Sagenoptepis, Sequoia, Taxodium, Metasequoia, Cupressinocladus, Protophyllocladus, Pseudoprotophyllum, Trochodendroides, Dalembia, Menispermites, Araliaephyllum, Quereuxia. The Chingandzha flora is distinct from other floras of the Okhotsk-Chukotka volcanic belt (OCVB) in predominance of flowering plants and in absence of the Early Cretaceous relicts such as Podozamites, Phoenicopsis and cycadophytes. According to its systematic composition and palaeoecological features, the Chingandzha flora is similar to the Coniacian Kaivayam and Tylpegyrgynay floras of the North-East of Russia, which were distributed at coastal lowlands east of the mountain ridges of the OCVB. Therefore, the age of the Chingandzha flora is determined as the Coniacian. This flora is assigned to the Kaivayam phase of the flora evolution and to the Anadyr Province of the Siberian-Canadian floristic realm. The Chingandzha flora is correlated with the Coniacian Aleeky flora from the Viliga-Tumany interfluve area and with other Coniacian floras of the OCVB: the Chaun flora of the Central Chukotka, the Kholchan flora of the Magadan Region and the Ul’ya flora of the Ul’ya Depression.

The article continues the author's research on the toponymy of the North-East of the Sakha Republic, in particular the Kolyma river basin, in the aspect of the interaction of related and unrelated languages. The relevance of this work is defined in the description of local geographical terminology of Yukagir origin, as a valuable and important material in the further study of toponymy of the region. For the first time, the toponymy of the Kolyma river basin becomes the object of sampling and linguistic analysis of toponyms with local geographical terms of Yukagir origin in order to identify and analyze them linguistically. The research was carried out by comparative method, word formation, structural, lexical and semantic analysis. As a result of the research, phonetic and morphological features are revealed, the formation of local geographical terms and geographical names of Yukagir origin is outlined, and previously unrecorded semantic shifts and dialectisms are revealed. The most active in the formation of terms and toponyms is the geographical term iилil / eҕal 'coast‘, which is justified by the representation of the Yukagirs’ coast' home, housing

In Austria approximately 70% of the population is connected to sewerage and to biological waste water treatment plants. Whereas the urban areas are already provided with these facilities to a very high extent, effort is still needed in rural areas to meet the requirements of the Austrian legislation. The way, this task should be solved has provoked much controversy. It is mainly the question, whether centralised or decentralised sewage disposal systems are preferable from the ecological and economical point of view, that became a political issue during the last 5 years. The Institute for Water Quality and Waste Management was asked to elaborate a waste water management concept for the Lainsitz River Basin, a mainly rural area in the north of Austria discharging to the Elbe river. Both ecological and economical aspects should be considered. This paper presents the methodology that was applied and the criteria which were decisive for the selection of the final solution.

Abstract The main objective of this research paper is to assess the extent to which the concept of water accounting has been applied for water management at the river basin scale in India. For this, the study first assesses the importance given to the use of water accounting for water management in India's national water policy. It then analyses the evolution of water accounting approaches in India through a systematic review of the past research studies on the theme. Further, it looks at their contribution to decision-making concerning allocation of water resources and resolving conflicts over water sharing. Finally, it identifies the existing gaps in the methodologies for water accounting so far used in India.

Rhinelepis aspera is the largest Loricariidae species found in the São Francisco river basin where it is now rarely caught. Brooders kept in tanks were hypophysed with crude carp pituitary extract (CCPE). Approximately 82% of the females responded positive to the treatment. The egg was opaque, demersal, round, yellow and adhesive. Egg stripping was done at 212 hour-degrees (= 8.2 h) after application of the second dose of CCPE (water temperature = 25-26 ºC). Hatching of the larvae occurred at 1022 hour-degrees (= 42.2 h), after fertilization of the eggs (water temperature =24-25 ºC). Fertilization rate of the eggs was 72%. Absolute fecundity (AF), initial fertility (IF) and final fertility (FF) in relation to the females' body weight are expressed, respectively, by the equations: AF = - 33993 + 122308 Wt (r² = 0.88), IF = - 14823 + 58619 Wt (r² = 0.71) and FF = - 6553 + 29741 (r² = 0.61)
