What is river basin revitalization’s place in relation to water security? This question is the basis of our reflection, posed to help in the understanding of the evolution of both concepts, taking management of the São Francisco River Basin (Brazil) as a case study. With this main objective in mind, a literature review was carried out, followed by the collection of survey data on the watershed’s revitalization program. In this context, the members of the São Francisco River Basin Committee (a total of 124 participants) were consulted, using questionnaires with the Delphi method. The respondents (a total of 47) chose the river basin revitalization strategy as the main measure to achieving water security in the São Francisco River Basin. They also highlighted the importance of the environmental dimension, underlining measures for conservation and restoration of the ecosystem’s natural functions. The concept map tool was adopted for a comparative perspective between conceptual implications of revitalization and water security for the studied river basin’s conservation. The results showed the existence of a symbiotic relationship between both concepts. Consequently, we conclude that it is urgent to reconcile water use and ecosystem ecological integrity through the comprehensive concept of water security.

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.

AbstractThis paper presents a linked hydro-economic model and uses it to examine the regional effects of water use regulations and product price changes on the agriculture of the São Francisco River Basin, Brazil. The effects of weather on surface water availability are explicitly addressed using the hydrological model MIKE-Basin. Farmers’ adjustments to changes in precipitation, surface water availability, and other factors are quantified using an economic model based on non-linear programming techniques. The models are externally linked. Results show that regional impacts, at the sub-basin level, vary depending on the location of each sub-basin relative to river flows. The effects of water use regulations and of exogenous price shocks on agriculture depend on weather, location, product mix and production technology. Implications of these results for policies designed to manage agriculture and water use are discussed.

Despite advances in water resources management and planning, the São Francisco River Basin in Brazil has suffered from systematic drought problems in recent years, leading to severe human and environmental water security threats. This paper aims to track the water security for different periods and its relations with the changes in physical and natural asset conditions. The paper explores how investment planning to mitigate the water security threats and explore opportunities to increase the value of investments. The paper finds that grey infrastructure has regulated threats from increasing in the downstream of the river basin, however, continuous increase in water security threats in the upstream of the basin threatens water security downstream. This is evident from the spatial connectivity and unidirection externalities. As the capacity to further increase in grey investment is reaching its limit in the downstream, the increases in green infrastructure investment upstream, especially in the Grande River basin, could be one the way to reduce the externalities and minimise the water security risks.

AbstractIn recent years, it has become popular for some of countries and regions to adapt the system of governance to varied and complex issues concerned with regional development and the environment. Watershed management is possibly the best example of this. It involves flood control, water use management and river environment simultaneously. Therefore, comprehensive watershed-based management should be aimed at balancing those aims. The objectives of this study are to introduce the notion of environmental governance into the planning process, to establish a method for assessing the alternatives and to develop a procedure for determining the most appropriate plan for environmental governance. The planning process here is based on strategic environment assessment (SEA). To verify the hypothetical approach, the middle river basin in the Tokachi River, Japan was selected as a case study. In practice, after workshop discussions, it was found to have the appropriate degree of consensus based on the balance of flood control and environmental protection in the watershed.

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)

A total of 103 specimens of Hoplias intermedius (Günther, 1864) and 86 specimens of H. malabaricus (Bloch, 1794) from the upper São Francisco River, State of Minas Gerais were collected between April 2011 and August 2013, and their parasitic fauna were investigated. Four species of Digenea were found: metacercariae of Austrodiplostomum sp., and Ithyoclinostomum sp.; and adult specimens of Phyllodistomum spatula Odhner, 1902, and Pseudosellacotyla lutzi (Freitas, 1941) Yamaguti, 1954. The prevalence of the metacercariae was higher than that of the adult digeneans of erythrinids from the upper São Francisco River as a result of piscivorous feeding habits of these adult erythrinids. The presence of metacercariae and adult digeneans indicate that they act as intermediate and definitive hosts, respectively, in their biological cycles. Hoplias intermedius is a new host for the four species of Digenea, and the São Francisco River basin is a new location for the known geographical distributions of P. spatula and P. lutzi.
