A água de chuva como potencial para aumentar a disponibilidade hídrica no semiárido brasileiro. Infoteca-e
BRITO, L. T. de L..
A Embrapa, historicamente, tem disponibilizando tecnologias e conhecimentos como estratégia para a inovação e desenvolvimento da agricultura do Semiárido brasileiro, a partir de uma melhor compreensão sobre os seus recursos naturais. Com objetivos afins, as organizações sociais desta região estabeleceram canais de interlocução entre o governo e a sociedade para juntos enfrentarem o desafio de ampliar a oferta de água para atender às demandas de consumo humano, como também reduzir os riscos de segurança alimentar das famílias rurais diante da instabilidade climática regional, por meio do Programa Cisternas. A implantação desse programa teve como premissa a temática do aproveitamento da água de chuva, preconizada há quase quatro décadas em ações de pesquisa...

Análisis de alternativas para la eliminación de la sobreexplotación de acuíferos en el Valle de Guadalentín AgEcon
Calatrava-Leyva, Javier; Guillem, Amanda; Martinez-Granados, David.
In this paper we analyse the economic impact of alternative water management instruments that allow addressing the problem of non-renewable groundwater pumping in the aquifers of the Guadalentín Valley (southeast Spain). Their impact is assessed using a partial equilibrium mathematical programming model that maximises the farm net margin resulting from the use of the available water resources for irrigation in the area. Our results show that the buyback of groundwater pumping rights is the option with the greatest public budgetary cost and economic impact. On the contrary, the combination of an environmental tax on groundwater pumping and the substitution of groundwater by subsidised desalinised water allow eliminating aquifer overdraft in the area while...

Are Agricultural Measures for Groundwater Protection Beneficial When Compared to Purification of Polluted Groundwater? AgEcon
Hasler, Berit; Lundhede, Thomas.
The groundwater resource, the drinking water areas and the surface water quality can be protected by measures, e.g. by reductions of pesticide and nutrient applications, conversion of arable land to grasslands or forests etc. The objective of the paper is to estimate the benefits of groundwater protection by the valuation method choice experiments. This method allows for separate estimation and comparison of the different attributes connected to groundwater protection i.e. the effects on drinking water and surface water quality as compared to the benefits from cleaning and treatment of polluted drinking water to make it suitable for drinking water consumption. The results indicate that the benefits are significant, and that the willingness to pay for...

Assessing groundwater potential use for expanding irrigation in the Buriti Vermelho watershed. Repositório Alice
WENDT, D. E.; RODRIGUES, L. N.; DIJKSMA, R.; VAN DAM, J. C..
A demanda por alimentos no Brasil cresceu substancialmente devido, entre outras coisas, ao aumento da classe média. O Cerrado brasileiro é um dos poucos lugares no país onde a agricultura ainda pode expandir e atender a essa nova demanda, sem comprometer o meio ambiente. A região do Cerrado possui duas estações climáticas bem definidas, uma seca e outra chuvosa. O longo período da estação seca, que vai de maio a setembro, contribui para o surgimento de vários problemas, entre eles restrições hídricas, conflitos e insegurança na produção de alimentos. Sem irrigação, apenas dois plantios podem ser feitos por ano. Os cultivos sofrem com os veranicos e a produção é incerta. A irrigação é de fundamental importância nesse contexto, mas sua expansão é limitada...

Assessment of the origin of microbiological contamination of groundwater at a rural watershed in Chile Agrociencia
Valenzuela,Mariela; Mondaca,María A.; Claret,Marcelino; Pérez,Claudio; Lagos,Bernardo; Parra,Oscar.
In a rural watershed in Chile, the scarce groundwater available represents almost the only water source both for agriculture and domestic use. This water has microbiological quality problems, which result in an agricultural and local economic development constraint. Contamination can come from punctual or diffuse sources. Characterizing the microbiological quality of groundwater allows both to identify sources from the point of view of whether they are point or non point -thus facilitating their reduction or elimination- and to determine health hazards likely to affect the population in the area under study. This study aimed to improve the state of knowledge on the microbiological quality of groundwater at a rural watershed. Forty two wells were seasonally...

Bacteria and protozoa populations in groundwater in landfill area in São Carlos, SP Rev. Microbiol.
Fusconi,Roberta; Godinho,Mirna Januária Leal.
The microbial populations of groundwaters were analyzed in a region under the influence of a landfill (piezometer L12) in the town of São Carlos, São Paulo, Brazil, and in an area not influenced by the landfill (piezometer L5). Heterotrophic bacteria were counted by spread plate method and the number of protozoa was estimated by the most probable number method. There was a larger number of organisms in well L12, with a mean value of 15.76 x 104 CFU/ml for bacteria and 9.7 MPN/ml for protozoa, whereas the mean values for piezometer L5 were 2.88 x 104 CFU/ml for bacteria and 3.4 MPN/ml for protozoa. The greater abundance detected in piezometer L12 may be related to the influence of the leachate through the landfill on the microbial populations, also...

Detection of Cryptosporidium sp. oocysts in groundwater for human consumption in Itaquaquecetuba city, S. Paulo-Brazil BJM
Gamba,Rosa de Carvalho; Ciapina,Elisa Mara Prioli; Espíndola,Rodrigo S.; Pacheco,Alberto; Pellizari,Helena.
Cryptosporidium is an emergent pathogen that causes profuse diarrhea in humans. Outbreaks of human cryptosporidiosis have implicated water as a possible source of contamination. In this study the presence of Cryptosporidium sp. oocysts was investigated as well as the fecal contamination in groundwater for consumption in Itaquaquecetuba - São Paulo. Therefore, it was possible to notice that the septic tanks were located close to the wells, exposing them to risk of contamination. As a consequence of these results and observations efficient disinfecting practices and groundwater monitoring are recommended.

Development of private insurance schemes as a means to reduce water overexploitation during drought events. A case study in Campo de Cartagena (Segura River Basin, Spain) AgEcon
Perez Blanco, Carlos Dionisio; Gomez Gomez, Carlos Mario.
Water is a key input in the production of many goods and services and under certain conditions can become a critical limiting factor with significant impacts on regional development. This is the case of many agricultural European Mediterranean basins, where water deficit during drought events is partially covered by illegal abstractions, mostly from aquifers, which are tolerated by the authorities. Groundwater overexploitation for irrigation has created in these areas an unprecedented environmental catastrophe that threatens ecosystems sustainability, urban water supply and the current model of development. Market-based drought insurance systems have the potential to introduce the necessary incentives to reduce overexploitation during drought events and...

Diagnóstico dos poços tubulares profundos e da qualidade das águas subterrâneas no município de Concórdia, SC. Repositório Alice
MATTHIENSEN, A.; COMASSETTO, V.; ALVES, J.; FAVASSA, C. T. A.; WASKIEWIC, M. E.; BÓLICO, J..
O presente trabalho apresenta um diagnóstico dos poços tubulares profundos e da qualidade das águas subterrâneas do município de Concórdia, localizado na região meio-oeste de Santa Catarina, Brasil. Foram cadastrados 686 poços no município, distribuídos numa área de cerca de 800 Km². Destes, 511 poços estão em operação e 148 foram considerados secos ou desativados. Os resultados revelaram a existência de 98 poços na zona urbana e 579 no meio rural, sendo 304 de uso comunitário. As análises de parâmetros fisicoquímicos realizadas em amostras de água obtidas de 32 poços comunitários destinados exclusivamente para consumo humano apontam para a existência de problemas pontuais de qualidade. No entanto, a análise microbiológica aponta dados preocupantes,...
