Water availability in rural areas is essential to production activities and quality of life. The aim of the current study is to evaluate the key role played by water resources in rural properties as a factor for farmers' permanence in the field in Southern Brazil. The research followed a qualitative and quantitative approach, which encompassed the application of semi-structured questionnaires to family farmers living in Marmeleiro and Fontana Freda communities, in the rural area of Jaguari County, Rio Grande do Sul State, Brazil. Based on collected data, participants have shown knowledge about aspects such as water quality and availability, as well as about the preservation of this resource. Nevertheless, it was clear that water availability is a fundamental factor for farmers to remain in the field.

Abstract The aim of this study was to evaluate the presence of anti-Toxocara antibodies in naturally infected broiler chickens (n = 189) from the state of Paraná, southern Brazil. The chickens were reared in a semi-intensive system by small family farmers (n = 7). An enzyme-linked immunosorbent assay (ELISA) was performed to detect the presence of anti- Toxocara spp. IgY after serum adsorption with Ascaridia galli antigens. An overall seroprevalence of 67.7% (128/189; 95% CI = 61.1-74.4) was observed. The frequency of positive animals by farm ranged from 29.6% to 100%. The optical density and reactivity index values observed in ELISA test indicated the possible chronicity of infection of the evaluated chickens. Associations between the presence of antibodies and the area where the chickens were reared (p = 0.382) or the population density of dogs on the farm (p = 0.785) were not observed. This study shows a high prevalence of Toxocara spp. antibodies in broiler chickens reared in semi-intensive systems and provides evidence that chickens are a good indicator of environmental contamination by larva migrans agents. Further studies are necessary to assess the risk factors associated with poultry infection and the likelihood of toxocariasis transmission to humans via the ingestion of free-range chicken meat.

A universalização do abastecimento de água no Brasil ainda é um desafio que se busca suplantar, sobretudo em relação ao atendimento a populações rurais difusas, onde os sistemas convencionais não respondem às demandas das famílias de agricultores dispersas. Nesse contexto, as nascentes de água podem contribuir como solução alternativa para o abastecimento doméstico, por se encontrarem próximas ao consumo e sob o controle do usuário Isto é evidenciado no estudo das nascentes situadas no Assentamento Serra Grande, no município de Vitória de Santo Antão, Zona da Mata de Pernambuco. Foram identificadas, cadastradas e selecionadas nascentes perenes, para caracterização da qualidade e vazão das águas, objetivando avaliá-las para usos múltiplos, com prioridade ao abastecimento doméstico. Evidenciou-se que a vazão, mesmo em períodos de estiagem, possui potencial de atender às necessidades básicas dos agricultores, para beber, preparo de alimentos, banho, lavagem de utensílios e roupas e descarga em sanitários. Quanto à qualidade para uso doméstico, em geral a água atende aos limites sanitários, embora em alguns casos a presença de Escherichia coli exija recuperação da nascente e cloração cuidadosa da água. Pelos resultados, a produção de água em nascentes situadas em solos e clima predominantes na Zona da Mata do Nordeste brasileiro, permite atender às necessidades básicas de abastecimento doméstico de agricultores familiares isolados ou em pequenas vilas rurais, sendo uma alternativa aos sistemas convencionais de abastecimento, já identificada pelo governo federal em seus recentes planos de abastecimento de populações rurais difusas. Palavras-chave: recursos hídricos; gestão ambiental; desenvolvimento rural  The Springs as Supply Source of Rural Diffuse Population  ABSTRACTThe universalization of the water supply in Brazil is still a challenge that it seeks to be supplant, especially in relation to the service to rural diffuse population, where conventional systems do not respond to the demands of farming families dispersed. In this context, the water springs may contribute as a workaround for domestic supply, because they are close to consumption and under user control. This is evidenced in the study of springs located at Settlement Serra Grande, located in the city of Vitória de Santo Antão, Zona da Mata de Pernambuco. It has been identified, registered and selected perennial springs, to characterize the quality and water flow, aiming to evaluate them for multiple uses with priority to domestic supply. It was evident that the flow even during drought periods, has potential to meet the basic needs of farmers, for drinking, preparing meals, baths, wash utensils and clothes and flushing toilets. As for the quality for home use, generally water meets health limits although in some cases the presence of Escherichia coli, requires careful recovery of the source and chlorination of water. According to the results, the production of water in springs located in soils and climate prevailing in Zona da Mata of Brazilian northeastern, it allows to meet basic needs for domestic supply from family farmers in small villages or isolated rural villages, being an alternative to conventional supply, already identified by the federal government in their recent plans for the supply of rural diffuse population.  Keywords: water resources; environmental management; rural development
