A inserção da educação ambiental não formal no processo de implantação de saneamento ambiental na comunidade rural Colonia Mergulhão, São José dos Pinhais - PR

One of the biggest environmental problems of the population is the lack of sewage treatment, especially in rural communities and low-income. The development of technologies for efficient, low-cost sanitation need to be developed to meet the disadvantaged people of this basic service. This work was the implementation proposal of a technology called constructed wetlands, also known as Wastewater Treatment Plant for Roots Zone - ETEZR. The objective was to develop a non- formal environmental education proposal for redevelopment, using outreach methods for residents and deployment of this technology ETEZR in the rural community of Cologne Grebe in Sao Jose dos Pinhais - PR. With technical support from the Paranaense Technical Assistance and Rural Extension Institute -EMATER and the Federal Technological University of Paraná - UTFPR, 5 ETEZR were deployed in the colony through three theoretical and practical workshops, which involved total 67 people from the community 5 technicians EMATER and 13 of the Municipal Town Hall. Após4 months of implementation were carried out two collections of raw wastewater and treated to analyze physical, chemical and biological parameters. The results evaluated by chemical parameters BOD, COD, phosphorus, ammonia nitrogen comparing raw and treated sewage, demonstrate that ETEZR are effective in the treatment of sewage. 5 Seasons minimum and maximum efficiency between the basic parameters analyzed were 52.2 to 95.5% for BOD; 47 to 94.5% for COD; 21.5 to 96% phosphorus; 30-98% for ammonia nitrogen. Oils and greases, and a series of solid also achieved a significant reduction in their values when comparing the raw sewage and treated sewage, and biological parameters evaluated by means of coliforms showed a reduction of 80 to 99%. With the implementation of environmental education process aimed sanitation was possible to evaluate the perception of the population to accept the environmental sanitation technology using the ETEZR, understand the needs and sanitation concepts for the community. This research evaluated the development of the methodology applied by the non-formal environmental education in order to provide subsidies for rural sanitation plan process for the municipality.

Cultivo artesanal do cogumelo Shiitake: uma potencial atividade para agroecossistemas sustentáveis

Edible mushroom cultivation has been gaining ground in the agricultural environment throughout the country, creating a new product option in the food market. This activity is linked to cultural and artisanal management with environmentally sustainable principles and generates income for small farms. In this context, the present study evaluated the potential for artisanal cultivation of Shiitake as an activity for sustainable agroecosystems. Initially, the historic of implementation and evolution of artisanal cultivation of Shiitake mushroom on properties considered models in Pato Branco, Guarapuava and São José dos Pinhais (Paraná) and Frei Rogerio, (Santa Catarina) were carried out. Consequently, a comparative analysis between the cultivation systems of these properties and the use of small wooded areas and reforested areas was conducted. Aspects of production, income and pluralism of the farms, were also performed. At the end, the nutritional quality parameters of mushrooms produced in different properties were evaluated. The results show economic potential in Shiitake production. The activity also has potential for the sustainable exploitation of native forest and reforested areas, contributing to the optimal use of physical space small properties. In artisanal cultivation of Shiitake there is a systemic interaction verified by the use of wood from the same farm, assisting in the renewal of biomass of the agroecosystem. Finally, it was found that mushrooms produced on different substrates used in the studied properties have high nutritional quality. Shiitake samples exhibited high contents of protein, fiber, minerals and low fat content.
