Item Maquete temática: deterioração dos recursos hídricos(2019-02-14) Moraes, Guilherme Souza de; Dill, Paulo Roberto Jaques; http://lattes.cnpq.br/4253323933047125; http://lattes.cnpq.br/0640280937337680The lack of basic sanitation is one of the worst infrastructural problems in Brazil. Practically half of the population does not have access to basic sanitation of any type. Every person may feel impaired, but some figures show inequalities: children are the most affected in terms of mortality; the regions North and Northeast have the worst coverage index; rural population is the most neglected. Rivers, shores and streets are frequent destinations of the waste water. The majority of sewage systems pollutes the environment, however this pollution is not easily observable since sewage goes subterraneous, to groundwater. Groundwater supplies rivers and reservoirs. Then, water quality of a spring can influence water quality of reservoirs. At the same time, there are solutions that can be implemented in rural areas to the treatment of sewage. One of the solutions is the model denominated “Tratamento de Efluentes Caseiros” (literally translated as “Homemade Effluent Treatment”), developed by Rocha (2001), which is a type of ecological sanitation. In this system, human dejects are fermented and mineralized, and plants absorb minerals and water. However, for implementing this technology, rural population needs to know it and understand its importance, what Environmental Education, or Rural Extension can help. The present work objected developing a thematic scale model that could help students to understand that technology operation, comparing it with a rudimentary sewage system (pit latrine). A thematic scale model reproduced those two designs, and obtained high perception from students about the final difference of water quality. Therefore, the thematic model scale can be utilized in classes of Environmental Education to approach contamination of water resources through sanitary sewage system.Item Situação dos recursos hídricos e da irrigação nos Municípios do Agreste Meridional de Pernambuco, a partir do censo agropecuário de 2017(2019-02-08) Carvalho, Felipe Galindo Jácome de; Borges Filho, Epaminondas Luiz; http://lattes.cnpq.br/9634125258121902; http://lattes.cnpq.br/4435208873918259Currently Brazil has an irrigated area of 6.95 million hectares. The knowledge of the irrigated areas and their geographic distribution is of fundamental importance for the planning of the management of the water resources. The objective of this work was to analyze the situation of water resources and irrigated agriculture in the municipalities that make up the Meridonal Agreste of Pernambuco from the Agricultural Census of 2017. The methodology of the work was divided into four stages: i) characterization of irrigation and its evolution in Brazil and in the world; ii) socioeconomic survey and surface and groundwater resources of the municipalities of the Meridional Agreste; iii) survey of the water resources present in agricultural establishments and iv) the characterization of the irrigation used in the municipalities of the agreste region according to the irrigation method employed. The Meridional Agreste region is mainly cut by intermittent rivers and the groundwater potential for irrigation utilization is low, due to the high concentration of salts present in the water in much of the region. The municipalities of Brejão, Tupanatinga, Garanhuns, Saloá, Buíque, Canhotinho and Paranatama presented more than 50% of the groundwater sweet. The municipalities of Iati, Capoeiras, Venturosa, Águas Belas, Itaíba, Caetés, Pedra, Bom Conselho, Jurema, Lagoa do Ouro and Lajedo were the municipalities that presented more than 50% of the saline groundwater. Of the Meridional Agreste establishments, 86.8% do not have springs and 75.4% do not have rivers / streams. Of these resources, only 29.8% of the springs and 32.2% of the rivers / streams are protected by forests. 65.1% of the establishments declare to have cisterns, 26.0% declare to have a well and 22.2% declare that they do not have a cistern or a well. Irrigation is present in only 6.8% of Meridional Agreste establishments and the most used methods were localized Irrigation (34.3%), wetness (33.1%) and sprinkler (25.1%).
