O presente trabalho aborda os problemas relacionados com a escassez de água, os desafios para preservação, as perspectivas futuras e a conscientização da população. Mostra que grande parcela da população mundial já sofre com a falta de água potável, levando a conflitos pelos usos múltiplos da água. As diversas formas de poluição causam degradação dos rios, lagos e aquíferos prejudicando todas as formas de vida, desequilibrando todo o ecossistema. Novas tecnologias para agricultura, estratégias para aumentar as reservas de água potável tanto superficiais quanto subterrâneas e estratégias para o reaproveitamento de água são medidas encontradas para um consumo sustentável

A large proportion of fresh water is greatly impaired due to increasing pollution; this could be minimized through the expansion of investment in sanitation programs. But the major problem faced by third world countries and developing ones in this respect, is the high cost of projects and their implementation. In an attempt to find a simple technology, efficient and inexpensive, this study aimed to verify the effectiveness of using constructed wetland systems (CWS) for removal of bacteria and nutrients from sanitary sewer effluent from the STS Piracicamirim - Piracicaba - SP. The installation of prototypes was followed, and testing prior to regularize the flow held, but due to malfunction of these and outages of the STS activity can not evaluate the effectiveness of both as to the parameters proposed: temperature, pH, dissolved oxygen, conductivity, total dissolved solids (TDS), nitrite, nitrate, ammonia, total nitrogen, total phosphorus, chemical oxygen demand (COD), sulfide, sulfate, biochemical oxygen demand (BOD), total coliform and Escherichia coli. To establish results about the effectiveness of these types if the system were conducted literature reviews of papers published with the same theme. Analysis of these results showed fairly good efficiencies in wastewater treatment, especially for nutrients and coliforms

This paper is about a case study of using solar energy and wind energy in a farm. For this purpose were collected from the property, such as water consumption and amount of residents. So, we estimate how many conventional panels or PET bottle panels and boiler needed to supply the farm with warm water. It also calculates the amount of photovoltaic panels and the main accessories for converting solar energy into electrical energy. For the pumping of water using photovoltaic panels is dismissed and dimensioned to be a watermill

The aim of this experiment was to study the influence of transparent, blue and red tree shelters on gas exchanges of canafístula’s (Peltophorum dubium (Spreng.) Taub.) seedlings. This study was carried out in Department of Botany, Institute of Biosciences, U ESP, Botucatu, São Paulo State, Brazil. The experiment design was randomized blocks, with 5 replications, each one containing 6 units of each treatment (nonsheltered, transparent tree shelters, blue tree shelters and red tree shelters). The evaluations of gas exchanges were made through an infrared gas analyzer. It follows that the tree shelters use may limit the photosynthesis, increase the transpiration and stomatal opening, besides reducing the water use efficiency. The colored tree shelters use created unfavorable conditions for the development, reducing the photosynthesis, because they reflected the blue and red wavelengths, allowing only the passage of the other components of the white light or of the photosynthetically active radiation
