Water is a natural resource of significant economic, social, environmental and in many cases also cultural. Regions are suffering water shortages, both in quantity and quality. The Amazon, ironically known as a reserve of water resources, is also hostage to the lack of access to clean drinking water. The water supply in the islands of Belém is poor and propose alternatives that will ensure access to decent water quality is a major challenge. In this sense, the objective of this study is to evaluate the feasibility of the use of rainwater for potable supply in the islands and Grande and Murutucu as a way of promoting local sustainable development. For this, we carried out to characterize socioeconomic survey of the forms of water applied in the area, as well as analysis of the perception of the riverine and the use of rainwater, according to aspects of acceptability and interest in acquiring. It was found that 43% of riparian needs are remedied by buying potable water coming from wells (not proven), which spends about 11% of family income, spending more than the residents of Belém with water. Still on supplies nearly 20% consume water from the river. The investigation revealed that the Grande Island about 45% of the population being treated through the water, another area in this figure is 30%. It was found that 61.4% of residents of Grande Island are in favor of consumption of rainwater, since the island Murutucu portion corresponds to 50.4%. The aspect that inhibits the use of rain water is the taste. Although environmentally and socially viable, the proposed system proved financially unfeasible since most of the population earn less than a minimum wage, thus the system is partly possible.

Avaliação de substratos orgânicos no cultivo de orquídeas nativas da APA ilha do Combu, Belém, Pará, Brasil

The natural fibers are being considered in the cultivation of orchids, including the coconut fiber as the most promising. However, other natural organic waste can be used in the cultivation. The study was conducted in the Area of Environmental Protection Island Combu located in Belém. The objective was to evaluate the effects of organic substrates in orchids cultivation, where were selected Brassia chloroleuca Barb.Rod. and Sobralia macrophylla Rchb f. native of APA and subjected to four substrates considered as treatments (T1 - fiber from the stem of açai palm; T2 - the coconut fiber, T3 - seeds of açai palm and T4 - sawdust). The experimental design was completely randomized with 4 treatments and 4 replicates (10 individuals/replicate). The parameters were evaluated: the diameter, length, number of shoots, leaf number and rate of survival for pseudobulbos of Brassia chloroleuca and shoots of Sobralia macrophylla. Data were inserting into the spreadsheet program Bioestat 5.0. and subjected to analysis of variance and averages compared by the Tuckey test at 5% to assess the degree of significance of the effects of treatments. The results showed that the fiber from the stem açaí palm promoved development of vegetative structures followed by sawing in pseudobulbos of B. chloroleuca and S. macrophylla fiber to the stem and seeds of the açaí palm promoved greater growth. It was concluded that the fiber of the stalk of açai palm can be used in the cultivation of species with ecological and sustainable recovery after cutting the açaí palm.
