The challenge confronted by farmers during prolonged periods of soil water stress is to guarantee the restoration of water and maintain the productivity of agricultural crops. Even in regions such as Amazon, the variability in the precipitation regime should be considered in agricultural planning. There are regions in which 80% of annual rainfall is concentrated between December and June. It is exactly during this period of low rainfall that small-scale family-based farmers need technological assistance to guarantee that their crops remain irrigated in order to maintain their income in this rural environment. The IrrigaPot arises as an alternative that is able to access rainfall that has been stored since the rainy season and provide it to plants when the soil is dry. The pots are maintained full with 20 liters of water, and through capillary action the soil maintains them constantly humid. This technology does not require specific knowledge with respect to irrigation regimes and is necessary for the farmer to dedicate his time to replacing water. The technology is totally automated through a simple system using a float, tubes, and connectors that connect a rubber hose to the lids of the pots buried in the soil.

A pesquisa teve como objetivo analisar as transformações no trato da relação entre a produção dos resíduos sólidos (especificamente pilhas e baterias), para viabilizar a implantação de Ponto de Coleta Voluntária na universidade do estado do Pará Campus VI. Os dados obtidos em relação a necessidade de existência da implantação de um coletor seletivo para pilhas e baterias no Campus VI - Paragominas, indicaram que, a maioria dos indivíduos amostrados (95,6%) perceberam tal necessidade. Com isso, foi comprovada a viabilidade de implantação desse tipo de coletor seletivo e que o Campus VI pode ser um Ponto de Entrega Voluntário para pilhas e baterias para determinar uma mitigação quanto a disposição final desses geradores de energia.

The Amazon region maintains the largest drainage network in the world. In addition, the hydrographic basin of this region has a potential for hydroelectric power generation greater than the current Brazilian production level, which generates about 78,000 MW. The objective of this research was the accomplishment of a qualitative analysis between the relation of the Brazilian energy policy, associated with the development model adopted for the Amazon region, the conflicts that this originates. The data obtained and analyzed indicated that in the year 2016, the CPT registered 14 conflicts associated with water resources in the region, of which 57.9% involve hydroelectric dams. Thus, the relationship of the current energy model applied to the Amazon is imbalanced, resulting in conflicts with the communities where UHE's are built.
