Compost and vermicompost, produced from organic fraction of municipal solid wastes were studied as components of potting media for Licania tomentosa (oiti) seedlings production. The objective was to achieve data to amplify the utilization of these products, in order to utilize them to ornamental and urban arborization species. Increasing rates of organic fertilizers were used until the total soil substitution from the potting media. There were no fitotoxic effects. Compost or vermicompost caused higher germination index of seeds and higher growth of plants. The study demonstrated that it is possible to utilize these products in other activities beyond aplication in agricultural soil, and it can generate new markets to this kind of organic fertilizer.

The environmental analysis is an important tool used in forecasting and mitigation of environmental problems. Focusing on the occupation of marginal areas of the Corumbataí River in an urban stretch in the city of Rio Claro (SP), this study aimed to gather information on situations of risk, both to the environment and the population, verified in that area. Through field observation and in specific studies, the geological and geotechnical aspects, the characteristics of surface waters and aspects of urbanization were analyzed. The results show that the environmental problems diagnosed are related to lack of planning in the occupation of the area. Moreover, the natural characteristics of the physical environment expose people to risks such as floods and soil slides.
