Environmental fragility evaluation and guidelines for environmental zoning: a study case on Ibiuna (the Southeastern Brazilian region)

Environmental fragility models are important decision tools for policy makers as they help quantify environmental sensitivity and understand the relationship between human activities and environmental quality. The objective of this study was to evaluate three different environmental fragility models within the Brazilian rainforest region and to use the results to develop environmental zone classes. Two rural river basins located in Ibiuna, Sao Paulo state, Brazil, were studied. Input variables, including slope class, relief dissection rate, soil class, lithology, land cover, and climate data, were used to compute environmental fragility classes using three standard models. The model outputs were evaluated on their ability to accurately predict the most sensitive and least sensitive areas. The best models for each region were used to derive environmental zoning maps, including restoration priorities, best regions for agriculture, and areas with high needs for soil management. These maps will help support land use strategies for environmental restoration. This study provides insight into territorial ordering and management of environmental services with a regional perspective.

Planejamento ambiental da bacia hidrográfica do córrego Embirí – UGRHI Pontal do Paranapanema – São Paulo: inventário e diagnóstico

This study aimed to contribute to the environmental planning of the watershed Embirí stream - UGRHI Pontal Paranapanema (belonging to the Paranapanema Management unit) in the cities of Presidente Prudente and Regente Feijó, São Paulo. This basin is located in the area of the Santo Anastácio river source, responsible for supplying water to about 30% of the population of Presidente Prudente. The methodological procedures based on Leal (1995) and Rodriguez et al. (2004), and the steps include inventory and diagnosis of the basin. We conducted extensive literature review, cartographic and documentary on the subject area of research, field work, preparation of thematic maps and summary chart of physical units and environmental use and land cover, participatory mapping of environmental risks, quality analysis of water. Most of the basin of the stream of twine had a high environmental fragility and the main problems found were lack of riparian vegetation, erosion, siltation of water bodies, irregular disposal of debris and the dumping of sewage. The results were summarized in the diagnosis and can identify the most important environmental impacts, environmental and spatial weaknesses of the legislation, and thus draw up proposals for action to the area that is substantially degraded

Proposta de criação de um Parque Natural Municipal no entorno no bairro Mãe Preta em Rio Claro - SP

This study aims to identify the environmental and social elements that should underpin the creation of a Municipal Natural Park in accordance with Law 9985/2000, establishing the SISTEMA NACIONAL DE UNIDADES DE CONSERVAÇÃO ( SNUC ) . The northeast sector of the city of Rio Claro - SP , envolving, among others , the neighborhood Mãe Preta, the most significant of the site is consolidated as an area of significant environmental value for the consolidation of a conservation area . The proposed establishment of this unit has been discussed since the beginning of this year by Secretaria Municipal de Planejamento, Desenvolvimento e Meio Ambiente de Rio Claro- SP (SEPLADEMA ) and meets the Municipal Director Plan that provides for the establishment of several protected areas in the City . The study area suffers severe pressure due to peripheral urbanization and characterized environmental fragility according to numerous studies by researchers at UNESP, Rio Claro - SP and research in situ. Stand out in soils susceptible to sheet erosion area, the presence of a large proportion of gully area subject to flooding and significant breeding capitation water for public supply
