ANALYSE THE VULNERABILITY IN THE MARANHÃO ILHA, BRAZIL, USING GIS TECHNIQUES AND GEOSPATIAL INFERENCE

Vulnerability and sustainability studies of an area help to assess both its level of exposure and capacity to support possible environmental impacts, and it is of primordial importance for proposals of the Legislation on Zoning, Allotment, Land Use/land cover, aiming to stimulate those areas indicated for urban growth, to discourage growth of overcrowded areas, to detect sections with restrictive use, as well as districts for permanent protection. This paper aims to analyze the vulnerability in the Maranhão Ilha, using GIS techniques, geospatial inference intersected with relevant social-environmental indicators.Estudos de vulnerabilidade e de sustentabilidade de uma área ajudam a avaliar o seu grau de exposição e sua capacidade de suporte a possíveis impactos ambientais, sendo fundamental para propostas de Lei de Zoneamento, Parcelamento, Uso e Ocupação do Solo, tendo por finalidade orientar as áreas onde deverá haver estímulo para o crescimento urbano; contenção da malha urbana; detecção de locais com possibilidade de uso restritivo, bem como locais de proteção permanente. Este trabalho propõe analisar o índice de vulnerabilidade a perda de solo da Ilha do Maranhão com base na metodologia proposta por (CREPANI, et al. 2001) e em técnicas de inferência espacial com apoio na AHP (Análise Hierárquica de Processo).

Participación comunitaria y legislación en El Salvador. Análisis de la legislación identificada

Community participation has been considered strategic in order to achieve effectiveness in political, economical, social, educational and cultural change processes as a mean of guarantying effectiveness, quality and sustainability in social policy. Accordingly, this participation must be stimulated and promoted through national legislation since it has traditionally and historically been imposed and undemocratic. Education, as an essentially human act, is a first order instrument that societies must take advantage of in order to develop and stimulate democratic participation. Therefore, education may represent a new culture: one of democratic participation as a fundamental way to empower and develop a Peace culture.

Consideraciones básicas del pensamiento complejo de Edgar Morin, en la educación

This essay consists of a brief description and analysis of Edgar Morin´s complex thinking. For that reason, it focuses on the systematic approach that refers to the interconnection and interactions of objects, people, and environment as a whole, which serve as the basis of the educational proposal, where knowledge must be regarded as an integrated fashion and not as something fragmented. Thus, human knowledge should raise awareness that we are just a component of a more general system (complex and in constant interaction), where education can be an effective source for students to develop the capacity of understanding other complex systems, besides living organisms, where also there is a big influence from “new sciences” and humanities. Therefore, the purpose of this work is to develop those ideas proposed by Edgar Morin.

La importancia de la educación ambiental ante la problemática actual

The dominant development system with its neoliberal policies and market-centered approaches contribute to aggravate the socio-environmental problems, under the context of the globalization of the market. For that reason, the concern about the sustainable development of the environment makes highly necessary the structuring of an environmental education that forms and informs about this problem. As a result, environmental education constitutes the educational process that deals with the relation between the human being and his/her environment (natural and man-made) and with itself, as well as the effects caused by this relation. In this way, environmental education must constitute an integral process, which plays its role throughout the whole teaching and learning intertwinement. For this reason it is necessary to establish an educational process that examines the relation of any topic or human being activity, within an analysis of the importance or incidence on social life, as it is the pedagogical part and its political essence.
