Caracterização sócioambiental do município de Caucaia (Ce) utilizando sistema de informação geográfica (SIG): subsídios para o ordenamento territorial

The municipality of Caucaia, located in the State of Ceara, has been showing a great population growth, resulting in a significant urban expansion accelerated in recent years. In this context, it has developed a Geographic Information System (GIS) with the main objective of realizing the socio-environmental and auxiliary activities related to management and land use. In designing the system, we used orthophotos at scales 1:20,000 (area of the city) and 1:2,000 (urban area of the seat), generating a proposed grouping of cartographic data mapped at the level of detail. From the GIS, one can perform analyzes and queries (spatial or tabular), allowing the visualization of geographic data and optimizing the search of information, contributing in a direct way in making the correct decision on the part of public managers. A point to note is the potential for future system upgrades, and the same dynamic.

ANÁLISE MULTITEMPORAL DO PROCESSO DE DEGRADAÇÃO DA VEGETAÇÃO DA BACIA HIDROGRÁFICA DO RIO JAIBARAS NO ESTADO DO CEARÁ

This study aimed to analyze a series of multitemporal LANDSAT 5, where they have gone through techniques of digital image processing, allowing to generate NDVI index (normalized difference vegetation), so it was possible to identify and quantify the levels of degradation of vegetation in the area of River Basin Jaiba / EC within 24 years, and specifically, the research conducted in the years 1985, 1992, 1996, 2007 and 2009. Through the use of classification techniques of digital image processing and field work were prepared thematic maps of the levels of degradation of the vegetation of river basin Jaiba / EC, the vegetation is classified into vegetation conserved, partially degraded, degraded, severely degraded and exposed soil, showing the wear and changes in levels of conservation of vegetation.

ANALYSIS OF THE MONITORING OF MUNICIPAL INDEX ALERT (IMA) IN STATE OF CEARA: ADVANCES AND CHALLENGES OF MUNICIPALITIES IN THE PERIOD 2004-2010

The present study aims at monitoring the Municipal Index Alert (IMA) in the period between the years 2004 to 2010, aiming to contribute to the progress and challenges municipalities face of adversity on preventive guidelines in the context of semi-arid climate in the State of Ceara, based on analysis and reflection report published annually by IPECE. It was found that the cities of Independencia, Madalena, Penaforte e Taua have always been in the class of high vulnerability.

URBAN EXPANSION (DIS) ORDERLY AND ITS CLASHES SOCIOENVIRONMENTAL: THE CASE OF THE CITY OF HORIZONTE, STATE OF CEARA

The municipality of Horizonte, located in the Metropolitan Region of Fortaleza – MRF spent the last 26 years by intense changes in their spatial configuration and in its environmental conditions, in order to separate two horizons, but connected, that outlined before and after the logic of industrialization. Thus, aimed to evaluate the territorial municipality of Horizonte, from new methods of integration and systematization of data and information by analyzing environmental. In order to quantify the urban sprawl in the years 1987, 1996, 2000, 2006 and 2010, multitemporal analysis was performed from TM/Landsat-5. In this perspective, a research has addressed, yet, historical factors that justify the use of space, well as aspects of its socioeconomic, population and its implications for environmental sanitation.
