Geo-environmental zoning using physiographic compartmentalization: a proposal for supporting sustainable decision-making

Abstract

The geo-environmental zoning represents an important strategy in the territorial management. However, it requires a logical and structured procedure. Therefore, an approach using physiographic compartmentalization is proposed and applied as case study in a region covered by the topographic maps of São José dos Campos and Jacareí, Brazil. This region has great geological and geomorphological peculiarities, beyond being a place with large human interventions because of its quickly economic growth. The methodology is based on photointerpretation techniques and remote sensing in GIS environment. As a result, seven geo-environmental zones were obtained from a weighted integration by multicriteria analysis of physiographic units with land-use classes. In conclusion, taking into account potentialities and limitations, the proposed approach can be considered able to support sustainable decision-making, being applicable in other regions.

Methods of Geoecological Zoning Using Geotechnical Cartographic Base (through the Example of Karaganda Region of Kazakhstan)

“…At present, there is no single methodological approach to geoecological zoning of the territory, but there are many viewpoints on the problem [5]. It exhibits two trends: landscape-geomorphological [6][7][8], and indicator-ecological [9]. Geoecological zoning of the territory is the result of different manifestations of natural and anthropogenic processes and phenomena, or zoning factors, such as geological structure, history of geological development, landscape-climatic conditions, manifestations of endogenous and exogenous, and geological hazards [10,11] , and an anthropogenic impact [4,7].…”

As a result of geoecological zoning, maps of geoecological conditions can be compiled, including those used to solve specific problems, the risks of economic development and economic assessment of the consequences of anthropogenic impact, territory pollution, resistance to anthropogenic impact and other special maps, and primarily digital GIS based maps [12,13].…”

Aplicabilidade do ponto de entrega voluntária como coleta seletiva

“…Regarding to physical factors, the physiographic compartmentalization allows the zoning of a given region in areas with homogenous physical characteristics, contributing for territorial planning and management (Corrêa et al, 2017). Thus, physiographic compartmentalization could provide an approach able to support susceptibility mapping.…”

Avaliação da suscetibilidade a escorregamento na Serra do Mar pela aplicação da compartimentação fisiográfica

“…A compartimentação fisiográfica é um método que utiliza ferramentas de sensoriamento remoto, como a fotoanálise e a fotointerpretação, para o estudo do comportamento do meio (Vedovello e Mattos, 1998;Zaine, 2000Zaine, , 2011Amaral et al, 2015;Chaves et al, 2015;Corrêa et al, 2017). Esse método baseia-se na análise dos elementos componentes do meio físico, em relação a sua natureza geomorfológica e geológica, e na identificação da ocorrência de processos de dinâmica superficial (Vedovello e Mattos, 1998;Oliveira, 2004;Zaine, 2000Zaine, , 2011Rodrigues, 2012;Amaral et al, 2015;Chaves et al, 2015;Corrêa et al, 2017).…”
