Zoning the physical environment as a subsidy to the management and spatial planning in amazonian conservation units and surroundings - the case of the jamari national forest

The current rates of population growth impose on society the increasingly rationaliseduse of spaces. In this sense, the use of zoning can help the understanding of socio-economic and environmental dynamics that would orient the use and occupation of spaces, identifying relationships and impacts on capacity and agricultural aptitude, as well as subsidisingthe implementation of spatial planning policies. The objective of this work was to develop a zoning proposal aimed at making the productive and conservationist aspects from the physical environment properties compatible to the Amazon conservation units and surroundings using as a case study the area of the Jamari National Forest. Environmental zones were compartmentalisedby crossing geological and geomorphological information that resulted in factors and properties that allowed the identification of homologous units in the landscape.The methods used to delimit the environmental zones were interpretation, processing and analysis of images validated in the fieldwork, determination of granulometric and mineralogical values, and petrographic analyses. The results showed, in the proposed scale, the existence of five homologous environmental zones represented on a map under the names ofJacundá, Itapuã, Nascente, LateritaandCujubim zones. The method proved to be effective in evidencing environmental differences in relatively large areas, such as the Amazon conservation areas, making it possible to identify characteristics of the physical environment that allow the orientation between society and nature in order to maintain and improve the conditions of use of natural resources in rural properties located around the Amazon conservation units.
