Abstract
Abstract: Landsat TM scenes for 1985 and 1991 are used to produce a georeferenced map of land cover and land use for an area of the Amazon estuary inhabited by three populations of caboclos with distinct patterns of land use. This information is combined in a geographic information system with ethnographic and survey research carried out over the past 5 years to develop representative spectral “signatures” which permit measurement and differentiation of land uses and the detection of change even between small areas of managed floodplain forest and unmanaged forest, and between three distinct age/growth classes of secondary succession following deforestation. Implementation of these procedures permit the scaling up or down of research at different resolutions. Three distinct patterns of land use are examined with differential impact on the environment. Mechanized agriculture at one site has eliminated virtually all the mature upland forest and is now dominated by secondary successional vegetation. The more traditional system of diversified land use at the next site shows a subtle cycling of flooded forest to managed palm forest through time in response to the price of palm fruit and cycling in the use of fallow land. A third site, based on palm fruit extractivism, shows minimal changes in land cover due to persistent specialization on management of flooded forest extraction. There is little evidence that the community with the greatest impact on forest cover is any better off economically than the two communities which have minimal impact on the landscape. This study suggests how a balance between use and conservation in Amazonia may be achieved in floodplain and estuarine areas, and the effectiveness of monitoring these types of land cover from satellite platforms.

A third site, based on palm fruit extractivism, shows minimal changes in land cover due to persistent specialization on management of flooded forest extraction. There is little evidence that the community with the greatest impact on forest cover is any better off economically than the two communities which have minimal impact on the landscape. This study suggests how a balance between use and conservation in Amazonia may be achieved in floodplain and estuarine areas, and the effectiveness of monitoring these types of land cover from satellite platforms.</abstract><relatedItem type="host"><titleInfo><title>Human Ecology</title><subTitle>An Interdisciplinary Journal</subTitle></titleInfo><titleInfo type="abbreviated"><title>Hum Ecol</title></titleInfo><genre type="journal" displayLabel="Archive Journal"></genre><originInfo><dateIssued encoding="w3cdtf">1994-09-01</dateIssued><copyrightDate encoding="w3cdtf">1994</copyrightDate></originInfo><subject><genre>Social Sciences, general</genre><topic>Environmental Management</topic><topic>Anthropology/Archaeometry</topic><topic>Sociology</topic></subject><identifier type="ISSN">0300-7839</identifier><identifier type="eISSN">1572-9915</identifier><identifier type="JournalID">10745</identifier><identifier type="IssueArticleCount">8</identifier><identifier type="VolumeIssueCount">4</identifier><part><date>1994</date><detail type="volume"><number>22</number><caption>vol.</caption></detail><detail type="issue"><number>3</number><caption>no.</caption></detail><extent unit="pages"><start>249</start><end>278</end></extent></part><recordInfo><recordOrigin>Plenum Publishing Corporation, 1994</recordOrigin></recordInfo></relatedItem><identifier type="istex">F117166C65BF98B924C358876E52AB50C700E2E9</identifier><identifier type="DOI">10.1007/BF02168853</identifier><identifier type="ArticleID">BF02168853</identifier><identifier type="ArticleID">Art2</identifier><accessCondition type="use and reproduction" contentType="copyright">Plenum Publishing Corporation, 1994</accessCondition><recordInfo><recordContentSource>SPRINGER</recordContentSource><recordOrigin>Plenum Publishing Corporation, 1994</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
