Abstract
Abstract: In this paper we review results of research to summarize the state-of-knowledge of the past, present, and potential future roles of tropical forests in the global C cycle. In the pre-industrial period (ca. 1850), the flux from changes in tropical land use amounted to a small C source of about 0.06 Pg yr−1. By 1990, the C source had increased to 1.7 ± 0.5 Pg yr−1. The C pools in forest vegetation and soils in 1990 was estimated to be 159 Pg and 216 Pg, respectively. No concrete evidence is available for predicting how tropical forest ecosystems are likely to respond to CO2 enrichment and/or climate change. However, C sources from continuing deforestation are likely to overwhelm any change in C fluxes unless land management efforts become more aggressive. Future changes in land use under a “business as usual” scenario could release 41–77 Pg C over the next 60 yr. Carbon fluxes from losses in tropical forests may be lessened by aggressively pursued agricultural and forestry measures. These measures could reduce the magnitude of the tropical C source by 50 Pg by the year 2050. Policies to mitigate C losses must be multiple and concurrent, including reform of forestry, land tenure, and agricultural policies, forest protection, promotion of on-farm forestry, and establishment of plantations on non-forested lands. Policies should support improved agricultural productivity, especially replacing non-traditional slash-and-burn agriculture with more sustainable and appropriate approaches.

In the pre-industrial period (ca. 1850), the flux from changes in tropical land use amounted to a small C source of about 0.06 Pg yr−1. By 1990, the C source had increased to 1.7 ± 0.5 Pg yr−1. The C pools in forest vegetation and soils in 1990 was estimated to be 159 Pg and 216 Pg, respectively. No concrete evidence is available for predicting how tropical forest ecosystems are likely to respond to CO2 enrichment and/or climate change. However, C sources from continuing deforestation are likely to overwhelm any change in C fluxes unless land management efforts become more aggressive. Future changes in land use under a “business as usual” scenario could release 41–77 Pg C over the next 60 yr. Carbon fluxes from losses in tropical forests may be lessened by aggressively pursued agricultural and forestry measures. These measures could reduce the magnitude of the tropical C source by 50 Pg by the year 2050. Policies to mitigate C losses must be multiple and concurrent, including reform of forestry, land tenure, and agricultural policies, forest protection, promotion of on-farm forestry, and establishment of plantations on non-forested lands. Policies should support improved agricultural productivity, especially replacing non-traditional slash-and-burn agriculture with more sustainable and appropriate approaches.</abstract><note>Part II Workshop Working Group Papers</note><relatedItem type="host"><titleInfo><title>Water, Air, and Soil Pollution</title><subTitle>An International Journal of Environmental Pollution</subTitle></titleInfo><titleInfo type="abbreviated"><title>Water Air Soil Pollut</title></titleInfo><genre type="journal" displayLabel="Archive Journal"></genre><originInfo><dateIssued encoding="w3cdtf">1993-10-01</dateIssued><copyrightDate encoding="w3cdtf">1993</copyrightDate></originInfo><subject><genre>Environment</genre><topic>Hydrogeology</topic><topic>Atmospheric Protection/Air Quality Control/Air Pollution</topic></subject><identifier type="ISSN">0049-6979</identifier><identifier type="eISSN">1573-2932</identifier><identifier type="JournalID">11270</identifier><identifier type="IssueArticleCount">50</identifier><identifier type="VolumeIssueCount">4</identifier><part><date>1993</date><detail type="volume"><number>70</number><caption>vol.</caption></detail><detail type="issue"><number>1-4</number><caption>no.</caption></detail><extent unit="pages"><start>71</start><end>94</end></extent></part><recordInfo><recordOrigin>Kluwer Academic Publishers, 1993</recordOrigin></recordInfo></relatedItem><identifier type="istex">290C88253F0C51B4253E825F08D80CCAEAB4E47F</identifier><identifier type="DOI">10.1007/BF01104989</identifier><identifier type="ArticleID">BF01104989</identifier><identifier type="ArticleID">Art8</identifier><accessCondition type="use and reproduction" contentType="copyright">Kluwer Academic Publishers, 1993</accessCondition><recordInfo><recordContentSource>SPRINGER</recordContentSource><recordOrigin>Kluwer Academic Publishers, 1993</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
