description As agreed under United Nations Framework Convention on Climate Change, activities reducing emissions from deforestation, forest degradation, sustainable management of forests, enhancement and conservation of forest carbon stocks (REDD+) provide financial incentives to countries mitigating climate change. Countries are requested to develop so-called national forest reference levels (FRLs) as a benchmark to measure performance of land-use policy adjustments. FRLs are constructed combining information on the magnitude of anthropogenic interventions causing greenhouse gas (GHG) emissions (e.g. historic deforestation) with information capturing the changes in different forest carbon pools. Small-island countries face the particular challenge that their FRLs have to be developed in a sparse data environment. Poor satellite coverage in the past hampers the reconstruction of deforestation patterns. This thesis combines existing national deforestation data with global deforestation data and SAR-based deforestation detection to reconstruct evolving deforestation patterns across a twenty years period (1990-2010) in Espiritu Santo Island, Vanuatu, a country located in the South Pacific. The deforestation pattern is used as an input to Dinamica EGO, a spatial modeling environment projecting future trajectories based on spatial proxies capturing driver and underlying causes of deforestation. To estimate corresponding GHG emissions, an aboveground biomass map was derived from ALOS Palsar SAR data. Overall, a total of 3,296,823 tCO2e will be released under the business-as-usual scenario (BAU) over a period of 10 years (2011-2020). Uncertainties remain high due to the heterogeneity of optical and SAR data as well as suitable historical VHR data for verification purposes.

Los países deben desarrollar llamados niveles de referencia forestales (NRFs) como referencias para medir el desempeño de políticas del uso de la tierra ajustadas. Los NRF se construyen combinado información sobre la magnitud de intervenciones antropógenas causando emisiones de gases de efecto invernadero (GEI) p. ej. a través de la deforestación con información que capta los cambios en los diferentes reservorios forestales de carbono. Los países constituidos por pequeñas islas enfrentan el desafío particular, que tienen que desarrollar sus NRFs bajo la restricción de una escasez de datos. La baja cobertura de sus territorios, perjudica la reconstrucción de patrones históricos de la deforestación por sensores remotos en el pasado. Esta tesis, desarrollada para la Isla Espiritu Santo, Vanuatu, un país en el Pacífico del Sur; combina datos nacionales existentes de la deforestación histórica con datos globales de la deforestación y patrones de deforestación generados por un procesamiento de radar de apertura sintética (SAR) para reconstruir el patrón de la deforestación emergiendo durante un periodo de 20 años (1990-2010) en la isla. Se utiliza el patrón reconstruido como un insumo de DinamicaEGO, una caja de herramientas de modelaje espacial para proyectar futuras trayectorias a base de proxies espaciales que capten los factores principales y causas subyacentes de la deforestación. Para estimar las emisiones de GEI correspondientes, se procesaron datos de SAR del sensor ALOS Palsar para derivar un mapa de biomasa aérea. En total, 3,296,823 tCO2 serían emitidas bajo un escenario “todo permanece igual” (BAU) cubriendo un periodo de 10 años (2011-2020). Las incertidumbres permanecen altas por la heterogeneidad de los datos ópticos y SAR y por la falta de datos históricos de resolución muy alta para la verificación.104 h. : il.enQuito, 2015.http://creativecommons.org/licenses/by-nc-sa/3.0/ec/info:eu-repo/semantics/openAccessCentros culturales - Diseño y construcción - Otavalo (Ecuador)Centros culturales - ArquitecturaArquitecturaBellas artesProjecting deforestation trends on Espiritu Santo island, Vanuatu, using a spatial modeling approach : a case study to develop a spatially explicit forest reference emission level for REDD+info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisreponame:Repositorio Universidad San Francisco de Quitoinstname:Universidad San Francisco de Quitoinstacron:USFQMéndez Zeballos, DorysTHUMBNAIL113628.pdf.jpg113628.pdf.jpgGenerated Thumbnailimage/jpeg979http://repositorio.usfq.edu.ec/bitstream/23000/4093/4/113628.pdf.jpgbc177e95802689fad4ac7de54e0c6e27MD54open accessORIGINAL113628.pdf113628.pdfTESIS A TEXTO COMPLETOapplication/pdf8685713http://repositorio.usfq.edu.ec/bitstream/23000/4093/1/113628.pdf3786b44bafeae1e78901f8a13c67d427MD51open accessLICENSElicense.txtlicense.txttext/plain; charset=utf-81748http://repositorio.usfq.edu.ec/bitstream/23000/4093/2/license.txt8a4605be74aa9ea9d79846c1fba20a33MD52open accessTEXT113628.pdf.txt113628.pdf.txtExtracted texttext/plain40163http://repositorio.usfq.edu.ec/bitstream/23000/4093/3/113628.pdf.txt3ea3e3f066a538cda68ba5687b63526eMD53open access23000/40932024-03-12 12:41:57.993open accessoai:repositorio.usfq.edu.ec:23000/4093Tk9URTogUExBQ0UgWU9VUiBPV04gTElDRU5TRSBIRVJFClRoaXMgc2FtcGxlIGxpY2Vuc2UgaXMgcHJvdmlkZWQgZm9yIGluZm9ybWF0aW9uYWwgcHVycG9zZXMgb25seS4KCk5PTi1FWENMVVNJVkUgRElTVFJJQlVUSU9OIExJQ0VOU0UKCkJ5IHNpZ25pbmcgYW5kIHN1Ym1pdHRpbmcgdGhpcyBsaWNlbnNlLCB5b3UgKHRoZSBhdXRob3Iocykgb3IgY29weXJpZ2h0Cm93bmVyKSBncmFudHMgdG8gRFNwYWNlIFVuaXZlcnNpdHkgKERTVSkgdGhlIG5vbi1leGNsdXNpdmUgcmlnaHQgdG8gcmVwcm9kdWNlLAp0cmFuc2xhdGUgKGFzIGRlZmluZWQgYmVsb3cpLCBhbmQvb3IgZGlzdHJpYnV0ZSB5b3VyIHN1Ym1pc3Npb24gKGluY2x1ZGluZwp0aGUgYWJzdHJhY3QpIHdvcmxkd2lkZSBpbiBwcmludCBhbmQgZWxlY3Ryb25pYyBmb3JtYXQgYW5kIGluIGFueSBtZWRpdW0sCmluY2x1ZGluZyBidXQgbm90IGxpbWl0ZWQgdG8gYXVkaW8gb3IgdmlkZW8uCgpZb3UgYWdyZWUgdGhhdCBEU1UgbWF5LCB3aXRob3V0IGNoYW5naW5nIHRoZSBjb250ZW50LCB0cmFuc2xhdGUgdGhlCnN1Ym1pc3Npb24gdG8gYW55IG1lZGl1bSBvciBmb3JtYXQgZm9yIHRoZSBwdXJwb3NlIG9mIHByZXNlcnZhdGlvbi4KCllvdSBhbHNvIGFncmVlIHRoYXQgRFNVIG1heSBrZWVwIG1vcmUgdGhhbiBvbmUgY29weSBvZiB0aGlzIHN1Ym1pc3Npb24gZm9yCnB1cnBvc2VzIG9mIHNlY3VyaXR5LCBiYWNrLXVwIGFuZCBwcmVzZXJ2YXRpb24uCgpZb3UgcmVwcmVzZW50IHRoYXQgdGhlIHN1Ym1pc3Npb24gaXMgeW91ciBvcmlnaW5hbCB3b3JrLCBhbmQgdGhhdCB5b3UgaGF2ZQp0aGUgcmlnaHQgdG8gZ3JhbnQgdGhlIHJpZ2h0cyBjb250YWluZWQgaW4gdGhpcyBsaWNlbnNlLiBZb3UgYWxzbyByZXByZXNlbnQKdGhhdCB5b3VyIHN1Ym1pc3Npb24gZG9lcyBub3QsIHRvIHRoZSBiZXN0IG9mIHlvdXIga25vd2xlZGdlLCBpbmZyaW5nZSB1cG9uCmFueW9uZSdzIGNvcHlyaWdodC4KCklmIHRoZSBzdWJtaXNzaW9uIGNvbnRhaW5zIG1hdGVyaWFsIGZvciB3aGljaCB5b3UgZG8gbm90IGhvbGQgY29weXJpZ2h0LAp5b3UgcmVwcmVzZW50IHRoYXQgeW91IGhhdmUgb2J0YWluZWQgdGhlIHVucmVzdHJpY3RlZCBwZXJtaXNzaW9uIG9mIHRoZQpjb3B5cmlnaHQgb3duZXIgdG8gZ3JhbnQgRFNVIHRoZSByaWdodHMgcmVxdWlyZWQgYnkgdGhpcyBsaWNlbnNlLCBhbmQgdGhhdApzdWNoIHRoaXJkLXBhcnR5IG93bmVkIG1hdGVyaWFsIGlzIGNsZWFybHkgaWRlbnRpZmllZCBhbmQgYWNrbm93bGVkZ2VkCndpdGhpbiB0aGUgdGV4dCBvciBjb250ZW50IG9mIHRoZSBzdWJtaXNzaW9uLgoKSUYgVEhFIFNVQk1JU1NJT04gSVMgQkFTRUQgVVBPTiBXT1JLIFRIQVQgSEFTIEJFRU4gU1BPTlNPUkVEIE9SIFNVUFBPUlRFRApCWSBBTiBBR0VOQ1kgT1IgT1JHQU5JWkFUSU9OIE9USEVSIFRIQU4gRFNVLCBZT1UgUkVQUkVTRU5UIFRIQVQgWU9VIEhBVkUKRlVMRklMTEVEIEFOWSBSSUdIVCBPRiBSRVZJRVcgT1IgT1RIRVIgT0JMSUdBVElPTlMgUkVRVUlSRUQgQlkgU1VDSApDT05UUkFDVCBPUiBBR1JFRU1FTlQuCgpEU1Ugd2lsbCBjbGVhcmx5IGlkZW50aWZ5IHlvdXIgbmFtZShzKSBhcyB0aGUgYXV0aG9yKHMpIG9yIG93bmVyKHMpIG9mIHRoZQpzdWJtaXNzaW9uLCBhbmQgd2lsbCBub3QgbWFrZSBhbnkgYWx0ZXJhdGlvbiwgb3RoZXIgdGhhbiBhcyBhbGxvd2VkIGJ5IHRoaXMKbGljZW5zZSwgdG8geW91ciBzdWJtaXNzaW9uLgo=Institucionalhttp://repositorio.usfq.edu.ecInstitución privadausfqhttp://repositorio.usfq.edu.ec/oaiEcuador...opendoar:22902024-03-12T17:41:57falseInstitucionalhttp://repositorio.usfq.edu.ecInstitución privadausfqhttp://repositorio.usfq.edu.ec/oai.Ecuador...opendoar:22902024-03-12T17:41:57Repositorio Universidad San Francisco de Quito - Universidad San Francisco de Quitofalse
