Esta investigación identificó los impactos ambientales en la cadena de suministro de crisantemos mediante análisis de ciclo de vida -ACV. La unidad funcional fue un kg de tallos con calidad de exportación. El estudio evalúo los sistemas de flores de corte desde la extracción de materia prima hasta la comercialización del producto en dos mercados, Londres y Miami y analizó dos agroecosistemas, uno certificado ambientalmente y otro sin certificar. La fase de transporte a Londres generó mayores impactos frente al transporte a Miami, especialmente en la categoría de cambio climático (GWP100), con valores de 9,10E+00 y 2,51E+00 kg CO2-eq*UF-1 para Londres y Miami, respectivamente. Al considerar las fases previas al transporte, el sistema sin certificar generó mayor impacto que el certificado, específicamente por mayor aplicación de fertilizantes (certificado 1,448E-02 kg*UF-1, sin certificación 2,23E-01 kg*UF-1) y plaguicidas (certificado 1,24E-04 kg*UF-1, sin certificación 2,24E-03 kg*UF). En manejo de cultivo las categorías con mayor carga ambiental fueron eutroficación (EP) y acidificación (AP). En escenarios de mejora se observó que el transporte marítimo y la reducción del 50% en fertilizantes, disminuía los impactos ambientales en esta cadena de suministro.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Colombia is a major flower exporter of a wide variety of species, among which the chrysanthemum plays a major role due to its exporting volume and profitability on the international market. This study examines the major environmental impacts of the chrysanthemum supply chain through a life cycle assessment (LCA). One kg of stems export quality was used as the functional unit (FU). The study examines cut-flowers systems from raw material extraction to final product commercialization for two markets (London and Miami) and analyzes two agroecosystems: one certified system and one uncertified system. The transport phase to London resulted in more significant environmental impacts than the transport phase to Miami, and climate change (GWP100) category was significant in both cities, generating values of 9.10E+00 and 2.51E+00 kg CO2-eq*FU for London and Miami, respectively. Furthermore, when exclusively considering pre-export phases, the uncertified system was found to have a greater impact than the certified system with respect r to fertilizer use (certified 1,448E-02 kg*FU, uncertified 2.23E-01 kg*FU) and pesticide use (certified 1.24 E-04 kg*FU, uncertified 2.24E-03 kg*FU). With respect to the crop management, eutrophication (EP) and acidification (AP) processes imposed the greatest level of environmental impact. Strategies that would significantly reduce the environmental impact of this supply chain are considered, including the use of shipping and a 50% reduction in fertilizer use.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo Colômbia é um dos grandes exportadores de flores, com una importante variedade de espécies, entre as quais o Cri-sântemo (Dendranthemagrandiflora) ocupa um lugar destacado por seu volume de exportação e qualidade, nos mercados internacionais. Esta investigação identificou os impactos ambientais na cadeia de suprimento de Crisântemos, mediante análise de ciclo de vida, ACV. A unidade funcional foi 1 Kg de brotos com boa qualidade para exportação. O estudo avaliou os sistemas de flores de corte desde a extração de matéria-prima até a comercialização do produto nos mercados de Londres e Miami, e analisou dois agroecosistemas: um deles certificado ambientalmente e outro não certificado. A fase de transporte a Londres gerou maiores impactos comparando-a com a de transporte a Miami, especialmente na categoria de câmbio climático (GWP100), com valores de 9,10E+00 e 2,51E+00 Kg CO2-eq*UF-1 para Londres e Miami, respectivamente. Ao considerar as fases prévias ao transporte, o sistema não-certificado gerou maior impacto que o certificado, especificamente por seu maior uso de fertilizantes (certificado 1,448E-02 Kg*UF-1, não-certificado 2,23E-01 Kg*UF-1) y defensivos (certificado 1,24E-04 Kg*UF-1, não-certificado 2,24E-03 Kg*UF-1). Considerando o manejo de cultivo, as categorias com maior carga ambiental foram eutroficação (EP) e acidificação (AP). Nos melhores cenários se observou que o transporte marítimo e a redução de 50% em uso de fertilizantes diminuem os impactos ambientais nesta cadeia de suprimento.]]></p></abstract>
