| dc.description.abstract | Colombia is the second-largest exporter of flowers in the world. The major
production hub is placed around the capital city, Bogota. Approximately 7266 ha are
devoted to production of ornamental species under greenhouse conditions, the most
important being roses (Rosa spp.) and carnations (Dianthus caryophyllus). Concern
about the environmental performance of the industry is growing among the
international market. The aim of this work was to explore technological alternatives
to reduce the environmental impact exerted by the supply chain (production,
marketing and consumption) of cut roses under greenhouse but at the same time
looking for a production model that improves actual yields. The Life Cycle
Assessment method was used to evaluate the environmental performance of the
actual production system as well as a proposed technological alternative. The supply
chain was divided into three stages: 1. cropping system including infrastructure, pest
management, fertilization, harvest and residues; 2. postharvest including grading,
packaging and storage and, 3. transportation to markets in the United States. The
number of rose stems produced per square meter of soil was defined as the
functional unit. Addition of a heating system to the actual cropping system in order
to increase yields and reduce pest incidence was considered. Previous studies have
shown that transportation of the flowers by aircraft imposes the major
environmental impact by the product. Alternative transportation by ship is
discussed in the present study. Results indicated the feasibility of including heating
systems actual production schemes due to increase in energy use efficiency. In the
overall impact assessment, this alternative will reduce the environmental impact of
the actual cropping system. This study demonstrated that technological
improvements to the supply chain can result in environmental benefits in order to
preserve the competitiveness of the flower industry in Colombia. | |
