“…Crop production, food processing, and product marketing all generate GHG, contributing to global climate change (Dyer et al 2010). In 2008, agriculture in Canada produced approximately 62 million tonnes of CO 2 equivalent emissions, about 8% of Canada's total emissions (Environment Canada 2010).…”

“…En 2010, se estima que la agricultura representa la tercera actividad económica responsable de las emisiones de gases de efecto invernadero (GEI) con una producción anual de 4,6 Gt CO 2 e, lo que equivale al 14% de las emisiones mundiales (FAOSTAT, 2013). Los principales factores contribuyentes a las emisiones de GEI en la agricultura proceden de la transformación, mediante diversos procesos biológicos y físico-químicos presentes en el suelo, de los insumos de fertilizantes inorgánicos y de la materia orgánica (estiércol, compost, residuos vegetales) (Dyer et al, 2010). Estos procesos conllevan la producción de los tres principales GEI procedentes de la agricultura: N 2 O, CO 2 y CH 4 .…”

ResumenEl incremento de temperatura de nuestro planeta asociado al efecto invernadero antropogénico promueve interés por la búsqueda de estrategias de mitigación de gases de efecto invernadero. Puesto que la agricultura es un sector responsable de casi una quinta parte de las emisiones globales, es necesario identificar qué medidas podrían aplicarse, cuál es su potencial de mitigación y el coste estimado de la aplicación de cada medida. Nuestro estudio responde a estas preguntas comparando la producción de patata en dos sistemas productivos bien diferenciados y a partir de datos reales de campo. En una primera fase este trabajo calcula la huella de carbono en sistemas de producción modernos de la mecanización agrícola y el uso de energía para el riego (localizados en España) y en sistemas productivos que integran menos tecnologías (localizados en Perú). Los resultados muestran que en los casos de estudio de ambos países el ciclo de nitrógeno representa la primera fuente de emisiones de gases de efecto invernadero, seguido de energía para riego y combustible para la mecanización. Posteriormente este estudio evalúa las acciones de mitigación mediante el análisis económico de Curvas de Costes Marginales de Mitigación. Dichos resultados demuestran que el manejo del fertilizante nitrogenado es la mejor alternativa para reducir la huella de carbono debido a su mayor potencial de reducción de emisiones y menores costes de mitigación equivalentes. Finalmente el estudio aporta un marco metodológico que puede ser fácilmente aplicado a otros cultivos.Palabras clave: Curvas de costes marginales de mitigación, fertilización nitrogenada, coste-eficacia, riego. Abstract Economic evaluation of strategies for mitigating greenhouse gas emissions in potato production systemsThe temperature rise of the planet associated with anthropogenic greenhouse gas emissions promotes interest for strategies to mitigate them. Since agriculture is a sector responsible for nearly a fifth of global emissions, it is necessary to identify measures to be applied, what is their mitigation potential and the estimated cost of implementing each measure.

“…Agriculture involves the production of various crops, the process of various grain products, and the marketing of a variety of food products to the consumers; all these generate greenhouse gases (GHGs) (Dyer et al 2010). The emissions come from the combustion of fossil energy at various stages of a product's life cycle, giving rise to carbon dioxide (CO 2 ).…”

Purpose Best agricultural practices can be adopted to increase crop productivity and lower carbon footprint of grain products. The aims of this study were to provide a quantitative estimate of the carbon footprint of selected oilseed crops grown on the semiarid northern Great Plains and to determine the effects of N fertilization and environments on the carbon footprint.Materials and methods Five oilseed crops, Brassica napus canola, Brassica rapa canola, Brassica juncea canola, B. juncea mustard, and Sinapis alba mustard, were grown under the N rates of 0, 25, 50, 100, 150, 200, and 250 kg N ha −1 at eight environsites (location × year combinations) in Saskatchewan, Canada. Straw and root decomposition and various production inputs were used to calculate greenhouse gas emissions and carbon footprints. Results and discussion Emissions from the production, transportation, storage, and delivery of N fertilizer to farm gates accounted for 42% of the total greenhouse gas emissions, and the direct and indirect emission from the application of N fertilizer in oilseed production added another 31% to the total emission. Emissions from N fertilization were nine times the emission from the use of pesticides and 11 times that of farming operations. Straw and root decomposition emitted 120 kg CO 2 eq ha −1 , contributing 10% to the total emission. Carbon footprint increased slightly as N rates increased from 0 to 50 kg N ha −1 , but as N rates increased from 50 to 250 kg N ha −1 , carbon footprint increased substantially for all five oilseed crops evaluated. Oilseeds grown at the humid Melfort site emitted 1,355 kg CO 2 eq ha −1 , 30% greater than emissions at the drier sites of Scott and Swift Current. Oilseeds grown at Melfort had their carbon footprint of 0.52 kg CO 2 eq kg −1 of oilseed, 45% greater than that at Scott (0.45 kg CO 2 eq kg −1 of oilseed), and 25% greater than that at Swift Current (0.45 kg CO 2 eq kg −1 of oilseed). Conclusions Carbon footprint of oilseeds was a function of the rate of N fertilizer, and the intensity of the functionality varied between environments. Key to lower carbon footprint in oilseeds is to improve N management practices.
