Propuesta silvícola y recolección sustentable para formaciones de maqui (Aristotelia chilensis Mol. (Stuntz) en la Región de Aysén (Chile)
Este estudio propone una metodología de recolección y manejo del recurso basado en buenas prácticas y toma en cuenta aspectos ecológicos y topográficos que afectan el grado de intervención de los macales, proporciona información valiosa sobre la superficie de macales en la Región de Aysén, su ubicación y las principales limitaciones ambientales. Al mismo tiempo, ofrece una propuesta de manejo silvicultural del macal, para una cosecha de frutos de maqui de manera sostenible en el tiempo sin comprometer la cobertura forestal, la variabilidad genética y entregar una alternativa productiva a los pequeños productores de la Región de Aysén.

Life Cycle Assessment of grain cropping
Life cycle assessment (LCA) is a relatively recent framework that was developed to estimate the environmental impacts of industrial production processes and systems. The framework is now being applied to agricultural systems, including cropping systems, to identify opportunities for more environmentallysustainable production. This purpose of this paper is to provide an overview of the application of LCA to grain cropping systems. Research at NSW DPI has focused on using LCA to estimate greenhouse gas (GHG) emissions from grain production systems for different regions of NSW as part of an industry-funded climate mitigation research program. The emission profiles suggest that GHG emissions in the systems modelled thus far are primarily the result of the production and application of synthetic N fertilizers, direct losses of nitrous oxide (N2O) via denitrification of soil mineral N and dissolution of lime. The emissions intensities of crops also differ between regions primarily due to rainfall patterns and soil type, the type of fertiliser used, levels of inputs and yields. LCA, however, can provide a more holistic view of environmental impacts by also estimating effects on indicators such as eutrophication, land-use change and ecological toxicity. The reporting of numerous indicators allows potential perverse impacts to be assessed from applications of potential mitigation strategies. For example, increasing the proportion of legumes in a cropping rotation may reduce GHG emissions for that land area. However, the action may also result in land-use change to maintain supply of products displaced by including legumes in the rotation. Emissions associated with this land-use change such as sequestration or emission of soil or biomass carbon, may also affect the overall environmental impact.

Climate impact of producing more grain legumes in Europe
The grain legumes pea and faba beans are among the relevant alternatives to imported soybeans for livestock feed for growing in the European agricultural systems, but what is the climate impact of an increased European production of grain legumes such as pea and faba bean? In order to estimate the overall climate impact of producing more grain legumes in Europe, we applied Life Cycle Assessment (LCA). The results showed that carbon footprints per kg protein of pea and faba bean in Europe did not vary much for different regions in Europe. Based on FAO statistics and an expert survey (Reckling et al., 2014), it was assumed that an increased European production of grain legumes will decrease the import of soybean cake and decrease the export of wheat from Europe. Taken that into account, results showed a small climate benefit of producing more grain legumes in Europe compared to importing soybeans to Europe.
