Bioenergy is an important component of the renewable energy mix, helping to ensure a stable energy supply. One of the alternatives for bioenergy production is the use of Eucalypts sp. grown on short rotation coppice under different harvest systems. Because in some cases all components of the tree are harvested, there could be implications regarding the sustainability of this type of system. For this reason, new information is required to assess this alternative energy source. The objective of the research was to estimate the biomass production, energy yield, nutrient concentration, nutrient removal, and energy yield per kg of nutrient removal (EYNR) of four years old E. dunnii using two initial planting densities (3 m×1.5 m and 3 m×0.75 m) into two different
sites comparing two harvest systems; stemwood without debarking (System A) vs whole tree (System B). There was no impact of the planting density on the biomass production and energy yield per hectare. Significant differences of nutrient concentrations in different tree components were observed, but generally with similar magnitude between the two densities. The magnitude of nutrients removal caused by forest biomass varied depending on the nutrient, tree component, and biomass production. For the biomass production, energy yield, nutrient removal per hectare and EYNR system B was always significantly higher than system A. According to these results system B is more efficient from the energy yield perspective, but less sustainable from the soil
fertility point of view. MenosBioenergy is an important component of the renewable energy mix, helping to ensure a stable energy supply.

In Uruguay, livestock production involves 65% of the family farmers and more than 70% of the area of the country. Low levels of sustainability were diagnosed in livestock family farming systems based on natural grasslands in Uruguay, being the main causes low meat yield and income. Scientific evidence shows that it is possible to increase production while preserving natural resources and enhancing ecosystem services through changes in management practices of pastures and animals (Nabinger et al., 2011). However, during the last decades low levels of technological innovation has been applied in livestock systems. Lack of improvement by farmers could be explained by the weakness and the traditional approach of the extension service. From a traditional approach, innovations are designed externally to the systems and farmers adopt those innovations by an “extension” process. Extension linearly involves awareness of the problem by the farmer, interest in the solution, evaluation, experimentation and finally adoption (Cramb, 2000). Nevertheless, the active participation of the farmers in the diagnosis and redesign might maximize the impact of the proposals generated, promoting learning processes that support innovation in practices in the long term (Leeuwis & Van der Ban, 2004). The co-innovation approach combines complex systems theory, social learning and dynamic project monitoring and evaluation to stimulate strategic re-orientation of family farm systems (Rossing et al., 2010). We hypothesized that a systemic and participative approach such as this one is necessary for re-designing productive systems in order to improve their sustainability, being the learning process in farmers as important as the bio-physical changes in their production systems.
