Abstract:
Water management impacts both methane (CH4) and nitrous oxide (N2O) emissions from rice paddy fields. Although controlled irrigation is one of the most important tools for reducing CH4emission in rice production systems it can also increase N2O emissions and reduce crop yields. Over three years, CH4 and N2O emissions were measured in a rice field in Uruguay under two different irrigation management systems, using static closed chambers: conventional water management (continuous flooding after 30 days of emergence, CF30); and an alternative system (controlled deficit irrigation allowing for wetting and drying, AWDI). AWDI showed mean cumulative CH4 emission values of 98.4 kg CH4 ha−1, 55 % lower compared to CF30, while no differences in nitrous oxide emissions were observed between treatments ( p > 0.05). No yield differences between irrigation systems were observed in two of the rice seasons ( p > 0.05) while AWDI promoted yield reduction in one of the seasons ( p< 0.05). When rice yield and greenhouse gases (GHG) emissions were considered together, the AWDI irrigation system allowed for lower yield-scaled total global warming potential (GWP). Higher irrigation water productivity was achieved under AWDI in two of the three rice seasons. These findings suggest that AWDI could be an option for reducing GHG emissions and increasing irrigation water productivity. However, AWDI may compromise grain yield in certain years, reflecting the importance of the need for fine tuning of this irrigation strategy and an assessment of the overall tradeoff between relationships in order to promote its adoption by farmers.

Since the nineteens, Uruguayan native forests have been protected by law and their utilization reduced to some scarce traditional uses if not literally left untouched in many cases. However, in the last years, discussions raised around the ecological significance and the socio-economic future of this natural patrimony and a new national strategy was designed with a quite wide stakeholders participation. In parallel, as part of a national prospective study, the government conducted a bioeconomy study, applied to both planted and native forests. Biorefinery, through the extraction of high-value molecules from non-wood products for green chemistry was identified as one of the challenging approaches to fulfill the expectations of the bioeconomy implementation in the country. This works reports the research advances obtained by the Forestry Department of the National Agricultural Research Institute (INIA-Uruguay) in the field of: (i) the identification, extraction and characterization of secondary metabolites of native forest species as a raw material for biomaterials production and (ii) the way to increase its production through high-value tree domestication for ex situ cultivation providing knowledge to improve the reproduction, growth and yield of promising forest species. Two target native forest species (Quillaja brasiliensis and Prosopis affinis) were systematically studied through an interdisciplinary agenda and with an interdisciplinary team, covering different steps from the field to the laboratory: bioprospecting, cutting and plant production in vitro, seedling propagation in nursery, laboratory extraction and characterization of secondary metabolites, industrial scaling up and diffusion and technology transfer.
