ABSTRACT:
Grasslands are one of the most modified biomes on Earth. Land use changes had a large impact on carbon (C) stocks of grasslands. Understanding the impact of land use/land cover changes on C stocks and fluxes is critical to evaluate the potential of rangeland ecosystem as C sinks. In this article we analyze C stocks and fluxes across the environmental gradients of one of the most extensive temperate rangeland areas: the Rio de la Plata Grasslands (RPG) in South America. The analysis summarizes information provided by field studies, remote sensing estimates, and modeling exercises. Average estimates of aboveground net primary production ( ANPP) ranged from 240 to 316 gC · m~2 · yr"1. Estimates of belowgro und NPP(BNPP) were more variable than ANPP and ranged from 264 to 568 g C · m~2 · yr"1. Total Carbon ranged from 5 004 to 15 008 g C · m~2. Plant biomass contribution to Total Carbon averaged 13 % and varied from 9.5% to 27% among sites. The largest plant C stock corresponded to belowground biomass. Aboveground green biomass represented less than 7% of the plant C. Soil organic carbon (SOC) was concentrated in the slow and passive compartments of the organic matter. Active soil pool represented only 6.7% of the SOC. The understanding of C dynamics and stocks in the RPG grasslands is still partial and incomplete. Field estimates of ANPP and BNPP are scarce, and they are not based on a common measurement protocol. Remotely sensed techniques have the potential to generate a coherent and spatially explicit database on ANPP. However, more work is needed to improve estimates of the spatial and temporal variability of radiation use efficiency. The absence of a flux tower network restricts the ability to track seasonal changes in C uptake and to understand fine-scale controls of C dynamics. MenosABSTRACT:

Se llevó a cabo un estudio de caso enmarcado en un proceso de investigación cualitativa, en torno a la Mesa de Desarrollo Rural de Laureles-Cañas, Tacuarembó. Para ello se utilizaron métodos cualitativos de investigación social como entrevistas abiertas estandarizadas y mapeo de actores sociales. La primera conclusión es que no existe una metodología pre-establecida para el trabajo en las MDR. Por otro lado, se identifica una visión enmarcada en el desarrollo rural con enfoque territorial. Otra de las conclusiones es que existen importantes actores del medio que no participan de las MDR, como las empresas forestales o los asalariados rurales. Asimismo, se dentificó la relevancia de los liderazgos locales y que existen ciertos problemas de representatividad de los delegados. Se establece un lineamiento sugerido de
trabajo en las MDR mediante capacitaciones, mapeos de actores y establecimiento claro del ámbito como tal. Abstract: A case study was carried out within a qualitative investigation process, concerning the Laureles-Cañas Rural Development Round Table (MDR), in Tacuarembó. Qualitative Methods of Social Investigation were used, such as open standardized interviews and mapping of social actors. The first conclusion arrived at is that there is no previously stated methodology in order to work with the MDRs. On the other hand, the Territorial Rural Development Scope was identified as the main vision implied in these Round Tables. Another conclusion arrived at was that there are relevant social actors that do not participate in these meetings, such as forestry companies or wage earners. Furthermore, local leaderships
were identified to be of relevant importance and it was also identified that there are certain representative issues. It is suggested that these MDR should use training methodologies, mapping of social actors and the clarifying of the aim of these meetings.
