Análisis general de sistemas productivos claves y sus indicadores a nivel nacional en el contexto de crecimiento verde

El concepto de crecimiento verde fue incluido en el Plan Nacional de Desarrollo 2014-2018 “Todos por un Nuevo País” con el objetivo de buscar el desarrollo económico sostenible, la competitividad y la reducción de vulnerabilidades al cambio climático. En este informe se busca dar a conocer el estado actual de los indicadores de crecimiento verde para diferentes sistemas productivos agropecuarios en Colombia e identificar las opciones tecnológicas que permitan mejorar dichos indicadores con el fin de incrementar la productividad de la tierra sin afectar los demás indicadores de crecimiento verde. Para lograr esto se han propuesto en este estudio cinco fases que van desde la fase de preparación, un análisis general a nivel nacional, un análisis detallado a nivel regional, un análisis de barreras para la implementación de medidas y recomendaciones. Este reporte corresponde a la fase dos del estudio sobre análisis general. La línea base de expansión en área proyectada para los cinco sistemas productivos, la construcción y estimación de los indicadores a nivel nacional para cada uno de los sistemas productivos y una lista de opciones tecnológicas que pueden contribuir al crecimiento verde en estos sistemas productivos. Posteriormente se estimará el potencial que tiene cada tecnología sobre los indicadores de crecimiento verde. En este estudio también se incluye la metodología y resultados sobre el proceso de priorización de los sistemas productivos. The concept of green growth was included in the National Development Plan 2014-2018 "All for a New Country" with the objective of seeking sustainable economic development, competitiveness and the reduction of vulnerabilities in climate change. This report seeks to publicize the current status of green growth indicators for different agricultural production systems in Colombia and identify the technological options that allow improving the indicators in order to increase the productivity of the land without affecting the other indicators of green growth To achieve this, five phases have been improved in this study, ranging from the preparation phase, a general analysis at the national level, detailed analysis at the regional level, an analysis of barriers to the implementation of measures and recommendations. This report corresponds to the phase of the study on general analysis. The baseline projected in this area for the five productive systems, the construction and the estimation of the indicators at national level for each one of the productive systems and a list of technological options that can contribute to the green growth in these productive systems. Subsequently, the potential of each technology on green growth indicators will be estimated. This study also includes the methodology and results on the process of prioritization of productive systems.The concept of green growth was included in the National Development Plan 2014-2018 "All for a New Country" with the objective of seeking sustainable economic development, competitiveness and the reduction of vulnerabilities in climate change.

THE GEOMORPHOLOGICAL DISTRIBUTION OF SUBAQUEOUS TUFA COLUMNS IN A HYPERSALINE LAKE: MONO LAKE, U.S.A.

Understanding the flow of carbon through hyperalkaline lakes is a key means of understanding their biogeochemistry, sedimentology, and their paleoenvironmental and paleoclimatic records. Furthermore, understanding how mineral precipitation is regulated in these lakes can provide insights into how their sequestration of carbon can be managed. We report geophysical surveys of Mono Lake, California, USA, which show unanticipated geomorphological control on the recent/contemporary formation of lacustrine carbonate formations (‘‘tufa’’). Acquired shallow-penetration seismic data show a fault zone below the lake floor, but despite the regional evidence for geothermal waters rising up these fractures, we find no evidence for tufa precipitation at the surface exposure of this structure, either in the seismic data or in the swath bathymetry. However, we do find sub-lacustrine tufa columns in these data elsewhere, which is the first time these have been reported directly. We find and report on a strong link between column location and meteoric Ca supply to the lake, with the latter sourced either through surface runoff or groundwater. For example, a region close to a creek inlet has more frequent and larger tufa bodies, which grow at a wider depth range than another region far from an inlet but close to the fault. This demonstrates the importance of meteoric water ingress in regulating carbonate mineral formation in these basins, and raises the possibility that management of water within the catchment could be a means to enhance carbon capture in natural and artificial hyperalkaline lakes
