Los Jefes de Estado y de Gobierno y los Representantes Especiales de Brasil, China, así como Costa Rica, Cuba, Ecuador, Antigua y Barbuda, también miembros del Cuarteto de CELAC – y Argentina, Bolivia, Chile, Colombia, Guyana, México, Paraguay, Perú, Surinam, Uruguay y Venezuela, realizamos una reunión en Brasilia, el 17 de julio de 2014, bajo el tema “Igualdad y Beneficio Mutuo, Cooperación Recíproca y Desarrollo Común”, emiten una declaración conjunta reconociendo que el mundo está experimentando por un proceso de globalización económica y cambio político y que nuestros países tienen un rol clave que desempeñar contribuyendo a la paz, la estabilidad, el crecimiento inclusivo y el desarrollo sostenible, la prosperidad y para la forja de un mundo multipolar.

La política exterior de China hacia América Latina : un análisis de la relación de China y Colombia (periodo 2010-2015)

Esta monografía tiene como objetivo analizar la política exterior de China hacia América Latina en materia económica, política y cultural, con énfasis en las relaciones con Colombia, durante el periodo de 2010 a 2015. Los conceptos de Soft Power y desarrollo pacífico son centrales en el estudio porque sirven para entender la proyección de la política exterior china y cómo mediante ello pretende posicionar una mayor influencia en la región. El trabajo es de tipo analítico, porque identifica la política exterior china y su alcance.

Latin America and the Caribbean and China: towards a new era in economic cooperation

Foreword by Alicia Bárcena

Toward sustainable soil and water resources use in China`s highly erodible semi-arid loess plateau

The water-wind crisscross region of the Loess Plateau in China is comprised of 17.8 million hectares of highly erodible soil under limited annual rainfall. This requires a sustainable water balance for the restoration of dryland ecosystems to reduce and manage soil erosion. In this region, alfalfa has been one of the main legumes grown to minimize soil erosion. However, alfalfa yields were significantly lower in years of reduced rainfall suggesting that high water use and deep rooting alfalfa make it an unsustainable crop due to the long-term decline in soil water storage and productivity. Our objectives in this Study were to evaluate the soil water balance of Loess Plateau soils during vegetative restoration and to evaluate practices that prevent soil desiccation and promote ecosystem restoration and sustainability. Field observations of soil moisture recovery and soil erosion were carried out for five years after alfalfa was replaced with different crops and with bare soil. Soil water content changes in cropland, rangeland, and bare soil were tracked over several years, using a water balance approach. Results indicate that growing forages significantly reduced runoff and sediment transport. A forage-food-crop rotation is a better choice than other cropping systems for achieving sustainable productivity and preventing soil erosion and desiccation. However, economic considerations have prevented its widespread adoption by local farmers. Alternatively, this study recommends consideration of grassland crops or forest ecosystems to provide a sustainable water balance in the Loess Plateau of China. (C) 2009 Elsevier B.V.

Impacts of land-use pattern on soil water-content variability on the Loess Plateau of China

Long-term vegetation restoration carried out on the slopes of the Loess Plateau of China employed different spatial and temporal land-use patterns but very little is known about the effects of these patterns on soil water-content variability. For this study the small Donggou catchment was selected to investigate soil water-content distributions for three spatial scales, including the entire catchment area, sampling transects, and land-use systems. Gravimetric soil water contents were determined incrementally to a soil depth of 1.20 m, on 10 occasions from April to October, 2007, at approximately 20-day intervals. Results indicated that soil water contents were affected by the six land-use types, resulting in four distinct patterns of vertical distribution of soil moisture (uniform, increasing, decreasing, and fluctuating with soil depth). The soil water content and its variation were also influenced in a complex manner by five land-use patterns distributed along transects following the gradients of five similar slopes. These patterns with contrasting hydrological responses in different components, such as forage land (alfalfa)-cropland-shrubland or shrubland-grassland (bunge needlegrass)-cropland-grassland, showed the highest soil water-content variability. Soil water at the catchment scale exhibited a moderate variability for each measurement date, and the variability of soil water content decreased exponentially with increasing soil water content. The minimum sample size for accurate data for use in a hydrological model for the catchment, for example, required many more samples for drier (69) than for wet (10) conditions. To enhance erosion and runoff control, this study suggested two strategies for land management: (i) to create a mosaic pattern by land-use arrangement that located units with higher infiltration capacities downslope from those with lower soil infiltrabilities; and (ii) raising the soil-infiltration capacity of units within the spatial mosaic pattern where possible.
