SEPIA XVII Mesa Tematica: Experiencias latinoamericanas de aplicacion del enfoque de cadenas de valor inclusivas.
Esta publicación incluye tres presentaciones realizadas en la Mesa Temática denominada “Experiencias latinoamericanas en la aplicación del enfoque de cadenas de valor inclusivas”, en el marco del SEPIA XVII. Como introducción se realiza un balance de los aportes que se discutieron en la Mesa Temática y una proyección de sus implicancias. Las experiencias mostradas abren una perspectiva valiosa para la investigación sobre los casos de aplicación del enfoque de cadenas de valor, la cual debe ser promovida en los siguientes años como base para el escalamiento en políticas más amplias que promuevan el desarrollo rural
Hydraulic properties of soil cores from untrafficked and trafficked areas
The hydraulic conductivity is an important soil parameter that is both difficult and time consuming to measure directly. Several methods have been proposed to estimate soil hydraulic conductivity indirectly. This paper focuses on one method of predi.:ting hydraulic conductivity from knowledge of the soil water retention curve. Water retention curves were measured for 15 undisturbed soil cores. Unsaturated hydraulic conductivity of the same 15 soil cores also was determined directly by using unit gradient measurements. An equation was fitted to each of the retention curves, and a procedure using the fitting parameters was implemented to predict hydraulic conductivity of each core. Predicted and observed hydraulic conductivities are compared. The procedure describes hydraulic conductivity relationships better when observed values of unsaturated hydraulic conductivity are included in the curve fitting process, than when the saturated hydraulic conductivity alone is used as a matching point. Analysis of a data set taken from the literature indicates that observed air permeabilities may also be useful for estimating the unsaturated hydraulic conductivity
Soil moisture and evapotranspiration predictions using Skylab data
The author has identified the following significant results. Multispectral reflectance and emittance data from the Skylab workshop were evaluated for prediction of evapotranspiration and soil moisture for an irrigated region of southern Texas. Wavelengths greater than 2.1 microns were required to spectrally distinguish between wet and dry fallow surfaces. Thermal data provided a better estimate of soil moisture than did data from the reflective bands. Thermal data were dependent on soil moisture but not on the type of agricultural land use. The emittance map, when used in conjunction with existing models, did provide an estimate of evapotranspiration rates. Surveys of areas of high soil moisture can be accomplished with space altitude thermal data. Thermal data will provide a reliable input into irrigation scheduling

Collinear investigation of laser initiated reduced density channels
The characteristics of reduced density channels generated by laser initiated discharges have been investigated by means of collinear holographic interferometry and schlieren photography. We report the first direct measurements of the density profiles in the interior of such channels. Under unperturbed conditions these channels exhibit azimuthal asymmetries. Gas dynamics within the channel are also presented for the case of incident shock waves reflected from cylindrical and planar boundaries.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71306/2/APPLAB-43-11-1010-1.pd
