Acta Agronómica , 2009,
Abstract: to evaluate the impact of different land use systems for long periods of time on soil structural properties, a sampling to 0-20 cm of depth was carried in the following treatments: forest 25% slope (control), pasture crops for 25 years with 25% slope and use agricultural wheat-corn (rw-c) of 25, 45 and 70 years of use, each one of these last, with 12% and 25% slope, in a inceptisol (dystric haplustepts) of the area of reconversion of the wheat cropping area located at 2.400 to 2.800 masl in the andean zone of the department of nari?o, colombia (longitude 75o 14' west, latitude 0.5o 10' north, 2710 msnm, 80% rh, 12oc). results showed significant differences between the type and intensity of soil use for long periods of time in aggregate size distribution, aggregate stability and pore size distribution. the increment of the intensity of soil use, decreased its structural stability and affected soil porosity. the percentage of water stable aggregates larger than 2.0 mm was significantly higher in not intervened soil. the control had 51.5% of water stable aggregates larger than 2.0 mm. change to agricultural use (rw-c) during 25,45 and 70 years, decreased the stable aggregates larger than 2.0 mm, to 36.9%, 35.3%y 29.1% respectively. the change of forest to pasture, decreased the total porosity in 18%. the agricultural use (rw-c) through the time, generated gradual decrease of the total porosity.

Identidad de género: obstáculo al desarrollo o un acceso a la equidad?
Ximena Natalia Onega Delgado,Ana Cristina Delgado Zambrano
Revista CS , 2009,
Abstract: A partir de una investigación realizada entre adolescentes en el corregimiento de Catambuco (Nari o, Colombia), este artículo expone y reflexiona sobre las representaciones sociales de identidad de género que imperan en las aclitudes y creencias de este segmento poblacional. De esta forma, las autoras reconocen la presencia de estereotipos, opiniones, valores y normas que forman el significado del "ser y estar" en el mundo como hombre y como mujer, y discuten las implicaciones que tales representaciones sociales tienen sobre la equidad de género.

Abstract:

Objective: To evaluate the nutritional situation by anthropometry of the rural families population aged 0 to 64 years in the municipalities of Pasto, Túquerres, Guachucal, Cumbal and Cuaspud in the Nari?o Department (Colombia). Materials and Methods: As part of the research “Improving potato production as a food security contribution of native communities in Nariño, Colombia”, aged October and December in 2013, an initial diagnosis of the food security situation in farmer families was conducted, through direct visits to the households selected in the sample, where in the household members, after standardization of field team, the anthropometric measures of weight and height were taken, using electronic scales, infantometers and stadiometers. Conclusions: A significant stunting was reported in children up to 7 years. In children aged 0 - 5 years group and children aged 5 - 17 years group, the results exceed by more than double the department data (according to National Survey of the Nutritional Situation in Colombia ENSIN 2010), and almost three times the national data. The underweight was generally low in all the analysed groups, although concerned the significant overweight percentage. In children aged 0 - 5 years group, the overweight data (above 2 SD) exceeded twice the department and national data according to the ENSIN 2010, although in the children aged 5 - 17 years group, the overweight and obesity was lower than the departmental and national data. In adults, the results reported that one of each two people in the range of 18 to 64 years in the five municipalities had excess weight (overweight or obesity) which was similar data respected to the department and national data. Additionally, it was noted that 18% of households were found among adults with overweight, and simultaneously, children with stunting, this situation has been called double burden of malnutrition and this is an aspect that must be analysed to identify intervention strategies.

PROPIEDADES DEL SUELO EN BOSQUE Y PAJONAL; RESERVA NATURAL PUEBLO VIEJO, NARI O, COLOMBIA SOIL PROPERTIES IN FOREST AND GRASSLANDS; PUEBLO VIEJO NATURAL RESERVE, NARI O, COLOMBIA

Revista U.D.C.A Actualidad & Divulgación Científica , 2009,
Abstract: Se realizó un estudio exploratorio con el objetivo de comparar algunas propiedades químicas, físicas y biológicas de los suelos con cobertura en bosque de ladera (Bosque1), bosque en la vertiente del cauce de agua (Bosque2) y Pajonal, situados a similar altura, en la Reserva Natural Pueblo Viejo (Nari o). Se tomaron tres muestras de suelo por cada sitio, para un total de nueve muestras. Los datos, se procesaron mediante pruebas no paramétricas y Análisis de Componentes Principales. Se presentan diferencias estadísticas significativas entre Bosque2 y Pajonal, en C, N, CIC y Al, densidad aparente y densidad de Mollusca y, entre Bosque1 y Pajonal, en Mn y Cu. El análisis multivariado diferencia tres grupos correspondientes a los tres sitios. An exploratory study was carried out in order to compare the chemical, physical and biological properties of vegetation-covered soils in ladder woodlands (Afforested area No.1), woodlands located in the drainage area of a water source (Afforested area No.2) and grassland, situated at the same altitude, in the "Pueblo Viejo" Nature Reserve. Three soil samples were taken in each location, with a total of nine samples. The data were processed using non-parametric tests and Principal Component Analysis. There are significant statistical differences between Afforested area No.2 and grassland of levels of C, N, CEC, Al, bulk density and density of Mollusca, and between grassland and afforested area No.1 in levels of Mn and Cu. The multivariate analysis considered three groups, corresponding to the three locations.
EFECTO DEL GRADIENTE ALTITUDINAL SOBRE ASPECTOS AUTOECOLóGICOS DE ESPELETIA PYCNOPHYLLA ssp. ANGELENSIS CUATREC. (ASTERACEAE) EN EL PáRAMO EL INFIERNILLO (NARI?O-COLOMBIA)

Actualidades Biológicas , 2007,
Abstract: some autoecological features of espeletia pycnophylla ssp. angelensis cuatrec. such as its demographic structure, population density, spatial pattern of dispersion, production of reproductive structures, adult morphometry and survivorship, were studied in an altitudinal gradient on a dry paramo of nari?o (colombia). hypothesis proposed by other authors about a linear effect caused by the elevation on these variables were completely rejected. the elevation induces an ecoclinal effect on population density, and this density correlates negatively with both production of reproductive structures and adult sizes. these results elucidate an unequivocal effect of density-dependence phenomena on population fitness. the intermediate zone of the altitudinal gradient exhibits a high population density, but on the other hand show reduced corporal adult sizes, minimal production of reproductive structures and the probability of juveniles reaching advanced ages is low. evidently, this intermediate elevation can have favorable ecological conditions for the seedling establishment, wich increments population densities at long term. we propose that other author's generalizations about the influence of elevation on the autoecology of these plants are limited, because the particular life and disturbance stories of paramos and the spatial, ecological and genetic isolating are explicative factors impossible to take away from the context. the demographic structure of the population fitted the logarithmic model, revealing its early regeneration state from the last fire event on 2003 and the similarity of the survivorship curves among every elevation, probed a high demographic stability.
