Channeling Water Conflicts through the Legislative Branch in Colombia

This paper answers the question: has the Colombian Congress been effective at addressing relevant water conflicts and making them visible? While courts and social movements have been key for the advancement of social rights in Latin America, the role of legislators remains unclear. We conduct content analysis of all water-related bills, proposed bills, and constitutional amendments filed in Colombia from 1991 to 2020; we also analyzed Congress hearings of political control related to water, and the statutes of political parties who hold majority of seats in Congress; we also conducted interviews with key actors on water governance in Colombia. We find that only three bills have passed in the 30-year time frame and that relevant water conflicts have not been addressed by Colombian legislators. We find that water conflicts are not reaching the political agenda of Congress, yet through political control hearings, it has given some late visibility to critical territorial conflicts in which water is a key element. We analyze our data in light of literature on legislative politics and legal mobilization in Latin America. This study adds to global research on the role of legislators in advancing the human right to water, particularly in Latin America.publishedVersio

Comparing Experiences of Constitutional Reforms to Enshrine the Right to Water in Brazil, Colombia, and Peru: Opportunities and Limitations

In this paper we compare recent efforts towards the constitutionalization of the right to water in Brazil, Colombia, and Peru to understand the opportunities and limitations related to the attempts to enhance access to piped water to the highest normative level. Peru passed a constitutional amendment in 2017 while Brazil and Colombia have seen much right-to-water activism but have not succeeded in passing such reforms. We explore the role of the existing domestic legal frameworks on drinkable water provision and water management towards the approval of constitutional amendments. We find that all three countries have specialized laws, water governing institutions, and constitutional jurisprudence connecting access to water with rights, but the legal opportunity structures to enforce socio-economic rights vary; they are stronger in Colombia and Brazil, and weaker in Peru. We argue that legal opportunity structures build legal environments that influence constitutional reform success. Legal opportunity structures act as incentives both for social movements to push for reforms and for actors with legislative power to accept or reject them. Our findings also show that in some contexts political cost is a key element of constitutional reforms that enshrine the right to water; therefore, this is an element that should be considered when analyzing these processes

Factores de riesgo para trastornos de la alimentación en los alumnos de la Universidad de Manizales

ResumenObjetivo: Determinar la frecuencia de los factores de riesgo para trastornos de la alimentación en estudiantes de la Universidad de Manizales. Materiales y métodos: De 3,610 estudiantes regulares de la Universidad  de Manizales se tomó una muestra de 165 estudiantes, quienes respondieron un cuestionario integrado compuesto por variables demográficas, las escalas de Zung para ansiedad o depresión,el Eating Disorderrs Inventory (EDI2) y el Apgar familiar; además se tomaron las medidas de peso, talla, índice de masa corporal y pliegue en el antebrazo. Resultado: Un12.7% de la población presentó factor de riesgo positivo para trastornos de la conducta alimentaría, 17.3% de la población femenina y el 3.8% de la población masculina; las personas con mayor factor de riesgo fueron las mujeres en la facultad de Comunicación Social y Periodismo (24.1%). Se determinó una  relación significativa entre la variable impulso por la delgadez con la ansiedad o depresión. El mayor índice de masa corporal y de porcentaje de grasa está asociado con un aumentoen la variable impulso por la delgadez. Conclusiones:Se encontraron factores de riesgo asociados con trastornos de la alimentación. La frecuencia del factor de riesgo según EDI2 en este estudio fue más baja que la encontrada en estudios realizados en Medellín y Bogotá.[Cano AA, Castaño JJ, Corredor DA, García AM, González M, Lloreda OL, et al.

estudos artísticos

Como é característica fundadora do projeto CSO – criadores sobre outras obras – os artistas são aqui convidados a comunicar o seu conhecimento sobre outros artistas, dentro de um descentramento que toma os idiomas ibéricos como uma plataforma territorial de emergência, e de resistência, também. É uma área cultural periférica, alternativa, que se afirma em crescente grandeza. Dentro deste dispositivo comunicativo, a revista Croma delimita mais ainda o seu tema, nos artistas que de algum modo fazem incorporar a implicação social, a interação e a criação e formação de novos públicos como um dos componentes estruturantes da sua obra. Surgem na Croma obras intervenientes, que provocam, e que convocam, que estabelecem pontes, ou que as ameaçam. São obras em que a componente relacional (N. Bourriaud) ou formativa e integradora (P. Freire) assumem uma atualidade constante e renovada. Os artigos reunidos neste quinto número da Revista Croma propõem, no seu conjunto uma intenção de proximidade, de confronto com realidades, de inconformismo, de procura e de questionamento identitário. Dos seus múltiplos países e das suas diversificadas abordagens a variadas técnicas, os vinte e cinco artigos aqui apresentados complementam o poder do desassossego e da inquietação poética: os artistas falam connosco, através de outros artistas, que os souberam ver e ouvir.info:eu-repo/semantics/publishedVersio

Demografía y ecología de anidación de la iguana verde, Iguana iguana (Squamata: Iguanidae), en dos poblaciones explotadas en la Depresión Momposina, Colombia

Se estudió la demografía y ecología de anidación de dos poblaciones de Iguana iguana que enfrentan explotación severa y alteración del hábitat, en la Depresión Momposina, Colombia. Los atos de transectos lineales fueron analizados con el modelo de Fourier para estimar la densidad de grupos sociales. El tamaño promedio de grupo y la densidad general de iguanas varió dentro y entre poblaciones (1.05 - 6.0 grupos/ha, y 1.5 - 13.7 iguanas/ha respectivamente). Las estimaciones de densidad fueron mucho menores que las reportadas en áreas más protegidas en Panamá y Venezuela. Las densidades de las iguanas fueron considerablemente mayores en sitios localizados a lo largo de los ríos (2.5 iguanas/grupo) que en sitios en el margen de las ciénagas (1.5 iguanas/grupo), probablemente debido a diferencias en la vegetación. No hubo correlación entre las estimaciones de densidad y la de abundancia relativa (número de iguanas vistas/hora/persona), debido a diferencias en detectabilidad de los grupos de iguanas entre los sitios. La proporción sexual hallada (1:2.5 machos: hembras), es probablemente el resultado del sistema de apareamiento polígamo de esta especie, en vez de indicar un verdadero sesgo demográfico. Se monitoreó 34 nidos los cuales sufrieron poca depredación por vertebrados. Sin embargo si fueron afectados por inundaciones, pisoteo por ganado e infestación por larvas de mosca Phoridae. El tamaño de huevos por nidada en estas poblaciones fue de 29.4 menor que cualquier otro reporte de la literatura, con la excepción de las poblaciones de Iguana que habitan la isla altamente xérica de Curaçao, implicando que las hembras adultas en nuestra área son inusualmente pequeñas. Probablemente éste es el resultado de la explotación prolongada y excesiva de estas poblaciones en vez de ser una respuesta adaptativa a condiciones ambientales extremas.We studied the demography and nesting ecology of two populations of Iguana iguana that face heavy exploitation and habitat modification in the Momposina Depression, Colombia. Lineal transect data was analyzed using the Fourier model to provide estimates of social group densities, which was found to differ both within and among populations (1.05 - 6.0 groups/ha). Mean group size and overall iguana density estimates varied between populations as well (1.5 -13.7 iguanas/ha). The density estimates were far lower than those reported from more protected areas in Panama and Venezuela. Iguana densities were consistently higher in sites located along rivers (2.5 iguanas/group) than in sites along the margin of marshes, probably due to vegetational differences (1.5 iguanas/group). There was no correlation between density estimates and estimates of relative abundance (number of iguanas seen/hour/person) due to differing detectabilities of iguana groups among sites. The adult sex ratio (1:2.5 males:females) agreed well with other reports in the literature based upon observation of adult social groups, and probably results from the polygynous mating system in this species rather than a real demographic skew. Nesting in this population occurs from the end of January through March and hatching occurs between April and May. We monitored 34 nests, which suffered little vertebrate predation, perhaps due to the lack of a complete vertebrate fauna in this densely inhabited area, but nests suffered from inundation, cattle trampling, and infestation by phorid fly larvae. Clutch sizes in these populations were lower than all other published reports except for the iguana population on the highly xeric island of Curaçao, implying that adult females in our area are unusually small. We argue that this is more likely the result of the exploitation of these populations rather than an adaptive response to environmentally extreme conditions

Microgeographic body size variation in a high elevation Andean anole (Anolis mariarum; Squamata, Polychrotidae)

Intra-specific body size variation is common and often is assumed to be adaptive. Studies of body size variation among sites should include or consider environmental and ecological variables in their designs. Additionally, reciprocal transplant or common garden studies will support which variables are really contributing to the observed body size variation. This study analyzed the microgeographic body size variation in Anolis mariarum, a small lizard endemic to Antioquia, Colombia. Parameters such as body size, shape, and lepidosis variation were quantified in 217 adult A. mariarum, belonging to six populations separated by less than 80km. Results showed that significant body size variation was not related to differences among sites in mean annual temperature, but covaried with mean annual precipitation, with the largest individuals occurring in dryer sites. Mark-recapture data obtained from 115 individuals from both the wettest and dryest sites from October 2004 to April 2005 showed that growth rates were higher at the latter. Eight males from each site were captured at the end of the mark- recapture study and reared for two months under identical conditions in a common garden study. Individuals from both sites grew faster when reared in the laboratory with food provided ad libitum. Although growth rates of males from the two populations did not differ significantly in the laboratory, males from the dryest site still maintained a significantly larger asymptotic body size in their growth trajectories. Multivariate analyses also demonstrated that both males and females from the six populations differed in terms of body shape and lepidosis. However, only female body size was found to covary significantly with an environmental gradient (precipitation). A. mariarum does not conform to Bergmann’s rule, but the relationship found between mean body size and asympotic growth with mean annual precipitation at these sites needs further analysis. Generally, studies of intra-specific body size variation should consider a number of additional phenotypic traits to provide stronger baseline information on the degree of overall divergence among populations, including those likely to be selectively neutral, before interpreting results of analyses on the body size differences.

Epub 2009 December 01.<br>Se reporta diferencias en el tamaño corporal entre individuos adultos de seis poblaciones de Anolis mariarum (Squamata: Polychrotidae), separadas por una distancia de hasta 80km. Esta variación no se relacionó con las diferencias en las temperaturas promedio anuales que existen entre los sitios analizados, pero sí covarió con la precipitación promedio anual, con los individuos de mayor talla habitando los sitios más secos. Datos de marca- recaptura del sitio más seco y más húmedo, mostraron que los individuos del sitio más seco tienen mayores tasas de crecimiento corporal. Bajo condiciones de laboratorio con alimento ad libitum, machos de ambos sitios crecieron más rápido que en condiciones naturales. Aunque las tasas de crecimiento de machos de las dos poblaciones no difirieron significativamente en el laboratorio, los machos del sitio más seco mantuvieron tamaños corporales asintóticos en sus trayectorias de crecimiento que fueron significativamente mayores. Análisis multivariados mostraron que tanto los machos como las hembras de las seis poblaciones difieren en la forma corporal y en lepiodosis, pero la única variable que covarió de manera significativa con un gradiente ambiental fue el tamaño corporal con la precipitación. Estudios de variación intraespecífica en el tamaño corporal deben considerar otras características fenotípicas adicionales para obtener una línea base sobre el grado de divergencia entre poblaciones, incluso aquellas que se consideran neutrales
