Problemas sociales convertidos en problemas ambientales: tres casos paradigmáticos en el agro de Misiones, Argentina

En el contexto del nuevo paradigma participativo de conservación, el ambientalismo se está tornando un campo desde donde se construye territorialidad, que conlleva una nueva forma de institucionalizar el territorio y manejarlo tanto por parte del Estado, como por agencias no gubernamentales ambientalistas y de desarrollo. En tal proceso, el ambientalismo se presenta como un medio eficaz de resolver conflictos sociales y territoriales. Aquí, es central el despliegue de un aparato institucional ambientalista que implica la presencia de nuevos actores, proyectos y discursos, y la redefinición de los que ya se encontraban presentes. En este trabajo analizaremos tres casos paradigmáticos en el agro de Misiones, Argentina. </p

Estilos de desarrollo sustentable en el norte de Misiones

This article provides an approach to the field of conservation and sustainable development in the north of Misiones. The centerpiece is the ways in which environmental agencies face projections and interventions conservation in buffer zones of Protected Natural Areas. The first characterizes the departments of General Manuel Belgrano Iguaçu and the beginnings of the formation of environmental governance. It then describes the main projects for the conservation and sustainable development stimulated by JICA (Japan International Cooperation Agency) and AECI (Spanish Agency for International Development). Specifically, the key features of "Project Cabureí" (JICA) and the designs produced by Araucaria XXI (AECI). For the signal., Problem sets considerations applicants who meet the local communities and environmental agencies.Este trabajo realiza un acercamiento a la esfera de la conservación y el desarrollo sustentable en el norte de Misiones. El eje central son los modos en que agencias ambientalistas encaran proyecciones e intervenciones conservacionistas em zonas de amortiguamiento de Áreas Naturales Protegidas. Al principio se esboza una caracterización de los departamentos de Iguazú y General Manuel Belgrano, así como de los inicios de la conformación de una gobernanza medioambiental.

Estilos de desarrollo, ideología e Intervención antrópica en Misiones (Argentina): Un análisis multidimensional y comparativo. 16H201

Esta es una continuación del Programa ECIS (Estudio Comparativo de los Impactos Sociales de los Grandes Proyectos de Desarrollo), constituído a partir del 2005 en el Programa de Ecología Humana (PEH). Los ejes convocantes para esta nueva etapa, son, en primer lugar, la compleción del análisis del Proyecto Yacyretá, que en el período anterior concretó la publicación de un volumen. Una segunda vertiente remite a la ideología de los movimientos sociales opuestos a la construcción de represas y a la concepción de desarrollo explícitas o implícitas en sus propuestos y su comparación con otros movimientos ecologistas (Córdoba). Asimismo, nos proponemos realizar estudios de campo de las prácticas agrícolas de los colonos asentados en áreas de la provincia incluidas en el proyecto de "corredor verde", con el objeto de analizar su compatibilidad o no con los modelos de "explotación sustentable" que se vienen manejando, así como analizar otros desarrollos recientes en el agro misionero. Finalmente, se contemplan estudios comparativos sobre desarrollo socioeconómico de minorías en la Patagonia argentina

Zero forcing and power domination for graph products

The power domination number arose from the monitoring of electrical networks, and methods for its determination have the associated application. The zero forcing number arose in the study of maximum nullity among symmetric matrices described by a graph (and also in control of quantum systems and in graph search algorithms). There has been considerable effort devoted to the determination of the power domination number, the zero forcing number, and maximum nullity for specific families of graphs. In this paper we exploit the natural relationship between power domination and zero forcing to obtain results for the power domination number of tensor products and the zero forcing number of lexicographic products of graphs. In addition, we establish a general lower bound for the power domination number of a graph based on the maximum nullity of the matrices described by the graph. We also establish results for the zero forcing number and maximum nullity of tensor products and Cartesian products of certain graphs

Steady-State Diffusion in a Spatially Varying Porous Medium: Data Sets

This repository contains the data associated with the paper "Steady-State Diffusion in a Spatially Varying Porous Medium" to be published in Advances in Water Resources. These data include the information and program scripts required to reproduce the results reported in the publication. In particular, the data set includes (1) COMSOL and MATLAB files to reproduce the simulations for Cases 1-4, (2) the files required to calculate the closure problem source terms for all four cases, (3) mesh files in open-source format providing the mesh used in the computations associated with the paper, (4) the data used to produce the figures in the paper

Six hundred years of South American tree rings reveal an increase in severe hydroclimatic events since mid-20th century

South American (SA) societies are highly vulnerable to droughts and pluvials, but lack of long-term climate observations severely limits our understanding of the global processes driving climatic variability in the region. The number and quality of SA climate-sensitive tree ring chronologies have significantly increased in recent decades, now providing a robust network of 286 records for characterizing hydroclimate variability since 1400 CE. We combine this network with a self-calibrated Palmer Drought Severity Index (scPDSI) dataset to derive the South American Drought Atlas (SADA) over the continent south of 12°S. The gridded annual reconstruction of austral summer scPDSI is the most spatially complete estimate of SA hydroclimate to date, and well matches past historical dry/wet events. Relating the SADA to the Australia–New Zealand Drought Atlas, sea surface temperatures and atmospheric pressure fields, we determine that the El Niño–Southern Oscillation (ENSO) and the Southern Annular Mode (SAM) are strongly associated with spatially extended droughts and pluvials over the SADA domain during the past several centuries. SADA also exhibits more extended severe droughts and extreme pluvials since the mid-20th century. Extensive droughts are consistent with the observed 20th-century trend toward positive SAM anomalies concomitant with the weakening of midlatitude Westerlies, while low-level moisture transport intensified by global warming has favored extreme rainfall across the subtropics. The SADA thus provides a long-term context for observed hydroclimatic changes and for 21st-century Intergovernmental Panel on Climate Change (IPCC) projections that suggest SA will experience more frequent/severe droughts and rainfall events as a consequence of increasing greenhouse gas emissions

Dark Energy Survey Year 6 Results: Intra-Cluster Light from Redshift 0.2 to 0.5

Using the full six years of imaging data from the Dark Energy Survey, we study the surface brightness profiles of galaxy cluster central galaxies and intra-cluster light. We apply a ``stacking'' method to over four thousand galaxy clusters identified by the redMaPPer cluster finding algorithm in the redshift range of 0.2 to 0.5. This yields high signal-to-noise radial profile measurements of the central galaxy and intra-cluster light out to 1 Mpc from the cluster center. Using redMaPPer richness as a cluster mass indicator, we find that the intra-cluster light brightness has a strong mass dependence throughout the 0.2 to 0.5 redshift range, and the dependence grows stronger at a larger radius. In terms of redshift evolution, we find some evidence that the central galaxy, as well as the diffuse light within the transition region between the cluster central galaxy and intra-cluster light within 80 kpc from the center, may be growing over time. At larger radii, more than 80 kpc away from the cluster center, we do not find evidence of additional redshift evolution beyond the cluster mass dependence, which is consistent with the findings from the IllustrisTNG hydrodynamic simulation. We speculate that the major driver of intra-cluster light growth, especially at large radii, is associated with cluster mass growth. Finally, we find that the color of the cluster central galaxy and intra-cluster light displays a radial gradient that becomes bluer at a larger radius, which is consistent with a stellar stripping and disruption origin of intra-cluster light as suggested by simulation studies.Comment: Submitted to MNRA
