URBAN GREEN AND RESILIENCE: AN EXPLORATION IN CÓRDOBA, FORTÍN AND AMATLÁN, VERACRUZ, MEXICO

Rafael Arturo Muñoz-Marquez Trujillo Juan Valente Hidalgo Contreras (2022, [Artículo, Artículo])

This article shows the amount and location of Urban Green (VU) in Amatlán, Córdoba and Fortín, Veracruz, Mexico, in the context of urban resilience to global warming. The objectives of this work are: 1) to know the situation of this resource in terms of its availability (endowment) by present area; 2) measure the distances that separate the green from the population; and 3) determine the population served through the Public Urban Green (VUP) and Urban Green in general (VU-NDVI), as well as contrast with the endowment and distance recommendations of the Secretariat of Agrarian, Territorial and Urban Development (SEDATU).. The working hypotheses are: a) Fortn, Córdoba and Amatlán have a VUP allocation below that recommended by the WHO, but have the possibility of higher allocations, considering the VU-NDVI; and b) Fortín, Córdoba and Amatlán have a VUP system at a maximum distance of 400 meters from each block, and contain VU-NDVI areas at smaller distances. With census and cartographic data, satellite image processing, use of Geographic Information Systems, field verification of the data, and statistical analysis, the amount of VUP and VU-NDVI, the green area endowments per inhabitant, and the distances that separate the two types of green in the population. The results showed, on the one hand, that the allocation of VUP per inhabitant is below the WHO recommendations, but not the VU-NDVI and, on the other hand, that the VUP exceeds the maximum distance recommended by SEDATU, but not thus the VU-NDVI. Finally, it is pointed out that, although the majority of the population is served with VUP in accordance with SEDATU (although with very varied surfaces), the VU-NDVI serves 100% of it. The results show the potential of the latter to increase the share of green in cities such as those analyzed.

Sistema de consulta de proyecciones regionalizadas de cambio climático para México

Martin Jose Montero-Martinez WALDO OJEDA BUSTAMANTE Julio Sergio Santana RICARDO PRIETO GONZALEZ René Lobato-Sánchez (2013, [Artículo])

Los modelos de circulación general acoplados permiten proyectar el clima futuro, pero no hay un modelo único, por lo que se recurre a ensambles de varios modelos. En este trabajo se utilizó un método estadístico para obtener un ensamble usando 23 modelos de circulación general mediante el algoritmo de fiabilidad de ensamble ponderado que considera dos criterios de fiabilidad: el desempeño del modelo para reproducir el clima actual y la convergencia de los cambios proyectados entre los modelos seleccionados. Se regionalizaron los datos de precipitación, y temperaturas máxima y mínima de superficie, con los escenarios SRES-A1B y SRES-A2 para el siglo XXI, y se incrementó su resolución espacial a una malla regular de 0.5 X 0.5° sobre México. Para facilitar el manejo de estos resultados se desarrolló un sistema, Sedepecc, que contiene las proyecciones generadas en una base de datos y las presenta a través de una interfaz amigable. El análisis de las anomalías proyectadas para el presente siglo en México indica un incremento general en temperatura y un decremento en precipitación. Los resultados indican que el cambio de la temperatura será mayor para el verano que para el invierno, acentuándose para las últimas tres décadas del presente siglo, donde los valores se proyectan por arriba de los 5°C para algunas regiones del centro del país. Como caso de aplicación del sistema, se generaron las proyecciones de cambio climático para el distrito de riego 075, localizado en el norte de Sinaloa, México.

Abduction according to Peirce: reflections from the south on the crisis of representation brought on by COVID-19

Paulina Aroch (2023, [Artículo, Artículo])

In this article, I reflect on the importance of abductive thinking for processes of material and conceptual reinvention in the context of the current public health crisis. Inseparable from the climate change engulfing the planet, this crisis provides the basis for a semiotic revolution. Therefore, I interrogate Peirce’s work without losing sight of my own time and place of interlocution. COVID-19 has brought with it a crisis of representation which, in contrast to that unleashed by the Holocaust and World War II, and to which the Frankfurt School responded, demands responses from the Global South. Beginning from Dussel’s call to defend life as a matter of ethical urgency in the face of its irresponsible objectification within colonial capitalist modernity –which arguably triggered the pandemic–, I trace a “nocturnal map” that registers the present meaning-making crisis, and allows for a reimagining and remaking of the world from elsewhere.

Debates contemporáneos sobre la eficacia de los derechos humanos en la globalización

ROBERTO MARTINEZ REGINO HECTOR ALEJANDRO RAMIREZ MEDINA (2023, [Libro])

En esta obra se abordan temáticas vinculadas a las demandas sociales que se han convertido en una fuente de interés y de preocupación para la academia y que, además, son el resultado del esfuerzo constante y persistente de posturas científicas que han permitido la apertura y el continuo desarrollo de líneas de investigación para la innovación del conocimiento susceptible de aplicación. Hoy en día, cualquier actividad humana a nivel individual o social, así como las actividades de la sociedad civil organizada o incluso de las instituciones del Estado están necesariamente vinculadas con los dos grandes ejes de la obra que tiene el lector en sus manos: los derechos humanos y la globalización.

En ese orden de ideas, no es de sorprendernos que las investigaciones académicas aquí presentadas sean visiones contemporáneas de cambios coyunturales y de propuestas de cambio a la estructura de las sociedades y que se interrogan sobre la vigencia del Contrato Social.

Climate change and the northern elephant seal (Mirounga angustirostris) population in Baja California, Mexico

M. Concepción García-Aguilar (2018, [Artículo])

The Earth0s climate is warming, especially in the mid- and high latitudes of the Northern Hemisphere. The northern elephant seal (Mirounga angustirostris) breeds and haul-outs on islands and the mainland of Baja California, Mexico, and California, U.S.A. At the beginning of the 21st century, numbers of elephant seals in California are increasing, but the status of Baja California populations is unknown, and some data suggest they may be decreasing. We hypothesize that the elephant seal population of Baja California is experiencing a decline because the animals are not migrating as far south due to warming sea and air temperatures. Here we assessed population trends of the Baja California population, and climate change in the region. The numbers of northern elephant seals in Baja California colonies have been decreasing since the 1990s, and both the surface waters off Baja California and the local air temperatures have warmed during the last three decades. We propose that declining population sizes may be attributable to decreased migration towards the southern portions of the range in response to the observed temperature increases. Further research is needed to confirm our hypothesis; however, if true, it would imply that elephant seal colonies of Baja California and California are not demographically isolated which would pose challenges to environmental and management policies between Mexico and the United States. © 2018 García-Aguilar et al.
