Amenazas y vulnerabilidades: las dos caras de los desastres en Celestún, Yucatán
Threats and vulnerabilities: two faces of disasters in Celestún, Yucatán
DENISE SOARES DANIEL MURILLO LICEA ROBERTO ROMERO PEREZ Gemma Millán (2014, [Artículo])
En este trabajo se reflexiona sobre la triada vulnerabilidad-desastres-desarrollo y se presenta un estudio de caso en el municipio de Celestún, Yucatán, sobre percepciones sociales acerca de la vulnerabilidad de la población frente a las amenazas de eventos meteorológicos extremos. Se pretende conocer las opiniones de la población respecto de su acceso a la capacitación sobre cómo enfrentar los huracanes, su capacidad para protegerse de dichas amenazas y su evaluación de la gestión de las autoridades locales en la materia.
Social and environmental constraints of the risks, responses to disasters, as well as the nature of the relationship between disaster and development have been the subject of increasing attention from researchers in the social sciences. That’s because the risks of disasters have become a growing threat by climate change. In this work we reflect over the triad vulnerability-disaster-development and present a case study in the municipality of Celestún, Yucatán, on social perceptions about the vulnerability against extreme weather events. We expected to know the views of the population regarding hurricanes, their access to the training and to evaluation of local authorities’ management.

Understanding the farmer's perspective has traditionally been critical to influencing the adoption and out-scaling of CA-based climate-resilient practices. The objective of this study was to investigate the biophysical, socio-economic, and technical constraints in the adoption of CA by farmers in the Western- and Eastern-IGP, i.e., Karnal, Haryana, and Samastipur, Bihar, respectively. A pre-tested structured questionnaire was administered to 50 households practicing CA in Western- and Eastern-IGP. Smallholder farmers (<2 ha of landholding) in Karnal are 10% and Samastipur 66%. About 46% and 8% of households test soil periodically in Karnal and Samastipur, respectively. Results of PCA suggest economic profitability and soil health as core components from the farmer's motivational perspective in Karnal and Samastipur, respectively. Promotion and scaling up of CA technologies should be targeted per site-specific requirements, emphasizing biophysical resource availability, socio-economic constraints, and future impacts of such technology.

Con la finalidad de impulsar el desarrollo de la región sureste de México, la actual administración del gobierno federal se ha propuesto la ampliación de la red nacional de gasoductos hacia esa zona del país, con el fin de suministrar energía a los megaproyectos de la región. No obstante, estas obras presentan actualmente retrasos, evidenciando la necesidad de metodologías de gestión que permitan solucionar este problema de raíz. Una de las metodologías más prometedoras en esta materia es la front-end loading (FEL), ampliamente aplicada en el sector extractivo y energético. El propósito del articulo estriba en evaluar la posibilidad de aplicar la metodología FEL a los proyectos de expansión del Sistema Nacional de Gasoductos en el sureste mexicano.
To boost the development of the southeast region of Mexico, the current federal government administration has proposed the expansion of the national gas pipeline network to this area of the country, to supply energy to the region's mega-projects. However, these projects are currently experiencing delays, demonstrating the need for management methodologies to solve this problem at its root. One of the most promising methodologies in this area is front-end loading (FEL), which has been widely applied in the extractive and energy sector. The aim of this paper is to evaluate the possibility of applying the FEL methodology to the expansion projects of the National Gas Pipeline System in the southeastern México.

Spatial phylogenetics in Hechtioideae (Bromeliaceae) reveals recent diversification and dispersal
La filogenética espacial de Hechtioideae (Bromeliaceae) revela diversificación y dispersión reciente

Background: Hechtioideae is a group of Bromeliaceae that is distributed in Megamexico III. In recent years, evolutionary relationships within this lineage have been studied; however, the biogeography of these plants have not yet been explored from a phylogenetic framework. The integration of geographic and phylogenetic information in the evolutionary study of organisms has facilitated the identification of patterns, as well as the exploration of new hypotheses that allow for the understanding the processes that have influenced the evolutionary history of lineages. Questions and/or Hypotheses: What is the biogeographic history of this lineage? How Hechtioideae has diversified over time? Results: The Neotropical region has the highest species richness of Hechtioideae and the Mexican Transition Zone is the area with the greatest phylogenetic diversity. This lineage presented its highest diversification rate during the late Miocene and Pleistocene (6.5-1 Ma). The ancestral area of the group corresponds to the Neotropical region and the Mexican Transition Zone. In addition, Hechtioideae spread across its current ranges through multiple dispersal events associated with climatic and geological events during the last 10 Ma. Conclusions: Hechtioideae is a group of recent origin whose evolutionary history has been strongly influenced by geological and climatic events over the past 10 Ma, such as the glacial and interglacial periods of the Pleistocene and the great tectonic and volcanic activity that led to the formation of the Trans-Mexican Volcanic Belt. © 2022 Sociedad Botanica de Mexico, A.C.
