Environmental disasters, ranging from catastrophic floods to extreme temperatures, have caused more than 30,000 deaths per year and US$ 250–300 billion a in economic losses, globally, between 1995 2015 (1). Improved infrastructure planning for events is essential urban areas, where an increasingly greater fraction of the world’s inhabitants reside. In response, international governmental private initiatives placed goal resilience at center stage planning. [For example, The 100 Resilient...

Abstract Background Bacteria used as indicators for pathogenic microorganisms in water are not considered adequate enteric virus indicators. Surface from a tropical high-altitude system located Mexico City that receives rainwater, treated and non-treated wastewater irrigation, groundwater drinking, was studied. Methods The presence of enterovirus, rotavirus, astrovirus, coliphage, coliform bacteria, enterococci determined during annual cycles 2001 2002. Enteric viruses concentrated samples...
Enterococci are part of the normal intestinal flora in a large number mammals, and these microbes currently used as indicators fecal contamination water food for human consumption. These organisms considered one primary causes nosocomial environmental infections due to their ability survive environment intrinsic resistance antimicrobials. The aims this study were determine biochemical patterns antimicrobial susceptibilities Enterococcus faecalis E. faecium isolates from clinical samples...
BackgroundRecycled treated or untreated wastewater represents an important health challenge in developing countries due to potential water related microbiological exposure. Our aim was assess quality and implications a Mexico City periurban agricultural area.Methodology/Principal FindingsA longitudinal study the Xochimilco wetland area conducted, 42 sites were randomly selected from 211, including irrigation canals effluents of treatment plants. Sample collection took place during rainy dry...
The world is facing a major pulse of ecological and social changes that may favor the risk zoonotic outbreaks. Such facilitation occur through modification host's community diversity structure, leading to an increase in pathogen reservoirs contact rate between these humans. Here, we examined whether anthropization alters relative abundance richness reservoir non-reservoir rodents three Socio-Ecological Systems. We hypothesized increases rodent while decreasing species. first developed...
ABSTRACT Fresh produce, such as lettuce and spinach, serves a route of food-borne illnesses. The U.S. FDA has approved the use ionizing irradiation up to 4 kGy pathogen kill step for fresh-cut spinach. focus this study was determine inactivation poliovirus rotavirus on spinach when exposed various doses high-energy electron beam (E-beam) calculate theoretical reduction in infection risks that can be achieved under different contamination scenarios E-beam dose applications.

SUMMARY Conservation policies have often been designed and implemented assuming that targeted communities are socially politically homogeneous. Payment for environmental services (PES) programmes overlooked intra-community differences, which affect the understanding of implementation requirements access to benefits, thus underestimating their effects on programme's legitimacy impacts. We explore how views local about socio-environmental performance dynamics Mexico's PES differ within forest...
Chinampería, a jeopardized precolonial agricultural practice, persists in the Xochimilco wetland, Mexico City. Agroecological chinampa production is recognized UNESCO World Heritage Site, and contributes to sustainability of both urban wetland city. The ‘chinampa-refuge’ model (CRM) transdisciplinary effort strengthen traditional agroecological practices ecological restoration. Through an inter/transdisciplinary research framework, we addressed model’s role this socio-ecosystem concerning...
Helicobacter pylori infection is associated with peptic ulcers and gastric cancer in humans. Transmission of H. still not certain some epidemiological data suggesting water as a possible transmission route. The objective this study was to detect 16S rRNA gene five systems the Mexico City area. Samples were taken between 1997 2000 from extraction wells (system 1), dams used sources, both pre- post-treatment (systems 2 3), treated wastewater 4) non-treated 5).

ABSTRACT In the Mexico City metropolitan area (MCMA), 70% of water for 18 million inhabitants is derived from Basin regional aquifer. To provide an overview quality groundwater, a longitudinal study was conducted, in which 30 sites were randomly selected 1,575 registered extraction wells. Samples taken before and after chlorine disinfection during both rainy dry seasons (2000-2001). Microbiological parameters (total coliforms, fecal streptococci, Vibrio spp.), presence Helicobacter pylori ,...
This article describes the poor environmental and living conditions in Mexico City due to its huge size. City's size is a challenge sustainability, outcome unknown. geographic basin surrounding it included about 18.5 million population 1995. The volcanic ranges include nine major zones. Urban growth followed four stages. Different cultures applied different solutions water supply problems. shifted from self-sufficiency reliance on 31% of supplies external watersheds. table declining canals...
The aim of this study was to evaluate the amount and quality water in Magdalena-Eslava river system propose alternatives for sustainable use. is last urban vicinity Mexico City that supplies surface area. Historical flow data were analyzed (1973–2010), along with physicochemical bacteriological attributes, documenting evolution these variables over course five years (2008–2012) both dry rainy seasons. analyses show regime has been significantly altered. significant differences between...
Abstract State-centered and hierarchical government strategies based on technocratic top-down approaches have proved inadequate to address multiple interacting cross-scale risks. In contrast, multilevel governance (MLG) provides a form of by networks that operate both in horizontal arena with neighboring local governments, civil society organizations, communities, vertical settings, higher-level governmental authorities international organizations. this paper, we examined the role experience...
