Sustainable Water Management in Ciudad Juarez
No full textabstract: ABSTRACT Water resources in many parts of the world are subject to increasing stress because of (a) the growth in demand caused by population increase and economic development, (b) threats to supply caused by climate and land cover change, and (c) a heightened awareness of the importance of maintaining water supplies to other parts of the ecosystem. An additional factor is the quality of water management. The United States-Mexican border provides an example of poor water management combined with increasing demand for water resources that are both scarce and uncertain. This dissertation focuses on the problem of water management in the border city of Ciudad Juarez, Chihuahua. The city has attracted foreign investment during the last few decades, largely due to relatively low environmental and labor costs, and to a range of tax incentives and concessions. This has led to economic and population growth, but also to higher demand for public services such as water which leads to congestion and scarcity. In particular, as water resources have become scarce, the cost of water supply has increased. The dissertation analyzes the conditions that allow for the efficient use of water resources at sustainable levels of economic activity--i.e., employment and investment. In particular, it analyzes the water management strategies that lead to an efficient and sustainable use of water when the source of water is either an aquifer, or there is conjunctive use of ground and imported water. The first part of the dissertation constructs a model of the interactive effects of water supply, wage rates, inward migration of labor and inward investment of capital. It shows how growing water scarcity affects population growth through the impact it has on real wage rates, and how this erodes the comparative advantage of Ciudad Juarez--low wages--to the point where foreign investment stops. This reveals the very close connection between water management and the level of economic activity in Ciudad Juarez. The second part of the dissertation examines the effect of sustainable and efficient water management strategies on population and economic activity levels under two different settings. In the first Ciudad Juarez relies exclusively on ground water to meet demand--this reflects the current situation of Ciudad Juarez. In the second Ciudad Juarez is able both to import water and to draw on aquifers to meet demand. This situation is motivated by the fact that Ciudad Juarez is considering importing water from elsewhere to maintain its economic growth and mitigate the overdraft of the Bolson del Hueco aquifer. Both models were calibrated on data for Ciudad Juarez, and then used to run experiments with respect to different environmental and economic conditions, and different water management options. It is shown that for a given set of technological, institutional and environmental conditions, the way water is managed in a desert environment determines the long run equilibrium levels of employment, investment and output. It is also shown that the efficiency of water management is consistent with the sustainability of water use and economic activity. Importing water could allow the economy to operate at higher levels of activity than where it relies solely on local aquifers. However, at some scale, water availability will limit the level of economic activity, and the disposable income of the residents of Ciudad Juarez.Dissertation/ThesisPh.D. Sustainability 201
Thermoelectric properties of semiconducting metal-organic framework thin films and composites
No full textIn order to study the potential application and efficiency of semiconducting metal organic frameworks (MOFs) as materials for thermoelectric generators (TEG), 2- dimensional and 3- dimensional frameworks have been selected as initial targets. The 2-D framework employed in this investigation possess a honeycomb-like structure, containing Cu ions as nodes and coordinated to hexahydroxytriphenylene (HHTP) organic ligands. In addition, principle experimental studies on the incorporation of molecular iodine on thin films of this framework, Cu3(HHTP)2, via incipient wetness impregnation is demonstrated as an effective route to enhance its thermoelectric performance. Furthermore, the solvothermal synthesis and thermoelectric characterisation of a semiconducting 3-D MOF comprised of divalent FeII/III ions coordinated to tetrahydroxybenzoquinone (THBQ) organic moieties and core-shell like structures constituting Fe-THBQ coated Bi2Te3 nanowires are reported for the first time, expanding the scope of MOF heterostructures in energy conversion technologies. Thermoelectric measurements were performed on MOF pellets and thin films. The incorporation of MOFs as thin films provides a route for the design of new devices, although this is still an issue that is derived from the micro-sized crystals and their poor solubility in any solvent. Especially for those MOFs that exhibit electrical conductivity, the deposition of MOFs onto a given substrate is becoming important in order to assess them in practical applications such as chemical sensors, catalytic coatings and other electronic nanodevices. The fabrication of MOF thin films was conducted via electrochemical and dip coating techniques. The study of different structures of MOFs and their performance as TEGs is expected to expand and offer alternatives to non-toxic, scalable and high-efficiency novel TE material
Peri-Urban Farming: Occupying Voids in Ciudad Juarez
No full textThe main problématique of the site -Ciudad Juarez and the graduation studio was to investigate into the various issues contributing to the emerging phenomenon of abandoned housing in Mexico. In addition to poor urban planning, there is a fundamentally flawed system in the manner in which social housing is conceived, designed, produced, inhabited and devalued in Mexico. These factors create a cycle of decay and dysfunction of which abandoned housing becomes one of the many spatial consequences. The goal of the thesis project was to come up with a strategic proposal and interventions which can provide counter or alternative proposals to the current situation of decay and allow for a socio-economic platform to develop from within the community. The project investigates into how urban agriculture or in this case peri-urban (peripheral urban) agriculture and other related programs serve as a ‘bottom-up’ strategy to tackle the ‘top-down’ issues in Juarez. A matrix with a toolbox for production and an inventory of open space explores the possibility of creating continuous productive landscapes and new urban infills from voids and forms the first step towards orgainizing the city towards the creation of productive landscapes. This not only provides food for the community but also allows for transforming the current urban landscape in Riberas Del Bravo by transforming the ‘terrain vague’ – the abandoned houses, fallow land, unused urban spaces into productive, green spaces through urban farms, community gardens, community kitchens and greenhouses. Architectural expression of the primarily utilitarian buildings which develop during the phase-wise development of the strategy take into consideration local, easily available materials and passive climate concepts. The project also investigates into the role of various stakeholders and urban actors involved in the various stages of the institutionalization of urban agriculture in Ciudad Juarez to develop a multi-stakeholder platform for implementation of urban agriculture.Delft School of Design, DSDArchitectureArchitectur

Evaluation of the nutritional situation of the students of the "Benito Juarez" Elementary School according to the Body Mass Index. Jose Maria Morelos, Quintana Roo, Mexico
No full textIntroduction. The Body Mass Index, also called the Quetelet Index, is a measurement (kg/m²) used as an indicator of weight adequacy for a given height. The resulting value is interpreted as an indicator of different nutritional situations, both physiological (normal weight) and pathological (low weight, overweight and obesity). Objective. To evaluate the nutritional situation of the students of the "Benito Juarez" Elementary School in the Maya municipality of Jose Maria Morelos, Quintana Roo, Mexico, during the period from June 3, 2019, to July 12, 2020. Material and methods. Cross–sectional descriptive observational epidemiological study without directionality and with prospective temporality. One hundred and twenty–eight students from "Benito Juarez" Elementary School were evaluated. As a hypothesis test or statistical significance test, the Mantel–Haenszel Chi–Square statistic (x²M–H) was used. Likewise, the Epi Info software for Windows, version 7.1.4.0, was used to obtain the values of both the x²M–H statistic and the probability (p). Results. Fifty–four (42.19%), 70 (54.69%), 3 (2.34%) and 1 (0.78%) students presented low weight, normal weight, overweight and obesity, respectively. Conclusion. It is concluded that the students of the "Benito Juarez" Elementary School present health problems with respect to their nutritional situation, since 45.31% (58/128) have a pathological nutritional situation (low weight, overweight and obesity).
