abstract = {Globally, groundwater is by far the largest store of liquid freshwater, making it a key component of a
secure water supply. However, over the past few decades the amount of usable groundwater available
around the world has rapidly decreased. This depletion is caused primarily by mismanagement (e.g.,
overpumping, contamination, and under-regulation), but also by reduced natural recharge due to climate
change and urbanization. Management of groundwater resources is particularly challenging for the
nearly 600 aquifers that are transboundary, meaning that they extend across international political borders. To understand how governance mechanisms can reduce water insecurity in transboundary groundwater contexts, we review key literature from what we view as the most relevant fields: groundwater
management, water security, international water law and international water governance. We then formulate a set of recommendations for improved groundwater governance that can address the specific
physical nature of groundwater systems, enhance water security, and apply to transboundary groundwater settings. We argue that groundwater governance in transboundary contexts requires processes that
(1) enhance context-specific and flexible international mechanisms; (2) address the perpetual need for
groundwater data and information; (3) prioritize the precautionary principle and pollution prevention,
in particular; (4) where appropriate, integrate governance of surface and subsurface water and land;
and (5) expand institutional capacity, especially of binational or multinational actors.},

There are different ways of modeling an aquifer: physical models, models based on analog and mathematical techniques. Usually, mathematical techniques involve complex operations difficult to understand for some people, such as differential or partial equations. In contrast, our method requires only a basic knowledge of geometry and trigonometry. Moreover, it is only necessary to know the static level of the aquifer at three different dates. Of course, the results may be limited compared to those that use advanced mathematical methods; however, our method provides a first approximation to determine the behavior of the aquifer through time. Overall, our results allowed us to follow the evolution of the aquifer in detail of various areas of increased extraction and in which removal has been increasing, but also of areas with a considerable recharge during the study period.},

abstract = {The urban-peri-urban interaction is frequently studied with a focus on the necessities of urban expansion, chronicling the concerns of land annexation, housing construction and infrastructure. However, in arid regions such as Mexicoʼs drought-prone northwest, the research on peri-urban issues must increasingly focus on the under-examined issue of the power geometries that are reshaping the contours of access to water in fastgrowing areas.
This paper examines geographies of power of the urban-rural interface in Sonora, Mexico. Focused in the political ecology framework, we compare the success of Hermosilloʼs water supply projects while analysing some cases of peri-urban water users and grouping them into three general types: negotiation, passiveness and resistance, with large powerful water users, referred to in this paper as 'counterpoint cases'.
We argue that urban water augmentation strategies reveal a distinct set of urban-peri-urban relations of unequal social power where peri-urban water resources are transferred to urban areas; reflecting, over the last three decades (1981-2010), the demands of powerful, politically connected urban populations and large irrigation districts. While during the same period, peri-urban small-scale communal farmers or ejidatarios lost access to their water as it was moved or used to supply the needs of Hermosilloʼs expansion.},

abstract = {Societal use of freshwater, ecosystems’ dependence on water, and hydroclimatic processes interact dynamically. Changes in any of these subsystems can cause unpredictable feedback, resulting in water insecurity for humans and ecosystems. By drawing on resilience theory, we extend current productive–destructive framings of water security to better address societal–ecosystem–hydroclimatic (SEH) interactions, dynamics, and uncertainties that drive insecurity but also offer response opportunities. Strengthening water security in this sense requires strategies that (1) conceptually and practically interlink SEH subsystems; (2) recognize extreme conditions and thresholds; and (3) plan for water security via structured exchanges between researchers and decision makers in ways that account for institutions and governance frameworks. Through scrutiny of case evidence from water-scarce regions in western North America and the Central Andes, we assert that ensuring water security requires adaptive management (interactive planning that accounts for uncertainties, initiates responses, and iteratively assesses outcomes). Researchers and stakeholders from these regions are pursuing a multiyear series of workshops that promote science-based decision making while factoring in the political implications of water planning. This study briefly reviews an emerging water security initiative for the arid Americas that aims to enhance understanding of adaptive approaches to strengthen water security. Finally, by synthesizing efforts in the arid Americas, we offer insights for other water-insecure regions.},

abstract = {Water demand at a basin level is influenced by many factors such meteorological variables, soil moisture, vegetation type and irrigation system. Among them, climate is the major driver, because weather conditions determine energy balances and vapor pressure deficits that affect the magnitudes of vapor flux from surface to atmosphere.
Monitoring evaporation is a great challenge since specific and costly equipments are required. As an alternative, agronomists and engineers use semi-empirical equations such as the Penman–Monteith formula to estimate potential evapotranspiration based on surface weather observations. Unfortunately weather stations are scarce and do not always have the instrumentation to measure relevant variables for its calculation.
In this work, we evaluate the use of numerical weather forecasts, obtained from MM5 model, as proxy for surface meteorological data with the specific objective of using them to estimate reference evapotranspiration (ETo) in the Maipo river basin. We compared three procedures to obtain ETo: (a) Raw MM5 estimates of latent heat flux; (b) calculation of ETo from Penman–Monteith equation, using raw MM5 outputs of weather variables; and (c) calculation of ETo from Penman–Monteith using MOS-corrected MM5 weather data. We used class A pan evaporation data and estimates of ETo using observed daily surface data to evaluate the precision of each method.
We found that the estimation of ETo based on MOS-corrected weather variables is usually the most effective method to estimate reference evapotranspiration. Since MM5 outputs in this region are available at 25 km grids, the number of monitoring sites can be increased substantially, improving the ability to capture spatial variability of water demands in the basin.},

abstract = {There is increasing interest in meteorological information and its application to strategic planning at the farm as well as regional level. Although we have recently seen signifi cant improvements to strengthen and enlarge networks of weather observations, their density is still insuffi cient to cover large extents at the desired spatial and temporal resolution. Climate scientists have developed and used mesoscale models to understand and predict future atmospheric conditions. These models represent a major contribution to objective weather forecasts throughout numerical simulations. They use global circulation outputs as boundary conditions and can be run in a nested manner so as to increase their spatial resolution. Because of this, we can obtain information about weather variables in grid cells spaced 15 km apart covering important areas and providing information in places where analog or automatic stations are not available. The objective of this work is to evaluate the use of raw data from the MM5 mesoscale model as well as MOS-corrected information (a statistical post-processing of MM5 outputs) as a proxy for surface meteorological data. Temperature, wind speed, relative humidity, and daily solar radiation forecasts were evaluated for eleven stations in the Maipo river basin. In all cases, the MOS forecast produced better results than the raw MM5 data. Determination coeffi cients reached values near 0.9, and the RMSE was usually smaller for MOS-corrected data. The small variability of the MOS parameters allows their use as regional values to estimate meteorological data for the whole region, particularly at a weekly time step.


En la actualidad existe un interés creciente por contar con información meteorológica que permita la gestión de la producción agrícola y el manejo de recursos naturales tanto a nivel de predio como a escala regional. A pesar que se han hecho esfuerzos considerables por fortalecer y expandir las redes de monitoreo meteorológico, todavía su densidad es insuficiente para proveer de información regional con el nivel de frecuencia y representatividad espacial deseado. Climatólogos y meteorólogos han desarrollado y empleado los modelos de simulación de meso-escala con el fin de mejorar la comprensión de los fenómenos meteorológicos y predecir el comportamiento de la atmósfera. Dichos modelos son alimentados por los resultados de modelos de mayor envergadura (Modelos de Circulación Global) quienes entregan las condiciones de inicio para que los modelos de mesoescala aumenten la resolución espacial mediante un sistema de ejecución anidado. Como resultado se logra obtener información climática en celdas que están espaciadas por 15 km. Esto es promisorio ya que tal densidad espacial tiene la capacidad de generar información en lugares donde no existen sistemas de monitoreo activos. El objetivo de este trabajo fue evaluar el uso de los resultados del modelos de meso escala MM5 a través de cuantificar la capacidad de reproducir condiciones meteorológicas observadas, tanto los resultados directos del modelo MM5 como también valores corregidos en base a un procesamiento estadístico conocido como MOS. Se seleccionaron 11 estaciones meteorológicas pertenecientes a la cuenca del Maipo y se evaluaron variables como temperatura, velocidad del viento, humedad relativa y radiación solar. Los resultados muestran que los procesamientos estadísticos posteriores mejoran notablemente las estimaciones iniciales llegando a mostrar coeficientes de determinación de hasta 0,9 (p = 0,01). Además se observa que los parámetros de las ecuaciones de regresión son similares entre estaciones, lo que abre la posibilidad de usar valores únicos de ellos para generar estimaciones regionales de variables meteorológicas y agroclimáticas particularmente a escalas de tiempo semanal.},

abstract = {Agriculture represents the main source of livelihood for small scale farmers, and a significant fraction of the gross domestic product in the case of intensive commercial agriculture. Because crop performance at the end of a growing season is strongly linked to the observed meteorological conditions, agricultural systems have been one of the main subjects of analysis to understand the impacts of both climatic variability and climatic change. As climate scientists make progress understanding the key elements of the atmosphere and provide with better projections of climate change scenarios, more effort is devoted to impact assessment and the evaluation of adaptation strategies to reduce vulnerability of crops and farmers. The objective of this work was to document the impacts of climate change on maize and wheat yields in Chile as well as to describe the dynamics of adaptation (i.e. changes in management decisions over time) that will take place, considering that farmers can “learn” from previous crop yield outcomes. Yield outcomes were obtained using a crop simulation model run under climate change scenarios based on HadCM3 projections. A simple decision model for a risk neutral farmer was used to investigate changes in optimum management decisions over time. Maize showed yield reductions in the order of 5% to 10%. Under irrigation, the best alternative for adaptation corresponded to adjustments in sowing dates. In the case of winter wheat significant yield reductions were observed for the no adaptation case. Because this crop showed positive responses to the increase of carbon dioxide, adaptation strategies were very effective counterbalancing the impacts of a warmer and drier environment. Dynamic adaptation was referred here to the introduction of small adjustments in management based on previous observed changes in productivity. This type of adaptation strategy outperformed prescriptive decisions based on historical or projected climate change scenarios, since it was sufficiently flexible to maintain near optimum economic performance over time, as climate varied from baseline to projected future conditions.},
