Appropriate land‐use, watershed‐management, and flood‐attenuation plans are critical in the cross‐border urban environment known collectively as Ambos Nogales. This paper summarizes methodologies for predicting the watershed response associated with land‐use change within a spatial and temporal context through the use of a hydrological model in a cross‐border setting. The KINEROS2 model is implemented via the Automated Geospatial Watershed Assessment 2.0 geographic information system interface to evaluate the watershed of Nogales, Arizona, and Nogales, Sonora, Mexico, to assess flood vulnerability by quantifying volumes of runoff and peak flow, based on alternative land‐use scenarios. Cross‐border geospatial data acquisition and input to models are described. Discussions about the KINEROS2 model results identify flood‐prone areas, simulate the impact of land‐use change, and evaluate the impact of potential flood‐control interventions in the Ambos Nogales watershed. Products from this research are being used in a comprehensive plan for sustainable development in Ambos Nogales.

This article examines the intersection between globalisation and allocation of open public space by testing the spatial equity hypothesis in Hermosillo, Mexico, a regional city impacted directly by global processes. Availability and accessibility of public parks were examined using a geographic information system and neighbourhoods were stratified into quintiles based on socioeconomic status. Overall, the analysis shows that the amount of public park space in Hermosillo is substandard and its distribution reveals a pattern of spatial inequity affecting primarily residents of poor neighbourhoods. We argue that as the economy of the city grows increasingly integrated into global circuits, the global-to-local connection materialises in an unequal competition between globalised spaces and local public space. This, in turn, leads to further relegation of neighbourhoods that are already on the margins of urban equity regarding access to public parks. This study extends prior research conducted in developed countries to a city in a developing nation and fills a vacuum of information that potentially can contribute to a more equitable development in Hermosillo.
