Abstract: | This paper reviews regional climate knowledge and vulnerability in the northern Mexico San Pedro River Basin, with a focus
on water quality, quantity, and management issues on the Mexican side of the border. A discussion based on the available literature
is supplemented by a survey assessing concerns about water and the quality and usability of climate and hydrologic information
available to water managers and communities. The surveys indicate that the central concern for urban residents is the lack
of reliable potable water due to frequent service breakdowns–with climate change and variability, specifically drought and
high temperatures, as contributing factors. Water managers desire appropriate meteorological and hydrologic information to
improve planning strategies, but access to this information remains limited. Considerable disagreement exists about who should
pay for previously free or low-cost water and wastewater treatment. Urban users have little incentive to conserve because
of the present flat, low rate and frustration with service. In rural areas, while a majority of ranchers recognize that variable
climate and water loss could increasingly jeopardize their lifestyle, they seldom use meteorological information in planning
or modify their water consumption. Climate vulnerability also includes potential for serious environmental health issues due
to the presence of heavy metals and organic contaminants in the San Pedro. |
