Water security and adaptive management in the Arid Americas

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.

Alberto Garrido, Helen Ingram and Robert SandfordAn ATM network topology management method for an ATM network using an NBMA Next Hop Resolution Protocol (NHRP) to obtain an ATM address from a network address in the ATM network, when a network management system (NMS) is directly connected to the ATM network, including the following steps: (1) reading a network address of an NHRP server that has been set in an NHRP client placed in the NMS; (2) recognizing a topology of a logical subnet served by the NHRP server within the ATM network by accessing the NHRP server with a network address derived from step (1) and obtaining information on a logical subnet served by the NHRP server, an ATM terminal and an ATM switch belonging to the logical subnet; and (3) the NMS reading information on another NHRP server within the ATM network from the NHRP server, obtains a network address of the other NHRP server, accesses the other NHRP server with an obtained network address and obtains information on other logical subnet served by the other NHRP server and an ATM terminal and an ATM switch belonging to the other logical subnet so that a topology of a logical subnet served by the other NHRP server is automatically recognized in the ATM network.

Shipping water across the US–Mexico border: international governance dimensions of desalination for export

ABSTRACT New public–private desalination projects along the Mexico–United States boundary have the potential to strengthen water security in this arid region. International bulk water commerce in this region is unprecedented and constrained by existing international agreements and regulations. This problem is examined from a multilevel governance perspective, focusing on two desalination projects with near-term export potential in Rosarito, Baja California, and Puerto Peñasco, Sonora. These projects add to the array of agencies and procedures in binational water management but will not displace the International Boundary and Water Commission, which is sure to have a role in managing such projects.
