Adaptation Challenges in Complex Rivers Around the World: The Guadiana and the Colorado Basins

CPO's Roger Pulwarty is the lead author of  "Adaptation challenges in complex rivers: The Guadiana and the Colorado Basins," which was published in the January 2015 issue of Water Resources Management. He collaborated with  co-author Rodrigo Maia of the Water Resources and Environment Division at the Faculdade de Engenharia de Universidade do Porto in Portugal.

The authors found that Integrated water resources management provides an often-recommended governance framework to manage water resources in a sustainable way. Still, the application of this framework on Transboundary Rivers comes with additional challenges, which are exacerbated due to climate changes and extremes (such as droughts). These changes affect the operation of water infrastructures and will, in turn, affect water management practices. Thus, the understanding and development of adaptation measures (across socio-economic, environmental and administrative systems) are critical, mainly on drought prone transboundary river basins.

The paper draws on research conducted to:

  1. Assess climatic risks in those watersheds,
  2. Describe the challenges in water resources management in the context of climate change, and
  3. Draw lessons for improving the use of research-based information

The authors selected two case studies, the Colorado River Basin (North America) and the Guadiana River (Iberian Peninsula), the latter of which in the context of the five river basins shared between Portugal and Spain.

Research and experience in these Basins show that several paradoxes in multistate water management and governance across borders militate against the accurate assessment of socio-economic impacts and the effective use of scientific information for meeting short-term needs in reducing longer-term vulnerabilities. Lessons drawn from both studies, but not always learned in practice, abound.

These lessons include an expanded use of incentives for improving collaboration, water-use efficiency, demand management and for the development of climate services to inform water-related management as new threats arise.

Recommendations are established for more effectively linking risk assessment approaches with resilience strategies that are applicable in practice and available to decision makers in a changing climate.

ABOUT OUR ORGANIZATION

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2011, the United States experienced a record high number (14) of climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 670 lives, caused more than 6,000 injuries, and cost $55 billion in damages. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
