ICIWaRM participated in the International Symposium on Water Diplomacy, held on 16-17 November 2016 in Stockholm, Sweden. A professor from ICIWaRM’s partner institution Oregon State University gave one of the keynote addresses.

ICIWaRM’s primary communications mechanism is through its website, (which redirects to The site had to be migrated from in early 2018, due to the shutting down of the US government site-hosting system.

ICIWaRM’s partner, the University of Arizona, hosts the G-WADI website ( This had to be migrated within UA in 2017-2018 due to server and security issues.

Update on Centre Operations

ICIWaRM’s founding director, Mr. Robert Pietrowsky, retired in June 2018. Following a series of acting directors, Dr. William Logan was named director in April 2018. Other leadership changed in the period 2016-2018. Dr. Joe Manous replaced Mr. Pietrowsky as Director of the Institute for Water Resources—the host institute for ICIWaRM. Mr. James Dalton replaced Mr. Steve Stockton as the Director of Civil Works for the US Army Corps of Engineers. And Mr.

R.D. James assumed the role of Assistant Secretary of the Army (Civil Works), replacing Ms. Jo Ellen Darcy. The Assistant Secretary chairs ICIWaRM’s Advisory Board.

Evidence of the Centre’s Impacts

In addition to the numbers of participants trained at training courses and workshops that ICIWaRM has (co-)organized or participated in, some metrics of ICIWaRM’s success are:

  • The iRain website has had 305,000 visits from 189 countries.
  • Downloads of precipitation data from UC-Irvine’s Center for Hydrometeorology and Remote Sensing have more than doubled every year from 0.5 terabytes (~one trillion bytes) in 2013 to a projected ~20 terabytes in 2018. ICIWaRM began directly supporting CHRS around 2012.
  • The African Flood and Drought Monitor, in 2016-18 alone, has been applied to problems as diverse as human migration, human and ruminant epidemiology, drought resilience, and impacts of irrigation dams on growth rates.
  • The World Bank’s Water Global Practice has begun funding Princeton to develop high- resolution versions of the Flood and Drought Monitor to both the Lake Chad basin as well as the Salado River basin in Argentina. IHP and other UNESCO entities are also engaged directly in the former.
  • The US State Department has signed a three-year agreement to fund ICIWaRM for transboundary water cooperation work.

Future activities that will contribute directly to IHP and/or to WWAP

We anticipate continuing to work closely with the G-WADI Program, as Global Technical Secretariat, on existing initiatives described above, as well as on two more recent IHP initiatives. These are a) adapting the Latin American Drought Atlas based on regional frequency analysis to the African context, and b) support for G-WADI water harvesting activities, with leadership from the Regional Center for Water Harvesting, a category 2 center in Khartoum, Sudan.

With modest multi-year funding in place from the State Department, we anticipate continued efforts to assist in transboundary water management, and with a publication on Collaborative Risk-Informed Decision Analysis near completion, we believe that this will create a demand signal for assistance in adaptation to changing conditions for water resources management.

Activities in the framework of the SDGs

ICIWaRM plans to continue supporting IHP in their efforts to address the water-related SDGs, through our involvement in IHP-VIII theme 1 (Water-related disasters and hydrological change) and 3 (Addressing water scarcity and water quality).
