The ICOW River Claims Data Set

The river claims data set follows the general guidelines on the ICOW home page.

A river claim is defined as explicit contention between two or more nation-states over the use or abuse of a specific river (or river system). Official government representatives (i.e., individuals who are authorized to make or state foreign policy positions for their governments) must make explicit statements contesting the usage of that river, typically involving concerns of water quality (e.g. pollution), water quantity (e.g. dams or diversion of water for irrigation), or navigation along the river.

Please note that the ICOW Project and its directors do not take or endorse official positions on any river claims. Our goal is to identify cases where nation-states have disagreed over specific issues in the modern era, as well as measuring what made those issues valuable to them and studying how they chose to manage or settle those issues. Inclusion/exclusion of specific cases, and coding of details related to those cases, follows strict guidelines presented in the project's codebooks (which are available below).

Measuring Claim Salience

The salience of river claims is measured by a 0-12 index, which includes up to six points each for the claim's challenger and target states (one point each for six indicators of salience). For more details see the Hensel, Mitchell, Sowers, and Thyne JCR article listed below in the data set references section of this page. Note that each indicator is coded separately for each claimant, as many rivers have different uses in different riparian states:

Current Status

We have finished data collection for the Western Hemisphere, Northern and Western Europe, and the Middle East for the years 1900-2001. Data collection for the rest of the world is currently underway, beginning with Eastern Europe (which will be released by the end of spring 2014 with version 1.2 of the ICOW data), followed by Asia/Oceania and Africa (both coming by the end of 2014).

RegionStatusNumber of Claims
(and Dyadic Claims)
Western Hemisphere Data collection completed (1900-2001) 20 distinct rivers
(28 dyadic claims/361 dyad-years)
Europe Western Europe: Data collection completed (1900-2001)

Eastern Europe: Research currently underway
Western Europe: 5 distinct rivers
(7 dyadic claims/81 dyad-years)

Eastern Europe: around 17 claims
(research still underway)
Africa Research currently underway  
Middle East Data collection completed (1900-2001) 11 distinct rivers
(47 dyadic claims/321 dyad-years)
Asia and Oceania Research currently underway  

Descriptive Details

Version 1.1 of the ICOW River Claims data set includes claims over a total of 36 distinct rivers or river systems. Some of these rivers are claimed by multiple claimants at various points in time or are settled temporarily only to see renewed claims later (perhaps over different uses of the river), so these claims include 82 dyadic claims that together cover 763 dyad-years. These claims have been managed through 19 militarized interstate disputes and 190 peaceful settlement attempts (including bilateral negotiations, non-binding third party activities like mediation or good offices, and binding third party activities like arbitration and adjudication).

Data Set References

The first published article to use the ICOW River Claims data set was Hensel, Mitchell, and Sowers' 2006 PG article:

A more recent article described an updated version of the data set, as well as comparing the territorial, river, and maritime claims data sets:

Several other recent papers investigate river claims more specifically:

Data

The river claims data set is included in the main ICOW data download, along with the territorial claims and maritime claims data sets:

We are also producing several other data sets related to international rivers, which many scholars might find useful for their own studies of rivers (whether or not they use the ICOW river claims data):

Please note that this, like all ICOW data sets, uses the list of country codes in the COW interstate system. Please see that list for help in identifying which countries were involved in the events included in this data set, or for any questions about when each country was considered a sovereign, recognized state.
