managing water resources, the International Water Management Institute is generating
reliable and systematic analysis ready water data products on water use, demand, water
availability and scarcity using water accounting plus (WA+) framework. The water accounting
plus (WA+) approach (Karimi et al., 2013) derives basin scale water availability and scarcity
indicators using earth observation data products and limited in situ observations. The WA+
framework is an open-source python programming-based model that uses a collection of
remote sensing data products and in situ data to quantify water accounting indicators such
as a) water yield, b) irrigation/rainfed water use, c) productive/unproductive water use, and
other water availability indicators at river basin scale. Scale Invariant Water accounting plus
(SIWA+) is a modified version of WA+ where the water accounting indicators can be generated
for any given boundary (catchment, or a country or a county).
The suite of water data generated by water accounting studies provides several new insights
into water availability and scarcity indicators at continental scale. The availability of open
source codes enables repeatable and rapid water accounting assessments without much
effort. IWMI’s WA dashboard is a web-based dashboard built using Tableau technology to
enhance stakeholder engagement and facilitate effective deliberation by summarizing and
communicating the key water accounts basin.

3.Key Elements of the WA Dashboard

There are five key elements in a WA dashboard:
i) Basin overview
ii) Water availability
iii) Water balance
iv) Spatial variation of WA indicators
v) WA indicators.
