This slide show supports the 2nd webinar dedicated to learning about transboundary water negotiations. In the previous webinar (Sept 2021), the 1st round of negotiations ended with informal agreements on how to take the next steps. In the 2nd Round (to be conducted in the webinar (on the 29th Oct), the Parties will meet for the second time to continue with their negotiations. 5 years on, the demand and needs have increased and the urgency for reaching more formal agreemment is more urgent. Watch the seminar for the negotiations. This ppt illustrates the previous conditions and the new conditions, 5 years on.
1. • This ‘game’ based simulation of 2nd
Round of negotiations over a
transboundary river-aquifer is a
‘learning tool’ to better understand
the issues that arise when such
negotiations are carried out by
interested Sharing Countries.
• The negotiations are conducted by
two-person teams, one representing
“HillI’stan’ and the “Valli’stan”.
• They will conduct the 2nd Round of
negotiations on how to work
towards an Agreement to cooperate
over their shared resources

2. Summary of the 1st Round of negotiations
In 2005, the Parties voluntarily came to the negotiating table. With a
neutral facilitator, they put forward their positions on their water
needs from the transboundary system - an inter connected river-
aquifer.
They stated their preference for the way ahead - one Party proposed
an MoU, the other Party preferred a more formal treaty form of
agreement.
Both Parties stated that basic data and information about the river-
aquifer needed to be updated, before further steps could be taken.
However no formal document was signed or agreed, though they
agreed to meet again.
3. Transboundary issues – 2nd Round
The 2nd Round of negotiations is taking place 5 years after the last one.
• Hilli’stand - increasing water shortages – many private wells in the
wealthier districts – the permit applications is seriously lagging behind;
relevant Ministry lacks staff & resources. Suggestion that farmers reduce
well pumping, met with a serious threat of community rebellion; political
representatives promised to resist control pumping. As main food supply
area, difficult to reduce water use.
• In Valli’stan, demand for increased cotton irrigation meant more river
water diverted; some well drilling has started. Private sector financing is
creating political difficulties; Ministry facing with criticism.
• Modelling and data analysis has been somewhat updated – through a
University post graduate study, with limited new data, but by re processing
the past information.

A new post graduate study has re confirmed
the overall concepts of the hydrology & the
hydrogeology, they remain valid. The data from
the new well (drilled in the territory of
Valli’stan) has helped to better calibrate the
trends in water levels. The river flows data has
also been re confirmed using some remotely
accessed data – at present (2010) there is no
signal in these river flows records of climate
change.

In 2010, the 50 MCM/y demand has become more critical –
private wells have been drilled in the wealthier areas; in the
agriculture production region, well production continues and is
subject to intense political pressure not to reduce abstractions for
essential national food supply.
The IFI loan financing requires transboundary issues to be suitably
addressed.

Data from new

Some of the demand of the 35 MCM/y has been taken by new river
diversions, carried out via the Ministry due to political pressure. Some
private wells have also been drilled – but the permit applications are
lagging behind.
Internal financial interests have made it increasingly important to
address the reliability of water in the transboundary rivers. A
regulating dam on the river would make water resources more
reliable – but the best site is in the territory of Hilli’stan.
