1. The Karkheh Basin Focal Project took a multi-disciplinary approach to understand water availability, productivity, poverty, and institutions in the basin.
2. Key findings included groundwater overdraft, high variability in evapotranspiration, the need to incorporate flow variability in planning, and substantial room for increasing water productivity.
3. Recommendations focused on improving rainfed and irrigated practices, targeting irrigation, exploring additional water sources, and shifting from low-value grain to higher-value crops and uses over the long term.

7. WP 2 Findings
• Scarcity and Competing Demands Meeting the competing water
demands is emerging as the key challenge in Karkheh mainly because of
increasing allocations for irrigation
• Groundwater Overdraft Rapidly increasing reliance on groundwater use
for agriculture, especially in upper Karkheh. Groundwater withdrawals have
already exceeded the safe limits in Gamasiab and Gharsu sub-basins and
sub basins
pose a threat to agricultural sustainability.
• High Variability in ET Remote sensing analysis showed high inter- and
intra-subcatchment level variability in evaportranspiration which is mainly
attributed to fragmented and diverse land uses in Karkheh-possible
g p
opportunities
• Flow Variability and Planning FDC analysis reveals that planning on the
basis of mean annual surface water availability could only provide a supply
security in the range of 35-50%. There is a need to incorporate the natural
variability of surface water availability i water resources d

20. WP 4- Approach
1. Examine the history of the basin-in terms of water use
as well as th policy environment i which th t use
ll the li i t in hi h that
changed.
2. Gain an understanding of the formal institutions
directly i
di tl involved in the water sector within th
l d i th t t ithi the
Karkheh.
3. Look at those institutions within Iran in general and
the Karkheh in particular which are directly related to
the alleviation of poverty.
4. Look at some of the broader policy issues within Iran
which are likely to influence both water use and
poverty within the Karkheh.
21. WP 4 Findings
1. Basin has gone through a series of phases
since 1900, the most recent of which has put
substantial emphasis on wheat production, not
water productivity. Questions of sustainability
2. “Standard” set of partially overlapping water
management institutions
3. Large set of poverty alleviation institutions
22. 4) Broader issues
• Fall of Shah, conflict with US/West and Iran-Iraq war
q
made food self-sufficiency a national priority
• Ongoing wars on two borders and nuclear conflict with
west given continued reason for policy
• Result is use of water for low productivity grains that
could be imported
• P i i and subsidy system th t b
Pricing d b id t that benefits mostly th
fit tl the
urban sector and encourages waste-Iran now one of
largest agricultural importers
• Implicit subsidy on fuel equal to 12% of GDP-targeted
redistribution of about ½ would eliminate poverty

28. High Priority Research
1. What makes basin results comparable or not?
– Agro-ecosystm
Agro ecosystm similarity?
– Economic similarity?
– Political similarity?
The answer may change for given basins over time.
2.
2 What are the national and global water impacts of food self-sufficiency
policies, such as those caused by food embargo threats?
– especially applicable to the arid and generally water scarce states of the Middle
East/North Africa.
– Not unreasonable to hypothesize that water productivity gains from policy change in this
arena could be as large or larger than those possible through technical intervention
intervention.
3. Is there a general framework to determine when and where (both within
and across countries/basins) water is a cost effective poverty alleviation
tool?
4.
4 How to better consider surface/groundwater interaction and implement
effective groundwater policy?
5. How best to capture livestock, fisheries, forestry and possibly other
agricultural systems? How to easily move from average to marginal water
productivity calculations for use in decision making?
29. Key suggestions for new BFPs
• Do quick assessments/reports on key issues
• Take
T k an historic perspective to understand h
hi i i d d how things got to the
hi h
current state
• Take a broad view of policy and its effects on agriculture and water
use
• Make sure any water productivity estimates are inclusive, e.g.
livestock-maintain difference between average and marginal
• Think simultaneously about water as a means for overall economic
growth,
growth reducer of poverty in general and reducer of poverty in the
general,
agricultural sector and the tradeoffs between the three
• Put another way, don’t force the water poverty issue but think about
water as a means for additional poverty alleviation
