  3. 3. WP 2-Approach 1. Synthesis studies 2. 2 Time series meteorological and h d l i l d Ti i l i l d hydrological data collection f ll i from secondary sources/relevant ministries 3. Identification of information/data gaps and filling 4. 4 Quick understanding of hydrology and water balance a simple balance, spreadsheet water account applied with help of Mac Kirby 5. Detailed hydrological analysis – Assessment of the spatial variability in land use classification, precipitation and actual evaportranspiration using surface energy i it ti d t l t i ti i f balance model – Time series analysis of stream flow mainly using Flow Duration Curves (FDC) approach – Detailed b t h D t il d sub-catchment l t level water b l l t balance analysis using HBV and l i i d SWAT models
  4. 4. Spatial distribution of precipitation and actual evapotranspiration (2002-3) (2002 3) Rainfall distribution in the Basin Actual evapotranspiration in the (2002-3) (2002 3) Basin (2002-3)
  5. 5. Percentage distribution of ETa from different land use classes (year 2002-03, summary of SEBS results) Irrigated crops 11% Water Range Lands 7% 27% Other land classes 27% Bare Lands/Urban areas Bare Rain fed crops 27% Lands/urban 29% areas 3% Grass land 7% Orchards Forest 2% 21% Irrigated crops 39% (a) Upper Karkheh (b) Lower Karkheh
  6. 6. 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 i bilit f f t il bilit in t development and l t d allocation strategies, particularly for low flow years when meeting the competing water demands becomes more difficult.

  15. 15. WP 1 Findings 1. Poverty in Iran and the Karkheh has dropped over y pp the last 20 years, particularly in rural areas. 2. The Karkheh basin is less poor than is Iran as a whole. 3. Rural areas of the Karkheh are less poor than urban, when adjusted for differing costs of living 4. 4 Farmers are in the top half of the rural income F i th t h lf f th li bracket in the Karkheh. 5. The poorest rural area of the Karkheh is the lower reach-based on 6 sub-basin breakdown

  18. 18. 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.
  19. 19. 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
  20. 20. 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
  21. 21. Work Package 5 Water, Water Poverty and Productivity Linkages (Analysis of Interventions)
  22. 22. PODIUMSim: 2025 Horizon (Food & Water Demand and Supply) Three scenarios are developed: 1- Business as Usual Scenario Focus on wheat 2- Sustainable Management Scenario Focus on the environment 3- “Best Case” Scenario Focus on tradeoffs and social optimums Productivity/Poverty in all
  23. 23. WP 5 Findings • No question that increase in water use has allowed expansion of area and increase in y yields • But now no direct connection between p production and rural p povertyy • Probably greater connection between p production and urban p poverty and/or y national food security goals-which may be in opposition to WP maximization

  26. 26. 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?
  27. 27. 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 • MAKE THE PROJECT A TEAM EFFORT WITH EACH PACKAGE LEADER IS INVOLVED IN EVERY WORK PACKAGE
