2. U.S. Government Partners
Please include this slide in your presentation in the appropriate location. Notes: Feed the Future connects U.S. Government efforts targeted at global hunger and food security. Led by USAID, Feed the Future draws on the resources and expertise of the U.S. Departments of Agriculture, Commerce, State and Treasury; the Millennium Challenge Corporation; the United States African Development Foundation; the Peace Corps; the Overseas Private Investment Corporation; the Office of the United States Trade Representative; and the U.S. Geological Survey.

3. Introduction
ILSSI is a cooperative research project aiming at improving food production, nutrition, accelerate economic growth within a sustainable environmental framework in Ethiopia, Ghana and Tanzania
Extensive engagement and consultation with national research and implementing agencies to identify type of interventions to be implemented
Field interventions used to:
-Explore technologies (technical/institutional) that have potential for outscaling
-Build national capacity
-Provide primary data for both empirical evidence base and input to models (IDSS)

4. Introduction (2)
Main objectives embedded in a multi-disciplinary framework:
Increasing small scale irrigation through interventions (single or bundled?)
Improving water use efficiency for households who already are practicing irrigation
Research project for development:
Research component => Innovative ideas/solutions
Development component => capacity building and engagement

a technical, socio-economic and gender perspective embedded in an sustainable environmental framework to understand adoption/disadoption

6. objectives ILSSI GW/SW related interventions for all 3 countries:
Irrigation technologies for high value crops (including fodder)
Improving water management for high value crops
Ways to increase infiltration/shallow groundwater (Ethiopia)
Evaluate the technologies from a socio- economic, agronomic, technical and environmental point of view (multi-disciplinary) at household level

7. objectives ILSSI (2)
Sustainability from field to watershed scale (monitoring => modeling IDSS)
IDSS= Integrated Decision Support System
Sustainability at
watershed scale
SWAT
Agronomic-environmental assessment at field level
APEX
Socio-economic & nutrition impact at farm level
FARMSIM

20. Experiments under ILSSI
Paul Reuben, Sokoine University of Agriculture
Experiments under ILSSI
Mkindo village
The block has about 50 farmers
All farmers will be involved in SRI to simplify water management
3 days wetting and:
T1 = 3 days drying
T2 = 5 days drying
T3 = 7 days drying
R/Mbuyuni : SRI with local varieties

21. WP 2: BUILDING CAPACITY TO OUTSCALE AND OPTIMISE RICE YIELD, WATER USE EFFICIENCY AND GROUNDWATER LEVEL IN SRI
One rice scheme per village in both Mkindo and Rudewa-Mbuyuni villages
Sokoine University: effect of various AWD strategies on rice yields
Gender disaggregated data on adoption of SRI within the scheme
What we would like to include:
Link to NAFAKA project and the AWD tube
AWD effect on rice yield at landscape scale: influence of lateral flows – linkage to GW levels and river return flows (modelling)
Up and outscaling of SRI water management within the scheme (linkage to AWD –scheduling tube outscaling)

23. WP1: ASSESSING FEASIBILITY OF SMALL MOTORIZED PUMPS FOR DRY SEASON IRRIGATION OF VEGETABLES AND IMPROVING IRRIGATION WATER PRODUCTIVITY
Mkindo and Rudewa-Mbuyuni villages: 2 motor pumps per village; each pump used by 8 target farmers.
In Rudewa-Mbuyuni village, an additional motor pump will be given to a group of eight youths
Water management: farmers practice against soil moisture based scheduling
Recording of irrigation quantity, timing, soil moisture, agronomic performance
Gender disaggregated data on activities related to the irrigation season & income, input and other costs
