Local Food for Local Schools: The impacts of local procurement for a school feeding
program in Burkina Faso

May 23, 2012 seminar atUniversity of California at Riverside
• “Food Assistance” rather than “Food Aid”– Rapid expansion in cash, vouchers and,
especially, local and regional procurement (LRP) of food aid:• 11% of global food aid flows in 1999, then jumps
to 39% by 2008 and then 67% in 2010 following the 2008 Farm Bill LRP pilot and launch of USAID EFSP
– New (draft) int’l treaty: Food Aid Assistance Convention
• The promise:– More timely and rapid delivery– “Structured demand” can perhaps stimulate ag
dev’t– More “culturally appropriate” foods?
• The risks:– Market disruption from demand interventions– Food safety/quality
Background: The Policy Issues
• Burkina Faso: an ideal candidate for LRP?
• Frequent food aid recipient• Land-locked, so expensive/slow to reach• Agrarian, with surplus zones
• Evaluation opportunity– Natural experiment with partial replacement of
food aid from US under a Multi-Year Assistance Program (MYAP) with USDA-funded LP pilot for ongoing school feeding programs runs by the same agency (Catholic Relief Services).
– Gnagna and Namentenga Provinces• 364 schools serving 58,227 primary school students• Surplus cowpea production; net food buyers
Background: Burkina Faso and LRP
Methodology and Results: LEAP and MYAP
Background: Burkina Faso and LRP
• Procurement:– Vitamin-A Fortified Vegetable Oil
• Competitive Tender—Ouagadougou and Bobo Dioulasso• 72.1 MTs purchased
– Millet• Semi-competitive process through large grain cooperatives• Four unions, providing between 54 and 319 MTs each• 628.1 MTs purchased
– Cowpeas• Semi-competitive process through small farmers’
associations• 22 associations, providing between 2.8 and 21.4 MTs each• 143.5 MTs purchased

Background: Burkina Faso and LRP
Key Logistical Concerns:• Timeliness: does LRP really deliver faster?• Cost: is LRP really cheaper?• Quality: is LRP equally safe/reliable?
Macro-/Meso-level (Markets) Concerns:• Market Prices: does LRP disrupt local markets?
Micro-level (Recipients and Communities):
• Recipient Preferences: do they prefer local foods?
• Producer Impacts: do suppliers benefit?
Methodology and Results: Overview
Evidence from Burkina: Timeliness• Direct comparison (three observations each) versus multiple comparison
– Average difference MYAP-LEAP: 31.7 weeks– Average difference, U.S. Average – LEAP: 20 weeks***

• Questions and Challenges:– Are quality products available? Is adequate testing available?
Are standards (a) locally present, (b) enforceable?– Monitoring of stocks, especially with small-scale suppliers– Replacing spoiled foods

effects of food aid distribution• Are there demand side effects to worry about?

Evidence from Burkina: Recipients
Methodology and Results: Recipient Preferences
Exploit natural experiment to test recipient preferences based on food aid sourcing:
• Fielded among 120 schools each in MYAP/LEAP• Survey administered to the head school cook.
– Ask Likert scale questions (1=low/very unsatisfied to 5=high/very satisfied) about a range of consumption and preparation attributes of the food.
– Ask in general/absolute terms and relative to last year, when ALL schools were MYAP-supplied (diff-in-diff)
• Complemented by a school director survey covering school characteristics, such as quality of infrastructure, distance to markets, enrollment, attendance, and composition of students.

impacts on smallholder cowpea suppliers:
• Fielded among 160 members of LEAP-supplying farmer associations, with 150 control group members of MYAP zone farmer associations
• Standard farm survey questions were asked for the project year (2010-2011) and prior year
• Use difference in differences estimation for – farmers in LEAP associations (ITT) or – direct participants who sold to LEAP (ATET)

Results from the Randome Effects estimators are reported in the cases in which they were found to be unbiased, relative to the Fixed Effects models. If found biased, the Fixed Effects estimates are reported. These latter include: the ATET of Price received for cowpeas in project year, and both estimates for Individual transactions to sell cowpeas.

Methodology and Results: Producer Outcomes
• Transaction Costs / Profitability– 19% higher price received on average (relative to control
group) and 47% higher revenue – Association members who sold to LEAP also self-report
higher price, as well as improved profitability project year relative to prior year (on a Likert scale)
How, if agencies pay competitive prices (no market impacts)?

Answer: LEAP allowed farmers to delay sales and reap the benefits of seasonal market price increases

Quality Knowledge +++ +Storage --- +++Small Investments +++Traction Investments ++The "+" or "-" symbols indicate a positive or negative coefficient; the number of signs indicates the significance, +/-, ++/--, +++/--- for 10%, 5%, and 1%, respectively.
Summary: Trade-offs or Synergies?Benefits/Synergies:• Cost Savings all around
– 38% lower purchase cost for buyers (CRS)– 40% less distance traveled, and 20% higher price for
sellers• Agencies save on transport• Recipients eat what they know and like• Much faster delivery• Easier to enforce product quality standards• Local benefits “on both ends”
– Benefits from both the purchase and the distribution
“It is a smart child who, when at market, buys his ‘beignets’ from his own mom.”
- Mooré proverb
Trade-offs/risks:• Buying small works, but…
– Can this be scaled up significantly?– Response analysis capacity– Maintaining quality
• Commodities people prefer, but…– Preparation advantages?– Nutritional advantages?
Overall: local food procurement clearly a success by multiple metrics in Burkina Faso. Merits being made a permanent part of the food assistance toolkit.
