Basic seed – QDS (FAO – approved)
Foundation – certified – approved/quality declared

1–5 year – longer term Objectives
1. Seed Multiplication

Contract farmers in Mozambique, Tanzania, and Malawi – supervised by NDP/CRSP – evaluate seed quality
NABSLA (Malawi) - seed born pathogens an issue
Govt. Foundation Farm (Tanzania)
SUA
Bunda
ARC (Selian) Tanzania
Farms given seed of QDS
NGOs
SPS and Ministry of Agric. in Tanzania – both work with farmers

2. Dissemination
Malawi and Tanzania – provide seed with information for seed production to large and small-scale farmers
-Certified QPS
-Information about improved varieties
-Production seed and food – create demand for seed
-Storage – seed and food
-Seed sources – processing – marketing
-Farmers – small-scale and large
-NGOs
-Govt. extension offices
-Private traders
-Health centers
-Social services centers (units, etc.)

3. Marketing
Seed in Tanzania and Malawi – training seed producers (farmers, NGOs)
Advertising product – processing/packaging
When to sell
Market information where/when pricing and promotion are most relevant
Trader linkages
Promotional materials – brochures, protes, leaflets, advertisement

Food in Tanzania and Malawi – palatability information delivered to consumers
Promote nutrition and cookability for food security – open market
Cross border trade – consumer demand studies
Market chain studies

4. Storage – on-farm to improve traditional facilities – conduct a loss assessment study
Target traders and organizations
Assess pesticide use
Outlets – evaluate new technologies
Collaboration with R. Chirwa in Malawi
Tanzania can learn from work in Malawi

5. Impact Assessment
Conduct baseline survey by SUA and Bunda, and conduct a regional training
Need seed distribution and marketing in order to measure impact
Conduct impact surveys
Income produced from bean sales impacts consumption and nutrition
Distribution relationships – who benefits
Hectarage, yield-production statistics
Pricing (premium prices)

6. Trade
Identify and characterize external markets
Technoserve model
Determine export demand
Examine trade policies advocacy
