2. Introduction
• Consensus that market access for smallholder farmers lead to increased
adoption of agricultural technologies, income and food security leading
to poverty alleviation.
• Smallholder challenges: Lack of information on prices and
technologies, high transaction costs, collective action, underdeveloped
market infrastructure, and credit constraints.
• Collective action:
 Important in reducing transaction costs, secure access to new
technologies, and improve farmers’ bargaining power.
 linkages across the market chain and connect producers,
processors, and buyers into networks that would be beneficial for
all actors.
• Understanding the factors that determine collective action and market
participation important

3. Output 4.2: Collective action models and alternative approaches linking farmers to
markets developed and pilot tested
• Activity 4.2.1: Identify and evaluate existing mechanisms that inform farmers
about dynamic market needs
• Sub-activity 4.2.1.1. Examine mechanisms that inform farmers about
dynamic market needs and factors that influence collective action in market
participation
 Objective: To identify existing mechanisms that inform farmers about
dynamic market needs and factors that influence collective action in the
maize and common beans markets.
 Location: Babati, Kongwa and Kiteto districts

5. • Activity 4.2.2: Conduct an analysis of the existing baseline survey data and
supplement them with qualitative surveys from target regions.
• Sub-activity 4.2.2.1. Assess the welfare effects of participating in maize,
groundnuts, and pigeon peas markets in Malawi, Tanzania and Zambia.
 Objective: To examine the determinants, extent and welfare effects of
market participation in maize, groundnuts, and pigeon peas markets in
Malawi, Tanzania and Zambia.
 Location: Malawi, Tanzania and Zambia.

7. Output 1: Economic analysis of selected Sustainable Intensification technologies
conducted.
• Activity 1: Conduct an analysis of the economic returns of soil and water
conservation technologies in central Tanzania.
• Sub-activity 1.1 Assess the effect of TR/RTR and Fanya-juu’ terracing on
maize productivity, household income and food security.
 Objective: To estimate the effect of TR/RTR and Fanya-juu’
terracing on maize productivity, net returns, household income and
food security.
 Location: Kongwa and Kiteto districts.

9. • Activity 2: Analyze the factors affecting the joint adoption of sustainable
intensification practices and impact on maize productivity.
• Sub-activity 2.1: Determine the effect of the joint adoption of improved
maize varieties and maize-legume intercropping on maize productivity and
crop incomes in Malawi.
 Objective: To examine the effect of the joint adoption of improved maize
varieties and maize-legume intercropping on maize productivity and net
incomes in Malawi.
 Location: Dedza, Mangochi and Ntcheu districts.

11. Moving forward as you prepare your workplans:
• Profitability analysis: Gross margin analysis is good for enterprise selection,
but we can go further:
 Cost-benefit analysis
 Marginal analysis (breakeven analysis): Breakeven yield and price
 Other indicators : Returns to labour and input use intensity
• Early adoption : Adoption constraints, dis-adoption and opportunities.
• Early impacts: Ex-post and ex-ante impacts.
 Ex-ante impacts with plot/field and household data.
