• Objectives and rationale• Steps in the project, timeline• Site selection, sample size• Project organization, teams, roles• Training: Tanzania + Malawi• First results
Objectives
• To find options for sustainable intensification and targeted innovations at farm-level
– Diagnose current whole-farm performance (RO1)– Explore trade-offs and synergies among ‘services’,
or objectives, identifying farm performance gaps– Interactive re-design of farming systems, to close
gaps– Inclusive project and stakeholder approach
Rationale (1)
• Based on household surveys, characterizations and previous engagements with farmers …
• … model-supported diagnosis and exploration of whole-farm options for sustainable intensification …
• … informing interactive adaptation and learning cycles conducted with farmers and other stakeholders.
Rationale (2)
• A farm-level approach allows to embed proposed and tested innovations
• Exploration, presentation and discussion of sets of options is needed to:– Analyze trade-offs and synergies (among
objectives, etc.)– Support adoption processes by providing choices– Avoid lock-in onto undesirable development paths
(= provide pathways out of poverty)

Site selection, sample size
• Tanzania, Malawi– Next growing season: Nov. 2013– Results by: Sep. 2013
• Ghana, Mali– Next growing season: Apr./May 2014– Results by: Dec. 2013
• Samples (dependent on capacity)– Rapid characterization 50-100– Detailed diagnosis 10-50
Milestones, products per stage
• Rapid characterization functional typology• Detailed description diagnosis per farm• Exploration T-S and promising options,
discussions with farmers a.o.
• Re-design implementation and demo plan for farm
innovations

Teams and roles• National teams (NT’s)
– Local recruitment (Number? Capacities?)• Data collection, entry, checks• Process with farmers
• Scientific team (ST)– 2 PhD students, 1 per region– 1 post doc researcher
• Instruct and train NT’s• Data analysis typologies• Perform modeling (diagnosis and exploration)
• Scientific supervision (SP)– Wageningen team
• Support trainings and all activities of ST
Training sessions
• On-farm data collection (ST NT)• Characterization, description (SP ST)• Exploration and re-design (SP ST)
First results
• Training: April 2013• Tanzania
– 2 teams of 4 enumerators– Surveys: 96 in Babati and 80 in Kongwa + Kiketo
• Malawi– 1 team of 4 enumerators– Surveys: 40 in Dedza and 40 in Ntcheu
• Sampling: Y-frame

To do:• Check + clean 256 surveys • Collect secondary data• Build basic farms in FarmDESIGN• Model runs and analysis of results• Farm typologies (per country and region)• Plan detailed characterization (sample = 10%)• Inventory of ‘Innovation-Basket’• Cooperate: talk, meet, discuss, etc. (today)• Identify entry-points (later)• ….
