Guess who said this:
“Some people say ‘Give the customers what they want.’ But that’s not my approach. Our job is to figure out what they’re going to want before they do. “Henry Ford once said ‘If I’d asked customers what they wanted they would have said ‘A faster horse.’

“People don’t know what they want until you show it to them.
“That’s why I never rely on market research. Our task is to read things thatn are not yet on the page.”

1. Farmer-Managed Natural Regeneration (FMNR) on cropland
2. Conservation agriculture with trees (CAWT)
3. Conventional food crop production interplanted with trees

What do we need to do to fully mobilize for the upcoming global revolution in
agroforestry upscaling?• Urgent need to map agroforestry across the
world at global, regional, and national scales
• Create a Global Agroforestry Assessment based on national assessments
• Develop a global plan to upscale agroforestry
• Staff up in linking agroforestry science to development

Channels for Reducing Vulnerability
1. Buffer crop production from drought stress
-- Sustain higher and more stable yields by more favorable microclimate
-- Conserve and enhance soil organic matter, infiltration and water holding capacity
2. Tree crops generally less severely affected by drought, heat, excess water
3. Greater diversity of income sources

Zero Net Land Degradation
Classify all land into three categories:
– Degrading– Regenerating– Stable
Monitor land degradation and regeneration in terms of biomass production.
Calculate the ratio: Regenerating/DegradingThe target is a ratio exceeding 1.0

What is Evergreen Agriculture?
A form of more intensive farming that integrates trees into crop and livestock production systems.
Evergreen farming systems are ‘double- story’ systems that feature both perennial and annual species (food crops and trees), maintaining a green cover on the land throughout the year.
