Presentation by Johannes Ernstberger, MSc student in Agroecology (SLU) at the young researchers meeting on multifunctional landscapes, Gothenburg June 7-8, 2016.

1. Perceived multifunctionality of
agroforestry trees in smallholder
farming systems of Northern
Ethiopia
A participatory case study of the perceived functions and associated
personal values of trees in Northern Ethiopia’s agricultural landscape

Introduction
Background
• Multiple problems
-> Need a multifunctional
solution!

Agroforestry as a
multifunctional
solution?!
• But who plants or
manages those trees?
Soil fertility
(organic matter)
Clean air (carbon
sequestration)

5. Research Questions
• Which trees are prevalent?
• Which functions do these trees
fill?
• Why are these functions
important for households?

6. Methods
• Case study in Tigray
• 2 sites (sub-districts)
• Semi-structured interviews
• 55 household heads
• 5 informants

7. How to evaluate functions?
Methods
• Multiple functions -> Multiple values?
• Means-End Chain (MEC) framework
• Origins in Marketing Research
• Attributes
• Consequences (Functions)
• Personal values

11. “So what?”
• Multiple functions relate to multiple values
• Drawbacks MEC: What about basic needs?
• Farmers’ perspective: Which role does it play in the multifunctionality
of landscapes?
