Understanding multifunctional landscapes and their change to inform intensification efforts
Hanna SinareMultifunctional landscapes for food security,
livelihoods and the environment7-8 June 2016
Outline• Entry point to these
landscapes• Approach to study
these landscapes• Changes in landscape
units and ecosystem services 1950-2013
• Implications for sustainable intensification
Entry point: Large scale studies show a greener Sahel
Herrmann et al. (2005)
Trends in residual NDVI, 1982-2003
What does it mean for people?

Change in social-ecological patches
• Increase of fields, decrease of shrubland and woodland– 3 villages: Fields covered 40 % in 1950’s, increased to
60-70 % 2010’s– 2 villages 30 % 1950’s, increase to 40 % and 60 %– 1 village almost 70 % Fields 1952, increse to almost 80
% in mid-1980’s

What does area mean for benefit?
Messages and questions for intensification efforts
• Multiple benefits from each patch – assess changes in all of them to understand livelihood effects of intensification
• Model effects – how can intensification change patches?
• How can intensification be sustainable and attract new generations of farmers?

Thank you!
Change in social-ecological patches over time
• 100 x 100 m squares with point 5 m radius in the middle– Social-ecological patch
• Systematic or random changes between social-ecological patches?
• Change in role of the landscape for livelihoods?
