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?

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?
