What is agroforestry?
• Agroforestry is an integrated approach that seeks
to improve livelihoods and ecosystem services by
combining trees and shrubs with crops and/or
livestock.
• In a context of global change, agroforestry is an
approach to strengthen resilience of farmers and
communities in the face of stress and shocks,
mainly by building on diversification.
• The World Agroforestry Center has adopted a
landscape approach to its operations which
considers agroforestry as one of many components
of complex landscapes.
Climate Change in Mountain Areas
Climate change and climate variability require resilience,
especially in mountain areas, where the effects of
climate change are often more pronounced than in
adjacent lowland areas.
- Can combining trees with crops and/or animals be
regarded as a suitable adaptive strategy leading to
greater resilience in the face of climate change?
- Do mountains provide particular opportunities or
constraints for agroforestry as an adaptive strategy
to climate change?
Case studies from Central Nepal and SW
China
Baoshan: land use and climate change
Land Use
Complex farming systems with
agricultural and tree crops:
Agricultural crops:
rice, wheat, barley, sugar
cane, tree crops
Tree crops
Walnut, coffee, tea, pear,
sichuan pepper
Climate
Increasing precipitation
variability,
Severe drought in 2009-2010
Baoshan: impact on farming
Agricultural crop yields
declined more than tree crop
yields
Strong contrast in susceptibility
between tree species and between
age groups of tree species
Mustang: land use and climate
change
Land use
- Cereals and vegetables
- Temperate tree crops
Climate change
• Increasing temperatures
• Increasing but also
increasingly erratic rainfall
• Decreasing snowfall
Mustang: impact and response
• Decline of apple production
in lower Mustang
• Better conditions for
vegetables
• Shifting apple production
from lower to upper
Mustang
• Intercropping cereals and
vegetables with apple trees
in lower Mustang
Comparison
Baoshan
• Diversity of crops and trees
on farm-level has helped to
mitigate drought impacts
• Especially walnut trees have
survived with higher
productivity and lower
mortality
• Existing agroforestry
systems have proven
resilient
Mustang
• Due to the diversity of
available environments in a
complex mountain
landscape, climate change
has increased the diversity
of land use systems both on
the landscape and farm
level
• New agroforestry systems
have been adopted in
response to climate change
Conclusion
The use of trees in responding to climate change
and extreme weather events is not a panacea
but can be a viable approach within strategies of
agricultural and livelihood diversification to
improve community resilience.
The complexity of mountain environments can
be an asset for more flexibility in the face of
climate change.
