Needs for climate change adaptation in coffee
Sustainable intensification and climate smart agriculture
CSA and SI are highly complementary
CSA
1) Increase productivity to support income, food security and development
2) Increasing adaptive capacity at multiple levels
3) Decrease GHG emissions and increase carbon sinks
SI
1) Increased crop production to sustain livelihoods
2) Low environmental impact
3) Future generations
Campbell et al., 2014
Perceptions of cliamte change
More drought, more storms
Yield is affected but also pests and diseases
Farmers do little and if they do something, they diversify
Most of the countries that responded find the country unprepared
Coffee systems will change in the future
Climate change adaptation per location
Planning for climate change adaptation in coffee different things in different locations
- Adapt your systems
- Adapt your crops – change your crops
Current suitability Future suitability
Impact of climate change on coffee
Climate change has an impact on coffee directly and an impact on pests and diseases
Is altitude (climate) the real factor?
There is a significant interaction
between production systems
Example of Coffee Berry Disease ( but also coffee stem borer and leaf rust)
What can we do? Importance of scales
Adaptation at plant and plot level
At plant level: drought/disease resistant varieties, pesticides, herbicides, fertilizers, GAP, etc.
At plot level: coffee x banana, integrated soil fertility management, coffee x shade, etc.
� Soil P deficiency
� Low coffee plant density
� Soil K deficiency
� Soil P concentrat ion
� High shade tree density
� Unfavourable soil pH
� Soil Mg concentrat ion
� Elevation
� Lack of mulching
� Soil K deficiency
� Lack of mulching
� Low coffee plant density
� Coffee twig borer
� Old coffee trees

Yield gap analysis for coffee in Uganda
What about adoption?
Need short-term benefits for the farmers
Do attitudes matter for technology adoption?
Pessimist
Negative attitude, does
not think farming is a
good investment. Prefers
investing in off-farm
activities.
Pragmatist
Positively coping,
farming is a good
investment but children
should not farm.
Trapped
Does not want to farm and
has low hope. But seems to
be trapped in farming.
Optimist
Proud to be a farmer,
farming is good invesmtent.
Wants children to farm.
Who can invest?
Not every investment costs the same money, we need to know which strategies are
needed where, but we also need to know their cost
Who decides? Looking inside the household
- Women ‘steel’ coffee from men
- Men ‘overspend’ household income
- Men turn to women’s crops, especially in times of crises
Joint decision making and planning
- Difference at farm level?
- Difference at coffee level?
At household and community level
Community in a landscape
Coffee and other crops
Wetland
Communal grazing land
Intensifying? Adapt to CC?
Eucalyptus
Need to develop more resilient
agricultural practices
- Shaded coffee systems
- Integrated soil fertility
management
- Water harvesting technologies
- Crop diversification / shifts
Climate change adaptation at policy level
Align wetland policy with climate change adaptation plan
In the case of Rakai
Other challenges
Planning:
- Develop climate change adaptation plan at national and regional level
- What is the vision for the future?
Adoption:
- Quality of inputs
Conclusions
Possible changes in land use and crops induced by climate change

• Training packages need to be planned by location
• Climate change adaptation also means developing other livelihood options than coffee
• Most of the research on climate change adaptation at plant and plot level
• There are different types of coffee farmers
• We need to have an investment scale with the technologies in training packages
• We need to know which farmers we are targeting
• Changes in behavior within households need interventions at community level
• Constraints at landscape level might prevent adoption of CSA practices
• Constraints at policy level might prevent adoption of CSA practices
• We need interventions at all levels of the system
Way forward
• Research needs to feed in more closely with existing training networks
• Need to adapt, feed into training packages that already exist
• Create platforms at international, national and regional scale to consolidate the adaptation
plans and trainings
• Research can be involved at each step of the process and use feed-back loops to improve
the process
• We cannot only work on what but also on how much it costs
• Example of cocoa in Ghana
Coffee systems: nested scales
