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

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
![Page 7: Systems research for climate smart agriculture an example of coffee in East-Africa by Laurence Jassogne et al](https://reader033.vdocument.in/reader033/viewer/2022042817/55a6e0761a28ab8c498b45dc/html5/thumbnails/7.jpg)
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 concentration
§ High shade tree density
§ Unfavourable soil pH
§ Soil Mg concentration
§ Elevation
§ Lack of mulching
§ Soil K deficiency
§ Lack of mulching
§ Low coffee plant density
§ Coffee twig borer
§ Old coffee trees

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

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
![Page 11: Systems research for climate smart agriculture an example of coffee in East-Africa by Laurence Jassogne et al](https://reader033.vdocument.in/reader033/viewer/2022042817/55a6e0761a28ab8c498b45dc/html5/thumbnails/11.jpg)
Climate change adaptation at policy and institutional 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? - Scaling?
Adoption: - Quality of inputs

• 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 adapted to farmer types • Constraints at landscape level might prevent adoption of CSA practices • Constraints at policy level might prevent adoption of CSA practices
