Session 5.1 Coffee and climate change: The importance of systems thinking

  1. 1. Coffee and climate change: the importance of systems thinking A systems approach for adapting to climate change in the East African highlands NaCORI A member of the CGIAR consortium www.iita.org
  2. 2. Why systems research? Goal: translate innovations into improved livelihoods 1. Systems framework as analysis – nested scales 2. Biophysical, socio-economic and institutional constraints 3. Agro-ecosystem or region as unit of analysis 4. Engaging with partners from the beginning Develop a theory of change A member of the CGIAR consortium www.iita.org
  3. 3. Suitability changes for Arabica and Robusta with climate change 21 IPCC models 19 bioclimatic variables Rains become more intense More erratic dry spells MAXENT APPROACH COFFEA CENAPHORA SUITABILITY IN UGANDA Outlook if coffee systems stay the way the are Arabica moves up the slope Robusta moves towards the equator NEED FOR ADAPTATION A member of the CGIAR consortium www.iita.org
  4. 4. Constraints for coffee production Climate change Institutional challenges Low soil fertility Pests and diseases Poor extension services Poor management practices Gender imbalances Post-harvest handling Poor access to markets Poor market information A member of the CGIAR consortium www.iita.org
  5. 5. Shade as an adaptation strategy Temperature under shade can be up to 5°C less than in full sun Shade protects flowers and berries during heavy storms Rwanda Burundi A member of the CGIAR consortium Uganda Tanzania www.iita.org
  6. 6. Impact of adaptation strategy on constraints In East Uganda, there is 50% less incidence of coffee leaf rust in coffee x banana systems In Central Uganda, there is more incidence of twig borer under shade A member of the CGIAR consortium www.iita.org
  7. 7. Perception of farmers about the adaptation strategy Benefits Constraints Shade is good for coffee Competition Fruits for eating Falling branches damaging coffee Nutrient cycling Hosting pests Fruits for selling Compacts soils Trees for fire wood Mulching Wind breakers Wood for timber Better quality Fodder Short-term benefits are important Need to manage competition between shade crop/tree and coffee A member of the CGIAR consortium www.iita.org
  8. 8. Managing competition in shaded coffee systems Soil critical values Foliar critical values Compositional nutrient diagnosis Micronutrient analysis is lacking Fertilizer recommendations based on most limiting nutrients A member of the CGIAR consortium www.iita.org
  9. 9. From crop to system: vulnerability of farmers to climate change in Rakai Results from 20 gender disagreggated focus group discussions Past - Access to communal grazing land - Access to wetlands Present - Communal grazing + wetlands are fenced off - Land-use changes: Eucalyptus trees are planted Vulnerability of smallholder farmer increases - When hit by a crises (ex. drought), farmer has no access to ‘buffer’ strategies - Farmer has to walk 4 km to access water because of wetland drainage With climate change incidence of crises will increase if no adaptation A member of the CGIAR consortium www.iita.org
  10. 10. Climate change adaptation at policy level Need to develop more resilient agricultural practices - Shaded coffee systems - Integrated soil fertility management - Water harvesting technologies - Crop diversification / shifts Need to study gaps and conflicts at policy level - climate change plan vs land policy vs wetland policy - National level vs. Local level - Inform and train implementors at local level Adaptation from plant to plot to household to policy to landscape A member of the CGIAR consortium www.iita.org
