  3. 3. Research Structure
  4. 4. Spatial Data and Analysis @ CIP:  Data Management / Sharing • Genebank data management • (Sweet) Potato Atlas: - Geography / Potential production zones • Contributions to Geonetwork: - Spatial data on (sweet) potato - Climate surfaces • DIVA-GIS…  Modeling and GIS • System Analysis (‘Tradeoff Analysis’) • Digital Soil Mapping • Environmental Vulnerability Assessment • Climate Change applications • Pest and Disease modeling  Remote Sensing • Disease detection • Cropping areas / crop statistics
  5. 5. Data Management / Sharing • Genebank data management: - Linkage of in-situ & ex-situ genebank management (potato parque Cuzco) - ‘Participatory’ GIS
  6. 6. Modeling and GIS • Ag. System Analysis (Tradeoffs production ~ env.): - Modeling scenarios of technology and policy interventions - Tradeoff Analysis framework: coupled bio-physical and econometric models - Spatially explicit (depending on research question)  Effects of market prices on soil nutrient depletion  Ex ante impact assessment of introducing improved varieties in CC context  Effects of adapting ICM practices on soil fertility/health  Land use change / intensification scenarios  Effects of water harvesting (e.g. terracing) on yields and poverty www.tradeoffs.nl
  7. 7. Modeling and GIS • Environmental Vulnerability Assessment: - Modeling scenarios of agricultural intensification  Land Degradation (e.g. landslides, water erosion)  Nutrient depletion  Pesticide leaching
  8. 8. Modeling and GIS • Potential soil erosion in Africa (ILRI): - Secondary data: climate, soils, topography, landcover, hydrology - (R)USLE + attempts on using physically based model (LAPSUS)
  9. 9. Modeling and GIS • Climate Change applications: - Drought mapping based on RS (time series of NDVI) Drought Probability Index Drought Probability Index ‘Normal’ El Niño Max NDVI Min NDVI Current NDVI PCC Drought Map
  10. 10. Modeling and GIS • Climate Change applications: - Ex ante assessment of adaptation technologies/policies (e.g. introduction of drought-, heat-, disease - tolerant or short duration varieties,…) - Collaboration with Max Planck Institute for Metereology on regional climate modeling - Wavelet tools for rainfall mapping (climate extremes) Vulnerability to Climate extremes: Wavelet tools for rainfall mapping (ppm) HUANCANE 50 40 m.m. 30 20 10 0 1-Jan-99 20-Jul-99 5-Feb-00 23-Aug-00 11-Mar-01 27-Sep-01 15-Apr-02 1-Nov-02 Días

  12. 12. Modeling and GIS • Pest and Disease modeling: - Risk mapping of Potato yellow vein virus
  13. 13. Remote Sensing • Disease Detection: - Low cost air-borne platforms for high resolution RS - Spectral signatures of disease symptoms - Early warning applications (e.g. potato yellow vein virus transmitted by whiteflies)
  14. 14. NDVI 0-0.1 0.1-0.2 0.2-0.3 0.3-0.4 0.4-0.5 0.5-0.6 Fresh yield (t/ha) <16 >24 60 60 50 50 Fresh yield (t/ha) Fresh yield (t/ha) 40 40 30 30 20 20 10 10 0 0 1 2 3 4 5 6 7 8 9 10 11 12 1 23 4 56 7 8 9 10 11 12 Plot Plot Normal irrigation Deficit irrigation Terminal drought
  15. 15. Remote Sensing • Crop statistics / areas: - High resolution satellite imagery (SPOT, 10 and 5 m) - Digital processing to discriminate small sweet potato fields from others - Results indicate only 63% of crop area in national statistics - Seeking collaboration for commodity atlasses!
