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

Data Management / Sharing

• Genebank data management:- Linkage of in-situ & ex-situ genebank management (potato parque Cuzco)

- ‘Participatory’ GIS

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

Modeling and GIS

• Environmental Vulnerability Assessment:

- Modeling scenarios of agricultural intensification

Land Degradation (e.g. landslides, water erosion)

Nutrient depletion

Pesticide leaching

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)

Modeling and GIS

• Climate Change applications:

- Drought mapping based on RS (time series of NDVI)

Max NDVI Min NDVI Current NDVI PCC Drought Map

El Niño ‘Normal’

Drought Probability Index Drought Probability Index

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

Modeling and GIS

• Pest and Disease modeling:

- Linking pest and disease modeling with spatial predictions of environmental conditions

(e.g. Potato Tuber Moth lifecycle & Late Blight modeling linked to Climate Change)

Modeling and GIS

• Pest and Disease modeling:

- Risk mapping of Potato yellow vein virus

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)

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!
