Transcript

1. Mapping and analyzing maize and wheat and other scientific stuff ! Kai Sonder, Kindie Tesfaye GIS UNIT CIMMYT and many many others CGIAR CSI annual meeting ITC University of Twente Enschede 22-24 September 2014
2. Drought targeting work DTMA DSI (DROUGHT SEVERITY INDEX) ! RS (MODIS) based Global Data 2000-2011 available ! Annual values Monthly values 8 Day values ! Mu et al 2013.
3. Climate change related work CCAFS Global Futures
4. Climate change impacts on maize, 2030 Irrigated maize Rainfed maize
5. Temperature changes South Asia
6. CC Impact on rain fed wheat production
7. CC Impact on rain fed Maize production
8. Targeting new DT maize varieties in Africa
9. Remote sensing in breeding and conservation agriculture • High throughput phenotyping • Fertilizer recommendations • Crop area estimations • Field variability
10. Airborne Remote Sensing Platform for High 
 Throughput Phenotyping • AB1100 helium filled blimp. • Tethered. • L8.0m, W3.1m. • Payload approx 6 kg • Max flight height 300 m. • Max wind speed 13 m/s. ! • Astec Falcon 8, 8-rotar UAV. • Remote controlled. • 650 g payload. • Max flight height approx 130 m. • Max wind speed 10 m/s. • Airelectronics Skywalker • Autonomous flying
