1. U.S. Department of the Interior U.S. Geological Survey Monthly Progress for Africa GCEV2 Jun Xiong 19 March, 2015

2. Promotion of Tanzania Products  Demonstration of GCP(1-4)-QKM, Tanzania, 2014 to local government officials on Mar 5 th, by FAO collaborator  Agreement of data sharing signed between USGS and FAO.  Moving ahead: 1) Training local officers to collect ground points using mobile app 2) Pilot 30m products in 1-2 regions of Tanzania for field- scale application & validation before this July

3. Field work in Pietersmertizburg, South Africa  Prasad visited South Africa in early March.  Samples created based on ground investigation, photos and Google Earth

4. Field work in Pietersmertizburg, South Africa

5. Reference map in Tanzania, 2013  Done by ICRISAT collaborator  Expert supervised-SMTs  Details about crop type/intensity, irrigated/rainfed, consistent with GFSAD scheme  Help to refine our products  Help to pilot work in Tanzania 30m products

6. Landuse map in KNZ province, South Africa, 2011  Using SPOT5 data(20m)  Provided by KZN wildlife  Different categories  Also available in 2008  aerial photos, ground points available  Help to refine our products

7. Comparable with FAO statistics?  GCP2014: GCP4-QKM, Africa, 2014, v1 (Reproject)  FAOStat: http://faostat3.fao.org/download/Q/QC/E, summed up "Harvest area" of aggregated crops classes Nigeria Congo_DRC South Sudan Tanzania

8. Problems  Sub-pixel Area on 250m pixels (Prasad 2007)  Repeated computing in FAO statistics  Single / double crops aggregation Thenkabail, P. S., Biradar, C.
