From the perspective of ICT uptake and the objectives of the project, we must conclude that the objectives have been reached: people have been trained, CGMS has been setup and calibrated and the system is running operationally. Nevertheless, from a thematic perspective we must conclude that the performance of CGMS for yield prediction is insufficient to be directly useful for wheat yield prediction in Anhui. The most important reason is that the yield variability in Anhui is probably driven by factors that are not included in the crop biophysical simulations of CGMS (disease, extreme weather). Given the thematic difficulties described above and the operational difficulties related to weather data in China , a conclusion that may be drawn is that the CGMS approach is not the most “rewarding” or “efficient” approach in Anhui for yield forecasting purposes. Also given the good results that were obtained with satellite-based indicators in Anhui (Work Package 4), it should concluded that remote sensing is a more effective approach in Anhui compared to a modelling approach. Nevertheless, as stated in the section 4.4, the combination of analysis of meteorological records and satellite observations is regarded to be a very useful tool by partner AIFER and they will further develop this part of CGMS for crop insurance purposes. Moreover, further developments in crop simulation modelling such as currently ongoing in AgMIP may lead to new model versions that have better explanatory power compared to the WOFOST version currently implementation in CGMS.

Introduction The overall goal of the E-Agri proposal to support to the uptake of European ICT research results in developing economies. The objective can be realized by setting up an advanced European E-agriculture service in two developing economies, Morocco and China, by means of crop monitoring and yield forecasting. In the work package 2 of the E-Agri project, the focus is on the implementation of the European Crop Growth Monitoring System (CGMS) for wheat monitoring and yield forecasting in two target regions: Morocco and the Huaibei region in Anhui province in China. This deliverable describes the results from the piloting phase of the CGMS implementation in Anhui province in China. First of all, gives an overview of the final implementation of the Crop Growth Monitoring System that has been set up at AIFER. Next, it describes the implementation of the different processing steps that are distinguished in the processing chain and the CGMS Viewer that has been set up to analyse results from the CGMS processing chain at AIFER. Finally, a short analysis is made of the operations that have been carried out, difficulties encountered and the socio-economic impact is described briefly.

Spatial schematization The spatial schemation of the CGMS Anhui was discussed in the Deliverable D23.1 “ Anhui_CGMS_usability_report” and will be briefly described here as some changes have been implemented compared to the initial setup described. *#HN-AY Legend SD-YZ *# meteo_stations *# meteo_stations JS-GYU Anhui_Province_boundary SD-DT *# *# Non-arable Arable land HN-ZZ *# JS-XZ 25km CGMS grid *# AH-BZ *# Huaibei District Suzhou District JS-DT Bozhou District Bengbu District *# AH-BB HN-ZM *# Fuyang District *# Huainan District JS-NJ *# HN-XY AH-HF *# *# Figure 1. Spatial schematization of the CGMS-Anhui. 2.1.1. China CGMS grid The CGMS implementation for huaibei plain in Anhui uses a grid with cells of 25x25 km which is defined in an Albers Conical Equal Area projection. This grid is defined for the whole of China and is also used by the Institute of Agricultural Resources and Regional Planning of the Chinese Academy of Agricultural Sciences. Also the grid numbers are identical which facilitates exchanging data at the level of the grid between CAAS and AIFER.
