3.2 Country Analysis
This section presents CropWatch analyses for each of thirty key countries (China is addressed in Chapter 4). The maps refer to crop growing areas only and include: (a) Graph for the phenology of major crops; (b) Crop condition development graph based on NDVI average over crop areas at national scale, comparing the April-July 2017 period to the previous season and the five-year average (5YA) and maximum; (c) Maximum VCI (over arable land mask) for April-July 2017 by pixel; (d) Spatial NDVI patterns up to July 2017 according to local cropping patterns and compared to the 5YA; and (e) NDVI profiles associated with the spatial pattern under (d). Next, separate graphs (labeled as figures (f), (g), and subsequent letters) are included to illustrate crop condition development graphs based on NDVI average over crop areas for different regions within the country, again comparing the April-July 2017 period to the previous season and the five-year average (5YA) and maximum.
In addition, please see also Annexes A and B for additional information about indicator values and production estimates by country. Country agricultural profiles are posted on www.cropwatch.com.cn.
