Chapter 2 presents the same indicators—RAIN, TEMP, RADPAR,and BIOMSS—used in Chapter 1, and combines them with the agronomic indicators—croppedarable land fraction (CALF) and maximum vegetation condition index (VCIx)—to describecrop condition in six Major Production Zones (MPZ) across all continents. Formore information about these zones and methodologies used, see the quick referenceguide in Annex C as well as the CropWatch bulletin online resources at www.cropwatch.com.cn.

| Current (mm) | Departure from 14YA (%) | Current | Departure from 14YA (°C) | Current | Departure from 14YA (%) |
West Africa | 961 | 16 | 26.5 | -0.2 | 968 | -4 |
South America | 498 | 46 | 20.5 | 0.5 | 957 | -5 |

Note: Departuresare expressed in relative terms (percentage) for all variables, except fortemperature, for which absolute departure in degrees Celsius is given. Zeromeans no change from the average value; relative departures are calculated as(C-R)/R*100, with C=current value and R=reference value, which is thefourteen-year average (14YA) for the same period (July-October) for 2001-14.

Note: Departuresare expressed in relative terms (percentage) for all variables. Zero means nochange from the average value; relative departures are calculated as(C-R)/R*100, with C=current value and R=reference value, which is the five-year(5YA) average for the same period (July-October) for 2010-2014.
