OverviewCrop and environmental conditions in major production zones

Authors: 超级管理员 | Edit: Miao

Chapter 2 presents thesame indicators—RAIN, TEMP, RADPAR, and BIOMSS—used in Chapter 1, and combinesthem with the agronomic indicators—cropped arable land fraction (CALF) andmaximum vegetation condition index (VCIx)—to describe crop condition in six MajorProduction Zones (MPZ) across all continents. For more information about thesezones and methodologies used, see the quick reference guide in Annex C as wellas the CropWatch bulletin online resources at www.cropwatch.com.cn.

2.1 Overview

Tables 2.1 and 2.2 present an overview of the agroclimatic (table 2.1) and agronomic (table 2.2) 
indicators for each of the six MPZs, comparing the indicators to theirfourteen- and five-year averages.

Note:Departures are expressed in relative terms (percentage) for all variables,except for temperature, for which absolute departure in degrees Celsius isgiven. Zero means no change from the average value; relative departures arecalculated as (C-R)/R*100, with C=current value and R=reference value, which isthe fourteen-year average (14YA) for the same period (October-January) for2001-14.

Note:Departures are expressed in relative terms (percentage) for all variables. 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 the five-year(5YA) average for the same period (October-January) for 2010-2014.
