August 2021 CropWatch Bulletin is based mainly on current remote sensing inputs in addition to detailed and spatially accurate reference data about crops and their management. Focusing on the months of April to July 2021, chapters cover global, national, and regional level agroclimatic conditions and the condition of crops that were growing during this time. For China, the bulletin presents crop conditions for each of seven key agro-ecological zones, an updated estimate of trade prospects (import/export) of major crops. The focus section reports on the estimate by CropWatch for maize, rice, wheat and soybeans production in 2021, recent disaster events with an impact on agriculture, and the possibility of an El Niño event.
May 2014 CropWatch bulletin (Vol. 14, No. 2)
The May 2014 CropWatch bulletin (Vol. 14, No. 2) summarizes global crop condition developments and agroclimatic factors from January to April 2014, focusing on key crop producing and exporting areas and China. The bulletin reports on cold spells, warm spells, and droughts affecting large areas, with resulting impacts on regional and national agricultural production. Findings also include that some of the observed climatic anomalies are in line with El Niño induced weather patterns. The report lists current production estimates for maize, rice, wheat, and soybean for calendar year 2014, using CropWatch information on crop condition and areas of cropped land compared to recent years. The bulletin’s special focus is on disasters, wheat, and El Niño.
February 2014 CropWatch bulletin (Vol. 14, No. 1)
The February 2014 CropWatch bulletin (Vol. 14, No. 1) presents a global overview of crop stage and condition between October 2013 and January 2014. Using a hierarchical approach mostly based on remote sensing indicators, the bulletin describes environmental variables—rainfall, temperature, radiation, and biomass—for the globe, along with agronomic indicators—vegetation condition and health indices, ratio of uncropped arable land—for major production areas, thirty key countries, and China. The bulletin also summarizes disasters and extreme weather events over the monitoring period and presents a focus section on soybean.
November 2013 CropWatch bulletin (Vol. 13, No. 7)
The November 2013 CropWatch bulletin provides a comprehensive overview of the 2012-13 global production of wheat, rice, maize, and soybean. It is based on a thorough analysis of environmental conditions and a quantitative assessment of their impact on crops, focusing on some of the major production areas and countries, including China. The CropWatch analysis presented in the report takes advantage of newly available data, including the high quality data from the Chinese FY-3 and HJ-1 satellites, and introduces new spatial units of analysis, new methods, and several innovative remote sensing-based indicators. The report marks CropWatch’ first systematic contribution to GeoGLAM and the G20 Agricultural Market Information System (AMIS) and for the first time is released in both English and Chinese.
