May 2020 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 January to April 2020, 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 national winter crop production and trade prospects (import/export) of major crops. The focus section reports on the first early outlook of crop production for 2020, as well as sections on recent disaster events, Drought impacts on rice production in lower Mekong river, and an update on El Niño.
Key messages from the report:
- Weather conditions were generally favorable in most production regions. Temperatures were much warmer than average, especially in Europe and Russia.
- Spring green up in Europe was early. Dry conditions in March and April limited the yield potential for winter wheat in most of Europe and especially in the Ukraine.
- Conditions in maize and soybean production regions in South-America were generally favorable. As compared to last year, similar to slightly higher production levels for maize and soybean are expected.
- The dry season rice production in mainland South-East Asia suffered from a severe water shortage due to below-average rainfall.
- The situation for China was generally favorable. Winter wheat received above average rainfall and a production increase by 4% is expected. Planting of rice is on track.
IntroductionThis CropWatch bulletin summarizes global crop condition developments and agroclimatic factors from January 1st,2020 to April 30th, 2020 through 4 zoom in from a global overview of agroclimatic indicators (Chapter 1) to detailed descriptions of crop and environmental conditions in large production zones (Chapter 2), to individual country analyses covering 42 major producers and exporters including agro-ecological zones (Chapter 3) and China (Chapter 4). A special focus section is included in Chapter 5, presents crop production for 2020, disaster events and an update on El Niño. This first part of the report includes the cover, table of contents, abbreviations, a short overview of the different sections of the bulletin and executive summary.Download
Chapter 1. Global agroclimatic patternsChapter 1 describes the CropWatch agroclimatic indicators for rainfall (RAIN), temperature (TEMP), and radiation (RADPAR), along with the agronomic indicator for potential biomass (BIOMSS) for sixty-five global Mapping and Reporting Units (MRU). Indicator values for all MRUs are provided in Annex A.Download
Chapter 2. Crop and environmental conditions in major production zonesChapter 2 presents the same indicators—RAIN, TEMP, RADPAR, and BIOMSS—used in Chapter 1 and combines them with agronomic indicators—cropped arable land fraction (CALF), maximum vegetation condition index (VCIx), and minimum vegetation health index (VHIn)—to describe crop and environmental conditions in six global major production zones (MPZ): West Africa, North America, South America, South and southeast Asia, Western Europe, and Central Europe to western Russia. (See also Annex B for more information about these zones.)Download
Chapter 3. Main producing and exporting countriesBuilding on the global patterns presented in previous chapters, this chapter assesses the situation of crops in 42 key countries that represent the global major producers and exporters or otherwise are of global or CropWatch relevance. First, the overview section (3.1) pays attention to all countries worldwide, to provide some spatial and thematic detail to the overall features described in section 1.1. In section 3.2, more detail is provided for each of the CropWatch monitored countries, including analyses by key agro-ecological zones within the country. Additional information about indicators per country is provided in Annex A.Download
Chapter 4. ChinaAfter a brief overview of the agroclimatic and agronomic conditions in China over the reporting period (section 4.1), Chapter 4 presents an updated estimate of national winter crop production (4.2) and describes the situation by region, focusing on the seven most productive agro-ecological regions of the east and south: Northeast China, Inner Mongolia, Huanghuaihai, Loess region, Lower Yangtze, Southwest China, and Southern China (4.3). Section 4.4 describes trade prospects (import/export) of major crops. Additional information on the agroclimatic indicators for agriculturally important Chinese provinces are listed in table A.11 in Annex A.Download
Chapter 5 Focus and perspectivesBuilding on the CropWatch analyses presented in chapters 1 through 4, this chapter presents first early outlook of crop production for 2020 (section 5.1), as well as sections on recent disaster events (section 5.2), drought impacts on rice production in lower Mekong river (5.3) and an update on El Niño (5.4).Download
Annex A Agroclimatic indicatorsTables in this Annex provide additional information about the agroclimatic indicators—RAIN, TEMP, and RADPAR—as well as BIOMSS for the various CropWatch spatial units. Those units include the Mapping and Reporting Units (MRU); the forty-three main producing and exporting countries; and regions or provinces within large countries—Argentina, Australia, Brazil, Canada, India, Kazakhstan, Russia, and the United States; and China.Download
Annex B Quick reference guide to CropWatch indicators, spatial units and methodologiesAnnex B presents a brief overview of the CropWatch indicators and spatial units (including the MRUs, MPZs, and countries), along with a description of the CropWatch production estimation methodology and methodology to determine the severity of the occurrence.Download
