The goal of GEOGLAM is to strengthen the international community’s capacity to produce and disseminate relevant, timely and accurate forecasts of agricultural production at national, regional and global scales through the use of Earth Observations (EO), which include satellite and ground-based observations. The GEOGLAM initiative is designed to build on existing agricultural monitoring programs and initiatives at national, regional and global levels and to enhance and strengthen them through international networking, operationally focused research, and data/method sharing. - Measures to slow the spread of COVID-19 affected the food supply chain in many ways, including the availability of inputs, labor, transport, and cross-border trade. The Group on Earth Observation's Global Agricultural Monitoring Initiative (GEOGLAM) Global Crop Monitor uses remote sensing data like global precipitation and soil moisture measurements to help reduce uncertainty, promote market transparency, and provide early warning for crop failures through multi-agency collaboration. During the pandemic, this tool - developed in conjunction with NASA's food and agriculture program (NASA Harvest), ESA (European Space Agency) and JAXA, Japan Aerospace Exploration Agency - is increasingly used in lieu of on-the-ground validation of crop conditions. + Presented here are GEOGLAM Crop Monitor data, which provides an international and transparent multi-source, consensus assessment of crop growing conditions, status, and agro-climatic conditions, likely to impact global production. It covers the four primary crop types (wheat, maize, rice, and soy) within the main agricultural producing regions of countries participating in the [Agricultural Market Information System (AMIS)](https://www.amis-outlook.org/amis-about/en/). These assessments have been produced operationally since September 2013 and are published in the [AMIS Market Monitor Bulletin](https://www.amis-outlook.org/index.php?id=48514). The Crop Monitor reports provide cartographic and textual summaries of crop conditions as of the 28th of each month, according to crop type. Assessments from January 2020 and onward are available to view on Earth.gov. - Data from the GEOGLAM Crop Monitor inform two different agricultural tools that have helped lessen global concerns over food security during the novel coronavirus pandemic: the Agricultural Market Information System (AMIS) and the Crop Monitor for Early Warning (CM4EW). AMIS provides agricultural information based on remote sensing observations for the major producing nations of four primary crops - wheat, maize, rice, and soybeans. CM4EW provides agricultural data for countries at higher risk of food insecurity. - -

While many countries experienced lockdowns and travel bans as coronavirus spread, most farmers were able to continue operations due to the rural nature of most farm communities and the relatively less labor-intensive cultivation techniques associated with key crops. + *Crop Condition Class Definitions:* + - **Exceptional**: Conditions are much better than average at time of reporting, where the average is the mean conditions over the most recent 5 years. This label is used only during the grain-filling through harvest stages. + - **Favorable**: Conditions range from slightly below to slightly above average at reporting time. + - **Watch**: Conditions are not far from average but there is a potential risk to final yields. There is still time and possibility for the crop to recover to average conditions if the ground situation improves. This label is only used during the planting-early vegetative and the vegetative-reproductive stages. + - **Poor**: Crop conditions are well below average. Crop yields are likely to be 5% below average. This is only used when conditions are not likely to be able to recover, and impact on yields is likely. + - **Out of Season**: Crops are not currently planted or in development during this time. + - **No Data**: No reliable source of data is available at this time. - However, the spread of the coronavirus did have an impact on the ability of governments and agricultural organizations to perform in-person field surveys of sowing, crop progress, and harvesting. This reinforced the need for strong remote sensing capabilities. Satellite-based information from AMIS helped confirm that global food production during the early parts of the pandemic was secure, leading to the resumption of normal trade flows after some large producer and export countries issued temporary trade restrictions. - - "Assessing the global supply situation and being able to predict unexpected shortfalls is the single most important task to guarantee global food security,” explained Abdolreza Abbassian, Secretary of AMIS and a U.N. Food and Agriculture Organization senior economist. “However, such assessments must be evidence-based and credible, and this is where reliance on timely information from remote sensing plays a fundamental role.” -

However, production was disrupted in some areas through COVID-19 restrictions, causing agricultural labor supply shortages and disrupting supply chains, limiting farmers' access to seeds, fertilizers, and other inputs. This resulted in reported declines in planted area and yields in Ethiopia, Somalia and elsewhere across the region, and it will be critical to continue to monitor the situation and to provide timely and evidence driven crop assessments. - -

[https://doi.org/10.3390/rs70201461](https://doi.org/10.3390/rs70201461) - In Southern Asia, the GEOGLAM crop condition assessments are coordinated by the Asian Rice Crop Estimation & Monitoring (Asia-RiCE) initiative led by the Japan Aerospace Exploration Agency (JAXA) with inputs from the region's national ministries of agriculture. COVID-19 impacted the region by restricting the ability of governments to do field surveys, particularly during the height of the outbreak. + The findings and conclusions in the GEOGLAM reports are consensual statements from the GEOGLAM experts, and do not necessarily reflect those of the individual agencies represented by these experts. - Currently, on the northern side of Southeast Asia, the dry-season rice has come to a close and the wet-season rice (main producing season) is underway. The dry season, which ended in May-June, was affected by persistent dry conditions that drove down yields and planted area in Myanmar, Thailand, and Laos. The wet-season rice began under generally favorable conditions, with ample rainfall in most areas except for southern Vietnam. Additionally, there has been some flooding in Bangladesh. + Map data sources: Major crop type areas based on the IFPRI/IIASA SPAM 2005 beta release (2013), USDA/NASS 2013 CDL, 2013 AAFC Annual Crop Inventory Map, GLAM/UMD, GLAD/UMD, Australian Land Use and Management Classification (Version 7), SIAP, ARC, and JRC. The GEOGLAM crop calendars are compiled with information from AAFC, ABARES, ARC, Asia RiCE, Bolsa de cereales, CONAB, INPE, JRC, FAO, FEWS NET, IKI, INTA, SIAP, UHMC, USDA FAS, and USDA NASS. - In the southern side (Indonesia), during the wet-season, reduced rainfall delayed the sowing of the rice and eventually resulted in less total sown area and a reduction in yields. As a consequence of the delay in the wet-season, the sowing of dry-season rice was delayed. Despite the delay, good rainfall continued into the traditional dry season. + All data displayed in Earth.gov has been transformed from the original format into Cloud Optimized GeoTIFF ([COG](https://www.cogeo.org/)).
