This plan reveals the distribution of summer season and iciness vegetation in Ukraine as of June 13, 2022. It moreover reveals where farmers were working freely and where their lands were under Russian defend watch over. It is in accordance with knowledge from Planet Labs satellites and the European Living Company’s Sentinel-2 mission that was as soon as processed and analyzed by NASA Harvest.
NASA Harvest scientists spend satellite observations and economic knowledge to trace how the Russia-Ukraine battle is disrupting the worldwide food machine.
When farmers in Ukraine planted wheat, canola, barley, and rye in the autumn of 2021, their worries were comparatively routine: would dry weather or rising fertilizer costs carve into their yields and earnings? By the point those iciness vegetation emerged from dormancy in the spring of 2022, lifestyles in Ukraine had turned fully upside down.
“The sector’s breadbasket is at battle.” — Inbal Becker-Reshef
Russia had invaded Ukraine. With the battle came tanks rolling thru fields, farmland covered with mines, and artillery shells raining down on vegetation. Fuel and fertilizer costs skyrocketed. Labor grew scarce. Some farmers left to enroll in the fighting; others died or fled after their villages were bombarded. Even farmers removed from the entrance lines watched tens of millions of hundreds grain and various agricultural items sit down dormant in silos and ports because of the a Russian naval blockade. Because the fight raged on, even grain and vegetable oil storage facilities grew to change into targets.
“The sector’s breadbasket is at battle,” acknowledged Inbal Becker-Reshef, director of NASA’s Harvest program. Sooner than the battle, Ukraine supplied 46 p.c of global sunflower oil exports, 9 p.c of the wheat exports, 17 p.c of the barley, and 12 p.c of the maize on global markets, in accordance with knowledge from the U.S. Foreign Agricultural Carrier. (Ukraine and Russia collectively accounted for 73 p.c of sunflower oil exports, 33 p.c of wheat, and 27 p.c of barley.) The past few months beget considerably disrupted that float of food.
“We’re in the origin phases of a rolling food crisis that can probably beget an impress on every nation and person on Earth in a device,” acknowledged Becker-Reshef. For some populations, this could perchance well imply higher costs or lacking objects at the food market. For others, historical past suggests it’d imply extra acute food shortages.

For better than a decade, Becker-Reshef and various NASA-funded scientists had been increasing modern satellite-based mostly tactics to visual display unit commodity vegetation a lot like wheat and maize in Ukraine. The interdisciplinary group collects and analyzes environmental, economic, and social science knowledge in present to toughen agriculture-linked decision-making throughout the sphere. With the arrival of battle, such tools could perchance well play a key role in looking at for and fending off food shortages and famines.
The plan at the pinnacle of the page—in accordance with knowledge from Planet Labs satellites and the European Living Company’s Sentinel-2 mission that was as soon as processed and analyzed by NASA Harvest—reveals the distribution of summer season and iciness vegetation in Ukraine as of June 13, 2022. The plan moreover reveals where farmers were working freely and where their lands were under Russian defend watch over. Roughly 22 p.c of Ukraine’s farmland—collectively with 28 p.c of iciness vegetation and 18 p.c of summer season vegetation—is under Russian defend watch over, in accordance with NASA Harvest’s analysis. Summer vegetation, essentially maize and sunflower, are grown extra widely in northern and western Ukraine than iciness vegetation. (Knowledge on land occupation comes from the Institute for the Stumble on of Battle and the American Venture Institute’s Serious Threats Challenge.)
The NASA Harvest group, with global companions from the GEO International Agricultural Monitoring (GEOGLAM) initiative, measure extra than one environmental factors—collectively with precipitation, soil moisture, and temperature—to assess the well being of vegetation and never sleep for cease-of-season yields. “After a slack originate in the spring because of the dry weather and a cool spell, increasing conditions had been mostly favorable and the vegetation caught up nicely,” Becker-Reshef acknowledged.
Satellite tv for pc measurements of the “greenness” of vegetation—the Normalized Distinction Vegetation Index (NDVI)—are crucial for NASA Harvest’s analysis. The chart below presents a snapshot of increasing conditions in the Mykolaiv oblast, one amongst Ukraine’s greatest producers and exporters of wheat.
The researchers beget moreover developed objects, such because the Agriculture Remotely-Sensed Yield Algorithm (ARYA), that stay unsleeping for yields by mixing measures of NDVI with knowledge about environmental conditions for the length of the increasing season from NASA’s MERRA-2 reanalysis dataset. The objects moreover incorporate detailed slash maps in accordance with MODIS, Sentinel-2, and Landsat observations and validated by field surveys.
“Taking all of that into yarn, the knowledge ticket that Ukraine is heading in the correct direction for a iciness wheat yield of about 4.1 metric lots per hectare,” acknowledged Becker-Reshef. “That’s no longer moderately as excessive because the portray-breaking wheat slash in 2021, nonetheless it’s peaceable a huge slash given the cases.” The photograph below reveals iciness wheat advance Chernihiv in June 2022.
A wholesome slash in the floor, nonetheless, does no longer guarantee the slash will be harvested and sent to market. A naval blockade has stopped Ukraine from exporting items by ship, halting important of the nation’s skill to promote grain, defined Sergii Skakun, a NASA and University of Maryland researcher who grew up in Ukraine and spent extra than one years with Ukraine’s Living Learn Institute. Skakun has been learning how military battle affected farmers and farmland in the Donbas self-discipline of jap Ukraine since fighting broke out in 2014.
“In some areas, unexploded ordnance and mines could perchance well impress farming not likely in the rapid time duration,” Skakun acknowledged. “In unoccupied areas, the naval blockade of the ports and soaring fuel costs pose mountainous challenges for the upcoming harvests.”
Iciness wheat.
International food costs were already rising fleet sooner than the battle because of the give chain disruptions from the COVID-19 pandemic and rising ask for food. No topic some reduction in most modern months, the sail of designate increases has been accelerating for several key vegetation, specifically cereals, in accordance with the UN’s Food and Agriculture Group. (Cereals contains wheat, maize, barley, and rice.) Wheat costs beget risen by better than 10 p.c in 2022 and beget nearly doubled since 2019. Fertilizer costs beget moreover skyrocketed, that skill farmers are probably utilizing less of it and could perchance well glimpse lower yields.
The months between July and October are normally about a of the busiest for Ukrainian farmers. Iciness vegetation—collectively with wheat, barley, and canola—are ready for harvest, and spring-planted vegetation will moreover need harvesting. Next year’s iciness vegetation have to be planted by November.
“Will all of that occur this year in the heart of a battle? That’s the million-dollar quiz,” acknowledged Skakun. “No person is conscious of how that is going to play out, nonetheless I assemble know the NASA Harvest group will be monitoring the harvest season carefully. Satellites are one amongst essentially the most easy suggestions to visual display unit Ukraine’s vegetation given the total dangers on the floor.”
The Landsat 8 image above reveals fields of canola colorful in Mykolaiv oblast advance Shyrokolanivka on Would possibly perchance moreover 20, 2022. Mykolaiv is Ukraine’s perfect-quantity port for grain, normally going thru about 40 p.c of exports. (Varied predominant grain-exporting ports consist of Chornomorsk, Yuzhne, and Odesa.) Ships beget historically carried about 97 p.c of Ukraine’s grain exports, so all ports beget considered sharp drops in quantity this year.
“The ports are compulsory,” acknowledged Gary Eilerts, a NASA Harvest book and analyst who specializes in increasing early warning systems for food shortages and famines. “Ukraine is doing what it would perchance to export extra items by strategy of order or truck, nonetheless these various modes can most productive handle a puny half of what’s sitting in the fields and can have to be harvested.”
The important thing to fending off disruptions in the food provide would be the provision of well timed knowledge about slash possibilities and about the value and distribution of key items. NASA Harvest is working instantly with Ukraine’s Ministry of Agriculture and the ESA WorldCereal consortium to abet analyze slash planting, harvest, and yields. They’ve moreover developed streamlined tools—such because the Agmet Earth Commentary Indicators and the Harvest2Market portal—that impress linked slash and economic knowledge on hand to analysts throughout the sphere.
NASA Harvest slash knowledge moreover flows to several partner organizations that visual display unit and respond to emerging food shortages and famines. Companions consist of the Famine Early Warning Systems Community (FEWS NET), the Agricultural Market Knowledge System (AMIS), and the UN Food and Agriculture Group.
Disruptions in production and distribution of items from Ukraine and Russia beget already been a shock to the worldwide food machine. Countries already embroiled in battle and facing serious food shortages are amongst essentially the most vulnerable. Approximately 30 African, Heart Japanese, and South Asian worldwide locations—about a of that are chronically food terrified—provide as a minimum 20 p.c of their agricultural commodity imports from Ukraine or Russia.
“For the 2nd, a ‘cost of residing’ crisis is extra visible than a food scarcity crisis in most places,” important Eilerts in a most modern weblog submit. But that would perchance alternate if Ukraine’s items beget out of global markets or if predominant cereal-producing worldwide locations beget unhappy harvests. “We’re at the origin of what could perchance well very well be a lengthy-time duration disruption.”
