Roughly 22 percent of Ukraines farmland– including 28 percent of winter season crops and 18 percent of summer crops– is under Russian control, according to NASA Harvests analysis. Summer season crops, primarily maize and sunflower, are grown more widely in western and northern Ukraine than winter crops. A healthy crop in the ground, nevertheless, does not ensure the crop will be harvested and sent to market. Winter crops– including canola, barley, and wheat– are prepared for harvest, and spring-planted crops will also need harvesting. NASA Harvest is working directly with Ukraines Ministry of Agriculture and the ESA WorldCereal consortium to help evaluate crop planting, harvest, and yields.
Russia had invaded Ukraine. With the war came tanks rolling through fields, farmland covered with mines, and artillery shells raining down on crops. Even farmers far from the front lines viewed tens of millions of loads of grain and other agricultural goods sit inactive in ports and silos due to a Russian marine blockade.
” The worlds breadbasket is at war,” said Inbal Becker-Reshef, director of NASAs Harvest program. Prior to the war, Ukraine offered 46 percent of global sunflower oil exports, 9 percent of the wheat exports, 17 percent of the barley, and 12 percent of the maize on worldwide markets, according to data from the U.S. Foreign Agricultural Service. (Ukraine and Russia together represented 73 percent of sunflower oil exports, 33 percent of wheat, and 27 percent of barley.) The previous few months have considerably interfered with that circulation of food.
” Were in the starting stages of a rolling food crisis that will likely impact every nation and person in the world in some way,” stated Becker-Reshef. For some populations, this could imply greater prices or missing products at the supermarket. For others, history suggests it could indicate more severe food lacks.

For more than a decade, Becker-Reshef and other NASA-funded scientists have actually been developing ingenious satellite-based techniques to keep an eye on commodity crops such as wheat and maize in Ukraine. The interdisciplinary group collects and evaluates environmental, economic, and social science data in order to improve agriculture-related decision-making all over the world. With the arrival of war, such tools could play a crucial role in preventing and expecting food scarcities and starvations.
Approximately 22 percent of Ukraines farmland– consisting of 28 percent of winter season crops and 18 percent of summertime crops– is under Russian control, according to NASA Harvests analysis. Summer crops, generally maize and sunflower, are grown more commonly in western and northern Ukraine than winter crops.
The NASA Harvest group, with international partners from the GEO Global Agricultural Monitoring (GEOGLAM) effort, measure multiple environmental elements– including rainfall, soil wetness, and temperature level– to evaluate the health of crops and anticipate end-of-season yields. “After a slow start in the spring due to dry weather condition and a cold spell, growing conditions have been primarily beneficial and the crops caught up nicely,” Becker-Reshef stated.
Satellite measurements of the “greenness” of crops– the Normalized Difference Vegetation Index (NDVI)– are necessary for NASA Harvests analysis. The chart listed below offers a photo of growing conditions in the Mykolaiv oblast, one of Ukraines largest manufacturers and exporters of wheat.
The scientists have actually likewise established models, such as the Agriculture Remotely-Sensed Yield Algorithm (ARYA), that anticipate yields by blending measures of NDVI with data about environmental conditions during the growing season from NASAs MERRA-2 reanalysis dataset. The models likewise integrate comprehensive crop maps based upon MODIS, Sentinel-2, and Landsat observations and confirmed by field studies.
” Taking all of that into account, the data indicate that Ukraine is on track for a winter wheat yield of about 4.1 metric lots per hectare,” stated Becker-Reshef. “Thats not rather as high as the record-breaking wheat crop in 2021, however its still a large crop provided the circumstances.” The photo below shows winter season wheat near Chernihiv in June 2022.
A healthy crop in the ground, however, does not guarantee the crop will be gathered and sent to market. A marine blockade has actually stopped Ukraine from exporting goods by ship, halting much of the countrys ability to offer grain, discussed Sergii Skakun, a NASA and University of Maryland scientist who grew up in Ukraine and spent several years with Ukraines Space Research Institute. Skakun has actually been studying how military conflict impacted farmers and farmland in the Donbas area of eastern Ukraine because battling broke out in 2014.
” In some areas, unexploded ordnance and mines might make farming impossible in the brief term,” Skakun stated. “In vacant locations, the naval blockade of the ports and skyrocketing fuel prices pose massive obstacles for the upcoming harvests.”.
Winter wheat.
Global food prices were already rising rapidly prior to the war due to provide chain disruptions from the COVID-19 pandemic and increasing need for food. In spite of some relief in current months, the rate of price increases has actually been speeding up for a number of key crops, particularly cereals, according to the UNs Food and Agriculture Organization.
The months in between July and October are generally some of the busiest for Ukrainian farmers. Winter season crops– including barley, canola, and wheat– are prepared for harvest, and spring-planted crops will also need harvesting. Next years winter crops should be planted by November.
” Will all of that occur this year in the middle of a war? Thats the million-dollar concern,” said Skakun. “Nobody knows how this is going to play out, however I do know the NASA Harvest group will be tracking the harvest season carefully. Satellites are one of the very best ways to keep an eye on Ukraines crops provided all the risks on the ground.”.
Mykolaiv is Ukraines highest-volume port for grain, typically dealing with about 40 percent of exports. Ships have actually historically brought about 97 percent of Ukraines grain exports, so all ports have actually seen sharp drops in volume this year.

This map reveals the distribution of summertime and winter crops in Ukraine as of June 13, 2022. It likewise reveals where farmers were operating easily and where their lands were under Russian control. It is based on information from Planet Labs satellites and the European Space Agencys Sentinel-2 mission that was processed and examined by NASA Harvest.
NASA Harvest scientists utilize satellite observations and economic information to track how the Russia-Ukraine conflict is disrupting the international food system.
When farmers in Ukraine planted wheat, canola, barley, and rye in the fall of 2021, their concerns were relatively regular: would dry weather or increasing fertilizer costs cut into their yields and revenues? By the time those winter crops emerged from inactivity in the spring of 2022, life in Ukraine had actually turned totally upside down.
” The ports are vital,” said Gary Eilerts, a NASA Harvest advisor and analyst who focuses on developing early warning systems for food lacks and famines. “Ukraine is doing what it can to export more goods via train or truck, but these other modes can just manage a little portion of whats being in the fields and will require to be harvested.”.
The secret to avoiding interruptions in the food supply will be the schedule of prompt data about crop prospects and about the cost and distribution of crucial goods. NASA Harvest is working straight with Ukraines Ministry of Agriculture and the ESA WorldCereal consortium to help examine crop planting, harvest, and yields. They have actually also established structured tools– such as the Agmet Earth Observation Indicators and the Harvest2Market website– that make pertinent crop and financial information offered to analysts all over the world.
NASA Harvest crop data likewise flows to numerous partner organizations that keep track of and react to emerging food scarcities and starvations. Partners consist of the Famine Early Warning Systems Network (FEWS NET), the Agricultural Market Information System (AMIS), and the UN Food and Agriculture Organization.
Interruptions in production and distribution of goods from Ukraine and Russia have actually currently been a shock to the international food system. Nations currently involved in conflict and dealing with major food lacks are amongst the most susceptible. Approximately 30 African, Middle Eastern, and South Asian countries– some of which are chronically food insecure– source at least 20 percent of their agricultural product imports from Ukraine or Russia.
” For the minute, a expense of living crisis is more visible than a food shortage crisis in most locations,” kept in mind Eilerts in a current blog site post. That could change if Ukraines goods stay out of international markets or if major cereal-producing countries have bad harvests. “We are at the beginning of what might be a long-term disruption.”.
