When Russia launched its full-scale invasion of Ukraine in February 2022, much of the country’s winter wheat and rapeseed had already been in the ground for months. Planted the previous fall and normally harvested the following summer, the
NASA Harvest is joining Mathematica and the University of Maryland in a new Gates Foundation-funded project to develop an AI-powered tool designed to help agricultural organizations and development agencies apply research evidence to decisi
Qadir is recognized for applying satellite remote sensing and machine learning to agricultural challenges in data-sparse regions. NASA Harvest scientist and Assistant Research Professor at the University of Maryland, Abdul Qadir has been se
Satellites can tell us more about a field than whether it is green or bare. By tracing how vegetation changes over time, repeated observations can reveal when crops begin growing, when they reach their seasonal peak, when crop senescence be
Since Russia’s invasion of Ukraine in 2022, NASA Harvest researchers have used satellite data to track how the war is affecting one of the world’s major agricultural producers. That work has included mapping field boundaries and crop types,
Food security analysts often need to understand how a disruption in one part of the food system can affect crops, trade, and prices elsewhere. Events like drought, conflict, or severe storms can reduce crop production, tighten fertilizer su
In much of the world, we don’t have reliable maps of individual farm fields. We know where crops are grown, but not where one field ends and another begins. These field boundaries, or the outlines of individual field farm fields, are the un
NASA Harvest joined NASA Acres and other NASA Earth science teams at this year’s National 4-H Conference Youth Career Fair, where students from across the country gathered in Washington, D.C. to explore leadership, service, and career pathw
NASA Harvest produces crop yield estimates for a range of uses, from regional food security monitoring to field-level decision support. There is no single model that works best across all of these cases. The choice depends on what data are
Reliable crop production estimates shape many decisions in food security planning. Governments use them to anticipate shortages, guide imports, and coordinate response programs. Yet in many low- and lower-middle-income countries dominated b
Imagine you are working inside a ministry of agriculture and need to know how many farmers are planting drought-tolerant sorghum, a crop that matters for resilience and nutrition, but is often grouped into broad statistical categories or le
A new Handbook on Remote Sensing for Agricultural Statistics has been released by the United Nations. NASA Harvest is pleased to have contributed to this effort and to share it with our community. The handbook speaks directly to a problem w
