FAO wins prize for geospatial project in Zimbabwe | FAO News

Rome – The Food & Agriculture Organization of the United Nations (FAO) was awarded Wednesday for its sustained effort to help Zimbabwe use satellite-tracked evidence to improve its crop production data.

FAO won the SDG Custodian Agency Prize at the seventh annual GEO SDG Awards, which recognizes the productivity, innovation, novelty & exemplary efforts in the use of Earth observations to support sustainable development.

The prizes were organized by Earth Observations for the Sustainable Development Goals (an EO4SDG Initiative under the auspices of the Group on Earth Observations (GEO), a partnership of more than 100 national governments & even more participating organizations, representing researchers, data providers & businesses. GEO coordinates a “system of systems” that includes more than 400 million open-data resources from an array of providers including NASA & the European Space Agency as well as commercial actors.

FAO helped the Government of Zimbabwe establish an Earth Observation-assisted national crop monitoring system for production of official national agricultural statistics on acreage & yield as well as drought & flood modelling.

“This multi-faceted initiative is a model for sustainable EO integration into national statistical systems, contributing directly to SDG indicators & to the resilience of Zimbabwe’s agriculture sector,” said Lorenzo de Simone, FAO’s Earth Observation for Statistics (FAO-EOSTAT) project leader.

The initiative was part of the ongoing FAO-EOSTAT programme, launched in 2019 which has expanded to more than 21 countries. It helps FAO Members use cutting-edge technologies to produce seasonal crop type maps & annual land cover maps that are standardized, accurate, granular & validated, & integrate earth observation data & tools in the production of land cover & land use statistics.

The project

The EOSTAT-Zimbabwe project, buoyed by funding from the African Development Bank (AfDB), was launched in 2023 to operationalize the use of Earth Observation (EO) data for agricultural monitoring, food security planning, disaster risk reduction, & assess the impacts of climate-related hazards.

The project has already generated Zimbabwe’s first national winter wheat map, covering 28 districts, with 95 percent overall accuracy & 96 percent precision for wheat classification. It also led to production of the first national summer crop type map, classifying 14 major crops with 77 percent overall accuracy, using the Sen4Stat system & Sentinel-2 data.

A High-Resolution Drought Monitoring System, calibrated for Zimbabwe’s crops & climate, has also been launched, allowing field-level assessment of drought severity & temporal trends.

A prototype Farmer Registry System, linking field parcel boundaries with social survey & crop type data, is being developed, enabling tracking of productivity, subsidies, & government incentive impacts.

Flood monitoring & anticipatory action systems have also been operationalized, integrated with the World Food Programme & national platforms.

ZIMSTAT, the national statistics institute, is poised to adopt a newly-created national survey frame & in-situ data collection protocol for crop type mapping. More than 25 national experts have been trained at ZIMSTAT, government ministries & other national agencies.

The tools allow for lower-cost & higher-accuracy assessments of crop acreage & other factors. A national Mapathon organized with the National University of Science & Technology contributed to the digitization of over 200,000 crop fields across 7 districts.

FAO, the custodian UN agency for 22 Sustainable Development Goal (SDG) indicators & a contributing agency for another five, is committed to leveraging the potential of digital technologies to achieve the Four Betters: better production, better nutrition, a better environment & a better life for all, leaving no one behind.
