Help us map global agricultural field sizes!

We are pleased to announce the launch of our new citizen science Field Size Campaign! We need your help to map the size of agricultural lands across our planet. Mapping field sizes provides key insights on many agricultural themes, including farming practices and their connections with nutritional diversity. Field size mapping also provides information about the appropriate resolution of satellite images for monitoring crops. Your participation in this campaign will contribute to global agricultural monitoring to help tackle food security challenges. Plus, you can win great prizes and co-authorship!

The focus of this Campaign is to collect detailed information on agricultural field size, for over 100,000 locations globally, to create an improved global field size map.

The top 25 contributors will win prizes!

  • The top 10 contributors on the leaderboard will be offered a choice between:
    • An Amazon voucher (of value from 100 to 650 Euros), OR, alternatively,
    • A reduced Amazon voucher (of value from 50 to 550 Euros) AND co-authorship on a scientific paper summarizing and making openly available the information collected.
  • Contributors ranking between 11 and 25 on the leaderboard will be offered a choice between:
    • An Amazon voucher of 25 or 50 Euros, OR, alternatively,
    • Co-authorship on a scientific paper
    Only the top 10 contributors will have the option of combining both co-authorship and an Amazon voucher. All active contributors will earn a Certificate of Achievement from IIASA, a leading global think tank. The campaign will finish as soon as all points are validated.

IIASA's Field Size Campaign will launch within the project, "SIGMA: Stimulating Innovation for Global Monitoring of Agriculture and its Impact on the Environment in support of GEOGLAM", funded by the European Commission's Seventh Framework Program (FP7). This project develops innovative methods and indicators for global monitoring and evaluates the environmental impacts of future changes in agriculture, whether through improved technologies that lead to increased yields or through the expansion of cropland areas. The SIGMA project activities support GEOGLAM, an initiative of the Group on Earth Observations Global Agricultural Monitoring, launched by the G20 Agriculture Ministers in June 2011 in Paris, to strengthen global agricultural monitoring, by improving the use of remote sensing tools for crop production projections and weather forecasting. A key component of the project is capacity building, providing training workshops and learning materials on the latest tools and methods for improving agricultural monitoring.
