Big data and open data are transforming science and agriculture. Making agricultural data openly available online as open data can generate economic benefits and help solve sustainability problems. It allows for new types of analyses that can provide insights into issues like food production and genetic variations. However, open data also faces challenges like only benefiting large players and lack of data standards and interoperability. The GODAN partnership advocates for making agricultural data globally available as open data to address issues like these through working groups and over 450 partners worldwide.
