Critical for digital innovation in the sector of agriculture, open data is diverse across different agricultural fields. Fourteen dataset categories are listed as important to be assessed for openness in Croatian open data ecosystem using the TODO readiness framework. Governmental responsibility to collect, maintain and enable timely, comprehensive, comparable and interoperable data is supported by Interdisciplinary research group focused on open data founded in 2020 at University of Zagreb Faculty of Agriculture. Connecting agriculture data to specific stakeholder needs depends upon defining the six common policies for the specific agricultural fields. Of the six policies empowering the small producers is emphasized. Preliminary landscaping results show the Open data portal (open.gov.hr) is not being used by the central or other government organizations of the agriculture sector. Data sets and data files available via the internet pages of the Ministry of agriculture, the Croatian agency for agriculture and food, as well as the Paying Agency for Agriculture, Fisheries and Rural Development are using predominately closed file formats. Databases and applications of the mentioned organizations curated for diverse target groups provide access with registration and no information on how users can be registered. NGOs are also providing data and portals in the role of citizen science that can be useful for the sector (e.g. biologer.hr). Centers of excellence provide and curate databases and provide portals of good spatial data quality (e.g. cpgrd.hapih.hr). Data literacy assessment of the sector based on the literacy provided by the courses of Faculty of agriculture shows developing digital competences of the students and developing data literacy of the lecturers is not the focus of the institution. Additionally, the technical and conceptual skills required to understand and effectively use data, and to combine domain knowledge with data literacy is present in 8% of the undergraduate and 24% of the master courses according to the ECTS catalogue. In conclusion, open data research of the agricultural sector should focus on identifying distinct data needs across different fields with emphasis on the small producers. Developing open data ecosystem in the sector of agriculture in Croatia requires raising of the data literacy in the sector and empowering the governmental institutions in upgrading current level of open data provision by national and local-level consultations and the uptake of good examples and synergy with institutions of the sector of nature and environment.
