This paper identifies key issues and obstacles faced by Sustainable AgTech startups in the Latin America and Caribbean region. Our empirical approach is based on the analysis of statistical data from the Sustainable AgTech Challenge 2021 (created and launched by UNEP and the Yield Lab Institute with Yield Lab LATAM and Universidad Austral as key partners) and interviews with various stakeholders and experts in the AgTech area. We found that the AgTech sector is providing dynamic solutions that target multiple SDGs, but that the general awareness of sustainability and how to track impacts must continue to improve for AgTech startups to maximize their contribution to sustainable agriculture, while increase their possibilities for growth and scalability. These startups still face difficulties in accessing capital and markets, as well as bureaucratic obstacles and heterogeneous regulations within the region. Finally, based on our analysis of the current state of the Sustainable AgTech sector, we propose thirteen policy recommendations focused on building a support ecosystem that maximizes innovation and the impact of AgTech startups.
