Genomics is a powerful tool that can identify how resilient agriculture and biological diversity will be to a changing climate. Indonesia is an island nation with a huge diversity of crops and wild plant species at risk from rising temperatures and more frequent climate extremes. RBG Kew and BRIN here aim to build a cohort of Indonesian plant scientists who employ the latest genomics methods to determine and improve the resilience of the country’s plant megadiversity to build food security.
