Exploring opportunities to sustain yield and nutritional quality of food crops in Brunei Darussalam under changing climate

Food and nutritional security under global climate change are among the major challenges for crop producers around the world, including Brunei, where nutritional security is already an important issue, particularly among pregnant women and children. This project will quantify the impact of climatic factors such as heat, drought, salinity, and elevated CO2 on rice and maize crops, leading towards development of efficient screening protocols. The research finding will improve our understanding of the heat and stress tolerance mechanisms in crops. We also aim to develop innovative technologies such as green nano-fertilisers (nanotechnology) for improving crop performance under current and projected hot and dry climates. The application of these technologies will be optimised under controlled and field environments for increasing yield stability and stress tolerance in crops. This project will serve as a foundation for studying crop physiology and stress tolerance mechanisms in plants, providing training opportunities for local students at UBD, and developing collaborative research links with local stakeholders and foreign institutions.
