Global food insecurity has already been rising, mainly due to climate change phenomena. This is aggravated by supply chain disruptions due to the war in Ukraine and economic fallout of the COVID-19 pushing food prices to an all time high. The great challenge is to adapt to climate change while trying to increase food production. Climate Smart Agriculture Technology (CSAT) is a set of agricultural practices and technologies that can boost productivity, enhance resilience and reduce GHG emissions. Central to the success of CSAT is the application of precision farming with the use of IOT sensors and aerial photography. This research examines the application of CSAT in a paddy field in Brunei Darussalam. Data from soil sensors and aerial drone imagery were used to influence better and more informed decision-making. Variable rate technology (VRT) was used to control the fertilizer application based on what was needed by the crop. Since a precise amount of fertiliser was applied, VRT can boost the efficiency of resource utilization, leading to increased crop yields and profitability. The application of CSAT in this case study saved the farmer around 60% by changing the type of fertilizer and reducing the amount used.
