Southeast Asia's food security is at risk due to its heavy reliance on external sources of synthetic fertilizers. The Russia-Ukraine war has further exacerbated the issue, as trade sanctions have caused fertilizer prices to surge. To address this vulnerability, Southeast Asian nations should focus on developing local and circular fertilizer production methods. Recovering nitrogen, phosphorus, and potassium domestically through innovative circular solutions, such as biofertilizers derived from insect and seaweed farming, can provide sustainable alternatives. Large-scale nutrient recovery from sewage is another promising solution, utilizing human waste to extract necessary nutrients. Countries should invest in research and development for localized solutions, provide subsidies and incentives to local fertilizer producers, and create a market for nutrient recovery solutions. By strengthening fertilizer security through these measures, Southeast Asian nations can enhance their food security and contribute to the circular economy.
