Two high school students from Singapore Cambodia International Academy (SCIA) and one student from Preah Sisowath High School were nominated by Ministry of Education, Youth and Sport (MoEYS) to participate in the 34th China Adolescents Science and Technology Innovation Contest (CASTIC) in Macau, China in July. They won 3rd place in the International Projects category and this is their winning project – Recirculating Aquatic System of Agriculture (“RASA”).
Worldwide population growth, along with rising incomes in developing countries, are driving up global food demand and exhausting world’s agricultural resources.
‘RASA’, the award-winning innovation at the 34th CASTIC, aims to introduce a sustainable aquatic farming system which increases farm productivity while reducing the use of natural resources.
Ammonia-rich fish waste produced by the fish in the system can be turned into nitrate needed for the plants, and dirty water can be reused in the hydroponic tank where the plants are grown underwater.
All these are done without compromising the quality and freshness of the vegetation.
