Diploma in Environmental & Marine Science (R62)


What You Will Learn

(This diploma is formed from the merger of Diploma in Environmental Science and the Diploma in Marine Science & Aquaculture)

Climate change presents a host of challenges to humanity. These include increased wildfires, rising sea levels, declining clean water supplies, reduced agricultural and seafood yields, and disease outbreaks. Passionate in making a positive impact amidst these challenges? Join us to become the next generation of leaders in sustainability!

Through the Diploma in Environmental and Marine Science (DEMS), you will be equipped with knowledge in an extensive range of topics such as earth and climate science, terrestrial and marine ecology, environmental data analysis, environmental management, sustainability reporting, and circular economy. You will also gain essential knowledge and skills to help you conserve and manage complex ecosystems through interactions with terrestrial and aquatic wildlife during external field trips and visits to RP rain garden and aquaculture research facility, Aquaria.

Specialisation tracks in Environmental Management and Technology or Aquaculture Technology which you choose in your second year, will prepare you for fast-paced roles at the forefront of developing sustainable environmental and aquaculture solutions. You will be able to apply your knowledge through industry attachments in organisations such as Wildlife Reserves Singapore, S.E.A. Aquarium, Tropical and Marine Science Institute (TMSI), National Environment Agency (NEA) and National Parks Board (NParks).


The course structure consists of general, discipline, and specialisation modules. There is also an industry orientation component.
