A new breed of farmer is appearing in Singapore.

They are using high-tech and high-yield methods to transform their work from back-breaking labour into lucrative businesses.

From running indoor vertical vegetable farms that grow crops in stacked layers, to raising fitter fish that are robust against aquatic diseases, farmers here are finding ways to overcome the limitations of traditional farming.

Dr Jonatan A. Lassa, a Research Fellow at the S. Rajaratnam School of International Studies, Nanyang Technological University, who researches food and environmental security issues, said that growing crops in a controlled environment can have several advantages, including a lower carbon footprint and less water wastage.
