    Sea level rise is changing the agricultural landscape around the world. Fortunately, saltwater irrigation has been studied for decades, and experiments and research have grown and demonstrated the viability of some plants such as halophytes that have the potential to change our conventional food landscape. In this episode we explore questions related to salt-water irrigation such as: what types of new crops can be developed for sustainable harvest, and what techniques can be invented to succeed without additional environmental damage?

Scientists at the International Centre for Biosaline Agriculture (ICBA) are working on halophytic (salt-loving) plants, including Salicornia bigelovii samphire (pictured). It is hoped that salt-tolerant agricultural ingredients will become staples of a global diet in a world where freshwater irrigation is increasingly unstable. Credit: ICBA
