Investing in Saltwater Agriculture: Introduction (04:59)
Hazel Henderson discusses the potential for developing halophytes to address freshwater scarcity, capture CO2, and utilize desert and scrublands. Investors following the UN's Sustainable Development Goals have a multi-billion dollar opportunity.
Halophytes as a Resource (06:07)
NASA Chief Scientist Dennis Bushnell explains how saltwater agriculture can help solve land, water, food, energy and climate issues. Crops can be produced as biomass, sequester up to 19% of CO2, need little fertilizer, and can be grown in deserts.
Barriers to Saltwater Agriculture (06:35)
Halophytes either grow in seawater or in aquaculture. Lack of farmer training or market are temporary issues. Bushnell cites a feasibility study for growing aquaculture halophytes in the Gulf of Mexico. Solar energy is becoming cheap for pumping sea water.
Suitable Halophyte Agricultural Locations (05:04)
There are saline aquifers under deserts such as the Sahara; cultivating saltwater crops would increase freshwater rainfall. Henderson discusses limitations of focusing investment on fresh water resources. Halophyte farming is a win-win-win situation and would also provide meat substitutes.
Disruptive Technology (03:30)
Bushnell predicts resistance among freshwater farmers. Halophyte markets and products are both lacking, but he compares the potential market to the size of Microsoft and Amazon. Henderson sees the shift to halophyte agriculture as inevitable, like the solar age.
