Table 1 Five seaweed demand scenarios were considered to estimate the impact of seaweed substitution on the environmental impacts of land use and the corresponding increase of sea-use change
From: Reducing global land-use pressures with seaweed farming
Scenario name | Scenario description |
|---|---|
Food | Seaweeds constitute 10% of global diets by energy content by 2050. |
Feed | Seaweeds constitute 10% of global livestock feed for ruminants, poultry and swine by energy content by 2050. Changes in feed efficiency or effects on methanogenesis in ruminants are not considered. |
Fuel | Seaweeds constitute 50% of the feedstock used to produce transport fuels by 2050. |
All | Scenarios ‘Food’, ‘Feed’ and ‘Fuel’ are all realized by 2050. |
Aspa | Asparagopsis supplements 0.5% of all ruminant diets by 2050, reduces methane production per animal by 68% and increases food conversion efficiency by 14%25 |
