Why saline agriculture?
$ 27 billion crop salt damage
70 % used by agriculture
95 % in developing countries
20 % irrigated areas salt affected
1 billion ha salt affected About 97 % salt water
2 % fresh
> 1 % available
2000 ha per day

Adapt farming systems to higher salinity levels
Salt tolerant crops + soil salinity management

First “quick scan” 2 salt concentrations, many different varieties
In 2017 screening of 100 Brassica + 80 potato varieties
* 2016: 80 lettuce varieties, 45 strawberry varieties
* 2015: 266 potato varieties

Up-scaling and implementation
Focus in cultivation methods and market development

Salinity tolerance reaches higher than common believe
Increase crop production under saline condition is possible
Seeing is believing, social learning for up scaling
ha for a new
SA not only contributes to food security, but also revalue salt
affected farmlands, recovery local economies and prevent
climate migrations
