SALINE AGRICULTURE A practical solution to a global problem
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
Open air lab
Texel Island, the Netherlands
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
Test facility 1 ha; 56 plots, 7 treatments, 8 replicas
Data up until 2015 in report

Up-scaling and implementation
Focus in cultivation methods and market development
Salt tolerant potatoes in Pakistan

-The Salt Solution Project-
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
