Science-based solutions, applied in the field
​
Based in the Netherlands, with over 20 years of experience in saline agriculture. From a one-hectare trial on Texel to projects across the world — and back again.
​
From salinity assessments and salt-tolerant crops to hydroponics, from field training to scalable solutions – we help farmers adapt to salinity with practical, science-based approaches.
Soil and water salinity threaten farmer livelihoods and global food security.
According to FAO (2024), 1381 million hectares of land – 10.7% of the global land area – are salt-affected. At the same time, UN-Water (2021) reports that around 2 billion people live in water-stressed areas.
