Water is one of the most important production factors to keep up with growing food demand. Making the right decisions in the water-soil-crop nexus is crucial for resilient and sustainable agriculture. Fixeau is a data-to-decision platform for water users worldwide, developed together with water users. We show you how to reduce input costs and improve profitability while taking care of our water-soil resources in a sustainable way. We take decision-support to the next level: we developed a hybrid solution that combines conceptual physical models with Ai algorithms. We understand the complexity in the interaction between soil-water-crop and we can transform this into easy-to-understand decision-support on water management from farmer to catchment scale, enabling collaborative monitoring worldwide.
