Bijna de helft van de Nederlandse dijken is afgekeurd. Ze zijn te zwak om het land te beschermen tegen het stijgende water. Ophogen kan, verstevigen met stenen en beton ook, maar volgens Hans de Kroon zijn bloemen het antwoord. De ecoloog van de Radboud Universiteit onderzoekt nu welke bloemige kruiden de dijken het stevigst maken. Dat doet hij door zelf dijken aan te leggen en door dijken te stresstesten met miljoenen liters water. Wij hebben de beelden. #dijken #bloemen
