Allerd Stikker, a Dutch former high-ranking businessman, with degrees in chemical engineering (MSc) at Delft Technical University, and theology (MA) at the University of Leeds, has for long worked on the ecological dimensions in business strategy. With one foot in the business and science world, and the other in the world of ecology, philosophy and religion, he manages to build a bridge between these two worlds - both in his original, inspiring view of life, and in the many international projects he initiated and supported, on a.o. clean water and sanitation in developing countries. He is the author of The Transformation Factor (1992, Eng version), Closing the Gap (2002), and Water, the blood of the Earth (2007).
