Harnessing the power of nature using 70 years of research

Over half a century, Dr. Haller wrote hundreds of papers based on his innovations, experiments and research. From addressing land degradation to analysing community behaviours, the scope of his work is vast. We have gathered all of his knowledge – as well as papers written by the many students who have studied our work

We believe in sharing best practice and good ideas. Before the Internet, we did this by publishing our research in newspapers and making films. Now the science that guides everything we do can be accessed for free anytime, by anyone.

All of the techniques that Haller uses, have been developed from scientific research conducted as part of PHD programmes and masters programmes by students from all over the world. Some of their papers are published here.
