Based on the understanding that – in the light of climate change, rapidly dwindling biodiversity as well as an overall downgrade of the ecosphere incuding air, water, and soil – an “ecological turnaround” is essential and urgent, Andreas J. Hirsch researched and wrote about the work of inspiring pioneers in the field of ecology.
In 2011 he published the book Hundertwasser – The Art of the Green Path (Prestel / Random House, Munich, 2011) about the work of the Austrian artist and ecological pioneer Friedensreich Hundertwasser (1928–2000), together with curating an exhibition of the same title for the 20th anniversary of KUNST HAUS WIEN.
In 2016 he wrote the book Soil Lives! The Live and Work of Annie Francé-Harrar (1886–1971), an ecologial pioneer and early warner about about ecological desasters.
Together with the painter Alexandra Uccusic, he has since 2009 been collaborating in a biodiversity project for creating and documenting a habitat for sand lizards and other species in Vienna.
