"Liquid Land is co-authored with my father Rustam Effendi, a dissident scientist and entomologist who devoted his life to studying, hunting and collecting over 90,000 butterflies in the Soviet Union. Inherited by the Azerbaijani State Institute of Zoology after his death in 1991, his vast collection has disintegrated. Alongside thousands of glass boxes filled with butterfly dust, the only remaining visual evidence of his life's work is the fifty photographs of endangered butterflies for a manuscript he never published.Next to my father's dead, but iridescent butterflies, my photographs show life in some of the world's most polluted areas, near Baku, where I was born and grew up. In my mind, the contrasting images gravitate towards each other - as I have to my father. Since working on this book I have gotten to know him much better than when he was alive. Salty Waters is the translation from Persian of the "Ab-sheuran" Peninsula; in and around Baku, its main city, the earth is breathing with petroleum fumes, as oil oozes to the surface, turning it liquid. The Caspian Sea hugs the eagle-beak shaped land, salting its gas-pocked soil.I photograph the barren, liquid land of Absheron - its environmental and urban decay, its people living amidst the chaos of industrial pollution. My father's work was in the fresh mountain air. The butterflies that he hunted since he was a boy are spectacular in their symmetry. Carefully placed on plants, they shine with vibrant colours, yet he had to kill each one of them for a picture, piercing his microscopic pins through them."Born in 1977, Rena Effendi's first job, at the age of 19, was as a translator for the Azerbaijan International Oil Company, a consortium of some of the world's largest oil producers. This gave her financial independence, as the oil industry was the most lucrative employer for educated youth in Baku. Having gained an inside perspective, Effendi directed her gaze outward and began to take photographs in 2001, focussing on the oil industry's effects on ordinary people's lives. This resulted in 2009 in her first monograph Pipe Dreams - A chronicle of lives along the pipeline, which was published in four different languages (English, German, Russian and Spanish). Liquid Land is a beautiful and poetic sequel to this succesful book.Design: MV LevievanderMeer, Amsterdam
