Warfare’s ecological footprint: A Synthetic Control approach with data from the Falkland Islands
Assistant Professor at CEE-M (University of Montpellier)
Warfare has been found to have detrimental impacts on biodiversity due to its long-lasting economic and social consequences. Yet, much less is known about the amount of biodiversity loss directly resulting from the use of military technology. This paper analyzes the environmental consequences of one of the largest aerial and naval conflict of the late 20st century, namely the 1982 Falklands War. The fact that the conflict was unrelated to environmental issues, did not spill over to neighboring countries, and did not relapse afterwards, allows us to circumvent identification issues that commonly affect comparative studies on the ecological footprint of warfare. As an indicator of the marine ecosystem status, we analyze population trends of king penguins breeding on the Falkland Islands and six other Sub-Antarctic colonies over a thirty-year period (1965-1995). We use the Synthetic Control method – a method that was explicitly designed for small-N comparative studies – in order to build “counterfactual” Falkland Islands whose characteristics closely resemble those of the Falklands before the war and allows us to approximate the trends of the outcome variable in the absence of the war. Results indicate that the war has led to a substantial decrease of king penguins’ breeding population on the Falklands: by the mid-1990s, the number of breeding pairs on the islands would have been at least twice as high in the absence of the war.
