Soap's Ghost Pastures

November 27, 2012 | Categories: London's Industries and Global Environments

British soap makers relied on a growing supply of fats, potash, and pine resin from overseas locations beginning in the eighteenth century. Much like the overseas "ghost acres" of wheat and sugar that augmented Britain's food supply, soap manufacturers relied on tallow from expansive ghost pastures, which spread across much of the world's natural grasslands at various points in the nineteenth century. Palm, coconut and cottonseed oils, which were also imported from around the world, increasingly competed with tallow in soap making, but they appear to have transformed significantly fewer acres of land when compared to the massive scale of cattle and sheep farming. In researching the global supply-chains of London's soap industry for a recent conference paper and future journal article, I've become particularly interested in the changing geography of Britain's tallow imports.

The graph above demonstrates that the majority of Britain's tallow imports came from Russia during the early nineteenth century. While the Argentine Republic and Uruguay became significant exporters, they did not challenged Russia's dominance during the first half of the century.

This basic pattern continued through to the 1860s, when the "cattle boom" in the United States and growing tallow imports from South America and Australasia drove down the price of tallow, leading to the collapse of Russian exports to Britain.

Did this region shift to wheat and other grains with the collapse of tallow exports? Were there factors beyond price competition that led to the collapse (increased grain cultivation, a cold winter or a drought)? I'm looking forward to reading David Moon's forthcoming book on the topic: The Plough that Broke the Steppes.

I am also doing further research to better understand the boom and bust cycles in tallow exports from the United States and Australasia during the late nineteenth and early twentieth centuries. The American cycle, not surprisingly, coincides with the "cattle boom" and ecological factors played a major role. I expect the same might be true in the Australian case. New Zealand, interestingly, is the only major tallow supplier to grow steadily without a bust through to 1904. I imagine I just need to continue the data entry for another decade or two and I might find a period of crisis for New Zealand.
