Agroecosystems on the American Frontier: Material and Energy Systems and Sustainability Fridolin Krausmann Institute of Social Ecology Klagenfurt University Austria fridolin.krausmann@uni-klu.ac.at Geoff Cunfer Department of History University of Saskatchewan Canada geoff.cunfer@usask.ca
2
US immigration Cereal exports
3
George Thir and Elizabeth Demmer migration from Austria-Hungary to Kansas, 1880s Gols, Zurndorf, Ragendorf, Kaltenstein homestead in Decatur County, 1884 built a family, a farm, and an agro-ecosystem, 1885-1940
4
Q. How did the farm system that the Thirs left behind compare with that which they found (and created) on the Great Plains frontier? Comparative case studies: Theyern, Austria, 1829 Finley Township, Decatur County, Kansas, 1885-1940 Social metabolism approach Key socio-ecological indicators
5
Metabolic relationships in agricultural production systems Agroecosystem Woodland Grassland Cropland Local socio-ecological system Production Livestock Farmsteads and infrastrcture Machines and tools Population Human population with certain characteristics: Age structure Fertility Mortality … Work / migrationImport / export Material / energy Work Draft power Manure Food Biomass Energy
6
Village farm settlement, Theyern, Lower Austria, 2002
7
Franciscean Cadastre, Theyern, Austria, 1829 land use & land cover map land ownership textual description of farm system and productivity quantitative data yields livestock demography taxes
8
Theyern land use, 1829 Area: 225 ha Population: 102 Farms: 17
9
Theyern 3-field rotation & dispersed fields, 1829
10
Consolidated farms Finley Township Decatur County Kansas 1921
11
Rural farm settlement in Finley Township, 2004
12
Census Manuscripts, Kansas, 1885-1940 9 snapshots of farm and family Land use crop acreage & production livestock fencing, irrigation, tractors Demography name, age, sex, literacy birthplace, parents’ birthplace, mother tongue Nested scales farm township county
13
Key socio-ecological indicators People and Space population density land availability Farm Productivity grain yield area productivity labor productivity marketable crop production Livestock and Nutrient Management livestock density nitrogen return
14
Theyern: land was scarce, but labor was abundant. Finley Township: labor was scarce and land was abundant People and Space: Population Density
15
Theyern: shortage of arable land Finley Township: shortage of labor to work the land People and Space: Land Availability
16
Theyern: considerable yields, rising through 19th century Finley Township: very high yields, falling sharply Farm Productivity: Grain Yield
17
Similar area productivity in Theyern and Finley Township. Large fluctuations in Kansas due to variable rainfall. Farm Productivity: Area Productivity
18
Theyern: 1 laborer fed 2.5 people Finley Township: 1 laborer fed 100 people (1930) Farm Productivity: Labor Productivity
19
Finley Township’s excess production was exported to urban, industrializing parts of the eastern US, UK, & western Europe. Farm Productivity: Marketable Crop Production
20
Theyern: multi-use animals—food, waste recycling, power, manure Finley: specialized animals—power (horses), grazing (cattle) Livestock & Nutrient Management: Livestock Density
21
Theyern: near 100% N return, using livestock manure Finley Township: 20-40% N return: soil mining Livestock & Nutrient Management: Nitrogen Return
22
Austria Kansas Long term trends in grain yield: Austria and Kansas, 1830-1940 Austria: Yield increases: optimization of low input farming Kansas: Declining yields: stock depletion; large fluctuations
23
Conclusions Resource efficiencies Theyern: labor abundance for long-term subsistence (risk minimization) Finley Township: fertile land abundance for market production (improved standards of living) Both efficient in own way 19 th century trajectories Theyern: increasing yields Finley Township: declining yields (soil crisis by 1930s) 20 th century convergence: replacing soil with oil fossil fuels solved soil crisis in Kansas yields skyrocketed in both places by 2000
