A collection of useful numbers for quantifying the impacts of the human presence on Earth.Land area requirement for dairy production.
LandAgricultureThis quantity is a single measurement of the quantity at a given point in time (2000 – 2012).
| Value: | 10 ± 3 m2 / yr / Mcal | |
| HuID: | 68128 | |
| Relevant Year(s): | 2000 – 2012 | |
| Summary: | The area of land needed per year to produce 1 megacalorie (103 kcal). This area includes land area for animal husbandry and land area for production of animal feed. | |
| Method: | Reported uncertainty is the standard deviation of the quantity given annually-averaged data over the years 2000 — 2010. The reported value was calculated using formal error propagation techniques given the reported uncertainties of the individual datasets. These uncertainties are in moderate agreement with those estimated using Monte Carlo based bootstrapping estimates. | |
