FACT 1: There is a
correlation between high numbers of CAFOs
and a decline in human population in Iowa’s
counties
| |
Explanation: |
|
| |
There are
statistically significant correlations
between:
1) The number of CAFOs in each county
and a human population decrease
therein (Spearman rho=-.32, p=.0015);
and
2) The total number of animal units
within CAFOs in Iowa’s counties, and a
human population decrease therein.
(Spearman rho=-.32, p=.0011).
The Spearman rho is a
nonparametric correlation (based on
ranked data), and is not sensitive to
the presence of outliers or the shape
of the statistical distributions
governing the data.
The magnitude of the correlations of
approximately .3 indicates the
relationships between population
change and the CAFO variables is of
medium strength. The p-values indicate
the level at which the correlations
are statistically significant, with
P<.05 being significant). The level of
statistical significance is very high.

FACT 2: According to DNR data presented to
the Air & Water Quality standing
subcommittee of the House Environmental
Protection Committee, 86% of permit
applicants build their confinements closer
to another residence than their own. |
|
| |
| |
This data is based on all the Master
Matrix applications received by the
DNR since the matrix process was
implemented in March, 2003. |
|
|
|
| |
|
|
| |
CONCLUSION:
There is a need
for legislation which balances the needs of
the CAFO industry with the separation needs
of neighbors, schools, churches, water
sources, and towns.
House
File 873 addresses these needs.
