Concluding remarks: limitations to this work…<br />
• Incomplete <strong>and</strong> still evolving scientific knowledge of the interaction of<br />
agriculture with the environment<br />
• Uncertainty regarding the precision or accuracy of indicator model estimates<br />
Limitations concerning the scope of agricultural practices captured by<br />
indicator models (reliability is unknown, uncertainty not quantified)<br />
• Data availability poses constraints in modeling<br />
Scaling Issues – Indicators based on models validated at field scale; scaling<br />
to National, Provincial <strong>and</strong> Regional levels subject to some uncertainty<br />
• Inconsistency between the spatial basis of indicator models <strong>and</strong> economic<br />
models, which currently precludes setting environmental targets at subprovincial<br />
levels.
