Assessing the impact of agro-climatic factors and farm characteristics on the yield variation of the Norwegian fruit sector

Tibor Marton


Main drivers of ag. yields:


R&D (new hybrids etc.)



Common sense and anecdotal observations (remember the Tromsø presentation) revealed extreme events tended to impact wide geographic areas

This was called the «systemic» nature of agriculture


No semi-aggregation  farm-level

Not the boring corn, maize, wheat  fruits

No OLS-like Pearson correlation or functional form approach for conditioning spatial correlations on weather  SDM

Finally, if we are smart enough to set the explanatory proxies in a meaningful way presumably we can make the distinction between the effects of, say draught and extreme heat.

And much more in policy relevance
