Among other things (since you want to take a 100% Keynesian view), the government created sticky nominal wages and prices (with minimum wages and price floors). Hey, remember why Keynesian economics claims we need to print money?

Loose monetary policy during a drought is not just supported by Keynesians (who really emphasize more expansionary fiscal policy), and is definitely not a 100% Keynesian view. Monetarists, for instance, support it widely. As do other economists. Friedman supported it, as does Bernanke, Greenspan, Summers, Mankiw, et al. To claim that an expansionary monetary policy is 100% Keynesian is just absurd and distorts the positions of other economists.
Lastly, if you read your own link (to the Wikipedia article on causes of the GD), you'll discover that there are many proposed explanations (including, for example, protectionism).
That's it for me.
