Those that happened in the USSR and China, no? After the start of electrification and active mechanization of agriculture, more peasants died of hunger there than in the previous 100 years (in Russia more than in the previous 200 years).
That is simply how socialism works. Land as a mean of production is no different from a factory, so naturally, the products created on the land belong not to the peasants (Petite Bourgeoisie), but to society as a whole.
And guess what this bourgeoisie did when they found out that the grain they produced would now become common property (they sharply reduced the amount they producing).
