The Politburo was kept in the dark about how bad the famine was getting:

Excerpt from the protocol number of the meeting of the Political Bureau of the Central Committee of the All-Union Communist party (Bolsheviks) “Regarding Measures to Prevent Failure to Sow in Ukraine, March 16th, 1932.

The Political Bureau believes that shortage of seed grain in Ukraine is many times worse than what was described in comrade Kosior’s telegram; therefore, the Political Bureau recommends the Central Committee of the Communist party of Ukraine to take all measures within its reach to prevent the threat of failing to sow [field crops] in Ukraine.

Signed: Secretary of the Central Committee – J. STALIN

Letter to Joseph Stalin from Stanislaw Kosior, 1st secretary of the Central Committee of the Communist Party of Ukraine regarding the course and the perspectives of the sowing campaign in Ukraine, April 26th, 1932.

There are also isolated cases of starvation, and even whole villages [starving]; however, this is only the result of bungling on the local level, deviations [from the party line], especially in regard of kolkhozes. All rumours about “famine” in Ukraine must be unconditionally rejected. The crucial help that was provided for Ukraine will give us the opportunity to eradicate all such outbreaks [of starvation].

Letter from Joseph Stalin to Stanislaw Kosior, 1st secretary of the Central Committee of the Communist Party of Ukraine, April 26th, 1932.

Comrade Kosior!

You must read attached summaries. Judging by this information, it looks like the Soviet authority has ceased to exist in some areas of the Ukrainian Soviet Socialist Republic. Can this be true? Is the situation invillages in Ukraine this bad? Where are the operatives of the OGPU [Joint Main Political Directorate], what are they doing?

Could you verify this information and inform the Central Committee of the All-Union Communist party about taken measures.

Sincerely, J. Stalin

Further, quotas were lowered once the Politburo became aware of the extent of famine:

The low 1932 harvest worsened severe food shortages already widespread in the Soviet Union at least since 1931 and, despite sharply reduced grain exports, made famine likely if not inevitable in 1933.

The official 1932 figures do not unambiguously support the genocide interpretation… the 1932 grain procurement quota, and the amount of grain actually collected, were both much smaller than those of any other year in the 1930s. The Central Committee lowered the planned procurement quota in a 6 May 1932 decree… [which] actually reduced the procurement plan 30 percent. Subsequent decrees also reduced the procurement quotas for most other agricultural products…

Proponents of the genocide argument, however, have minimized or even misconstrued this decree. Mace, for example, describes it as “largely bogus” and ignores not only the extent to which it lowered the procurement quotas but also the fact that even the lowered plan was not fulfilled. Conquest does not mention the decree’s reduction of procurement quotas and asserts Ukrainian officials’ appeals led to the reduction of the Ukrainian grain procurement quota at the Third All-Ukraine Party Conference in July 1932. In fact that conference confirmed the quota set in the 6 May Decree.

There was no intentional famine.
