But, mismanagement, corruption, and general hostility to the Derg's violent rule, coupled with the draining effects of constant warfare with the separatist guerrilla movements in Tigray, led to a drastic fall in general productivity of food and cash crops. In October 1978, the Derg announced the National Revolutionary Development Campaign to mobilize human and material resources to transform the economy, which led to a Ten-Year Plan (1984/85-1993/94) to expand agricultural and industrial output, forecasting a 6.5% growth in GDP and a 3.6% rise in per capita income. Instead, per capita income declined 0.8% over this period.
