Khmer population. Pol Pot initiated a series of major irrigation projects across the country. In the Eastern Zone, for instance, a huge dam was built. Many of these irrigation projects failed due to a lack of technical expertise on the part of the workers. The Standing Committee agreed to link several villages in a single co-operative of 500 to 1000 families, with the goal of later forming commune-sized units twice that size. Communal kitchens were also introduced so that all members of a commune ate together rather than in their individual homes. Foraging or hunting for additional food was prohibited, regarded as individualistic behaviour. From the summer of 1976, the government ordered that children over the age of seven would live not with their parents but communally with Khmer Rouge instructors. The co-operatives produced less food than the government believed, in part due to a lack of motivation among laborers and the diversion of the strongest workers to irrigation projects. Fearing criticism, many party cadres falsely claimed that they had met the government's food production quota. The government became aware of this, and by the end of 1976 Pol Pot acknowledged food shortages in three quarters of the country. Members of the Khmer Rouge received special privileges not enjoyed by the rest of the population. Party members had better food, with cadres sometimes having access to clandestine brothels. Members of the Central Committee could go to China for medical treatment, and the highest echelons of the party had access to imported luxury products.

Buddhist monks were viewed as social parasites and designated a "special class". Within a year of the Khmer Rouge's victory in the civil war, the country's monks were set to manual labor in the rural co-operatives and irrigation projects. Despite its ideological iconoclasm, many historical monuments were left undamaged by the Khmer Rouge; for Pol Pot's government, like its predecessors, the historic state of Angkor was a key point of reference. Several isolated revolts broke out against Pol Pot's government. The Khmer Rouge Western Zone regional chief Koh Kong and his followers began launching small-scale attacks on government targets along the Thai border. There were also several village rebellions among the Cham. In February 1976, explosions
