**Abstract**

Increasing food crop production remains a top priority for the Indonesian government, as demand increases as the population grows. One of the obstacles faced in increasing production is climate change. One of the adaptations to climate change in agriculture is to establish policies for the development and modification of infrastructure that can save water resources management and establish institutions involved in the planning and implementation of water resources management. Kendal Regency, Central Java Province, is one of the regions that contributes to food availability in Indonesia. These conditions support the development of food crops, especially rice, corn, and soybeans. Since 2015, the government and farmers have made improvements to the tertiary irrigation network in paddy fields. This activity aims to increase the cropping index and achieve cropping patterns for one year. In the implementation of irrigation network improvement activities, the community of farmers using water usually works together in determining the location for repairs and making suggestions for improvements to the government. Improvements to irrigation networks were able to increase the cropping index by 0.37 from 1.85 in 2015 to 2.22 in 2016 or equivalent to an area of 8,880 ha (standard area ±24,000 ha).
