The increasing conversion of agricultural land, especially rice fields, has become a particular concern for the government considering rice as the staple food of the community. Based on this, the government is striving to minimize land conversion by establishing sustainable food agricultural protection areas (KP2B), as rice fields have the potential to improve farmers' welfare. This study aims to analyze the income from rice farming, the income of rice farming households, and the welfare level of rice farming households in Merbau Mataram District, South Lampung Regency. This research uses a survey method. The research location was deliberately chosen in the Abung Timur District, North Lampung Regency, as one of the districts with the largest rice harvest area in North Lampung Regency and is a KP2B area.
