The objectives of this study are (1) to determine the availability of food, income and food purchasing power of the residents of the City of Mataram and (2) To estimate the availability and area of minimum agricultural land for food in the City of Mataram. The research was conducted by survey method, and primary data collection was carried out by structured interviews using a list of questions, while secondary data collection was carried out by recording or copying from secondary sources at the relevant agencies. Data analysis was performed using functional equations with income constraints aided by SPSS software. The results showed that there was enough available food in the city of Mataram sourced from local production and sourced from food supply outside the city of Mataram, respectively. Amounted to 44% and 56% of the total rice food needs of 45,375 tons/year in 2013. Rice food expenditure is relatively small, which is between around 1.67% of the total income per capita of the population of Mataram City of Rp 5,880,000 / capita/year, so that in terms of access to rice food is relatively easy and inexpensive. The land for food continues to decrease due to land conversion from agriculture to non-agriculture use with a range of 4% per year. Without controlling the land conversion, it is projected that Mataram city is going to be rare in land for food within 25 years. To support regional food security in the city of Mataram city needs at least 453 to 569 hectares to produce the food sustainably, assuming a constant population.
