The Impact of Population Pressure on Agricultural Land towards Food Sufficiency (Case in West Kalimantan Province, Indonesia)

Estimation of food sufficiency is important as food is one of the people's primary needs. West Kalimantan Province has a large area of agricultural land use so that it is relevant to find out whether the need for food is fulfilled. The relationship between the physical and social environment indicates the appropriate environmental management in certain regions. This research aims (1) to identify the population pressure on certain land carrying capacity and (2) to identify the correlation between land pressure and food sufficiency in West Kalimantan. Institutional data in terms of population, land use, land productivity, and agricultural commodities are analyzed quantitatively. The results show that (1) the land pressure of West Kalimantan is mostly categorized as safe, except for Pontianak City which population presses the most among all cities so that the land carrying capacity is classified as low. It is due to factors of population growth and main activities of certain region that affect the land use and consequently the environment condition; (2) land pressure and food sufficiency in West Kalimantan have negative correlation, which could threaten the food security, so that it is important to consistently implement the food diversification program based on technology-oriented sustainable agricultural approaches. © Published under licence by IOP Publishing Ltd.
