【 摘 要 】

Sidoarjo Regency is one of buffer zones of Surabaya City in which directly adjacent with Surabaya at the south part of it. The highly economic growth of Surabaya has many direct y for Sidoarjo regency, mainly due to population growth and urban sprawl that bring negative impacts on sustainability. Decreasing of the productivity because of conversion of agricultural land into settlements and air pollution are major issues that occur in Sidoarjo regency. Regional development should be in line by efforts to conserve the environment so that take environmental carrying capacity into account is a must. Ecological footprint is one of approaches in the calculation of sustainability by identifying the components of consumption and emissions resulting from human activities for subsequent comparison with the availability of natural resources (biocapacity). Biocapacity consists of components of land productivity, ie agricultural land, forestry land, terrestrial fisheries, and constructed land that is processed using satellite imagery as resource. The difference between the ecological footprint calculation and the biocapacity indicates the sustainability of the Sidoarjo Regency. In conclusion, Sidoarjo regency has experienced ecological deficit level 1 with biocapacity value of 25,665 and ecological footprint value of 111,962. It is resulted that natural resources in Sidoarjo Regency are only able to accommodate approximately one-fourth of total consumption in Sidoarjo regency. This prediction could be used as consideration on spatial planning as well as spatial policies in terms of sustainability.
