Abstract

Urban agriculture potential is examined in three suburbs of increasing density in Auckland, NZ. A review of the relationship between urban indicators (net density and housing patterns) and potential solar energy available at ground level is done. Since soils are generally fertile and water readily available solar access to ground level becomes an indicator of productivity. Using the subtraction method and satellite photography from Auckland council GIS viewer, potentially productive land is estimated in three residential blocks-Mt Eden, Sandrigham and New Lynn. Based on the results the food energy potential of each site is determined. Preliminary results indicate that low density New Lynn has the highest potential for sustainability with surplus food energy. Medium density Sandrigham could meet 50 per cent of its vegetable dietary requirement while high density Mt Eden is unsustainable in UA. Recommendations are suggested as to how UA maybe integrated in urban growth strategies.
