The human population has been growing at a rate of at least 1.2% annually since 1960, reaching up to 6.4 billion in 2002 and over 7.0 billion in 2012. In Davao City, the annual population growth rate was 3.22% in 1990, 2.41% in 2007, and 2.36% in 2013. The alarming problem we confront today is that the increase in land area for human use does not expand in proportion to population density increase.
This study aims to address the future problems of land and food shortage through the efficient integration of vertical farms on mixed-use multi-storied commercial-residential buildings in Davao City to provide income-generating condominiums and produce organic crops for residents in an urban setting. The result of the computations showed that integrating farms into mixed-use residential-commercial buildings in Davao City is highly feasible. The gross profit is highest using a gross floor area percentage ratio combination of 50:5:20 for residential, commercial, and vertical farm units, respectively. (i.e., 50% of the building's gross floor area should be allotted to residential units, 5% to commercial units, and 20% to farm units).
Moreover, the gross profit and ROI of the 50:5:20 gross floor area ratio also generated the highest, which amounted to Php 1,785,316,198.00B compared to only Php 501,045,100.00M for the typical commercial-residential buildings in five years. This research has mainly focused on the integration of hydroponics, but the inclusion of aquaponic farms in vertical structures can also be further explored.
