 Nangka was a thriving agricultural hub before it yielded to urban incursion; it was a primary source for root crops, vegetables, and rice.Conversion of farms into housing patches and the rise of commercial establishments eventually transformed the place into a population center and economic hub.Before 1880, Parang, a sprawling estate of forest, farm, plains and low-lying regions, was part of Barrio Bayan-Bayanan.
