The Potential for Abandoned Paddy Fields to Reduce Pollution Loads from Households in Suburban Tokyo

The Potential for Abandoned Paddy Fields to Reduce Pollution Loads from Households in Suburban Tokyo

Similar to other Asian nations, suburban areas in Japan are characterized by dense intermixtures of residential areas and farmlands. These hybrid rural/urban areas are evaluated negatively in modern planning frameworks. However, mixed rural/urban landscapes may prove advantageous when attempting to...

These hybrid rural/urban areas are evaluated negatively in modern planning frameworks. However, mixed rural/urban landscapes may prove advantageous when attempting to reconstruct sustainable wastewater treatment systems. This research examines the potential for abandoned paddy fields to reduce nitrogen (T-N) and phosphorous (T-P) loads, an increasingly problematic source of eutrophication in many closed water areas, from households in suburban areas. Our results indicate that abandoned paddy fields remaining in mixed urban/rural areas have significant potential to reduce both nitrogen and phosphorous loads. Accordingly, we suggest that abandoned paddy fields can play an important role in reducing pollution loads in mixed urban/rural areas. http://www.mdpi.com/2073-4441/2/3/649/domestic wastewater pollutionabandoned paddy fieldwetland wastewater treatmentmixed urban-rural land use
