Resource Management Act and Environmental Research Perspectives of the Use of Soil-Plant Systems to Manage the Environment (original) (raw)

Abstract

From the regional councils' perspective the Resource Management Act (RMA) provides greater regulatory control over water quality and quantity management. Air and soil quality management is based on contaminant discharges. The regional councils can also manage land for the purpose of soil conservation. Despite the relative significance to water management, soil-plant systems continue to play a major role in environmental management in New Zealand. Coupled with cultural needs and relatively higher assimilative capacity, soil-plant systems have led to land being the preferred discharge medium over water. Despite their relatively limited treatment capacity, constructed wetlands are also preferred over direct discharges to water. Market access for food products, climatic and soil conditions, land value and sensitive groundwater aquifers are important limiting factors. Soil-plant systems are also vital in mitigating against non-point source discharges. Riparian strips are known to min...
