Phytomanagement, land-disposal of effluent, and bioenergy production, is site specific due to the plethora of environmental variables that affect plant growth and contaminant mobility. Most contaminated sites contain a heterogeneous mixture of several contaminants. Climatic variables and soil properties may reduce plant growth. The commercial success of phytomanagement is dependent on convincing decision makers that this technology can satisfy environmental regulations. Obviously, field demonstrations at each site are not practical. We therefore developed the Phytoremediation Decision Support System (Phyto-DSS) that calculates the environmental effects of phytomanagement as well as its costs, compared to other technologies or inaction.
The Phyto-DSS is a “whole system”-type model that calculates plant growth, water flux, component (e.g. contaminant or nutrients) flux, and costs & income over large vegetated areas. These simulations reveal the feasibility, risk, and potential outcomes of phytomanagement. The system requires daily climate data, as well as data on the substrate and the plants. The Phyto-DSS makes an economic assessment by comparing the costs of phytoremediation with those of inaction, and the best alternative technology.
The Phyto-DSS was created in 2000 at the, Instituto de Recursos Naturales y Agrobiología de Sevilla, Spain during an OECD fellowship. Subsequently, the Phyto-DSS was developed at HortResearch, Palmerston North, New Zealand (2001 - 2004), and the Swiss Federal Institute of Technology, Zurch, Switzerland (2005 – 2007).
