Interpretive Summary: The Soil and Water Assessment Tool (SWAT) is a computer based model used throughout the world to examine watershed scale processes. This Special Issue of Agricultural Water Management is part one of a series of publications describing application and modification of the SWAT model. The issue includes 8 papers that cover several topics: eco-hydrological and environmental impacts of biofuel production, irrigation efficiency, impacts of climate change, influence of improved datasets for better representation of management and conservation practices, calibration strategies and model modifications for better estimation of plant available water, and model modifications for improved nutrient transport simulation. This introduction provides an overview of these research papers.

Technical Abstract: Global change and demographic changes increasingly cause water, food, and health problems in many areas of the world. In addition, the growth in bioenergy production leads to land-use change and associated environmental impacts. The lack of integration in resource assessments and policy-making leads to inconsistent strategies and inefficient use of resources. However, integrated assessment is achievable thanks to the availability of highly adaptable and configurable tools. One such tool for integrated assessment is the Soil and Water Assessment Tool (SWAT). This Special Issue of Agricultural Water Management is part one of a series of publications describing application and modification of the SWAT model. The issue includes 8 papers that cover several topics: eco-hydrological and environmental impacts of biofuel production, irrigation efficiency, impacts of climate change, influence of improved datasets for better representation of management and conservation practices, calibration strategies and model modifications for better estimation of plant available water, and model modifications for improved nutrient transport simulation. This introduction provides an overview of these research papers.
