| Global freshwater assessments have not addressed the linkages among water vapor flows, agricultural food production, and terrestrial ecosystem services. We perform the first bottom-up estimate of continental water vapor flows, subdivided into the major terrestrial biomes, and arrive at a total continental water vapor flow of 70,000 km3/yr (ranging from 56,000 to 84,000 km3/yr). Of this flow, 90% is attributed to forests, including woodlands (40,000 km3/yr), wetlands (1400 km3/yr), grasslands (15,100 km3/yr), and croplands (6800 km3/yr). These terrestrial biomes sustain society with essential welfare-supporting ecosystem services, including food production. By analyzing the freshwater requirements of an increasing demand for food in the year 2025, we... |

| The composite market design is a proposal for a Transferable Discharge Permit (TDP) system which specifically includes agricultural non-point source (NPS) dischargers and addresses both property rights and transaction cost problems. The first step to implementation of a composite market scheme is the estimation of a supply curve for abatement measures in the catchment area. Estimation is performed by combining costs with modeled loss reductions from selected Best Management Practices (BMPs) and then using this information to estimate the supply curve for abatement which in turn can then be used to set permit prices. The Ronnea catchment in southern Sweden is used as a pilot study area for making this type of estimate. Costs for existing measures that... |

| Evaluations of pathogen management options have focussed on assessing relative removal effectiveness as a basis for prioritising alternative management investment decisions. Using a case study of the Myponga catchment, South Australia, this paper presents results of a cost-effectiveness risk analysis of 13 catchment- and treatment-based water quality management alternatives for mitigating Cryptosporidium risk. A range of costs and benefits including set-up and operating costs, farm business costs and benefits, and environmental service benefits are considered in comparing the net cost associated with each management alternative. Considering the broader range of costs and benefits changes the relative cost-effectiveness of water quality management... |
