“…Within the natural sciences, simulation models play a major role in communicating science (17) (45) , particularly if models are used as integrators of knowledge and data. This means that simulation models can be used to highlight what we know and what we do not know, and as such, they can function as boundary tools (13) .…”

“…Simulation models are a powerful tool for integrating this knowledge and providing actionable insights for policy development. By combining data and knowledge from diverse sources, simulation models can help stakeholders to understand the complexity of environmental systems and test policy interventions (17) . In this paper, we aim to explore the potential of simulation models as a tool for supporting policy development, and to highlight some of the important considerations and challenges associated with their use.…”

Land-system change, freshwater use, biodiversity loss, and changes in biogeochemical flows affect the resilience of the Earth system as a whole. Effective communication between scientists and policy makers is critical in addressing these challenges. Simulation models can be used as integrators of knowledge and data, and play a key role in facilitating effective boundary work between science and policy. Key issues identified are the reliability of model outcomes and the acknowledgement of their uncertainty. However, the use of models provides an advantage when analysing scenarios. Integrated catchment models can provide feedback about joint interpretation of the data and conceptual understanding, resulting in the identification of data needs. The difficulties related to improving how science informs policy is one of communication and negotiation at the boundary, and models can assist in the co-production between researchers and decision makers.

“…This model has been widely used to analyse the impact on water quantity and quality caused by land use and farming practices (Gassman et al, 2007). 2 In recent years, Uruguayan authorities and research groups have made significant efforts to implement, calibrate and validate this model for various relevant basins in the country (Mer et al, 2020). 3 Our study capitalises on these endeavours.…”

We integrate a model that simulates biophysical processes in soils and water with spatial and temporal heterogeneity at the basin scale with an economic model of decisions under uncertainty, to simultaneously evaluate the economic and environmental effects of farming practices and land uses that characterise agricultural intensification. The introduction of uncertainty allows the evaluation of economic impacts both due to changes in average profits and in their volatility. Through our model integration, we endogenously tackle the trade‐offs between economic benefits and environmental outcomes, in terms of nutrient levels in water. Results show that a sizable increase in economic benefits from supplemental irrigation comes from lower risk premiums. Medium‐to‐high increments of fertiliser rates in irrigated crops are dominated in terms of economic benefits by low fertiliser rate increments. We find that water quality deteriorates with intensive farming practices. However, the magnitude of the trade‐offs between economic benefits and water quality is mixed and depends on the nutrient and level of risk aversion considered. The ability of our model to quantify and document the mentioned effects is a relevant input to inform the decision‐making process of agricultural and environmental authorities, often characterised by competing and opposing objectives.

“…Infiltration or precipitation parameters are treated as homogeneous within each sub-basin (10) . The Soil & Water Assessment Tool (SWAT) (11) model is one of the most widely adopted semi-distributed models in Uruguay (12)(13)(14)(15)(16)(17) . It can generate precise results in the simulation of precipitation-runoff processes and pollutant delivery and transport.…”

The development of irrigation involves a change in land use and management and has implications for water quality and quantity. It is critical to design conservation practices and best management practices consistent with sustainable agricultural intensification. The objective of this work was to understand and characterize key processes affecting hydrology, nutrient export and transport, and quantify impacts in the San Salvador watershed. For such purpose, the Soil & Water Assessment Tool (SWAT) was implemented, calibrated for water quantity, and water quality was adjusted using soft calibration techniques. The model reproduces water quantity and nutrient balance, and aids in characterizing the nutrient delivery and transport in the watershed. The magnitude of runoff affects the balance of nutrients. In high flows, diffuse sources are more prevalent, while in low flows, point sources and direct livestock manure to the river are more significant. The main outcomes of this work contribute to the design of strategies to achieve sustainable agricultural intensification. It also describes a new modeling tool freely available that could be used in further studies.
