On the operational value of weather and climate services for agriculture: a new paper on HESS

We just published a new paper on Hydrology and Earth System Science where we explore the operational value of different long term forecast to support farmer cropping decisions.  Quantifying this value, however, might not be straightforward as better forecast quality does not necessarily imply better decisions by the end users, especially when forecasts do not reach their final users, when providers are not trusted, or when forecasts are not appropriately understood. In this study, we contribute an assessment framework to evaluate the operational value of W&C services for informing agricultural practices by complementing traditional forecast quality assessments with a coupled human–natural system behavioural model which reproduces farmers’ decisions. This allows a more critical assessment of the forecast value mediated by the end users’ perspective, including farmers’ risk attitudes and behavioural factors. The application to an agricultural area in northern Italy shows that the quality of state-of- the-art W&C services is still limited in predicting the weather and the crop yield of the incoming agricultural season, with ECMWF annual products simulated by the IFS/HOPE model resulting in the most skillful product in the study area.  More HERE


A stakeholder meeting has taken place in Lusaka (Zambia) as part of the DAFNE project. We have been meeting with stakeholders from Zambia and Mozambique and developed interactive sessions to explore issues, best practice and pathways to sustainability in the whole Zambezi river basin and the two case studies of the Lunsemfwa and Luia sub-basins.  This is the first step to building the DAFNE Negotiation Simulation Lab which will enable stakeholders and decision maker to explore the multidimensional space of water – energy and food nexus in the Zambezi basin. A field trip in the Lunsemfwa based has taken place after the meeting.

How problem formulations shape trade-offs in water resources systems: a new paper on WRR

Managing water resources systems requires coordinated operation of system infrastructure to mitigate the impacts of hydrologic extremes while balancing conflicting multisectoral demands. Traditionally, recommended management strategies are derived by optimizing system operations under a single problem framing that is assumed to accurately represent the system objectives, tacitly ignoring the myriad of effects that could arise from simplifications and mathematical assumptions made when formulating the problem. In this new paper we illustrate the benefits of a rival framings framework in which analysts instead interrogate multiple competing hypotheses of how complex water management problems should be formulated. We illustrate this on the monsoonal Red River basin in Vietnam by optimizing operations of the system’s four largest reservoirs under several different multiobjective problem framings.  MORE HERE

CHNS Workshop in Tübingen

We are participating in the International Workshop on Innovation in Modelling Coupled Natural and Human Systems Related to Water in Tübingen.  The idea of the workshop is to discuss about water, energy and food nexus modelling advances comparatively analysing experiences from EU, US and developing countries. The target is to come out with a collaborative project proposal to be submitted in the upcoming months. More here
