Aanleiding van het project
By combining the latest technological developments in the field of ICT, hydrological models, crop models and satellites, it is possible to develop a real-time forecasting system for crop production, enabling water boards, farmers and the insurance broker to improve their services and possibly reduce costs. .
Therefore, a joint project proposal is made by Achmea (Agro), Deltares and the water boards Aa en Maas and Vechtstromen.
Doel van het project
The general aim of this project is to:
– Set up a real time forecasting crop modelling system that feeds the farmer app with relevant crop production data
– Calibrate the models and test them for practicality
– Test the usability of these data for the pilot farmers and the water boards involved
– Test the usefulness of these data for the determination and tracking of crop damage
Omschrijving van de activiteiten
It is proposed to calculate the available soil moisture and crop production on a parcel basis with the coupled MODFLOW-MetaSWAP-WOFOST model during the 2018 growing season. The pilot area will be determined together with Achmea and the water boards. The suggestion is to take the upstream catchment of the Vecht area of Ommen (towards the German border) and a pilot area in the East of Brabant (water boards Aa en Maas). These areas are preferable because on the one hand there are many clients of Achmea and on the other hand activities carried out by water boards in these areas are carried out within a knowledge program for the high sandy soils (Lumbricus).
The models will be integrated into FEWS for real-time forecast of crop production. the output from FEWS will feed a developed app. The farmers app will be made available to a selection of farmers in the pilot area (15-20).
The project is divided in two stages. In phase 1 we will develop in close calibration with the waterboards, Achmea and the farmers the forecasting system for crop production that will feed the developed app by Milan SAF. Also experience from Wageningen Envrionmental Research in crop modelling (WOFOST) will be involved. In phase 2 we will calibrate the models and do data assimilation with available soil moisture and groundwater level measurements retrieved from satellite data to improve the results of the model. The following steps describe the activities to fulfil the project’s objectives.
Phase 1: Setup the operational system and develop the farmers app (~170K Euro ex BTW)
1. Deltares in collaboration with the waterboards and Achmea will select the most suitable pilot areas with preferably a dense monitoring network of groundwater levels and soil moisture
2. A Wworkshop with farmers farmers will be organised by Deltares, Achmea, waterboards and Milan to about the app andtorefineto refine the app to farmers’ needs.
3. Deltares will clip the regional MODFLOW-METASWAP-WOFOST model for th
The deliverables include:
– Daily updated 10 day forecast data of WOFOST in the required data format will be automatically exported to the farmers app (eg potential production and water-limited production)
– Daily updated 10 day forecast hydrological and WOFOST data in the required data format will be automatically exported to the water board (eg potential production and water-limited production)
– Organizing 2 workshops with farmers, Achmea and waterboardwaterboards:
o 1 workshop: output will be a list of requirements for the app from the farmers
o 1 workshop :output will be an evaluation of the farmers app
o Description of the setup of the operational system
o Description of the applied models (WFlow, MODFLOW, MetaSWAP and WOFOST)
o Description of the calibration and verification of the models
o Descriptions of the outputs of the workshops
o Conclusions and recommendations
Combining the latest technological developments in the field of ICT, hydrological models, crop models and satellites, it is possibleand demonstrate the possibility to develop a real-time forecasting system for crop production, enabling water boards, farmers and the insurance broker to improve their services and possibly reduce costs. .
The Operational system and developed scripts will be available via our website. Publication and presenting the results and tools of this study will be executed by Deltares and consortium partners. Our consortium will try to scale up this activity to a national level and make the farmers app available for all Dutch farmers and water boards. The Dutch Hydrological model in combination with satellite data can be applied for this purpose in combination with WOFOST.
