BoWie

General framework:
The BOWIE project focuses on tackling uncertainties concerning ammonia emissions in naturally ventilated pig and poultry houses with outdoor runs. Specific aspects of organic and welfare-oriented farming, such as lower stocking densities and access to outdoor runs, can influence emissions, but a suitable measurement method is lacking. This project aims to collect data and develop solutions that reduce ammonia emissions, with a focus on practical applicability, especially on organic farms.

Research approach:
BOWIE will start by developing and validating measurement methods for ammonia emissions, exploring two approaches: tracer gas measurements and drone-based sensor technology. After validation, the methods will be applied at real-life farms. In addition, the project will investigate the influence of livestock density and temperature effects on ammonia emissions. Based on dialogue with the sector and stakeholders, BOWIE will select the most promising ammonia-reducing measures for further research. In the second phase of the project, combined measures will be tested in trials with pigs and poultry.

Relevance/Valorisation:
This project offers a scientifically substantiated approach to ammonia reduction and contributes to the resilience of the organic sector, which is under pressure from the nitrogen regulation. The knowledge gathered supports organic and welfare-oriented companies in Flanders by offering data-driven solutions that meet their specific needs. Thanks to co-creation, these solutions are widely supported within the sector and increase the chance of successful implementation. In this way, BOWIE reinforces Flanders' ambitions to further grow organic agriculture in a sustainable and responsible way.
