RAS & Aquaponics

Since 2010 I have been working with both fresh- and saltwater aquaponics and related plants as a potential circular aquaculture business model. I have been an advisor for FAO, Food & Agricultural Ministries, The Danish development agency ‘Danida’ as well as Technical Universities delivering research and national action plans promoting aquaponics and related youth ‘agripreneurs’. These achievements are based on long term R&D within the field of commercial oriented aquaponics focusing among others on:

– Optimal biomass relations between fish & plants

– Environmental synergies from CO2 stripping in fish to increased plant growth

– Fish tanks operating as heat buffers in greenhouses saving energy in the northern hemisphere

– Closing the water cycle in aquaponics

Algae and seaweed are new areas of exploration for expanding circular approaches in aquaculture. PRK has experience working with different algae reactors utilizing fish manure, CO2 stripping and LED lighting producing algae with a high content of Omega-3 fatty acids for fish feed and human consumption. Likewise, PRK is the Danish national representative in the EU cost action program: CA 20106: Tomorrow’s ’wheat of the sea’: Ulva, a model for innovative mariculture running from 2021 to 2025.

Urban farming

When I started to explore the prospects of aquaponics back in 2010, I realized its huge potentials of moving high quality and sustainable food production back into the city. Food production within the cities and around their fringes could in the same time help minimizing transport, reduce packaging and storage and support overall urban policies of climate resilience and food security.

With funding from the EU Eco-innovation and Nordic Marine (2012 and 2013), and a mandate to set up an urban aquaponic roof top farm I discovered the many obstacles and barriers urban farming faced at the time. This goes in regards to its non-integration in overall city planning, zone regulations complicating urban food production and the limited amount of buildings and roofs are actually able to carry a ‘green weight’ of significance.

This led me into the studies of urban food policies, relevant architecture and new city planning approaches needed, if urban farming is to carry its historical legacy of designing sociable cities into the future.

Based on these insights, I published the following book in 2021:

‘500 years of Urban Farming in Denmark – Past Experiences & Future Prospects’ available on Amazon.

Two podcast, derived from the book, have been made.

Development consultancy

My core competences within development work is a deep understanding of the barriers and market failures agri- and aquaculture value chains encounter trying to reach different consumer outlets. I have in this regard, been assigned to support value chains targeting export markets, domestic urban-centered retailers as well as hospitality chains catering for game parks and high-end hotels. Long-term experiences have been acquired in East Africa, Latin America and the MENA region.

I have written extensively about the classical challenges when demand- and market driven approaches are at the focus for value chain development.  Please feel free to download the articles under Publications.

Training & Capacity Building

I have been teaching and lecturing for many years, both at universities, business schools and ATVET (Agricultural Technical Vocational Education and Training). By extension, I have a pedagogical license and certified to teach in English at university level.

These skills have all come in handy in various development jobs as both a team leader as well as being responsible for organizing relevant stakeholder workshops providing training courses and required capacity building. The latter has been within the educational system as well as agricultural ministries.
