”Zero Greenhouse Gas Emission in High Productive Agriculture” – the conference program is now official

High productive agriculture is at a crossroad, where the need for change is imminent to avoid the rapidly growing threat of a climate crisis, but how to we proceed and which technologies can help to achieve large reductions in greenhouse gases? The international conference on “Zero Greenhouse Gas Emission in High Productive Agriculture” will shed the light on new innovative possibilities for reducing greenhouse gas emissions in the most effective and sustainable manner. It all takes place 3-5 May 2022 in Hellerup near Copenhagen, and the program has now been finalized.

It is unequivocal that human influence has warmed the atmosphere, ocean and land. Widespread and rapid changes in the atmosphere, ocean, cryosphere, and biosphere have occurred.” So, states the very first lines of the IPCC report on Climate Change 2021.

The need for action and change is more imminent than ever. Since high production agriculture accounts for a large proportion of agricultural greenhouse gas emissions, there is a need for developing new technologies and management systems. This needs a collective global effort to ensure speedy development and implementation of suitable, efficient and safe technologies. There is also a large need to support this development of technologies with efficient and verified monitoring systems to ensure reliability of the technologies being implemented.

And that is precisely the theme of the conference 'Zero Emission Agriculture in High Porductive agriculture' which will be held on 3-5 May 2022 at Tuborg Havnevej 19, 2600 Hellerup.

The program is here

When researchers from all over the world will meet in May, it is with an aim to create an extended overview of potential technologies for efficiently reducing agricultural greenhouse gas emissions. The focus will be on the efficiency to reduce emissions, economic viability as well as sustainability in regards to other aspects such as environment, biodiversity, animal welfare and human health.

Keynote speakers from the USA, New Zealand, Germany, Italy and China, among others, will kick of debates within the conference's seven themes. In other words, there is ample opportunity to take part in the debate on which path agriculture should take in order to achieve climate neutrality. 

Here is the program for all three conference days:
