 "The Limits of Food Production  - Vertical Farming"

While food demand continues to increase with a growing global population, climate change and soil degradation have made it already difficult to ensure food security in some regions. Hence, producing more food in a more sustainable way constitutes a central agricultural challenge. An alternative for growing crops in the field has emerged in recent years with vertical farming. With LEDs becoming affordable and more efficient, the economics of indoor and vertical farming are redefined. In vertical farms, all growth factors including light, temperature, humidity, CO2 level, ventilation, water and nutrients can be controlled and optimized. Simultaneously, weeds, pests and diseases can be excluded, and the use of water and fertilizer can be drastically reduced. The aim of this conference is to discuss the current state of science in controlled-environment crop growth and vield, and to detemine the limits of food production in vertical farms.

11th Agricultural Science Symposium on October 29, 2020

[Translate to English:] Grafik: ediundsepp

This year, on October 29th, we will be dedicating ourselves to the topic of "Digital Agriculture - Networking and Interaction".

In agricultural sciences, a wide variety of disciplines are combined to form a complex systems science. Forward-looking key technologies are digitization and data and information management. New digital methods help to capture, understand and manage complex systems.

Intelligent "off-road" vehicle controls and robots have long since conquered a significant place in practical agriculture. The merging of the immense data streams in intelligent databases and their evaluation will not only fundamentally change aspects of production technology, but also the perception of agriculture in politics and society.

As part of the one-day symposium here in Weihenstephan, we want to highlight current research topics in this area with a focus on the aspect of networking different technologies.

This year's symposium on Thursday, September 26, 2019, was dedicated to the highly topical topic "Biodiversity in the agricultural landscape: measure - promote - shape".During the one-day symposium here in Weihenstephan, the significance/value of biodiversity, the causes of biodiversity loss and the effects of different practices, measures and new approaches on diversity were highlighted and discussed. One goal was to bridge the apparent differences between agriculture and society and to find a way to live together instead of against each other.

9th Agricultural Science Symposium on September 27, 2018

This year everything revolved around livestock with the theme "Needs of livestock: recognize - understand - act".

Prof. Brem introduced the topic with a review of "Ten thousand years of humans and livestock" and the bridge to today's livestock husbandry. The lecture by Prof. Troxler was devoted in particular to the topic of animal-environment interactions and placed the terms needs, behavior, husbandry systems and animal welfare in a larger context. In her presentation, Prof. Schmicke dealt with the use of biomarkers in livestock practice and showed which metabolic markers are already in use and where the potential and opportunities for future developments lie. Prof. Krieter focused on health monitoring based on animal behavior. He presented various sensor systems that can support livestock owners in their health management by measuring activity and eating behavior. Ms. Trost from the Max Planck Institute in Seewiesen reported on her behavioral research work on songbirds. Here, the behavior of free-flying songbirds in the aviary and in the field was recorded and quantified with the smallest sensors. Dr. Thiess from Pivita AG presented a diagnostic device for the non-invasive measurement of vital signs in horses. In his lecture, Prof. Rigoll gave an insight into the possibilities for recognizing human actions using methods of pattern recognition and machine learning. In the concluding panel discussion with all speakers and the audience, it was shown how much has already been done in animal husbandry in terms of animal welfare, but also how much still needs to be put into research, training practitioners and educating consumers. The event was moderated by Mr. Chmura from Bayerischer Rundfunk.

The abstracts of the lectures with further information can be found in the conference booklet (Tagungsheft).

8th Agricultural Science Symposium on September 21, 2017

This year's agricultural science symposium of the HEZ took place on September 21, 2017 on the "challenge of climate change". Again this year, the response was great with over 130 participants.

Prof. Menzel from the TUM Professorship for Ecoclimatology introduced the topic with a look at past and current weather phenomena as well as observed and predicted consequences of climate change. The subject area was then considered from different perspectives (crop production and plant breeding, animal husbandry, climate protection policy and economy) and options for adaptation, mitigation, setting goals and implementing measures were discussed.

See the Flyer and here (Tagungsband) for more information.

There was a contribution to this in the weekly review “From Agriculture and the Environment”: Opens external link in new windowhttp://br.de/s/33Y2DMS

5th Agricultural Science Symposium on September 25, 2014

Agricultural material cycles

Nutrient management - environmental protection - resource efficiency

Modern agriculture must meet the growing demand for high-quality and safe agricultural products for feeding people and livestock, for recycling in industrial processes and for generating energy. At the same time, it must meet the requirements for protecting the climate and the environment, including water and soil, as well as animal welfare.

This inevitably triggers an abundance of material flows into the environment, some of which are controversially discussed in public. Keywords such as nitrogen, phosphorus, heavy metals, groundwater, greenhouse gases and manure regulations are often heard in this context.

At the 5th Agricultural Science Symposium "Agricultural Material Cycles" this topic was taken up from the perspective of nutrient management, environmental protection and resource efficiency and examined in detail with the help of competent speakers. In addition, poster presentations will provide information on current Weihenstephan research projects in the field of agricultural material cycles.

The symposium took place on Thursday, September 25, 2014.

With 135 registered participants, the lecture hall was full.
