Cities2030 Hands-on workshop for food producers – Velika Gorica LAB
Almost every year now, a major issue for fruit producers from the Zagreb County area has been frost which devastates fruit production (up to 100%). Producers do not have adequate tools and knowledge on how to deal with this recurrent issue. Most producers insure their crops to cover their losses.
We’ve supported fruit producers by organising a practical workshop for their capacity building and presented them with novel technology which has the best effects (for our topography) and can help them mitigate the risk of frosts. During the workshop, they could observe all the details of how this technology works, operate the machines, and ask about everything they found important for their production.

In 20th and 21st century population multiplicated, but hunger is on lowest levels ever. Consequently, death rate fell tremendously. How is it possible? Agriculture made such a progress by endless inventions, by trial and error, with no right for failure.
Although Earth and human agriculture can feed all the people, search for new inventions which would improve human lives does not stops. Such search we do in fruit production.
