Konstantin Yanev is the main person responsible for the Organic Gardens Oreshak, part of the Culinary Art Institute in Varna, North-Eastern Bulgaria. He admits that when he first started his garden, the farming practices he was applying were conventional, not ecological. The more he learned however about the different interactions and processes that occur in the ecosystem, the more he started considering what other cultivation methods are available, which do not deplete the natural environment but actually support and restore it.
The ecological gardens in Oreshak are now a representation of what biodiversity and balance in a farm look like. The variety of crops and their cultivars is astonishing – there are 50 different varieties of tomatoes, 15 different varieties of basil and those are just a few of the examples as the farm maintains its own seed bank.

Greenpeace went to document ecological farming practices in the ecological gardens Oreshak and also organised an open farm event to introduce more people to the benefits of ecological farming.
