You are getting downvoted, but presumably, in Russia a significant amount of food is being produced in small family farms/gardens called Dacha [1], with a typical size of only 600 m^2 [4].

Since, original sources are all Russian, it's hard to fully verify via secondary sources, but there are claims that (1) as much as 77% of all vegetables and 59% of all meat [2] or (2) as much as 50% of all food [3] produced in Russia is on these farms.
