CITY ALLOTMENTS MATCH FARM PRODUCTIVITY
A citizen science project by the University of Sussex has found that urban growers in Brighton and Hove were able to harvest 1kg of insect-pollinated fruit and vegetables per one metre square, which is within the range of conventional farming.
The researchers calculated that an average of £380 worth of produce per grower was thanks to insect pollination, with berries being the most attractive crop to pollinators. Over the two-year period, the volunteers recorded more than 2000 pollinating insects visiting their crops. Bees were the most common group of pollinating visitors, accounting for 43% of all flower visits. Surprisingly, flies were also important visitors, accounting for 34% of insect visits.
The urban growers also used fewer pesticides in comparison to conventional farming. The most common…
