We talked about sustainability of allotments recently, when the argument was made by an expert that the ecological footprint of allotments is terrible. No large-scale economies and all that toing and froing to the plot. And not a word about health and other benefits. I remember that we disagreed vigorously and with good reason.
Who is doing this survey, on whose behalf and to what end? They are asking for quite a commitment in the first place, but how will the result be interpreted? What if it turns out that it is more 'sustainable' to go to Sainsburys? By whatever reckoning!
Allotments are under threat and there is a large demand for new houses. Call me a cynic if you like, but if there is even a slight chance that the result could be spun against keeping and providing allotments in the future, it would be tragic if gardeners had helped achieve that.
Maybe we should ask and know more before participating in good faith.
