Hedgerows and field margins

Hedgerows and field margins

When I travel across some regions of France, I’m alarmed. Where are the hedges? Where are the field margins? When I travel around the world, if I come across a tea plantation that extends as far as the eye can see without so much as a tree, a hedgerow or a field margin left to nature, I run a mile. I can be sure that I won’t find clean teas there, grown in conditions that respect nature. To produce clean teas without the use of pesticides, you need to work with nature. You need ladybirds to attack other insects, you need birds to eat the insects, you need earthworms to aerate the soil. You sometimes need cows, to mix their manure with green waste to feed the worms and enrich the soil. But all these creatures need somewhere to live. Hedges, trees, field margins, even a cowshed. In my job as a tea researcher, which involves seeking out good quality products grown using clean and sustainable farming methods that respect nature, a field containing a single crop covering hundreds of acres is a nightmare scenario.

Here, in Poobong (India), is a landscape that offers hope for biodiversity.
