Trees help farmers manage drought (report)
This review assesses the benefits of native tree species for shelter on the water regime of pasture and crops. It draws on evidence from the UK, Europe and other temperate zones. Before the evidence is presented overviews are given of evapotranspiration, shelterbelt design and crop micro-climate. The evidence in the review suggests that under the right conditions native tree shelterbelts could enable UK crops to use water more efficiently. Shelterbelts can be viewed as an insurance policy. They may not provide yield increases every year, but they can buffer crop production when extreme weather events strike.
