A photographic impression of the gradual changes in two ecosystem types

Year: 2009 Author: Hugo Ahlenius, UNEP/GRID-Arendal
Description:
Globally, over 1,000 (87%) of a total of 1,226 threatened bird species are impacted by agriculture. More than 70 species are affected by agricultural pollution, 27 of them seriously. Europe’s farmland birds have declined by 48% in the past 26 years (European Bird Census Council, 2008). Pesticides and herbicides pose a threat to 37 threatened bird species globally (BirdLife, 2008), in addition to deleterious effects of agricultural chemicals on ground water.
