Fixing nitrogen: the challenge for climate, nature and health
This report from the UK charity the Soil Association examines how disruption to the nitrogen cycle can damage the climate, biodiversity and human health. It proposes replacing widespread use of synthetic fertilisers with agroecological use of nitrogen-fixing legumes and manure from grass-fed livestock.
Europe is the world's second-smallest continent by surface area, covering just over 10 million square kilometres or 6.8% of the global land area, but it is the third-most populous continent after Asia and Africa, with a population of around 740 million people or about 11% of the world's population. Its climate is heavily affected by warm Atlantic currents that temper winters and summers on much of the continent. In the European Union, farmers represent only 4.7% of the working population, yet manage nearly half of its land area.
