The world is facing a fertiliser crisis, with far too little in some places, and far too much in others, a new report from the United Nations says today.
The mass application of nitrogen, phosphorus and other nutrients needed for plant growth has had huge benefits for world food and energy production, but it has also caused a web of water and air pollution that is damaging human health, causing toxic algal blooms, killing fish, threatening sensitive ecosystems and contributing to climate change, says the report, “Our Nutrient World”.
However, in some parts of the world, insufficient access to fertilisers remains the problem, and still hampers food production and contributes to land degradation – even while supplies of some nutrients such as phosphorus are more and more seen to be limited.
The report calls for a major global rethink in how fertilisers are used across the world, so that more food and energy can be produced while pollution is lessened rather than increased.
