Map of total nitrogen emissions from Spain according to the EMEP model for the period 1990-2006 (data from EMEP reduced to half-degree cell). A nitrophilous index was calculated using over 750,000 occurrence records of plants that had been indexed at GBIF for the Iberian Peninsula by March, 2009. To construct this index, the annual number […]
By JUSTIN GILLIS4 June 2011 On a warming planet, humanity faces a great challenge in feeding itself at reasonable cost in the coming century, as I explain in Sunday’s paper. An issue I raise only in passing in the article is that agriculture itself is one of the earth’s greatest environmental threats. To put a […]
A nitrophilous index was calculated using over 750,000 occurrence records of plants that had been indexed at GBIF for the Iberian Peninsula by March, 2009. To construct this index, the annual number of records of nitrophilous taxa was obtained for the period 1900-2008. Next, the obtained value was divided by the total number of plant […]
Contact: Maggie Barrettbarrett@american.edu202-885-5951American University (American University) A study published in the journal Global Change Biology finds that while fertilizer has been the dominant source of nitrogen pollution in Caribbean coastal ecosystems for the past 50 years, such pollution is on the decline. But now, sewage-derived nitrogen is increasingly becoming the top source of such pollution […]
Exceedance of critical loads for eutrophication by nitrogen deposition in 2010 under current European legislation (courtesy of CCE, 2008). Nitrogen deposition remains a threat to biodiversity across large areas of Europe (CCE, 2008). This concern is reflected in the incorporation of an indicator for nitrogen deposition under the Streamlining European Biodiversity Indicators 2010 (SEBI, 2010) […]
By Roger Harrabin Environment analyst, BBC News15 April 2011 Air pollution is damaging 60% of Europe’s prime wildlife sites in meadows, forests and heaths, according to a new report. A team of EU scientists said nitrogen emissions from cars, factories and farming was threatening biodiversity. It’s the second report this week warning of the on-going […]
By ROBERT BURNS21 March 2011 OVERTON — Escalating unrest in the Middle East is not only going to continue to drive gasoline and diesel fuel prices up to 2008 levels, but there’s a good chance it will do the same to the costs of fertilizing pastures, according to a Texas AgriLife Research expert. Even if […]
Scatterplot of the greater Central Valley, California calibration data showing the relationship between air quality score and the proportion of nitrophytic lichen abundance at each plot. Abstract: Lichens are highly valued ecological indicators known for their sensitivity to a wide variety of environmental stressors like air quality and climate change. This report summarizes baseline results […]
WASHINGTON (AFP) – Climate change could increase exposure to water-borne diseases originating in oceans, lakes and coastal ecosystems, and the impact could be felt within 10 years, US scientists told a conference in Washington on Saturday. Several studies have shown that shifts brought about by climate change make ocean and freshwater environments more susceptible to […]
5 February 2011 (Agrimoney.com) – World grain stocks, already squeezed, are in danger of tightening further in 2011-12, Yara International has warned, highlighting the poor condition of winter crops and an incomplete rebound in fertilizer sales. The nitrogen giant said that a rise of some 5%, to nearly 2.3bn tonnes, in world grain production was […]
