Showing results for: Fertilizer use
In this paper, the authors present an analysis of the nitrogen cycle in the agricultural production system of 12 world regions. From these results, they go on to suggest improvements in nitrogen use by changing the role of human diet, international trade and local production.
Recent assessments have strongly suggested that meeting the widely agreed target of limiting global warming to less than 2°C will require the deployment of substantial carbon sinks in addition to measures to curb greenhouse gas (GHG) emissions. This perspective article examines the latest research and thinking on the ability of agricultural soil management to reduce GHG emissions and promote soils as carbon sinks, and the practical feasibility of implementing available soil management practices
Biofuel policies have been a major driver of rising prices for biofuel crops around the world, such as rapeseed, corn and soy. In this paper researchers take France as an example and show that a tax of €0.05–0.27 per kg of fertiliser could help to limit French farmers’ use of fertiliser (driven by the high rapeseed prices resulting from biofuels policy).
Nanotechnology – the designing of ultra-small particles – is part of the evolving science of precision agriculture, and could potentially solve some of the world’s most pressing problems at the food-energy-water nexus as it requires fewer natural resources and water, and enhances plant nutritional values.
This paper published in Nature Plants finds that if tropical farming intensifies, major additions of phosphorus to soils will be needed
This study looks into how residential landscapes in Chicago, USA, which constitute the largest single urban land use, benefit ecosystems. It argues that even though we often don’t associate modern urban areas with healthy ecosystems, home gardens in urban landscapes can contribute to important ecosystem services.
In this study, researchers from the Netherlands and Italy investigate the long-term (past and future) changes in phosphorus (P) budgets in grasslands used for grazing and in connection with croplands. The authors recognise a lack in the literature of studies characterising the P cycle in relation to grasslands and croplands, and - as grass-dependent livestock demand is increasing – they seek to address this lack of understanding.
In this policy briefing, Global Justice Now reports on the alleged “hidden emissions” of three major agribusinesses, the aim being to highlight the real contribution that multinational feed, fertiliser and beef agribusinesses make to climate change.
This report by the Food and Agriculture Organisation of the United Nations (FAO) aims to inform decision-making that focuses on reducing impacts on natural capital.
This new report “Planetary Health: Safeguarding Human Health in the Anthropocene Epoch” launched by The Rockefeller Foundation - Lancet Commission argues that changing environmental conditions such as increased carbon dioxide emissions, rampant use of fertilizer and the acidification of the oceans could lead to major health challenges for millions of people. Increasing population, unsustainable consumption and production and the over-exploitation of natural resources are also factors straining the planet's resources and having an impact on human health.
The food and agriculture (F&A) industry must increase production, availability and access to food significantly over the next ten years if it is to meet the demands of a larger, increasingly urban global population according to a new report presented by Rabobank at Expo Milano 2015.
A new study from researchers at The Earth Institute of Colombia University and the Woods Hole Research Center says emissions of nitrous oxide could double by the middle of the century if left unchecked. Nitrous oxide is the third biggest contributor to human-induced climate warming after carbon dioxide and methane.
This paper published in PNAS - Proceedings of the National Academy of Sciences of the United States of America - looks at the environmental costs of food production and in particular livestock based food production. The paper is based on annual 2000–2010 data for land, irrigation water, and fertilizer from the USDA, the Department of the Interior, and the Department of Energy.
