Modelling nitrogen use efficiency by world poultry production systems in 2050
Poultry production is highly efficient in terms of nitrogen retrieval among livestock species. Nevertheless, more than 60% of nitrogen feed to animals is lost, mostly as manure. The evolution of these production systems in future is uncertain and will be strongly...
Indoor breeding or full-grazing dairy management? A farm system analysis of Nitrogen Use Efficiency
This paper investigates nitrogen (N) balance and nitrogen use efficiency (NUE) as a function of grazing intensity on dairy farms in Northwest Germany. 30 farms were analyzed in four groups according to their pasture management systems. Based on the farm data, a...
Guidance Document on NUE indicators of the global project INMS
The Guidance Document on NUE indicators has been written in the context of the global project INMS. The Guidance Document, signed by 46 specialists from 19 countries, comprises six sections and 18 chapters covering those aspects considered critical to review,...
A simple and easy-to-communicate framework for analyzing Nitrogen Use Efficiency (NUE) in agriculture and food systems
We developed an easy-to-use framework for nitrogen use efficiency (NUE), applicable to agriculture and food production–consumption systems. We give examples of application, identify potential pitfalls and provide some perspectives on future best management practices...
Nitrogen indicators for characterizing farm performance in European case studies
Nitrogen (N) indicators such as N use efficiency, N surplus and N output based on farm-gate balances are key for evaluating farm performance. In this study, a common protocol was used for calculating N indicators of 1240 farms from six European countries. The goal was...
Indian food nitrogen footprint towards 2050: Religious dietary perspective
Nitrogen (N) inputs required for food production are predominantly lost to the environment prior to being consumed due to religion-influenced food and dietary patterns. We estimated the food N footprint in India considering religious dietary variations during...
The Nitrogen Footprint for INI2020
Global scientific conferences bring together scientists from all over the world. The related travel activities, the facilities of the venue, and the catering influence the environmental footprint of such events. With our work, we present the environmental footprint,...
The nitrogen footprint of Denmark – Applying Danish virtual nitrogen factors to estimate losses from food production
In the past century, human activity has reshaped the global nitrogen (N) cycle, so that the anthropogenic changes to the N cycle have already crossed the safe operating space for the stability of earth system processes. This paper presents the preliminary results of...
Campus Nitrogen Footprints: How Institutions can Manage Their Impact
Under the framework of the nitrogen footprint tool (NFT) network, campuses of higher education institutions have worked collectively to calculate, assess, and manage the nitrogen footprints associated with their activities: these footprints consist of all forms of...
Environmental footprint family to address local to planetary sustainability and deliver on the SDGs
The number of publications on environmental footprint indicators has been growing rapidly, but with limited efforts to integrate different footprints into a coherent framework. Such integration is important for comprehensive understanding of environmental issues,...
