In achieving this objective, the study served to focus on a number of features that have not previously been highlighted. These include the effect of the size of the area to which slurry is applied, the interaction between solar radiation input and wind speed, the role of the solid chemistry and the interaction between slurry NH4 and the slurry/soil cation exchange capacity (CEC). The most important processes controlling NH3 volatilisation were considered to be turbulent and molecular diffusion in the atmosphere, meteorological processes controlling evaporation and surface temperature, the ion production and buffering processes controlling the pH of the slurry/soil liquid, the solid chemistry that determines precipitation of NH4 to slurry dry matter, the physical processes controlling the movement of slurry liquid into and within the soil, and the interaction of slurry liquid with soil CEC.}, keywords = {EPNB}, author = {Sommer, S.

Here,we quantify the contribution of European livestock production to these major impacts. For each environmental effect, the contribution of livestock is expressed as shares of the emitted compounds and land used, as compared to the whole agricultural sector. The results show that the livestock sector contributes significantly to agricultural environmental impacts. This contribution is78{\%}for terrestrial biodiversity loss,80{\%}for soil acidification and air pollution (ammoniaand nitrogen oxides emissions),81{\%}for global warming, and73{\%}for water pollution (bothNandP). The agriculture sector itself is one of the major contributors to these environmental impacts, ranging between12{\%}for global warming and59{\%}for Nwater quality impact. Significant progress in mitigating these environmental impacts in Europe will only be possible through a combination of technological measures reducing livestock emissions, improved food choices and reduced food waste of European citizens.

Nitrogen (N) is a crucial element for agriculture and human nutrition, but in excess it can cause serious environmental damage. The Sub-Saharan African nation of Tanzania faces a two-sided nitrogen problem: while there is not enough soil nitrogen to produce adequate food, excess nitrogen that escapes into the environment causes a cascade of ecological and human health problems. To identify, quantify, and contribute to solving these problems, this paper presents a nitrogen footprint tool for Tanzania. This nitrogen footprint tool is a concept originally designed for the United States of America (USA) and other developed countries. It uses personal resource consumption data to calculate a per-capita nitrogen footprint. The Tanzania N footprint tool is a version adapted to reflect the low-input, integrated agricultural system of Tanzania. This is reflected by calculating two sets of virtual N factors to describe N losses during food production: one for fertilized farms and one for unfertilized farms. Soil mining factors are also calculated for the first time to address the amount of N removed from the soil to produce food. The average per-capita nitrogen footprint of Tanzania is 10 kg N yr-1. 88{\%} of this footprint is due to food consumption and production, while only 12{\%} of the footprint is due to energy use. Although 91{\%} of farms in Tanzania are unfertilized, the large contribution of fertilized farms to N losses causes unfertilized farms to make up just 83{\%} of the food production N footprint. In a developing country like Tanzania, the main audiences for the N footprint tool are community leaders, planners, and developers who can impact decision-making and use the calculator to plan positive changes for nitrogen sustainability in the developing world.}, keywords = {nitrogen, nitrogen footprint, Sub-Saharan Africa, Tanzania}, issn = {17489326}, doi = {10.1088/1748-9326/aa5c42}, author = {Hutton, M.O. and Leach, Allison M. and Leip, Adrian and Galloway, James N. and Bekunda, M. and Sullivan, C. and Lesschen, J.P.} } @article {Zurek2018, title = {{Assessing Sustainable Food and Nutrition Security of the EU Food System {\textemdash} An Integrated Approach}}, journal = {Sustainability}, volume = {10}, number = {11}, year = {2018}, pages = {4271}, doi = {10.3390/su10114271}, author = {Zurek, Monika and Hebinck, Aniek and Leip, Adrian and Vervoort, Joost and Kuiper, Marijke and Garrone, Maria and Havlik, Petr and Heckelei, Thomas and Hornborg, Sara and Ingram, John and Kuijsten, Anneleen and Shutes, Lindsay and Geleijnse, Johanna M and Terluin, Ida and van{\textquoteright}t Veer, Pieter and Wijnands, Jo and Zimmermann, Andrea and Achterbosch, Thom J. and Havl, Petr} } @article {Vanham2019a, title = {{Environmental footprint family to address local to planetary sustainability and deliver on the SDGs}}, journal = {Science of The Total Environment}, volume = {693}, number = {June}, year = {2019}, month = {jul}, pages = {133642}, publisher = {Elsevier B.V}, abstract = {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, policy formulation and assessment of trade-offs between different environmental concerns. Here, we systematize published footprint studies and define a family of footprints that can be used for the assessment of environmental sustainability. We identify overlaps between different footprints and analyse how they relate to the nine planetary boundaries and visualize the crucial information they provide for local and planetary sustainability. In addition, we assess how the footprint family delivers on measuring progress towards Sustainable Development Goals (SDGs), considering its ability to quantify environmental pressures along the supply chain and relating them to the water-energy-food-ecosystem (WEFE) nexus and ecosystem services. We argue that the footprint family is a flexible framework where particular members can be included or excluded according to the context or area of concern.

Different reactive nitrogen species (NH3, NH4+, NO, NO2, NO3-, and N2O) are set free by a large variety of anthropogenic activities and cause numerous negative impacts on the environment. The complex nature of the nitrogen cycle hampers public awareness of the nitrogen problem. To overcome this issue and to enhance the sensitivity for policy action, we developed a new, impact-based integrated national target for nitrogen (INTN) for Germany. It is based on six impact indicators, for which we derived the maximum amount of nitrogen losses allowed in each environmental sector to reach related state indicators on a spatial average for Germany. The resulting target sets a limit of nitrogen emissions in Germany of 1053 Gg N yr-1. It could serve as a similar means on the national level as the planetary boundary for reactive nitrogen or the 1.5 {\textopenbullet}C target of the climate community on the global level. Taking related uncertainties into account, the resulting integrated nitrogen target of 1053 Gg N yr-1 suggests a comprehensible INTN of 1000 Gg N yr-1 for Germany.
