	abstract = {The effect of different systems of N fertilization on nitrogen balance and N transformation in the soil was studied in
long-term stationary experiments (1991{\textendash}2002) with successive growing of maize. Average dry matter yield for the control
without fertilization in the period 1991{\textendash}2002 was 11.67 t of dry matter per ha, which was by 2{\textendash}2.9 t less than for
fertilization treatments. Statistically significant differences between the control and fertilization treatments were determined
for the first time in the 4th experimental year. Average nitrogen uptake by the aboveground biomass was 116 kg N/ha
for the control, 162{\textendash}170 kg N/ha for fertilization treatments. All experimental treatments had a negative balance of N inputs
and outputs, and it was {\textendash}1394 kg N/ha for the control (for 12 experimental years). After the application of mineral
fertilizers, a lower content of total carbon and nitrogen was measured in the topsoil compared to the control and treatments
with organic fertilization. The changes in the nitrogen regime of soil were characterized by the content of extractable
nitrogen and carbon in extractions by 0.01M CaCl2. With respect to the content of mineral nitrogen and easily
extractable organic nitrogen and carbon in the topsoil the control was most stable followed by farmyard manure treatment.
Soil lysimeters were installed in these experiments (depth 60 cm, size 0.2 m2). For an eight-year period (1994/2002)
11.78 kg N-NO3 {\textendash}/ha were determined in lysimetric waters. These values for fertilization treatments ranged from 21.0 to
58.2 kg N-NO3 {\textendash}/ha. Straw application reduced nitrate contents in lysimetric waters.},

Here we investigate {\textquoteright}innovations{\textquoteright} influencing such emissions. These innovations mainly address agriculture: reduced meat diets, urban gardening, genetically modified crops, and precision farming, but also more distant options such as vertical farming and cultured meat production, that is, indoor agriculture. While the latter approaches, which allow full management of effluents, seem very promising in terms of emission control, the cost estimates available would rule out any practical relevance. Technologies that currently seem more realistic offer much smaller mitigation potential. Information on energy need, greenhouse gas emissions, and land requirements feed into a semi-quantitative assessment, which delivers information in a format useful for existing European policy tools. {\textcopyright} 2014 Elsevier B.V.},

	abstract = {Altering diets is increasingly acknowledged as an important solution to feed the world{\textquoteright}s growing population within the planetary boundaries. In our search for a planet-friendly diet, the main focus has been on eating more plant-source foods, and eating no or less animal-source foods, while the potential of future foods, such as insects, seaweed or cultured meat has been underexplored. Here we show that compared to current animal-source foods, future foods have major environmental benefits while safeguarding the intake of essential micronutrients. The complete array of essential nutrients in the mixture of future foods makes them good-quality alternatives for current animal-source foods compared to plant-source foods. Moreover, future foods are land-efficient alternatives for animal-source foods, and if produced with renewable energy, they also offer greenhouse gas benefits. Further research on nutrient bioavailability and digestibility, food safety, production costs and consumer acceptance will determine their role as main food sources in future diets.},
