Therefore, restaurants could play an important role in mitigating the increase in overweight and obesity and could improve diet quality by offering healthier and more sustainable food choices i. Menu-engineering in restaurants - adapting portion sizes on plates to enhance vegetable consumption.
Reinders Marlijn Huitink S. Coosje Dijkstra Anna J. As fish stocks can not be modelled with the MPI-ESM it was assumed that also the amount of food provided by this sector remains constant over time. Climate change imposed limitations on potential food production. The future demand for livestock products in a scenario where most of the population lives in large cities, rather than in rural areas, will dictate consumption trends in coming years Kearney, ;FAO, The demand for livestock products will more than double by compared with Steinfeld et al.
In developing countries, the demand will increase as a consequence of increasing population and net income FAO, FAO, , , which are usually associated with increases in demand for animal products.
Methane production in dairy cows. Individual cow variability in methane production. Methods and Metrics for the assessment of Nitrogen and Phosphorus use efficiency for global livestock supply chains.
Most of the gains in global food and feed production have been achieved through the increased use of the major nutrients nitrogen N and phosphorus P. The N and P losses to air and water bodies …" [more]. The Nutrient technical advisory groups: Rational The life cycle assessment LCA framework of livestock sector is challenged by some outstanding methodological issues related to the accounting flow…" [more].
Effect of release rate of the SF6 tracer on methane emission estimates based on ruminal and breath g The release rate RR of sulphur hexafluoride SF 6 gas from permeation tube in the rumen appears to be positively related with methane CH 4 emissions calculated using the SF 6 tracer technique. Gas samples of breath and ruminal headspace were collected simultaneously in order to evaluate the hypothesis that transactions of SF 6 in the rumen are the source for this relationship.
Elevated atmospheric [CO2] from a natural soda spring affects the initial mineralization rates of na Naturally senesced leaves from the grasses Holcus lanatus Yorkshire fog; C3 photosynthetic pathway and Pennisetum clandestirum Kikuyu; C4 photosynthetic pathway , grown in elevated atmospheric [CO2] surrounding a natural soda spring, were decomposed within respiratory chambers and the initial mineralization 0—30 days of the litter measured.
Significantly greater rates of initial Decomposability of C3 and C4 grass litter under different concentrations of atmospheric carbon dioxi Elevated concentrations of atmospheric CO2 can influence the relative proportions, biomass and chemical composition of plant species in an ecosystem and, thereby, the input of litter nutrients to soil. Plant growth under elevated CO2 appears to have no consistent effect on rates of litter decomposition; decomposition can, however, differ in C3 and C4 plant material from the same CO The influences of various preparation conditions on Li2Al2Si3O10 forming were investigated.
