Food systems contribute one-third of global anthropogenic greenhouse gas (GHG) emissions, roughly 16.5 GtCO2e year−1from a total 54 GtCO2e year−11,2, with both pre- and post-production phases representing a high and increasing share of total emissions3. The Food and Agriculture Organizati...
controlled by local conditions (for example, methane from oil and natural gas systems, rice cultivation, and waste management).Despite their preliminary nature, these 31 inventories represent significant progress in meeting country commitments under the United Nations Framework Convention on Climate Change...
According to a new global study, greenhouse-gas emissions from food systems have been systematically underestimated for a long time — but there are significant opportunities to reduce them. Greenhouse-gas contributions from various parts of the global food system. Image Credit: Tubiello et al., ...

These gas samples were delivered to the laboratory and analyzed within 48 h. The air temperature (Ta) was measured using a portable digital thermometer (JM 624, Jinming, China). The water temperature (Tw), dissolved oxygen (DO) concentrations, and pH were determined by a portable Multi-...
The definition of a greenhouse gas is at the same time very simple and very complicated for the ordinary man (or woman !) : such a gaz is “just” a gas mixed in the atmosphere thatabsorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases bec...
However, it can be stated that the effect of N2O gas released from the produce residues is greater. Suggestions such as improving feed rations and maintaining herd management strategies within certain patterns to reduce the level of enteric fermentation may contribute to the process. In produce ...
