Objectives: The study was undertaken to investigate the greenhouse gas (GHG) emission from livestock in Bangladesh.
Materials And Methods: The GHG emission inventory of livestock in Bangladesh was estimated according to the tier 1 approach of the Intergovernmental Panel on Climate Change (IPCC) using livestock population data from 2005 to 2018. It was also extrapolated for the next three decades, according to the growth of the livestock population.
Results: According to the calculation, the GHG emission from livestock was 66,586 Gg/year CO equivalent (COe) in 2018. This emission may rise to 69,869, 80,618, 94,638, and 113,098 Gg/year COe in 2020, 2030, 2040, and 2050, respectively. The share of enteric methane, manure methane, direct nitrous oxide emission, and indirect nitrous oxide emission in the total GHG emissions represented 44.0%, 3.6%, 51.5%, and 0.9%, respectively, in 2018. It may arise at a rate of 1.54%-1.74% annually until 2050.
Conclusion: The GHG inventory may guide professionals to formulate and undertake the effective mitigation measures of GHG emissions from livestock in Bangladesh. However, this inventory can be amended following the tier 2 approach recommended by the IPCC if necessary data are available at the national level.

In response to the 2023 "Action Plan for Methane Emission Control" in China, which mandates precise methane (CH) emission accounting, we developed a dynamic model to estimate CH emissions from fossil-fuel and food systems in China for the period 1990-2020. We also analyzed their socioeconomic drivers through the Logarithmic Mean Divisia Index (LMDI) model. Our analysis revealed an accelerated emission increase (850.

Climate change significantly challenges smallholder mixed crop-livestock (MCL) systems in sub-Saharan Africa (SSA), affecting food and feed production. This study enhances the SIMPLACE modeling framework by incorporating crop-vegetation-livestock models, which contribute to the development of sustainable agricultural practices in response to climate change. Applying such a framework in a domain in West Africa (786,500 km) allowed us to estimate the changes in crop (Maize, Millet, and Sorghum) yield, grass biomass, livestock numbers, and greenhouse gas emission in response to future climate scenarios.

Reducing enteric methane emissions from livestock is a key environmental challenge, as methane is a major pollutant. The complexity of animal biology and diverse diet compositions make it difficult to develop strategy to control methane production. This study examined the use of plant phenolic extracts of Madhuca longifolia (ML-7) as a feed additive combined with various ruminant diets and dosages to find an effective supplement to reduce methane emissions.

"Low Carbon Brazilian Beef" (LCBB) represents a Brazilian concept brand that certifies livestock systems adopting specific technical guidelines to minimize methane gas emissions from cattle. Understanding consumers' perceptions of this brand concept can help develop strategies to promote its consumption. The objective of this study was to investigate the perception of Brazilian consumers living in the state of Rio de Janeiro regarding the LCBB through free word association and to evaluate the influence of socio-demographic variables, green consumption values and frequency of beef consumption in associations.

Livestock directly contribute to greenhouse gas emissions, mainly through enteric fermentation and to a lesser extent manure management. Livestock feed composition plays a crucial role in diet quality and the resulting emissions from livestock. Diet composition varies seasonally particularly in tropical environments with long dry periods.
