“…Synergies were also identified, primarily between increasing operating profit and reducing soil N loss, and between reducing feed costs and mitigating GHG emissions. Also, the model results provided alternatives with maximum operating profit and lower animal feed costs by incorporating more on-farm grown fodder area, and specifically an opportunity to increase the area of Jara-1 hybrid grass by 67%. …”

Comparative Rumen Metagenome and CAZyme Profiles in Cattle and Buffaloes: Implications for Methane Yield and Rumen Fermentation on a Common Diet por Malik, P.K., Trivedi, Shraddha, Kolte, A.P., Mohapatra, A., Biswas, S., Bhattar, A.V.K., Bhatta, R., Rahman, Habibar

“…As methane yield due to the similar diet composition, feed ingredients, rumen fermentation, and microbiota composition did not vary, these results indicate that the microbiota community structure and methane emissions are under the direct influence of the diet and environment, and the host species may play only a minor role until the productivity does not vary. …”

Socio-economic, environmental and health impacts of dietary transformation in Bangladesh: A scenario simulation study for the period 2022-2040 por van Dijk, Michiel, de Lange, Thijs

“…The change in diets, and in particular the worldwide rise in the consumption of animal protein, also has had a strong negative impact on the environment, including loss in biodiversity, water resource depletion, deforestation, and an increase in greenhouse gas (GHG) emissions. There is consensus that the transformation towards sustainable healthy diets is regarded as a key strategy to improve human nutrition and health, combat poverty and promote environmental sustainability. …”

Analysis of the implementation of the policy guidelines for sustainable bovine livestock farming 2022–2050 por Sandoval, Danny, Triana Ángel, Natalia, Burkart, Stefan

“…However, the extensive nature of this activity generates strong social and environmental impacts such as land grabbing, expansion of agricultural frontier, increased greenhouse gas emissions, and deforestation. One of the main initiatives to promote the productive transformation towards more sustainability are the Policy Guidelines for Sustainable Bovine Livestock Farming 2022-2050 (Lineamientos de Política para la Ganadería Bovina Sostenible; LPGBS), which arose from a series of conversations among sector institutions and the national government. …”

Small-scale farms in the western Brazilian Amazon: can they benefit from carbon trade? por Carpentier, Chantal Line, Vosti, Stephen A., Witcover, Julie

“…Recently scientists have started to examine how land-uses and land-use technologies can help mitigate carbon emissions. The half million small-scale farmers inhabiting the Amazon frontier sequester large stocks of carbon in their forests and other land uses that they might be persuaded to maintain or even increase through the Clean Development Mechanism (CDM) of the Kyoto Protocol. …”

“…This study is part of the CGIAR Research Initiative on Nature-Positive Solutions for shifting agrifood systems to more resilient and sustainable pathways" (NATURE+), which aims to promote sustainable agricultural productivity through nature-positive solutions (NPS) by addressing three critical challenges: Land Degradation: Industrial agriculture, while ensuring large-scale food production, has caused severe environmental harm, including 80% of global deforestation, threats to 86% of endangered species, significant biodiversity loss, and up to 37% of global greenhouse gas emissions. It also depletes water and soil health, reducing crop resilience and lowering farming incomes and nutrition outcomes. …”

An economic evaluation of an intensive silvo-pastoral system in San Martín, Peru por Junca Paredes, John Jairo, Durango Morales, Sandra Guisela, Burkart, Stefan

“…The SPSi under study is in the evaluation phase, integrates grasses, legumes, shrubs, and trees, and has the potential to enhance cattle farming profitability while simultaneously offering environmental benefits such as improved soil health and reduced greenhouse gas emissions. Through a discounted cash flow model over an eight-year period, key profitability indicators—Net Present Value (NPV), Internal Rate of Return (IRR), Benefit–Cost Ratio (BC), and payback period—were estimated for four dual-purpose cattle production scenarios: a traditional system and three SPSi scenarios (pessimistic, moderate, and optimistic). …”
