Summary: Ruminants play a central role in the economic and nutritional life of sub-Saharan Africa, but cattle are blamed for their disproportionately large negative environmental impact due to greenhouse gas emissions. However, the mechanism behind excessive emissions on some farms is not well understood. This study used individual animal records to quantify farm-level greenhouse gas emission intensities of smallholder farms in Western Kenya. The results showed a wide range of emission intensities, with milk being responsible for the majority of emissions. Enteric methane production was found to be the main contributor to emissions. The data collected from individual animals on smallholder farms demonstrated the variability in emission intensity and provided indicators on how to achieve low emission intensity in these environments.

Summary: China is a major producer of green tea, especially from small farmers. This study analyzed the carbon footprint of green tea produced by smallholder farmers in Shaanxi Province, using the life-cycle assessment method. The results revealed high carbon emission intensities during processing and cultivation stages, mainly due to coal use, complex processing procedures, and older equipment in processing, and fertilizer production and application in cultivation. The study suggests the importance of establishing a scientific fertilization system, optimizing processing equipment and energy utilization, and promoting the concept of low-carbon consumption for reducing carbon emissions by smallholder farmers. Furthermore, it emphasizes the need to focus on carbon emissions from the production processes of small farmers.

Summary: The building industry generates significant carbon emissions, contributing to the worsening of the greenhouse effect. Building Information Modeling (BIM) is an effective method for assessing embodied carbon, but the lack of compatibility among different BIM software hinders this process. This paper proposes a six-step methodology based on Industry Foundation Classes (IFC) to calculate embodied carbon. The methodology provides a transparent process at various levels, enabling impartial carbon audits. Additionally, an innovative IFC tool, NMBIM, is developed to automate the process, allowing for quick assessment and optimization of embodied carbon in multi-participant collaborative works using heterogeneous BIM models.

Summary: The rapid intensification of animal and crop production in Chinese dairy farms has led to high nutrient losses and food-feed competition. This study found that Chinese dairy farms heavily rely on imported feed and are not closely connected to crop production. On-farm croplands play a minor role in feed supply but are overloaded with cattle manure. The average nutrient use efficiencies were low, indicating inefficient utilization of nutrients. Farms with higher milk yields and moderate concentrate use performed better in nutrient use efficiencies and food-feed conversion ratios.

Summary: When designing healthy and sustainable diets, the quality of nutrients, particularly proteins, is just as important as the quantity. Assessing protein quality based on amino acid concentration and digestibility allows for ranking of proteins and evaluation of complementarity between protein sources. Integration of protein quality on a dietary level should be done based on measurements of individual amino acids, while considering the effects of processing.

Summary: Livestock feed production is a major consumer of freshwater and arable land. This study examines the impact of different pig diets on freshwater usage for pork production. Three feeding scenarios were explored: standard diets, local diets, and by-product diets. The water footprint and competition for water resources were calculated for each scenario using the water footprint method and the water use ratio. The study found that by-product diets performed the best in terms of freshwater usage. Consideration of human edibility and the broader food system is important when determining pig diets.

Summary: This study analyzed the feed-food competition in aquaculture using natural trophic levels (TLs) and species-specific human-edible protein conversion ratios (HePCRs). The results showed that under current feed use, carp, tilapia, and shrimp are net contributors of protein, requiring 0.6 kg of human edible protein to produce 1 kg of fillet/meat protein. However, the use of food-competing ingredients like soya bean meal and fishmeal increases the HePCR to 2, making these species become net consumers of protein. To prevent this, the use of high-quality food-competing ingredients should be minimized in aquaculture feed.

Summary: This study characterized the sustainability certification standards used in dairy production and identified 19 standards that qualify as sustainability certification based on selection criteria. The standards vary in terms of organization type, number of indicators, sustainability themes covered, and the balance of credibility, accessibility, and continuous improvement. The environmental pillar is most frequently addressed, while the economic pillar is least addressed. The analysis shows that credibility and accessibility are often described and assured, but continuous improvement is less focused on. The variability in standards allows farmers to choose a standard that aligns with their beliefs or stage of development, but it may also create mistrust in standards.

Summary: The study aimed to examine social networks in dairy value chains in Kenya and understand how power relationships and trust among actors influence milk quality behavior. The researchers conducted stakeholder analysis using the Net-Map tool and analyzed social networks using VisuaLyzer software. They found that formal value chains had more actors and dense social networks with power asymmetries and limited trust, while informal value chains had fewer actors and less dense social networks with higher trust due to personal relationships. They also discovered that milk quality was perceived to be higher in the formal value chain. The study highlights the importance of addressing power asymmetries and enhancing trust to improve compliance with milk quality standards.
