Breastfeeding relies on maternal metabolism and local support systems, whereas commercial milk formula depends on dairy production, industrial processing, packaging, and extensive supply chains. Comparative analyses report higher greenhouse-gas and water burdens for commercial milk formula than for breastfeeding. Globally, commercial milk formula use among infants under 6 months of age adds roughly 5.9-7.5 billion kg of carbon dioxide equivalent annually. Pumping and bottle-feeding add material, electricity, and cleaning-related burdens relative to feeding at the breast, but available evidence generally indicates lower impacts than commercial milk formula, although estimates depend strongly on assumptions about maternal diet and pumping practices. Climate change and water insecurity can also threaten breastfeeding through heat stress, food insecurity, and disruptions during disasters and emergencies. Moreover, uncontrolled formula donations during upheavals, while well-intended, impede continuation of breastfeeding. Collectively, these pressures can generate a reinforcing feedback loop: climate shocks undermine breastfeeding, increasing reliance on resource-intensive substitutes that further strain water and energy systems. Recognizing breastfeeding as both a mitigation and resilience issue highlights co-benefits for maternal and child health and climate action and points to practical policy levers, including paid maternity leave, workplace lactation protections, responsible marketing of commercial milk formula, and continuity of lactation support during emergencies that are needed to align optimal infant feeding with climate adaptation planning.</p>","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"10 ","pages":"1919608"},"PeriodicalIF":4.1,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13576063/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148978251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimization effects were evaluated through sensory evaluation, physicochemical analysis, and correlation analysis. Results showed the optimal parameter combination for Anhua region was fermentation temperature of 55 °C and fermentation time of 20 days, achieving a sensory score of 91.2 points (highest among three regions), representing a 10.8% improvement over controls. Theaflavins showed highly significant positive correlation with sensory scores ( r = 0.83), while tea polyphenols exhibited significant negative correlation ( r = −0.66), establishing theaflavins as the core quality regulation factor. Under optimized conditions, theaflavin content increased by over 60% compared to traditional processes across all regions. Principal component analysis revealed the first two components explained 82.6% of total variance, with regions displaying gradient distribution in quality characteristics.

Purposive, multi-stage, and random sampling procedures were followed for the selection of sampling units based on the availability of agroforestry land use systems. A total of 19 tree species belonging to 9 families and 12 genera were documented. Species like Populus deltoides, Populus nigra, Salix alba, and Salix fragilis were found to be highly preferred for fuelwood, fodder, and small timber extraction. The total green house gas (GHG) emission potential of this extracted material is 64.35 tC and 235.95 tCO 2 , with the maximum CO 2 emission from Salix alba (28.05 tCO 2 ). A total quantity of 143 quintals of biomass is extracted annually from the 19 tree species utilized for fuelwood, fodder, and small timber, resulting in an average avoided deforestation potential of 75.26 m 3 . The highest offset value of US$ 1492.79/Mg was recorded for Horti-silvi-pastoral systems, followed by Homegardens (US$ 1414.51/Mg), and the minimum offset value of US$ 626.38/Mg was recorded for Boundary plantations. On an average, a single sampled household helps to sequester 4.7 Mg of carbon annually in the present study. Therefore, a cluster-based approach by bundling villages together in the entire Ganderbal district would result in approximately sequestering 213,196 Mg CO 2 e and hence would yield US$ 536,620 per annum.

It is helpful to express the social activities and civilization of a society. It leads people from instinct to inspiration, through process and system of enquiry, command, and control. It is helpful to create a common pool of ideas, strengthens the feeling of togetherness through the exchange of messages and translates through into real action. As the world has advanced and become more developed, the task of communication has become more complex. However, unless some basic structural changes are introduced, the potential benefits of technological and communication development will hardly be put at disposal of the majority of population. Communication system and network is the key input in increasing the performance in agricultural production. Therefore, the communication is considered as the most powerful input which brings substantial upliftment in the socio-economic status of individuals. Models can be best used for explanatory purposes only when we are alive to their limitations, as they are by no means a simulacrum of reality, but only a simplified image of it. The present study was conducted in hilly district Reasi of Union Territory of Jammu and Kashmir which was selected purposively. Out of 12 C.D Blocks only 4 C.D. Blocks namely Katra, Reasi, Pouni, and Thuroo were selected randomly. A sample of 25 per cent Gram Panchayats from each selected block was selected randomly. A sample of 25 per cent farmers (150) was selected randomly from the selected villages. The Cobb-Douglas equation was worked out in the following way between the dependent variable (communication behavior) and independent variables X1, X2, X3, X4, X5, X6, X7, and X8 (size of land holding, annual income, interpersonal interaction, innovation proneness, value orientation, achievement motivation, socio-economic status, and education respectively). The value of R2 found in case of linear function was lesser than that in the exponential function. So, exponential model (Cobb-Douglas Model) was considered as the best fit. Through the study it was inferred that the communication behavior initially increases with increase in the input behavior (independent variables) but with the decreasing ratio. With the increase in independent variable, communication behavior (dependent variable) also increases but at a certain saturation point communication behavior of the farmers does not increase. The research is useful to assess the communication behavior of farmers. We can change the communication behavior of the farmers accordingly. If the (input) independent variables of the farmers are known then the (output) dependent variable can be found easily by utilizing this model.","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://public-pages-files-2025.frontiersin.org/journals/sustainable-food-systems/articles/10.3389/fsufs.2025.1714710/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147910485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soils were sampled randomly from three soil depths viz. 0–25, 25–50 and 50–75 cm and were analysed for total organic carbon (TOC), active and passive carbon fractions and bulk density to compute SOC stocks. Converting fallow land to other land uses significantly ( p &lt; 0.05) increased TOC, with surface (0–25 cm) content rising from 11.0 g kg −1 in fallow land to 19.0 g kg −1 in forests, 18.9 g kg −1 in apple orchards and 17.5 g kg −1 in vegetable farms. Similar pattern of higher TOC in subsurface depths under forests, apple orchards and vegetable farms were observed in comparison to uncultivated fallow lands. Carbon fractions and stocks followed the pattern as forest &gt;apple &gt; vegetable &gt; fallow land across all depths, with forests and apple orchards storing the most carbon. The highest CMI content was observed in the soils under forest land use (203.8) followed by vegetable (169.3).

There is an urgent need for sensitive, selective, and reliable analytical methods for its detection in complex food matrices. Methods We developed a novel ratiometric fluorescence immunoassay based on gold nanoparticles encapsulated in manganese dioxide nanosheets (AuNP@MnO₂), which exhibit intrinsic oxidase-like activity. The assay utilizes dual-emission fluorescence (at 430 nm and 570 nm) and quantifies T-2 toxin by measuring the fluorescence intensity ratio (F₄₃₀/F₅₇₀), thereby minimizing environmental and instrumental variability. Results The method demonstrated excellent linearity over a wide concentration range (0.082–60.00 ng/mL) with a low detection limit of 0.068 ng/mL. High specificity was achieved, showing negligible cross-reactivity against common mycotoxins such as aflatoxin B₁, zearalenone, fumonisin B₁, ochratoxin A, and deoxynivalenol. In spiked corn samples, recoveries ranged from 76.94% to 99.48%, confirming good accuracy, stability, and reproducibility.

As people become more aware and prefer natural clean-label foods, the demand for safer options from the industry is growing. In this situation microalgae can be a strong natural source of preservatives. They are rich in active compounds that show both antioxidant and antimicrobial effects. Microalgal extracts give a green way to improve food safety and shelf life. This review discusses major antioxidant constituents of microalgae, including carotenoids (e.g., astaxanthin, β-carotene), phenolics, and vitamins that reduce oxidative degradation of food matrices. Mechanisms of action, delivery modes, and incorporation into active packaging and food coatings are covered. Despite efficiency challenges associated with extraction, compound stability, and large-scale industrial production, breakthroughs in bioprocessing and biotechnology are rapidly expanding the boundaries of commercial application.
