The study specifically examines the impact of the livestock and dairy development project (LDDP) intervention on food security in rural livestock farming households in Bangladesh. We gathered data, we are employing simple random sampling, and collecting 180 cross-sectional primary data from both LDDP participants and non-participants. Descriptive statistics, inferential statistics, and propensity score matching approaches were utilized to achieve our research objectives. Livestock farming households with LDDP participants exhibited higher food security, with beneficiaries surpassing non-participants by 52 % and 40 %, respectively. The mean per capita calorie intake for LDDP participant households was 1966.134 (Kcal), whereas non-participant households recorded 1762.130 (Kcal). The results demonstrate that LDDP intervention significantly and positively impacts food security, women's empowerment, household welfare, and income. These interventions have the potential to enhance nutrition and boost household income, thereby contributing to the stability of food security. Consequently, we recommended an expansion of LDDP intervention, encompassing less resourceful farmers with adequate logistical support. This study illustrates how employing propensity score matching method (PSM) and implementing the LDDP intervention can effectively improve food security in livestock farming households in Bangladesh.</p></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"9 ","pages":"Article 100098"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772801324000265/pdfft?md5=5cc842cd28876063ccdaa879ee40f7e4&pid=1-s2.0-S2772801324000265-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141963912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 1000 g of homogenized contaminated soil was amended with 10.50 g of NPK fertilizer and 107.50 g of compost to achieve a nitrogen concentration of 0.2 %. To establish a 0.4 % nitrogen concentration, 23.90 g of NPK fertilizer, 243.54 g of compost, and 2 ml of cattle bile were used. These amendments were applied in various combinations to create the following microcosm treatments: A, B, C, D, A2, B2, C2, D2, and a control. The microcosms, along with the control were incubated for 6 weeks in triplicate. Throughout this period, several parameters were monitored every two weeks, including pH, nitrogen (N), potassium (K), phosphorus (P), moisture content, organic carbon, organic matter, total heterotrophic bacterial count (THBC), and total petroleum hydrocarbon (TPH) concentration. The results showed significant differences (<em>p</em> < 0.05) in TPH content across the microcosms during the four sampling periods. By the end of the 6-week incubation, the TPH residual concentration varied between 1.58 mg kg<sup>-1</sup> and 20.61 mg kg<sup>-1</sup>, corresponding to degradation rates of 98.43 % and 79.58 %, respectively, from an initial TPH concentration of 100.91 mg kg<sup>-1</sup>. Microcosm B2 demonstrated the highest hydrocarbon removal efficiency (98.43 %), while the control showed the lowest efficiency. The order of degradation efficiency among the microcosms was B2 > <em>B</em> (94.89 %) > C (94.64 %) > <em>A</em> (94.13 %) > D2 (93.62 %) > A2 (93.51 %) > C2 (92.45 %) > <em>D</em> (91.44 %). The study also found that pH and nitrogen levels were related to the reduction in hydrocarbon content. Microcosms with a 0.4 % nitrogen concentration showed a higher rate of nitrogen consumption compared to those with a 0.2 % concentration. Additionally, changes in pH were observed as hydrocarbon degradation progressed. This study further applied cluster analysis, Bayesian statistics, and multiple linear regression to evaluate the effects of treatments on soil quality over time. Cluster analysis showed increasing dissimilarity between merged clusters, while Bayesian analysis revealed positive trends in parameter estimates in Weeks 2 and 4. Regression analysis indicated significant impacts of Weeks 2, 4, and 6 on Week 0, with F-statistics of 8.475 (<em>p</em> = 0.016), 9.804 (<em>p</em> = 0.004), and 3.759 (<em>p</em> = 0.037), though multicollinearity reduced the predictive power of individual coefficients.

Targeting food loss and waste prevention benefits various aspects such as food security, productivity, economic growth, climate change mitigation, resource conservation, and waste management. Understanding the causes of food loss and waste is crucial for the design of effective solutions and their prioritisation. The purpose of this study was to investigate the risk factors and underlying causes of FLW in leafy vegetables, spanning from agricultural production to retail. To achieve this, the research methodology encompassed a case study conducted among small-scale producers and retailers. A comprehensive approach was adopted by integrating a systematic literature review of global food loss and waste causes and those specific to the Latin American context. This approach was complemented by exploratory research, involving interviews with various stakeholders, coupled with root-cause analysis. A methodology was developed for the creation of a causal map, incorporating the 'Five Whys' technique, the current reality tree, and an interrelationship diagram. The study's findings underscore the critical role of retailer-supplier dynamics in the management and flow of products, identifying a significant research gap in the development of comprehensive strategies for waste reduction. By exploring these dynamics, particularly in the context of take-back agreements and the lack of public policies incentivizing food loss and waste reduction, the research reveals the multifaceted nature of food loss and waste and the necessity for collaborative efforts across the supply chain to mitigate its impacts. The application of the structured methodology provides valuable insights into the root causes and critical risk factors of FLW, offering a foundation for the development of integrated strategies aimed at reducing food loss and waste and advancing towards global sustainability goals.</p></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"9 ","pages":"Article 100108"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772801324000368/pdfft?md5=e0c907a1c5d8efbba049ea8f9694c467&pid=1-s2.0-S2772801324000368-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142136539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
