The development of cayenne pepper varieties can be optimized by multiple crossings, transgressive segregant selection based on the selection index, and identification of potential anthocyanins. The study objectives were (1) to develop a transgressive segregation index, and (2) to select transgressive segregation cayenne peppers with high productivity and anthocyanins from F3 multiple cross-generation. The study conducted two experiments at the experimental field, Hasanuddin University, from November 2022 to November 2023. The first experiment implemented an augmented design with a randomized complete block design (RCBD) as an environmental design. The genotypes as treatment consisted of two types: 110 lines of cayenne pepper were not repeated, and the 4 older chili varieties as controls were repeated in each block. All genotypes were categorized and divided into five blocks. The second experiment was the validation of the first trial. There were 13 genotypes tested with RCBD design one factor and repeated three times. Based on the study, developing a semi-objective-based selection index with canopy width, fruit weight, and yield was an innovative and effective approach to selecting F3 transgressive segregants of cayenne pepper. High-yielding transgressive lines were identified as G3-2-7-3, G2.6.9–10, G5-12–1-8, and G4.5.2–12. The G3-2-7-3 line was suggested due to its high yield potential and anthocyanin content. However, the anthocyanin content must be examined more deeply, such as using an omics approach. Nevertheless, these lines are still recommended to be continued in yield testing or crossing to produce hybrid lines that have high yield potential and anthocyanin content.

The reliance on fossil inputs of agricultural practices has led to maximizing yields and profitability, even at the expense of environmental sustainability. Implementing circular waste management solutions could help align the economic and environmental goals of farmers while reducing their reliance on fossil inputs. The co-application of anaerobic digestion and pyrolysis has been recognized as a potential solution to assist in the transition towards sustainable agriculture.This research assesses different waste management strategies of the major sidestreams generated in agroecosystems in Finland from a climate impact and financial perspective, particularly focusing on the integration of anaerobic digestion and pyrolysis as an emerging solution.Six waste management options representing manure application, composting, incineration, anaerobic digestion, pyrolysis, and a co-application process of anaerobic digestion and pyrolysis, are simultaneously assessed with cash flow analysis and life cycle assessment.The results indicate that co-applying anaerobic digestion and pyrolysis strengthens the performance of a farm through reduced impact on climate, diversified revenue streams, and increased security of supply, even though the direct, short-term financial benefits remain marginal. The capability of co-application of anaerobic digestion and pyrolysis to reduce the climate impacts within the studied system supports the consensus that sustainable and self-sufficient agroecosystems could be supported by this solution in the future.The adoption of more sustainable agricultural practices requires further expansion of technologies and additional value creation mechanisms, such as stronger employment of carbon markets, to even the economic competition and favor low-carbon operations for practitioners.

Homegardens are one of the oldest agroforestry systems reported around the world. These agroforestry systems are often reported as harbingers of plant biodiversity conservation. However, a comprehensive understanding of these systems from the perspective of species level agrobiodiversity conservation is often missing.This study first visualizes the comprehensive role of homegardens in species level agrobiodiversity conservation and then assesses any variation in agrobiodiversity along diverse Socio-ecological Zones (SEZs) in the study site. The prominent SEZs identified in the study site were Protected Area (PA), Riverine (RI), Rural Market (RM), and Tea Estate (TE). Eight ethnic/linguistic groups were also identified at the study site. Agrobiodiversity inventorying of 192 homegardens from 16 villages was done.The results of the study highlight that homegardens in the study site have high species level agrobiodiversity concentration (101 total tree species reported, 39.58% of homegardens (HGs) had more than 10 varieties of vegetables, 68% had atleast one variety of bamboo, 76% had atleast one banana variety, 20.83% had pond). A total of 64% of HGs had livestock and around 85% had poultry. Moreover, this agrobiodiversity distribution also varied along different SEZs. The livestock diversity indices ranged from 0.49 (TE) to 1.04 (PA). The average plant diversity among homegarden was found to be in the range of 1.09 (PA) to 1.48 (TE) for Shannon, 0.45 (PA) to 0.66 (TE) for Simpson, 0.31 (PA) to 0.71 (TE) for Pileou evenness and 2.39 (PA) to 2.76 (RM) for Margalef. The plant composition reflected the dominance of the food species i.e. an average of 37% in each SEZ. Sorenson similarity index among different SEZs for plant and livestock was found to be highest between the HGs of the PA and RM (0.82). Among the ethnic/linguistic groups, the highest mean number of plant species (51) was found among the Mishing tribe. Also, high similarity index (0.78) was found in plant and livestock composition among the Mishing and the Bodo tribes.The findings imply that HGs exemplify diversified and integrated systems, showcasing their potential to play a crucial role in the development of sustainable food systems.

Aquaculture plays a critical role in Zambia's food and nutrition security. However, aquaculture is highly vulnerable to the effects of a changing climate which can lead to economic losses, and food and nutrition insecurity. In this study, we investigated the perceived effects of climate change on aquaculture production in Zambia, vulnerability factors, and adaptation strategies. We used semi-structured and structured questionnaires to collect data from aquaculture producers in all provinces across the country. Results revealed high (over 80%) awareness of climate change, primarily attributed to literacy levels and access to media. Producers perceived occurrence of climate-related changes such as rising temperature, altered rainfall patterns, cyclones frequency, and disease outbreaks, impacting production costs. Generally, the results indicate a high to medium perception of rising temperature and increased frequency of flooding and droughts across the country. Although rising temperature did not appear to affect aquaculture production cost, the frequency of droughts, floods, cyclones, and disease outbreaks showed a significant association with production costs. Identified vulnerability factors include reliance on a limited range of fish species, absence of insurance coverage, and low adoption of adaptation practices. Vulnerability levels vary across regions, with provinces in agroecological zone I (Eastern, Lusaka, Southern, and Western) showing higher vulnerability. Despite this, many producers aren't implementing adaptation measures due to financial limitations, species diversity constraints, and insufficient knowledge of alternative economic pursuits. Main adaptation strategies involve livelihood diversification and adjustments in fish cultivation periods and infrastructure. To foster aquaculture sustainability amid climate change, critical interventions such as farm insurance, research diversification in aquaculture species, and enhancing producer resilience are necessary.
水产养殖在赞比亚的粮食和营养安全方面发挥着至关重要的作用。然而，水产养殖业极易受到气候变化的影响，从而导致经济损失以及粮食和营养不安全。在这项研究中，我们调查了气候变化对赞比亚水产养殖生产的影响、脆弱性因素和适应策略。我们采用半结构式和结构式问卷，向全国各省的水产养殖生产者收集数据。结果显示，生产者对气候变化的认知度很高（超过 80%），这主要归因于文化水平和媒体渠道。生产者认为与气候有关的变化，如气温上升、降雨模式改变、气旋频发和疾病爆发，会影响生产成本。总体而言，研究结果表明，全国各地对气温升高、洪水和干旱频率增加的感知程度为高到中等。尽管气温上升似乎不影响水产养殖生产成本，但干旱、洪水、气旋和疾病爆发频率与生产成本有显著关联。已确定的脆弱性因素包括对有限种类鱼类的依赖、缺乏保险以及很少采用适应措施。各地区的脆弱性水平不尽相同，农业生态区 I 的省份（东部、卢萨卡、南部和西部）显示出较高的脆弱性。尽管如此，由于资金限制、物种多样性制约以及对替代经济追求的认识不足，许多生产者并未采取适应措施。主要的适应战略包括生计多样化、调整鱼类养殖期和基础设施。为促进水产养殖业在气候变化中的可持续性，有必要采取关键干预措施，如养殖保险、水产养殖品种多样化研究以及提高生产者的适应能力。

Advances in farming technologies and practices have helped farmers to increase crop yields, but continued production increases – while needed to feed a growing global population – are being hindered by climate change and other environmental challenges. Kansas, a globally important region for wheat production, is already experiencing threats to staple crop production. This study explores one possible alternative future for Kansas crop production in which farmers could, by crop switching, continue to grow nutrient-rich crops while responding to hotter temperatures and increasing water demand.We used a combination of climate and crop modeling with simple water budgets to identify optimal crop mixes under anticipated climatic and water constraints. Interviews with Kansas farmers helped identify feasible crop switching options: sorghum instead of corn (maize), winter rye and winter oats instead of winter wheat, and millet instead of soybeans.Our analysis suggests that a sizeable proportion of current Kansas cropland would need to shift to these alternative crops by 2050 to meet anticipated water constraints and produce equivalent nutritional value under projected climate conditions. Alternative crops could increase from 16% of Kansas' crop area in 2021 to 43% of the area in 2050, resulting in a reduction in 2050 crop water demand of 12% relative to that of the current crop mix. This crop water demand reduction would be concentrated in parts of the state that will experience the greatest change in water needs between today and mid-century due to changing climate conditions.Our analysis shows that, by changing (diversifying) the mix of crops grown, it is biophysically possible for crop production in Kansas to be both sustainable and resilient under future climate conditions. However, achieving a more climate-resilient crop mix on the ground, in Kansas and elsewhere, will require major shifts in the broader agricultural system. Food companies, agricultural lenders, and policymakers can play a key role in enabling farmers to adapt cropping systems in the face of climate and environmental challenges.

The global pursuit of sustainable development has highlighted the Circular Bioeconomy (CBE) as a key framework for resilience and sustainability. CBE, which focuses on regenerating natural resources and minimizing waste, encompasses sectors like agriculture, waste management, and renewable energy. Agricultural Extension Services (AES) play a pivotal role within this paradigm, serving as conduits for disseminating knowledge, providing training, and fostering innovation in the agricultural sector. Indonesia, with its rich agricultural heritage and diverse natural resources, stands as a key player in the global agricultural landscape. However, the country faces challenges such as land degradation, deforestation, and climate change impacts, necessitating a shift toward sustainable agricultural practices. This article examines the potential of CBE in Indonesia, particularly the role of AES in its adoption. AES bridge the gap between research, policy, and implementation, equipping farmers with the necessary tools and information for transitioning to CBE models. Despite challenges such as limited awareness, technological barriers, and policy constraints, strategic interventions and collaborative efforts can pave the way for effective CBE implementation in Indonesia. Strengthening collaboration, enhancing capacity-building efforts, advocating for supportive policies, mobilizing financial resources, and fostering public awareness are key strategies in this endeavor. In conclusion, successful CBE adoption in Indonesia depends on the active involvement of AES. Through embracing CBE principles and leveraging AES capabilities, Indonesia can achieve a sustainable and prosperous future, fostering resilience, economic growth, and environmental integrity.

Today, chemical inputs play an important and crucial role in increasing the production rate of agricultural products and the income of farmers in Iran. However, in parallel with this beneficial effect, the widespread and indiscriminate use of such inputs is considered to be one of the most significant barriers to environmental sustainability in Iran. The main objective of this research is to model the acceptance of the use of biological inputs among farmers living in the southwest of Iran. The research study was conducted using the cross-sectional survey method. The statistical population included all farmers of Meidavoud district located in Baghmalek county, southwest of Iran (N = 1,400). A sample of 302 individuals was selected according to Morgan’s sample size table and random sampling method. A questionnaire was used to collect the data, the validity of which was confirmed by a panel of experts, and its reliability was approved by various coefficients. The data were analyzed using SPSSV26, Smart PLS3, and AMOS software. The results of the structural equations showed that among the variables influencing farmers’ behavior toward biological inputs, the attitude and willingness variables could predict 80% of the variation in farmers’ behavior. In addition, attitude, ease of use, and usefulness were identified as effective factors in farmers’ willingness to use biological inputs. According to the results of the path analysis, the variables perceived usefulness and ease of use could predict 67% of the changes in farmers’ attitudes. To convince farmers and promote desirable attitudes that, in turn, influence their willingness to use biological inputs, some persuasive interventions seem to be necessary. Farmers need to be externally or internally motivated if they adopt environmentally friendly practices such as use of biological inputs.

Farmers need to be externally or internally motivated if they adopt environmentally friendly practices such as use of biological inputs.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":" 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141830024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This present research was designed to investigate the anti-inflammatory and immune-modulatory effects of a 50% hydroethanolic extract of “Gola” guava fruit (GF50%) and guava leaf (GL50%) against papain-induced knee osteoarthritis (KOA).Sixty Sprague–Dawley rats were divided into five groups (10 rats/ group): T0 (negative control), T1 (positive control), T2 (200 mg/kg GF50%), T3 (400 mg/kg GF50%), T4 (200 mg/kg GL50%), and T5 (400 mg/kg GL50%). Physical parameters were evaluated throughout the trial, while biochemical, histopathological, and radiographic analyses were performed at 0, 15, and 30 days. The histopathological and radiographic analyses were evaluated using the Osteoarthritis Research Society International (OARSI) score and Kellgren–Lawrence (KL) classification systems, respectively.The T1 group demonstrated a significant increase in knee diameter, confirming successful OA induction. The T5 group maintained a significantly lower body weight at day 30, and the T3 group exhibited the highest weight gain. The high dose of GL50% (400 mg/ kg) effectively reduced knee inflammation and significantly downregulated myeloperoxidase (MPO), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). In contrast, it significantly (p < 0.001) upregulated the serum and knee capsule tissue superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). In addition, histopathological and X-ray examinations also confirmed the chondroprotective potential of GL50% extract against OA. Consequently, 400 mg/kg GL50% exhibited anti-inflammatory and chondroprotective potential by lowering oxidative stress and pro-inflammatory cytokines and elevating antioxidant status. These findings could provide a theoretical basis for understanding the mechanism and potential medicinal value of guava fruit and leaf in treating KOA.

The Blackfeet Nation in northwestern Montana, United States, is implementing its Agriculture Resource Management Plan (ARMP), an Indigenous-led, sustainable agriculture plan prioritizing economic development for Indigenous producers, intergenerational health and well-being of Amskapi Piikani Blackfeet people, and ecological and cultural sensitivities within this sovereign nation and its traditional territories. Since the passage of the American Indian Agricultural Resource Management Act of 1993, only three Tribes have drafted and finalized Agricultural Resource Management Plans (ARMPs). The Blackfeet ARMP is now being held up as a national model of Tribal sovereignty. “Blackfeet Innovation Pathways to Food Sovereignty,” an Indigenous-led research project, emerged from the Blackfeet Nation’s community-based strategic planning process identifying gaps, systemic barriers and impactful solutions for achieving Blackfeet food sovereignty through the implementation of the Blackfeet Nation ARMP, along with research influenced by the ARMP. This paper provides a community case study of the ongoing process and offers a translational model of sustainable agriculture and food sovereignty within Indigenous lands to improve the economic futures of producers and their families, as well as health outcomes for Native communities.

California is the largest agricultural economy in the United States; however, its current and projected climate risks pose significant challenges. Farmers will need to adapt to climate change in their farming practices. The goal of this needs assessment was to understand farmers' perceptions and experiences with climate change exposures; the risk management practices they currently use; and what tools and resources would assist them in making strategic decisions. A statewide survey was conducted through Qualtrics with farmers (n = 341). Results showed that 67% of the farmers agree (agree + strongly agree) that climate change is happening, and 53.1% agreed that actions are required. Moreover, historically underrepresented farmers were very concerned about climate change-related impacts related to water, temperatures, and natural disasters. Farmers are currently implementing adaptation practices related to water management, soil health, and renewable energy and are also seeking insurance and government assistance programs to increase agricultural resilience. They also expressed interest and a high need for information on those adaptation practices to acquire skills and knowledge to manage various challenges of farming in variable climates. Also, the assessment established that farmers (47.5%) use decision-support tools, mostly weather stations (22.4%); and 51.9% indicated their interest in using online tools designed to translate climate information into forms that support production decision-making. Farmers (60.8%) responded that they would or may attend workshops to learn about adaptation practices. The findings of this needs assessment will inform the development of extension education programs on climate-smart agriculture for farmers in California and elsewhere.
