<p>Japan is currently facing multiple challenges related to an aging society, including labor shortages in various sectors, especially in agriculture. Despite government support, new farmers struggle to discern and understand market trends, changing consumer behavior, and seasonal changes. This study focuses on tomatoes and aims to assist new farmers and producers in making strategic decisions by utilizing data science techniques to understand local market consumer behavior and trends. A questionnaire survey was used to identify consumer behavior based on demographic characteristics, consumer preferences, seasonal buying and consumption behaviors, spending price per purchase, and purchasing channels. We collected 316 valid data points using a questionnaire survey deployed in face-to-face interactions across multiple locations as well as online collection methods. Data was collected from May 01, 2022, to June 30, 2022. Multiple correspondence analysis and K- means cluster analysis were used to determine six consumer segments - convenient supermarket shoppers, premium salad shoppers, price-conscious tomato enthusiasts, diverse tomato tasters, quality-conscious shoppers, and gourmet tomato shoppers. The analyses revealed the unique characteristics of tomato purchasing and consumption behaviors, including variations in tomato type, consumption type, season, demographic factors, and preferred purchasing channels. This study further explored the factors influencing tomato purchasing decisions within each segment by integrating data-driven decision-making principles. This approach allows for actionable insights facilitated by understanding local consumers while empowering new tomato farmers to make informed decisions.</p>

<p>Maize is the main staple crop in Tanzania; it is produced in almost all agroecological regions of the country, with production dominated by small-scale rain-fed farming. Maize production in Tanzania is constrained by climate change impacts such as rises in temperature, changes in rainfall patterns, and increases in plant diseases, insects, pests, floods, and droughts. Small-scale maize farmers have low climate change adaptation capacity, as the majority still use unsustainable farming practices such as monoculture, intensive tillage, and burning of crop residues, all of which increase the farmers’ vulnerability to climate change impacts. Sustainable farming practices, in particular Ecosystem-based Adaptation (EbA) practices such as the ones considered in this study, are believed to contribute significantly to restoring and conserving agroecosystems, increasing maize productivity and resilience towards climate change. This study aimed to identify the common EbA practices adopted by farmers in Tanzania and to determine the factors influencing adoption of EbA practices in maize farming. The study was conducted in the Kilosa district of the Morogoro region of Tanzania. Both primary and secondary data were used in the study. Primary data was collected through key informant interviews with the agricultural extension officers and a semi-structured questionnaire survey administered to 350 farmers. The T-test and the Tobit regression model were used for data analysis. Based on the T-test results, commonly adopted EbA practices included crop rotation, maize-legume intercropping, and improved seeds. Based on the Tobit regression analysis, farm size, household income, land ownership, access to climate information, labor, knowledge of EbA practices, and membership in the farmer field schools were found to significantly influence the adoption of EbA practices in maize farming. This study highlighted the importance of the government’s role in increasing EbA knowledge dissemination to the farmers through improving the training facilities in the farmer field schools and increasing opportunities for the farmers to have access to credit from financial service providers, allowing maize farmers to boost their income and become able to adopt more EbA practices.</p>

<p>The Japanese government established the Foreign Technical Intern and Training Program (TITP) for developing countries, enabling trainees from these countries to improve technology, skills, and practical knowledge in an actual work environment and apply their skills when they return home. However, due to issues including improper wage payments and overwork, this approach has received harsh criticism from human rights organizations inside and outside Japan. Previous research has primarily focused on the negative aspects of this program, with little emphasis placed on its positive impacts. TITP is considered critical for Indonesia because it provides high-paying jobs for “unskilled” youth, accounting for more than half of the unemployed population. This research aimed to summarize the current general condition of the TITP, classify the different programs under TITP, and compare the socio-economic conditions of the alumni after finishing TITP and returning to Indonesia. Based on the findings, we can assert that the TITP in the agriculture sector has attracted TITP alumni to pursue a career in agriculture, thereby contributing to an increase in young farmers, desperately needed to ensure the future of Indonesia’s agriculture. The majority of alumni became farmer entrepreneurs. The average income of TITP alumni working in the agriculture sector was found to be more than three times that of the average Indonesian farmer’s monthly income. The main programs realized under the TITP and reviewed in the current study included the Industrial Training Program (ITP) and the Technical Intern Program (TIP). These programs were compared with the NT Farm (NTF) in Fukui, which is recognized for its exceptional training methodology, including entrepreneurship development training. All NTF alumni now own land, and their average income is slightly higher compared to that of the ITP and TIP alumni.</p>

<p>Among new farmers, farming discontinuation within a few years is prevalent due to various issues, including difficulty in securing farmland, insufficient technology adoption, low income, and weak branding. In recent years, the importance of recruitment and support services for new farmers has been gaining recognition. Therefore, studies that can provide insights and innovations to improve the business operations and resilience of each new farmer are relevant and timely. Tomato is the most common fruit vegetable consumed fresh or processed in Japan. For new farmers, tomatoes are considered one of the favored high-value commodities for production. In response to the needs of a young female new farmer who ventured into greenhouse tomato farming in H City, Tokyo, this study aims to clarify the consumption and purchasing behavior, satisfaction and brand familiarity of randomly selected tomato consumers. We conducted a consumer survey from May to June 2022. Although we had 470 respondents, we only utilized responses from 213 consumer-respondents to capture the characteristics and preferences of those who experienced buying tomatoes from the selected farm (NF Farm). Through this case study approach, the survey revealed that supermarkets (31%) were the main place of purchase for fresh tomatoes due to convenience, followed by direct stores (28%) and unmanned stores (17%) due to both convenience and good product quality. Results indicated that cherry tomatoes were the most widely consumed across all seasons, while summer was the season with highest consumption of all tomato types, with prices ranging between 101 JPY and 500 JPY (1 USD = 133.9 JPY). After only 5 years in business, NF Farm seemed to have gained a fan base. Unfortunately, 63.8% of consumer- respondents indicated no knowledge of the farm logo. Most related the farm to the name of the farmer. Thus, there is a need for NF Farm to re-evaluate its farm brand (e.g., logo, farm name, labeling) so that it will be properly recognized even by its long-time customers.</p>

<p>In Japan, engaging in agriculture as a new farmer comes with various challenges and uncertainties. To sustain and secure the agriculture sector’s future, national and local governments, farmers, private entities, and other stakeholders provide a wide range of support. Seeking best practices is a sound basis for increasing the number of new farmers and improving their resilience. Through a case study approach, this study aimed to clarify the current condition and issues of agricultural support for new farmers in H City, Tokyo, and determine the initiatives and agricultural support that assisted a young female farmer in establishing an urban farm. This study conducted interviews with a young female farmer and city officers. The in-depth key informant interviews revealed that training, subsidies, securing land services, and referral to farmer’s organizations are some of the available forms of support. The interviewed farmer considered the recent revision of the Law on Productive Green Areas a significant opportunity for her to rent farmland, which is a challenge for most new farmers. Despite the fact that a 5-year rental period is commonly practiced, she could avail of a 30-year lease, conveying the importance for new farmers to also develop trust, confidence, and a good relationship with the farmland owner. Although the interviewed farmer has successfully established a farm, there is a need for further investigation to clarify consumer preferences, buying behavior, and their degree of familiarity with her farm and products to improve her farm business and resilience.</p>

<p>Haitian farming faces serious climate risks. Losses due to hurricanes, droughts, floods, and diseases seriously threaten productivity. This paper aimed to study the feasibility and acceptability of agricultural technology packages that could help manage risk while improving the productivity of farming in Haiti. Significant risks faced by farmers include uninsurable disasters due to their systemic and catastrophic nature. Therefore, a package of technologies including a paid-in-kind "stabilization account" component may be an appropriate financial tool for risk management. Are Haitian farmers open to such innovation? To answer this question, we collected data from 28 agricultural experts and 1,400 farmers, including 234 maize farmers in southern Haiti, and adopted the new product development (NPD) process to test the feasibility of the concept. We used the Spearman correlation, multinomial logistic regression, and linear regression to determine factors affecting the openness of Haitian farmers to innovation. We also conducted the Cochran-Mantel-Haenszel test to analyze the association between "financial inclusion" and "openness to innovation." Based on the results, 70 % of farmers expressed their willingness to pay 6 % to more than 12 % of their harvested crop as a stabilization account. Farmers with "financial inclusion" are expected to be twice as likely to adopt innovative technologies, while farm size, gender, household size, and revenue had a significant positive impact on openness to innovation. However, contrary to the trends found in literature, we found that risk aversion may positively affect the acceptance and adoption of some technologies. The results also suggest that, in Haitian farming, risks linked to natural disasters are more strongly related to financial incapacity than uncertainty. Therefore, access to proper just-in-time inputs complemented by a financial tool to overcome uncertainty will significantly boost the adaptability and resilience of Haitian farmers toward climate risks.</p>

<p>Information transfer is vital in improving knowledge and proper technology implementation, especially in agriculture. This paper aimed to describe the information system among the Pangasinan mango contractors. Specifically, it aimed to 1) identify the sources of information for the mango contractors, 2) determine information channels for information transfer, 3) establish the type of information that mango contractors prioritize, 4) determine the challenges and issues in the transfer of information, and 5) recommend interventions to improve information transfer among mango contractors. The study area is Pangasinan, Philippines, the country’s top mango-producing province. The research used a purposive sampling of 55 mango contractors covering six mango-producing municipalities. Descriptive statistics and correspondence analyses were employed in the study. Results showed that most mango contractors generally receive information on the production and marketing of mangoes from farm technicians and buyers. They usually get information on production technologies from farm technicians and other mango contractors. Expectedly, they get their information on mango marketing from their buyers. On the other hand, information transfer usually happens through mobile phones and during farmers’ meetings. Furthermore, contractors prefer to get information on the buying price of mangoes, followed by the quality requirements of buyers. Contractors also choose to have a face-to-face conversation when obtaining information. The next preference is through text and calls using mobile phones. In summary, mango contractors still prefer the traditional information system through face-to-face conversations, text, and mobile phone calls. This has implications for the implementation of modern technologies used for information dissemination. Mango contractors might not be receptive to new ways of receiving communication, even if the information might be urgent or essential. It is recommended that contractors be trained to use modern communication technologies to make them more receptive to other communication channels.</p>

Rivers are the key conduits for land-to-sea debris transport. We present in situ monitoring data of macro debris and microplastic along the supercritical Citarum River in Indonesia We identified the dams as concentrated areas of microplastic. Plastics accounted for 85% of the riverine debris (5369 ± 2320 items or 0.92 ± 0.40 tons daily). We estimated macrodebris releases of 6043 ± 567 items or 1.01 ± 0.19 tons daily with a microplastic con- centration of 3.35 ± 0.54 particles per m3 from Citarum River to sea. It has been suggested that population density and urbanization rate are major factors determining the spatiotemporal variability of macrodebris and microplastic abundances in the Citarum River. Our research highlights the importance of long-term monitoring to estimate debris and microplastics inflows along the Indonesian river to the world ocean as a benchmark for the reduction of macro and microdebris into the environment.

<p>Past studies have found that boosting agriculture entrepreneurship education for the youth is one of the critical solutions to the aging agricultural population. Agriculture stakeholders need to provide entrepreneurship training to youth early to develop more agribusiness opportunities and strengthen their entrepreneurial competencies. This paper aims to provide an overview of the development of agriculture entrepreneurship research in the context of youth can become a basis for researchers to conduct future studies on the related topic. This paper reveals the general trend of the subject studied, objectives, methodologies, and research finding through an extensive systematic literature review of past studies on this topic conducted between 2000 to 2021. Out of the total of 1,492 papers found using a combination of the words "Agriculture, " "Entrepreneurship, " and "Youth, " 62 articles passed the screening criteria and were analyzed for this research. This study found that 27 % of the reviewed studies focus on university and college students. More than 32 % of the studies' objective was to identify the factors influencing youth inclination and intention towards agripreneurship. Subjective norms (external factors) were the determining factors that affect the intention in agripreneurship. Around 39 % of the studies used Likert scale questionnaires to obtain data, and more than 55 % analyzed the data using qualitative descriptive analysis, 24 % used multiple linear regression, and 15 % used Theory of Planned Behavior. This paper highlights the need for agripreneurship studies on young farmers using more variative analysis methods to obtain a broader understanding.</p>

<p>In Tanzania, tea is considered as one of the most exported crops. The main stakeholders of the tea industry are smallholder farmers and estates. Smallholder tea farmers are required to engage in contract farming, as stipulated in the Tea Regulation of 2010. This study attempted to assess contract farming and its impact to production and income of tea smallholder farmers in Rungwe District, Tanzania. A total of 48 randomly selected smallholder farmers were interviewed using a semi-structured questionnaire in September 2020 and October 2021. Agribusiness company officials, government officials and extension officers were also interviewed to clarify the condition and issues of the contract farming scheme. Descriptive analysis and cost and return analysis were utilized. Results show that yield, income, and profitability increased from 2016-2019. These can be attributed to steady supply of inputs, easy access to technical assistance, and early adoption of new technology under contract farming scheme. Moreover, the price of smallholder green leaf has improved, with farmers receiving a second payment hence improve their overall revenue returns.</p>
