    农业,人类文明的基石,面临气候变化带来的日益严峻的挑战,资源限制,和停滞不前的收益率。精确的作物产量预测对于制定贸易政策至关重要,发展战略,人道主义倡议。本研究引入了一个全面的机器学习框架,旨在预测作物产量。我们在适度碳排放情景下利用CMIP5气候预测来评估农业用地的未来适宜性,并纳入气候数据,历史农业趋势,和化肥用量对项目产量的影响。我们的综合方法预测到2028年东南亚作物产量的显着区域变化,确定潜在的耕地利用。具体来说,印度尼西亚的农田面积,马来西亚,菲律宾,如果不采取行动,越南预计将下降10%以上,并且有可能减轻这种损失。此外,越南的大米产量预计将下降19%,泰国将下降7%,而菲律宾可能会看到与2021年相比5%的增长。我们的发现强调了气候变化和人类活动对农业生产力的关键影响,为决策和促进国际合作提供必要的见解。
    Agriculture, a cornerstone of human civilization, faces rising challenges from climate change, resource limitations, and stagnating yields. Precise crop production forecasts are crucial for shaping trade policies, development strategies, and humanitarian initiatives. This study introduces a comprehensive machine learning framework designed to predict crop production. We leverage CMIP5 climate projections under a moderate carbon emission scenario to evaluate the future suitability of agricultural lands and incorporate climatic data, historical agricultural trends, and fertilizer usage to project yield changes. Our integrated approach forecasts significant regional variations in crop production across Southeast Asia by 2028, identifying potential cropland utilization. Specifically, the cropland area in Indonesia, Malaysia, Philippines, and Viet Nam is projected to decline by more than 10% if no action is taken, and there is potential to mitigate that loss. Moreover, rice production is projected to decline by 19% in Viet Nam and 7% in Thailand, while the Philippines may see a 5% increase compared to 2021 levels. Our findings underscore the critical impacts of climate change and human activities on agricultural productivity, offering essential insights for policy-making and fostering international cooperation.

    灌溉发展,特别是小规模灌溉,是提高一个国家农村社区农业生产力的最重要项目之一。小规模灌溉改善埃塞俄比亚农村地区家庭生计的程度尚未得到广泛认可。因此,将寻求关于小规模灌溉对Legehida地区农民生计影响的研究。这项研究采取了“有”和“没有”的策略,比较使用灌溉的农民和不使用灌溉的农民。为了进行分析,采用了定量和定性数据.调查的受访者是使用随机抽样方法从灌溉用户和非用户家庭中选择的。该研究的定量数据是从随机选择的241户农户中收集的,其中113个是用户,128个是非用户,使用半结构化问卷。因此,倾向得分匹配模型被用来检验小规模灌溉对农民生计的影响。Logit模型结果表明,耕地规模,非农收入,教育水平,家庭大小,抚养比,总牲畜单位,与最近的农业推广办公室/FTC的距离是决定在其他因素保持不变时是否实行灌溉的决定性因素。使用倾向评分匹配模型评估灌溉对家庭收入和粮食安全(每日卡路里摄入量)的影响。结果表明,对使用小规模灌溉的农民的积极和显着影响使家庭的每日热量摄入量和年收入增加了244.162千卡和5234.258ETB,分别,与非灌溉用户相比。这表明,参加小规模灌溉活动的家庭的年收入和粮食安全状况高于可比群体。总的来说,该研究建议减少粮食不安全和农村家庭的社会经济问题,灌溉农业是可行的解决方案之一;因此,政府和非政府组织应广泛关注小型灌溉基础设施的建设,政策,战略,和扩展服务,以提高生产力,收入,和改善农村家庭的生活。
    Irrigation development, particularly small-scale irrigation, is one of the most important projects for improving agricultural productivity in a country\'s rural communities. The extent to which small-scale irrigation has improved household livelihoods in Ethiopia\'s rural areas is not widely recognized. As a result, research on the influence of small-scale irrigation on farmers\' livelihoods in the Legehida district will be sought. The study took a \"with\" and \"without\" strategy, comparing farmers who used irrigation against those who did not. For analysis, both quantitative and qualitative data were employed. The survey\'s respondents were chosen using a random sample approach from both irrigation users and nonuser households. Quantitative data for the study were collected from randomly selected 241 farm households, of which 113 were users and 128 were nonusers, using a semistructured questionnaire. Accordingly, the propensity score matching model was employed to examine the impacts of small-scale irrigation on farmers\' livelihoods. The logit model result indicates that cultivated land size, off-farm income, education level, family size, dependency ratio, total livestock unit, and distance to the nearest agricultural extension office/FTC are determinant factors in determining whether to practice irrigation when other factors remain constant. The impact of irrigation on a household\'s income and food security (in terms of daily calorie intake) was evaluated using a propensity score matching model. The result shows that a positive and significant impact on farmers who use small-scale irrigation has increased the daily calorie intake and annual income of households by 244.162 kilocalories and 5234.258 ETB, respectively, as compared to nonirrigation users. This shows that households that participate in small-scale irrigation activities have a higher annual income and food security status than comparable groups. In general, the study recommends that to reduce food insecurity and the socioeconomic problems of rural households, irrigation farming is one of the viable solutions; therefore, the government and nongovernmental organizations should extensively focus on the enhancement of small-scale irrigation infrastructure, policies, strategies, and extension services to increase productivity, income, and livelihood improvement in rural households.

    随着城市化和工业化进程的不断推进,农田非谷物生产(NGPCL)逐渐变得越来越普遍。这一现象将压缩粮食生产空间,引发全球粮食危机。如何科学认识和有效控制NGPCL已成为一个科学问题。这项研究,在地块尺度上进行,建立了NGPCL的测量指标,并进一步探讨了山区NGPCL的特点和驱动机制。结果表明:(1)与粮食种植地块相比,非谷物生产的地块往往更加分散,梯田表现出最显著的分散,而平原的聚集程度最高。(2)在灌溉条件方面,灌溉土地和旱地更有可能进行NGPCL。就地形而言,坡耕地用于NGPCL的可能性最高。(3)坡度较大的区域,海拔较高,与沉降的高度差异更大,距离定居点和道路更远,更靠近森林,更有可能参与NGPCL。(4)不同的地块特征对NGPCL的影响不同。地块特征主要影响粮食生产成本和收益,推动农民改变生产模式,引发NGPCL。
    With the continuous advancement of urbanization and industrialization, non-grain production on cropland (NGPCL) is gradually becoming more widespread. This phenomenon will compress the space for grain production and trigger a global food crisis. How to scientifically understand and effectively control NGPCL has become a scientific issue. This study, conducted at the plot scale, establishes a measurement index for NGPCL and further explores the characteristics and driving mechanisms of NGPCL in mountainous areas. The results indicate the following: (1) Compared to plots for food-growing, plots for non-grain production tend to be more dispersed, with terraces showing the most significant dispersion, while plains exhibit the highest degree of aggregation. (2) In terms of irrigation conditions, irrigated land and dry land are more likely to undergo NGPCL. In terms of topography, slope croplands have the highest probability of being used for NGPCL. (3) Regions with steeper slopes, higher elevations, greater differences in altitude from the settlement, farther distances from settlements and roads, yet closer proximity to forests, are more likely to engage in NGPCL. (4) Different plot characteristics have varying impacts on NGPCL. Plot characteristics primarily affect the costs and returns of grain production, driving farmers to change their production patterns and triggering NGPCL.

    粮食捐赠已在全球范围内扩展,并已成为新兴国家普遍的粮食援助形式。然而,在这些环境中对食物捐赠经验的研究仍然很少。
    在这种情况下,当前工作的目标如下:(i)探讨乌拉圭利益相关者对粮食捐赠作为减少粮食浪费的战略的看法,(ii)确定乌拉圭粮食捐赠的障碍和推动者,和(iii)探讨乌拉圭食品银行的组织特征。
    采用了基于两种数据收集策略的定性方法:对官方政府文件进行文献内容分析,并对乌拉圭与食物浪费和食物捐赠有关的主要利益相关者进行深入的半结构化访谈。
    在乌拉圭利益相关者看来,食品捐赠已成为减少食物浪费的核心战略,主要是因为它被认为是减少粮食不安全的有效策略。乌拉圭利益攸关方承认粮食捐赠的复杂性,并确定了与经济考虑相关的几个实施障碍,捐赠产品的特点,法律和商业考虑,和食品银行的组织特征。
    尽管大多数障碍与以前在发达国家进行的研究结果一致,还确定了乌拉圭背景的一些特殊性。明确和详细的法律框架,以确保捐赠的产品到达目标人群,以及对捐赠食品的营养要求被认为是必要的。
    UNASSIGNED: Food donation has expanded globally and has become a common form of food assistance in emerging countries. However, research on food donation experiences in these settings is still scarce.
    UNASSIGNED: In this context, the objectives of the present work were as follows: (i) to explore the views of Uruguayan stakeholders on food donation as a strategy to reduce food waste, (ii) to identify barriers and enablers for food donation in Uruguay, and (iii) to explore the organizational characteristics of Uruguayan food banks.
    UNASSIGNED: A qualitative approach based on two data collection strategies was used: documentary content analysis of official governmental documents and in-depth semi-structured interviews with key stakeholders related to food waste and food donations in Uruguay.
    UNASSIGNED: Food donation emerged as a central strategy for food waste reduction in the view of Uruguayan stakeholders, mainly because it was perceived as an efficient strategy to reduce food insecurity. The complexity of food donation was acknowledged by Uruguayan stakeholders and who identified several barriers for its implementation related to economic considerations, the characteristics of the donated products, legal and commercial considerations, and organizational characteristics of food banks.
    UNASSIGNED: Although most barriers were aligned with results from previous studies conducted in developed countries, some specificities to the Uruguayan context were also identified. Clear and detailed legal frameworks to ensure that the donated products reach the target population along with nutritional requirements for the foods to be donated were deemed necessary.

    猴面包树(AdansoniadigitataL.)是撒哈拉以南非洲许多旱地农业系统的组成部分。这种传统的农林业系统可以带来各种好处;除了积极的生计影响外,猴面包树由于其高营养的水果而特别能解决粮食安全目标。然而,许多瓶颈仍然存在,阻碍了土著树木在耕作系统中的更广泛潜力,以及它们的更多利用和商业化。我们建议,通过刺激当地猴面包树产品市场的出现,同时促进旨在满足不断出现的市场需求的业务和创新,可以推进具有猴面包树的传统农业系统。提高当地农林业产品的感知价值,同时促进更多的商业化途径,反过来又会带来粮食安全和生计效益。采用多方利益相关者的方法,这些考虑因素在基利菲付诸实践,肯尼亚,通过发起以社区为基础的企业发展,生产高质量的猴面包树粉和油。初步结果显示行为改变,关于猴面包树管理和利用的改进的实用技术,猴面包树的消费量增加,这可能已经有助于实现粮食安全目标。猴面包树越来越被视为一种宝贵的资源,而不是“穷人的食物”和邪恶的灵魂所拥有的树。这可能为社区的进一步增值活动和企业发展奠定基础。猴面包树很常见,然而到目前为止,基利菲当地农业系统的未充分利用特征,基于其日益商业化的活动可以是互补的,并且很容易整合到现行的生计策略中。
    The baobab tree (Adansonia digitata L.) is an integral component of many dryland farming systems in sub-Sahara Africa. Such traditional agroforestry systems can foster a variety of benefits; besides positive livelihood implications baobab can particularly address food security objectives due to its highly nutritious fruits. However, many bottlenecks persist inhibiting the broader potential of indigenous trees in farming systems and their increased utilisation and commercialisation. We suggest that traditional farming systems with baobab trees can be advanced by stimulating the emergence of local markets for baobab products while promoting businesses and innovations aimed at meeting the arising market demand. Increasing the perceived value of local agroforestry products in combination with facilitating additional commercialisation pathways will in turn lead to food security and livelihood benefits. Using a multi-stakeholder approach such considerations were put into practice in Kilifi, Kenya, by initiating a community-based enterprise development producing high-quality baobab powder and oil. Initial results demonstrate behavioural changes, an improved practical knowhow with regard to baobab management and utilisation, and an increased consumption of baobab, which may already contribute to food security objectives. Baobab is increasingly seen as a valuable resource as opposed to \'food for the poor\' and a tree possessed by evil spirits. This may lay the groundwork for further value addition activities and enterprise development in the communities. With baobab being a common, yet so far underutilised feature of local farming systems in Kilifi, activities based on its increasing commercialisation can be complementary and easily integrable to prevailing livelihood strategies.

    BACKGROUND: Health care-based food assistance programs show promise but are underutilized. Strict eligibility requirements and program scheduling may dampen reach and outcomes.
    OBJECTIVE: To explore factors associated with uptake of a health center-based mobile produce market with no eligibility requirements and few barriers to entry.
    METHODS: A cross-sectional analysis of medical record, sociodemographic, environmental, and market attendance data was used.
    METHODS: The study sample consisted of 3071 adults (18+ years) who were patients of an urban health center in eastern Massachusetts and registered for the mobile market during the study period of August 2016 to February 2020.
    METHODS: The main outcome measure was monthly market attendance over the study period.
    METHODS: T-tests and χ2 tests were used to compare market users and never-users. Multiple logistic regression was used to analyze variables associated with market attendance each month.
    RESULTS: In multiple variable analyses, Supplemental Nutrition Assistance Program enrollment was associated with slightly less frequent monthly market use (odds ratio [OR], 0.989; 95% CI, 0.984-0.994). Day-of, on-site market registration was associated with more frequent monthly use than self-registration on nonmarket days (OR, 1.08; 95% CI, 1.07-1.08). Having a psychiatric or substance use disorder diagnosis was associated with slightly less frequent market attendance (OR, 0.99; 95% CI, 0.98-0.99; and OR, 0.96; 95% CI, 0.95-0.97, respectively) compared with registrants without these diagnoses.
    CONCLUSIONS: Individual, community-level, and organizational factors are associated with uptake of a free mobile produce market and should be considered when designing programs.

    粮食安全是一个具有不断演变的定义和含义的概念,由有争议的知识和不断变化的环境塑造。政府对粮食安全的理解方式会影响公共政策如何解决这一问题。这项研究调查了1994年至2023年塔斯马尼亚食品和营养政策中话语和实践的演变。使用定性文档分析对四个基础文档进行了分析,揭示了三十年来持续存在的粮食不安全问题。该分析确定了解决营养相关健康问题和粮食不安全的持续政策挑战的双重性:促进公共卫生改善和保护塔斯马尼亚经济之间的平衡行为。研究表明,从1994年到2023年,塔斯马尼亚的食品和营养政策和战略具有各种转变和紧张的特点。传统方法,主要强调粮食供应,在有限的程度上,access,坚持了三十多年。向更现代的粮食安全方法过渡,结合使用的尺寸,稳定性,可持续性和机构,明显缓慢,表明系统惯性。这表明未来政策演变的机会,走向动态和全面的方法。这种方法将超越粮食供应的狭隘重点,解决粮食安全的复杂多层面性质。
    Food security is a concept with evolving definitions and meanings, shaped by contested knowledge and changing contexts. The way in which food security is understood by governments impacts how it is addressed in public policy. This research investigates the evolution of discourses and practices in Tasmanian food and nutrition policies from 1994 to 2023. Four foundational documents were analysed using qualitative document analysis, revealing persistent food insecurity issues over three decades. The analysis identified a duality in addressing the persistent policy challenges of nutrition-related health issues and food insecurity: the balancing act between advancing public health improvements and safeguarding Tasmania\'s economy. The research revealed that from 1994 to 2023, Tasmania\'s food and nutrition policies and strategies have been characterised by various transitions and tensions. Traditional approaches, predominantly emphasising food availability and, to a limited extent, access, have persisted for over thirty years. The transition towards a more contemporary approach to food security, incorporating dimensions of utilisation, stability, sustainability, and agency, has been markedly slow, indicating systemic inertia. This points to an opportunity for future policy evolution, to move towards a dynamic and comprehensive approach. Such an approach would move beyond the narrow focus of food availability to address the complex multi-dimensional nature of food security.

    家庭粮食安全,喂养实践,饮食多样性和家庭粮食不安全的应对策略在很大程度上是相互关联的。使用横断面研究方法,涉及乌干达北部科尔区0-36个月大的儿童的162名母亲和护理人员,这项研究调查了家庭粮食安全状况,儿童饮食多样性与家庭应对策略。研究表明,尽管儿童饮食多样性水平较低,但大多数家庭(55%)都有粮食安全(6-23个月大的儿童为68.1%,24-36个月大的儿童为55.3%)。我们发现来自谷物的淀粉食品,根和块茎是儿童喂养中最主要的食物组(82%),由于其他必需食物类别的消费有限,尤其是水果,蔬菜,肉类和乳制品(合计18%)。此外,只有57%的0至6个月大的儿童接受纯母乳喂养,补充食品的引入往往被推迟,并且对6个月以上的人没有很好的计划。结果还表明,采用了广泛的应对策略,但主要的策略是,对不太喜欢的食物的依赖(54.9%),限制膳食部分(35.2%),减少一天的进餐次数(29%),采集野生水果和收获未成熟作物(29.6%)。据观察,家庭粮食安全是儿童饮食多样性的重要决定因素,当家庭遇到粮食不安全时,可能会影响喂养方式和适用于家庭的应对策略范围。此外,营养教育,家庭规模和生计多样性在决定家庭粮食安全状况方面发挥着重要作用,儿童饮食多样性和应对农村家庭粮食不安全问题。总之,解决家庭粮食安全问题,和应对策略可以在改善农村社区儿童喂养方式和饮食多样性方面发挥重要作用。
    Household food security, feeding practices, dietary diversity and coping strategies to household food insecurity are largely interconnected. Using a cross sectional study approach involving 162 mothers and care givers of children 0-36 months of age in Kole district of northern Uganda, this study examined the household food security status, child dietary diversity and household coping strategies. The study revealed that a slight majority of the households (55%) were food secure although with a low level of child dietary diversity experienced (68.1% for children 6-23 months age group and 55.3% for 24-36 months age group). We found that starch-based foods derived from cereals, roots and tubers were the most predominantly used food group in child feeding (82%), with limited consumption of other essential food groups, notably fruits, vegetables, meats and dairy products (18% combined). Additionally, only 57% of children 0 to 6 months old were receiving exclusive breastfeeding, and the introduction of complementary foods is often delayed and not well planned for those above 6 months of age. Results also showed that a wide range of coping strategies are employed however the major ones were, reliance on less preferred food (54.9%), limiting portions of meals (35.2%), reducing number of meals taken in a day (29%), and gathering wild fruits and harvesting immature crops (29.6%). It was observed that household food security is a strong determinant of child dietary diversity, may influence feeding practices and the range of coping strategies applicable to households when they experience food insecurity. Furthermore, nutritional education, household size and livelihood diversity play a significant role in determining household food security status, child dietary diversity and coping with food insecurity within rural households. In conclusion, addressing household food security, and coping strategies can play an important role in improving child feeding practices and dietary diversity in rural communities.

    一场重大的全球灾难可能会破坏液体燃料贸易。依赖进口石油产品的国家可能难以维持工业化农业。进口100%精炼燃料的岛国尤其脆弱。我们的案例研究旨在估算在没有贸易的情况下养活新西兰人口所需的农业用地面积和生物燃料量。结果表明,储存的柴油在正常使用(数周)甚至严格配给(数月)时会很快耗尽。为了保存燃料,我们发现,在气候照常的情况下,种植小麦(每年只需要540万升[L]柴油)比土豆(12.3)或乳制品(38.7)更省油,以养活全国人口。在核冬天的情况下,随着农业产量的下降,需要按比例增加柴油。小麦将需要目前24%的谷物种植土地,并且用作所需生物燃料原料的油菜作物将再占据1%-7%。对油菜生物柴油或可再生柴油精炼厂的投资可以确保最低农业液体燃料需求的供应。随后的分析支持这一选择,作为燃料弹性反应的一部分,并作为日常食品使用的权衡,可以通过市场机制鼓励在灾难发生前扩大炼油和油菜种植,政府直接投资,或者这些的组合。生物燃料精炼的物流规模扩大,灾难后,也应该进行分析。Further,正常生产的生物柴油将有助于该国实现其减排目标。其他国家也应进行类似的分析。
    A major global catastrophe would likely disrupt trade in liquid fuels. Countries dependent on imported oil products might struggle to sustain industrial agriculture. Island nations importing 100% of refined fuels are particularly vulnerable. Our case study aimed to estimate the agricultural land area and biofuel volumes needed to feed the population of New Zealand in the absence of trade. Results showed that stored diesel would quickly be exhausted with ordinary use (weeks) and even with strict rationing (months). To preserve fuel, we found that farming wheat (requiring as little as 5.4 million liters [L] of diesel per annum) was more fuel-efficient than potatoes (12.3) or dairy (38.7) to feed the national population under a climate-as-usual scenario. In a nuclear winter scenario, with reduced agricultural yields, proportionately greater diesel is needed. The wheat would require 24% of current grain-cropped land, and the canola crop used as feedstock for the required biofuel would occupy a further 1%-7%. Investment in canola biodiesel or renewable diesel refineries could ensure supply for the bare minimum agricultural liquid fuel needs. Were subsequent analysis to favor this option as part of a fuels resilience response and as a tradeoff for routine food use, expansion in refining and canola cropping before a catastrophe could be encouraged through market mechanisms, direct government investment, or a combination of these. Logistics of biofuel refining scale-up, post-catastrophe, should also be analyzed. Further, biodiesel produced in normal times would help the nation meet its emissions reduction targets. Other countries should conduct similar analyses.

    COVID-19大流行影响了全球农业食品系统。然而,虽然不同国家/地区的影响不同,学术文献似乎集中在全球北方的发达国家。因此,这篇综述仔细研究了有关大流行对近东和北非(NENA)地区影响的文献。2023年3月在WebofScience上的搜索生成了334个文档,其中151人符合纳入系统审查的条件。根据文献计量分析,最活跃的国家是沙特阿拉伯,埃及,乔丹,阿拉伯联合酋长国,和黎巴嫩。总的来说,海湾地区的研究覆盖率要好于北非欠发达国家和遭受战争的国家(参见利比亚,叙利亚,和也门)。研究通常集中在作物生产和下游食物链上(参见分配和消费)。虽然这场流行病影响了粮食安全的每一个支柱,这项研究集中在获取和利用上。同时,大部分文献涉及大流行的社会经济影响,特别是那些与食品安全和健康有关的。大流行,暴露了农业食品系统的脆弱性,应该抓住这一机会,以促进NENA地区向更具弹性的农业食品系统的过渡。
    The COVID-19 pandemic affected agri-food systems worldwide. However, while the impacts differed from one country/region to another, the scholarly literature seems to focus on developed countries in the Global North. Consequently, this review scrutinizes the literature on the pandemic\'s impacts in the Near East and North Africa (NENA) region. A search on the Web of Science in March 2023 generated 334 documents, of which 151 were eligible for inclusion in the systematic review. According to the bibliometric analysis, the most active nations are Saudi Arabia, Egypt, Jordan, the United Arab Emirates, and Lebanon. In general, the coverage of studies is better in the Gulf region than in the less developed countries of North Africa and those suffering from wars (cf. Libya, Syria, and Yemen). Studies generally focus on crop production and the downstream food chain (cf. distribution and consumption). While the pandemic influenced every pillar of food security, this research concentrates on access and utilization. Meanwhile, the lion\'s share of the literature deals with the pandemic\'s socio-economic effects, especially those linked to food (in)security and health. The pandemic, which laid bare the agri-food system vulnerabilities, should be seized to foster the transition towards more resilient agri-food systems in the NENA region.
