For Chinese government, designing appropriate subsidy policies to mobilize chain members’ reduction effort about agricultural pollution emission (hereafter, PE) and grain post-harvest loss (hereafter, GPHL) is an urgent problem to be solved. Therefore, a grain supply chain with one producer, one retailer and government were chosen as our study subject. We proposed concepts and function expressions of stakeholders’ reduction efforts on PE and GPHL, and the demand function was modified. Four investment and subsidy models were analyzed. Findings: 1) stakeholders’ reduction efforts about GPHL and PE are positively related to their incomes. In the future, government can try to subsidize chain members’ reduction efforts on GPHL and PE. 2) Within a certain range, the government’s variable subsidy will motivate the producer and the retailer to reduce their PE and GPHL, otherwise, the government should adopt a fixed subsidy. 3) No matter whether supply chain members invest in GPHL reduction technology or not, both the equilibrium prices and revenues of stakeholders have a positive relationship with the effort level of PE reduction.

This cross-sectional research assessed nutrition knowledge in a sample of college students in Amman, Jordan and its association with food security and other risk factors. An Arabic Nutrition Knowledge Index (ANKI) was developed and validated in 122 college students (pilot study). In the replication study, the demographics scale, validated ANKI, and Arabic Individual Food Insecurity Experience Scale (FIES) were administered to 470 students. The ANKI was reliable (Cα = 0.82) and stable over time (ICC = 0.82, P < 0.001; paired t-test P = 0.57). Mean ANKI score was good for the pilot study (19.52±0.48) and replication study (19.68 ± 0.22). In the replication study, mean ANKI score was significantly larger among food secure (20.07 ± 0.23) than among moderately (18.28 ± 0.63) and severely food insecure students (14.22 ± 0.70) (F = 11.87, P = 0.000). Thus, measuring nutrition knowledge using the ANKI would provide baseline data for researchers and policy-makers to develop dietary guidelines for Jordanians. Finally, interventions are needed to raise nutrition awareness among college students, to maintain a healthy lifestyle.
这项横断面研究评估了约旦安曼大学生样本的营养知识及其与粮食安全和其他风险因素的关系。建立了阿拉伯语营养知识指数(ANKI)，并在122名大学生中进行了验证(试点研究)。在重复研究中，对470名学生实施人口统计学量表、经验证的ANKI和阿拉伯个人食品不安全体验量表(FIES)。ANKI是可靠的(Cα = 0.82)，且随时间稳定(ICC = 0.82, P < 0.001;配对t检验P = 0.57)。初步研究的ANKI平均评分为19.52±0.48，重复研究的ANKI平均评分为19.68±0.22。在重复研究中，食物安全学生的ANKI平均分(20.07±0.23)显著高于食物安全学生(18.28±0.63)和食物安全学生(14.22±0.70)(F = 11.87, P = 0.000)。因此，利用ANKI测量营养知识将为研究人员和政策制定者制定约旦人的饮食指南提供基线数据。最后，需要采取干预措施提高大学生的营养意识，保持健康的生活方式。

This study explored the average price series of two meat products (beef and mutton) sold at retail markets in five countries worldwide using monthly data from 2016 to 2020. The study applied the standard TAR and its extensions (CTAR and CMTAR) models to assess the speed of price movement and nature of market integration of foreign and domestic beef and mutton markets in Ghana. Due to evidence of asymmetries in the cointegration analysis among these beef and mutton market pairs, the asymmetric error correction framework was used to analyse the short-run price adjustment process. All the markets are exhibiting asymmetry processes to indicate that price movements in the foreign markets are quickly transferred to the domestic markets at different levels. The beef market pair of South Africa and Ghana exhibited threshold and asymmetric adjustment, and therefore, price change in the reference market (South Africa) must exceed the threshold price before an adjustment could occur in the Ghanaian beef market. However, there is no evidence to conclude that instability or volatility of the exogenous variables such as oil prices and exchange rates has any significant impact on the price transmission process, especially beef and mutton prices in the country. For symmetric price transmission across these markets, which indicates market efficiency, a properly functioning agricultural market information system is recommended, especially for foreign markets and domestic markets, to promote price information flow to market agents across these markets.

This study evaluated the feed value of sugarcane filter cake (SFC) for broilers. A total of 336 one-day-old Cobb500 were randomly allotted to seven treatments (T) with three replications. A diet without SFC (T0, control) was formulated for the starter (1–14 days), grower (15–28 days) and finisher (29–49 days) phases. The test diets contained sun-dried SFC at two levels (5% and 10%) and varied with feeding periods [(5%SFC (T1)- and 10%SFC-based diets (T2) for the entire period, 5%SFC (T3)- and 10%SFC-based diets (T4) for grower to finisher phases and 5%SFC (T5)- and 10%SFC-based diets (T6) for finisher phase]. Feed intake (FI), final body weight (FBW), total body weight gain (TBWG) and feed conversion ratios (FCR) were not affected (P > 0.05) at the starter phase. However, FI and ADG on 10%SFC diets were reduced (P < 0.05) at the grower phase. ADG and FBW (P < 0.05) were higher for the 10%SFC diet at the finisher phase. No performance differences (P > 0.05) were observed for the finisher and entire periods on 5%SFC-based diets. The overall FI, ADG and FCR did not vary among treatments (P > 0.05) however, TBWG was highest in T5 and T6. The overall feed consumption ranged from 3.86–4.26 kg/bird (P > 0.05). Treatments did not differ in dressed and eviscerated carcasses, cut parts, visceral organs and meat-to-bone ratios (P > 0.05). The 5%SFC- and 10%SFC-based diets resulted in higher net income. In conclusion, up to 10%SFC inclusion in the broiler diet for the whole period or at the finisher phase increases performances and economic benefit.

This study aims to analyze the short and long-term transmission of rice prices at the farmer and consumer levels in West Java Province. This study uses monthly data on rice prices at the producer (farmer) and consumer levels from 2014–2020 in West Java Province, Indonesia. Meanwhile, the method used in this study is Error Correction Model regression. The results show the existence of market integration and asymmetry in the vertical transmission of rice prices between farmers and consumers, both in the short and long term. The causes of asymmetric price transmission are the presence of uncompetitive behavior or abuse of market power among intermediary traders, especially in concentrated markets, as well as adjustment costs and menu costs. Therefore, the government needs to monitor rice prices regularly to ensure consumer affordability and profitability for farmers. In addition, the government must also have accurate information to identify irregularities or abuse of market power. Furthermore, the government needs to create policies encouraging the involvement of regionally-owned enterprises, the central government, and the private sector in the rice trading sector.

Use of farmlands for food production is under pressure and providing food for a growing population is a global concern due to alternative land use and degradation, pest infestations, urbanization and industrialization which led to climate change and encroaches arable land; especially in drylands where water, fertilizer, land, and other farm input resources are scares and needs to be utilized efficiently to enhance crop yields. Soilless culture technology reduces the challenges facing in soil-based farming which could lower yields. Improving food production and access could be possible using soilless culture. However, limited and incomplete information is available to indicate the role of soilless culture in reducing land pressure and degradation in drylands. This review aimed to examine the role of soilless culture as climate change occurs to transform dryland vegetable farming, reduce land pressure and degradation. Data gathered from relevant and recently published peer-reviewed papers and converted into uniform measurement units, paraphrased, and discussed. Studies indicated that soilless culture efficiently uses water, fertilizer, and land by 90, 70 and 75%, respectively, with average yield advantage of 147.3 t. ha−1 over soil-based farming. Soilless culture avoids soil disturbance and reduces land pressure and degradation while promoting crop intensification through year-round production. It supports soil-based farming, minimizes the negative impacts of agrochemicals on the environment, mitigates climate change, and increases productivity in drylands. It is economically feasible, environmentally sound, and socially accepted.
用于粮食生产的农田受到压力，为不断增长的人口提供粮食是一个全球关注的问题，原因是替代土地利用和退化、虫害、城市化和工业化导致气候变化和侵占耕地;特别是在干旱地区，水、肥料、土地和其他农业投入资源稀缺，需要有效利用以提高作物产量。无土栽培技术减少了土壤农业面临的可能降低产量的挑战。利用无土栽培可以改善粮食生产和获取。然而，表明无土栽培在减少旱地土地压力和退化方面的作用的资料有限且不完整。本文旨在探讨气候变化下无土栽培在改变旱地蔬菜种植、减少土地压力和退化方面的作用。从相关和最近发表的同行评议论文中收集的数据，并转换为统一的测量单位，解释和讨论。研究表明，无土栽培对水、肥和土地的有效利用率分别为90%、70%和75%，平均产量比土壤耕作高147.3 t. ha−1。无土栽培避免了土壤扰动，减少了土地压力和退化，同时通过全年生产促进作物集约化。它支持土壤农业，最大限度地减少农用化学品对环境的负面影响，减缓气候变化，并提高旱地的生产力。它在经济上可行，对环境无害，并为社会所接受。

Low nutrient availability in sandy soils is a serious threat to crop productivity. The present study evaluated the effectiveness of cotton-sticks biochar, sugarcane press-mud, and vegetable compost on soil chemical properties and chickpea yield in sandy soils. Two chickpea varieties, Bittal-2016 and Noor-2019, were grown in soil amended with cotton-sticks biochar at 10 and 15 Mg ha−1; sugarcane press-mud at 10 and 15 Mg ha−1; vegetable compost at 10 and 15 Mg ha−1; cotton-sticks biochar at 10 and 15 Mg ha−1 plus loaded with Fe/Zn including no amendment. Cotton-sticks biochar at 15 Mg ha−1 loaded with Fe/Zn significantly increased chlorophyll (48.40), N (3.1, 2.5, and 3.9%), P (1.13%, 1.10, and 1.4%), and K (1.44, 2.26, and 1.27%) in root, shoot, and grains of var. Noor-2019. Soil amended with vegetable compost at 10 Mg ha−1 and Fe/Zn-loaded biochar at 15 Mg ha−1 exhibited a marked increase in shoot length (43.2 cm), root length (25.8 cm), root fresh weight (8.0 g), pods per plant (34), 100-grain weight (32.7 g), and grain yield (25.9 g) for var. Noor-2019. Amended soil with Fe/Zn-loaded biochar at 10 Mg ha−1 depicted a remarkable increase in soil EC, pH, OM, and N by 2.12 dS m−1, 8.4, 0.67% and 0.20%, respectively. Conclusively, Fe/Zn-loaded cotton-sticks biochar at 15 Mg ha−1 and vegetable compost at 10 Mg ha−1 effectively improved the soil chemical properties, nutrient uptake, and yield of var. Noor-2019. Hence, cotton-sticks biochar could be used as eco-friendly approach for improving chickpea production in coarse-textured soils.

The planting industry plays a significant role as both a source of global greenhouse gas emissions and a carbon sink system. It is crucial to clarify the carbon sources and sinks of the planting industry for the development of low-carbon agriculture. This study calculates the carbon sources and sinks of the planting industry based on crop data from 2000 to 2020 and utilizes the Theil index for further analysis. The results indicate that the total carbon sources of the planting industry in China initially increased and then decreased, ranging from 75.71 million tons to 98.22 million tons, with an average annual growth rate of 2.06%. On the other hand, the carbon sinks of the planting industry increased from 563.805 million tons to 864.42 million tons, reflecting a 53.32% increase. Notably, the national net carbon sinks demonstrated a steady growth trend, rising from 488.10 million tons in 2000 to 766.21 million tons in 2020. Secondly, the differences of carbon sources and sinks have increased and the distribution differences were basically differences within regions. Thirdly, with regionally unbalanced distribution, there were obvious differences in the variation of regional net carbon sinks. Guangxi had the highest level of net carbon sinks. Consequently, the development of a low-carbon planting industry necessitates reduced reliance on agricultural inputs and the formulation of region-specific agricultural carbon reduction policies. It also involves exploring the potential for agricultural carbon reduction in each region, promoting regional cooperation, and improving the mechanism for dividing regional tasks.

Biofortified foods are smart and strategic nutritious foods which plays critical role in addressing global burden of micronutrients in many emerging economies. While there is more and more consensus about the potential benefits of biofortification, the challenge lies on how to scale up its consumption and market system. This requires understanding of the dynamics of the biofortified cassava consumer demand and producers supply. Therefore, the study aims to identify the demand and supply drivers for biofortified foods and how it affects the food security of households across Nigeria.. A survey was administered to 240 willing consumers and 90 producers of biofortified cassava. The results revealed that price, marketing orientation, institutional support, price of substitute and education had a significant influence on supply, while the price of substitute, expenses on nutritional products, awareness of benefits, income, recommendation from experts, and education had a significant impact on demand for biofortified cassava. Our study lends support to the important role of communication to improve awareness and increase adoption, and also recommends institutional and infrastructural support to encourage market orientation and investments in biofortified crops. Our study provided evidences that scaling up sustainable market growth for biofortified foods required the convergence of consumer knowledge, awareness and expert recommendations, as well as effective communication strategies. Our concluded that dynamics of demand and supply of food must be targeted at enhancing access, availability and utilization of food to achieve goal of the SDGs.

In Kenya, smartphones are readily available at lower cost than before, allowing farmers to access agricultural information through mobile applications. However, despite increased ownership of smartphones and the availability of mobile applications, the overall usage of mobile applications is still low. This research aimed to assess the factors that determine the adoption of mobile phone applications among smallholder dairy farmers in Tharaka Nithi County of Kenya. A multistage stratified sampling procedure was used to interview 427 farmers. A Double Hurdle approach was employed to analyze the drivers of decision and extent of adoption of mobile applications. The study revealed that 51% of the respondents used mobile applications to access agricultural information. The decision to use a mobile phone application was influenced by the sex of the household head, age and level of education, distance to the market center, farming (as the primary occupation), access to credit, channels of access to information, farmer’s perception on the cost and ease of use of the mobile application. Subsequently, farm size and the various channels through which farmers access information about the applications positively influenced the number of mobile applications used. This study recommends strengthening the existing extension pathways to disseminate more information regarding the use of mobile applications among smallholder farmers. Supporting public-private partnerships will be crucial in increasing the utilization of mobile phone applications.
