PurposeThe choice of crops to produce at a location depends to a large degree on the climate. As the climate changes and food demand evolves, farmers may need to produce a different mix of crops. This study assesses how much cropland may be subject to such upheavals at the global scale, and then focuses on China as a case study to examine how spatial heterogeneity informs different contexts for adaptation within a country.Design/methodology/approachA global agricultural economic model is linked to a cropland allocation algorithm to generate maps of cropland distribution under historical and future conditions. The mix of crops at each location is examined to determine whether it is likely to experience a major shift.FindingsTwo-thirds of rainfed cropland and half of irrigated cropland are likely to experience substantial upheaval of some kind.Originality/valueThis analysis helps establish a global context for the local changes that producers might face under future climate and socioeconomic changes. The scale of the challenge means that the agricultural sector needs to prepare for these widespread and diverse upheavals.
目的 选择在某地生产何种作物在很大程度上取决于气候。随着气候的变化和粮食需求的发展,农民可能需要生产不同的作物组合。本研究评估了在全球范围内有多少耕地可能受到这种动荡的影响,然后以中国为案例,研究空间异质性如何为国内不同的适应环境提供信息。研究结果三分之二的雨水灌溉耕地和一半的灌溉耕地可能会经历某种形式的重大变化。挑战的规模意味着农业部门需要为这些广泛而多样的动荡做好准备。

PurposeStudies on developed economies showed that imposing taxes on animal-based foods could effectively reduce agricultural greenhouse gas emissions (AGHGEs), while this taxation may not be appropriate in developing countries due to the complex nutritional status across income classes. Hence, this study aims to explore optimal tax rate levels considering both emission reduction and nutrient intake, and examine the heterogenous effects of taxation across various income classes in urban and rural China.Design/methodology/approachThe authors estimated the Quadratic Almost Ideal Demand System model to calculate the price elasticities for eight food groups, and performed three simulations to explore the relative optimal tax regions via the relationships between effective animal protein intake loss and AGHGE reduction by taxes.FindingsThe results showed that the optimal tax rate bands can be found, depending on the reference levels of animal protein intake. Designing taxes on beef, mutton and pork could be a preliminary option for reducing AGHGEs in China, but subsidy policy should be designed for low-income populations at the same time. Generally, urban residents have more potential to reduce AGHGEs than rural residents, and higher income classes reduce more AGHGEs than lower income classes.Originality/valueThis study fills the gap in the literature by developing the methods to design taxes on animal-based foods from the perspectives of both nutrient intake and emission reduction. This methodology can also be applied to analyze food taxes and GHGE issues in other developing countries.
目的对发达经济体的研究表明,对动物性食品征税可有效减少农业温室气体排放(AGHGEs),而在发展中国家,由于不同收入阶层的营养状况复杂,这种征税方式可能并不合适。因此,本研究旨在探讨同时考虑减排和营养摄入的最佳税率水平,并研究在中国城市和农村不同收入阶层征税的异质性效应。作者估计了二次几乎理想需求系统模型,计算了八类食品的价格弹性,并进行了三次模拟,通过有效动物蛋白摄入量损失和征税减少农业温室气体排放量之间的关系,探讨了相对最佳的征税区域。结果结果表明,根据动物蛋白摄入量的参考水平,可以找到最佳税率带。对牛肉、羊肉和猪肉征税可作为降低中国 AGHGEs 的初步选择,但同时应针对低收入人群制定补贴政策。一般来说,城市居民比农村居民更有潜力减少 AGHGEs,高收入阶层比低收入阶层减少更多 AGHGEs。该方法也可用于分析其他发展中国家的食品税和温室气体排放问题。

PurposeThe purpose of this paper is to test the overshooting effects of monetary expansion on prices of agricultural products at farm production, processing and circulation stages in China, and to investigate the heterogeneity of the overshooting mechanisms in these three links.Design/methodology/approachEmpirical results are obtained through the vector error correction model and the overshooting framework proposed by Saghaian et al. (2002b). Specifically, we first apply the Dickey–Fuller generalized least squares (DF-GLS) method to test the stationarity of the key variables, and then use the Johansen’s (1991) method to conduct the cointegration test. Finally, the vector error correction model is employed to examine the overshooting hypotheses in the three stages of China’s agricultural sector.FindingsEmpirical results indicate that overshooting of prices relative to monetary expansion in China’s agricultural sector is a common phenomenon, but with significant heterogeneity. Firstly, at the stage of agricultural production, the overshooting degree and restoration rate of material price are greater than those of agricultural products price. Secondly, at the processing stage of agricultural products, both the purchase price of agricultural products and industrial producer price have an overshooting effect, but the overshooting effect of the former is more significant than the latter. Thirdly, at the circulation stage of agricultural products, the overshooting coefficient of the wholesale price index of agricultural products is the most significant, while that of the retail and purchase price of agricultural products is not significant.Originality/valueThe paper contributes to proposing a comprehensive framework on testing the overshooting effects for three main stages of agricultural sector in China and empirically investigating the heterogeneity of the overshooting mechanisms in different stages with time series methods.
本文旨在检验货币扩张对我国农产品在农业生产、加工和流通环节价格的超调效应,并研究这三个环节超调机制的异质性。本文通过Saghaian等(2002b)提出的向量误差修正模型和超调框架得到实证结果。具体来说,我们首先采用 Dickey-Fuller 广义最小二乘法(DF-GLS)检验关键变量的平稳性,然后采用 Johansen(1991)方法进行协整检验。结果实证结果表明,中国农业部门相对于货币扩张的价格超调是一种普遍现象,但具有显著的异质性。首先,在农业生产阶段,物质价格的超调程度和恢复速度均大于农产品价格的超调程度和恢复速度。其次,在农产品加工阶段,农产品收购价格和工业生产者价格都存在超调效应,但前者的超调效应比后者更为显著。原创性/价值 本文提出了检验中国农业部门三个主要阶段超调效应的综合框架,并运用时间序列方法实证研究了不同阶段超调机制的异质性。

PurposeThis paper examines the impact of the COVID-19 pandemic on low-carbon consumption of dairy products through informational interventions. The empirical findings seek to enlighten developing countries' efforts in coping with climate change and potential dietary transitions.Design/methodology/approachA randomized controlled trial was designed to examine the effects of purpose-differentiated information interventions on individual dairy consumption. The experiment recruited and randomly assigned 1,002 college students into four groups to receive (or not) environmental or/and health information interventions.FindingsThe empirical analysis finds that health and combined information interventions have a positive impact on dairy consumption, while environmental information interventions' effect on dairy consumption is insignificant. In the context of the pandemic, health information interventions positively affected participants' perceptions and preferences for dairy products by delivering knowledge about their role in boosting immunity. However, environmental information interventions failed to do the same things as their insignificant effects on both perception and preference.Originality/valueMacro-external shocks, such as public health events, may offset the impact of universal information interventions promoting pro-environmental behaviors. For a smooth dietary transition to achieve long-term environmental sustainability, diverse stakeholders must be included in more individualized interventions to guide daily consumption, especially in developing countries with large populations.
本文探讨了 COVID-19 大流行通过信息干预对乳制品低碳消费的影响。设计/方法/途径设计了一项随机对照试验,以研究有目的的信息干预对个人乳制品消费的影响。实证分析发现,健康和综合信息干预对乳制品消费有积极影响,而环境信息干预对乳制品消费的影响不明显。在大流行病的背景下,健康信息干预通过提供有关乳制品在提高免疫力方面作用的知识,对参与者对乳制品的看法和偏好产生了积极影响。原创性/价值公共卫生事件等宏观外部冲击可能会抵消促进亲环境行为的普遍信息干预的影响。为了实现膳食的平稳过渡,实现环境的长期可持续性,必须让不同的利益相关者参与到更加个性化的干预措施中,以指导日常消费,尤其是在人口众多的发展中国家。

PurposeThis paper explores the relationship between state-led urbanization and primary industry development using the difference-in-differences (DiD) method.Design/methodology/approachThe study uses the DiD method.FindingsExploiting county-city mergers during 2010–2018, the key strategy to expand the city outward and promote urbanization on the urban fringe by local government, the authors find that county-city mergers led to the growth of primary industry decline by 4.23%. The result can be explained by the loss of essential production factors, including land and labor used for farming. In addition, the negative effect is more pronounced for counties with more substantial manufacturing. The results indicate that urbanization in China relocates land and labor; however, it does not improve the efficiency of agricultural output.Originality/valueThis paper contributes to the understanding of urbanization and rural development from the perspective of the primary industry by showing production factor redistribution. Second, this study complements the literature on local government mergers.
研究结果作者利用 2010-2018 年期间的县市合并--地方政府向外扩张城市和促进城市边缘地区城市化的重要战略--发现,县市合并导致第一产业增长率下降了 4.23%。造成这一结果的原因是基本生产要素的流失,包括用于农业生产的土地和劳动力。此外,对于制造业较发达的县来说,负效应更为明显。研究结果表明,中国的城镇化转移了土地和劳动力,但并没有提高农业产出效率。其次,本研究补充了有关地方政府兼并的文献。

PurposeLarge-scale farm management in China has developed rapidly in recent years. Large-scale farmers face substantial operating risks, requiring extensive price risk management. However, the agricultural insurance and futures markets in China are incomplete. This study aims to analyze the price-risk-management behaviors of large-scale farmers under incomplete market conditions, with a focus on the interconnections between large scale farmers' subjective preferences (risk preferences, time preferences), liquidity constraints and their price risk management.Design/methodology/approachThe authors construct an analysis framework to reveal the impact of large-scale farmers' risk preferences, time preferences and liquidity conditions on their price-risk-management behaviors under incomplete market conditions. Using data from field surveys and subjective preference experiments involving 409 large-scale grain farmers in China, an empirical analysis was conducted using the bivariate probit model.FindingsThe results show that risk-averse farmers will use risk transfer (such as contract farming) and risk diversification (such as multi-period sales) to avoid price risk. However, farmers subject to liquidity constraints and strong time preferences will not choose risk diversification, and the interaction between time preferences and liquidity constraints will strengthen this decision. The larger the farm-management scale, the greater the impact.Originality/valueThe authors focus on rapidly developed large-scale farm management in China. Appropriate price risk management is required by large-scale farmers due to their substantial operating risks. Considering the incomplete conditions of agricultural insurance and futures markets, the results of this study will help identify behavioral characteristics of large-scale farmers and optimize their price-risk-management strategies, further stabilizing large-scale farm management.
目的 近年来,中国的大规模农场管理发展迅速。规模经营农户面临着巨大的经营风险,需要进行广泛的价格风险管理。然而,中国的农业保险市场和期货市场并不完善。本研究旨在分析不完全市场条件下规模化农户的价格风险管理行为,重点研究规模化农户的主观偏好(风险偏好、时间偏好)、流动性约束与其价格风险管理之间的相互关系。研究结果表明,风险规避型农户会利用风险转移(如订单农业)和风险分散(如多期销售)来规避价格风险。然而,受流动性约束和强烈时间偏好影响的农民不会选择风险分散,而时间偏好和流动性约束之间的相互作用会加强这种决策。农场管理规模越大,影响就越大。由于规模化经营风险巨大,规模化农户需要适当的价格风险管理。考虑到农业保险和期货市场的不完备性,本研究的结果将有助于识别规模化农户的行为特征,优化其价格风险管理战略,进一步稳定规模化农场管理。

PurposeThis research examined the impacts of diversified income from trading caterpillar fungus on pastoral households' livestock production and income. The specific objectives were to identify the main factors underlying participation in caterpillar fungus trade and to explore the impacts of a diversified income from trading fungus on livestock production activities and income.Design/methodology/approachData were collected from a pastoral household survey (n = 503) in five Tibetan Autonomous Prefectures. The authors employed propensity score matching (PSM) procedures to estimate the effects of participation in trading caterpillar fungus.FindingsPastoral households participating in caterpillar fungus activities maintain smaller herds, sell fewer animals for profit, slaughter more livestock for family consumption and experience fewer livestock deaths compared to nonparticipants. There is also some evidence that pastoral households participating in caterpillar fungus activities have a higher annual income compared to nonparticipants.Research limitations/implicationsA direct measure of grassland degradation was not included due to the data limitation. The estimated average treatment effects could differ under different observed households' characteristics.Originality/valueThis study fills a gap in the literature on the impacts of diversified income on livestock production activities. The authors provide a new perspective on the controversy over the extraction of caterpillar fungus. This study contributes to exploring the dual role of income diversification in addressing poverty and grassland resource degradation for Tibetan pastoral communities.
目的研究冬虫夏草交易多元化收入对农户畜牧业生产和收入的影响。具体目标是确定参与冬虫夏草贸易的主要因素,并探讨冬虫夏草贸易带来的多样化收入对畜牧生产活动和收入的影响。设计/方法/方法数据来自5个藏族自治州的牧民家庭调查(n = 503)。作者采用倾向得分匹配(PSM)程序来估计参与交易冬虫夏草的影响。研究发现,与不参与冬虫夏草活动的家庭相比,参与冬虫夏草活动的家庭维持较小的畜群,出售更少的牲畜以获取利润,屠宰更多的牲畜供家庭消费,牲畜死亡人数更少。也有一些证据表明,参与冬虫夏草活动的牧民家庭的年收入高于不参与冬虫夏草活动的牧民家庭。研究局限/启示由于数据有限,未包括草地退化的直接测量。在不同的观察家庭特征下,估计的平均处理效果可能会有所不同。原创性/价值本研究填补了多元收入对畜牧生产活动影响的文献空白。作者对冬虫夏草提取的争议提供了一个新的视角。本研究有助于探索收入多样化在解决藏族牧区贫困和草地资源退化问题中的双重作用。

Purpose

Smart farming technologies (SFTs) can increase yields and reduce the environmental impacts of farming by improving the efficient use of inputs. This paper is to estimate farmers' preference and willingness to pay (WTP) for a well-defined SFT, smart drip irrigation (SDI) technology.

Design/methodology/approach

This study conducted a discrete choice experiment (DCE) among 1,300 maize farmers in North China to understand their WTP for various functions of SDI using mixed logit (MIXL) models.

Findings

The results show that farmers have a strong preference for SDI in general and its specific functions of smart sensing and smart control. However, farmers do not have a preference for the function of region-level agronomic planning. Farmers' preferences for different functions of SDI are heterogeneous. Their preference was significantly associated with their education, experience of being village cadres and using computers, household income and holding of land and machines. Further analysis show that farmers' WTP for functions facilitated by hardware is close to the estimated prices, whereas their WTP for functions wholly or partially facilitated by software is substantially lower than the estimated prices.

Practical implications

Findings from the empirical study lead to policy implications for enhancing the design of SFTs by integrating software and hardware and optimizing agricultural extension strategies for SFTs with digital techniques such as videos.

Originality/value

This study provides initial insights into understanding farmers' preferences and WTP for specific functions of SFTs with a DCE.

智能农业技术(SFTs)可以通过提高投入物的有效利用来提高产量并减少农业对环境的影响。本文旨在评估农民对智能滴灌技术的偏好和支付意愿(WTP)。本研究采用混合logit (MIXL)模型对中国北方1300名玉米农户进行离散选择实验(DCE),以了解农户的WTP对SDI各功能的影响。结果表明,农民对SDI的总体偏好以及其特定的智能感知和智能控制功能具有强烈的偏好。然而,农民对区域一级农艺规划功能的偏好程度不高。农民对SDI不同功能的偏好具有异质性。他们的偏好与他们的教育程度、担任村干部和使用电脑的经历、家庭收入以及持有土地和机器有很大关系。进一步的分析表明,农民对由硬件实现的功能的WTP接近于估计价格,而他们对全部或部分由软件实现的功能的WTP大大低于估计价格。实践启示实证研究的结果为通过软件和硬件的整合来加强农村农村服务区的设计以及利用视频等数字技术优化农村农村服务区的农业推广策略提供了政策启示。原创性/价值本研究提供了初步的见解,以了解农民的偏好和WTP的特定功能的SFTs与DCE。
