农业绿色发展路径及其“十四五”取向

随着农业资源环境问题的凸显,绿色发展成为农业发展的主流。基于对农业绿色发展关键要素的界定,提出农业绿色发展的三个阶段:去污,即农业生产过程的清洁化;提质,实现产地绿色化和产品优质化;增效,绿色成为农业高质量发展的内生动力。近年来,农业绿色发展取得了一定成就,但也存在政策分散、数据基础不牢、农业补贴制度改革进展缓慢、行政执法“一刀切”等问题。“十四五”时期,应以绿色发展驱动农业高质量发展,通过抓落实提高政策实效;注重摸清家底,摒弃部分无数据支撑的量化目标;加强对执法和行政的督察巡查,对政策执行过失加大问责力度;不断深化农业支持保护制度,向绿色生态方向改革。     

南方丘陵区新增耕地质量空间特征研究*——以江西省宜春市为例

［目的］粮食安全的根本是在耕地，关键在于耕地质量。目前新增耕地主要源于土地开发项目、城乡建设用地增减挂钩土地复垦项目等，这些新增耕地需要对其开展耕地质量等别评定工作，了解新增耕地的质量状况，分析其空间特征，这对落实国家耕地保护制度、开展农村土地整治工作等具有重要作用。［方法］文章以南方典型丘陵区域——江西省宜春市作为研究区域，在新增耕地质量评价的基础上，运用地统计学、景观生态学、Arcgis空间分析技术和典型相关分析方法，研究宜春市新增耕地质量的空间特征，掌握耕地质量等别的分布规律，了解耕地质量的影响因素，为制定合理的耕地资源利用与保护政策提供依据。［结果］（1）Moran′s I值结果表明宜春市2014年新增耕地利用质量在空间分布上的空间自相关性最强，而耕地自然质量空间自相关性最弱。（2）景观破碎度指数结果表明优、高等别的新增耕地质量破碎度大于中、低等别的； 多样性指数结果表明新增耕地质量多样性指数比较大； 优势度指数结果表明新增耕地质量等别优势度指数比较小，与多样性指数结果相呼应； 均匀度指数结果表明，新增耕地质量等别均匀度指数相差不大，新增耕地质量等别比较均匀。（3）质心结果表明2013—2014年间宜春市新增耕地质量的格局整体上是向西南方向变化。［结论］宜春市新增耕地质量不高； 新增耕地的利用水平差异性较小，自然本底状况差异较大； 新增耕地质量等别类型多，各质量等别类型耕地均有增加，耕地质量参差不齐，较高等地的新增耕地相对低等地而言更破碎化； 新增耕地的开发格局向着西南方向移动； 该研究为南方丘陵区的新增耕地保护提供了一定的参考依据。     

中国农业农村发展七十年:成就、经验与展望——中国农业经济学会第十次会员代表大会暨2019年学术研讨会综述

2019 is the 70 th anniversary of the founding of the people’s Republic of China and the key year for implementing the rural vitalization strategy.Summarizing the great achievements made by agriculture and rural areas in the past 70 years will have an important theoretical value for promoting the modernization of agriculture and rural areas and the strategy of rural revitalization.Under such circumstances,the 10 th member congress and 2019 academic seminar of CAAE was successfully held in Beijing.The key to promote rural revitalization lies in deepening rural reform,focus on the property right system and market-oriented allocation of factors,and establish a system and mechanism of free circulation and equal exchange between urban and rural areas.In order to promote the organic connection between small-scale peasant and the modern agriculture,it is necessary to speed up the development of agriculture social service industry.Finally,it is suggested to adhere to the two-wheel drive of rural revitalizationand new urbanization,promote the effective coverage of rural public services,and improve the rural governance mode of combining autonomy,rules of law and virtue.     

Preventing motor vehicle crash injuries and deaths: science vs. folklore lessons from history

Abstract

Not long after the beginnings of motorization in the early 1900s, deaths and injuries from motor vehicle crashes became a problem in a number of high-income-countries (HIC)s, especially the United States. With the biggest problem the US led early efforts to address this issue, and for six decades these efforts were based on folklore (ie a body of widely held but false or unsubstantiated beliefs). They were not evaluated, but clearly were unsuccessful as crash deaths and injuries continued to rise. It was not until the 1970s that a broader range of countermeasures began to be adopted and was scientifically evaluated, and as a result, crash deaths and injuries declined. This history has important lessons today for many low-and-middle-income countries that have growing numbers of motor vehicle crash deaths and injuries, many of which are pedestrians and motorcyclists. This is because there continue to be advocates for many of the failed approaches (especially educational) that dominated the early efforts in HICs.

黔东南山地生态农业发展评价及预测研究

[目的]对2012~2016年黔东南州山地生态农业发展做出评价,并预测其2018~2027年的发展情况,以期了解黔东南地区农业可持续发展能力及未来趋势的变化规律。[方法]以黔东南及贵州《2013~2017年统计年鉴》为数据来源,通过构建评价指标体系,利用层次分析法及加权评分法对2012~2016年山地生态农业发展做出评价;并运用灰色模型,借助Matlab工具,对黔东南山地生态农业发展做出预测。[结果]2010~2016年黔东南州山地生态农业的经济、生态、社会效益处于发展上升阶段,协调度良好,但生态效益发展最低,其中2015年经济、社会、生态系统可持续发展良好,但由于持续保护,2016年出现生态保护过度,经济和综合效益下降现象,因此发展模式有待于向发展经济和社会效益方面倾斜;黔东南州山地生态农业在2018~2027年将会处于发展上升阶段,但其发展缓慢,仍存在一定限制因素。[结论]政府应积极调整农业产业结构,转变农业发展思路,可将部分生态农业与旅游相结合,发挥区位特色的同时,提升品牌的知名度。加大力度引导农业园区和重点产业的发展,推进农业农村改革试点的运行,加大新型农人的培育,促进高效、现代、特色生态农业的发展。     

Determinants of energy use in the informal food sector

Although enterprises in the informal food sector require energy to transform, cook and process food, energy-use patterns in this sector are not well understood by policymakers and the local-level authorities who regulate their trading activities. This paper reviews relevant literature and presents empirical data collected in Rwanda, Senegal and South Africa on the use of traditional and modern energy sources by informal food sector operators. Our sample includes male- and female-operated enterprises in the urban centres of three African countries where the informal food sector is important, not only for providing the convenience of affordable and readily prepared meals, but also as a source of income for women and men in developing countries. Multiple fuel-use and energy-stacking strategies are common among informal food enterprises and policy needs to acknowledge this if it is to intervene in ways that will benefit both enterprises and regulators.     

One village,one product: Agro‐industrial village corporatism in contemporary China

This paper investigates the implementation of “one village, one product” (OVOP) in four peri‐urban villages in China's Yangtze River Delta. China's agricultural transformation, including the introduction of new corporate actors and the growing pressure of market discipline, has challenged the relevance of villages in the organization of agricultural production. In response, village cadres in thousands of Chinese villages have used OVOP to transform their villages into agro‐industrial firms and re‐exert their control over the agricultural surplus, echoing earlier examples of village corporatism. Rooted in agricultural specialization, OVOP encompasses a diversity of strategies for the production of locality‐based value. I disaggregate these strategies into four sociospatial dimensions that comprise locality—place, network, territory, and scale. Place‐based branding is the dominant strategy, but village cadres also pursue complementary sociospatial strategies to ensure their control over the realization of the brand's value and reconstitute their redistributive and administrative powers.     

Women farmers’ participation in the agricultural research process: implications for agricultural sustainability in Ethiopia

Empowering women farmers to participate in agricultural research is a key strategy for sustainable agricultural development. Women empowerment has the potential to improve their roles in agricultural production while enhancing nutrition and food security. Although new agricultural development policies are focusing on improving women engagement in agriculture, there is limited literature on women empowerment in relation to agricultural research. This study used mixed methods to analyse women farmers’ participation in four stages of the agricultural research process – design, testing, dissemination, monitoring and evaluation. Two hundred and thirty individual interviews with women farmers and 16 focus group discussions with men and women farmers were conducted in four Woredas (districts) of Ethiopia. Quantitative data were analysed using binary and multivariate probit models. Qualitative data were analysed using line-by-line coding. The results showed that several empowerment indicator variables significantly (p?≤?.001) influenced women’s participation in different stages of agricultural research. Specifically, input in production decisions, autonomy in plot management, membership to farmer groups, and ability to speak in public enhanced women’s participation in different stages, in addition to access to information and extension services, education and land size. Cultural norms hindered women’s empowerment and engagement in research. To foster sustainable agriculture development, it’s important to integrate holistic and proactive gender perspectives into research strategies to increase women’s participation in farmer research groups, access information and knowledge, have voice and challenge constraining cultural norms and traditions.
