借助基于主体建模方法(agent-based-modeling,ABM)建立农户决策的演化博弈模型,以社会网络为技术扩散载体并假设社会网络中的农户全部采纳传统技术,设计4组控制变量实验仿真研究个体学习、社会效应和两者耦合作用对农业创新技术扩散的影... 借助基于主体建模方法(agent-based-modeling,ABM)建立农户决策的演化博弈模型,以社会网络为技术扩散载体并假设社会网络中的农户全部采纳传统技术,设计4组控制变量实验仿真研究个体学习、社会效应和两者耦合作用对农业创新技术扩散的影响,并进一步通过改变参数探究农户平均交流人数、创新技术理论收益和两者耦合作用的影响。研究发现,仅存在个体学习时农业创新技术扩散效率大幅度增长,仅存在社会效应时扩散效率有所下降,同时存在个体学习和社会效应产生的耦合作用并非二者净作用的简单相加,而是产生了部分促进作用;农户平均交流人数的增长产生了阻碍作用,且创新技术理论收益的增长可以消除不同农户平均交流人数的差异;创新技术理论收益的增长产生了促进作用,促进效果呈非线性特征,且具有产生影响的起飞点。最后根据研究结论提出相应的政策建议。 展开更多

This paper traces the origins and achievements of the R^seau Ouest et Centre Africain du Riz--ROCARIZ (West and Central Africa Rice Research and Development Network). The ROCARIZ institutional arrangement showed that rice science is approached from multi-stakeholder perspectives that place end users and entrepreneurs at the center of research for development, and collaboration among rice-based stakeholders can be enhanced and sustained. The ROCARIZ used competitive research grants through multi-stakeholder task forces to generate, adapt, and facilitate the adoption of rice-based technologies and approaches by resource poor households. The grants contributed to: (1) farmer adoption of high yielding and multiple stress resilient lowland NERICAs (New Rices for Africa) (NERICA-L); (2) producer access to credit and services resulting in increased marketing of quality seed rice, paddy, and grain rice by farmer entrepreneurs and poor rural households; (3) improved skills of stakeholders on the use of impact assessment tools to demonstrate adoption of rice-based technologies; (4) enhanced skills of rice breeders in molecular assisted marker selection to shorten the varietal development process; and (S) experiential learning and sharing to improve access to information and knowledge. 展开更多

In recent years, many countries implement the TBT in the export trade practice of agricultural products, which has greatly positive influence on the Chinese agricultural products export enterprise. On the basis of green technical innovation concept, the paper had determined the enterprise green technical innovation motivation mechanism, analyzed the influence of TBT on green technical innovation of the enterprise, and integrated Chinese reality to analyze the influence of TBT on green technical innovation of Chinese agricultural enterprise. Finally, based on the above analysis, the paper proposed corresponding suggestions to the Chinese government. 展开更多

This study estimates the environmental and socioeconomic impacts of coffee production in the agroforestry system in the settlements of farmers located in the West of the state of Silo Paulo, Brazil, in the region known as Pontal of Paranapanema, aiming at the development of programs to support the growth of production sustainable coffee and programs to protect the coffee activity before the possible global climate change. The settlements are located in areas with sandy soils and highly degraded by human action Moreover, the region is considered marginal for the production of coffee, because it is subject to periods of high temperatures, prolonged drought and frost risk, which hinders the sustainability of farms. The environmental and socioeconomic impacts of agroforestry are analyzed through Ambitec-agro system, consisting of a set of indicators aimed at ex-post evaluation of the contribution of technological innovation to environmental, social and economic development of an agricultural activity. The system Ambitec involves: (1) general data collection about the technology; (2) application of questionnaires with adopters selected and insertion of data on impact indicators spreadsheets via platform MS-Excel and to obtain quantitative results and impacts partial indexes and aggregates the impact of technology selected; (3) analysis and interpretation of indices obtained, which vary between -15 and 15. The results indicate that agroforestry management can contribute to: (1) maintaining or increasing the sustainability of traditional coffee-growing regions in the case of sudden climate change; (2) the expansion of the coffee regions now considered unsuitable for the cultivation of coffee; (3) for sustainable regional development. 展开更多
