Commercial cash crop production and households’ economic welfare: Evidence from the pulse farmers in rural China 下载免费PDF全文
Whether promoting cash crop production can increase household welfare has long been the focus of the food policy debate. This study first investigated the determinants of household behavior in commercial pulse farming. It then examined how households’ commercial pulse production improves their economic welfare. We used a dataset of 848 households collected from 2018 to 2019 to estimate the determinants of household behavior in commercial pulse farming by the Heckman two-step model. The endogenous treatment regression (ETR) method was employed to examine the impact of commercial pulse farming on household economic welfare. The results showed that factors such as market purchase prices, agricultural technology services, farmers’ access to loans, and government subsidies promoted smallholders’ commercial pulse farming; production costs and perceptions of climate change risks constrained smallholders’ commercial pulse production. Overall, commercial pulse production has increased household farm income but there was a limited impact on household off-farm income. Our findings suggest that policies aiming to increase households’ cash crop production and market access could significantly improve the economic welfare of pulse farmers. 相似文献

“三农”视角下陕西种植业保险市场分析 总被引:1,自引:0,他引:1
介绍了陕西种植业保险市场的发展现状,表明陕西种植业保险的开展情况并不理想。分析了陕西农村种植业保险发展中面临的突出问题,一是种植业风险种类多,发生频率高,损失大;二是商业保险公司种植业保险的有效供给严重不足;三是农户的有效需求受到制约;四是政府对种植业保险缺乏制度化支持。基于"三农"视角,提出了陕西种植业保险发展的策略选择:鼓励商业保险公司积极介入种植业保险市场,建立完备的农业再保险体系;加强种植业保险的宣传力度,加快农业产业化的进程;加大对种植业保险的政策支持力度,推动种植业保险发展。 相似文献

牧猪是两汉养猪业中较为常见的现象。牧猪地点一般选择在苑囿、山谷、水泽中,牧猪者以农奴、佣工、书生为主。两汉的"牧猪"现象与养猪业的空前发展有关,也取决于汉代较高的猪肉价格;经学书生牧猪,主要将其作为一种"勤工俭学"方式,半工半读。牧猪现象的普遍,一定程度上反映了汉代养猪业的盛况。 相似文献

通过田间小区试验,研究了施用羊粪、牛粪、鸡粪等不同肥源的腐熟农家肥和商品有机肥对烤烟生长发育、产量和产值量的影响。结果表明:鸡粪+油枯+天然钾矿粉(JYK)处理对土壤改良效果、烟株田间长势、病虫害发生情况、烟叶产量、产值等指标优于商品有机肥(S)、羊粪+油枯+天然钾矿粉(YYK)、鸡粪+天然钾矿粉(JK)3个处理,但无显著差异(P>0.05);在有机种植条件下,牛粪+油枯+天然钾矿粉(NYK)处理对土壤改良效果、烟株田间长势、病虫害发生情况、产量、产值等一系列指标显著低于(P<0.05)或底于S,YYK,JK,JYK处理。因此,JYK处理为有机种植最佳的培肥方式,NYK的培肥方式可能不适用于有机种植。 相似文献

Flexible exchange of farming device data 总被引:2,自引:0,他引:2
A new trend in the farming business is to replace conventional farming devices with computerized farming devices. Accordingly, numerous computer-based farming devices for logging, processing and exchanging data have recently been installed on moving farm machinery such as tractors. The exchange of data generally takes place between the devices and farming systems, mostly installed at the premises of farmers, contractors, advisory services, etc. In most cases, data exchange is based on farming data exchange standards and is bi-directional. Bi-directional data exchange allows different devices and systems to exchange data based on a predefined set of rules. In consequence, many hand-coded data exchange solutions have been developed in the farming business. Although efforts regarding incorporating data exchange standards have been made, their actual usage so far has been limited, due to the fact that hand-coded bi-directional data exchange solutions have proven themselves too complex to maintain. Maintenance need to occur as requirements change frequently and the existing data exchange techniques lack flexibility with regards to efficient requirements change management. In addition, requirements change results in managing low-level code rather than a high-level specifications. This paper presents a bi-directional data exchange solution in the farming business that is based on high-level specifications without any need for hand-coding. The proposed solution supports ISOBUS based bi-directional data exchange as well as efficient requirements change management through a graphical user interface. The paper also demonstrates the use of the proposed solution based on a farming case study and open source technologies. 相似文献
