[前沿资讯] 中国技术助乌兹别克斯坦棉花春播 进入全文

中国一带一路网

正值春播农忙时节,日前在乌兹别克斯坦锡尔河州,由鹏盛工业园承包种植的棉田里,中国农机忙碌作业的轰鸣声正式拉开了今年乌兹别克斯坦棉花春播序幕。乌国家水利部部长、锡尔河州州长、各州水利和农业部门官员、棉花集群公司负责人齐聚于此,一同观摩正在这片棉田上试验的中国棉花种植技术。“政府非常重视这场春播大会,各州代表都前来参观,我们非常希望中国的植棉技术能够在乌推广。”乌水利部部长哈姆拉耶夫表示,“我们必须节约每一滴水。乌兹别克斯坦人口不断增长,农业需求不断增大,但耕地面积有限,因此必须要高效利用耕地,提高种植效率。希望中国政府和企业能积极参与乌农业现代化进程”。

[前沿资讯] Beset by Swine Fever, China Turns to US for Pork Supplies 进入全文

GRO

Fallout from China’s African swine fever outbreak continues to impact the global pork market. Last week, the USDA reported a record 78,000 tonnes of pork exports to China, despite China’s 62% import duty on pork products from the US. Year-to-date US export commitments of 142,000 tonnes have already matched the annual record for pork exports to China set in 2016.

[学术文献] What drives smallholder farmers’ willingness to pay for a new farm technology? Evidence from an experimental auction in Kenya 进入全文

Food Policy

We use an incentive compatible experimental auction to measure demand for a new agricultural technology, a triple layered hermetic storage bag. When used properly, the bag creates an airtight seal that reduces storage loss from insect pests and neutralizes aflatoxin contamination in stored grain. We find that demand for this new technology is highly elastic (4.3) and that the wholesaler could increase profit by lowering the price. We also find that farmers’ valuation for the bag is not significantly different based on the medium through which information about it is communicated to them, either text, audio or video messages. This suggests that practitioners should use the cheapest option for disseminating information, which is text messaging in this context. In addition, we find that farmers who have prior awareness of the bag are willing to pay 20% more on average than those previously unaware of it. In total, the highly elastic demand for the improved bags, along with the fact that prior awareness of the bag leads to higher willingness to pay, suggests that a one-time price subsidy for the new technology could spur demand and increase future adoption.

[学术文献] Agricultural production amid conflict: Separating the effects of conflict into shocks and uncertainty 进入全文

World Development

This paper examines the effect of conflict on agricultural production of small farmers. First, an inter-temporal model of agricultural production is developed in which the impact of conflict is transmitted through violent shocks and uncertainty brought about by conflict. We test the model using a unique household survey applied to 4800 households in four micro-regions of Colombia. Our findings suggest households learn to live amid conflict, albeit at a lower income trajectory. When presence of non-state armed actors prolongs, farmers shift to activities with short-term yields and lower profitability from activities that require high investments. If violence intensifies in regions with presence of non-state armed actors, farmers concentrate on subsistence activities.

[前沿资讯] 中缅油气管道改善当地电力供应状况 为缅甸贡献直接经济收益超2亿美元 进入全文

中国一带一路网

在5艘牵引船的牵引下,中远“远富湖号”油轮缓缓停泊在位于缅甸若开邦皎漂市的马德岛港。3条输油管分别降下,与油轮输油管口对接,向港口卸油,将其储存到单座储量为10万吨的储油罐内。这些原油经过检测、加压后,将经由771公里的中缅原油管道,从中缅边境的南坎计量站进入中国。在并行的天然气管道内,从缅甸西南海域开采的天然气同样从该计量站进入中国。
