ABSTRACT

This article examines world rice price transmission and volatility spillovers across six major Asian rice markets over the period 2005-13. In addition to the conventional GARCH models, we use a panel GARCH framework to estimate the spillover effects along with the consideration of heterogeneity and interdependence among countries. Empirical results suggest that changes in the world rice price affected not only the price levels of domestic rice markets but also their conditional variances. Moreover, interdependence across rice markets contributed to a strong spillover of a price shock in one country to another within the region.  相似文献

The number of older people is growing globally and therefore there is an implication for providing products and services to facilitate access to nutritious food, considered fundamental for maintaining health and independence. Historically, older consumers have been unattractive to marketers, however improved finances and lifestyles indicate the “grey pound” has the potential to become lucrative. This exploratory research seeks to identify the current expectation of Scottish older consumers in relation to the products and services available in the supermarket and food retailers. A questionnaire was distributed to participants aged over 50 years in Scotland to voice the opinion of the older consumer in relation to shopping experience and availability of product. The results support previous research indicating the improved lifestyles of older consumers, demonstrating that previous perceptions of older people as impoverished and immobile are not representative of this group. This study contributes to the demand for more information on older consumers׳ food shopping habits and preference in Scotland. It attempts to provide useful recommendations for supermarkets and food retailers in fulfilling the needs of this rising consumer segment. This research concludes that supermarkets could improve access to both products and services to meet the demand from this growing segment of society, through better understanding of their requirements in terms of customer service, shopping experience, product size, price, access and mobility.  相似文献

2008年9月中国乳业几乎一夜之间集体沦陷于三聚氰胺掺假事件。中国食品安全的四大制度体系随即面临反思和重构。由此我们不禁反思在这个关系食品安全的全链条环节上,为什么经常出问题。本文借由当下在中国发生的一系列食品安全问题对照与借鉴国外经验对中国的食品安全问题进行探析,介绍了我国目前食品安全的现状,并简要分析了产生食品安全问题产生的原因,并就食品安全问题以及可能解决的方案进行探讨。  相似文献

不同烹调方法对食品营养素的影响   总被引:1,自引:0,他引:1  
营养素是食品中重要养分,在烹调过程中,营养素也会发生改变。烹调通过增加色、香、味等,使食品更利于吸收,但烹调过程会破坏食品的一些营养素,而不同烹调方法对食品营养素的影响也不同。  相似文献

Shortfalls in global food production, coupled with the growing visibility of climate change's disruptive effects, have underlined for many observers the importance of devoting rural lands to their ‘optimal’ use, where they can make maximal contributions to the global imperatives of feeding the human population and maintaining vital environmental services. In this context observers have endorsed rural land use planning as a way to insure that, at least in theory, lands get devoted to their best uses. In practice, land use planning in the developing world has resembled ‘organized anarchy’. Small landholders with insecure land tenure, overseas investors seeking large land deals, NGOs representing indigenous peoples, government officials, and staff from international environmental NGOs and multilateral organizations have come together in strategic action fields to struggle over and sometimes negotiate land use plans for contested landscapes. These plans represent a strategic, spatially explicit response to the climate change–biodiversity–food security crisis.  相似文献

研究目的:系统剖析大食物观视阈下耕地利用转型的现实挑战、理论逻辑与实现路径,为探寻与大食物观相适应的耕地利用转型策略提供参考。研究方法:文献分析法、系统推论法和归纳演绎法。研究结果:当前亟需与大食物观相适应、相匹配的耕地利用转型策略;大食物观视阈下的食物需求、食物安全目标、耕地利用目标与耕地利用转型之间存在逻辑关联;面向大食物观,提出了包括由人口—资源—食物协调的布局机制、刚性管制与弹性调控复合分区机制、基于管控强度差异的耕地发展权补偿机制、基于经营主体分类引导的耕地利用效率提升机制、基于耕作行为激励的可持续集约利用机制构成的耕地利用转型路径体系。研究结论:大食物观是我国新发展阶段耕地利用转型的重要引领,推进耕地利用转型是践行大食物观的关键支撑,探索并实施多路径协同的耕地利用转型策略是促进耕地资源可持续利用并服务于国家食物安全重大战略的应时之举。  相似文献

The determinants of migration have been widely studied but research has rarely addressed the roles of food insecurity and gender in the migration decision process. To address these gaps, we examine these relationships for 135,078 individuals across 94 low- and middle-income countries. We use a series of binary-choice models with sample selection and data from the 2014–2015 waves of the Gallup World Poll Survey, which includes the first global measure of individual-level food insecurity. Results, which are robust, indicate that food insecurity is an important determinant of both migration intentions and preparations, and the probability of migration intentions increase monotonically with the severity of food insecurity, and the probability of migration preparations decrease. These relationships also differ significantly by gender and level of gross national income. Evidence suggests a need for increased coordination between the international food security and migration policy agendas.  相似文献
