在新的粮食安全危机面前我国的应对策略 总被引:3,自引:0,他引:3
赖昭瑞 《山东省农业管理干部学院学报》2008,23(5):51-54
时隔30年之久,世界性的粮食危机又出现在人们的面前。当前国际粮价高涨,波动到世界很多地方,甚至引起了一些非洲国家、加勒比海沿岸国家的民众骚乱,造成部分国家政局动荡,粮食危机直接导致了海地总理亚历克西今年4月12日的下台。中国农产品供给告别短缺时代、中央对"三农"问题的重视和相关政策的调整赋予了研究粮食安全问题崭新的背景,但是中国粮食供应偏紧的局面、中国进口的粮食数量将会增加以及单纯依靠提高粮食单产来解决中国粮食供应缺口的空间已经很小却是不争的事实。不仅如此,未来各种自然、经济、社会、人文以及制度因素仍会对中国的粮食安全问题产生极大的影响。可见,在新的粮食危机面前研究我国的应对策略意义重大。本文在指出我国粮食安全方面存在的主要问题基础上,考虑了建立我国粮食安全体制应掌握的基本原则,最后提出了确保国家粮食安全的政策选择,其中包括巩固农业基础地位、推进农业产业化、保护耕地资源、增加农业投入、发展农业科技、完善粮食流通体制、节约粮食和储备粮食七个方面的内容。 相似文献

Food insecurity, and its extreme form, hunger, occur whenever the accessibility to an adequate supply of nutritional and safe foods becomes restricted or unpredictable. They are recurring problems in certain regions of the US, as well as in many parts of the world. According to nation-wide surveys conducted by the US Bureau of the Census, between 1996 and 1998 an estimated 9.7% of US households were classified as food insecure (6.2% being food insecure without evidence of hunger, and 3.5% being food insecure with moderate to severe hunger). This means that approximately 10 million households each year did not always have access to enough food to meet basic needs. A potential tool in the fight against food insecurity and hunger is information technology (IT), since its use and range of application continue to grow at astonishing rates. The study presented here examined the question of how information technology, particularly the Internet, can be used to promote food security. The study used an action science research approach, and a case study strategy, with the food security system of Oktibbeha County, Mississippi selected as the case for study. The research design was a two-phase process. Phase one consisted of a needs assessment among food assistance organizations in Oktibbeha County, and included interviews of key food assistance personnel. Phase one also included a survey of IT subject matter experts to seek their opinions about the current state of Web-based information technology. Phase two involved an analysis of various IT implementation issues, as well as the development of a Web-based food security information system prototype tool. The needs assessment results indicated that (a) certain food security system and information needs existed among the food assistance organizations in Oktibbeha County, and (b) appropriate information technologies existed that could be applied to these needs. The food security needs related to better communication and coordination of information, such as program information, food site inventory information, client history information, food donation information, and nutrition education information. In regard to technology development, a variety of scenarios were examined. These included client-side approaches, server-side approaches, simple e-mail-based systems, Java-based systems, systems based on the Common Gateway Interface (CGI), and commercial database systems. In applying the needs assessment and survey results, the researcher developed a prototype Web site (including a series of online database tools) that could be used to promote food security in counties such as Oktibbeha County. The results of this research show that appropriate, Internet-based, IT holds promise for the reduction of certain social problems, such as food insecurity and hunger. 相似文献

Food issues are generally regarded as agricultural and rural issues. The urban food system is less visible than such other systems as transportation, housing, employment, or even the environment. The reasons for its low visibility include the historic process by which issues and policies came to be defined as urban; the spread of processing, refrigeration, and transportation technology together with cheap, abundant energy that rendered invisible the loss of farmland around older cities; and the continuing institutional separation of urban and rural policy. Despite its low visibility, the urban food system nonetheless contributes significantly to community health and welfare; to metropolitan economies; connects to other urban systems such as housing, transportation, land use, and economic development; and impacts the urban environment. We examine existing or potential city institutions that could offer a more comprehensive look at the urban food system. These include the city department of food, the food policy council, and the city-planning department. 相似文献
