西藏食物保障的自然资源相对优势分析

对西藏食物保障的自然资源相对优势研究表明 ,光能、生物、旅游资源是西藏食物保障的突出相对优势。这些资源具有独特、再生和易于持续开发利用等突出特点 ;水利资源和矿产资源具有明显的开发利用优势 ,但是 ,与经济落后形成了极大的反差 ,目前开发乏力 ,开发利用将带来后续管理与环境保护的沉重负担 ;耕地、草地与森林资源既具有明显的优势 ,又有突出的劣势 ,主要表现为数量的优势与质量的劣势。西藏未来食物保障 ,取决于如何将这些资源的相对优势有效组合、综合管理和合理开发利用。     

宁夏人口、粮食与水土资源利用

人口、粮食与水土资源利用是宁夏回族自治区国民经济发展中的重要问题。文中分析了宁夏人口、粮食与水土资源利用现状,应用灰色系统理论及回归分析,建立人口、粮食预测模型,对2000年宁夏的人口、粮食进行了预测。分析2000年水土资源不同开发利用条件下粮食供需平衡情况后指出,充分合理利用黄河水资源,扩大灌溉面积,配合先进的农业技术,宁夏粮食不仅能自给,而且还能提供一定数量的商品粮。最后提出了解决粮食问题,防止生态环境恶化的主要途径。     

上海市绿色食品的发展前景与策略

为更好地协调环境、资源、食品、健康的关系,适应人们对农产品需求的变化及社会可持续发展的需要,世界各国纷纷提出了发展无污染农产品的设想。我国亦于1990年推出了“绿色食品”活动。该文在综观国内外绿色食品研究和发展概况的基础上,分析了上海市发展绿色食品的有利条件,并提出了发展对策和建议。     

充分发挥作物品种资源在粮食增产中的作用

我国十分重视品种资源的收集保存和研究利用，并利用各种优异品种资源育成一批又一批新品种，主要粮食作物推广的品种经历了４～５次更换，随之粮食作物产量由５０年代的１１５５ｋｇ／ｈm₂增加到１９９４年的４０６５ｋｇ／ｈm₂。迄今，我国收集的粮食作物品种资源约２４万份，并对其中２０万份进行了主要农艺性状、品质、抗逆、抗病虫鉴定和评价，筛选出大量具有优良性状的资源，有的已在我国粮食增产中发挥了明显作用，应充分利用新技术，加速现有粮食作物品种资源的鉴定和开发利用；根据生产和育种的需要，不断收集新资源，深入鉴定筛选优良资源；并创造新物种或中间材料。     

Genetically Modified (GM) Crops: Precautionary Science and Conflicts of Interests

Risk governance of GM plants and GMfood products is presently subject to heatedscientific and public controversies. Scientistsand representatives of the biotechnologyindustry have dominated debates concerningsafety issues. The public is suspicious withregard to the motives of scientists, companies,and political institutions involved. Thedilemmas posed are nested, embracing valuequestions, scientific uncertainty, andcontextual issues. The obvious lack of data andinsufficient information concerning ecologicaleffects call for application of thePrecautionary Principle (PP). There are,however, divergent opinions among scientistsabout the relevance of putative hazards,definition of potential ``adverse effects,' andwhether actions should be taken to preventharm. The reliance on the concept ofsubstantial equivalence in safety evaluation ofGM food is equally controversial. Consequently,value assumptions embedded in a scientificframework may be a barrier for employment ofthe PP. One of our major conclusions is thatprecautionary GMP usage requires riskassessment criteria yet undeveloped, as well asbroader and more long-term conceptions of risk,uncertainty, and ignorance. Conflicts ofinterest and public participation are otherissues that need to be taken intoconsideration. GMP governance regimes that arejustifiable from a precautionary and ethicalpoint of view must transcend traditionalscientific boundaries to include alternativescientific perspectives as well as publicinvolvement.     

You Are What You Eat: Genetically Modified Foods, Integrity, and Society

Thus far, the moral debateconcerning genetically modified foods (GMF) hasfocused on extrinsic consequentialist questionsabout the health effects, environmental impacts,and economic benefits of such foods. Thisextrinsic approach to the morality of GMF isdependent on unsubstantiated empirical claimsand fails to account for the intrinsic moralvalue of food and food choice and theirconnection to the agent's concept of the goodlife. I develop a set of objections to GMFgrounded in the concept of integrity andmaintain that food and food choice can beintimately connected to the agent's personalintegrity. I argue that due to the constitutionof GMF and the manner in which they areproduced, such foods are incompatible with thefundamental values and integrity of certainindividual moral agents or groups. I identifythree types of integrity that are threatened byGMF: religious, consumer, and integrity basedon certain other moral or metaphysical grounds.I maintain that these types of integrity aresufficiently important to provide justificationfor political and societal actions to protectthe interests of those affected. I conclude byproposing specific steps for handling GMFconsistent with the moral principles ofinformed consent, non-maleficence, and respectfor the integrity of all members of society.They include mandatory labeling of GMF, theimplementation of a system for control andregulations concerning such foods, andguaranteed provision of conventional foods.
