我国野生蔬菜资源开发与利用 总被引:4,自引:0,他引:4
我国野生蔬菜种类繁多,资源十分丰富,它以无污染、营养、味道鲜美备受百姓喜爱。我国野生蔬菜利用的历史悠久,但多不成规模,并存在不少问题,资源未能得到充分合理的开发利用和保护。因此,必须扩展资源利用范围,合理开发、保护野生蔬菜资源,开辟野生蔬菜综合利用的新途径。 相似文献

Societies and social groups within them are becoming aware that food and fibre are not gifts of nature that come to us cost-free
from the natural world because their production involves consumption of renewable and non-renewable resources as well as expenses
for capital and variable inputs in the production process, plus outlays for transportation, processing, marketing, and food
preparation. The essence of food and fibre production is that on one hand, the key production resources (seeds, tubers, soil,
manures, and rain water) are renewable resources, thus potentially enabling agriculture to be a highly sustainable activity.
On the other hand, agriculture has some actual or potential characteristics of an extractive industry, similar to mining,
and accordingly has the potential to be highly unsustainable. In addition, food and fibre production may involve long-term
non-environmental costs (e.g. impacts on workers, communities, regions, and consumers) to a greater or lesser degree. In this
paper, I use the expression “societal costs” of agriculture to pertain to adverse impacts of agrofood systems on human health,
environmental quality, and the welfare and livelihoods of social groups. (A focus on the societal costs of food and fibre
production does not, of course, involve a presumption that the benefits of this production, both to humans and non-human portions
of the biosphere, are insignificant.) 相似文献

粮食和营养安全是当前全球关注的一项重要议题,预计到2050年全球人口将达到90亿,意味着需要通过继续增加粮食产量来解决日益复杂的粮食安全问题。与此同时减少从生产到消费整个供应链环节的食物损失浪费,以及通过食品加工为人类提高食品保存期限、营养质量以及食品安全也引起了极大的重视。本文通过文献梳理描述了初级食品生产系统的发展,以及食品加工对人类健康以及营养安全的作用。从未来的发展趋势来看,无论是农业生产部门还是食品加工部门都将面临用更少的资源来生产更多食品的问题。因而本文认为面对世界资源的日益紧张,必须对食品的能量和营养含量加以平衡,促进食品加工环节营养安全的提高,不失为一个良策。 相似文献

Effects of urbanization on arable land requirements in China, based on food consumption patterns 总被引:3,自引:0,他引:3
China’s urbanization has led to changes in food consumption patterns. The effects of this population shift on the limited arable land resources available have not been clearly understood. Based on food consumption data in 1982, 1992 and 2002, we evaluated the arable land requirements needed to meet the demand of Chinese food consumption patterns and the countermeasures that could mitigate the increasing pressure on this limited resource. The results indicated that processed food (including plant oil, alcohol and sugar) needed the most arable land for production, followed by livestock-based food and plant-based food, which needed the least. The arable land requirement for food consumption of urban residents was higher than that of rural residents in all 3 years, 1982, 1992 and 2002 and both decreased from 1982 to 2002. Based on the data for these years, the total arable land requirement for Chinese food consumption is projected to increase from 1982 to 2030, and then gradually decreases from 2040 to 2050. The food demand pressures put on the limited arable land resources in China is exacerbated by trends in food consumption patterns—i.e. more livestock-based and less plant-based food, and the need to improve the nutritional intake of both urban and rural populations. To alleviate the pressures, Chinese food consumption patterns should be changed so that less livestock-based and more plant-based food is consumed. Two other mitigation options are to increase the import of land-intensive food and to invest in agricultural research and development. These findings could be helpful in optimizing the interrelationships between the limited arable land resources available and food consumption patterns during the continuing rapid urbanization of China. 相似文献

Ritual practices from Christian and older animist belief systems persist across Timor-Leste (T-L). Significant events such as deaths and marriages include elements from both beliefs, and resources to conduct the associated ceremonies can affect agricultural production. In addition, ceremonies based on family lineage groups - lisan - are conducted for numerous purposes, with many related to food production and consumption. To investigate such rituals from a food security perspective, interviews on ritual practices were conducted in a longitudinal study among 18 households in four municipalities in 2006–2007 and among 56 respondents in three municipalities in 2015. Time and resources dedicated to ritual practices varied significantly across respondents, localities and crops. Despite extensive rural poverty, almost all communities dedicated significant resources and time to conduct ceremonies, particularly for maize and rice. Importantly, innovation in cropping was not stifled by rituals. Rituals reinforce social networks that have already been found to be important to food security, so in a broad sense rituals may even contribute to crop production. There was wide overlap between the composition of lineage lisan and mutual labour groups, which can be critical in T-L where, with limited availability of farm mechanization, the household unit of labour is insufficient for some agricultural tasks. A reallocation of resources from rituals to other objectives such as education and home maintenance is now gradually occurring. Looking ahead, respondents indicated that, while rituals could become less elaborate, continuance of the traditions was essential. Agricultural rituals contribute to the social capital needed for crop production and food security in T-L. 相似文献
