In the early 1970s, there was scarcity in the world grain market, soaring prices and famines in several countries of Asia and Africa. The commercial grain trade was expanded at the expense of food aid. After a brief look at policies addressing the situation in terms of modernised methods of agricultural production for small producers, the article sketches how such policies also affected relief efforts, from the low availability for food aid, the provision of food that was not useful and late deliveries through efforts to tie food aid to local changes in agricultural production and settlement patterns. In part, food aid thus reinforced processes of social differentiation that had contributed to causing the famines in the first place.  相似文献

Samples of ancient Indian lime plaster have not previously been analysed. Excavation of a seventh century AD baked brick structure provided the necessary samples for a detailed laboratory examination of plaster. The plaster samples were studied by chemical and petrographic methods. The probable sources of lime and sand were indicated by the mineralogy.  相似文献

在英国王室珍藏(The Royal Collection)收藏的中国瓷器有着近五百年的历史,这其中既包括外销瓷,也包括赏赉瓷器,而最难得瓷器珍品则是乾隆皇帝与慈禧太后赠送给英国君王的外交礼品用瓷。通过对英国王室珍藏初步的观察与判断,可以看出其反映了清代中英外交与贸易关系的变化,侧面反映了十八之十九世纪清朝由盛转衰的历史。  相似文献

Starch grains from 31 modern samples of millets derived from the seeds of 7 species within the genus Setaria and 2 species within the genus Panicum were analyzed to determine diagnostic morphological characteristics. Ancient starch grains recovered from a sample of broomcorn millet (Panicum miliaceum) excavated from the Cishan site (10.0-7.6 cal yr BP) in the North China Plain were then subjected to the same analyses to determine the differences in morphologies, if any, between modern and ancient samples. The data indicate that morphological features, and particularly surface and fissure features, will allow for solid identifications of ancient millet starches, while size classes will be helpful, but will not be dependable taxonomic indicators.  相似文献

Prehispanic corporate social units in northern Peru, the pachacas or ayllus and the guarangas, continued to structure social life in Cajamarca throughout the Spanish colonial period. They were restructured by Spanish rule, as they had been by the Inca conquest before. Spanish rule also reshaped indigenous migration and the social categorization of the migrants, which was closely intertwined with the regime of land tenure. This article takes a look at the integration of new and old migrants and their descendants into the local social structure and examines how they negotiated their belonging in petitions to change or defend their fuero. The petitioners successfully argued on the basis of their ancestry, whether legitimate or not, and activated personal networks on their behalf. In that, they paralleled mestizo and mulatto petitioners who, like migrants, benefited from fiscal prerogatives, which were however challenged during the course of the 18th century, leading to a partial re-categorization. The redistribution of land was an important motive in these late colonial re-categorizations, but also earlier in the colonial period the absence of bonds to the land was an essential characteristic of being categorized as a ‘migrant.’  相似文献

华北沦陷区粮食的生产与流通   总被引:2,自引:0,他引:2  
王士花 《史学月刊》2006,2(11):55-63
抗日战争时期,日伪特别重视对华北沦陷区粮食的掠夺。尽管在太平洋战争爆发前更重视棉花的增产,但除日伪强力推行植棉的地区外,华北沦陷区的农民仍以种植粮食作为农耕的第一选择。日本的军事侵略及统治,严重破坏了农村的农业生产力,粮食的播种面积及单产量都比七七事变前减少,粮食的流通渠道、机构、方向、手段等都受到了影响。粮食流通的初级市场———集市减少,农民多在自家庭院卖给前来收购的小贩;一些粮栈或货栈成为日本商社的收购人;大城市粮栈的运输职能丧失;一些粮食集散市场的中转职能改变;铁路、卡车及牲畜运输量的增加,也从一个侧面反映了日伪交通统制的重点和薄弱环节所在。  相似文献

试论抗战时期国民政府的粮食供应与配给   总被引:1,自引:0,他引:1  
陈雷 《安徽史学》2010,(6):71-76
抗战时期,为了支持抗战,维持军心民心,确保国统区人民生活的基本稳定,国民政府在实施田赋征实的基础上对全国军公民粮实行定量供应和配给。这一战时特殊粮食统制措施的实施,保障了抗战后期军粮民食的供应,稳定了后方社会秩序,成效较为明显,为坚持抗战作出了一定贡献。  相似文献
