The Revival of Private Property and Its Limits in Post-Mao China

This monograph examines the nature and significance of the re-emergence of private property in rapidly changing post-Mao China.

In examining this issue, the study explores a key dichotomy in Chinese law, that is, ‘public versus private’, and examines the manner in which the Chinese define ownership. The study stresses the importance of lack of clarity in the boundaries between the public and the private in property rights.

While there is a limited move towards the recognition of private property in real estate in contemporary China, this analysis also shows that ownership in the law, and ownership as understood and practised socially, often diverge significantly.

From the Qing dynasty reforms of the late nineteenth century onwards, ‘modernist’ law and entrenched social practice have often opposed each other. In contrast to the official, and indeed legal, support for unitary and exclusive property rights, the reality of the property regime has been a fragmentation of property rights. ‘Modern’ conceptions and theories of property rights emerged in the context of nation-building from the late Qing onwards, and unitary and exclusive property rights were considered as ‘badges’ of modernity.

These conceptions and theories served (and still serve) the purposes of control and governance but were, and still are, often resisted in social practice and popular thinking, leading to alienation and conflict. As a result, analysis of the nature and the social and political implications of re-emerging private property rights provides important insights for our understanding of the changing nature of modern China.

Environmental and genetic control of arsenic accumulation and speciation in rice grain:comparing a range of common cultivars grown in contaminated sites across Bangladesh, China, and India

The concentration of arsenic (As) in rice grains has been identified as a risk to human health. The high proportion of inorganic species of As (As(i)) is of particular concern as it is a nonthreshold, class 1 human carcinogen. To be able to breed rice with low grain As, an understanding of genetic variation and the effect of different environments on genetic variation is needed. In this study, 13 cultivars grown at two field sites each in Bangladesh, India, and China are evaluated for grain As. There was a significant site, genotype, and site by genotype interaction for total grain As. Correlations were observed only between sites in Bangladesh and India, not between countries or within the Chinese sites. For seven cultivars the As was speciated which revealed significant effects of site, genotype, and site by genotype interaction for percentage As(i). Breeding low grain As cultivars that will have consistently low grain As and low As(i), over multiple environments using traditional breeding approaches may be difficult, although CT9993-5-10-1-M, Lemont, Azucena, and Te-qing in general had low grain As across the field sites.

Occurrence and Partitioning of Cadmium, Arsenic and Lead in Mine Impacted Paddy Rice: Hunan, China

Paddy rice has been likened to nictiana sp in its ability to scavenge cadmium (Cd) from soil, whereas arsenic (As) accumulation is commonly an order of magnitude higher than in other cereal crops. In areas such as those found in parts of Hunan province in south central China, base-metal mining activities and rice farming coexist. Therefore there is a considerable likelihood that lead (Pb), in addition to Cd and As, will accumulate in rice grown in parts of this region above levels suitable for human consumption. To test this hypothesis, a widespread provincial survey of rice from mine spoilt paddies (n = 100), in addition to a follow-up market grain survey (n = 122) conducted in mine impacted areas was undertaken to determine the safety of local rice supply networks. Furthermore, a specific Cd, As, and Pb biogeochemical survey of paddy soil and rice was conducted within southern China, targeting sites impacted by mining of varying intensities to calibrate rice metal(loid) transfer models and transfer factors that can be used to predict tissue loading. Results revealed a number of highly significant correlations between shoot, husk, bran, and endosperm rice tissue fractions and that rice from mining areas was enriched in Cd, As, and Pb. Sixty-five, 50, and 34% of all the mine-impacted field rice was predicted to fail national food standards for Cd, As, and Pb, respectively. Although, not as elevated as the grains from the mine-impacted field survey, it was demonstrated that metal(loid) tainted rice was entering food supply chains intended for direct human consumption.
