Organic carbon source and burial during the past one hundred years in Jiaozhou Bay, North China

Organic carbon (OC), total nitrogen (TN), and Pb-210 in core sediment were measured to quantify the burial of organic carbon and the relative importance of allochthonous and autochthonous contributions during the past one hundred years in Jiaozhou Bay, North China. The core sediment was dated using Pb-210 chronology, which is the most promising method for estimation of sedimentation rate on a time scale of 100-150 years. The variation of the burial flux of organic carbon in the past one hundred years can be divided into the following three stages: (1) relatively steady before 1980s; (2) increasing rapidly from the 1980s to a peak in the 1990s, and (3) decreasing from the 1990s to the present. The change is consistent with the amount of solid waste and sewage emptied into the bay. The OC:TN ratio was used to evaluate the source of organic carbon in the Jiaozhou Bay sediment. In the inner bay and bay mouth, the organic carbon was the main contributor from terrestrial sources, whereas only about half of organic carbon was contributed from terrestrial source in the outer bay. In the inner bay, the terrestrial source of organic carbon showed a steady change with an increase in the range of 69%-77% before 1990 to 93% in 2000, and then decreased from 2000 because of the decrease in the terrestrial input. In the bay mouth, the percentage of organic carbon from land reached the highest value with 94% in 1994. In the outer bay, the sediment source maintained steady for the past one hundred years.

GSP+ and Human Rights::Is the EU's Approach the Right One?

Among the purposes of the EU’s GSP+ programme is to link human rights to trade incentives, with the idea of using such incentives to promote developing countries’ adoption of the values found in core human rights treaties. With the re-renewal of the GSP (and GSP+) programmes to take effect in January 2014, it is fruitful to examine their efficacy and consistency with WTO law. In this article, I argue the GSP+ programme is not only ineffective in obtaining an improvement in human rights conditions for the vast majority of the world’s population, but it is also incompatible with WTO law. A stick-based regime where human rights abuses are linked to trade sanctions is a better way to proceed. After outlining the GSP+ system, and its linkage of human rights and trade, I analyse its efficacy and WTO consistency. Having shown that it is ineffective and contrary to WTO law, I argue that trade sanctions based on a PPM distinction and/or GATT XX(a) may be the appropriate means of linking trade and human rights. The article ends with some concluding remarks on the need for the careful design of such a system.
