Book Description
News: Mao Yushi, one of China''s most outspoken and influential activists for individual rights and free markets, has been named the 2012 winner of the Cato Institute''s Milton Friedman Prize for Advancing Liberty . The objective of publishing this book is to let the general public have a better understanding of the food security situation in China and better comprehension of the merit of allocating land through market mechanism. In addition, it makes the public aware of the inefficiencies of current government regulated land system.As a populous country in the world, China emphasizes too much importance of food to ensure people''s sufficient consumption. There is a national policy to protect farm land, farm land protection refers to 18 hundred million mu of farmland which is specifically designated for food production only. Unirule defined the national food security as the capability to solve food shortages, and calculated the gap between food supply and demand. Two approaches can be used to solve the above food gap. Food security problems will not happen under situations of free trade and factors substitution in market economy, substantial storage and foreign exchange income. In modern China, food insecurity or great famine only happened in planned economy. To link tightly farm land size and grain yield and even food security is baseless both in theory and practices. The previous red line of 21 hundred million mu was already broken through. The current red line of 18 hundred million mu will also be broken through, in view of the process of industrialization and urbanization. In fact, farm land protection should focus on protecting the employment right of peasant in land.

Book Description
The alkaline igneous rocks and carbonatites are compositionally and mineralogically the most diverse of all igneous rocks and, apart from their scientific interest, are of major, and growing, economic importance. They are important repositories of certain metals and commodities, indeed the only significant sources of some of them, and include Nb, the rare earths, Cu, V, diamond, phosphate, vermiculite, bauxite, raw materials for the manufacture of ceramics, and potentially Th and U. The economic potential of these rocks is now widely appreciated, particularly since the commencement of the mining of the Palabora carbonatite for copper and a host of valuable by-products. Similarly, the crucial economic dominance of rare earth production from carbonatite-related occurrences in China, has stimulated the world-wide hunt for similar deposits. This volume describes and provides ready access to the literature for all known occurrences of alkaline igneous rocks and carbonatites of Antarctica, Asia and Europe excluding the former USSR, Australasia and oceanic islands. More than 1,200 occurrences from 59 countries are outlined together with those of 57 oceanic islands and island groups. The descriptions include geographical coordinates and information on general geology, rock types, petrography, mineralogy, age and economic aspects with the principal references cited. There are 429 geological and distribution maps and a locality index. As has been demonstrated by the three earlier volumes, the present book is likely to be of considerable interest to mineral exploration companies, as there are no comprehensive published reviews of the economic aspects of the alkaline rocks. It will also interest research scientists in the fields of igneous petrology and volcanology, and geologists concerned with the regional distribution of igneous rocks and their geodynamic relationships.
