The implementation of pasture contracting policies in the Tibetan Plateau has been of widespread concern in the scientific community and related government departments. Studying the effects of the implementation of pasture contracting policies will help us understand herders' attitudes toward those policies and to amend existing policies effectively.This paper analyzes 135 herder families' grazing management behavior using participatory rural appraisal(PRA), quantitative analysis and a Logistic regression model in three townships of Nagqu County in remote areas of the Tibetan Plateau, China. The results show that the herders have become settled and are no longer nomadic, so the settlement project has basically been completed and the policy of contracting for grazing rights is being gradually implemented in Nagqu County. Since the grazing rights and pastures were under contract, group-based management has been widely accepted in this area, which helps the herders deal with constraints, such as limited pasture area, a small grazing radius, controlled family animal husbandry and an uneven distribution of water. The herders that have more family members available for labor, higher proportion of family members with good health, and higher income from animal husbandry tend to choose household-based management.Herders tend to choose group-based management when higher quality winter pastures are available. 展开更多

The colonization of Sicilian latifundium was an attempt of regeneration of the rural areas. It was carried out by Benito Mussolini, called II Duce, who governed Italy by a regime with an absolute and conservative approach for 20 years since 1922. According to this plan, there were some rural villages (with a school, a church, a police station and a doctor's surgery) and a number of rural homes, spread in the landscape, that formed one of the most important achievements of the agrarian reform in Italy. The author has been conducting scientific research on this topic for several years. He started with the archive "Ente per la Colonizzazione del Latifondo Siciliano" (now called Ente Sviluppo Agricolo) to review the original designs and contracts with companies, ledgers and other administrative documents. Lately, he has been reviewing the personal archives of designers involved in the building program, where he has found original drawings, letters, sketches, etc.. He has also conducted some architectonic and technical surveys of the sites. We have to consider that nowadays the mentioned rural villages are a strategic resource for the development of the neighboring areas, as it may become a network for the sustainable tourism and the promotion of the local agro food specialties. On this purpose, the local authority is going to promote some plans for the requalification of these sites. The particular achievement of this article is to show a number of possibilities for the reuse of these places. 展开更多

Based on the empirically analysis of the data from a nationwide survey in 2010 in China, the study found. (1) The overwhelming majority of rural migrant workers in China were not willing to convert their rural household registration (nongye hukou) to an urban or non-rural registration Orei nong hukou). If they were required to return the rural land contract rights as precondition, only lOper cent were willing to be urban citizens. (2) For the small proportion of migrant workers who were willing to convert their rural household registration to urban household registration, 'obtaining access to better education and more opportunities for the continuation of education for their children' is the major incentive. (3) The primary reason for retaining a rural hukou, on the other hand, is to keep their rural contract land. (4) Finally, there is no significant difference between the rural migrant workers who were born before 1980 and those after 1980, in term of the attitude toward converting rural hukou to urban hukou. The policy recommendations drew from the findings are as follows: 1) In order to promote the urbanization process, the government should choose the path of 'urbanization based on the long term residence in the towns and cities' instead of the path of "urbanization based on household registration '. 2) The rural migrant workers should be converted into urban citizens without being forced to give up their contact land. 3) The government should give equal weight in policy making to the migrant workers born before 1980 and those born after 1980. Therefore, the policy emphasis of deepening the urbanization of China should focus on the 'equalization of the resource allocation of the public services and social welfare" while the characteristics of the separation of the household registration system should not be strengthened any longer. 展开更多
