Problems in Rural Land Management Right Confirmation Pilots and the Countermeasures

The affirmation registration and certification of land contracted management right are the essential conditions for the effective promotion of land management right circulation and the development of agricultural moderate scale management. However, the following problems are found in the process of the pilot work： insufficient propaganda work, inconsistent recognition of affirmation registration work, low enthusiasm of grass-roots work; lack of unified regulations, each company working on their own; requiring large amount of manpower and resources for rural land contracted management rights, and severe shortage of national and municipal inputs; incomplete land ownership information and lack of marks between land plots, leading to resolving difficulty of the disputes; urgent need of strengthening subsequent work, untimely adjustment of related policies. Therefore, it needs to intensify propaganda, so that farmers can know the land right confirmation registration and certifi- cation, and recognize its importance; unify the introduction of job specification and results storage standard, making it convenient for the unified use of the results unified; set up special funds, and make experiments first in the areas with better economic conditions; establish arbitral institutions for land ownership disputes; earnestly make great effort to the supporting and subsequent work for right confirmation registration, and give full play to the role of land registration results.

Spatial and Temporal Variability of Farm Size in China in Context of Rapid Urbanization

During the last 30 years, China has witnessed rapid economic growth and dramatic urbanization, with about 1.2 x 107 rural people migrating annually into urban areas. Meanwhile, especially since 1995, the rural population has been declining, which is closely linked to land circulation and the increase in farm size in many villages. Increasing scale of farming operations is often regarded as a key to avoiding the abandonment of farmland and to increasing the income of rural farmers. However, until now, there has been little research on the spatial and temporal variability of farm size at the national level in China. Using data from the national agricultural cen- sus and rural household surveys, this study examines the characteristics of land use circulation and the consequent changes in the area of farmland per household. The results show that： 1） 12.2% of rural households were involved in land circulation at the national level. The highest amounts of land circulation have occurred in those provinces where the farmland per capita is more than 0.2 ha or less than 0.1 ha; 2） over 80% of households operate less than 0.6 ha of farmland; 3） the proportion of mid-sized farms （between 0.2 ha and 0.6 ha per household） has decreased while the smallest and the largest farms have increased. This bears some similarity with the phenomenon known as the ＇disappearing middle＇, referring to the changes in farm size. This study establishes a framework for interpreting the factors affecting the changes in farm size in China, which include two promoting factors （urbanization and agriculture） and four hindering fac- tors （agricultual land system, household registration, stable clan system, and farmland loss）.

Comparison of Artificial Neural Networks,Geographically Weighted Regression and Cokriging Methods for Predicting the Spatial Distribution of Soil Macronutrients(N,P,and K)

Soil macronutrients(i.e. nitrogen(N), phosphorus(P), and potassium(K)) are important soils components and knowing the spatial distribution of these parameters are necessary at precision agriculture. The purpose of this study was to evaluate the feasibility of different methods such as artificial neural networks(ANN) and two geostatistical methods(geographically weighted regression(GWR) and cokriging(CK)) to estimate N, P and K contents. For this purpose, soil samples were taken from topsoil(0–30 cm) at 106 points and analyzed for their chemical and physical parameters. These data were divided into calibration(n = 84) and validation(n = 22). Chemical and physical variables including clay, p H and organic carbon(OC) were used as auxiliary soil variables to estimate the N, P and K contents. Results showed that the ANN model(with coefficient of determination R^2 = 0.922 and root mean square error RMSE = 0.0079%) was more accurate compared to the CK model(with R^2 = 0.612 and RMSE = 0.0094%), and the GWR model(with R^2 = 0.872 and RMSE = 0.0089%) to estimate the N variable. The ANN model estimated the P with the RMSE of 3.630 ppm, which was respectively 28.93% and 20.00% less than the RMSE of 4.680 ppm and 4.357 ppm from the CK and GWR models. The estimated K by CK, GWR and ANN models have the RMSE of 76.794 ppm, 75.790 ppm and 52.484 ppm. Results indicated that the performance of the CK model for estimation of macro nutrients(N, P and K) was slightly lower than the GWR model. Also, the accuracy of the ANN model was higher than CK and GWR models, which proved to be more effective and reliable methods for estimating macro nutrients.

Study on the Rual Migrant Workers＇ Willingness to Have Urban Hukou and the Choice of Urbanization Path of China in Recent Years

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.

Analysis of Household Management Behavior in the Reclamation and Agricultural Area under Different Land Systems

In the paper, three farms of Jiansanjiang Farming Bureau and five villages in of Dayushu Town in Fujin county randomly were taken as data sources for the investigation of household behavior of reclamation and agricultural area under different land systems, and it can be concluded that the main content included production scale, arable land use structure, household behavior and economic benefits. By comparison and analysis, the advantages and disadvantages of reclamation and agricultural area can be found, which could provide references for agricultural land reform for achieving a more suitable socio-economic of efficient use and sustained and healthy development of agriculture.

Research on Chinese rural land management model of scale and development prospects

In the early years of reform and opening up, with the household contract management as the core, the land reform has been adapted to the prevailing agricultural productivity development and management level, achieved to mobilize the peasants＇ production enthusiasm and creativity, to improve production efficiency, basically solved the food and clothing problem; but it has formed small-scale decentralized business model. With the rapid development of the rural economy, along with urbanization and industrialization, it has been further increased the degree of market-oriented agriculture. The contradiction between big market and small-scale production is more prominent; such small -scale decentralized form of management has begun not to meet agricultural development request and the market economy development. It needs changes to moderate scale. Eleventh Five-Year Plan and construction of new socialist village require clearly various forms of appropriate scale.

Social progress for the exploration of reform in the rural management system research

Combining with the third plenary session of the 17th ＂the central committee of the communist party of China on promoting rural reform and development of certain major issue decision＂ and the eighteenth big clear adherence to and improve the basic rural operation system and to protect farmer＇ s right to the contracted management of land, the land and collective income distribution, the resolution of collective economic power, this paper discusses the main content of deepening reform of China＇ s basic rural operation system. It elaborates we must adhere to stabilize and improve the rural basic management systems, give farmers more fully right to protect the land, develop rural land contract management rights transfer, and promote agricultural innovation and industrial organization.

The Legal Dilemma of the Financialization of Agricultural Land and a Way Forward

The strict limits on the financialization of agricultural land in the current legal system impede the development of rural finance. Objective needs have driven local governments＇ exploration of different modes of financialization, providing samples we can analyze in connection with the next steps in institutional development. The financialization of agricultural land arises naturally from its nature as an asset. Whether one acknowledges the land＇s social security function does not affect its financialization. In institutional rebuilding, the particular character of mortgages on agricultural land should be considered. The mortgage-holder must be a financial organization, not a natural person or an ordinary finn. The person mortgaging the right to operate the land under the contract responsibility system need not have a stable non-agricultural occupation or stable source of income, or the consent of the party issuing the contract. Registration constitutes public notification of the setting up of a mortgage and is also the condition whereby it comes into effect. The mortgage cannot be realized by means of discounting, but compulsory management can be used to subcontractor let the relevant agricultural land. The debt can then be liquidated from this income and the land returned to the mortgagor.
