Laws,Defects and Countermeasures on the Circulation of Rural Housing Land——From the Perspective of Farmer Rights Protection

The thesis combs the existing legal provisions about rural housing land from the perspectives of use restriction,means restriction,subject restriction and mortgage prohibition,and finds out their defects,namely,weakening real right,confused knowledge about the integration of house property and land property,the loophole in Land Administration Law,the bans on the rural residents' purchase of housing land and so on.Then the thesis expounds the harms of restricting the circulation of housing land,for example,it will result in underground transaction of housing lands;lead to untenanted lands and waste of resources;bring about financing difficulty for peasants;do harm to the interest of land owners(rural collective economic organizations) and so on.The thesis further proposes to establish the legal lease model to solve the problems in the circulation of housing lands,specifically explains the definition of the legal lease model of housing lands,illustrates its detailed information from the aspects of object,subject and content and elaborates a series of problems involving,how to distribute the rent of housing lands,as well as how to perfect relevant procedures and formalities in the credit circulation of housing lands so as to realize the legitimate and effective circulation of rural housing lands and protect the peasants' interests.

Prediction of Farmland Protection Area in County-level Land Use Planning: A Case Study of Mizhi County of Shaanxi Province

Taking Mizhi County as an example and the year of 2005 as base period of planning,this paper made a prediction of farmland demand in 2010 and 2020 using grain security method,supply-demand balance method,and trend extrapolation method. In addition,it built a fixed weight combination model to make scientific summary of three prediction results. Finally,it predicted the farmland demand of Mizhi County in 2010 and 2020 will be 40 967 hm2 and 36 556 hm2,which can provide basis and reference for determination of farmland protection area in the land use planning.

Modes for Agricultural Land Protection in China

The main problem of agricultural land protection in China is the single farmland protection mode insuring arable land area only by issuing indicators,which brings great pressure to farmland's production and service function. Through establishing the corresponding relationship between food structure and some land use types,this paper points out that there is asymmetry between farmland area and per capita food consumption structure in China in recent years. Based on the above study,the paper proposes four types for agricultural land production, namely subsistence,fairly well-off,ecological and discrete type. Finally,it concludes that establishing rational type for agricultural land protection and implementing diverse farmland protection modes is the trend of farmland protection in China in the future.

Land Expropriation and Constitutional Protection of Farmers' Rights

One of the reasons for many social tragedies resulted from land expropriation in China is failure of the constitution to bring into play its due functions in standardizing land expropriation power of the government and protecting farmers' rights.In the existing land expropriation system,government is not only a policy maker of land expropriation,but also a "referee" of dispute over land expropriation.Government' land expropriation power and land-expropriated farmers' rights become out of balance.As a result,some local governments do not attach importance to farmers' rights,making land-expropriated farmers dissatisfied and consequently leading to some social tragedies unfavorable for harmony and stability.To fundamentally settle disputes over land expropriation and realize win-win of farmers' right and state interest,it should bring into full play functions of the constitution through protecting farmers' right to participate in land expropriation and establishing constitution evaluation mechanism.

Prediction and Protection of Cultivated Land in China

[Objectives]To protect cultivated land and ensure national food security and to forecast the cultivated land area of China and the provinces(cities)in 2030,2035 and 2050.[Methods]Based on the cultivated land area data of the whole country and provinces(autonomous regions and municipalities)from 2009 to 2017,the OLS model is used to forecast the cultivated land area of China and the provinces(cities)in 2030,2035 and 2050.[Results]The results show that the predicted area of cultivated land in 2030,2035 and 2050 is 134.0886,133.7856 and 132.8764 million ha,respectively,showing an obvious decreasing trend.The national cultivated land scale predicted in this paper can meet the requirements of the 2030 national cultivated land retention target set in the National Land Planning Outline(2016-2030).However,in the total area of existing cultivated land,there is still a certain area of sloping cultivated land(accounting for about 4%of the total cultivated land area,it is appropriate to gradually return farmland to forest).At the same time,nearly 20%of the cultivated land has been polluted,and the low-quality cultivated land accounts for about 22%of the total cultivated land.[Conclusions]The situation of cultivated land protection in the whole country is not rosy.For this reason,some measures and suggestions are put forward:strengthening land consolidation,striving to improve the quality of cultivated land,and appropriately increasing new cultivated land;strengthening the protection of cultivated land resources and strictly controlling the reduction of cultivated land.

Satellite monitoring of land-use and land-cover changes in northern Togo protected areas

Remote-sensing data for protected areas in northern Togo, obtained in three different years （2007, 2000, and 1987）, were used to assess and map changes in land cover and land use for this drought prone zone. The normalized difference vegetation index （NDVI） was applied to the images to map changes in vegetation. An unsupervised classification, followed by classes recoding, filtering, identifications, area computing and post-classification process were applied to the composite of the three years of NDVI images. Maximum likelihood classification was applied to the 2007 image （ETM＋2007） using a supervised classification process. Seven vegetation classes were defined from training data sets. The seven classes included the following biomes： riparian forest, dry forest, flooded vegetation, wooded savanna, fallows, parkland, and water. For these classes, the overall accuracy and the overall kappa statistic for the classi- fied map were 72.5% and 0.67, respectively. Data analyses indicated a great change in land resources; especially between 1987 and 2000 proba- bly due to the impact of democratization process social, economic, and political disorder from 1990. Wide-scale loss of vegetation occurred during this period. However, areas of vegetation clearing and regrowth were more visible between 2000 and 2007. The main source of confusion in the contingency matrix was due to heterogeneity within certain classes. It could also be due to spectral homogeneity among the classes. This research provides a baseline for future ecological landscape research and for the next management program in the area.

Urban Market-Gardening in Parakou (Republic of Benin): Spatial Dynamics, Food Security, Protection of the Environment and Creation of Employments

Nowadays, African cities are subjected to upsets which result from the extraordinary growth of urban populations. The growth of the population of cities has induced some changes in the structure of the activity of those cities. Agriculture which was formerly confined to the countryside henceforth develops in the urban area and occupies a preponderant place as a strategy of survival, of insertion and of food supplying of the city-dwellers. It has become an activity integrated to the urban tissue through systems of occupying and exploitation of land in the urban area. Population growth (4.81%) between 2002 and 2013 is a critical poverty rate (65%) of the population of Parakou city, entailing a misery perceptible in all its social and economic dimensions. The market-gardening activity has integrated itself to the urban tissue. The objective of this study is to understand how urban agriculture through market-gardening can be a solution for rural farmers who have moved to Parakou city. In this study, documentary research, interviews and field observation are used for data collection. The main results to be signaled among others are: evolution and status of the market-gardening areas in Parakou, the reduction of food insecurity with the permanent availability in quantity and in quality of market-gardening products accessible to the population: the protection of the environment through the drainage of the urban area and the preservation of the diversity of vegetables;the increase of the income of the households of the farmers and the creation of employments.

Land system reform should protect farmers' interests

|Editorial Note|Land has become an issue of increasing social concern as demand continues to surge in the midst of economic development,urbanization and industrialization.The crux of the issue is the land regime. China has a unique dualistic land regime under which the land market has not been well developed.Based on a review and commentary of the existing land polices,this article elaborates on the deficiencies inherent in China’s dualistic land rights system and land market and offers policy recommendations for promoting land system reform and market development.This study will help us gain an in-depth understanding of the problems in China’s land regime.

Analysis on the Relationship between Ecological Protection Red Line and Red Lines of Other Elements

Ecological protection red line is the minimum spatial area and territorial boundary line to be protected to realize the unification of economic,social and ecological benefits by increasing the national and regional ecological capital stock,maintaining ecological security,improving people's livelihood,promoting the sustainable development of economy and society,and upgrading the function of natural ecosystem.There are connections and differences between ecological protection red line and the red lines of cultivated land,forestry ecology,water resources control and marine ecology.Essentially speaking,they are all to maintain national ecological security and social stability,and create a good living environment for the people.

The Scale of Constructing Mountainous Cities in Yunnan Province based on “Benchmark” Farmlands

In 2011, Yunnan provincial committee and government proposed the strat- egy of constructing mountainous cities in order to protect farmlands and guarantee crop safety, which makes full use of hills and gentle-slopes and transforms land use pattern. However, social and economic development performs unevenly in Yun- nan, supplemented by varied geographical conditions, so that constructing mountain- ous cities should proceed as per local conditions. The research proposed the con- trol of constructing mountainous cities provided crop safety under the principle of farmland protection and measured the quantities of demanded construction lands ac- cording to science of population prediction and ekistics, based on which the control scales of constructing mountainous cities were determined by multiplying basic farm- land coefficient and the area of newly increased construction lands. The research is of significance for guiding the construction of mountainous cities and avoiding the occupation of construction lands on farmlands.

Interregional compensation for farmland protection:From the perspective of farmland allocation optimization

Interregional compensation for farmland protection(IRCFP)is a policy instrument for encouraging farmland protection through interregional fiscal transfer payments.Previous practices and studies on IRCFP have generally determined the payers and recipients of compensation based on the present distribution of farmland,and the compensation standards did not combine farmland development right value with farmland deficit and surplus,resulting in insignificant effects on farmland protection and even policy failure.Therefore,in this study,we proposed an interregional compensation mechanism for farmland protection based on farmland allocation optimization by considering 31 provincial-level regions in China.The results showed that(1)the determination of farmland surplus or deficit areas based on farmland allocation optimization met the regional construction land demand from the perspective of achieving food security.(2)The combination of the compensation value standard and cropland deficit and surplus had a positive effect on farmland protection.(3)Interregional compensation for farmland protection based on farmland allocation optimization can coordinate economic development,farmland protection,and ecological conservation.Finally,we discussed the rationality of interregional compensation for farmland protection based on farmland allocation optimization and designed the operation mechanism of IRCFP.

Spatial patterns and driving forces of land change in Tibetan-inhabited Three Rivers Headwaters region, China

The Three Rivers Headwaters Region(TRHR) plays a key role in regulating water supply and climate of East Asia. A comprehensive understanding of the processes and driving forces of the long-term land use dynamics of the TRHR is needed to guide sustainable land resource management and regional ecological conservation strategies. This study examined long-term land change patterns in the TRHR and investigated the driving forces of the change. First, Landsat TM/ETM+ images covering TRHR of four time points from 1987 to 2016 were used to derive land use patterns, and statistical metrics were applied to quantify the spatial and temporal changes. Second, Principal Component Analysis and correlation analysis were employed to analyze environmental and social-economic data to identify the driving forces of land use change. Third, potential influences of the religion of Tibetan Buddhism on land use change were explored using GIS analysis, questionnaire survey and field observation. Results showed that areas of barren land, agricultural land, and built-up land largely increased, while areas of grassland and forest greatly decreased, with the highest change rate occurring in the most recent decade of analysis(from 2007 to 2016). Among the three headwater regions, the Yellow River Headwater Region showed an overall higher changing speed than the other two headwater regions. The regional driving forces of change in TRHR includedsocial-economic development, climatic condition, pressure of population growth, and environmental protection activities. It was also found that Tibetan Buddhism can help slow down the changes caused by human activities.

An Ecocritical Interpretation of John Steinbeck＇ s Americans and the Land

The paper is intended to analyze John Steinbeck＇ s Americans and the land by the method of literary stylistics, which based on the theory of ecocriticism. The lexical choice, the syntactical structure and Steinbeck＇s ecological ideas can be revealed through the interpretation of his work. Between the lines, his deep love and pity for nature is all-around. What Steinbeck aspire for is the harmonious relationship between man and nature, and he appealed to human beings for protecting the living environment.
