Does tenure security matter? : rural household responses to land tenure reforms in northwest China

Het hoofddoel van China’s landbouw- en plattelandsbeleid is behoud van voedselzekerheid in eigen land en bijdragen aan de voedselzekerheid in de wereld door duurzaam gebruik van natuurlijke hulpbronnen en verbetering van de landbouwproductiecapaciteit voor de lange termijn. In veel gebieden in China gaat de landbouwproductiecapaciteit op lange termijn echter achteruit door intensieve landbouw en de daarmee gepaard gaande degradatie van de hulpbronnen land en water. Het systeem van grondeigendom speelt, als fundamentele institutie die het gedrag van grondbezitters aanstuurt, een zeer belangrijke rol bij de landbouwproductie alsook bij het gebruik van natuurlijke hulpbronnen, en heeft veel belangstelling genoten van onderzoekers in China en andere regio’s in de wereld. Sinds 1998 heeft de Chinese regering een reeks marktgeoriënteerde hervormingen in het grondeigendom ingevoerd die als doel hebben de eigendomszekerheid te verbeteren en de overdraagbaarheid van rurale grond te bevorderen. Relevante wetten behelzen de Wet Grondbeheer (Land Administration Law) uit 1998, de Wet Contracten Rurale Grond (Rural Land Contract Law) uit 2002, de Eigendomswet (Property Law) uit 2007, en de Wet Mediation en Arbitrage bij Geschillen inzake Contracten Rurale Grond (Mediation and Arbitration of Rural Land Contract Disputes Law) uit 2009. Ofschoon deze hervormingen bijgedragen hebben aan een verbeterde formele eigendomszekerheid, is het niet duidelijk in welke mate ze bijdragen aan landbouwproductie en duurzaam gebruik van de grond. In deze studie worden systematisch de relaties onderzocht tussen grondeigendomszekerheid, zoals die wordt beïnvloed door de recente marktgeoriënteerde eigendomshervormingen, en de landbouwproductie in China. Op basis van de bestaande literatuur worden er vier relaties onderzocht, namelijk de relaties tussen eigendomszekerheid en, respectievelijk, grondinvesteringen, marktontwikkelingen betreffende grondpacht, ruraal-urbane migratie, en landbouwproductiviteit en technische efficiëntie. De resultaten van de studie beogen een volledig beeld te verschaffen van de belangrijkste relaties tussen grondeigendomszekerheid, beslissingen op het niveau van huishoudingen, en de landbouwproductiviteit in China. Naar verwachting zullen de verkregen inzichten relevant zijn voor de voortgaande hervormingen van het rurale grondeigendomsysteem en voor gerelateerd landbouw- en plattelandsbeleid in China. Ze zouden tevens van nut kunnen blijken voor andere ontwikkelingslanden met vergelijkbare eigendomsystemen die als doel hebben om huishoudens op het platteland te voorzien van gewaarborgde formele landgebruiksrechten voor de lange termijn

Structure, mechanical properties and degradation behavior of electrospun PEEU fiber meshes and films

The capability of a degradable implant to provide mechanical support depends on its degradation behavior. Hydrolytic degradation was studied for a polyesteretherurethane (PEEU70), which consists of poly(p-dioxanone) (PPDO) and poly(epsilon-caprolactone) (PCL) segments with a weight ratio of 70:30 linked by diurethane junction units. PEEU70 samples prepared in the form of meshes with average fiber diameters of 1.5 mu m (mesh1.5) and 1.2 mu m (mesh1.2), and films were sterilized and incubated in PBS at 37 degrees C with 5 vol% CO2 supply for 1 to 6 weeks. Degradation features, such as cracks or wrinkles, became apparent from week 4 for all samples. Mass loss was found to be 11 wt%, 6 wt%, and 4 wt% for mesh1.2, mesh1.5, and films at week 6. The elongation at break decreased to under 20% in two weeks for mesh1.2. In case of the other two samples, this level of degradation was achieved after 4 weeks. The weight average molecular weight of both PEEU70 mesh and film samples decreased to below 30 kg/mol when elongation at break dropped below 20%. The time period of sustained mechanical stability of PEEU70-based meshes depends on the fiber diameter and molecular weight

Land tenure reforms and land conservation investments in China – what does real option value theory tell us?

Land conservation investments can make an important contribution to avoidance and mitigation of land degradation. Lack of tenure security and land transferability may, however, limit the extent to which farmers undertake such investments. Using real option value theory, this paper investigates the expected impact of the market-oriented tenure reforms in China since 1998 on land conservation investment incentives. It postulates that the reforms are more likely to elicit land conservation investments in areas where land markets are developing. This paper further argues benefits of the land tenure reforms will be underestimated if only the intrinsic but not the time value of changes in the investment incentives will be considered. The findings obtained from this research provide a better understanding of the relationship between the land tenure reforms and land conservation investments, and are likely to serve sustainable land management in China and elsewhere

An economic-psychological perspective on perceived land tenure security : Evidence from rural eastern China

Land tenure security perceived by farmers is generally considered an important precondition for rural development. In this paper, we first propose a holistic framework of land tenure security that integrates Van Gelder's tripartite view of tenure security with Ho's credibility thesis. Following this framework, we empirically investigate the interrelation between the cognitive and the affective components of tenure security perceptions, and analyze how these perceptions are influenced by psychological factors, such as personality traits and economic preferences. We apply the generalized structural equation modeling to a dataset collected in 2019 among 1359 rice farmers in three provinces in eastern China. We found that the cognitive component shows an inverse “U-shape” relationship with the affective component, indicating farmers are not necessarily worried about the possible future land reallocation even if they think it is very likely to take place and that the widely used indicator, i.e., estimated probability of land reallocation, is thereby not sufficient to reflect a farmer's overall perceived tenure security. We also found that individual differences in personality traits (e.g., neuroticism) can help explain observed variations in perceived tenure security. The results showing perceived land tenure security of rural farmers also comprises nonequivalent “feeling” and “thinking” components and their influencing psychological factors have important implications for future research and policy making on rural institutional development

Land tenure security and technical efficiency : New insights from a case study in Northwest China

Improving technical efficiency in agriculture can play an important role in meeting present and future demands for agricultural products, at the same time enhancing the long-term sustainability of land and water use. This paper examines the impact of household perceptions of land tenure security on technical efficiency using detailed household-level data collected in Minle County in northwest China. The authors find that the (perceived) tenure security provided by land certificates encourages part-time farming with relatively low technical efficiency. The renting out of land by households with migrant members can only partly make up for this negative effect, because land rental markets are thin and highly fragmented. Therefore, the provision of land certificates to rural households has a negative impact on technical efficiency. For tenure security provided by the expected absence of land reallocations in the near future, on the other hand, the authors find that it reduces temporary migration and thereby contributes to higher technical efficiency.</p

Farmland Dispute Prevention: The Role of Land Titling, Social Capital and Household Capability

Disputes over farmland constitute an important challenge for tenure security, economic growth and social stability. Land titling is a theoretically promising policy instrument that can enhance tenure security and reduce the occurrence of farmland disputes in the developing world. However, the impact of land titling on the occurrence of disputes has been found to be highly conditional. Empirical evidence on this issue has been surprisingly limited and has often lacked the consideration of a specific context. In this study, whether land titling affects the incidence of farmland disputes in the context of China is investigated, focusing particularly on the interaction between land titling and social capital and household capability. Both the probit and CLL models are applied, using household data entailing a total of 3693 samples located in rural China. The results show that (1) land titling in China reduces the incidence of farmland disputes, and that (2) the analysis based on interaction terms indicates that households who are disadvantaged in social capital and household capability are more likely to experience fewer disputes. Implications for the government and organizations are as follows: (1) the titling programme should seriously consider the current tenure arrangement. Confirmation of current tenure is recommended over the establishment of a new system to avoid possible institutional shopping and overlapping claims; and (2) land titling, if well implemented, is recommended to redress local power asymmetry and to help vulnerable groups defend their property
