Smallholder participation in the land rental market in a mountainous region of Southern China: Impact of population aging,land tenure security and ethnicity

Rural land rental markets in China play an increasingly important role in the transformation of the agricultural sector. This study focuses on the rural land rental market in the Xishuangbanna Dai Autonomous Prefecture in Southern China, a mountainous region, where rapid changes in land use have taken place with the transition from traditional agriculture and a tropical rainforest to rubber monoculture. Notably, we assess the impacts of population aging, land tenure security, and ethnicity on the participation of smallholders in the land rental market. The analysis suggests that a higher proportion of older people in a household increases the likelihood of renting out land and reduces the probability of renting in land, implying that population aging fosters land rental market development by transferring land from older to younger farmers. We also confirm that the availability of a land tenure certificate has a significant and positive impact on the renting out of land. Furthermore, ethnic minority groups are less likely to rent out land, indicating that land rental markets are ethnic sensitive. Additionally, specialization in rubber farming, household wealth and the altitude of household location also influence participation in the land rental market.     

Tenure Security and Farm Efficiency Analysis Correcting for Biases from Observed and Unobserved Variables: Evidence from Benin

We analyse the impact of land tenure security on the technical efficiency of a sample of smallholder farmers in Benin, based on an output‐oriented stochastic distance function. We use propensity score matching to correct for selection bias from observed variables. The Greene ( 2010 ) sample selection model is used to correct for selection bias due to unobserved variables. We estimate meta‐frontiers to analyse agricultural productivity and efficiency differences between landowners and non‐owners. Our results show that non‐owners have consistently higher levels of technical efficiency and productivity.     

Land tenure and rental in Western Sudan

This paper reports on aspects of land tenure in western Sudan, especially the nature of tenure insecurity and the functioning of the land rental market. The active land rental market accounted for about one-third of cultivated land. Patterns of land rental transactions, and tests of the importance of insecurity in renting land, where the owner may not be able to reclaim land rented out, do not support the presumption that rental markets perform poorly. The role of the sheikh as administrator of village land, and the claims of large landowners to vast tracts, are, however, important political problems that must be resolved before attempts at ‘rationalizing’ land tenure.     

Livestock and land share contracts in a Hindu society

This article examines factors related to a livestock rental market in western Nepal and assesses whether this market is associated with caste differentiation and land rental market participation. Theoretical models for asset‐rich (i.e., high‐caste) households, rich in land and livestock, and asset‐poor (i.e., low‐caste families) households are presented to provide logical explanations for the existence of a livestock rental market and the synergy between livestock and land rental markets participation. A combination of double hurdle models and bivariate‐ordered probit models were used to test the implications of the models. Consistent with the theoretical models, land‐ and livestock‐rich high‐caste households were more likely to rent out land and/or livestock, whereas land‐ and livestock‐poor and credit constrained low‐caste households were more likely to rent livestock and land from others. Participation in the two markets was positively correlated, indicating a synergistic relationship that may be due to production and transaction costs reducing benefits. Policies that can enhance the allocative efficiency of livestock and land rental markets can improve equity as well as efficiency of land use in Nepal. Provision of livestock credit to land‐poor low‐caste households is also crucially dependent on their access to more long‐term contracts for land.     

Localizing Land Governance,Strengthening the State: Decentralization and Land Tenure Security in Uganda

Decentralization of land governance is expected to significantly improve land tenure security of small‐scale farmers in Africa, through ensuring better protection of their assets and reducing land‐related conflicts. This paper, however, cautions not to have too high expectations of transferring responsibilities for land administration and dispute resolution to local government bodies. Field research in Mbarara District in south‐western Uganda brings out how decentralization has limited impacts in terms of localizing land services provision. Nonetheless, local land governance has transformed in important ways, as decentralization adds to institutional multiplicity, and fuels competition among state and non‐state authorities, and about the rules they apply. Rather than strengthening local mechanisms for securing tenure, the reforms introduce new forms of tenure insecurity, fail to transform local conventions of dealing with land disputes and delegitimize local mechanisms for securing tenure. In practice, decentralization has had limited effects in securing tenure for the rural poor, yet reinforces the presence of the state at the local level in diverse ways.     

Tenure,land rights,and farmer investment incentives in China

The goal of this paper is to understand the nature of the property rights associated with China's land tenure systems and to study the impact of these property rights on agricultural production efficiency. The results show that land tenure and associated property rights in rural China affect the production behavior of farmers. The most robust finding is that the right to use land for long periods of time encourages the use of land-saving investments. While the results show that land tenure affects agricultural production decisions, the difference between collective and private plots, however, is small compared to the private plot - communal productivity gap that existed in the pre-reform period.

Land Tenure and Tenure Regimes in Mexico: An Overview

This article provides an overview of the evolution of land tenure and tenure regimes in rural Mexico from colonial times to the present. It shows how, by the late nineteenth century, the dual system of indigenous communal tenure and Spanish and criollo landholdings was undermined by liberal legislation that sought to privatize community lands. This resulted in a process of disappropriation and concentration of land in a few hands, which created the setting for rural upheaval during the Mexican revolution and for the subsequent redistributive land reform and the creation of a 'social sector' consisting of ejidos and agrarian communities. By the 1960s, however, the reform sector began to enter into crisis. A reform of the Constitution and new agrarian legislation of 1992 opened the way to privatization of land in the social sector, expecting that this would dynamize production. It is shown that this has not been the case. In a context of globalization and asymmetric free-trade relations the crisis has only deepened.

The roles of risk preferences,selection, and uncertain returns on land contracts

Using panel data on a statistically representative sample of Iowa farmland parcels from 1997 to 2017, we analyze the factors determining whether land is farmed by the owner or rented out under a cash rent or crop share contract. The landowner's decision to rent or operate the land depends on the distribution of expected net returns to the land, and so estimates of the factors affecting rental terms will be biased if the sample only includes rental contracts and excludes the owner-operator. Land with higher mean and/or lower variance of expected net returns is most likely to be rented out. Participants in the rental market will include the most risk-averse landowners and the least risk-averse tenants, while the least risk-averse landowners operate their own land. Our empirical results suggest that the rising use of cash rent contracts and declining incidence of owner-operation and crop-share rental contracts is consistent with falling coefficient of variation in expected net returns per acre.     

Off‐farm work,land tenancy contracts and investment in soil conservation measures in rural Pakistan

This study examines the impacts of participation in off‐farm work and land tenancy contracts on the intensity of investment in soil‐improving measures and farm productivity. A multivariate Tobit model that accounts for potential endogeneity between the intensity of investment and the off‐farm work and tenancy contract variables is estimated for 341 rural households in Punjab province of Pakistan. An instrumental variable approach is also used to analyse the impact of tenancy contract and off‐farm work on farm productivity. The empirical results show that participation in off‐farm work and tenure security tends to increase the intensity of investment in long‐term soil‐improving measures. We also find that increases in off‐farm work and tenure security exert significant and positive effects on farm productivity.     

Customary vs Private Property Rights? Dynamics and Trajectories of Vernacular Land Markets in Sub‐Saharan Africa

Contemporary discourse on land in Africa is polarized between advocates of tenure reform through state registration of individual titles to land and others who claim that customary or 'communal' tenure is the only check against landlessness among the poor in the African countryside, and that 'pro-poor' land policy should therefore strengthen customary rights to land. This paper draws on a growing body of evidence on the emergence of vernacular rural land sales and rental markets to question assumptions that underlie the non-market 'ideal type' communal tenure model that has historically dominated policy thinking in Africa, and continues to be shared by both sides of the current land tenure reform debate. The paper argues that recognition of the specific characteristics of 'vernacular land markets'– commoditized transfers of land within the framework of customary tenure – is essential if state land policies are to succeed in promoting the interests of the poor.     

Tenants, Landlords, and Soil Conservation

It has long been argued that tenants tend to overexploit land, but this conventional wisdom has been derived largely without consideration of landlords' actions. We examine what happens when landlords can invest in durable conservation measures in addition to choosing rental contract terms. When tenants are risk neutral, landlords overinvest in conservation under cash rental contracts but can achieve first best levels of output and protection against land degradation when conservation investment is combined with share rental. When tenants are risk averse, the first best is unattainable. In this case, conservation investment combined with share rental results in output levels below the first best, while equilibrium conservation investment may be greater or less than the first best. These results suggest that contract form and conservation investments are likely made simultaneously, so that econometric studies of conservation practice adoption that treat rental status as exogenous are likely subject to bias.     

Cattle sharing and rental contracts in an Agrarian economy: evidence from Ethiopia

Empirical evidence on the role of cattle sharing and rental contracts in agrarian economies is limited. This article is an investigation of different types of cattle sharing and rental contracts producers in rural Ethiopia adopt. It also investigates why households in rural Ethiopia rely on these contracts that are vulnerable and therefore subject to potential moral hazard problems described in earlier literature. We apply random effect probit and control function econometric methods to household panel data collected in 2005 and 2007 from two agro‐ecological zones in Ethiopia. Controlling for the endogeneity of access to livestock credit, we find that contracts are spatially fragmented and better developed where population density is high and credit and insurance markets are poorly developed. We also find that contracts help cash poor and credit constrained households to improve their herd dynamics, to get access to nonlivestock resources (land, labor and cash) and share risks that could have been difficult without the contract. We show that contracts are rational responses of residents in rural communities characterized by imperfect credit and insurance services, since households with better access to credit are less likely to rely on contracts.     

Variation in Output Shares and Endogenous Matching in Land Rental Contracts: Evidence from Ethiopia

We investigate the extent of variation in output sharing in land rental contracts and alternative hypotheses to explain this variation. Close to half of the rental contracts in our study in northern Ethiopia have output shares that deviate from the dominant 50–50 equal sharing. Variation in land quality, the relative bargaining power of landlords and tenants, production risks and shocks are hypothesised to influence output shares. Matched data of landlords and tenants are used. The importance of endogenous matching of landlords and tenants is investigated by assessing how endogenous tenant characteristics are correlated with landlord characteristics. We find evidence of negative assortative matching for key resource characteristics. A control function approach is used to control for endogenous matching in the output share models. The results reveal that production risks, as well as relative bargaining power, affect output shares in the reverse tenancy setting where tenants are relatively wealthier and more influential than landlords.     

Household Tree Planting in Tigrai,Northern Ethiopia: Tree Species,Purposes, and Tenure Security

Trees on farms have multiple roles in rural livelihoods, providing significant economic and ecological benefits. Trees on farms also constitute vital components in mixed crop-livestock-tree systems. In this paper, we analyze household tree planting and tenure security and explore the most important determinants that enhance the propensity to plant trees, using a cross-sectional household-level dataset from a sample of 200 households in the highlands of Tigrai, northern Ethiopia. Specifically, we employ a sample selection model that simultaneously takes into account the two decisions of tree growers (whether or not to plant tree and how many) to analyze the effect of tenure security on tree planting. We also use a multinomial logistic regression model to analyze the most important determinants contributing to a household’s decision of planting of particular tree species. We find that, among other things, tenure security enhances the propensity to plant trees as well as the amount of tree planting. Findings also suggest that households consider a diversity of attributes in making decisions to plant specific trees. These results can be used by policymakers to promote on-farm and homestead tree cultivation of private households in the study area by strengthening tenure security and considering households’ choices of specific tree species based on their attributes.     

Land tenure security for women: A conceptual framework

While strengthening women’s land rights is increasingly on national and international agendas, there is little consensus on how to understand women’s tenure security. Analyses of women’s land rights often use very different definitions of land rights, from formal ownership to women’s management of plots allocated to them by their husbands. This paper identifies aspects of women’s tenure that should be included in indicators. It then provides a conceptual framework to identify the various dimensions of women’s land tenure security and the myriad factors that may influence it. To be able to compare women’s tenure security in different places, we need information on the context, the threats and opportunities facing tenure security, and the action arena that includes both the people who play a role in promoting or limiting women’s tenure security and the resources used in doing so.     

Land tenure security and its implications for investments to urban agriculture in Soweto,South Africa

Land tenure regime is considered one of the most crucial assets determining viability of urban agriculture, especially in terms of investments. Many authors have built on traditional agricultural theory that only land ownership and (formal) secure land tenure can incite investments into farming, thus stressing the need of secure land tenure for more prosperous urban agriculture. However, these statements are often built on weak or nonexistent empirical evidence. This research aims to contribute to the discussion on land tenure for urban agriculture by mixed-method exploration of the above-mentioned theory. Additionally, we propose a farming investment index which measures the level of investments by using non-monetary information obtained from respondents. The results of our study show that land tenure security for urban farmers is often seen as a rather narrow concept, focusing only on legal tenure security but omitting its other dimensions such as perceived and de facto tenure security. Nevertheless, all three dimensions of tenure security positively influence investments to urban agriculture.
