    Land titling policy and soil conservation in the uplands of Northern Vietnam
    (2008) Dung, Pham Thi My; Saint-Macary, Camille; Keil, Alwin; Zeller, Manfred; Heidhues, Franz
    In Vietnam, a quasi private property regime has been established in 1993 with the issuance of exchangeable and mortgageable long term land use right certificates. Using primary qualitative and quantitative data collected in a mountainous district of Northern Vietnam, this paper investigates the role of the land policy in the adoption of soil conservation technologies by farmers. This issue is of crucial importance in the region where population growth and growing market demands have induced farmers to intensify agricultural production. While poverty has been reduced, environmental problems such as soil erosion, landslides, and declining soil fertility have become more severe over the past years. Among the abundant literature on the impact of property rights and formal land titles in developing countries, only a few studies have focused on the adoption of soil conservation technologies: an important element in sustainable development strategies of fragile agro-ecological areas confronted with increasing population densities. Our findings suggest that soil conservation technologies are perceived as being economically unattractive; therefore, most upland farmers continue to practice the prevailing erosion-prone cultivation system. Focusing on agroforestry as one major soil conservation option, we estimate household and plot level econometric models to empirically assess the determinants of adoption. We find that the possession of a formal land title influences adoption, but that the threat of land re-allocations in villages discourages adoption by creating uncertainty and tenure insecurity. We conclude that more efforts are needed from decision-makers to promote and support the adoption of conservation practices and to clarify objectives of the land policy in order to secure land tenure and foster sustainable development in fragile areas.

    Landslides in mountainous regions of Northern Vietnam : causes, protection strategies and the assessment of economic losses
    (2008) Zeller, Manfred; Saint-Macary, Camille; Pham, Van Dinh; Nguyen, Minh Duc; Keil, Alwin; Heinke, Antonia; Frör, Oliver; Ahlheim, Michael
    Landslides are a severe problem during the rainy season in many mountainous regions in Asia where forests have been cut so that mountain slopes are destabilized. In this study we analyze the extent and causes of landslides in a mountainous area in Northern Vietnam as viewed from the perspective of the concerned population. We also scrutinize the ideas of these people regarding suitable landslide protection measures and their willingness to contribute to the practical implementation of these measures. It shows that nearly all people living in this area feel highly concerned about the frequent landslide events and that they support the idea of government programs to mitigate the danger of future landslides. We measure the utility they expect from such a landslide protection program, i. e. the social value of such a program, in terms of their willingness to contribute personally to its implementation. Since budgets are tight in these rural areas where subsistence farming still prevails we also analyze the possibilities to measure these expected utility gains in terms of people's willingness to contribute working time instead of money to the proposed landslide protection program. The prospect of employing such an alternative means of contribution is, however, seen rather critical.

    Maize boom in the uplands of Northern Vietnam : economic importance and environmental implications
    (2008) Zeller, Manfred; Saint-Macary, Camille; Keil, Alwin
    In Vietnam, the demand for meat products has grown dramatically due to rapid economic growth and urbanisation and is expected to further increase in the future. Being the primary source of feed for the country?s livestock and poultry industry, maize has become the second most important crop after rice. While this maize boom has the potential to reduce rural poverty, it promotes the expansion of agricultural cultivation into fragile agro-ecological zones, often leading to deforestation and soil degradation, especially in the uplands. Using empirical evidence from mountainous Yen Chau district in north-western Vietnam, the objective of this paper is to investigate the current economic importance and environmental implications of maize cultivation. Furthermore, particular emphasis is placed on the identification of factors influencing farmers? decision how much area to allocate to maize in order to derive research and policy recommendations. Maize is the dominant crop in Yen Chau, covering most of the uplands and generating the lion?s share of households? cash income. Although farmers are well aware of soil erosion on their maize plots, effective soil conservation measures are rarely practiced. Maize is attractive to farmers from all social strata, notably the poor, and through marketing arrangements with traders its cultivation is also not constrained by poor infrastructural conditions. Access to low-interest credit should be enhanced to mitigate farmers? risk of being caught in a poverty trap when maize revenues plummet due to pests, diseases, price fluctuations, or adverse weather conditions. To address the problem of soil degradation in the maize-dominated uplands, research is needed on soil conservation options that are economically more attractive than those promoted thus far.

    Microeconomic impacts of institutional transformation in Vietnam?s Northern uplands : empirical studies on social capital, land and credit institutions
    (2012) Saint-Macary, Camille; Zeller, Manfred
    Vietnam's economic achievement over the last two decades is frequently regarded as a successful case of development. The Doi Moi reform program enacted in 1986 gradually led the transition from a centrally-planned to a market-oriented economy. In rural areas, reforms entailed a deep transformation of institutions and were aimed at placing back farmers at the center of decision making as a way to boost agricultural production and alleviate poverty. Agricultural markets were gradually liberalized, user rights were transferred to smallholder farmers for most of the agricultural land, and anti-poverty programs were implemented. At the national level, the high economic growths in all sectors of the economy have permitted a drastic reduction of poverty. These successes however did not take place evenly through the country. Mountainous regions and its inhabitants have lagged behind in the process. The poverty incidence in the Northern Uplands was still twice as large in 2008 than in the rest of the country. In addition, the rapid population growth combined with the intensification and expansion of agricultural systems into fragile ecosystems have considerably increased pressure on natural resources. This accentuates the risk for resource-based economies such as Vietnam?s mountainous regions to get trapped in a vicious circle whereby environmental degradation and poverty mutually reinforce each other and durably undermine economic development. The existence of complex relations between poverty and environmental degradation in fragile ecosystems implies that equity, economic growth and environmental sustainability cannot be treated as separate objectives but must jointly be addressed to ensure sustainable development. Drawing on a conceptual framework that highlights the determinant role of institutions in the poverty-environment nexus, this thesis investigates to which extent the current institutional framework addresses objectives of equity, economic growth and environmental sustainability. It focuses on three critical dimensions: the definition of property rights, the functioning of intertemporal markets, and social capital. More specifically, the thesis addresses the following research questions: (i) Has the individualization of land access and land titling policy enhanced tenure security, and thereby increased the adoption of soil conservation practices? (ii) Has a land market emerged in the study area? (iii) Is the credit market equitable and efficient? Does state intervention induce a more equitable and efficient allocation than other sectors? (iv) Does ethnic diversity undermine collective action and the formation of social networks? These questions are investigated empirically in the six chapters of this thesis. Analyses build on a rich and primary quantitative household- and village-level dataset collected in 2007/2008 in Yen Chau, a mountainous district of the Northern Upland region, as well as on qualitative information gathered in the field through focus group discussions and informal discussions with local stakeholders. Successes of the land reform lie in its egalitarian character which enables most farmers to cultivate land with long term user rights. Yet, results show that tenure security is not fully guaranteed and land reallocations conducted by the government as well as its indecision regarding the prolongation of land use rights at the end of their term have created mistrust and uncertainty. The incertitude is found to impede the adoption of soil conservation technologies and to hamper the land market, depriving the local economy from potentially important equity and efficiency gains, and threatening environmental sustainability. The credit market, thanks to good levels of social capital, is found to function relatively well and enable all farmers including the poor to finance agricultural input and consumption through loans. The state-governed formal sector, despite offering competitive contract terms remains a secondary credit source, particularly for the poor. The costly micro-credit program of the government fails to reach the poor and is found to have only limited impact on welfare. This inefficiency causes an important leakage of state resources. Finally, we do not find as predicted by the literature, that ethnic heterogeneity undermines participation in local organizations and the formation of social networks. This impact appears to depend on the political nature of organizations, and the public nature of goods managed. Moreover, evidence shows that heterogeneity encourages bridging connections among farmers and constitutes as such a factor that can foster innovations and economic development. The contributions of this thesis are twofold. First, it identifies sources of success and failure in the current institutional framework to promote sustainable development in Vietnam?s mountainous areas from which we derive policy recommendations. Evidence in this thesis highlights limitations of the top-down approach that dominates public intervention in mountainous areas. These interventions are usually costly and not always successful in enhancing equity, efficiency and the environmental sustainability of resource use. This stresses the need for the Vietnamese government to further enhance the functioning of incentive-based mechanisms in the economy as a complement to current policies. In this perspective, the clarification of the land reform objectives, the development of a land market, the promotion of independent and financially sustainable financial institutions, the reinforcement of the legal system, and the support of the emergence of an independent civil society are all measures that may support sustainable development in Vietnam?s mountainous regions.
