Socio-economic drivers of agricultural production in a transition economy: A case study of Hu Village, Sichuan Province, China

Contemporary global agriculture has been undergoing transition towards different pathways. In developed countries, a shift from productivist agriculture to multifunctional agriculture has begun since the 1980s (Wilson, 2007). In the developing world, agricultural modernisation is still the primary strategy for agricultural development, and driven by urbanisation and industrialisation, deagrarianisation of rural society has been widely identified (Bryceson, 1996; Rigg, 2006a). As the largest developing country in the world, China embarked on market reform three decades ago and has ever since experienced dramatic socio-economic transition towards modernisation, industrialisation and urbanisation. Significant levels of academic attention have focused on empirically identifying economic and policy drivers of Chinese agricultural production from a structuralist standpoint, largely neglecting the agency of smallholders and sociocultural factors. To address the resulting literature gap, this thesis adopts an approach that combines political economy and cultural analysis through an in-depth case study of a rural community in southwest China. A multi-methods approach is used to collect data, including questionnaires, in-depth interviews, focus groups, participant observation and the analysis of secondary data. The results suggest that Chinese smallholder agriculture has been dramatically transformed by an array of socio-economic forces. The “intensive, sustainable, diverse” Chinese smallholder agriculture which Netting (1993) portrayed, has been progressively shifted towards extensive, unsustainable and less diverse pathways. It suggests that the “perfunctory agriculture” performed by Chinese smallholders is the outcome of interactions and negotiations between various political, socio-economic and institutional constraints and farmers’ agency. Another key finding is that moving out of agriculture is becoming the norm in Chinese rural society. Most smallholders show willingness to rent out agricultural land and to enter into a capitalist relationship with employees, rather than primarily being cultivators of their land. Land transfer markets have become increasingly buoyant at the local level, and large-scale capitalist agriculture seems to be the desired future of Chinese smallholder agriculture for both the Chinese government and smallholders. Besides, based on the case of Hu Village, this thesis discusses the convergences and divergences between the road of Chinese agricultural development and that of developed countries and other emerging BRIC economies. Lastly, based on the findings of this research, four policy implications are proposed including sponsoring agricultural mutual aid groups, strengthening agricultural extension services, enhancing farmers’ negotiation power through laws, and initiating comprehensive socio-economic reforms to facilitate farmers’ pursuit of non-farm employments

Optimal Analysis of Tunnel Construction Methods through Cross Passage from Subway Shaft

The conversion section of the cross passage and shaft is a priority concern in the stress transformation of a tunnel structure during subway underground excavation. In the construction of Subway Line 5 in Xi'an, China, the main line in the loess layer was constructed through the cross passage from the subway shaft of the Yue Deng Pavilion–San Dian Village Station tunnel section. Numerical simulation and field measurement were adopted to study the construction stability of the cross passage and shaft under two possible construction methods: the “shaft followed by cross passage construction” method and the “cross passage parallel shaft construction” method. The results showed that the surface deformation and plastic zone of the surrounding rock are similar under the two construction methods. However, of the two, the “cross passage parallel shaft construction” method was more advantageous in controlling the structural deformation of the original shaft and the stress distribution of the horsehead structure. The field monitoring data showed that the surface settlements and the deformation of the original shaft structures meet the requirement of control standards under the “cross passage parallel shaft construction” method

What Socio-Economic and Political Factors Lead to Global Pesticide Dependence? A Critical Review from a Social Science Perspective

Dependence on chemical pesticides has become one of the most pressing challenges to global environmental sustainability and public health. Considerable regulatory efforts have been taken to mitigate pesticide dependence, which however has resulted in a prevalent ‘managerial failure’. Massive pesticide application has generated severe genetic resistance from pests, which has in turn further aggravated pesticide dependence and thus induced agrochemical industries to develop new pesticide varieties. This review proposes to look beyond the resistance-dependence nexus and presents a comprehensive discussion about global pesticide dependence in a social science perspective, i.e., revealing the socio-economic and political factors that reinforce pesticide dependence. These factors are classified into five intertwined themes: (1) agricultural regime, (2) social process of pesticide application, (3) economic analysis, (4) politics and governance, and (5) promotional failure of alternatives. It is found that pesticide dependence is not just a technological issue in the sphere of natural sciences, but more a human-made issue, with deep-seated socio-economic and political reasons. Addressing contemporary trap of global pesticide dependence entails a full acknowledgement and comprehension of the complex and intertwined factors. Furthermore, this review identifies two major explanatory approaches underlying the extant social science literature: a structuralist approach that stresses macro-level structures such as institutions, policies and paradigms, and an individualist approach that focuses on the decision-making of farmers at the micro level. This review recognizes the limitations of the two approaches and calls for transcending the duality. This study advocates a policy framework that emphasizes alignment and coordination from multi-dimensions, multi-actors and multi-scales. For future research, collaborations between natural and social scientists, and more integrated and interdisciplinary approaches should be strengthened

Beyond a bottle of liquid: pesticide dependence in transitional rural China

Pesticide dependence is a major threat to food safety and local environment. Although numerous studies have explored different causes of pesticide dependence, few have examined how pesticides are locked into agricultural modernisation and rural transformation. Based on a case study of a Chinese village, this paper demonstrates how agricultural modernisation trajectory and rural changes have perpetuated the use of pesticides as necessities in agriculture as well as for farmers' livelihoods. Modern technologies, such as hybrid rice, conservation tillage, changes in crop structure, and reduction of intercropping all contribute highly towards pesticide dependence. The household responsibility system in China has provided the institutional foundation for increased pesticide use. Rural transformations driven by livelihoods diversification have created conducive social spaces for pesticide application. To step out of pesticide dependence, promotion of genetic diversity in agriculture, a reassessment of locational suitability of conservation tillage, institutional strengthening and the promotion of integrated pest management methods are suggested

Economic drivers of contemporary smallholder agriculture in a transitional economy: A case study of Hu Village from southwest China

Based on an in-depth case study of a rural community, this paper documents the contemporary state of Chinese smallholder agriculture and the changes that it has been experiencing in the context of dramatic socio-economic transition through the lens of three main economic drivers: livelihood diversification, market conditions and government interventions. Results reveal that the change in Chinese smallholder agriculture has been complex and multidimensional. All three factors exert profound influence and shape the current state of Chinese agriculture. Massive rural-urban migration has resulted in labour shortages, which in turn have led to a reduction in agricultural diversity and land use intensity and a shift from traditional labour-intensive technologies to modern capital-intensive technologies. However, because of well-developed agricultural markets, input use levels are similar across farmer categories (such as income diversification), helping to maintain productivity. Furthermore, reduced profits from farming due to increasing input prices and decreasing output prices have exerted pressure on smallholders to increasingly turn to nonfarm activities and have also triggered a thriving informal land transfer market, which was previously non-existent. Policy implications include the need to strengthen local economies, improve market conditions, invest in rural infrastructures and facilitate smallholders’ mobility

The resilience of diversified clusters: Reconfiguring commodity networks in rural China during the COVID-19 pandemic

We conceptualize typical rural communities in China as diversified economic clusters. In normal times, economic actors in these communities rarely cooperate with each other, but are integrated into separate commodity chains. These “diversified clusters”, however, show resilience and flexibility when an external shock—the COVID-19 pandemic—disrupts the spatial connections throughout the existing commodity chains. In this study, we use primary field data collected from one typical rural community in Northern China to show how economic diversity, aided by social networks and space-shrinking technologies, allowed for the vertical commodity chains to be reconfigured temporarily into localized horizontal commodity networks to cope with the emergencies brought about by the pandemic. Our findings suggest that while market integration can create precarity at the individual level, it can also contribute to economic resilience at the community level if it increases economic diversity and complementarity within the community. This study sheds lights on discussions of the resilience of rural and economic clustering by a novel conceptualization of diversified clusters and also offers a nuanced understanding of the connection between market integration and community resilience

Three-Dimensional Finite-Element Modeling for Asphalt Concrete Using Visual Cross-Sectional Imaging and Indirect Element Meshing Based on Discrete-Element Models

Numerical simulation for asphalt concrete using the finite-element (FE) method has been widely explored during the last few decades. However, the FE model reconstructions for asphalt concrete samples are mainly limited to the X-ray imaging approach. Although some computer-generated FE models have been used in previous studies, related work is still at a very preliminary stage. Different from FE modeling for asphalt concrete, discrete element (DE) modeling has been well developed using user defined aggregate models with the aid of commercial software. This study aims to bridge the DE models with FE models for asphalt concrete by using virtual cross-sectional imaging and indirect cubic element meshing. In the first approach, virtual cross-sectional imaging is conducted to identify the areas occupied by aggregate particles and air voids. These virtual cross-sectional images are afterward stacked to form three-dimensional (3D) solid models. Then, the 3D solid models are triangularly meshed and imported into the FE simulation software, ABAQUS. By this means, an FE model with tetrahedral elements is reconstructed. In the second approach, arranged spheres are generated to fill the entire sample first. The circumscribed cubes of the spheres are found and regarded as the cubic elements in FE models. An input file containing elemental and nodal information is directly written by PFC3D using user-written functions. Then the input file is imported into ABAQUS, and an FE model with hexahedral elements is reconstructed. This study provides a new and effective approach for FE model reconstruction of asphalt concrete with user defined aggregate and air void models. Additionally, the advantages and limitations of the two approaches are discussed
