The purpose of this paper is to examine the impact of farmers’ risk perceptions regarding rubber farming on their land use choices, including rubber specialization and crop diversification.

A cross-sectional survey data of some 600 smallholder rubber farmers in Xishuangbanna in Southwest China is employed. This paper develops a general conceptual framework that incorporates a subjective risk item into a model of farmers’ land use choices, thereby developing four econometric models to estimate the role of risk perceptions, and applies instrumental variables to control for the endogeneity of risk perceptions.

The results demonstrate that risk perceptions play an important role in smallholders’ decision-making regarding land use strategies to address potential risks in rubber farming. Smallholders with higher risk perceptions specialize in rubber farming less often and are more likely to diversify their land use, thereby contributing to local environmental conservation in terms of agrobiodiversity. The land use choices of smallholder rubber farmers are also associated with ethnicity, household wealth, off-farm employment, land tenure status, altitude and rubber farming experience.

This study contributes to a better understanding of the implications of farmers’ risk perceptions and shows entry points for improving the sustainability of rubber-based land use systems.

The purpose of this paper is to examine the status of the supply reliability of groundwater irrigation, and discuss how it is affected by climate change and tubewell density in rural China.

This study is based on a nine-province village survey and secondary climate data. A Tobit model (or censored regression model) was used to estimate the determinants of supply reliability of groundwater irrigation.

Results show that the supply reliability of groundwater irrigation was 89 percent on average in the past three years. The non-linear relationship in the econometric results revealed that the 30-year annual temperature significantly influenced the supply reliability of groundwater irrigation. When the temperature rises above the turning point (6.30°C), it shifts from a positive to a negative relationship with the supply reliability of groundwater irrigation. The 30-year annual temperature in eight of the nine provinces (i.e. except for Jilin Province) was higher than the turning point. If the temperature increases by 20°C in the future, other factors being constant, the supply reliability of groundwater irrigation will decline by 20 percent. However, if precipitation increases by 10 percent, the supply reliability of groundwater irrigation could improve by 3 percent, while reducing precipitation by 10 percent will lower the supply reliability of groundwater irrigation by 3 percent. Increasing the density of tubewells considerably improves the supply reliability of groundwater irrigation. However, although increasing the density of tubewells may yield enough groundwater for irrigation, this one-sided approach raises sustainability concerns.

Although increasing the density of tubewells may ensure that enough groundwater is available for irrigation, such a conclusion is one sided, and sustainability concerns should be raised in assessing this method of creating supply reliability.

This paper improves the understanding of the impact of climate variables on agriculture irrigation and water supply reliability in the micro scale, and provides a scientific basis for relevant policy making.

There is growing interest from the global development community in the role of agricultural research and extension (AR & E) systems to achieve development targets. Despite this interest, many smallholders in developing countries continue to lack access to updated agricultural information and reliable services. In an effort to increase the effectiveness, impact, and reach of AR & E programs, many governments have attempted to reform their national systems. The paper aims to discuss these issues.

This paper systematically compares the systems and reforms of AR & E in China and India in order to draw out lessons applicable to developing countries. This paper first reviews the existing literature on AR & E systems and their role in agricultural and economic development. The authors then provide a detailed review and comparative analysis of the reforms and approaches implemented in the AR & E systems of China and India. The authors apply this comparative analysis to draw out lessons that can be applied to inform the reformation of AR & E systems in developing countries.

The authors find that although both countries face similar agricultural development challenges, each took a different approach in the reformation of AR & E to address these challenges. Each country’s approaches had different impacts on the effectiveness of the system. Lessons from the reformation of the AR & E systems in China and India can be used to inform and improve the impact of AR & E in developing countries.

The paper examines two systems together using a set of common indicators and factors. The paper’s value comes from its usefulness in informing future AR & E reforms in other developing countries in order to increase the impact of these reforms on development outcomes.

The purpose of this paper is to analyze the different types of domestic waste disposal in rural China and the major factors that affect rural household waste disposal behavior.

Stratified and randomly sampled household data are used to describe the disposal of domestic waste in rural China, including domestic garbage and organic waste (human excreta, livestock waste, and kitchen waste); econometric models are estimated to quantify the major determinants of household domestic garbage and human excreta disposal.

While about 30 percent of the domestic garbage in 2008 was discharged to appropriately designated places, more than 40 percent of the garbage was discharged casually. Organic waste at the time of data gathering was still largely used in agricultural production, although a falling trend has been evidenced in recent years. Based on econometric analysis, it becomes clear that income growth, rising population density, and transportation improvements have significantly improved domestic garbage disposal, but negatively affected the recycling of human excreta. The provision of an adequate garbage collection service has the most positive effects on garbage management.

The analyses are based on primary survey data. The results will have significant policy implications on the management of rural domestic waste to maintain better rural environment.

Since the 1980s agricultural biotech investments by the public sector have increased substantially in both China and India. In the last two decades there has also been a dramatic increase in private section investment in agricultural biotechnology particularly in India. The promise of major benefits of Bt cotton identified in early socioeconomic studies of Bt cotton has proven to be true. Bt cotton has spread to at least 66% and 85% of total cotton areas of China and India, respectively – wherever bollworm is a major problem. Bt cotton continues to control bollworm in both countries, and farmers continue as major beneficiaries rather than biotech or seed companies. The major impacts have been yield increases in India and reduced pesticides consumption in China. In China, evidence also suggests that Bt cotton has suppressed the bollworm population so that non-Bt cotton growers and producers of other crops that are susceptible to bollworm are also benefitting.

The chapter also provides evidence that in the near future Bt rice and Bt eggplant could have major positive impacts by reducing pesticide use and farmers’ exposure to chemical pesticides and increasing yields. Both crops were approved for commercial production by government biosafety regulators, but are not yet available for commercial cultivation.

The purpose of this study is trying to document and examine the impacts of pesticide use on farmers' health. Different from previous studies, the paper is not only going to focus on the visible effect, but also the invisible effect. At the same time, the paper is going to divided the pesticides into highly toxic and low toxic pesticides and estimate their different impacts on farmers' health, respectively.

This paper uses regression techniques based on a farm household survey gathered by the authors in Zhejiang provinces. In addition to a sit‐down interview with 100 households, the authors gave a comprehensive physical examination and a blood examination to farmers who applied pesticides most frequently in each household.

This paper indicates that farmers who spray more pesticides are more likely to have headache, nausea and skin problems. Beside these visible effects, this paper also finds that exposure to pesticides has significant invisible impact on farmers' neurological, liver and kidney systems.

This, it is believed, is one of the first comprehensive studies to give comprehensive physical examination and blood examination to farmers who applied pesticides most frequently in each household.

Internationally, microfinance run by non-governmental organizations (NGOs) is often considered an important approach to meeting the credit demand of rural households, particularly among the poor. However, the perceived competitions with formal financial institutions and concerns about financial risks in the rural economy have impeded the development of microfinance by NGOs in China. Despite these concerns about NGO microfinance, little empirical evidence has been brought to prove them. The purpose of this paper is to provide empirical evidence of the relationship between NGO microfinance and farmers’ demand for formal and informal credit in rural China.

The study is based on a household longitudinal data set consisting of 749 households from 40 microfinance villages in rural China. This study draws evidence from China's largest NGO microfinance. Out of the five county branches where China Foundation for Poverty Alleviation has launched institutionalized microfinance since 2006, the authors selected two of them. A random sampling approach was applied in surveying villages and households. In an effort to create impact assessments, the authors surveyed the detailed information on household characteristics and credit access during the period 2006-2009. A panel data is thus structured for the analysis.

The authors found that the demand for credit in rural China is immense and rising, as formal financial institutions have gradually moved away from less developed regions in rural areas. In its place, informal lending has become a primary source of credit for the poor. However, where NGO microfinance has become available, both formal and informal credit has slowed down. The development and expansion of NGO microfinance did stand up as a substitution for institutional lenders and informal financial networks.

The findings have profound policy implications. First, since the development of NGO microfinance fill the demand for credit in rural China and poses low financial risk, the intellectual bias against NGO microfinance is unwarranted. In particular, the regulations that hamper the development of NGO microfinance should be corrected. Second, informal networks do not appear to be costless. Where NGO microfinance can substitute for them, it can mitigate the financial stresses related to the informal credit market.

Developing nations need good cultivated land rental markets to foster rational resource use and to enhance productivity and equity. Can cultivated land rental markets emerge in the face of rapidly developing off‐farm labor markets? The purpose of this paper is to measure the correlation between the emergence of off‐farm employment and cultivated land rental in China.

Based on a panel data from 2000 and 2008, the authors constructed econometric models to identify the impact of off‐farm employment on the decisions of households to rent out and rent in cultivated land.

This paper finds that the emergence of off‐farm employment has significant and positive impacts on stimulating household to rent out cultivated land. The effect is less prominent for renting‐in decisions.

The paper empirically estimates the impacts of off‐farm employment on cultivated land rent markets based on a unique panel data set from a national representative sample.

This paper aims to explain why the quality of infrastructure projects in rural China differs from village to village and how project quality is correlated with project design attributes and governance factors.

Using primary data collected by the authors on three types of infrastructure projects in villages across China, they created measures of project quality for each village. They then used both descriptive and multivariate approaches to examine how quality varies from village to village and factors correlated with quality.

Between‐project within‐village quality differences are small and project design has little explanatory power. Between‐village variations are large. There are strong correlations between the ways villages govern themselves and project quality. The authors conclude that it is difficult to make good projects work in communities that lack good governance.

Disaggregated data on the quality of infrastructure (and its determinants) were collected by the authors to allow for variation in the type of infrastructure projects (roads, irrigation, and drinking water) and variation in village governance, making it possible to identify and contrast the effects of project design and village governance factors on project quality. As its chief contribution, this work identifies potential ways to improve the quality of infrastructure projects in rural development.

The purpose of this paper is to empirically examine how China's food safety standards affect agricultural trade in the case of dairy products.

A gravity model is applied to quantitatively address the impacts of changing food safety standards in China in the case of its dairy imports. The paper considers the trade impacts of not only a specific hazard substance but also overall strictness of safety standards.

The paper shows that changes in food safety standards of dairy products have no effect on China's dairy imports. The finding is not particularly surprising considering special characteristics of China's food safety standards. Given the fact that China's safety standards are relatively lower than that in its major exporters, the trade-impeding effect may not be substantial.

First, this study is unable to estimate the trade-enhancing and trade-impending effects separately. Second, the study does not account for a potential endogeneity issue associated with food safety standards.

This paper contributes to the debate on how food safety standards affect trade by demonstrating that safety standards in developing countries like China can affect international trade differently from that in developed countries. Although results are specific to China's dairy imports, the explanations are applicable to food safety standards in other developing countries.
