Over-fertilization has caused serious environmental problems and high agricultural production costs at the household level in China. This study attempts to analyze the effects of grape growers’ fertilization knowledge and technologies on their over-fertilization behavior. Using survey data collected from 235 grape growers planting a particular grape (the “Hutai No. 8” grape) in Shaanxi, the marginal productivity of the chemical fertilizer (CF) as well as the effect of fertilizing knowledge and technologies on households’ over-fertilization behavior were examined, using the loss control production function and examining a two-part model, respectively. The results show that the average marginal productivity of the CF is 0.46 and that more than 75% of the participants were overusing CFs, with the probability and intensity of over-fertilization being lower when households have richer knowledge on how to determine the accurate fertilization time and match fertilizers with nutrient needs. The identification of nutrient deficiency symptoms has no significant effect on the over-fertilization behavior of households. In addition, the adoption of water and fertilizer integration technology (WFIT) can reduce both the probability and intensity of over-fertilization, while the adoption of the soil testing and formulated fertilization technique (STFFT) helps to reduce only the intensity of over-fertilization by households, but does not have a significant impact on the probability of over-fertilization. Therefore, policies aimed at reducing over-fertilization may focus on increasing households’ fertilization knowledge and adopting advanced technologies on fertilizer management.

To investigate the effect of improved property rights and, in particular, village democracy under China’s Collective Forest Tenure Reform (Tenure Reform) on household forestry investments, we estimate both tobit models and the more general Cragg models for farmers’ labor and monetary inputs into forestry, using survey data of 652 households from the southern collective forest region of China. The results reveal that the improved forestland use and disposition rights had a significant effect on household investments in forestry, while the beneficiary right did not. In addition, the results suggest that village democracy had a positive effect on households’ forestry investments. More importantly, we find that village democracy was able to significantly strengthen the investment incentive effect of the improved property rights under the Tenure Reform. These effects may be explained by the fact that village democracy improved households’ perception, cognition, and, subsequently, confidence toward, in particular, the use and disposition rights of the forests entitled to them. Therefore, the findings suggest that to increase the investment incentives of the Tenure Reform further, governments could strengthen the bundle of households’ use and disposition rights, as well as their related policies. Also, our findings indicate that governments could significantly improve the performance of public policies by effectively employing democratic procedures in the process of policy implementation.

Abstract:The implementation of China's natural forest protection project (Protection Project) in 1998 changed households' forestry production modes in project regions, and China's new circular collective forest tenure reform (Tenure Reform) has been implemented since 2003 with the goal of motivating household forestry production and increasing household income from forests. Policymakers expect that Tenure Reform could also stimulate households to engage in non-timber forest products (NTFPs) production in Protection Project regions. However, only a few studies have investigated the effect of Tenure Reform on household NTFP production in Protection Project regions. To fill this gap, we built an integrative conceptual framework and estimated a corresponding structural equation model (SEM) using survey data from 932 households in Protection Project regions in southwestern China. In our research framework, there are four factors, including household characteristics, labour and social capital, forestland characteristics, and the Tenure Reform, affecting household NTFP production. The results substantiate that Tenure Reform has had a significant positive effect on household NTFP production. Additionally, household and forestland characteristics have promoted household NTFP production, but quantitatively less than Tenure Reform. This report can be used to inform the government that future investment in Tenure Reform still needs to be enhanced, and policy enforcement still needs to be strengthened.

With increases in the frequency of various natural and social risks, effectively coping with uncertainty is necessary for the sustainable development of individuals and the society, particularly smallholder farmers with vulnerable livelihoods. Using survey data from farmers in China, we constructed a risk management capability index system for farmers at the individual, collective, and government levels to empirically analyze the impact of risk management on green production behavior through the Heckman model for two-stage sample selection. The results showed that risk management is a key factor affecting green production behavior. Membership status (membership in an organization), government subsidies, and income levels significantly promote green production levels. Moreover, risk management not only directly affects the green production level but also promotes green production behavior by expanding the scale of operation, improving the sense of responsibility, and enhancing the behavioral responsibility. Additionally, the mediating effect of these factors on farmers in the low-risk perception group was more obvious. Therefore, the risk management level of farmers should be improved at the individual, collective, and government levels to promote sustainable agriculture.
