How Do Non-Agricultural Employment and Regional Selection Affect Farmers’ Domestic Sewage Discharge Behavior? Empirical Evidence from Rural China

Abstract

In many countries, along with rising rural labor transfer, the problem of rural domestic sewage discharge is becoming increasingly serious due to labor shortages in the villages. It is urgent to solve the environment pollution and health problems of residents which is caused by the massive discharge of domestic sewage in rural areas. Based on the survey data collected from Nanjing Agricultural University in 2020, this paper employs the ordered probit model and the CMP method, to empirically test the impact of non-agricultural employment and regional choice on farmers’ domestic sewage discharge behavior and the moderating effect of environmental cognition and the social network. The results show that: (1) There is a significantly positive correlation between non-agricultural employment and farmers’ sewage treatment behavior. (2) Environmental cognition significantly improves the participation of urban non-agricultural employment farmers in sewage treatment, and the social network has a significant role in promoting the adoption of sewage treatment behavior of local non-agricultural employment farmers. (3) Further heterogeneity analysis results show that the inhibitory effect of urban non-agricultural employment on random sewage discharge is more pronounced than that of local non-agricultural employment. Therefore, in order to effectively solve the problem of rural domestic sewage discharge, it is necessary to actively guide the sewage discharge behavior of non-agricultural employment households, strengthen the social network interaction within the village, and increase the publicity for sewage discharge knowledge.

Does Construction of High-Standard Farmland Improve Recycle Behavior of Agricultural Film? Evidence from Sichuan, China

“…The higher the proportion of farm employment, the higher the willingness of farmers to adopt RBAF. Compared with studies on an off-farm labor force, this result is contrary to the conclusion of Issahaku et al [72], Gedikoglu and McCann [73], and Ju et al [74], that the higher the proportion of off-farm labor, the higher the possibility of adopting environmental protection behavior. This study speculates the following reason: In addition to mechanical factors, the RBAF needs to rely on more manpower for recycling.…”

Ferrite-Supported Nanocomposite Polymers for Emerging Organic and Inorganic Pollutants Removal from Wastewater: A Review

“…35 These contaminants mostly come from human and naturally occurring sources, such as sewage discharge that is not under control, among others. 36 They have been shown to affect the metabolic processes of many different systems, including those of flora, fauna, and humans. 37 Table 1 gives the toxicity level of various inorganic pollutants present in wastewater along with its impact on human health.…”

“…Inorganic pollutants are poisonous, nonbiodegradable substances that, even in tiny amounts, can have a negative impact on health . These contaminants mostly come from human and naturally occurring sources, such as sewage discharge that is not under control, among others . They have been shown to affect the metabolic processes of many different systems, including those of flora, fauna, and humans …”
