What explains the intention to bring mobile phones for recycling? A study on university students in China and Germany

The analysis investigates the determinants of the intention to bring mobile phones for recycling. The paper is based on data regarding the determinants of bringing mobile phones for recycling collected from university students in Autumn 2016 (N = 1013) in both the Chinese and German academia. Using structural equation modeling, we examine the direct and indirect effects of social norms, knowledge about the environmental benefits of recycling and a pro-environmental attitude on the intention to recycle mobile phones. We find confirmation that attitude, social norms, and knowledge contribute positively and significantly to the intention to bring phones for recycling. As for three mediating effects tested, attitude mediates the relationship between knowledge and intention, as well as between social norms and intention. Knowledge as a mediator between social norms and attitude does not have a highly significant effect. Looking at the results of the Chinese and German sub-samples, we find that social norms have no direct effect on intention for the German sub-sample, but an indirect one through attitude. Knowledge has no significant effect for the German sub-sample. Results for the Chinese sub-sample indicate an indirect effect of social norms on attitude via knowledge, while knowledge itself has an indirect effect on intention through attitude.

Growth Enhancement Support Scheme (GESS) and Farmers’ Fertilizer Use in Rural Nigeria

Fertilizer use in Nigeria is estimated at 13 kg/ha, which is far below the 200 kg/ha recommended by the Food and Agricultural Organization (FAO). The objective of this investigation was to identify the determinant factors of farmers’ participation in Nigeria's Growth Enhancement Support Scheme (GESS). In addition, we determined the impact of the GESS on fertilizer use in rural areas. A total of 1,200 rural farmers were sampled across the six geopolitical zones of Nigeria. Results from the use of a recursive bivariate probit model indicated that GESS significantly impacted on the access and usage of fertilizer among the rural farmers; and that contact with extension agents, ownership of mobile phones, power for charging phone batteries, value output, mobile network coverage, ability to read and write were positive determinants of rural farmers’ participation in the GESS; whereas increased distance to registration and collection centers, and cultural constraints to married women reduced farmers’ tendency to participate in the GESS. The findings suggest that farmers’ participation in the GESS is a critical factor for raising fertilizer use in Nigeria. This implies that food security in sub‐Saharan Africa can be achieved by increasing the participation of rural farmers in the GESS.

Solar (photovoltaic) systems,energy use and business activities in Maphephethe,KwaZulu‐Natal

Literature suggests that energy is both a prerequisite for and essential to development (both social and economic). In order to establish the ability of an alternative energy source —photovoltaic systems ‐ to meet daily requirements, an investigation into current energy usage, expenditure patterns and business applications was conducted. Maphephethe, an area north of Durban in KwaZulu‐Natal, was selected for a formal survey, with locally based, trained interviewers interviewing 200 households and businesses. The findings indicated that income levels were slightly above national (rural) norms but displayed a wide variability. Eleven energy sources were used, including candles for illumination, car batteries for television sets, dry batteries for radios and wood for cooking. Paraffin and gas were used for refrigeration. The general attitude towards solar home systems was favourable but the interviewees perceived grid electricity as being better. There did not appear to be any difference between those households that had solar home systems and those that did not. Expenditure saved on traditional energy sources matched that spent on solar syst‐ems. Business energy‐related potential was present but not developed
