“…In this way, our findings of the presence of an EKC for nitrogen surplus are not as straightforward as suggested by the literature (e.g., Li et al 2016, Paudel and Poudel 2013, Singh and Narayanan 2015, Zhang et al 2015. The results also show that even though there seems to be a clear presence of an EKC at first sight, it is necessary to conduct first difference estimation to control for omitted variable bias, which has led to opposite results in our analysis.…”

We examine the relationship between nitrogen surplus per hectare and the median monthly wage per capita considering the Environmental Kuznets Curve (EKC) theory. The EKC hypothesizes an inverse U-shape relationship between environmental pollution and per capita income. We use a novel panel data set for nitrogen surplus as an environmental pollutant and a measure of the median monthly wage per capita during the period from 1999 to 2018 for 401 counties in Germany. Our estimation results show that nitrogen surplus displays a spurious EKC in Germany. It is spurious because the inverse U-shape relationship of nitrogen surplus and median wage is rejected by almost all model specifications and by tracing of individual county paths. This implies that in Germany economic growth has not cleaned up the environmental damage from nitrogen surplus. The affected counties remain in a spatial cluster (shown with the individual county paths) that they cannot break out of in the course of the EKC, at least not without political intervention.

“…Our analysis suggests that many countries show a pattern similar to an Environmental Kuznets Curve (EKC), in which N 5 pollution first increases and then decreases with economic growth [18][19][20][21] . So far, most EKC analyses have focused on pollution from industrial and transportation sectors 19,22,23 ; the present study is one of few to consider agricultural N pollution in the EKC context 24,25 , and to apply it globally. However, the patterns of N pollution are neither automatic nor inevitable.…”

Improvements in nitrogen use efficiency in crop production are critical for addressing the triple challenges of food security, environmental degradation and climate change. Such improvements are conditional not only on technological innovation, but also on socio-economic factors that are at present poorly understood. Here we examine historical patterns of agricultural nitrogen-use efficiency and find a broad range of national approaches to agricultural development and related pollution. We analyse examples of nitrogen use and propose targets, by geographic region and crop type, to meet the 2050 global food demand projected by the Food and Agriculture Organization while also meeting the Sustainable Development Goals pertaining to agriculture recently adopted by the United Nations General Assembly. Furthermore, we discuss socio-economic policies and technological innovations that may help achieve them.

“…It shows that increasing the ratio of capital to fertiliser can not only increase the green bias towards technological progress, but also suppress the pollution bias towards technological progress. This is because perfect irrigation facilities can dilute fertilisers and help crops absorb nutrients (Singh & Narayanan, 2015). At the same time, the use of large machinery can return crop waste to the field, which is a green technological advancement.…”
