The decoupling elasticity decomposition quantitative model of energy-related carbon emission in Guangdong is established based on the extended Kaya identity and Tapio decoupling model for the first time, to explore the decoupling relationship and its internal mechanism between energy-related carbon emission and economic growth in Guangdong. Main results are as follows. (1) Total production ener...

This paper considers the implications of population growth and urbanization for climate change. It emphasizes that it is not the growth in (urban or rural) populations that drives the growth in greenhouse gas (GHG) emissions but rather, the growth in consumers and in their levels of consumption. A signifi cant proportion of the world’s urban (and rural) populations have consumption levels that ...

the relationship between population structure and violent conflict is complex and heavily dependent on the behavior of other variables like governance, economic prospects, and urbanization. while addressing rapid population growth might be a necessary condition for peace, it is by no means sufficient. concomitant steps must also be taken to foster inclusivity, guarantee broader rights for all, ...

Foresight Studies analyze emerging issues and trends with the objective of quantifying the research challenge and the potential impact for agricultural research. The past century has entailed a relatively speaking rapid redistribution as well as growth of urban populations, with the urban population surpassing the rural one for the first time in 2008. Processes of urban growth and their implica...

Abstract Urbanization is treated in the literature as a process that occurs along with economic development. We consider an overlapping generations model two regions, designated ‘urban’ and ‘rural’. Concentration of population to urban areas involves inflows from rural areas, thereby exacerbating congestion. Inverse agglomeration economies exert negative effects on income, consequently increasi...
