“…Saka (2017) examined the association existing between people of working age and carbon emission in Africa with panel data spanning 1960–2012. Adopting static panel techniques and grouping African countries into low‐income, upper income and low‐middle income, the result revealed that active population has decreasing influence in both low‐ and upper‐income nations, while it has a rising effect on low‐middle nations.…”

This study aims to investigate the influence and the direct causal relationship between energy consumption and the selected explanatory variables in the Nigerian economic system. Using ARDL‐VECM over the period of 1972–2014, the results are that financial development exerts negative and significant influence on energy consumption. Trade openness and urbanisation exert positive and significant effect on energy consumption both in the short and long run, the active age (15–64) and old age (65 and >) have different effects on energy consumption. Although the number of the older population (age 65 and above) causes the energy consumption level to fall, the size of the working/active population (age 15–64) causes the energy consumption level to increase. Further results revealed (i) unidirectional causality runs from working population to energy consumption, (ii) uni‐directional causality runs from energy consumption to credit to private sector, (iii) uni‐directional from trade openness to real GDP per capita, (iv) bi‐directional causal relationship is observed between urbanisation and energy consumption, (v) bi‐directional relationship between trade openness and energy consumption. These findings may be a guide to policymakers in evaluating Nigerian economy's energy needs and effective energy policies needed to address environmental issues related to fossil fuel use.

“…Population growth and its impacts on environmental issues have been studied intensively [8,9]. However, in most cases, the population is considered as a single, onedimensional variable; population numbers, or population density, are used as a variable to explore the population-environment nexus.…”

Population is the main driver of land-system and environmental change. However, population is usually treated as a variable that only considers the population number, and multi-dimensional population structure is largely ignored. There has been a systematic transition of population structure in the past several decades, including changes in household structure, increasing aging populations, increasing divorce rates, and increasing human migration. All of these changes have direct or indirect impacts on land use and environmental issues. Here, taking China as an example and using statistical analysis, namely the Mann–Kendall trend test and a land-use-transition matrix, we examine the relationship between household dynamics and land-use change in China by examining changes in household structure and land-use changes in China between 1980 and 2020. The results show the following three groups of findings. (1) The number of households increased by 130.95% from 1980 to 2020, while the population only increased by 42.83%; the size of households decreased from 4.41 to 2.92 in China from 1982 to 2020; and the household dynamics varied from province to province, which is affected by urbanization rate and economic development. (2) Birth rates, divorce rates, population aging, and migration all affect household structure, which directly or indirectly affect changes in land-use systems. (3) The changes in China’s land use are interlinked and interact with changes in household structure, which is evident in the increase in Residential land use and the abandonment of arable land. The rising household number increased the area of urban and rural settlement, leading to the fragmentation of cultivated land and the reduction of ecological land. To regulate land-use change for sustainable development, future land-use planning should take into account the effect of household dynamics and should reduce the negative effects of household dynamics on land systems and environmental change.

Population is the main driver of land systems and environmental change. However, the population is usually treated as a variable that only considers the population number, and the multidimensional population structure is largely ignored. There has been a systematic transition of population structure in the past several decades, such as the changing household structure, the increasing aging population and divorce rate, and human migration. All these have direct or indirect impacts on land use and environmental issues. Here, we will take China as an example to examine the relationship between household dynamics and land use change in China by exam-ining changes in household structure and land use change in China between 1980 and 2020. The results show:1) the number of households increased by 130.95% from 1980 to 2020, while the population only increased by 42.83%. The size of households decreased from 4.41 to 2.92 in China from 1982 to 2020. The household dynamics vary from province to province, which is affected by urbanization rate and economic development. 2) Birth rates, divorce rates, population aging, and migration all affect household structure, which directly or indirectly affects changes in land use systems. 3) The changes in China's land use are interlinked and interact with changes in household structure, evident in the increase in residential land use and the abandonment of arable land. The rising household number increased the area of urban and rural settlement, leading to the fragmentation of cultivated land and the reduction of ecological land. To regulate land use change for sustainable development, future land use planning should take into effect of household dynamics, and reduce the negative effects of household dynamics on land systems and environmental change.
