“…UrbWage, is the urban wage as specified by the ratio of the value of gross industrial output over the nonagricultural population for a county in a given year (1989, 1995 or 2000). High urban wages are expected to increase the opportunity costs of farming, and result in labor scarcity in the agricultural sector (Conelly, 1994). AgriInvest represents the agricultural investments per capita in a county for a given year (1989, 1995 or 2000).…”

“…UrbWage is average urban wages of staff and workers for a county in a given year (1995, 2000, 2005, or 2008). High urban wages, which indicate greater off-farm opportunities, are expected to increase the opportunity costs of farming, and result in labor scarcity in the agricultural sector [42]. We use these two variables to examine the relationship between urbanization and fertilizer use intensity.…”

China's urbanization has resulted in significant changes in agricultural land use. However, understanding of the linkages between urbanization and fertilizer use intensity is limited. Using county-level panel data for Henan Province, 1995Province, -2008 and panel econometric models, we investigate the impact of urbanization and other socioeconomic factors on fertilizer use intensity, with a focus on the two key processes related to urbanization-shrinking agricultural land area and increasing urban wages. Our results show that declining agricultural land per capita is associated with greater fertilizer use intensity. Urban wages is positively correlated with fertilizer use intensity. We also find that GDP per capita and per capita expenditure of government for agriculture both positively contribute to the increase of fertilizer use intensity, which is consistent with expectations. Our results imply that other than land conversion, urbanization contains some positive influences on land use sustainability. However, on the other hand, urbanization contributes to agriculture-based environmental pollution by increasing the level of fertilizer use in agricultural production.

“…Since Brush and Turner's (1987) work, and building on pioneering research on induced innovation (Binswanger & Ruttan, 1978;Pingali, et al, 1987), 7 a host of studies have indicated the importance of diverse spatial and temporal intensification responses to demographic and non-demographic demands, including the use of irrigation, farm machinery and agrochemicals (Nietschmann, 1979;Zimmerer, 1991Zimmerer, ,1993Netting et al, 1993;Behrens et al, 1994;Bilsborrow & Geores, 1994;Connelly, 1994;Krautkraemer, 1994;Schelhas, 1996;Turner & Ali, 1996;Ahmed & Sanders, 1998;Shriar, 2000).…”

Forest conversion for agriculture expansion is the most salient signature of human occupation of the earth's land surface. Although population growth and deforestation are significantly associated at the global and regional scales, evidence for population links to deforestation at micro-scales-where people are actually clearing0020forests-is scant. Much of the planet's forest elimination is proceeding along tropical agricultural frontiers. This article examines the evolution of thought on population-environment theories relevant to deforestation in tropical agricultural frontiers. Four primary ways by which population dynamics interact with frontier forest conversion are examined: population density, fertility, and household demographic composition, and in-migration.
