Abstract
Rural-urban migration in developing countries has required left-behind women to assume the role of key decision makers and take increasing responsibility for agricultural production. However, little is known about the effect of rural-urban migration on fertilizer use when left-behind women assume key decision-maker roles. This study highlights the effect of left-behind women on fertilizer use, drawing on nationwide household survey data in China. The results indicate that households with recognized left-behind women heads use less fertilizer than those with recognized men heads, while households with de facto left-behind women heads use more fertilizer. Moreover, the average nexus between households with recognized left-behind women heads whose major agricultural income comes from grain crops and fertilize use is negative but small in size and statistically insignificant. The findings indicate that future policy efforts aimed at decreasing rural environmental degradation should place greater emphasis on left-behind women's empowerment in socioeconomic decision-making within and outside the household, thereby contributing to an environment in which left-behind women farmers can succeed in a sustainable way.
