PurposeThe objective of this paper is to evaluate the impact of remittance income on rural households in China.Design/methodology/approachUsing data from a large survey of farming households in three Chinese provinces, the impacts of remittances and other types of income on consumption, production expenditures is evaluated. The econometric models used in this study include logit, tobit and ordinary least squares models.FindingsIt is found that remittances increase nondurable consumption, but not as much as local wages and that there is no difference in the impact on agricultural production spending between remittance and local wages. The large majority of remittances are reported by the households of non‐permanent migrants, suggesting that the fear of losing land allocations has a strong impact on migration decision.Originality/valueThe paper uses a large data set from three distinct provinces of China and is among the first to investigate the different types of remittance and their impacts on both consumption and production activities of Chinese rural households.
Abstract-A comprehensive biological, sediment, and water quality study of the lower Little Scioto River near Marion, Ohio, USA, was undertaken to evaluate the changes or improvements in biotic measurements following the removal of creosote-contaminated sediment. The study area covered 7.5 river miles (RMs), including a remediated section between RMs 6.0 and 6.8. Fish and macroinvertebrate assemblages, fish biomarkers (i.e., polycyclic aromatic hydrocarbon [PAH] metabolite levels in white sucker [Castostomus commersoni] and common carp [Cyprinus carpio] bile and DNA damage), sediment chemistry, and water quality were assessed at five locations relative to the primary source of historical PAH contamination-upstream (RM 9.2), adjacent (RM 6.5), and downstream (RMs 5.7, 4.4, and 2.7). Overall, the biomarker results were consistent with the sediment PAH results, showing a pattern of low levels of PAH bile metabolites and DNA damage at the upstream (reference or background location), as well as the remediated section, high levels at the two immediate downstream sites, and somewhat lower levels at the furthest downstream site. Results show that remediation was effective in reducing sediment contaminant concentrations and exposure of fish to PAHs and in improving fish assemblages (60% increase in index of biotic integrity scores) in remediated river sections. Additional remedial investigation and potentially further remediation is needed to improve the downstream benthic fish community, which is still heavily exposed to PAH contaminants. Environ.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
