In this paper we explore the hypothesis that the accumulation of environmental pressures, including erosion, salinization. Soil exhaustion, and degradation of the local environment, may be partially responsible for the recent slowdown of grain yields. Using provincial production data from 1975 [Q 1990. the analysis shows that environmental factors. especially the breakdown of the environment. did contribute to the -decline in the rate of increase of yields in China during the late t 980s. Erosion and 'salinization had a small, negative effect on yields.Text1 digital file (32 p. : ill.)Application/pdfenENVIRONMENTAL DEGRADATIONAGRICULTURAL PRODUCTIVITYSOIL DEGRADATIONAGRICULTURAL ECONOMICSENVIRONMENTAL ECONOMICSECONOMETRIC ANALYSISCROP LOSSESIDRC Final Report
