Résumé partiel
Grassland degradation is now a major environmental problem in northern China,with heavy stocking rate implicated as one of the prominent causes.Depending on the severity of degradation,partial or total exclusion of livestock grazing has been applied to achieve restoration.However,the socioecological factors causing the overstocking of grasslands is less studied.Here,the empirical evaluation of the risk-induced factors driving overgrazing on grasslands in northern China was studied.This study broadly focused on the following objectives : 1)the overgrazing behaviour of Inner Mongolia herders across the first phase of the Chinese Grassland Eco-compensation Policy(i.e.,subsidy and reward policy)program(2010–2015) ;2)the effect of supplementary feed on the stocking rate used across grassland farms in Inner Mongolia ;3)the factors affecting the size of rented land and its relation to livestock production and income,and ;4)the choice of herders’ livelihood strategy with respect to livestock production and marketisation from the standpoint of rural and pastoral development.The study draws on the panel data collected from a two-wave household survey in 2010(n=1000)and 2015(n=900),as well as the face-to-face-interview conducted in 2018(n=450)across the grassland ecosystem types in Inner Mongolia Autonomous Region(IMAR).In the empirical analysis,linear mixed–effects model,multivariate linear regression model,stepwise multiple linear regression model,analysis of variance,Pearson’s correlation,multinomial logistic regression,and descriptive statistics were applied to address the objectives of the study.For the first objective,the final linear mixed-effects model revealed that the major drivers of stocking rate(SR)prior to the subsidy and reward policy implementation are the area of grassland contracted,living expenses,and the area of grassland rented-out.Subsequent to the policy implementation,the area of grassland contracted and the area of grassland rented-in emerged the principal factors that induce herders to use high SR on grassland,indicating the persistence of overgrazing.This implies that reducing livestock number in order to decline
