Synergistic strategies for recycling livestock manure from perspective of supply-demand
Crop-livestock integration beyond the household level is crucial for enhancing the efficiency of livestock manure recycling(LMR),so it is required to match the breeders'for LMR with neighboring growers'supply for LMR to fertilize the cropland.Using the choice experiment data of pig breeders(the compensation payers)and crop growers(the compensation recipients)in Jiangsu Province,China,the breeder/grower's demand/supply preferences and willingness to pay/accept(WTP/WTA)were obtained according to the principle of"who pollutes,who pays".The results show that:1)A higher LMR price incentivizes the growers'willingness but reduces breeders'willingness to participate in,showing a significant heterogeneity between the two groups.2)Both growers and breeders prefer services at the source and final stages of LMR.In this context,a voluntary market for LMR can spontaneously form because pig breeders'WTP exceeds crop growers'WTA.3)Market simulation based on the samples suggests an equilibrium LMR price between 29～76 yuan per ton,with its market share constituting 2.28%～2.15%of Jiangsu Province's total LMR market.Therefore,it should consider the preferences of both crop and livestock producers while formulating the policies for LMR,promote the development of socialized service organizations,and explore a way to establish a market-based compensation system for LMR beyond the farm level.
