"Enhancing total factor productivity in China’s crop production: Contributions to food and environmental security" by Wang, Xiaoxi, Ruiying Du and Bin Lin Abstract Enhancing total factor productivity (TFP) in crop sector is an efficient measure toward ensuring food/environmental security in China and thus is crucial to predict the growth of TFP, which will deepen the understanding of food-environmental security interplay under different shared socioeconomic pathways (SSPs) in the future. This study combined an agro-economic land system model with the TFP calculation method to estimate China’s TFP changes in crop sector based on different future socio-economic scenarios, thereby elucidating the impact of TFP on various aspects of the food and environmental security. The TFP of crop sector in China is estimated to continue growing but vary across different scenarios, of which SSP5 has the highest TFP growth (110.9%), followed by SSP4, SSP1, SSP3, and SSP2. TFP’s growth in the crop sector ensures food security by lowering consumer prices and promoting self-sufficiency. However, SSP1, SSP4, and SSP5 will have higher consumer prices by 2060 than SSP2 and SSP3 by about 2% due to trade. The simulations also indicate that TFP’s growth is accompanied by a reduction of cropland, which helps alleviating water scarcity and reducing greenhouse gas emissions, while land use change also creates new carbon sink. |
