Exploring the virtual resources flow along supply chains and the coupling relationship among different resources is important for promoting sustainable agricultural development. In this study, by combing environmentally-extended multi-regional input-output (EEMRIO) and structural decomposition analysis (SDA) methods, we analyzed the transfer of agricultural virtual water, land and carbon emissions in China's regional trade and identified the hidden driving forces. We further explored agricultural water-land-carbon nexus evolution characteristics in different development scenarios. The results showed that trade-embodied agricultural land, water use and carbon emissions increase by 8.5 %, 15.4 % and 27.3 % from 2007 to 2017 respectively. The flow trend is mainly from water-starved northern China to southern and southeastern China. Virtual water flows reduce 41.5 % and embodied carbon emissions reduce 31.9 % after the improvement of water use efficiency and reduction of carbon intensity in 2030 under the W2LC2 scenario, where faces the least water-land-carbon pressure. The results provide important information for alleviating the inequality of regional resource and environmental pressure in China. [Display omitted] [ABSTRACT FROM AUTHOR]

This study analyses the income effects of farm households' conservation tillage adoption on agricultural income in China. Based on survey data of 704 farm households from Jianghan Plain, central China, Heckman two-stage and propensity score matching models are employed to quantitatively measure the income effect of farm households' adoption of rice and fish co-cultivation, including six aquatic animals. The results reveal that most farmers have adopted rice and fish co-cultivation methods, but with limited adoption intensity. The number of farmers engaged in co-cultivation and farmers' degree of knowledge and cognition significantly influence adoption and increase adoption intensity. Compared with the non-adoption group, the agricultural income of rice and fish co-cultivation system adoption improved adopters' incomes by 35.15%. In conclusion, rice and fish co-cultivation publicity, technical training and compensation are highly beneficial and recommended. • Most farmers have adopted rice and fish co-cultivation technology. • Farmers' rice and fish co-cultivation technology adoption includes roughly two stages: whether to adopt or not and adoption intensity. • Rice and fish co-cultivation substantially increase rural households' agricultural income.

Community is the disaggregated unit to reflect the transformation of eco-urbanization in China. Eco-urbanization at communities is the ecological landscape and environment-friendly practices, and is directly reflected in residents' satisfaction on the transformation of these ecological elements. In this study, we assess resident's perception of eco-urbanization at community and explore the influencing factors by a field survey in 64 community block groups with 668 questionnaires. Methodologically, we have made the assessment using residents' satisfaction on green space, sanitation, landscape, noise pollution treatment, and optic pollution control. Then regression analysis has been made with the influencing factors from the dimensions of individual characteristics, management, and facilities. In general, residents' satisfaction on sanitation is at the highest level and noise pollution treatment is at the lowest level. The property management and the safety sense greatly influence the residents' perceptions, whereas facilities appear to have less influence. The environmental environment friendly behavior also affects residents' satisfaction on eco-community. The results have also revealed resident's perception of eco-urbanization at community shows great difference in different regions and in different community types. Accordingly, it is necessary to strengthen the comprehensive governance on eco-community, enhance the all-around management and promote human-oriented community in the future. • We assess residents' perception of eco-community and explore the influencing factors by a field survey nationwide. • Residents' satisfaction on green space, sanitation, landscape, noise and optic pollution control is investigated. • Influencing factors are selected from the dimensions of individual characteristics, management, and facilities. • The property management and the safety sense greatly influence the residents' perceptions. • Resident's perception of eco-community shows great difference in different regions and in different community types.
