Nitrogen and salinity limit crop yield and net economic benefit in coastal saline-alkali soils. Binary quadric surface equations can be used to optimize wheat-corn cropping under saline and nitrogen conditions. Nitrogen addition based on environmental and farmers’ benefits was reduced by 40.4% and 33.9% comparing to traditional dose. Area-specific nitrogen application strategy is needed in coastal saline soils in China.

Farmland plastic pollution is increasing with the use of agricultural mulch film. An empirical study focused on smallholder farmers with national representative samples. National representative micro-level data was used to explore the effect of village regulations. Village regulations have significant direct and indirect positive effects on mulch film recycling.

Discarding waste pesticide bottles are causing environmental problems in rural China. 48.80% of households disposed of waste pesticide bottles in situ in rural China. The measures from government and market had positive effect on proper disposal. Soft constraints did not show significant effect. Synergies between the different policies have not yet been achieved.

Mismanagement of mulch film is causing environmental problems in rural China. National representative micro-level data was used to explore influencing factors of cognition. Half of farmers think that the agricultural mulch film can pollute farmland. The attitude, subjective norm, perceived behavioral control and household characteristics affect cognition. Pay attention to village regulations, not just formal institution.

The selection of mulch film thickness is decisive for the clean utilization of mulch film. Nationally representative data were used to analyze mulch film thickness selection. The selection of mulch film thickness is influenced by market factors and farmers’ product cognition. It is beneficial to strengthen subjective norms of farmers and improve farmland property rights.

Mulch film itself is not the primary source of MMPs in terms of abundance. Use history of mulch films was inversely correlated to the particle size of MMPs. Use history of mulch films was positively correlated to the abundance of MMPs. Questionnaire survey and soil sampling were integrated properly for MMPs pollution.

In 2018 in rural China the average household carbon footprint is 2.46 tons CO2-eq per capita, which is around one third of China’s average footprint, indicating the large potential for further growth. Housing (45.32%), transportation (20.45%), and food (19.62%) are the dominant contributors for carbon footprint. Carbon intensity decrease could significantly reduce carbon footprints, but increase inequality. More comprehensive measures reduce carbon footprint and inequality.
