The emission hotspots were mainly concentrated in the Huang-Huai-Hai region and the middle and lower reaches of the Yangtze River. The water requirement (ET_c) of the three crops increased significantly with time and showed a reverse pattern with the spatial distribution of cGHG. The high ET_c values areas were concentrated in the central part of the study area and the western part of Inner Mongolia, and the water deficit was also the most serious.</div></div><div><h3>SIGNIFICANCE</h3><div>This study clarifies long-term trends and spatial variations in water‑carbon fluxes, providing essential data to inform climate adaptation strategies in agriculture, water conservation efforts, and emissions reduction initiatives.</div></div>","PeriodicalId":7730,"journal":{"name":"Agricultural Systems","volume":"225 ","pages":"Article 104293"},"PeriodicalIF":6.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143518932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The implementation and design of agricultural weather insurance subsidies vary considerably from country to country.

For example, some federal states do not subsidise weather insurance, and other federal states that do subsidise weather insurance, differ in which crops or perils are supported. This insurance subsidy mosaic increases inequality across farms and is likely to increase the cost of insurance. In addition, small federal-state-specific insurance markets are less attractive to insurance companies, which has a negative impact on competition among insurance companies and innovation in insurance products.
