ABSTRACT The grain production growth pathways transition can achieve the dual strategic objectives of increasing and ensuring ecological security by adjusting input structure factors. However, current understanding patterns driving mechanisms remains inadequate, posing challenges to sustainable production. To address this research gap, study establishes a theoretical analysis framework, proposes methods for identifying partitioning, uses panel data reveal transition. main findings indicate that induced substitution directly causes shift in from being driven improvements land productivity labor productivity. This process shows significant differences among crop types regional spatial heterogeneity. primary contribution is its comprehensive behind perspective evolution includes economic‐social, socio‐institutional, environmental‐site dimensions drivers, which influence factors thereby drive We recommend formulating planting plans based on stages implementing differentiated targets subsidy policies various crops regions. These recommendations are valuable promoting

Afforestation on Abandoned Croplands in China Has the Potential to Increase Carbon Sequestration by half

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

Afforestation of abandoned cropland represents a promising strategy for land-based climate change mitigation, particularly in regions where land resources additional afforestation are limited. However, the carbon sequestration potential such remains largely unknown. Here, we assess spatial distribution China and its through incentives, using 10,818 empirical data derived from 298 peer-reviewed articles, multisource remote sensing data, machine learning models. We identify 6.03 Mha that have been undergoing natural regeneration since early 21st century. This has to sequester an 215.12–218.94 Tg biomass 15.87–17.64 soil organic (SOC) by 2060, representing 51.95–53.94% increase compared alone. Our results further show benefits could offset 47.71–49.57% government investments (approximately USD 16.254 billion) cropland. findings highlight significant on support China’s neutrality goals, while also offering cost-benefit framework guide policy decisions.

Does farmland transfer exacerbate non-grain production? Evidence from county-level panel data in Chongqing, China

Cogent Food & Agriculture, Journal Year: 2024, Volume and Issue: 11(1)

Published: Dec. 27, 2024

This study conducted a theoretical analysis of the pathways and mechanisms through which farmland transfer influences non-grain production, utilizing county-level panel data from Chongqing, China, spanning 2018 to 2022. Exploratory spatial (ESDA) random-effects models were employed reveal characteristics production (NGPFT). The findings indicated: (1) NGPFT in Chongqing showed significant clustering, with high values Metropolitan Developed Economic Area low Three Gorges Reservoir Urban Agglomeration. (2) Farmland didn't directly cause but adjustments factors changes recipients indirectly affected it. (3) Higher farmland-transfer rents exacerbated trend towards production. (4) There was heterogeneity impact different on Specifically, ordinary farmers had inhibiting effect while agricultural enterprises other entities positive effect. Family farms farmers' cooperatives no impact. Suggestions include harnessing transfer's effects resource allocation, being vigilant against land rents' crowding-out grain preventing large-scale by entities, encouraging farmers, family farms, engage
