Structural characteristics and influencing factors of agricultural carbon emissions spatial correlation network: evidence from Shandong Province

Frontiers in Sustainable Food Systems, Journal Year: 2025, Volume and Issue: 9

Published: April 2, 2025

Introduction With the development of agricultural industry clustering and scale expansion, carbon emissions (ACEs) have gradually formed a spatial association network. Clarifying correlation network (ACESCN) its influencing factors in Shandong Province is crucial for advancing low-carbon development. Methods Based on ACE 16 cities Province, this study uses Social Network Analysis (SNA) Quadratic Assignment Procedure (QAP) to investigate spillover effects driving ACESCN from 2010 2022. Results discussion The findings show that following: (1) overall, has shown trend initially increasing then decreasing. (2) improved both connectivity robustness, forming structure centered around Weifang, Jinan, Tai’an. However, degree remains relatively loose, indicating needs optimization. Within network, there are significant agglomeration effects. (3) Geographical proximity, economic level, industrial structure, opening-up impact correlation. Therefore, suggests associations should be fully utilized enhance cross-regional production interactions cooperation. This approach will help form rational providing scientific basis achieve regional coordinated emission reductions.

Abstract There are many fertilizer additives and alternatives that aim to increase plant nutrient use efficiency reduce losses the environment, here referred collectively as enhanced fertilizers (EEFs). However, there is often insufficient published scientific field trial results across a variety of locations, climates, soils, cropping systems, management scenarios prove their efficacy conditions for use. Guidelines common minimum datasets data stewardship in evaluating agronomic performance environmental impact EEFs needed researchers follow. Such guidelines will improve hypothesis testing centered on product provide producers with guidance how these technologies function perform when integrated other practices within 4R Nutrient Stewardship Framework. A committee was formed develop set protocol replicated, plot‐based trials an international scale. The composed experimental design core metadata, crop soil analyses, loss measurements, stewardship, include both recommended required components allow flexibility adaptability depending location, objectives, infrastructure capacity, type, depth understanding potential EEF efficacy. This approach ensure consistency compatibility collection support integration, analysis, reuse leading large‐scale end‐user confidence.
