Abstract:
Water scarcity, land pollution, and global warming are serious challenges and crises facing the development of sustainable or green agriculture and need to be addressed using efficient and environmentally friendly management strategies. This paper proposed an integrated framework appropriate for agricultural green total factor productivity (AGTFP) assessment coupled with microscopic and mesoscopic perspectives under water-energy-food (WEF) nexus, which generated scientific and reasonable strategies for green and low-carbon agriculture from internal core factors and peripheral environmental impacts to improve green agricultural production sustainability. Taking the Lianshui irrigation district (LID) with three sub-areas as the object, internal core factors were explored by partial least squares regression (PLSR) and the external impact path through partial least squares structural equation modeling (PLS-SEM). Results indicated that AGTFP in LID was the smallest (0.818) compared to the three sub-areas and was in a fluctuating state. Meanwhile, AGTFP which was calculated considering undesirable outputs, was closer to tangible productivity. Resource endowments and technical facilities will promote agricultural production, desirable outputs will stimulate green production, and undesirable outputs can inhibit green production. The external influence pathway was shown to be primary environment - > secondary environment - > economic aspects - > social aspects - > AGTFP. The innovative perspectives presented in this study can facilitate preferable decisions and avoid unintended consequences for human-natural systems.
摘要:
缺水,土地污染,全球变暖是可持续或绿色农业发展面临的严峻挑战和危机,需要使用高效和环境友好的管理战略来解决。本文提出了一个适用于农业绿色全要素生产率(AGTFP)评估的综合框架,结合水-能源-食品(WEF)关系下的微观和中观视角,从内部核心因素和周边环境影响两方面产生科学合理的绿色低碳农业战略,以提高绿色农业生产的可持续性。以涟水灌区(LID)三个分区为对象,通过偏最小二乘回归(PLSR)探索内部核心因素,通过偏最小二乘结构方程模型(PLS-SEM)探索外部影响路径。结果表明,与三个子区域相比,LID中的AGTFP最小(0.818),并且处于波动状态。同时,AGTFP是在考虑不良产出的情况下计算的,更接近有形生产力。资源禀赋和技术设施将促进农业生产,理想的产出将刺激绿色生产,和不良产出会抑制绿色生产。外部影响途径被证明是主要环境->次要环境->经济方面->社会方面->AGTFP。本研究中提出的创新观点可以促进更可取的决策,并避免对人类自然系统造成意外后果。
