Dynamic Linkages among Climate Change, Mechanization and Agricultural Carbon Emissions in Rural China

Abstract

Climate change has become a major environmental issue facing all countries, having a significant effect on all aspects of agricultural production, such as the agricultural mechanization process and fertilizer use. Greenhouse gases produced by agricultural machinery and fertilizers during agricultural production are an important cause of climate change. On the basis of the above facts, researching the connection between agricultural mechanization, climate change, and agricultural carbon emissions is crucial for the development of low-carbon agriculture and for addressing climate change. We used a variety of econometric models and methods to analyze data from China’s multiple provinces (cities) covering the years 2000 through 2019, in order to meet the research objectives. Furthermore, we utilized rainfall and sunlight as variables to assess climate change and adopted Granger tests to establish the link between rainfall, sunlight, agricultural mechanization, and carbon emissions in farming. The findings indicate a bidirectional causality relationship between rainfall, sunlight, agricultural mechanization, and carbon emissions in farming. Rainfall and sunlight are Granger causes of agricultural mechanization. Furthermore, agricultural mechanization has favorable effects on carbon emissions of agriculture, and climate change has long-term implications on agricultural mechanization and carbon emissions of agriculture. Finally, this paper investigated the green path suitable for the low-carbon development of Chinese agriculture, arguing that the government should formulate low-carbon agricultural policies by region and actively promote the upgrading of agricultural machinery.

Analysis of spatial and temporal pattern changes and spatial spillover effects of regional agricultural carbon emission efficiency-Taking the Yangtze River Economic Belt as an example

“…ACE can be accounted for after determining the source of carbon emissions. The most popular approach to quantifying greenhouse gas emissions is the IPCC inventory method, which uses the emission factors speci ed in the guidelines to calculate emissions per unit of activity while also accounting for the level of human activity (Yang et al 2022b). Huang selected chemical fertilizers, pesticides, irrigation, agricultural lm, diesel, and paddy elds as carbon emission sources to calculate the ACE in Heilongjiang Province(Huang &Zhang 2022).…”

Can Land Circulation Improve the Health of Middle-Aged and Older Farmers in China?

“…Although there may exist a positive relationship between land circulation and mechanization, let us also note that mechanization, which normal involves fuel usage, can could lead to a climate change problem if not applied properly [11,12]. Thus, as nations seek remedies for healthy living among older farmers, it is essential for these nations to use agricultural machinery based on climate conditions and guide mechanization following a requirement to control carbon emissions while ensuring healthy living [13].…”
