Greenhouse gas emissions from different plant production system in China

Changes in seasonal weather cycles, a growing number of extreme phenomena, an upward trend in temperature and changes in the distribution of rainfall, significantly affect the functioning and effectiveness of agriculture. However, agriculture plays a major role in the emergence and intensification of these phenomena. The aim of the article is to present, analyse and evaluate the relations between agriculture and climate, with particular emphasis on greenhouse gas (GHG) emissions from agriculture in these relations. A cause-and-effect analysis was conducted based on literature studies, using the descriptive statistics method and analysis of the development trend. The basis for analysis were data on GHG emissions in the European Union (EU-28). The contribution of agriculture to the EU’s greenhouse gas emissions, albeit slightly but still increasing in recent years. The level of this emission is determined primarily by the type of agricultural activity conducted – animal production is definitely responsible for higher emissions than plant production. It is difficult to present a universal model of agricultural adaptation to climate change and a set of actions limiting the negative impact of agricultural production on climate. This is hindered by both the specificity of the agricultural sector and the large diversity of local conditions and applied farming practices. The opportunity to increase the effectiveness of actions taken may be a better connection between the implementation of objectives including the reduction of the causes and negative consequences of climate change and the objectives of sustainable agricultural development.

Harvesting Process

With the aim of evaluation and comparison of the greenhouse gas emissions from soybean and tangerine production in Golestan province, Iran, a pilot experiment was carried out. In this experiment, 43 fields of soybeans and 43 orchard tangerines were selected by various management in the province using questionnaires. The greenhouse gas emissions were examined using the Global Warming Potential (GWP). The results of this study showed that fossil fuel was the highest energy consumption in the production of soybeans (6906.5 MJ ha-1) and tangerines (17205.1 MJ ha-1). The lowest amount of energy consumption among inputs was related to micro fertilizers, that was 9 MJ ha-1 for soybeans and 17.6 MJ ha-1 for tangerine. In both of production system, the most energy consumed was shown for the harvesting sector. Irrigation and planting were the highest contributors to greenhouse gas emissions in soybean field by 387.7 and 109.4 kg CO2 ha-1, respectively; while in the tangerine production, the most greenhouse gas emissions were related to irrigation and harvesting process by 5828.4 and 394.7 kg CO2 ha-1. In general, input energy in soybean and tangerine were 17512.8 and 33879.8 MJ ha-1, total output energy was calculated 48310.5 and 105463 MJ ha-1. Finally, the energy use efficiency was computed for soybean and tangerine 2.9 and 3.3, respectively.
