The Economic Value of Gas Exchange in a Paddy Field Ecosystem Using Water-Saving Irrigation

Abstract

Although the main function of rice fields is to produce rice, they also provide a range of other ecosystem services [1], including O 2 production, CO 2 reduction, summer temperature cooling, flood mitigation, and so on [2]. Meanwhile, paddy fields have a negative effect on the environment through greenhouse gas emissions and agricultural non-point pollution [3-4]. Much literature has evaluated these ecosystem services by rice paddies, and these results show that rice fields provide more positive values in maintaining the sustainability of a regional or even global ecosystem [5-7]. Ecosystem services have been recognized throughout the rice-growing world and been considered in agricultural policy-making [8-9].

Research on the application of water measuring technology in water-saving irrigation

“…However, the actual situation is that agriculture occupies more than half of the water use, and the benefit is not as good as industry. Although agriculture is the basis of life, in this trend, in the future, industrial water use will crowd out agricultural water use [4][5]. At the same time, with the progress of society, human life, industry, agriculture, and environmental water demand are increasing, and water consumption and sewage generation are also growing [6][7].…”
