Assessment of environmental and economic impacts of trickle irrigation system

Abstract

The systems of trickle irrigation offer the potential influential irrigation to increase crop yields and have been proven reasonable according to the engineering and agricultural opinion particularly in barren areas. Trickle irrigation systems that have been offered comparatively lately in Arab countries have demonstrated to save huge amounts of water and enhance crop yield. The computational program (Trickle Irrigation System Design, TISD) connected with the economic procedures were used to research the environmental and economic conditions of the agriculture system. The conditions of environment comprised the type of soil, the topography of land, the climate areas, the water quantum and quality, and the dimensions of land. The conditions of economic included the interest rates of nominal and real, the principal price of land, and the rates of labor and energy escalation. The research deemed the ratio of B/C indicating the effects of environmental and economic parameters applying the system of trickle irrigation. The research presented the crop rotation of tomato-sesame as a line-source, and the point-source was represented by citrus trees. The research results revealed a significant impact on the ratio of B/C for the parameters; soil type, land topography, and water quality. The other parameters evidenced a variety impacts among considerable, small, and negligible on the B/C ratio. The study represents a worthy perception for institutional considerations in agricultural economics.
