Impact of shallow tubewell irrigation on crop production in the terai region of Nepal

Abstract

This study investigated the economics of irrigation, examined its impact, and analyzed the nature of technological change in rice production with different modes of access to shallow tubewell (STW) irrigation. Data were gathered from 162 STW owner and 162 non-owner households in the Terai region of Nepal. Costs and returns analysis and Cobb-Douglas type of production function were employed to analyze the data.

STW irrigation had a significant positive effect on cropping intensity, rice productivity, farm income, and employment. Furthermore, it promoted cash crop-dominated cropping patterns, expedited adoption of modern crop varieties, and provided irrigation security during drought. Due to availability of water supply, the rice production function of STW owners has a higher intercept and slope of the production function of water purchasers than that of rainfed farmers. STW ownership was found skewed toward the large farmers who reaped the major benefits of STW irrigation. Popularizing group ownership of STWs with 60% government subsidy and among rainfed farmers and the enhancement of its overall benefits to bring about a more widespread impact on food security and poverty alleviation.
