Abstract

This study attempts to quantify farmers' response to output and input prices for irrigation water use to examine the issue of sustainability in sugarcane cultivation in Maharashtra, India. We used a seemingly unrelated regression estimator (SURE) to estimate a translog profit function model. Secondary data on production costs covering the period of 1971–2021 were used. The results show that the sugarcane price affects not only production but also irrigation demand. The elasticity of irrigation demand with respect to the output price is highly responsive (i.e. 1.94), which could be the main reason for groundwater extraction. The continuous increase in the guaranteed price of sugarcane and the relatively lower cost of irrigation motivate farmers to continue sugarcane cultivation. The findings of this study justify significant policy interventions for the sustainable production of sugarcane in Maharashtra.

印度西部甘蔗种植中的取水和可持续性问题：SURE 模型的应用

本研究试图量化农民对灌溉用水的产出和投入价格的反应，以考察印度马哈拉施特拉邦甘蔗种植的可持续性问题。我们使用看似无关的回归估算器（SURE）估算了一个转化利润函数模型。我们使用了 1971-2021 年期间有关生产成本的二手数据。结果表明，甘蔗价格不仅影响产量，也影响灌溉需求。灌溉需求对产出价格的反应弹性很大（即 1.94），这可能是抽取地下水的主要原因。甘蔗保证价格的持续上涨和相对较低的灌溉成本促使农民继续种植甘蔗。本研究的结果证明，有必要对马哈拉施特拉邦甘蔗的可持续生产进行重大政策干预。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
