Impact of natural resource conservation technology on productivity and technical efficiency in rainfed areas of Southern India

Abstract

This paper assessed the impact of natural resource management technology (NRCT) on productivity and efficiency in maize production using an endogenous switching regression model in rainfed areas of Southern India. We also identified factors influencing adoption of NRCT, and technical efficiency in maize production. For this study, plot-level primary data from 303 farm households cultivating maize on 419 plots were collected. Results show that adoption of NRCT has resulted in an increase in maize productivity by 490 kg per ha and has also reduced technical inefficiency by 28% as compared to non-adopters. Furthermore, access to credit, better extension services and training on natural resource management are crucial factors positively affecting the adoption of NRCT as well as enhancing the technical efficiency of maize production. Therefore, these factors need to be considered when formulating policies and programmes that aim to improve crop productivity in rainfed areas, as well as sustaining natural resources.
