| Statistical concepts and definition | Provides a comparative analysis of agricultural productivity under two different farming conditions: rainfed and irrigated. This indicator measures the yield efficiency of crops grown with natural rainfall against those supported by artificial irrigation systems. By quantifying the differential in productivity, this indicator highlights the effectiveness of irrigation in enhancing crop yields and the potential vulnerabilities of relying solely on rainfall. |
| Relevance | It helps in understanding the resilience of agricultural systems to water scarcity. Regions heavily dependent on rainfed agriculture may face significant risks during droughts, as reduced rainfall leads to lower crop yields and potentially threatens food security. Conversely, areas with well-developed irrigation infrastructure can maintain or even increase productivity during dry spells, mitigating the adverse effects of droughts. |
