Article Synopsis
  • Timely estimation of rice yields is essential for food security and agricultural policy development, particularly in countries like Bangladesh, where existing methods lack integration into national reporting systems.
  • This study introduces a new workflow using remote sensing data to estimate boro rice yields at a high spatial resolution of 1,000 meters, achieving a low mean percentage root mean square error (RMSE) compared to district yields.
  • The analysis reveals trends in boro rice yield from 2002 to 2021, showing 23% of the area with an increasing trend, while providing scalable yield estimates that can enhance food security management in Bangladesh.

Unlabelled: The usability gaps between climate information producers and users have always been an issue in climate services. This study aims to tackle the gap for rice farmers in Bangladesh by exploring the potential value of tailored agronomic monsoon onset definitions. Summer rice is primarily cultivated under rainfed conditions, and farmers rely largely on monsoon rainfall and its onset for crop establishment.

High-resolution mapping of rice fields is crucial for understanding and managing rice cultivation in countries like Bangladesh, particularly in the face of climate change. Rice is a vital crop, cultivated in small scale farms that contributes significantly to the economy and food security in Bangladesh. Accurate mapping can facilitate improved rice production, the development of sustainable agricultural management policies, and formulation of strategies for adapting to climatic risks.
