Several issues need to be addressed while developing a crop yield estimation model, including data quality issues, data processing issues, selecting a suitable machine learning model that can learn from few available time-series data, and understanding the non-linear relationship between historical crop yield and remote sensing and meteorological factors. This study applied a series of data processing techniques and a customized ML model to improve the accuracy of crop yield estimation at the district level in Nepal. It was found that remote sensing-derived NDVI product alone was not sufficient for accurate estimation of crop yield. After incorporating other meteorological variables into the ML models, estimation accuracy improved dramatically. Along with NDVI, the meteorological variables of rainfall, soil moisture, and evapotranspiration also exhibited a strong association with rice yield. This study also found that stacking multiple tree-based regression models together could achieve better accuracy than benchmark linear regression or standalone ML models. Due to the unique and distinct physio-geographical setting of each district, a variation in estimation accuracy from district to district could be observed. Our data processing and ML model workflow achieved an average of 92% accuracy of yield estimation with RMSE 328.06 kg\/ha and MAE 317.21 kg\/ha. This methodological workflow can be replicated in other study areas and the results can help the local authorities and stakeholders understand the factors affecting crop yields as well as estimating crop yield before harvesting season to ensure food security and sustainability.<\/jats:p>","DOI":"10.3390\/rs15092374","type":"journal-article","created":{"date-parts":[[2023,5,1]],"date-time":"2023-05-01T12:10:03Z","timestamp":1682943003000},"page":"2374","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["Rapid Rice Yield Estimation Using Integrated Remote Sensing and Meteorological Data and Machine Learning"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1174-2336","authenticated-orcid":false,"given":"Md Didarul","family":"Islam","sequence":"first","affiliation":[{"name":"Center for Spatial Information Science and Systems, George Mason University, Fairfax, VA 22030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3953-9965","authenticated-orcid":false,"given":"Liping","family":"Di","sequence":"additional","affiliation":[{"name":"Center for Spatial Information Science and Systems, George Mason University, Fairfax, VA 22030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0434-652X","authenticated-orcid":false,"given":"Faisal Mueen","family":"Qamer","sequence":"additional","affiliation":[{"name":"International Center for Integrated Mountain Development, Lalitpur 44700, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sravan","family":"Shrestha","sequence":"additional","affiliation":[{"name":"International Center for Integrated Mountain Development, Lalitpur 44700, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9684-0204","authenticated-orcid":false,"given":"Liying","family":"Guo","sequence":"additional","affiliation":[{"name":"Center for Spatial Information Science and Systems, George Mason University, Fairfax, VA 22030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7753-2270","authenticated-orcid":false,"given":"Li","family":"Lin","sequence":"additional","affiliation":[{"name":"Center for Spatial Information Science and Systems, George Mason University, Fairfax, VA 22030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy J.","family":"Mayer","sequence":"additional","affiliation":[{"name":"Earth System Science Center, The University of Alabama in Huntsville, 320 Sparkman Drive, Huntsville, AL 35805, USA"},{"name":"SERVIR Science Coordination Office, NASA Marshall Space Flight Center 320 Sparkman Drive, Huntsville, AL 35805, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aparna R.","family":"Phalke","sequence":"additional","affiliation":[{"name":"Earth System Science Center, The University of Alabama in Huntsville, 320 Sparkman Drive, Huntsville, AL 35805, USA"},{"name":"SERVIR Science Coordination Office, NASA Marshall Space Flight Center 320 Sparkman Drive, Huntsville, AL 35805, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"812","DOI":"10.1126\/science.1185383","article-title":"Food Security: The Challenge of Feeding 9 Billion People","volume":"327","author":"Godfray","year":"2010","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"14168","DOI":"10.1038\/s41598-022-18193-w","article-title":"Evaluating contributions of urbanization and global climate change to urban land surface temperature change: A case study in Lagos, Nigeria","volume":"12","author":"Guo","year":"2022","journal-title":"Sci.
