Abstract
Rice is one of the staple foods across the world, thus information about its production is essential for ensuring food security. Here, our objective was to develop a method for mapping "boro" rice (i.e., cultivated during the months January to May) in a Bangladeshi context. In this paper, we used a Moderate Resolution Imaging Spectroradiometer (MODIS)-derived 16-day composite of normalized difference vegetation index (NDVI) at 250 m spatial resolution in conjunction with ancillary datasets (i.e., land use map, crop calendar, and ground-based rice production information) during the period 2007-2012. The proposed method consisted of three procedures: (i) ISODATA clustering and determining the boro rice signatures in temporal dimension using data from the period 2007-2009; (ii) formulating a mathematical model for extracting the boro rice areas using data from the period 2007-2009; and (iii) model calibration using data from the period 2007-2009 and its validation using data from the period 2010-2012. The implementation of the abovementioned procedures revealed reasonable agreements between the model (i.e., MODIS-based) and ground-based estimates of boro rice area at both country (i.e., percentage error in the range -0.83-1.42%) and district levels (i.e., r(2) in the range 0.69-0.89) during the period 2010-2012. Our proposed method demonstrated its effectiveness in mapping rice system at the regional/country scale.
