Updates on following

• Agro-Ecozone selection in the study area

• LDA at new Ag-eco zone level

• Data hunting

Ag-eco zones (AEZ) in the study area• According FAO-GAEZ layer of ‘Reference length of growing period’, total 16 classes fall in the study area

• These 16 classes are aggregated to get 8 classes as follows:
