Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'The VDSA panel dataset (vdsa.icrisat.ac.in) was generated by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in partnership with the Indian Council of Agricultural Research (ICAR) Institutes and the International Rice Research Institute (IRRI). The VDSA has operated over a total period of 40 years from 1975 to 2015 but with discrete periods of data collection. In the most recent period (2009-2014), the period used for this analysis data were collected for a larger number of households and with vastly increased survey efforts focused on detailed data collection covering production information, GPS-measured plots, and 3-weekly household visits to record input and output data for each plot owned/leased by participants. The resultant data set covers the period 2009 and 2015 with 1,129 households participating ' .
