Rice, thee staplee food food over half thee population, requires consistent water vavability, often necessitating standing water in paddy fields. Thus, monsoun considerarities can drastically fefelt yields. During sharek monsoun years such 2009 as 2009 and 2015, India experively d distarant drops in agrittural output, triggering price spikes anrural economic distres.
