Rainfed systems or rainfed crops are the ones that rely entirely on rainfalls to cover their water needs. These include both annual crops and permanent/perennial crops (like trees).
Rainfed farming constitutes more than 80% of the world’s cropland and produces more than 60% of the world’s cereal grains. (IWMI, 2007)
