Active since 2016 and developed by Pakistan Council of Research in Water Resources (PCRWR) in collaboration the University of Washington (UW) and NASA, the Irrigation Advisory is an SMS based advisory service for farmers in 40 districts of Pakistan. The UW is providing real time daily Potential Evapotranspiration (ET) and precipitation for entire Pakistan using NASA’s remotely sensed data. PCRWR determines crop coefficients (Kc) for different crops in different agro-climatic zones of Pakistan and throught this advisory informs farmers about their net weekly irrigation requirements, considering ET and precipitation. These advisory SMS messages are in local languages and come from a fully-automated system that does everything from downloading publicly available satellite data and distributing the text messages to using models to compute how much each farmer needs to irrigate. It covers all major crops including wheat, cotton, rice, sugarcane etc and after feedback from farmers, banana, papaya and chilli crops have been included into advisory.
