There is high agreement in more recent studies that linked the frequency and extent of the El Niño phenomenon with global warming  that can trigger substantial loss in crop and fishery production. The 2004 El Niño caused the Philippines an 18% production loss during the dry season and a 32% production loss during the wet season . In the 2015 El Niño event, the Indian oil sardine fishery declined by more than 50% of previous years  severely impacting coastal livelihoods and economies . The 2015-2016 El Niño also inflicted adverse impacts on agricultural productivity and food security, especially affecting the rural poor in middle- and lower-income countries in Southeast and South Asia .
