The Nepal Environment and Humanitarian Action (EHA) country-level study is one in a series of studies undertaken by the United Nations Environment Programme (UNEP) / UN Office for the Coordination of Humanitarian Affairs (OCHA) Joint Environment Unit (JEU) in 2015 that assesses the extent to which environmental concerns have been mainstreamed in humanitarian action. It provides guidance to humanitarian actors on how to improve environmental mainstreaming in a rapid onset emergency.
