The Small Earth Nepal (SEN) is a non-governmental and non-profit organization (NGO) established in March 2001. The key objective of SEN is to promote sustainable lifestyles through education and promotion of activities that reduce adverse impacts on the environment. SEN especially aims to motivate youth and students by organizing a variety of programs to motivate them through its Students-Teachers-Scientists (STS) network. SEN is committed to achieving a balance in human-environment interactions through original research that enhances the knowledge framework that provides the reference to both policy and advocacy processes and through diffused activities that affect changes in the everyday lives of individuals regardless of background.
