The ECCA methodology involves the following five interfaces:

• The expert-youth interface (Counsellor Training Camp, CTC)
• The youth-to-youth interface (Urban youths, who get trained from experts or those who are graduates on Environment Science, train rural local youths)
• The youth-children interface (ECCA Children Camp)
• The child-to-child interface (Trained children conduct activities for other students (through nature club) in the same school or in neighboring schools)
• The children - community interface
