.CommunityandAdvantagesofParticipation
Conceptssuchas‘community’and‘communityparticipation’havebeenintensivelyproblematizedinrecentdecadesinbothdevelopedanddevelopingcountries.Contextsareindeeddifferentandvaried[5].Theword‘community’isanumbrellatermthatisdefinedandappliedinamyriadofways[6].
Citizenparticipationis,however,alotmorethanjustconsultingpeopleforthesuccessfulresolutionofsocial,culturalandeconomicissuesrelatedtoenvironmentalconflicts.Theprimarygoalofparticipationistogiveproperresponsibilitytopeoplefor,andcontrolover,theirlives[7].Theimportanceofcommunityparticipationhasbeenemphasizedinthe5thDevelopmentPlanofIslamicRepublicofIranthathighlightedthenecessitycommunity-orientedapproaches,especiallyinlandscapearchitecture.
