The.tsunami.of.26.December.2004.swept.along. rehabilitation.activity..Communities.tended.to.be. 800.km.of.the.coast.of.the.Indonesian.province. included.only.as.workers,.not.as.partners.involved. of. Nanggröe. Aceh. Darussalam. (NAD,. or. Aceh),. actively.and.continuously..Moreover,.coordination. causing.the.loss.of.at.least.167,000.lives..A.further. and.information.sharing.among.the.stakeholders. 500,000.people.lost.their.homes.and.livelihoods. concerned. with. the. rehabilitation. activity. were. very.poor. A.year.later,.as.many.as.124.international.NGOs,. 430. national. NGOs,. dozens. of. donor. and. UN. A.mistaken.perception.among.the.implementers. organizations,.a.variety.of.Government.institutions. was. that. rehabilitation. activity. ended. once. the. and. military. institutions. had. been. recorded,. seedlings. had. been. planted. in. the. field.. The. together. with. the. community,. to. be. working. on. result.as.they.saw.it,.therefore,.was.the.number.of. rebuilding.Aceh.(BRR,.2005). seedlings.planted,.not.the.number.that.survived. after.planting. The.first.step.in.the.reconstruction.effort.focused. mostly.on.the.emergency.response,.particularly. Apart. from. the. matters. mentioned. above,. the. with.regard.to.fulfilling.the.victims’.need.for.basic. coastal.rehabilitation.activities.underway.in.NAD. items.such.as.food,.clean.water.and.shelter.

Unfortunately,.these lessons. emergency.gradually.subsided.and.work.moved. have. not. been. brought. to. the. attention. of. the. to.the.next.phase,.rehabilitation..From.that.point. stakeholders.in.Aceh. For.this.reason,.Wetlands. on,. attention. began. to. be. directed. towards. International-Indonesia.Programme.collaborated. restoration.of.the.environment,.particularly.in.those. with.the.United.Nations.Environment.Programme. areas.hit.by.the.tsunami. (UNEP).to.undertake.this.study.of.lessons.learned. from.coastal.ecosystem.restoration.efforts.in.Aceh. A. number. of. organizations,. both. governmental. since.the.tsunami. and. non-governmental,. initiated. a. variety. of. environmental.restoration.activities,.in.particular.the. In. this. study,. the. causes. of. failures. have. been. planting.of.mangrove.and.other.coastal.vegetation. identified. and. extracted. from. a. variety. of. in.an.effort.to.restore.the.coastlands.

After. 18. months. of. coastal. rehabilitation. activity,. NAD.Province.. the.results.are.now.clear. Only.a.few.activities.of.it. have.been.fully.successful,.the.rest.has.failed. This. can.be.seen.simply.from.the.low.survival.rate.of. plants.in.the.field. Reasons.given.for.the.failures. include:.mistakes.in.the.selection.of.planting.sites,. unsuitable.choice.of.plants,.insufficient.preparation,. inadequate.guidance,.no.tending.of.the.plants,. and.the.low.capacity.of.human.resources. Coastal Ecosystem Restoration: Lessons Learned in Aceh since the Tsunami Executive summary •. that.the.use.of.mature.and.qualified.seed.and. seedlings.is.essential.to.high.survival.rates.after. planting; This.report.explains.what.is.known.about.coastal. ecosystems.in.the.Indonesian.province.of.Nanggröe. •. that.the.choice.of.site.for.nurseries.is.important.
