Coastal-zone sustainability policies are socially constructed It follo
ws that their effective implementation depends on the sustainable volu
ntary co-operation of stakeholders with competing interests and priori
ties. No form of integrated coastal-zone management can nurture such c
o-operation as long as the objective is to determine 'best' policies,
derived by expert-based rational analysis, instead of seeking to ident
ify 'correct' policies, ones that can draw the maximum possible stakeh
older support. The latter task requires a cc-operative coastal-zone ma
nagement that incorporates the relevant public discourse into the poli
cy formation process in a direct, proactive and conflict minimizing ma
nner: Towards this end, four major challenges are examined for maximiz
ing the stakeholders' motivation for voluntary co-operation: (I) optim
ism about the level of optimism; (2) agenda setting; (3) value discour
se; and (4) information and empowerment. (C) 1998 Academic Press Limit
