Code of conduct for payments for water-related ecosystem services is likely to be of high interest to Ramsar Parties , because it is based on a clear recognition and understanding of the many water-related services that wetlands , and other water-related ecosystems , provide for human well-being . With the advancement of ecological understanding , smart composite indicators are being developed that are both specific and widely applicable , and that may be based on direct measures of relevant ecosystem processes ( from molecular to ecosystem levels ) . The standard vegetation classification system provides the consistent basis for the characterization of the biological components of different ecosystem units . These results are examples of findings that contribute new scientific knowledge about relationships of terrestrial ecosystem processes and management practices on carbon sequestration . They will provide a consistent means for the inventory and monitoring of plant communities and , they will support " ecosystem management " by providing a consistent basis for the characterization of the biological components of different ecosystem units .
