CASE STUDY QUESTIONS What are the ecosystem services that our Auckland water Clients impact on and depended on ? What risks and opportunities arise to ourselves and our water Clients from the trends in the ability of the natural environment to provide those services and benefits? What actions can we undertake to better support our clients in understanding, minimising and mitigating their impacts as well as managing dependencies?
