The success of a WSI process depends on the implementation of activities or measures defined through collaborative planning and decision-making with the purpose of addressing and mitigating priority water risks now and in the future. Implementation produces tangible results that improve water security; builds capacity and teamwork through participation; and anchors water security planning and decision-making in knowledge and evidence of what works.
Key considerations for implementing water security actions embrace and reinforce principles and themes of the entire WSI process. These include delivering "quick wins" and early results; effective communications and adaptive management; accountability by mobilizing promised resources and fulfilling responsibilities defined in action plans; and complying with regulations. A wide range of tangible actions and measures can improve water security. These can be broadly listed under four categories: gray as well as green infrastructure; policy, regulatory, and institutional measures; and social and behavioral change measures.
