The study continues (again, sans citations, to emphasize the content), saying:
Policy (Integration) is used in this study as an abbreviation of governmental policy, which refers to an intervening and facilitating course of actions of governmental actors to provide intentional guidance to solve the collective issues. However,… policy implies the instrumental settings (such as the minimum lending rates or annual budgets) and the hierarchy of goals behind policies as well as the instruments per se (the techniques applied to achieve policy goals). In that context, policy integration implies that the policy-making process is a joint process as well as the policy's reflection of a combined and comprehensive consideration.
Institutional) Integration in this study primarily involves two types of institutions: those related to spatial planning and those related to flood-risk management. In this case, there are other stakeholders aside from the institutions of planning authority and flood authority that are or could be part of the process, but they are more involved in the policy integration process than institutional integration because they contribute to the comprehensiveness of policy input. From an operational perspective, integration is based on shared context, such as coordinated management of information and material flows and on collective knowledge and mutually beneficial goals or interests.
