The nine lives of uncertainty in decision-making about complex governance issues

In a governance context, decisions are made by both public and private actors, often in interaction with each other. Decision making about complex governance issues are fraught with uncertainties about the current state of affairs, the relevant set of decision alternatives, the reactions of other governance actors, or the future developments likely to affect the issue under consideration. Uncertainty comes in different kinds, however, and its conceptualization has been fragmented across different fields of study. We argue that the nature of uncertainty consists of three types. Policy analysis involving modelling complex systems such as transport or ecological systems have led to distinguishing between epistemic uncertainty (involving lack of knowledge about a particular system) and ontological uncertainty (irreducible unpredictability is due to inherently complex system behaviour). Studies on the interactive and political processes of decision-making have identified ambiguity as an uncertainty of a rather different nature, consisting of conflicts between fundamentally different frames about the issue at hand. Scholars have also argued that there is it important to differentiate between different objects of uncertainty. First, substantive uncertainty, or uncertainty about the content of decisions or policy issues. In addition, network governance scholars have pointed to the importance of strategic uncertainty which refers to the uncertainty about the actions of other actors in the strategic game of decision-making, and institutional uncertainty, which refers to uncertainty about the rules of the game in decision-making. In this paper, we bring together different strands of the uncertainty literatures to present a novel analytical framework that allows to combine the three different natures of uncertainty (epistemic, ontological and ambiguity) and the three objects of uncertainty (substantive, strategic and institutional), providing a comprehensive framework for analysing and addressing the nine lives of uncertainty in decision-making. We exemplify how the nine different types allow for tailored intervention strategies to deal with the different types of uncertainty.

Public policy making in many delta system of the world are embarking on adaptive delta management as a promising approach to deal with the intrinsic dynamics and uncertainty that characterizes these systems. Bangladesh is on her way to develop scenario based water-centric adaptive delta plan taking into account future uncertainty in physical and socio-economic developments. Informed decision making on a deeply uncertain future demands for a context specific framework to structure the relevant information of the system and their dynamic relationships. Our objective is to address two key questions: 1) How to analyze the complex dynamic delta system for adaptive decision making under deep uncertainty? and 2) What are the key system components and their dynamic relations for water resource management in the polder systems of southwest coastal Bangladesh? We focused on the polders, which are small embanked but dynamic components of the delta. For this purpose, we adopted the XLRM framework of Lempert et. al. (2003) for scenario development for Bangladesh’ polders. The exogenous uncertainties (Xs), Policy Levers (Ls), Relationships (Rs) and Measures (Ms) were identified from extensive literature review on water resource management, community engagement in policy and practice, community adaptation and livelihood. We utilized field data collected by interviewing farmers to establish this framework. This study demonstrates the dynamic interaction of physical and socio-economic processes, policy response and community response around water resource management in southwest coastal Bangladesh. The major physical system components are climate and hydrologic processes, surface and ground water system, salinity and sediment. These components are influenced by both natural and human actions. The socio-economic activities and policy/ community responses are contributing to socio-economic uncertainty and policy actions resulting for example in specific land use dynamics. The relations reveal that there are certain thresholds which make a specific policy obsolete. Similarly, a gap was identified between the two layers of decision making of public policy and local community, which results in uncertain community responses to public policy actions. Thus, a revision or new strategy is required for both policy regime and community to adapt to the changes in such complex systems. The exploratory approaches that embrace uncertainty are at the heart of adaptive policy making and dynamic adaptive policy pathway. Thus adaptive delta management is well suited to contribute to this revised strategy. We conclude that adaptive decision making can play a key role in facing future uncertainties that unfold in the dynamic interaction of system component. Finally this research work contributes to the scientific knowledge on dynamic interactions of the complex delta system assisting in policy area of water-centric adaptive delta management.

Sea-level rise a game changer for public policy?

Sea-level rise challenges public policy-making because existing institutions have been designed to address uncertainty using static and time-bound planning and legal instruments, and community engagement at fixed points. Sea-level rise is a dynamic and partially uncertain process, especially on long timeframes. It thus requires decision-making approaches that can enable policies and implementation choices that can be adjusted ahead of damage occurring, without entrenching current exposure to risk or incurring large adjustment costs in the future. This paper first discusses the nature of the climate change problem, the policy context that creates decision-making challenges and how they have been typically addressed through policy and practice. Second, it shows how an assessment and planning approach, that was designed to address uncertainty and change (the Dynamic Adaptive Policy Pathways (DAPP) planning approach developed in the Netherlands), was integrated into national level guidance in coastal hazard and climate change decision-making in New Zealand. The framework is presented that has enabled DAPP to be integrated into real-life decision processes. The enabling provisions that are required to support such integration are discussed, such as those that enable the community values at stake to be acknowledged through

engagement processes and their monitoring over time and policy institutions that deal with long-term political commitment and its funding. Initial results are also presented from a case study application of the principles of the Guidance approach. The approach enables dynamic and uncertain future conditions to be managed in an adaptive manner. This gives decision makers the confidence and community support to take initial actions on adaptation to climate change, in the knowledge that there are several pathways that can be chosen in the future with minimum societal disruption. The paper concludes with some suggestions as to the applicability of this approach to other decision domains.
