RAD (Resist-Accept-Direct) decision points and triggers for adaptation planning

On this page:

  • Overview
Directional drivers such as climate change are transforming ecosystems globally. The Resist-Accept-Direct (RAD) framework has gained traction within many management communities in response to social-ecological transformation, helping managers consider the full decision space. In this context, managers decide not only which RAD pathway to implement, but also how long to adhere to a given pathway. For example, a manager may accept a slowly changing ecosystem, but at a certain point, decide to begin resisting or directing the change an ecosystem is experiencing. Alternatively, managers may initially attempt to resist ecosystem transformation, but ultimately realize resistance is no longer feasible based on cost or efficacy. These decisions are challenging and encompass broad domains of ecological, social, and financial considerations to determine how long to stay with a given pathway, and when to switch tactics. Here, we introduce the concept of RAD switch points and RAD triggers to help support these decision processes. We use case studies to illustrate how these decisions play out in the real world. Synthesizing across these examples, we delineate key considerations managers may iteratively evaluate when deciding when to change amongst the RAD pathways as ecological, social, or financial conditions change.

Impact/Purpose

Many ecological systems are undergoing rapid change due to shifts in global climate patterns, invasive species, and extreme events such as droughts and wildfire. Maintenance and sustainability of the values provided by ecological systems has typically been a primary goal of ecosystem management; this is the Resist (R) approach within the Resist-Accept-Direct (RAD) framework.  But as systems change, managers are increasingly considering other options, including Accept (A) and Direct (D).  As systems, feasibility of management actions, and desirability of management objectives continue to change, Resist-Accept-Direct (RAD) pathways may need to switch to balance current and future value of the systems.  This presentation will outline ways in which managers may consider ecological and social information to identify RAD triggers and pathways that can help proactively align the timing of challenging ecosystem decision points.
