Introduction: The Importance of Scenario Planning for the Chesapeake Bay Watershed

The future of agricultural and environmental conditions within the Chesapeake Bay Watershed is highly uncertain. Agricultural trends point to a decline in cropland alongside an increase in livestock production, leading to imbalances between manure production and available application sites. These shifts are largely driven by market forces that incentivize livestock and feed crop production, while urban expansion pressures farmers to sell their land. Changing weather patterns, labor shortages, and other factors introduce further uncertainty, threatening farm profitability.
Environmentally, the Chesapeake Bay Partnership has struggled to meet key restoration targets. Efforts to cap nutrient and sediment runoff by 2025 have fallen short, and broader restoration goals continue to lag. These setbacks have significant consequences for aquatic habitats, biodiversity, and recreational opportunities.
Scenario development provides a structured approach for stakeholders to explore possible futures, anticipate challenges, and identify opportunities for adaptation under uncertainty. By fostering dialogue and shared understanding, scenarios help participants learn from each other and collaboratively develop long-term strategies. This method is particularly effective for exploring the interconnected dynamics of social-ecological systems, where public policy, environmental forces, and economic trends interact.
Scenarios can take many forms, from qualitative narrative descriptions to spatially and temporally detailed quantitative models. The Thriving Ag project engaged a broad group of stakeholders to develop narrative scenarios that explore pathways to resilience for agricultural-ecological systems in the Chesapeake Bay Watershed. These scenarios help describe community goals and assess different approaches for achieving them. By envisioning a range of potential drivers and outcomes, participants developed shared visions of desirable environmental, economic, and social outcomes to support decision-making toward a more resilient future. Later, these narrative scenarios were integrated with biophysical models to quantitatively evaluate possible outcomes.
An effective scenario planning process incorporates several key elements. Foremost is the need for representative stakeholder engagement. Including participants with varying perspectives ensures that scenarios reflect the complexity of agricultural-ecological systems and represent a broad range of goals. Managing engagement carefully minimizes conflicts and prevents any one viewpoint from dominating the conversation. In addition, evaluating existing and emerging trends using available data, and considering future uncertainty, enhances the credibility and relevance of scenarios. Four scenarios that were evaluated emerged from stakeholder engagement, and the research team introduced a fifth scenario to assess deep uncertainty, which is a method for exploring extreme but plausible changes to a system. This approach provides insight into ways to build resilience in response to highly unpredictable shifts, even if risk cannot be fully managed.
The resulting five scenarios serve multiple purposes, from communication and stakeholder engagement to modeling and policy development. They inform risk assessments and policy strategies by revealing which outcomes matter most to affected communities and whether current trajectories result in a desirable future. Furthermore, translating scenario narratives into quantitative indicators helps deepen understanding of agricultural-ecological systems. Through modeling, decision-makers can evaluate potential strategies, identifying pathways toward preferred futures for the Chesapeake Bay watershed.
