Abstract

The Parasitical Systems Analysis & Transformation (PSAT) Framework v3.1.1: Methodological Manual (Ecological Edition) provides a structured tool for diagnosing stress, resilience, and potential collapse in ecological systems. Building on prior versions, v3.1.1 refocuses on ecological applications while retaining a systemic perspective on governance and culture. The framework operationalizes four levers—Institutional Dependency, Institutional Stress Index, Resource Fragility, and Cultural Contestation—each scored on a 0–2 scale and integrated into a weighted 0–100 risk index. This approach balances simplicity and rigor, enabling reproducible assessments across scales. Worked examples demonstrate applicability to species survival, resource governance, and ecosystem transitions under climate stress.

The PSAT v3.1.1 framework helps people understand when ecological systems are under stress and at risk of collapse. It looks at four key factors: reliance on outside rules and authority (Institutional Dependency), how strained governance is (Institutional Stress), how fragile the ecosystem itself is (Resource Fragility), and the level of disagreement over how nature should be valued (Cultural Contestation). Each factor is scored from 0 to 2 and combined into a simple 0–100 risk score. This clear measure supports comparison across cases and helps guide conservation, governance, and climate adaptation decisions in practice.
