GRF · Diplomacy Nexus
Policy, institutional and decision science is the core method of this platform. It reads treaties, mandates, rules of procedure and implementation records to explain how institutions cooperate across borders, where responsibility for a shared risk is unclear and which arrangements have held under stress.
Policy, institutional and decision science studies how public decisions are made, implemented and evaluated. It examines how institutions coordinate across sectors and levels of government when facing shared risks. In diplomacy and cooperation, water and climate and hazards, policy science identifies governance gaps where responsibility for cross-sector risk is unclear. It supports the design of mandates, coordination mechanisms and accountability. The canonical description is on the STEM Commons.
Basin and environmental treaties are coded for allocation rules, data exchange, notification, joint bodies, dispute settlement and review clauses, so negotiators can see how comparable provisions are drafted and which have been used.
For a shared risk, each body with a mandate is mapped with its legal basis, membership, decision rule and reporting duty, showing gaps and overlaps that no single institution owns.
Commitments in agreements and communiqués are traced to reports, decisions and practice, keeping apart what was promised, what was reported and what independent records show.
Three families of instruments side by side against the baseline, each with its own lag and adoption speed, under the coverage and compliance you set; effect sizes are teaching values to replace with evidence. Scenario: named assumptions about the future, not a forecast.

The model runs on the teaching values set by the controls. To calibrate it for a place, read it against these admitted layers and series, which this page’s map can draw:
Across the six pillars, led by Nexus Consortium
Datasets and records used by policy, institutional and decision science on this platform, with the role each plays and the label its values carry. Sources are listed in the source register.
| Data | Role | Label |
|---|---|---|
| Treaty texts and depositary records | Obligations, parties, reservations and declarations | Published statistics |
| Basin organisation and secretariat records | Mandates, rules of procedure, decisions and meeting reports | Published statistics |
| Coded treaty and agreement databases | Comparable provisions across agreements | ESTIMATED |
| National reports under conventions | Self-assessed implementation | REPORTED |
| Negotiation summaries | Positions and text changes between sessions | REPORTED |
The steps an instrument takes from mandate to evaluation, each with the pillar that runs it, and the decisions that stay with the authority. Teaching model with stated illustrative values, not a prediction.
Across the six pillars, led by Nexus Consortium
Conclusions are tested through comparative cases, counterfactual evaluation and peer review. Implementation outcomes are monitored against stated objectives.
| Check | How it is done |
|---|---|
| Inter-coder reliability | Two coders code a sample of agreements independently; disagreements are resolved and reported before the coding is used |
| Source triangulation | Self-reported implementation is compared with secretariat records and independent sources before it is described |
| Counterfactual caution | Claims that an institution caused an outcome are tested against comparable cases without it |
| Legal accuracy review | Statements of obligation are checked against the treaty text and authoritative interpretation |
Findings are often context specific and difficult to transfer. Political dynamics can override technically preferred options.
The instruments, mandates, actors and accountability arrangements a policymaker, diplomat or development agency works with, citing the agreements that set them. Structures follow the frameworks named. Any state or progress drawn is illustrative, not a record.

Policy Nexus stewards policy, institutional and decision science for the Consortium and reviews how it is applied across platforms.
Reports is the Consortium’s quarterly publication. What you know about this subject can become evidence, a case or a correction in the next edition, credited to you and published under CC BY 4.0 where it is your own work.
