The Global Risks Forum (GRF)
Climate change shifts the hazards that public planning was designed for, while the policies that respond to it cut across energy, land, water, finance and nature. Climate and adaptation policy covers the laws, plans, targets and institutions through which governments reduce emissions and adapt public systems. This page sets out how climate policy risk arises and propagates, how adaptation governance is measured, and which institutions hold the decisions.

Climate adaptation policy is the set of laws, plans, targets and institutions through which governments prepare public systems for a changing climate, alongside mitigation policy that reduces emissions. It cuts across energy, land, water, finance and nature, and its risks include plans without delivery and maladaptation.
For climate and adaptation policy, in GRF's situational-awareness reading, the map opens on population density, daytime surface heat and night lights with a 15-day forecast chart at the centre and surface air temperature from NASA GIBS, framed on Africa; every other NASA layer, live feed and forecast waits in the layer list.

Climate, nature and public planning. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Adaptation plans and climate targets are adopted nationally, but delivery depends on sector ministries, local governments and regulators whose mandates and budgets may not reflect them. The gap shows only when implementation is reviewed.
A measure that reduces one risk can raise another or shift it to others: a sea wall that moves erosion along the coast, or irrigation that deepens groundwater depletion. Without cross-sector appraisal the side effects stay invisible.
Abrupt or reversed policy changes strand assets and raise the cost of capital. Stable, legislated frameworks reduce that risk; frequent reversals transmit it to investors, workers and the regions that depend on them.
Land use, ecosystems and climate interact: degraded wetlands and forests lose their buffering role, which raises flood and heat risk. Policies governed by separate ministries miss these links unless planning duties join them.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Maladaptation | Action that increases the risk of adverse climate outcomes, now or later, in IPCC usage. |
| National adaptation plan | A country's plan, under the UNFCCC process, to identify medium and long-term adaptation needs and how to meet them. |
| Adaptive pathways | A planning approach that sequences actions and sets signals that trigger a switch between them as conditions change. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| National adaptation plan submitted | yes or no, with date of submission | event-based | UNFCCC NAP Central | OFFICIAL |
| Framework climate law in force | categorical, by scope and duties | periodic review | National gazettes, compiled in Climate Change Laws of the World | OFFICIAL |
| Adaptation spending tagged in the budget | share of total expenditure | annual | Climate budget tagging | OFFICIAL |
| Independent climate advisory body with statutory mandate | yes or no, with functions | periodic review | National legislation | OFFICIAL |
| Climate policy adoption and stringency | index score | annual | OECD Climate Actions and Policies Measurement Framework | ESTIMATED |
| Reporting under the Enhanced Transparency Framework | submission status | biennial | UNFCCC biennial transparency reports | OFFICIAL |
| Spatial plans that integrate climate risk | percent of plans reviewed | periodic | Planning authority records | REPORTED |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Experts in climate and adaptation policy ask how planning can keep pace with a changing climate.
Adaptation requires decisions now about assets and land uses that will last for decades, under a climate whose future depends on emissions and on uncertain system responses. Planning standards based on past climate may no longer hold. Approaches that keep options open, set signposts for when to change course, and favour measures that perform reasonably across many futures are increasingly used to manage this uncertainty.
Adaptation also has distributional consequences. Defences protect some places and not others; managed retreat affects communities and property rights; restrictions on land use carry costs for those who own it. Policies that integrate nature, such as protecting floodplains and wetlands, can deliver both adaptation and biodiversity benefits but require coordination across environment, planning and infrastructure portfolios.
Mapping sequences of decisions and triggers with decision analysis under uncertainty. It requires sustained monitoring to work.
Comparing adaptation plans and institutions with policy and institutional science. Plans are often recent and outcomes not yet observable.
Assessing who benefits and who bears costs. Data on vulnerability is often coarse.
Assessing effects of adaptation measures with causal inference. Benefits occur in future events, making evaluation hard.
