Architecture des signaux d'adaptation au changement climatique

Le climat n'attend pas le rapport de crise.

Bangladesh, Maldives, Nepal, and Sri Lanka are among the most climate-exposed countries on the planet. They receive climate adaptation finance from the Green Climate Fund, bilateral donors, and national budgets. They run adaptation programmes across agriculture, coastal protection, early warning, and water security.

Not one of those programmes has a standing field-level evidence layer that detects deterioration before the crisis report is written. The cyclone arrives. The flood hits. The programme officer discovers three months later that an adaptation commitment was already failing before the event — from a report written after the damage. MetriqOne sees the drift the moment the field data moves. Three early warning layers, active simultaneously, before the crisis, not after the report.

Ce qu'aucun responsable de programme ne peut voir actuellement

L'adaptation est mesurée après la survenue des dommages. Un programme de protection côtière déjà fragilisé avant la tempête est qualifié d'échec climatique. Il s'agit d'un défaut de surveillance : la dégradation était invisible jusqu'à ce que la crise la révèle au grand jour.
La dérive saisonnière est silencieuse. Un programme de réduction des rendements qui enregistre une baisse de 2 % par cycle dans trois districts passe inaperçu dans le résumé trimestriel. Lorsqu'il figure dans le rapport annuel, deux saisons de culture sont déjà perdues.
Les gestionnaires de fonds vérifient après le décaissement. Le Fonds vert pour le climat (FVC) effectue les décaissements. Le donateur bilatéral verse la tranche. La vérification a lieu six mois plus tard, sur la base d'un rapport rédigé par le bénéficiaire. Si le programme était déjà en échec, les fonds sont perdus.
Il n'existe aucun système d'alerte précoce pour la mise en œuvre du programme. Il existe des systèmes d'alerte précoce pour les phénomènes météorologiques. En revanche, il n'existe pas de systèmes d'alerte précoce permettant de vérifier l'efficacité du programme d'adaptation lui-même. Ce sont deux problèmes totalement différents.

Trois niveaux. Actifs simultanément. Avant la crise.

MetriqOne does not predict the weather. It detects whether an adaptation programme is holding — continuously, from the field, with three early warning layers that fire at different speeds.

CPL — Premier

Counter Productive Level — a threshold the operator sets at deployment, active from day one. It fires weeks before the statistical layer can calculate anything. A programme officer sees a district drifting below the threshold they declared acceptable before the first observation was recorded.

Géométrie de la pente — Niveau global

The shape of the trend across multiple enrolled nodes. A single node may fluctuate; when the aggregate slope tilts, the pattern is structural. Visible at the programme level — not in any individual report.

XmR — Violation statistique

Natural Process Limits, calculated from the field data itself using Wheeler's method. When a reading crosses the XmR limit, the system is no longer within natural variation. Something has genuinely changed. The evidence is precise, dated, and falsifiable.

CPL fires first — weeks ahead. Slope geometry fires next — the aggregate picture tilts. XmR fires last — the statistical proof that the programme has genuinely shifted. Three layers, three speeds, all active simultaneously. No adaptation programme in South Asia currently has any of them.

Quelles conséquences pour le financement climatique ?

Délivrez-vous avec des preuves, non avec foi.

A GCF programme officer sees, before the next tranche is released, whether the previous disbursement is producing field-level results — or quietly deteriorating. The decision to release the next payment is backed by signal, not by a self-authored progress report.

Détecter la défaillance avant l'événement

An adaptation commitment that is drifting before the cyclone season is infinitely more actionable than one discovered to have failed after the damage. The CPL layer fires during the window when correction still works.

Comparer entre quatre pays

One convergence standard across Bangladesh, Maldives, Nepal, and Sri Lanka. A fund manager reading across all four sees one evidence layer, one threshold logic, one proof standard. Nothing to reconcile across national reporting formats.

Priorité au hors ligne là où c'est le plus important

Climate-exposed programme sites are, by definition, the places where connectivity fails first. Paper forms work from day one. The PWA submits when internet access returns. The evidence architecture does not depend on the infrastructure it is meant to protect.

Comment les preuves sont recueillies sur le Field

This page describes what the three early warning layers detect and why they matter for climate finance. The field workflow — how evidence is captured at each programme site, how cooperatives and communities are documented, how proof is printed and delivered offline — is a separate question with a concrete answer.

Comment fonctionne l'infrastructure Field →

Le climat évolue. Les programmes sont en cours. Le système d'alerte précoce n'est pas encore opérationnel.

The GCF is disbursing. Sri Lanka has a climate finance strategy through 2030. Bangladesh is running adaptation programmes across its most vulnerable districts. The Maldives just received $25 million for early warning. None of that finance comes with a standing field-level instrument that detects programme deterioration before the crisis report arrives. MetriqOne is that instrument — three layers, active simultaneously, built for the places where connectivity fails first.
