Por Qué Estamos Aquí / Why We're Here

Arawave complementa el portafolio de GGGI en Paraguay

Arawave directly complements GGGI's Paraguay portfolio

CTAF — Proyecto Paraguay (2026): Paraguay fue seleccionado para un proyecto de demostración de IA + imágenes satelitales para mapas de riesgo climático (inundaciones/sequías). Nuestro pronóstico de precipitación por IA complementa directamente ese trabajo.

Paraguay selected for CTAF field demo: AI + satellite imagery for flood/drought risk maps. Our AI precipitation forecasting directly complements this.

Financiamiento para Agricultura Climáticamente Inteligente: GGGI + AFD estructuran líneas de crédito y un Bono de Resiliencia. Nuestros pronósticos de días secos informan decisiones de riesgo agrícola.

GGGI + AFD structuring credit lines + Resilience Bond for climate-smart agriculture. Our dry-day forecasts inform agricultural risk decisions.

Estrategia SLCP + Mercado de Carbono (MADES): GGGI ejecuta proyectos de GCF con MADES. La red de 60 estaciones ($400–700K) es un proyecto de adaptación financiable vía GCF.

GGGI executes GCF projects with MADES (SLCP strategy, carbon market). The 60-station network ($400–700K) is a fundable adaptation project via GCF.

El Desafío / The Challenge

Paraguay no tiene un sistema de pronóstico construido para sus condiciones

Paraguay has no forecasting system built for its conditions

Red de observación con brechas críticas: 97 estaciones EMA listadas, solo ~25 reportaron en 24h. 26 silentes >6 meses. El Chaco es la región menos servida.

97 EMA stations listed, only ~25 reported in 24h. 26 silent >6 months. The Chaco is the least served.

Ningún modelo global se valida para Paraguay. GFS, IFS, ERA5 — se ejecutan sin calibración. Nadie sabe dónde fallan o cómo mejorarlos.

No global model is validated for Paraguay. GFS, IFS, ERA5 — run without calibration.

Nosotros cambiamos eso. We changed that.

Lo Que Construimos / What We Built

Ensamble de pronóstico por IA, calibrado para Paraguay, con incertidumbre en cada número

AI forecast ensemble, calibrated for Paraguay, with uncertainty on every number

El Chaco — La Historia / The Chaco Story

El Chaco: menos observaciones, mayor vulnerabilidad, prioridad de adaptación para GGGI y MADES

The Chaco: fewest observations, highest vulnerability, adaptation priority for GGGI and MADES

Y es exactamente donde el modelo funciona mejor.

And it's exactly where the model works best.

El modelo compensa por la escasez de datos. El siguiente paso es instalar estaciones. Esa es la justificación para infraestructura financiable.

The model compensates for sparse data. Next step: deploy stations. That's the case for fundable infrastructure.

Lo Que Ofrecemos / What We Offer GGGI

All already built. Cost to GGGI: $0.

OfferRelevance to GGGI
Climate adaptation evidence Network gap documentation + validated skill data. Evidence for GGGI's GCF-funded adaptation work with MADES.
Heavy-rain probability AUC 0.884. For early warning and climate risk management — core adaptation work.
The Chaco story Model performs best in Paraguay's most climate-vulnerable region. Narrative ready for donor reports.
Fundable infrastructure case 60-station network ($400–700K) qualifies for GCF/GEF. Model demonstrates ROI.
Sovereign capability Built in Paraguay, Paraguayan data, public methodology. "National ownership" every donor requires.
Defensible methodology Every number has a CI. Reproducible. Survives technical review.

El Intercambio / The Exchange

Everything we offer costs $0 (already built). Everything GGGI offers is knowledge, access, and framing.

🤝 We give

  • Climate adaptation evidence (network gaps + skill)
  • Heavy-rain probability product
  • Chaco results for adaptation reporting
  • Fundable observation network case
  • Reproducible data with CIs
  • Sovereign capability narrative

🌍 GGGI gives

  • Climate finance pathway (GCF/GEF/KOICA)
  • Inclusion in GCF/GGGI evidence base
  • Letter of technical support / partnership
  • Introduction to GCF-accredited entities
  • Event platform (Climate Action Week)
  • Access to adaptation stakeholder network

Not asking for money. Asking for direction and access. GGGI knows which finance window fits a $400–700K network. That knowledge is worth months of research.

La Red de Observación / The Observation Network

The business case for adaptation finance

The problem: Paraguay needs ~60 automatic stations for WMO standards. No observations → no good forecasts → no effective adaptation.

ROI demonstration: AI model works best where stations are sparsest. Each new station improves forecasts via data assimilation. Demonstrable feedback loop.

ComponentCostNotes
AI model (already built)~$1202 months, full validation
Real-time operational pipeline~$1,500–3,000/yrWhen a pilot user commits
60-station observation network$400,000–700,000Adaptation infrastructure — fundable via GCF/GEF

GGGI structures the finance. We provide the technical case.

Lo Que Pedimos / What We Ask

Small, specific, time-boxed. One ask per conversation.

#AskWhy
1 Climate finance direction Which window (GCF/GEF/KOICA) fits a $400–700K observation network? Who's the right accredited entity?
2 Inclusion in GCF evidence Our network gap data and forecast skill are direct evidence for GGGI's GCF-funded adaptation work.
3 Letter of support / partnership A GGGI partnership opens doors with DMH, donors, and cooperatives we can't open alone.

Not asking GGGI to fund anything. Asking for the right path. They are the experts in structuring climate finance for Paraguay.

Estado Actual / Current Status

Already in conversations with relevant institutions

  • MADES / DNCC — Meeting confirmed
    Ing. Nora Páez (DNCC) + Adrian Valiente. Climate adaptation + early warning + Climate Action Week.
  • GGGI — Visit in progress
    We're here now.
  • IPTA — Engaged
    Lead engineer Orlando Knowlton → referred to MAG for climate/weather issues.
  • DMH — Pending
    Needs Decree 8701/2012 waiver for historical data. A GGGI or MADES letter would help enormously.
  • Itaipú Binacional — Contacts identified
    Hydrology division, 12 own EMA stations. Historical data for validation.
  • 4
    Observation Network — Horizon
    60 stations, $400–700K, fundable via GCF/GEF. Needs GGGI structuring + institutional backing.

El Próximo Paso / The Next Step

One specific conversation: How can Arawave complement GGGI's Paraguay portfolio — climate tech, climate-smart agriculture, or green finance for observation infrastructure?

¿Cómo puede Arawave encajar en el portafolio de adaptación de GGGI?
