SENTINEL-NORTH

National Command Center - Dark 3D War Room Map

Overview

The Missing Data Infrastructure in Africa’s Great Green Wall

Northern Nigeria’s battle against desertification has historically suffered from an information vacuum. Billions in multilateral funding were committed, yet monitoring relied on paper reports, delayed audits, and unverified claims. SENTINEL-NORTH was engineered as a sovereign digital infrastructure bridging ground-level tree survival with satellite-level federal governance.

Key Operational Metrics

3.4M+ Hectares Tracked

12,507 Active Edge Field Monitors (CEMs)

100% Offline Edge Capture Compliance

Multi-Tier Jurisdiction

Engineered for Four Connected Audiences

A connected sovereign ecosystem uniting ground fieldwork with ministerial decision rooms and international auditor requirements across complete administrative hierarchies.

Federal Leadership (Abuja)

Macro situational awareness, inter-state ranking, and transboundary corridor defense.

State PMUs (Kano, Katsina, Borno...)

Tactical fleet dispatch, nursery seedling logistics, and erosion triage.

Edge Field Monitors (CEM Corps)

Sunlight-readable, locked kiosk terminals for offline verification.

Multilateral Donors (World Bank / AfDB)

Cryptographic proof of survival and one-click ICR compliance audits.

Problem & Architecture

Solving the Sahel Reality

Proving technical and architectural rigor across extreme African operational conditions.

The Field Reality // 01

The "Ghost Tree" Fraud

Restoration projects often report millions of planted trees with no way to prove if they survived or even existed.

SENTINEL-NORTH Solution // 01

Hardware-Locked Cryptographic Proof

Every tree logged must carry a tamper-proof hardware GPS fix, AI canopy health verification, and an immutable local audit hash.

National Command: Tamper-Proof Audit Sheet (Proof of Survival Card)

The Field Reality // 02

Remote Sahel Connectivity Deadzones

Standard cloud apps fail where cell coverage is nonexistent, leading to abandoned digital systems.

SENTINEL-NORTH Solution // 02

Offline-First SQLite / Mesh Synchronization

Terminals operate 100% offline indefinitely. Data persists in encrypted local databases and uploads via community solar mesh hubs.

The Field Reality // 03

Bureaucratic Siloing

State teams work in spreadsheets; federal ministers rely on outdated quarterly PDFs; smallholders receive zero alerts.

SENTINEL-NORTH Solution // 03

Single Geospatial Truth Engine

An integrated PostGIS spatial backend feeding the Abuja War Room, State Workbenches, and SMS/USSD phones simultaneously.

Core UI Architecture

Module A: ACRE-Intel™ Rugged Edge Terminal

Dedicated Android Enterprise kiosk terminal operating in harsh daylight. Enables rapid 30-second observations with automated computer vision species diagnostics and offline persistence.

CEM Tablet Kiosk with real-time GPS watermark (12.8719° N, 7.2183° E).
Automated computer vision canopy assessment with circular survival ring (94%).

State Operations Dashboard - State PMU Workbench

Module B: State Operations Dashboard

Clean daylight-mode state PMU workbench for tactical fleet management, nursery seedling logistics, and state-level erosion triage across Northern state corridors.

State PMU Workbench showing active CEM Fleet Management Table and Nursery Logistics.
Real-time seedling dispatch and state-level survival monitoring.

Module C: Eco-Restore™ Planning Studio & Scenario CAD

Spatial decision-support environment for ecological planners. Models multi-spectral vegetation indices (NDVI), soil crusting degradation, and groundwater recharge prior to seedling dispatch.

High-resolution satellite orthomosaics with delineated parcel boundaries.
Gully erosion alerts and automated 5-year predictive hydrological modeling.

Module D: Impact-Tracker™ Sovereign Audit Ledger

Multilateral donor accountability layer. Maps capital disbursement directly to surviving physical biomass on the earth, producing one-click automated compliance dossiers.

World Bank funding Sankey diagrams connected to verified nursery batches.
Circular compliance gauges certifying 96.4% Cryptographic Proof of Survival.

Module E: Livelihood-Connect™ Community Resilience Bridge

Human-centered climate inclusion layer delivering hyper-local micro-climate forecasts, optimal cowpea planting windows, and fair grain market prices via SMS, USSD, and Hausa/Fulfulde voice IVR.

Farmer Mobile Web Dashboard alongside retro USSD terminal interface (*384*22#).
Two-way rural advisories operating seamlessly on 2G feature phones.

Impact

From Environmental Surveillance to National Digital Asset

"SENTINEL-NORTH establishes Nigeria’s first national environmental data asset. By transforming community fieldwork into verified digital telemetry, the infrastructure restores trust in climate finance, protects vulnerable pastoralist communities, and secures the ecological future of Northern Nigeria."
