Seeing what the
land remembers.

Ing. Dr. George Ashiagbor reads Ghana’s changing landscapes from orbit—turning satellite signals into evidence for forests, cocoa farms, wetlands, and policy.

THE RESEARCH THESIS
01

From pixel to policy

A landscape is never
just a picture.

Every pixel can hold a forest edge, a cocoa farm, a wetland under pressure, or a policy decision waiting to be made.

Dr. Ashiagbor’s practice joins orbital observation with ground truth: seeing change, testing what the sensor suggests, and translating evidence into action.

The four territories

One practice.
Four living systems.

Each territory has its own signal, method, and consequence. Together they form a long-term record of environmental change across Ghana.

FIELD / A

Forest intelligence

Detecting canopy loss and degradation through multi-temporal Landsat and Sentinel-2 evidence.

FIELD / B

Cocoa landscapes

Separating agroforestry from natural forest to support traceable, deforestation-free supply chains.

FIELD / C

Wetland signals

Using radar to reveal mangroves, lagoon change, and hydrology beneath persistent coastal cloud.

FIELD / D

Land & terrain

Modelling erosion, urban expansion, and land-use transitions to guide local decisions.

02 / DEFINING WORK

Forest 2020 Ghana

Teaching a satellite to tell cocoa from forest.

As Remote Sensing Technical Lead, Dr. Ashiagbor helped develop Ghana’s harmonised cocoa-landscape classification—turning complex mosaic landscapes into evidence that institutions can use.

Principles for
the long mission.

Core philosophies linking discipline, rigorous observation, and generational mentorship across the scientific journey.

The next generation will always surpass the previous one.
