The availability of current land cover and land use (LCLU) information for monitoring the status of land resources has considerable value in ensuring sustainable land use planning and development. Similarly, the need to provide updated information on the extent of LCLU change in West Africa has become apparent, given the increasing demand for land...
State-of-the-art cloud computing platforms such as Google Earth Engine (GEE) enable regional-to-global land cover and land cover change mapping with machine learning algorithms. However, collection of high-quality training data, which is necessary for accurate land cover mapping, remains costly and labor-intensive. To address this need, we created...
Ghana has retained a substantial area of tropical forests in an extensive network of protected reserves. These forests are impacted by land uses such as logging, mining, and agriculture as well as wildfires. We studied forest disturbance and recovery from 2013 to 2020 using annual maps of forest cover derived from Landsat imagery. Fire-associated d...
The Upper Guinean Forest region of West Africa, a globally significant biodiversity hotspot, is among the driest and most human-impacted tropical ecosystems. We used Landsat to study forest degradation, loss, and recovery in the forest reserves of Ghana from 2003 to 2019. Annual canopy cover maps were generated using random forests and results were...
An increasing number of products and services based on satellite Earth Observation (EO) data are being developed for use by decision-makers in African agricultural contexts, providing information such as weather and climate forecasts, crop yields and water availability. Capacity development to support impactful use of EO data is a key component of...
Rapid population and economic growth quickly degrade and deplete forest resources in many developing countries, even within protected areas. Monitoring forest cover change is critical for assessing ecosystem changes and targeting conservation efforts. Yet the most biodiverse forests on the planet are also the most difficult to monitor remotely due...
The substantial variations in the anatomy, physiology and life-history trait of wetland plants tend to limit their ability to tolerate environmental stressors and can consequently affect their community composition and distribution. Comparative studies of wetland plants among water bodies of varying limnological characteristics are useful in unders...
Improvements in water, sanitation and hygiene (WASH) service provision are hampered by limited open data availability. This paper presents a data integration framework, collects the data and develops a material flow model, which aids data-based policy and infrastructure development for the WASH sector. This model provides a robust quantitative mapp...
We analyze amounts and spatial patterns of land cover and land use change (LCLUC) and particularly change to Built for four contiguous regions of southern Ghana between 2000 and 2010. Our objective is to understand the degree of urban expansion relative to urban densification during this time frame, to understand the relationship between population...
Land degradation and desertification have become complex environmental, social, and economic concerns in Ghana owing to decline in agricultural productivity, loss of biodiversity, and forced out-migration from degraded lands to cities in search of jobs or to rural forested communities for farming, resulting in further deforestation. In an attempt t...
Astrium GEO-Information Services partnered with the Forestry Commission of Ghana and the Centre for Remote Sensing and Geographic Information Services, University of Ghana (CERSGIS) to establish a forest monitoring capacity in Ghana. The project was funded jointly by GIZ and Astrium based on a public-private partnership agreement. The objectives of...
Production of development plans is vital for sustainable ecotourism development given the increasing competition for land to satisfy various human needs including agriculture, timber, and wood energy. Such human activities cause rapid destruction of wildlife habitat and loss of indigenous tree species. To enhance sustainable use of the flora and fa...
