Research report funded by the Aubrey Barker Fund conducted by The Association des Jeunes Experts sur les Questions Foncières (AJEF), Cameroon.
The Aubrey Barker Fund awarded a grant of £1,000 to the Association des Jeunes Experts sur les Questions Foncières (AJEF), a civil society organisation (CSO) based in Cameroon, to organise a seminar in Yaoundé in August 2025.
The seminar brought together 30 selected researchers and practitioners, who gained practical and career-enhancing skills in agile land project management with the Rapid Planning Toolkit, as well as in powerful writing and professional communication. Full report can be downloaded below.
At the Aubrey Barker Fund, we remained committed to investing in people who will shape the future of land governance.

Publication of a Research Study funded by the Aubrey Barker Fund and conducted in Cameroon by Mr. Marcel Loyd MINKA
In August 2023, Mr. Marcel Loyd MINKA received 1200 £ (pounds) from ABF (Aubrey Barker Fund) to sponsor his research study on Participatory Mapping for Land Boundary Conflicts mitigation in Mbalmayo, Cameroon. Mr. Minka started this research study in June 2023 and due to lack of sufficient funding from June 2023 to July 2023, his research study did not move forward. But thanks to the funding received from ABF in August 2023, Mr. Minka was able to complete his research study in October 2023. The following year, Mr. Minka submitted a full research paper manuscript on this study, and this study was successfully published by the International Journal of Social Science and Human Research under their special issue of December 2024.
This study was published as a research paper under the title “Assessing the Contribution of Participatory Mapping Data Collection Methods in Detecting and Mitigating Land Boundary Conflicts on Farm Areas: A Methodological Framework”.

Mr. Minka is a Ph.D. Researcher at the Department of Animal, Nutrition and Food Sciences (DiANA) of the Faculty of Agricultural, Food and Environmental Sciences at the Università Cattolica del Sacro Cuore. His research focuses on “Mitigating land conflicts and securing farmers’ land rights through improved participatory mapping”. In 2022, Mr. Minka received a Ph.D. Scholarship from the ‘De Africa’ project, financed by the Italian Episcopal Conference’s Service for Charitable Interventions in the Third World at the Università Cattolica del Sacro Cuore, to pursue a Doctor of Philosophy in Agri-food System (Sustainable Agriculture through effective Land Tenure Security).
In the above research paper, Mr. Minka talks about the fact that Land conflicts are a significant and sensitive issue in Africa, and these land conflicts are a serious threat to agricultural productivity. In the abstract of his paper, Mr. Minka notes that now our days there exist several methods of land data collection which facilitates land conflict mitigation, and each of these methods are been explained in various papers. However, none of these papers have compared these methods to bring out their unique contribution as a means to assist practitioners in identifying land conflicts prone areas. His research is centered around the question: what is the distinctive contribution of each land data collection methods in identifying land conflict prone areas during participatory mapping? Using a case study of three villages in Mbalmayo (Cameroon), his research adopts an approach that combines farmland data from interviews, questionnaires, consultative meetings, field visits, demarcation of farm boundaries; recording of Ground Corner Points using Catalyst DA2, UAV flights, and participatory mapping. In his paper, Mr. Minka discuss the usefulness and limitation of each method, highlighting their unique contribution to the holistic understanding of the context of Mbalmayo and the mitigation of land conflicts. His study was conducted from June to October 2023. The results of his analysis shows that amongst the eight methods used to collect farmland data, six of these methods had a distinctive contribution that facilitated the mitigation process by precisely identifying the land boundary conflicts zones. The ideas provided by his paper can serve as guidelines for researchers and practitioners interested in mitigating land conflicts through participatory mapping approaches.

ABF awards Bursary to Ryan Benade of Namibia for Master's Research
ABF has awarded Ryan Theodore Benade a tuition and registration bursary to undertake his Master’s in Spatial Sciences at the Namibia University of Science and Technology under the supervision of Professor Oluibukun Gbenga Ajayi.
This award continues a chain of generational mentorship: Professor Ajayi, too, was an ABF bursary recipient during his PhD studies at the Federal University of Technology, Minna. This demonstrates the Fund’s commitment to sustaining professional networks and capacity building in land management. The continuity reflects ABF’s ethos of long-lasting impact through educational support and knowledge sharing across generations of surveyors and spatial scientists.

Namibia’s agricultural potential is constrained by soil degradation, uneven fertilizer application, and limited spatial soil data, which together impede sustainable crop production. Ryan’s project entitled “Mapping Soil Macronutrients Using Multi-Spectral Remote Sensing and Machine Learning” addresses these challenges by predicting the spatial distribution of Nitrogen (N), Phosphorus (P), and Potassium (K) across key farming regions in Namibia. The study will generate continuous surface maps of soil fertility, enabling targeted interventions and optimised land use by fusing ground-sampled nutrient measurements with high-resolution spectral information from Sentinel-2 and Landsat 8.
The ABF bursary will cover a significant portion of his tuition and registration fees, freeing Ryan to dedicate his attention to research activities, field sampling, and data analysis without financial constraints. The expected decision-support tools, like the nutrient distribution maps and predictive models, will empower Namibian farmers and land managers to implement variable-rate fertilisation, thus reducing input waste and minimising nutrient runoff in alignment with UN Sustainable Development Goals 2 (Zero Hunger), 9 (Industry, Innovation and Infrastructure), 12 (Responsible Consumption and Production), 13 (Climate Action), and 15 (Life on Land).

Development of an integrated automatic image registration scheme
Oluibukun Ajayi (pictured above) reports on his PhD project: The Aubrey Barker project grant was awarded for the successful completion of my project which is part of a doctorate degree in Surveying and Geoinformatics at the Federal University of Technology, Minna, Nigeria in May 2018. The title of the funded research is ‘Development of an integrated automatic image registration scheme’ and it is aimed at developing an integrated model for the automatic registration of overlapping images captured from a drone with a view to optimising the process of tting images to existing maps. The grant was spent on eld work which consisted of hiring of equipment, such as the DGPS receivers used for the establishment of Ground Control Points (GCPs) and the Check Points (CPs), hiring of the Phantom 4 drone used for the image data acquisition, hiring of a project vehicle, payment of site allowances for eld/research assistants, beaconing of GCPs and CPs and marking them with re ective materials. Three different methods of describing features were integrated with epipolar correlation in the development of an optimised automatic image registration scheme. The developed algorithms were implemented using JAVA scripts and tested using the drone images in two different registration campaigns. Degraded images with poor spatial resolution and a small size were used for the rst campaign while images with excellent resolution, but of large size, were used for the second campaign.

In the course of this research, a novel integrated automatic image registration algorithm based on epipolar correlation was developed which proved to be more robust (with respect to speed and accuracy) than the automatic image registration algorithms that are based on selected conventional feature descriptors. The novel registration algorithm integrates both the geometric and epipolar constraints which makes it more robust in terms of accuracy and speed (processing time). Finally, an automatic image registration software which contains a stereo comparator and a module for automatic camera calibration was developed for easy implementation of the developed algorithms. The developed registration scheme will be of particular interest to the military, cartographers, radiologists, digital photogrammetrists and remote sensing experts as a tool for educational, training and industrial applications
