Likewise, there will be exhibitions of the latest products and services in geospatial science and technology.

Session at the AfricaGIS 2021

There were various presentations regarding how different companies and entities utilised GIS technology. Mitrelli Geodata presented his company’s products concerning Africa’s rapid urbanisation. The presentation noted that the rapid urbanisation would lead to severe space pressure, leading to a massive increase in infrastructural needs. According to the presentation, one of the solutions lies in investment in geospatial solutions. 

ESRI Africa regional manager Matthew Prennels presented what ESRI does. He also discussed the future of GIS, including the Integrated Geospatial Information Network. This framework provides a basis and guides for developing, integrating and strengthening geospatial information management. ESRI also discussed its ArcGIS technology 

Furthermore, The Place presented on the global GIS market and Africa. According to their presentation, the global annual GEO market is worth USD 400 billion, and Africa only represents 3% of the worldwide GIS market. They aim to map the urban world in ultra-high resolution and make these maps more open, reliable and accessible to help improve lives, create economic opportunity, strengthen public services and better care for the environment.

The consortium has offered nine scholarships to nationals of Gabon, Cote d’Ivoire, Chad, and Cameroon. Six of the beneficiaries are awaiting their project defences. The consortium has trained about 60 persons on the use of GIS and remote sensing tools.

GMES West African consortium – CSE presented on “Sustainable Wetlands Management for Enhancing Food Security and Ecosystem Resilience in West Africa (GDZHAO)”. The objective is to improve knowledge on West African wetlands from rational and sustainable management contributing to food security and resilience of socio-ecosystems through the provision of EO data derived products and services. The programme leverages the Sentinel 1 and 2 Copernicus Open Access Hub. In capacity development, the CSE has fully implemented five modules in the Digital Learning Platform (DLP). The CSE presentation also noted that it set up a research network on priorities and valorisation of research on wetlands in West Africa. There are also eight sessions on setting up a GDZHAO Community of Practice, with one training session in each member country. Forty-Six people have already benefited from the training sessions. The presentation also reported supporting eight persons via academic scholarships.

Session at AfricaGIS 2021

The CSSTE Consortium presented on Multi-scale Flood Monitoring and Assessment Services for West Africa. The programme’s objective includes establishing an updatable flood event database and providing DMOs with timely information before, during and after flood events. Their project sites include 

  • District of Abidjan; 
  • Oueme Basin (Benin);
  • Ogun-Osun Basin (Nigeria);
  • Black Volta (Ghana); and
  • Volta Basin (Burkina Faso).

The presentation includes discussions and illustrations on the following projects.

  • Flood risk maps of the five riverine study sites in West Africa;
  • Flood forecast and early warning system

The CICOS Consortium’s presentation began with addressing the issues and challenges faced in the sub-region. Some of them include population growth, deforestation, low stakeholder involvement, etc. The presentation also demonstrates the Congo Basin’s biodiversity. The presentation subsequently discusses the effects of climate change on the Basin. Some of the effects include silting of riverbeds, flow deficits, and temperature increase. 

RCMRD’s presentation was based on the lessons it had learned, some of which include:

  • Supporting awareness creation to policy and Decision Makers with the products and services of EO Data has been improving on the areas of planning for sustainable development;
  • Working with the stakeholders, mainly with the end-users, is for mutual benefit and has been playing an integral role in the protection and conservation of the environment;
  • Geoportal development and availing the products and giving services are found to be among the best approaches to support the data demanding EO and GEO communities; and
  • Organising and using events like Open Days, GIS Day, Earth Day, and Environment Day can be used to disseminate information, data, and products and get feedback.

The ICPAC Consortium also presented on Monitoring natural resources and food security in the East African Region. Their objective was to promote sustainable long-term management of natural resources in the East Africa region by providing decision and policymakers with information and tools needed for the implementation of sustainable environmental policies at regional and national levels. The Consortium also discussed its data hubs and how it improves data collection.
