Flooding is a significant and recurring disaster in Kogi State, Nigeria, which lies at the confluence of the Niger and Benue Rivers. This geographical location, coupled with the seasonal release of water from the Lagdo Dam in Cameroon, makes Kogi highly susceptible to severe flooding. With the frequency of floods increasing over the years, including major events in 1994, 2004, 2012, and more recently, in 2020, and again in October 2024, flood management has become a critical concern for the state.
In support of Kenya’s Blue Economy initiative, the Kenya Marine and Fisheries Research Institute (KMFRI) is developing a Marine Spatial Plan to drive marine and coastal sustainability and investment opportunities. The plan must simultaneously balance the human factor needs (marine-driven economies and livelihoods) with the sustainment and protection of Kenya’s important coastal and marine resources.
When the water supply to a large, bustling city such as Harare is threatened by decreasing oxygen levels, the use of technology - and specifically earth observation data - in order to map and predict concentrations of algal growth becomes critical. This was the approach used by Muongeni Manda, a Geoinformatics and Environmental Conservation postgraduate from Chinhoyi University of Technology, Zimbabwe.
Digital Earth Africa annonce le lancement de son service innovant de surveillance des masses d'eau. Ce service est le tout premier au monde développé sur - et pour - le continent africain.
Ce service est unique parmi les ensembles de données satellitaires sur les eaux de surface dans le monde, étant donné la nature d'accessibilité et d'opérationnalisation des données, et l'accent mis sur la fourniture d'informations opportunes, pertinentes et facilement interprétables aux décideurs.
Digital Earth Africa announces the launch of its innovative Waterbodies Monitoring Service. This service is a world-first developed in – and for – the African continent.
The service is unique among satellite-based global surface water datasets given the accessible and operational nature of the data, and the focus on providing timely, relevant and interpretable information to decision makers.
The South African Environmental Observation Network (SAEON) recently highlighted the power of Digital Earth Africa’s tools in the management and mitigation of South Africa’s coastal risks and hazards.
In an article entitled “Understanding Coastal Risk and Vulnerability in South Africa”, SAEON investigates the critical issues of coastal risk and vulnerability in South Africa, emphasising the importance of proactive monitoring and sustainable management practices.
Desertification and Drought Day, observed every year on 17 June, is led by the United Nations Convention to Combat Desertification (UNCCD) to promote international efforts of combating desertification and drought. Today we join the National Bureau of Statistics (NBS) Tanzania to share how Earth observation (EO) can be used to monitor the effects of drought.
Water management is vital to Africa’s future, but limited water data makes it challenging. Earth observation satellites collect vast amounts of data over Africa every day, some of which can be used to measure and monitor water. The Digital Earth Africa partnership organizes decades of satellite data – updated daily – into an analysis-ready ‘Open Data Cube’, and IWMI will work with them to develop tools to translate this data into decision-ready information for water resource management.
