Roots are a long term and stable carbon sink, accounting for about 0.4 of the above ground biomass across biogeographical regions. Well established and developed root systems provide various ecosystem services related to improved soil quality (higher cation exchange capacity and nutrient turnaround) and characteristics (improved soil porosity and aeration). Spatially explicit data and assessments of forest biomass and carbon are paramount to design and implement effective sustainable forest management options and forest related policies. The belowground biomass carbon index (BBCI) presented in

The CO2 fixed by photosynthesis is one of the most important components of the carbon cycle. Forests play a key role in this process. They represent large and persistent carbon sinks. Tree carbon stocks are important to quantify terrestrial carbon storage and carbon sinks, and to estimate potential emissions from land cover changes (deforestation, reforestation, afforestation) and from biotic (pests, diseases) and abiotic (forest fires, windstorms) disturbances. Spatially explicit data and assessments of forest biomass and carbon are thus paramount to design and implement effective sustainable

Chlorophyll-a concentrations (Chla) are an indicator of phytoplankton abundance and biomass in open waters. They can be an effective measure of trophic status and are commonly used to measure water quality. This layer compares the Chla value from the last full month with the long-term mean Chla. A positive anomaly (warm colours) means the monthly Chla is higher than the long-term average for that month; a negative anomaly (cool colours) means it is lower than the average.

The world is shrinking. Cheap flights, large scale commercial shipping and expanding road networks all mean that we are better connected to everywhere else than ever before. Accessibility - whether it is to markets, schools, hospitals or water - is a precondition for the satisfaction of almost any economic need. The new map of Travel Time to Major Cities -developed by the European Commission and the World Bank- captures this connectivity and the concentration of economic activity. It also highlights that there is little wilderness left. The map shows the travel time (in hours/days) to major

The Fire Information for Resource Management System (FIRMS) of the National Aeronautics and Space Administration (NASA) uses satellite observations to detect active fires and thermal anomalies. They deliver this information to decision makers in near real-time (within 3 hours of satellite observation). This dataset includes active fires of the last 24h. Each point represents the centre of a 375 m resolution pixel where a fire was detected. It is updated twice daily. Compared to other coarser resolution (≥1km) satellite fire detection products, it provides improved response for smaller fires

Substantial crop losses occur at various stages along the postharvest value chain. Losses result from poor handling and storage practices combined with limited awareness, infrastructure, and knowledge. The African Postharvest Losses Information System (APHLIS) (www.aphlis.net) is the foremost international effort to collect, analyse and disseminate data on postharvest losses of cereal grains in sub-Saharan Africa. The cumulative % loss in weight incurred during harvesting, drying, threshing/shelling, winnowing, household-level storage, transport and market-level storage for the selected crop

Monitoring of sea surface temperature (SST) provides fundamental information on the global climate system and for the study of marine ecosystems. For example, it helps estimating heat stress conducive to coral bleaching, the process by which they expel the symbiotic algae living in their tissues and become white (bleached) and vulnerable. The NOAA Coral Reef Watch's daily global 5km 7-day SST Trend product shows the SST trend for the most recent seven days. Pixels coloured in blue to purple follow a cooling trend while pixels coloured in yellow to red follow a warming trend. Pixels coloured in

Monitoring of sea surface temperature (SST) provides fundamental information on the global climate system and for the study of marine ecosystems. For example, it helps estimating heat stress conducive to coral bleaching, the process by which they expel the symbiotic algae living in their tissues and become white (bleached) and vulnerable. The NOAA Coral Reef Watch's daily global 5km satellite SST Anomaly (SSTA) compares the daily SST value with the long-term mean SST. A positive anomaly (+1.0 °C or more, warm colours) means the daily SST is warmer than the long-term average for that day; a

In 2016, a total of 42 billion cubic meters of water was lost through evaporation in hydropower reservoirs in Africa. A huge amount compared to the 1.2 billion cubic meters lost from all the other fuel types combined. In the same period, hydropower accounted for 15% of Africa’s total energy production. The ratio of annual water loss (from a hydropower reservoir) versus energy production (of the associated hydropower plant) describes somehow the water efficiency of a hydropower site. The ratio varies from region to region and depend on the reservoir’s surface area and evaporation rate, and on

Freshwater, in sufficient quantity and quality, is essential for all aspects of life and fundamental to sustainable development. Yet water-related ecosystems are threatened by human activities (flow alteration; loss of connectivity; pollution; habitat degradation and loss; overexploitation of species). Tracking changes in water-related ecosystems enables decision makers to determine the extent of change over time, understand the threats and implement appropriate mitigation measures. The water transition map shows the total change in the annual extent of permanent and seasonal surface water

Freshwater, in sufficient quantity and quality, is essential for all aspects of life and fundamental to sustainable development. Yet water-related ecosystems are threatened by human activities (flow alteration; loss of connectivity; pollution; habitat degradation and loss; overexploitation of species). Tracking changes in water-related ecosystems enables decision makers to determine the extent of change over time, understand the threats and implement appropriate mitigation measures. Reservoirs are defined as artificial, human-made water bodies. The water transition in reservoir map shows the

Surface water affects many aspects of our world: the exchange of heat, gas and water vapour between the planet's surface and atmosphere. Water is the engine behind the distribution, movement and migration of Earth's plant and animal life and is just as essential for humans. It affects our capacity to grow crops and manage animal grazing lands, to run our industrial processes, to manufacture goods, it influences the movement of disease-vectors, toxins and pollutants, it generates energy directly (hydroelectric) and indirectly (thermoelectric), it is an essential part of our transport network

Understanding why and where humanitarian disasters are likely to occur is a fundamental step in saving lives and promoting sustainable development. The coping capacity dimension of the INFORM Risk Index (global risk assessment for humanitarian crises and disasters) measures the ability of a country to cope with disasters in terms of organized activities, infrastructure and governmental effort. In particular, the infrastructure category presented in this layer measures the lack of capacity for emergency response and recovery. The risk score ranges from 0-10, where 10 is the highest risk.

Understanding why and where humanitarian disasters are likely to occur is a fundamental step in saving lives and promoting sustainable development. The INFORM Risk Index is a global, open-source risk assessment for humanitarian crises and disasters. It can support decisions about prevention, preparedness and response. This layer shows is which class of risk each of the African countries fall, on the basis of the latest INFORM Risk Index. The risk score ranges from 0-10, where 10 is the highest risk. The risk levels are set as follows: LOW = risk score 3.5 and below; MEDIUM = risk score between
