Overall risks from climate-related impacts are evaluated based on the interaction of climate-related hazards (including hazardous events and trends) with the vulnerability of communities (susceptibility to harm and lack of capacity to adapt), and exposure of human and natural systems. Changes in both the climate system and socioeconomic processes -including adaptation and mitigation actions- are drivers of hazards, exposure, and vulnerability (IPCC Fifth Assessment Report, 2014).
This section provides a summary of key natural hazards and their associated socioeconomic impacts in a given country. And it allows quick evaluation of most vulnerable areas through the spatial comparison of natural hazard data with development data, thereby identifying exposed livelihoods and natural systems.
The charts provide overview of the most frequent natural disaster in a given country and understand the impacts of those disasters on human populations.
Climate change is now recognized to have a significant impact on disaster management efforts and pose a significant threat to the efforts to meet the growing needs of the most vulnerable populations. The demands of disaster risk management are such that concise, clear, and reliable information is crucial. The information presented here offers insight into the frequency, impact and occurrence of natural hazards. Source (PDF)
Understanding natural hazard occurrence as well as historical climate conditions, in relation to development contexts, is critical to understanding a country’s historical vulnerability. This tool allows the visualization of different natural hazards or historical climate conditions with socio-economic and development datasets. Select the Development Context and either a Natural Hazard or Climate Condition and overlay horizontally by sliding the toggle left or right to gain a broader sense of historically vulnerable areas.
Data presented under Historical Climate Conditions are reanalysis products derived from ERA5-Land data. ERA5-Land is a global land-surface dataset at 9 km resolution, consistent with atmospheric data from the ERA5 reanalysis from 1950 onward. Climate reanalyses combine past observations with models to generate consistent time series of multiple climate variables. They provide a comprehensive description of the observed climate as it has evolved during recent decades, on 3D grids at sub-daily intervals.
This data has been collected, aggregated and processed by the Climate Resilience Cluster of the European Space Agency’s (ESA) Earth Observation for Sustainable Development (EO4SD) initiative.
- Floods are a recurring natural disaster in Guinea that can impact many different aspects of the socioeconomic landscape. Poor sewage and water systems as well as sanitation facilities are frequently affected by flooding, leading to inadequate disposal of human waste and contributing to the transmission of diseases such as cholera, typhoid fever, malaria, and/or polio.
- Sea level rise has been occurring along Guinea’s coast and will cause increased salinization and flooding in coastal regions, impacting agriculture, shortage in drinking water, destroying infrastructure, destruction of mangrove ecosystems, and proliferation of diseases.
- Drought is expected to be the highest climate risk for Guinea.
- Disturbance in rainfall, particularly the decrease in rainfall over Guinea, has led to the disruption of income, interruption of the agricultural calendar, and the disturbance of river regimes.
- Sea level rise will contribute to an increase in inundation in the coastal regions of Guinea. Increased flooding, especially in coastal zones and in northern Guinea pose threats to loss of human life and property, proliferation of waterborne diseases, soil erosion, destruction of crops, and decreases in agricultural production threatening the main economic activity of Guinean’s and food security of the nation.
- Streamflow in rivers have been negatively affected by episodes of droughts between 1961 and 1990. Further, droughts are projected to contribute to loss of biodiversity, reduce streamflow in major rivers, degrade headwaters, increase the proliferation of diseases and plant pests, increase water scarcity, and contribute to more bushfires.
- Disturbance in rainfall have serious implications on the main economic activity of 80% of Guineans as well as agricultural production and food security. Additionally, water scarcity is another implication of reduced streamflow.
- Improved water management, early warning systems, and saltwater tolerant crop varieties will help reduce risks in Guinea which are associated with sea level rise.
- Drought is expected to be the highest climate risk for Guinea. Improved water management systems and early warning systems will help alleviate water shortage risks and help the population prepare for these extreme events.
- Disturbance in rainfall, particularly the decrease in rainfall over Guinea, has led to the disruption of income, interruption of the agricultural calendar, and the disturbance of river regimes. Improved technologies in agricultural, improved water management, introduction of new crop species, and more will be important in decreasing the populations vulnerability to rainfall disturbance.
