        economic impact: Droughts cause severe damage to the economy because it halts productivity and destroys agriculture. Countries in SubSaharan Africa are more susceptible to the direct costs of droughts because they tend to rely more on rainfall for their economy. For example, Uganda lost 237 million USD annually due to droughts during the last decade
        
        Syria case study
        
        Up to 60% of the land in Syria experienced extreme drought between 2006-2010, leading to one of the most extreme crop failures in history. A city in Syria called Hassake even experienced up to 75% total crop failure. It led to food insecurity, population displacement, water insecurity, economic unrest, instability factors catalysed by the drought contributed to the civil war.
      - impact on place
        
        Crop failure
  - - - impact on people
        
        People living in the areas affected by the coastal flooding because they will be forced to leave their homes and will become climate migrants.
      - impact on place
        
        Coastal flooding will erode land and beaches and increase the salinisation of soils e.g in Tuvalu.
        Due to coastal flooding, some places such as tuvalu are in danger of being completely submerged.

        Can cause crop losses through anoxia and root diseases.
        Flooding associated with tropical cyclones can cause crop failure

        various issues
        
        Increases soil compaction
        
        Can cause crop losses through anoxia and root diseases.
        
        Flooding associated with tropical cyclones can cause crop failure
- - - - Impact on people
        
        Flood risks increase
        Number of people exposed annually to a 20th-century 100-year flood is projected to be three times greater for very high emissions than very low emissions.
        
        Can affect agriculture as increased precipitation can lead to flooding and in turn the erosion of soil.
      - impact on place
        
        Causes soil to erode and lose nutrients
        
        Decrease in snowfall
        
        Drylands as it refills aquifers
  - - - Heat up atmosphere
- - - - As the ice melts, the sun is reflected mainly by soil and water which have a higher albedo than ice therefore absorb more heat
        So, melting of ice, → more heat absorbed by soil and water → temperature increase
- - - - In 2030, in North-East Brazil, wheat will decrease by 14%, in Central America the wheat will decrease by 9%
      - Fisheries impacted
        
        Will need to switch to more abundant fish species
