Montane and watershed forests, situated on steep slopes, play a crucial role in maintaining water flow and preventing erosion. However, these forests suffered the highest deforestation rate among tropical forests in the 1980s. When forests are cut down, less moisture is released into the atmosphere, resulting in fewer rain clouds forming and a decline in rainfall. This leads to drought and degradation of the area. Madagascar, in particular, has been severely affected, with widespread deforestation transforming much of the island into a barren, red desert.Key points:Montane and watershed forests are vital for water flow and erosion prevention.These forests experienced high deforestation rates in the 1980s.Deforestation disrupts the water cycle, leading to reduced rainfall and drought.Madagascar has been severely impacted, with extensive deforestation causing widespread environmental degradation.
