Environmental Impacts From outside:.increase of the sediment load (filling the rivers beds, permanently flooded areas). Deforestation and dams (changes in the flood pulse).increase in the input of agricultural chemicals, domestic and industrial wastewater (water bodies contamination).climatic changes
Environmental Impact Inside:.Conversion of original vegetation for exotic pastures.engineering Projects (dikes, roads, hydrovias, infra-structure).uncontrolled amount of fires.over fishing (?) esca (?)
