The line chart illustrates the global water usage across three sectors: agriculture, industrial, and domestic. In addition, the table provides data on water needs specifically in Brazil and the Democratic Republic of Congo.
Overall, water usage from these three sectors has increased to varying extents over time. Notably, water consumption is significantly higher in Brazil compared to the Congo.
In 1900, approximately 500 km² of water was utilized for agricultural purposes, while water consumption in the industrial and domestic sectors was around one-fifth of that amount. By the year 2000, agricultural water usage surged dramatically to approximately 3000 km². Subsequently, industrial water consumption also rose to around 1200 km², and domestic water usage reached about 500 km².
In 2000, Brazil’s population was approximately 176 million, compared to 5.2 million in Congo. Water consumption per person in Brazil was 359 m³, which is significantly higher than Congo’s rate of only 8 m³. Furthermore, Brazil had around 26,500 km² of irrigated land, which is 265 times more than that of the Congo.
