The visuals present a comprehensive analysis of global water use divided by sector over a century and compare water consumption in Brazil and the Democratic Republic of Congo in the year 2000.
Overall, the data indicates a pronounced increase in water consumption across all sectors over the specified period, with agriculture being the predominant consumer. The contrasting statistics of Brazil and the Democratic Republic of Congo reveal significant disparities in water usage per capita and total consumption.
Examining the line graph, it is evident that agricultural water use experienced a dramatic escalation from approximately 500 km³ in 1900 to an impressive 3000 km³ by the year 2000. This sector significantly dwarfed both industrial and domestic water use, which were considerably lower throughout the period. Industrial water consumption exhibited a notable upward trend, rising steadily from 1900 to 1950 and then surging by over 1000 km³ in the subsequent half century, culminating at just above 1000 km³. Conversely, domestic water use displayed a more gradual increase, remaining below the 1000 km³ threshold throughout the entire timeframe.
In the table delineating water consumption in Brazil and the Democratic Republic of Congo, striking contrasts in figures are apparent. Brazil, with a population of 176 million, exhibited a staggering total water consumption of 26,500 km³, translating to a per capita usage of 359 m³. In contrast, the Democratic Republic of Congo, with a population of merely 5.2 million, displayed a total water consumption of just 100 km³, resulting in an exceedingly low per capita water usage of 8 m³. This discrepancy underscores Brazil’s prioritization of water for agricultural irrigation and domestic needs, further accentuating the pressing differences in water resources management and availability between the two nations.
