The "Map of Conflicts Related to Environmental Injustice and Health in Brazil" is an online map of conflicts relating to environmental injustice and health in Brazil. The map is maintained by the National School of Public Health of Brazil, the Oswaldo Cruz Foundation , and Núcleo Ecologías, Epistemiologias e Promoção Emancipatória da Saude ...
Brazil has always been considered a country rich in water. However, Brazil's hydro-climatic regions and irrigation systems vary widely. In the South, frosty conditions in winter have limited irrigation mainly to summer flooding of lowlands for rice production. In the milder Southeast, irrigation in winter has made double-cropping possible.
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. [1] The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice.
Brazil's vast inland cerrado region was regarded as unfit for farming before the 1960s because the soil was too acidic and poor in nutrients, according to Norman Borlaug. However, from the 1960s, vast quantities of lime (pulverized chalk or limestone ) were poured on the soil to reduce acidity.
In 2022, greenhouse gas emissions from rice cultivation were estimated at 5.7 billion tonnes CO2eq, representing 1.2% of total emissions. [59] Within the agriculture sector, rice produces almost half the greenhouse gas emissions from croplands, [60] some 30% of agricultural methane emissions, and 11% of agricultural nitrous oxide emissions.

Predictions of climate change's effects on rice cultivation vary. Global rice yield has been projected to decrease by around 3.2% with each 1 °C increase in global average temperature [142] while another study predicts global rice cultivation will increase initially, plateauing at about 3 °C warming (2091–2100 relative to 1850–1900).

The state's sugar and alcohol sector has 25 plants and employs around 55,000 people. The regions of Umuarama, Paranavaí, Maringá and Jacarezinho concentrate production. Brazil is the largest world producer, with 672.8 million tons harvested in 2018. [72] [73] In cassava production, Brazil produced a total of 17.6 million tons in 2018. Paraná ...
There was concern that an unresolved water crisis may impact the 2016 Olympic Games. [18] In 2017, the rains remained extremely irregular in Minas Gerais, [19] Espírito Santo [20] and most parts of the regions Central-West and Northeast. This is the worst drought in Brazil in the last 100 years, according to the O Estado de S. Paulo in ...
