The Doce River Basin (Portuguese: Bacia do rio Doce) is located in the southeastern region of Brazil. According to the Doce River Basin Committee (CBH-Doce), it belongs to the Southeast Atlantic hydrographic region, has a drainage area of 86,175 square kilometers and covers all or part of 229 municipalities. 86% of the basin's area belongs to the state of Minas Gerais, in the Doce River Valley ...
The Doce River (Portuguese: Rio Doce [ˈʁi.u ˈdos(i)], "Sweet River") is a river in southeast Brazil with a length of 853 kilometres (530 mi). The river basin is economically important. In 2015, the collapse of a dam released highly contaminated water from mining into the river, causing an ecological disaster.
The Task Force is responsible for activities related to adaptation to climate change, including flood and drought management. In 2007–2009 they prepared a Guidance on Water and Adaptation to Climate Change [29] which provides recommendations for the governments. The Task Force implements the Guidance through various pilot projects and a ...
Water resources management is a key element of Brazil's strategy to promote sustainable growth and a more equitable and inclusive society. Brazil's achievements over the past 70 years have been closely linked to the development of hydraulic infrastructure for hydroelectric power generation and just recently to the development of irrigation infrastructure, especially in the Northeast region.
Global climate change will probably make it more complex and expensive to ensure water security. [50] It creates new threats and adaptation challenges. [51] This is because climate change leads to increased hydrological variability and extremes. Climate change has many impacts on the water cycle.
Contaminated water discharges into the sea through the Doce River after the Mariana dam disaster. Brazilian marine ecosystems are under pressure from industrial fishing, navigation, port and land pollution, coastal development, mining, oil and gas extraction, invasive species and climate change.

Brazil's rainforests, and the Amazon, are particularly at risk to climate change. At worst, large areas of the Amazon River basin could turn into savannah, with severe consequences for global climate and local livelihoods. [3] Sea levels in Brazil are predicted to rise by more than 20cm by the middle of the century. [4]
The environmental impact of reservoirs comes under ever-increasing scrutiny as the global demand for water and energy increases and the number and size of reservoirs increases. Dams and reservoirs can be used to supply drinking water , generate hydroelectric power , increase the water supply for irrigation , provide recreational opportunities ...
