- "Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs" - Brundtland Commission definition of sustainability (most widely accepted definition)
-A United Nations commission responsible for creating the classic definition of sustainability- 1987 the World Commission on Environment and Development overseen by former Norwegian Prime Minister Gro Harlem Brundtland.
- Provided framework for coordinated action, proposing that all nations have a stake in fostering economic development (sustainable)
- Showed economic development, social equity, and environmental protection as inseparably related goals
- advanced public understanding of the link between poorer nations and global environmental protection
- poor countries must have the opportunity to develop economically because if they aren't then it will be much harder to convince all countries to support practices that can be sustained over time
- At the same time richer countries must foster policies to favor environmental conservation with economic development.
-Rooted in the limited and dated concept of sustainable yield which suggest that consumption must have limits in order to continue the generation of the yield without diminishing returns
-the Brundtland definition is concerned with intergenerational equity; that is, we have a 'stewardship' responsibility to assure future generations that we will not leave the world any 'deficits' in terms of overshooting the carrying capacity of the Earth's ecosystems (Pijawka 2012).
-Projected increases in Temperatures from 2020 to 2099
- projected increases in surface temperature based on the B1 (top) A1B (middle) A2 (Bottom) emission scenarios of the 4th IPCC assessment report
- Scenario based on highest amount of future emissions predicts an increase in temperatures between 2, 4 Celsius and 6.4 celsius

-Future Precipitation Patterns
- Anticipate future droughts, heavy rainfalls, and floods

Some effects of the changes in precipitation patterns in relation to urbanism and agriculture:

[Unlike temperature, which has increased almost everywhere on the planet, precipitation is increasing in some parts of the world and decreasing in others. The warmer the air becomes, the more water it can store and then release it during wet days. This can lead to storm floods and heavy damage in areas where the infrastructure is not able to handle the release of large amounts of water in short amounts of time.

In addition to the increases in frequency and magnitude of heavy rainfall, season changes of precipitation are occurring as well. Farmers are concerned that seasonal changes of rainfall will affect their growing and harvesting seasons (so it can be seen how these changes are also important to land ecosystems and the agricultural sector).]

- Differences in Sea Level Rise
- Ice sheets are shrinking and that this trend will continue
- sea level rise range from 18 to 59 centimeters by the end of the 21st century
- sea level rise will not be the same everywhere
- in some areas the sea level increase is around 20 centimeters higher than the global average
- sea level rise in the southern ocean is expected to be below average

- Water Security
