1. Resources and Development
SUSTAINABLE DEVELOPMENT

2. SUSTAINABLE DEVELOPMENT : Introduction
A country that uses its resources in the best way is said to be developed.The
resources we have can be natural or man-made.We use natural resources like
minerals and metals to build man-made resources such as machines.The use of
Natural Resources usually goes unchecked.Therefore many times we may
overuse them.Too much water drawn from the ground,too many trees cut
down,too much coal extracted and burnt,etc is depleting resources.Depleting
resources are a cause for concern.

3. We need to develop ways to use the resources in a way that will allow us to
benefit as well as the future to use them.This method of utilising resources
carefully for development is called Sustainable Development.
Sustainable Development means economic development that meets needs of
present without compromising needs of future.It requires coordinated
economic ,social and environmental efforts to develop sustainably.A sustainably
developed society is a balanced economy,with a healthy society and blooming
environment.

6. Best Practices in Sustainability
While the vast majority of US companies are asleep at the wheel when it comes to facing up to
multiple sustainability challenges, a select group is waking up to the need for urgent action.
The following Companies have made attempts towards sustainability:
Water stewardship: Coca-Cola
The drinks company has improved the efficiency of its water use by 20% and identified the
need for a rigorous third-party evaluation of its water management approach.
Supply chain management: Ford Motor Company
The car company has established requirements for first-tier suppliers to drive its environmental
and social expectations further down the supply chain and works with suppliers to establish
GHG emission reduction and energy efficiency targets.

7. Design: Dell
The computer company's integrates alternative, recycled and recyclable materials in its product
and packaging design, improvements in energy efficiency, and design for end-of-life and
recyclability. One of the company's commitments is to reduce the energy intensity of its product
portfolio by 80% by 2020.
Greenhouse gas emission reductions: Adobe
The software company aims to achieve a 75% reduction, from 2000 levels, in company
emissions by 2015. It is using renewable energy technologies, including hydrogen fuel cells and
solar arrays, and is also focused on reducing energy needs by improving the cooling efficiency
of its data centers and "virtualizing" many of its systems, platforms and devices.
Since 2017, Adobe has decreased its total energy consumption by over 10,000 MWh and
decreased GHG emissions by 1000 tonnes. They're on track with their commitment to achieve
100 percent renewable energy by 2035.

8. Features/Advantages of sustainable development
include:
● A sustained rise in per capita income (PCI) worldwide
● Rational usage of resources
● Pollutional checks
● Population control
● Relative dependence on renewable sources of energy to meet future
generation’s needs

9. Disadvantages of Sustainable Development are:
● Increased Costs
● Lower Quality of Life for Some Elements of the Society
● Resistance to New Methods:Example:To get more electricity,industrialists may
want more dams.But this may submerge the land and disrupt the lives of people
who are displaced - such as tribals.
● Increased Regulation
● Political Struggle
