Sustainable Development

Sustainable Development is a pattern of resource use that aims to meet human needs while preserving the environment so that these needs can be met not only in the present, but also for generations to come. Sustainable development has been defined in many ways, but the most frequently quoted definition is from Our Common Future, also known as the Brundtland Report. According to this definition, “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

Sustainable Development

the economic development is sustainable then the present use of natural resources will not limit us from their use in the future. Thus, sustainable development tells us that development must be of a kind which can take care of our needs as well as the needs of future generations. That makes it a long-term concept.

How Can We Achieve Sustainable Development?

  • For development to be sustainable we must think of development not only for our community or village or country but for the world as a whole. To give an example, if factories emit smoke in North America, then that air pollution from North America affects air quality in Asia. Similarly, pesticides sprayed in Bangladesh could harm fish stocks off the coast of West Bengal.
  • Measures for sustainable development therefore focus on policies that must be adopted in the whole world. Some of these policies are implemented at the level of governments of individual countries while others require coordination at the international level.
  • Some examples of ways in which we can contribute to sustainable development are given below.
  • Resources- finding substitutes for non-renewable resources and using renewable resources judiciously. Solar energy, wind energy, hydropower, tidal energy and biofuels (like gobar gas) are being widely and increasingly used as substitutes for energy sources like coal, oil and natural gas that are being depleted rapidly. In many villages of India, solar energy appliances like solar cookers, solar lanterns and solar heaters are being encouraged and promoted by the government. In coastal areas the wind energy harnessed by windmills is being used to generate electricity.
  • Recycling - to use again, to re-process. To make paper we need wood pulp which comes from trees. Therefore, by recycling used paper we can contribute to saving trees from being cutdown. Water is a scarce resource, yet we do not use water judiciously. We can reuse rainwater by rainwater harvesting.
  • Reduce - to use less or economize. Our consumption should be restrained to meeting our basic needs. We can walk instead of driving to the local market or climb using stairs instead of taking a lift, switch off fans and lights that we don՚t need.
