Sustainable development has been defined as balancing the fulfillment of human needs with the protection of the natural environment so that these needs can be met not only in the present, but in the indefinite future. The term was used by the Brundtland Commission which coined what has become the most often-quoted definition of sustainable development as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."
The field of sustainable development can be conceptually divided into four general dimensions: social, economic, environmental and institutional. The first three dimensions address key principles of sustainability, while the final dimension addresses key institutional policy and capacity issues.
is the collection, transport
or disposal of waste
materials, usually ones produced by human activity, in an effort to reduce their effect on human health
or local aesthetics
or amenity. A subfocus in recent decades has been to reduce waste materials' effect on the natural world
and the environment
and to recover resources
from them. Waste management can involve solid
substances with different methods and fields of expertise for each.
Waste management practices differ for developed and developing nations, for urban and rural areas, and for residential, industrial, and commercial producers. Waste management for non-hazardous residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while management for non-hazardous commercial and industrial waste is usually the responsibility of the generator.
The waste hierarchy refers to the "3 Rs" reduce, reuse and recycle, which classify waste management strategies according to their desirability. It has remained the cornerstone of most waste minimisation strategies.
The Millennium Project
is an initiative that focuses on research implementing the organizational means, operational priorities, and financing structures necessary to achieve the Millennium Development Goals
or (MDGs). The goals are aimed at the reduction of poverty
, environmental degradation
, and discrimination
against women. At the United Nations Millennium Summit
in September 2000
world leaders initiated the development of MDGs and had set a completion date for the project of June 2005.
In order to support the MDGs, both UN Secretary-General Kofi Annan and Administrator of the UN Development Programme (UNDP), Mark Malloch Brown, have launched the Millennium Project to determine the best strategies for achieving the MDGs. The Project is headed by Professor Jeffrey Sachs. The Millennium Project worked from 2002-2005 to devise a recommended plan of implementation that will allow all developing countries to meet the MDGs and thereby substantially improve the human condition by 2015. The Millennium Project presented its final recommendations, "Investing in Development: A Practical Plan to Achieve the Millennium Development Goals," to the Secretary-General in January 2005. One highlight of the event was the group photo of the great majority of the then-current leaders of the U.N. member nations, taken by photographer Terry Deglau of Eastman Kodak.
Thomas Robert Malthus
– 29th December
) was an English demographer
and political economist
. He is best known for his highly influential views on population growth
. He was born to Daniel and Henrietta Malthus, the sixth of seven children. They were a prosperous family, his father being a personal friend of the philosopher David Hume
and an acquaintance of Jean-Jacques Rousseau
Malthus' views were largely developed in reaction to the optimistic views of his father and his associates, notably Rousseau. Malthus's essay was also in response to the views of the Marquis de Condorcet. In An Essay on the Principle of Population, first published in 1798, Malthus made the famous prediction that population would outrun food supply, leading to a decrease in food per person. He even went so far as to specifically predict that this must occur by the middle of the 19th century, a prediction which failed for several reasons, including his use of static analysis, taking recent trends and projecting them indefinitely into the future, which often fails for complex systems.
