The Sustainable development Portal  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.

Selected article Africa's current poverty is rooted, in part, in its history. The transition from colonialism has been shaky and uncertain. Since mid-20th century the Cold War and increased corruption and despotism have contributed to Africa's poor economy. While China and India have grown rapidly and Latin America has experienced moderate growth, lifting millions above subsistence living, Africa has stagnated and even regressed in terms of foreign trade, investment, and per capita income. This poverty has widespread effects, including low life expectancy, violence, and instability, which in turn perpetuate the continent's poverty. Over the decades, attempts to improve the economy of Africa have met with little success.

Selected biography 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.
