For centuries, rural communities in the high plateaus of the Andes have utilized water from melting glaciers that typify this amazing mountain range. But the retreat of these glaciers is forcing the communities to reconsider their livelihoods and ways to adapt. From a wider perspective, the melting of glaciers is an iconic warning to the larger cities in the Andes that rely on glaciers for potable water.

On 10 December 2008, the United Nations led worldwide celebrations to commemorate the sixtieth anniversary of the Universal Declaration of Human Rights.

Poverty reduction is the greatest challenge facing humanity today. An ideological commitment to reduce or eradicate this phenomenon should be contemplated as part and parcel of social moral responsibility and shared human values across countries and generations. Failure to do so will have unprecedented repercussions on human development.

We live in an age of wonders. From nano-surgery to space stations, networking sites to solar cells, Internet start-ups to smart capital, the world is a more connected, attractive and safe place than was dreamed possible, even fifty years ago.

There has been too little progress towards the achievement of the Millennium Development Goals (MDGs). At present, 40 per cent of the world's population is living below the minimum sanitation threshold, two thirds of all illiterate people are women and over 65 per cent of the people affected by HIV/AIDS live in Africa.

Developing countries depend on national and global economic growth to achieve the Millennium Development Goals (MDGs) by 2015. In this regard, international trade is recognized as a powerful instrument to stimulate economic progress and alleviate poverty.

A new series in the UN Chronicle will highlight the major intellectual contributions and policy consequences of work undertaken by major researchers who worked with the United Nations system during their careers.

The Millennium Development Goals (MDGs) summarize the development targets agreed to at international conferences and world summits during the 1990s. At the end of the last century, world leaders distilled the key goals and targets in the Millennium Declaration adopted in September 2000.

It was the best news for decades, when in 2000 world leaders acknowledged that the most urgent matter at the dawn of the new century was to put an end to poverty, and that the world has the resources and the know-how to do so.

When the United Nations General Assembly adopted the Millennium Declaration in 2000, the goals and targets it set in the section on development ultimately became known as the Millennium Development Goals.
