Open Access and Closed Minds:Balancing Intellectual Property and Public Interest in the Digital Age

Communicating for social change is an incremental process. Despite television being the world's most pervasive medium, broadcasts alone cannot accomplish this. Our experience in developing Asia shows that narrowcast outreach in classrooms and other small groups is often more effective. However, clearing non-broadcast rights is a major struggle.

The Radical Middle: Building Bridges Between the Muslim and Western Worlds

The long list of incidents that have revealed the intensifying tension between the Muslim and Western worlds over the past few years is countless. The terrorist attacks of 9/11, the wars on Iraq and Afghanistan, and the interminable conflict between Israelis and Palestinians are merely the highest profile examples of a global state of affairs whose ramifications extend to even the very local and regional levels.

Ombudspersons for Future Generations: Bringing Intergenerational Justice into the Heart of Policymaking

As the philosopher Edmund Burke wrote: [Society is] a partnership not only between those who are living, but between those who are living, those who are dead, and those who are to be born. Society is not, as it has become, a game of political horse-trading between the ruling party and the opposition which tries to court capricious swing voters.

The Link Between Disarmament and Sustainable Development

Twenty years after the 1992 landmark Earth Summit, the world is getting prepared for another conference of the same magnitude, hopefully with increased positive results. Building on commitments adopted by the international community over the last two decades, the United Nations Conference on Environment and Development -- Rio+20 --should pave the way for the launch of a reinvigorated sustainable development agenda -- one that takes into account the complex nature of the root causes of poverty which lie at the core of the devastating effects of environmental degradation, as well as the cross-cutting nature of this issue that it is embedded in almost every economic and social activity of mankind.

Working Towards a Sustainable UN

Sustainable development is a core objective for the United Nations family. Through their many and varied activities, all UN organizations contribute to sustainable development in one way or another—through economic development, poverty alleviation, healthcare, peacebuilding, infrastructure support, or environmental protection.

Health and Food Security: Benefits from Climate Change Mitigation

Societies must find a way to stop the rapid growth in carbon dioxide (CO2) emissions to avoid a disastrous future for our planet. As the greatest contributor to global warming, CO2 is the natural focus of current climate negotiations. Unfortunately, one of the very properties that makes CO2 so problematic—the long time it stays in the atmosphere—creates high barriers to efforts aimed at reducing its emissions.

Involving the Forgotten: Widows and Global Sustainable Development

Four years ago, the UN Chronicle offered me a forum to propose, and give reasons for, the proclamation of an annual International Widows' Day. That idea has become reality with the United Nations General Assembly declaring 23 June as International Widows' Day.

Managing the Water-Land-Energy Nexus for Sustainable Development

We live in the Anthropocene in which humans have become a major force shaping the environment. Rising incomes and reduced poverty have coincided with the growing demand for goods and services, such as food and energy, which in turn has increased the pressure on natural resources and ecosystems leading to their over-exploitation and degradation. Climate change adds to this predicament, as several climate adaptation and mitigation measures such as irrigation, desalination, or biofuels, are also resource intensive.

Managing the Risks of Extreme Events and Disasters

The Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC), which was completed in 2007 stated that: Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.

Vulnerable Countries Should Take Centre Stage at Rio+20

The overarching question is: what can the world 's Least Developed Countries (LDCs), Landlocked Developing Countries (LLDCs) and Small Island Developing States (SIDS) expect from the historic gathering in Rio de Janeiro this June?

Gender Equality and Sustainable Development

Women are making their voices heard and are fighting to ensure that Rio+20 marks real progress for all people. A successful Rio+20 will enhance women's rights and their access to and control over resources and decision making spheres.

Why Water Management Starts at the Local Level

Water is ubiquitous: it is essential for all forms of life and virtually all economic activities. The United Nations has declared that a human right exists for reliable access to safe and clean drinking water and sanitation which, along with other domestic purposes, accounts for about 7 to 10 per cent of all water use.

Feeding the World Sustainably

Approximately 925 million people are suffering from hunger. We cannot call development sustainable if one out of every seven persons is left behind. At the same time there is hunger, which is senseless in a world that already produces enough food to feed everyone. Hundreds of millions more suffer from obesity and related medical problems.

Addressing the Sustainable Urbanization Challenge

The cities of the world's emerging economies are increasingly drivers of global prosperity while the planet's resources are fast depleting. It is, therefore, more critical than ever that Member States and United Nations agencies commit themselves to realize the goal of sustainable urbanization as a key lever for development.

Objectives and Vision for Rio+20

In June of this year, world leaders will gather for Rio+20 with the objective of securing renewed political commitment for sustainable development, assessing progress and remaining gaps in implementation, and addressing new and emerging challenges.
