Just in time for Rio+20, this special double issue looks at the objectives and visions of this landmark conference, and includes essays on bringing star power to earth, on sustainable energy for all, and on the need for a positive negotiating vision.
Although the term food security was coined only 16 years ago, humanity has been striving against famine and hunger since ancient times. Agreement at the 1996 World Food Summit, based on the concept that food security exists when all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life, gave a new vision to efforts against hunger and malnutrition.
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?
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.
The international community is threatened by a global energy crisis, climate, and ecosystem changes due to global warming, as well as water and food contamination. The whole world faces tremendous challenges in closing the gap between projected energy demand and the supply of sustainable, carbon-free, affordable energy. Today, about 80 per cent of the world's total primary energy demand is met by fossil fuel which emits significant quantities of carbon dioxide (a greenhouse gas) into the atmosphere.
Historically, flooding has invoked and spurred an altogether different social and political imagination, in which seasonal inundations have been celebrated for their ecologically renewing and economically beneficial properties. The regular flooding by the silt-laden waters of the Nile, for example, has long been recognized for having sustained and enabled Egypt's ancient civilization of the Pharaohs.
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.
Energy powers human progress. From generating employment to creating economic competitiveness, from strengthening security to empowering women, energy is the great uniter. It cuts across all sectors and lies at the heart of all countries' core interests. Now, more than ever, the world needs to ensure that the benefits of modern energy are available to all and that energy is provided as cleanly and efficiently as possible.
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.
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.
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.
