Project Fact Sheet

Integrated Resource Management in Asian Cities: The Urban Nexus

In the framework of this project up to ten selected cities in six Asian countries will be supported with a view to nexus-compliant integrated resource management. During the implementation period, the basis for an integrated resource management approach will be developed. The project focus is on the topics of secure water supply and sanitation systems, energy security and efficiency, land use, physical planning and food security. Moreover, an exchange of knowledge and experiences and the cooperation between public, private and civil-society stakeholders is essential.

On water security, sustainability, and the water-food-energy-climate nexus

The role of water security in sustainable development and in the nexus of water, food, energy and climate interactions is examined from the starting point of the definition of water security offered by Grey and Sadoff. Much about the notion of security has to do with the presumption of scarcity in the resources required to meet human needs. The treatment of scarcity in mainstream economics is in turn examined, therefore, in relation to how each of us as individuals reconciles means with ends, a procedure at the core of the idea of sustainable development. According to the Grey-Sadoff definition, attaining water security amounts to achieving basic, singlesector water development as a precursor of more general, self-sustaining, multi-sectoral development. This is consistent with the way in which water is treated as “first among equals”, i.e. privileged, in thinking about what is key in achieving security around the nexus of water, food, energy and climate. Cities, of course, are locations where demands for these multiple resource-energy flows are increasingly being generated. The paper discusses two important facets of security, i.e., diversity of access to resources and services (such as sanitation) and resilience in the behavior of coupled human-built-natural systems. Eight quasi-operational principles, by which to gauge nexus security with respect to city buildings and infrastructure, are developed.

Open for business or opening Pandora’s Box? A constructive critique of corporate engagement in water policy

The corporate world is waking to the realisation that improved water management is fundamental for future prosperity and human well-being. This special issue explores aspects of its response: from the application of an array of analytical tools such as water footprint accounting, risk filters and standards; water use efficiencies; derivatives and insurance mechanisms; to collaborative infrastructure and watershed projects; stakeholder engagement and attempts to influence water governance at all scales. Drawing on the papers in this issue the motivations for this new agenda are traced and its potential in helping to unlock some of our most intractable water challenges, or to open a Pandora’s box of controversies are considered. Key concerns include the potential for diverging corporate and public interests; policy and regulatory capture; privileging of economic over social perspectives; process inequities; displacement of existing water management priorities, and the risks of misguided interventions which undermine institutional and hydrological sustainability - with the financial support of Water Witness International, WWF, The Nature Conservancy (TNC) and German Technical Cooperation (GIZ)

New Drivers for Sustainable Urban Development - Key Messages on Green Urban Economy from Bonn to Rio

Three focal areas need to be addressed for a transition to a Green Urban Economy, which promotes environmental well-being and improved quality of living for all income groups (i.e. Green Jobs and Poverty Eradication; Financing and Green Investments; Effective Governance and Institutions). The messages and their conditions offer potential ways to address environmental and social concerns in an economically viable way at the local level.

The growth of the earth’s urban population and areas continues as a major demographic trend; it is projected that 70 % of the world’s population will live in urban areas by 2050. Urban growth today is most rapid in developing countries, where cities gain an average of 5 million residents each month.

Session at the ICLEI World Congress

The “nexus” of food, water and energy represents one of the biggest challenges in urban areas. If supplies of these three key resources are not maintained over time to serve human societies as well as the natural ecosystems from which they derive, the basis for all life will be undermined, and cities will not be functional any more.

“The world has entered a period of volatility and transition - every choice that is made from here on will have an impact on what will happen in the near future.

Jeremy Bentham, Shell: “Gearing up for the future”

The inefficient use of natural resources and energy continues, especially in developing countries where population growth is most significant. Developed countries are often very wasteful. The combined annual food waste from Europe and the United States alone, for example, could feed about 1.5 billion people, notes Jeremy Bentham, Shell Vice President for Global Business Environment.

But take a look at the gigantic egg-shaped structures that dominate New York City’s Newtown Creek wastewater treatment plant, and you’re looking at the key to a sustainable future.

Changing Direction towards a New Energy Future

As the world transitions to a more sustainable energy future, the right decisions need to be made now to ensure that transition is as smooth as possible. In this speech, Shell Chairman Jorma Ollila discusses the important role that natural gas can play as an affordable, flexible energy source. He calls on policymakers to take a market approach to regulating CO2 to ensure all mitigation measures will be used, starting with those that are lowest cost and fastest to implement. He also talks about research Shell is conducting to understand the complex interrelationship between energy, water and food, and how we can be more efficient in managing them. - Speech given by Jorma Ollila, Chairman, Royal Dutch Shell plc, at the International Energy Agency Governing Board at Ministerial Level, October 18, 2011
