Living Planet Report 2014

Natural capital is a key concept of the Living Planet Report. While it may be an economic metaphor, it encapsulates the idea that our economic prosperity and our well-being are reliant upon the resources ovided by a healthy planet. In a world where so many people live in poverty, it may appear as though protecting nature is a luxury. But it is quite the opposite. For many of the world’s poorest people, it is a lifeline. And we are all in this together. We all need food, fresh water and clean air – wherever in the world we live.

China’s Water-Energy Nexus Challenge

Access to water and energy and continuity of supply are two critical issues facing China today. With the population expected to reach 1.6 billion people by 2030, the increasing demand for water and energy will far exceed available resources. Even today, China struggles to provide enough clean, fresh water and energy for industry, agriculture and domestic users. Limited resources have driven China to devise large infrastructure projects, which will significantly change the flows of natural waterways. It is also looking at the Tibetan Plateau as a potential source of future water and energy supply. Encompassing the sources of many of the largest rivers in Asia, China has the power to play water hegemon in the region, raising concerns about water security for downstream riparian neighbours.

“The Energy-Water-Food Nexus: Insights for the Business Community”

Through a thorough review of 54 documents (vetted by government, industry, and NGO experts), this document, published by the U.S. Chamber of Commerce Foundation, identifies steps that companies can take to understand and address their connections to the E-W-F nexus. These steps include: 1) Understanding the interconnected nature of the nexus; 2) Surveying and Data Collecting to find a company’s total resource consumption, and from where the resources are consumed; 3) Assessing Risks and Opportunities to see how a corporation’s consumption of resources can impact business operations; 4) Implementing technologies and programs to mitigate nexus risks; 5) Collaborating with stakeholders to address shared risks; 6) Leading the charge to address nexus challenges through engaging the business community.

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)

Asian countries urged to plan for sustainable urbanization

Asia is the fastest-growing region in the world, with a billion people added to its cities from 1980 to 2010. Urbanization drives Asia’s position as an economic powerhouse, but for this growth to be sustainable, careful planning is being urged to create more resilient cities that are not only resource-efficient, but also promote quality of life. With the rapid pace of urbanization across the globe, the vital resources of energy, water and food are coming under great pressure. In 2014, Shell led the Powering Progress Together (PPT)-Asia forum in Manila, the first multisectoral dialogue in the region to discuss the relevant themes of the energy-water-food stress nexus.

Rethinking the Value of Wastewater

The world’s rapid transition to urbanization contributes greatly to the pressure on water, food security, and energy, as the World Water Week Workshop on Securing Water and Food in an Urbanising World explored. We cannot simply look at urbanization as an urban problem. As Pay Drechsel from the International Water Management Institute stressed in the seminar, urbanization has strong links to rural and peri-urban areas, as urban centers become sinks for both rural-borne water and nutrients. The informal sector around many rapidly developing cities, such as Chennai, has entered into a highly lucrative business pumping tanks and aquifers dry and selling the water to cities. The water is transported by trucks, adding energy costs to cities’ water supply. Through this system, informal water markets supply cities with every drop of water they can get, quickly drying up peri-urban areas. While it requires significant infrastructure costs to redirect water sources from increasing distances towards cities, peri-urban areas are suffering as cities squeeze them dry of water resources.

A survey of leaders at this year’s World Economic Forum in Davos revealed that, for the first time, water-related risks are among the top 5 concerns when considering the likelihood and impact of all major global risks.

The Role of Business in the Water-Food-Energy Nexus: Canadian Water Summit Comes to Calgary

The interconnectedness of energy, water and food has been the prime focus of international discussions this year. In March, the UN’s Food and Agriculture Organization (FAO) organized the 10th annual World Water Day, with the theme of Food and Water Nexus. Energy is a third and important component because to produce food, we need both water and energy. A connection can be easily drawn: to produce energy we need water, and to clean and deliver water for livelihood and food production, we need energy. Hence, we have the Water-Food-Energy Nexus.

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
