1 Ecosystems Underpin Infrastructure in The NexusDamian Crilly
2 The Nexus 2050 Challenge 80% More Energy 9 Billion People 55% More 2050 – The ChallengeThe world population is predicted to grow from 7 billion in 2010 to 9.1 billion in 2050.Water: Demand projected to increase by 55% more than current levels by 2050 (OECD Environmental Outlook to 2050)Energy: Demand projected to increase by 80% more than current levels by 2050 (OECD Environmental Outlook to 2050)Food: Demand projected to increase by 60% more than current levels by 2050 (FAO:TOWARDS 2030/2050)As global populations continue to grow, development of innovative water infrastructure and technology that optimise and address the interdependencies of water, energy and food (i.e. multi-purpose reservoirs for agricultural irrigation, domestic water supply and hydropower) will become ever more important.This population increase will need to be serviced with water, energy and food against a backdrop of climate change.55%MoreWater60%MoreFood

8 Ecosystems are infrastructure – part of the “the stock of facilities, services and installations needed for the functioning of a society”Nature is part of the infrastructure portfolio of every country and every economyWater for foodWater purificationFlow regulationWater storageWater supplyWater storageCritical services from nature equate to functions of infrastructure. With the term infrastructure defined as ‘the stock of facilities, services and installations needed for the functioning of a society’, nature is part of infrastructure portfolio of every country and every economy. This is ‘natural infrastructure’, which complements, augments or replaces conventional built infrastructure like reservoirs, dams, levees and canals. The natural infrastructure provided by ecosystems is usually highly cost-effective, and its restoration can provide attractive returns on investment in social and economic terms.Water supplyWater conveyanceCultural servicesFisheries provisionWater for energy

WaterRecent estimates indicate that megacities lose more than 50% of their water through mismanagement and poor infrastructureFoodEach year 30% - 50% of global food production is wasted – with a water footprint of 550 billion cubic metres (approximately what China uses in year)EnergyIn 2010 Saudi Arabia’s desalination plants used 1.5 million barrels of oil per day – 1/6 of its outputSource: Wilson Center 2013

12 Available Natural Resources Flood regulationWater purificationWater provisionWater storageAvailable Natural ResourcesEcosystemFunctionWatersecurityEcosystems critical to the nexus. Services from ecosystems, natural infrastructure, underpin each of the three securities of water, food and energy. Without healthy ecosystems in well-functioning watersheds, the infrastructure built for irrigation, hydropower or municipal water supply does not function sustainably, and is unlikely to achieve the economic returns necessary to justify investments. With its functions integral to the three securities and their inter-dependence, nature is part of the infrastructure needed to manage the nexus and its resilience.Fisheries provisionWater for energy
13 I need to set up a multi-disciplinary, cross sectoral partnership The ProblemAlthough the need for integration is acknowledged, many of our institutions are divided into ‘silos’, separated by thematic and technical boundaries, principles and practice, often from the top down.Traditionally responsibility has been given to water agencies but the challenges are not all owned or controlled by water agencies.Most water institutions tend not to have the mandate or policies that are comprehensive or integrated enough to address these complex inter-related problems.Adapted from Global Integration
14 Integrated River Basin Management A better understanding of river basins as complex systems is needed.A focus on a systems approach would lead to more integrated resource management across the land-water-energy sectors in river basins.Nexus connectivity between land, water and energy provides a focal point to facilitate integration – vertical, horizontal and multi sectoralTop Down and Bottom UpBy focussing on the sphere of influence between sectors provides opportunities for collaboration and ultimately leading to partnership.Adapted from Grigg 2008
15 Natural infrastructure does not replace the need for built infrastructure and natural infrastructure can compliment built infrastructure. For example, dams benefit from forests that stabilize soils and hold back erosion upstream. Lakes and wetlands provide water storage and therefore reduce the reservoir volume needed and thus the cost of built water storage. Well-functioning natural infrastructure is necessary for built infrastructure to perform its functions better, to ensure projected benefits and to increase returns on investment.
