1 Implemented by Integrated Resource Management (Water / / Food Security / WEF ) in Asian Cities: 1 st Phase nd Phase

2 Implemented by 12 Partner Cities in 7 Countries Ulaanbaatar Weifang Rizhao Rajkot Nagpur Da Nang Santa Rosa Naga City Chiang Mai Korat Pekanbaru Tanjungpinang Mongolia China India Vietnam Philippines Thailand Indonesia

3 Implemented by Rationale Demand for fresh water, energy and food will rise between 40-50% by 2030 Security of supply in one sector is inextricably linked to security of supply in each of the other two sectors. Cities Cities consume over two-thirds of the world s energy and account for more than 70% of global CO2 emissions 90% of the world s urban areas are coastal, putting cities at high risk from the impacts of climate change (C ) More than 80% of annual global climate change adaptation costs arise in cities (World Bank 2010) Cities play a leadership role in driving global action to address climate change!

4 Implemented by by approach highlights: the interdependencies between water, energy and food security the synergies and competing uses of water, land and energyrelated resources. a fundamental shift, from a sectoral to a cross-sectoral, integrated approach the Nexus approach challenges existing structures, sector policies and procedures. The three "supply securities" water, energy and food to be protected and used in a balanced manner.

6 Implemented by by Water and energy interconnected and water are interlinked: For nearly all types of energy production (coal, geothermal, hydro, oil and gas, nuclear) huge amounts of water are required; On average 15% of the world s total water withdrawals are used for energy production; is the dominant cost factor in the provision of water and wastewater services (extracting and conveying water, treating water, distributing water, using water and collecting and treating wastewater); can account for up to 30% of total operating costs of water and waste water utilities.

9 Implemented by by Objective: Create resilient cities (economically, socially, ecologically, politically) through: Physical infrastructure (innovative technologies & standards) (hard-ware), semidecentralized, cross sectoral infrastructure projects (grounded): o to energy & water reuse, o to energy, reuse of water, nutrients o Replacement of old water pumps (energy gains) & reduction of water losses o Efficiency of buildings, energy savings, renewable energies Social infrastructure (soft ware): all inclusive cities, people-centered development ( leave nobody behind ), holistic/integrated planning/system, decentralization along subsidiarity principles, empowerment of cities as key drivers of development Within the framework: Circular (green) economy approach /job creation/capacity building (return/reuse/recycle/recover) 8
