2 The Relevance of Water Energy Food Water 2010 Population Growth 2.5bn without access to modern 2of energy 1bn suffering from hunger 800mio without access to safe drinking water Consumption patterns 1.5bn without access to electricity 2.5bn without access to sanitation Economic growth + 40% energy demand % food demand Climate Change %-gap of water resources (between availability and demand) A radical transformation is needed (European Report on Development 2012) Seite 2

3 Water sector Water supply Sanitation and hygiene Wastewater Water resources Planning and Innovation Occurs Predominantly in Sector Silos Dams: flood prevention vs. energy generation more irrigation vs. water protection Energy sector Renewable energy Land use change leads to increased flood and drought risk Energy efficiency Water for electricity vs. water for irrigation Agriculture Agricultural production Post-harvest losses Access to market Land resources Water constraints for energy generation Access to energy Improved agriculture value chains vs. energy demand management Insufficient energy for drinking water and waste water land and water for energy vs. food crops Seite 3

4 GIZ - Nexus perspective in the water sector Global Regional Advisory GIZ provides services advisory to BMZ services and BMU for international for international agenda agenda setting, setting primarily to two Federal Ministries BMZ and BMU. e.g. by formulating the German position in the Post 2015 SDG discussion Support coordination between river basin organisations and regional energy Support actors supra-national and regional coordination e.g. between River Basin Organisations and Regional Water Actors National Advice to governments for considering interdependencies between water, energy and agriculture in planning processes e.g. assist government on for policy coherence and Nexus-framework-conditions. Local Large-scale implementation of innovative solutions e.g. agricultural water management, integrated water resources management in cities, solar-power desalination and irrigation. Seite 4

12 Example 2: Water and Wastewater Companies for Climate Mitigation (WaCCliM) ( ) Countries included in the WaCCliM-Program Km Seite 12

13 Water and Wastewater Companies for Climate Mitigation (WaCCliM) ( ) Objective: Reduce the carbon footprint of water and wastewater companies by reducing the energy consumption by integrating measures for greenhouse gas reduction into the operation of selected water and wastewater utilities in Mexico, Peru and Thailand improving political and institutional framework conditions for the use and financing of greenhouse gas reduction measures developing guidelines and information materials for improving the carbon footprint of water and wastewater utilities disseminating the experiences from Mexico, Peru and Thailand worldwide through the network of the International Water Association (IWA) GIZ Water Sector Projects Seite 13

15 How to approximate a water and a wastewater tariff? An example of a town with: 50,000 households or 125,000 inhabitants with piped water supply and a sewerage system Water Supply: Water production, treatment and distribution Groundwater abstraction, flocculation, filtration, desinfection, storage, distribution (1.250 km of network length) served households produced water distributed water metered water revenue water Investment cost Annual operation cost [ - ] [ m3/year ] [ m3/year ] [ m3/year ] [ tons/year ] [USD] [USD/year] (600 litres per household and day) (5% losses in the production process) (40% network losses) (according to meter reading results) (90% bill collection rate) (1.975 USD per subscriber) (0,1 USD per metered cubic meter) GIZ Water Sector Projects Seite 15
