Future trends in waste quantities in low-income cities World population Urbanisation – Waste per capita Factor 1 Factor 2 Factor 3 growth megacities increase with development (2030: 40 megacities – 32 (GNI, GDP, HDI, in Global South) etc.) Source: United Nations, Department of Economic and Source: United Nations, Department of Economic and Social Social Affairs, Population Division (2011): World Affairs, Population Division: World Urbanization Prospects, the Population Prospects: The 2010 Revision. 2011 and 2014 Revisions.

Wasteaware: Physical indicators: an example Coverage: both physical No. Category Indicator Results and governance aspects 1 Collection coverage 82% Indicators comprise: 4 Public health – quantitative + 8 Quality of waste Waste collection 1Q M/H collection service composite qualitative 2 Controlled disposal 0% Global applicability: Environmental control – waste both ‘South’ & ‘North’ Environmental quality of treatment and 2Q waste treatment and L/M disposal disposal Visualise relative performance: using 3 Recycling rate < 5% 3Rs – reduce, ‘Traffic lights’ system reuse and recycling 3Q Quality of 3Rs provision L/M Ready to use: tested in 50 cities in all 6 inhabited continents

New standardised MFA for cities covering informal recycling sector CVORR project: Complex Value Optimisation for Resource Recovery

Acceptability – application to date • Comprehensive benchmarking system • Standardised methodology • World-wide coverage: accommodates for low income country realities • Awards: Academic paper wins 2015 ISWA Publication Award and CIWM 2014-15 James Jackson Medal for major contributions to solid waste management. • Adopted by: Data in UNEP/ ISWA Global Waste Management Outlook

Adopted by Population Reference Bureau: World Population Data Sheet

Wasteaware: benchmark cites indicators: Web-portal about to be launched
