NOT FOR ATTRIBUTION; FOR DISCUSSION PURPOSES ONLY
Environmental Health :Costs of Environmental Health DamageAnd Net Benefits of Priority Interventions A Contribution to the Country Environmental Analysis for the Philippines (Part 1) by Agustin L. Arcenas World Bank CEA Workshop, June 16-17, 2008
Environmental Health - Areas of Concern • Outdoor Air Pollution (OAP) • Indoor Air Pollution (IAP) • Water Pollution, Sanitation and Hygiene (WSH)
Basic Outline of the Study (for each area of concern) • The basic issues and state of the environment • Level of exposure to pollutants and, sanitation and hygiene problems in the Philippines • Morbidity Incidence • Economic cost of Morbidity • Mortality Incidence due to environment • Economic cost of mortality • Suggested policy interventions • Economic evaluation of policy interventions
How the study was done… • Calculate the proportion of total cases of illnesses that are attributable to pollution, sanitation and hygiene • Using WHO and Philippine data, determine the cost of treatment and foregone income from illnesses and premature deaths • Aggregate the economic costs and values from these calculations
Total Economic Costs of Environmental Health Problems Total: PhP 9 billion
The Economic Costs of Illnesses caused by Outdoor Air Pollution
Sources of PM emissions Source: Monitoring Report, 2004
What we know so far… • There has been a drop in PM emissions in Metro Manila since 2003 • The number of vehicles in the country is growing • Diesel contributes more to PM than gasoline • Main source of PM emissions in the country – 2 stroke-tricycles • The bulk of vehicles in the country are the tricycles followed by utility vehicles
Morbidity Cases - OAP Total: 119,080
Costs to Society of OAP-related Illnesses Total: PhP 1.9 billion
Costs to Households of Treatment - OAP, 2003 Total: PhP 896 million
Foregone Income due to OAP-related Illnesses Total: PhP 118 million
Cost of Premature Deaths due to OAP, 2003 Total: PhP 697 million
Potential Interventions to curb OAP • Inspection and maintenance (I/M) programs • Installation of pollution control devices • Rehabilitation of Current Traffic Management System • Investments in Additional Mass Transport System
The Economic Costs of Illnesses caused by Indoor Air Pollution

Morbidity Cases - IAP Total: 114,665
Costs to Society of IAP-related Illnesses Total: PhP 2.3 billion
Costs to Households of Treatment - IAP, 2003 Total: PhP 774 million
Foregone Income due to IAP-Illnesses, 2003 Total: PhP 82 million
Cost of Premature Deaths due to IAP, 2003 Total: PhP 1.4 billion
Potential Interventions to curb impacts of IAP • Promote improved household living environment (improved ventilation) • Promote use of “improved” stoves • Effect changes in cooking practices

The Economic Costs of Water Pollution, Sanitation and Hygiene Issues
Household Access to Improved Water Supply and Sanitation, 2003 (National)
Morbidity Cases - WSH Total: 488,425
Costs to Society of WSH-related Illnesses Total: PhP 4.9 billion
Costs to Households of Treatment - WSH, 2003 Total: PhP 3.0 Billion
Foregone Income due to Illnesses from WSH, 2003 Total: PhP 465 million
Costs of Premature Deaths due to WSH, 2003 Total: PhP 933 million
Potential Interventions to eliminate illnesses from WSH • Water Sanitation and Hygiene • Improved water supply and quality • Hygiene Promotion • Construction of Sanitation Facilities (i.e. Latrines)
