  3. In my policy-making I need an indicator in money terms for losses in environment and resources, as a counterweight to the indicator for production, namely national income. If a theoretically sound indicator is not possible, then think up one that is rather less theoretically sound. A Former Indonesian Minister for Population and Environment, 1986 A concerted effort to enhance habitability of our planet is unlikely to succeed unless we know “where we are” and “where we want to go.” To answer these questions, we must first consider exactly what we include in the term “environment.” If we restrict our definition to overly simplified definitions, such as the amount of a specified pollutant in the air, we have very little difficulty in measuring the environment. However, as we broaden our definition to include all the physical components, or all the physical and biological, or all the physical, biological and cultural ones, environment becomes exponentially more difficult to describe. W.A. Thomas, 1972

  4. Environmental quality indices • Cost of Remediation • Environmental Elasticity • Environmental Diamond

  5. Cost of Remediation (COR)

  6. Definition and Concept • COR is the cost of moving the present state of environment to a more acceptable level based on a set of pre-determined standards • Three steps... • Assess existing environmental quality • Establish a set of environmental standards or targets • Estimate aggregated costs of achieving environmental standards or targets

  7. Advantages of COR • It is in monetary terms and can be an effective counterweight to traditional economic indicators such as GDP • Costs of remediation of different components of the environment can be added, subtracted freely and, thus, it partially avoids the weighting problem

  8. Targets • Air and Water • Pollutants:Five pollutants including COD, suspended solids and heavy metals (water); total suspended particulates (TSP) and sulfur (air) • Targets:90% reduction in water and air pollutant emissions (1990 levels) in 10 years

  9. Targets • Land: Three Components • Soil Erosion Control • Target: 70% of eroded area will be controlled to achieve 70-95% erosion reduction within 10 years, • Forest cover • Target: 20% of total land cover within 10 years, • Municipal Solid Waste Management • Target: All municipal wastes will be collected and disposed immediately

  10. Targets • Ecosystem/Biodiversity Conservation • Target: Protected areas as a % of total land area,10% • 10-year plan of building national parks and conservation areas (Indonesia, e.g.)

  11. Cost Assumptions • PRC cost data on air, water and land (soil erosion control and reforestation) pollution control are used and extrapolated to other countries. • WB’s cost estimates on solid waste management in developing countries and IUCN’s cost data for Indonesia on ecosystem management (of parks and conservation areas) are used and extrapolated to other countries.

  15. Environmental Elasticity (EE)

  16. Definition and Concept • EE is a ratio : • aggregate percent change in environment / aggregate percent change in economy • Principal merits: • dynamic; uses data for two points in time to capture environmental changes w.r.t economic trends • it is a trend indicator as opposed to a state indicator

  27. II: SOCIAL DEVELOPMENT INDICATORS

  28. Social Development Elasticity (SDE) • SDE is a ratio : • percent change in ratios of income distribution / aggregate percent change in economy • Principal merits: • dynamic; uses data for two points in time to capture social changes w.r.t economic trends • it is a trend indicator as opposed to a state indicator

  31. a) Human Development Index(HDI) • Summary measure of three basic dimensions of human development: a. Longevity as measured by life expectancy at birth b. Knowledgeas measured by adult literacy rate(2/3) and combined primary, secondary & tertiary gross enrollment ratio(1/3) c. Standard of living (gdp /capita in US$) • Measuring HDI a. Fix goalposts for max and min value for each b. Calculate three indices (life expectancy, knowledge and GDP) and add them.

  32. Goalposts for calculating HDI**UNDP(2005): Human Development Report

  33. Calculating HDI 1.Calculating life expectancy index (D1) D1 =(actual value-min. value)/(max. value-min value); 2.Calculating knowledge index (D2) D2= 2/3 adult literacy index+ 1/3 gross enrollment index 3. Calculating GDP index (D3) D3 = (log actual value –log min. value)/ (log max. value – log. Min. value) 4. HDI = 1/3 (D1+D2+D3)

  34. Most and least livable countries -High HDI(>0.8) Iceland (0.968),Norway,Canada,Australia, Ireland - Low HDI(<0.5) Chad(0.389), Ethiopia, Mali, Guinea, Uganda

  35. Summary & Conclusions • Indicators of SD are many; like an automobile dashboard they serve many purposes. • COR indicate the amount of wealth a society has to forgo to realize environmental goals • EE expresses dynamic relationship between GDP growth and environmental degradation • ED reveals the state of the environment at a given point of time • SDE expresses dynamic relationship between GDP growth & income gap between the rich & the poor • HDI determines human well-being by measuring their longevity, knowledge and income.
