Why do we need Environmental & Natural Resource Accounts?: Why do we need Environmental & Natural Resource Accounts? National accounts widely used indicators to evaluate economic performance (GDP, NDP) statistics for economic planning What is wrong with National Accounts? – don’t account for: Depletion of natural capital—soils, fisheries, forests Environmental degradation (pollution affecting health) Many non-market goods not in GDP Non-market services provided by natural resources wrongly attributed to other sectors (value of water-soil protection by forests attributed to agriculture) omitted entirely (biodiversity protection, carbon storage)


Environmental & Natural Resource Accounts: Environmental & Natural Resource Accounts UN has compiled a Handbook, like the System of Integrated Environmental and Economic Accounts, or SEEA-2003 Specialized manuals available for water, fisheries and forestry Currently undergoing revision to bring (parts) up to the level of a ‘statistical standard,’ meaning all countries are expected to implement it, like the national accounts


What is the SEEA?: What is the SEEA? STOCK ACCOUNTS (Assets/wealth): Physical + economic value of stocks of natural resources, such as minerals, forests, fish, etc. FLOW ACCOUNTS (link to SAMs/IO): Material & energy use, pollution, environmental services, by economic sector Environmental protection and resource management expenditure accounts: resource user fees, subsidies, expenditures by govt to manage resources. Environmentally-adjusted macroeconomic indicators: GDP, NDP, Genuine Savings, Wealth

Slide8: Monitoring sustainable development: The Capital Approach to Sustainable Development What is the true economic contribution of forests? Water accounts: managing water scarcity


Natural Capital, National Wealth and Sustainable Development:  Contrasting Examples from Botswana & Namibia: Natural Capital, National Wealth and Sustainable Development: Contrasting Examples from Botswana & Namibia


Capital Approach to Sustainable Development: Capital Approach to Sustainable Development Shift in policy focus, from economic development as GNP/GDP growth to economic development as ‘portfolio management’ Total wealth = kProduced + kNatural + kHuman Key to Development in Resource-Rich Economies: transform natural capital into other forms of capital


Capital Approach to Sustainability: Capital Approach to Sustainability For production, which can be either consumed or invested, as a function of all forms of capital: Well-being, V, is defined as the discounted sum of all future utility, V = Σ U(c)/ (1+δ)τ-t Change in well-being is proportional to change in value of assets, ΔV= Uc · Σ pi ΔSi Where K= Σ Ki = Σ (pi ΔSi) for KP, KN,KH Sustainable development requires that Kt+1 ≥ Kt or Kt+1 / Pt+1 ≥ Kt / Pt , adjusting for population growth


Slide12: Transformation of Natural Capital requires policies to promote: economic efficiency in resource extraction to maximize resource rent INDICATOR: rent as % of Value-Added, GDP recovery of resource rent by an agency that will reinvest the revenues INDICATOR: % of rent recovered by taxes investment in alternative assets that that can replace natural capital VARIOUS INDICATORS: Botswana, % of rent used for govt capital budget


Contrasting Examples of Botswana and Namibia: Contrasting Examples of Botswana and Namibia High dependence on natural resources in both countries BUT, different resource mgmt. policies BOTSWANA: reinvestment of all mineral rent, indicator to monitor reinvestment (SBI) NAMIBIA: no explicit policy for mgmt. of resource rents


Methodology and Data: Methodology and Data K = KP + KN + KNetFor.Fin. (no est. of human capital) KP (Produced Capital): time series based on PIM for both countries KNFF (Net Foreign Financial Assets): Botswana: times series for 2 decades compiled by central bank Namibia: times series from 1990 (Independence) compiled by central bank


Methodology and Data: Methodology and Data KN (Natural Capital)—based on SEEA methodology Botswana: minerals (diamonds, copper/nickel, coal) Namibia: minerals (diamonds, uranium, gold) and fisheries (hake, horse mackerel, pilchards) Asset value = present discounted value of future rent Non-renewable resource: where pt = Rt/Qt (unit rent) and T=remaining lifespan of resource (Stock/Q) Rent, R, is Revenue - costs of production including normal profit 2. Renewable resource (fisheries): KN,t = ptQt/r (assumes sustainable management)


Calculating Resource Rent: Residual Value Approach: Calculating Resource Rent: Residual Value Approach For each type of mineral or fish, Resource Rent = TR – (IC + CE + CFC + NP) NP =  x K Where TR is Total revenue from sales of mineral/fish IC is Intermediate consumption for activity CE is Compensation of employees CFC is Consumption of fixed capital NP is “Normal profit”  is the opportunity cost of capital, 10-20% K is the value of fixed capital stock invested in the industry

Transformation Rule 1.Maximize Resource RentIndicator: Resource rent as share of industry value-added: Transformation Rule 1. Maximize Resource Rent Indicator: Resource rent as share of industry value-added Botswana Minerals: 75-84% of industry VA Namibia Minerals: 25-45% of industry VA Fisheries: 25-35% of industry VA


Transformation Rule 2. Resource Rent Recovery: Transformation Rule 2. Resource Rent Recovery Minerals, Botswana Minerals, Namibia Fisheries, Namibia


Transformation Rule 3. Reinvestment of Resource Rent: Transformation Rule 3. Reinvestment of Resource Rent NAMIBIA: NO REINVESTMENT POLICY! BOTSWANA: Explicit reinvestment policy: SBI = non-investment expenditures/non-mineral revenues. SBI < 1, fiscal sustainability Sustainable Budget Index of Botswana, 1980-2001


The SBI is simple—is it useful?: The SBI is simple—is it useful? Limitations: Overstates investment: health and education expenditures not all investment Applied on annual basis No assessment of value of govt investments funded by mineral revenues Not based on clear objective for optimizing “portfolio of assets” Designed for monitoring fiscal sustainability only, But fiscal sustainability depends on macroeconomic sustainability — Adjusted Net Savings/Total Wealth

Policy Uses of ANS/Total WealthMinistry of Finance, Botswana: Policy Uses of ANS/Total Wealth Ministry of Finance, Botswana Doesn’t want ‘bad news,’ but concerned about Moody’s bond rating Env. accounts address 2 of the 3 major areas of investor risk in Botswana Rising extraction cost/Depletion of diamonds Water scarcity HIV/AIDS Affect their cost of borrowing Green accounts Provide indicators for investors Provide govt with tools to monitor and manage these problems


Policy Use in other countries:Most have PRSPs, MDG programs : Policy Use in other countries: Most have PRSPs, MDG programs PRSPs, MDGs main objective: Sustainable economic growth with poverty reduction PSRP Monitoring matrix: Conventional macroeconomic indicators, e.g., GDP growth MDGs: no explicit target indicator for sustainable economic growth/development GDP measures economic growth, but does not take into account how much capital we are using up GDP measures economic growth ANS/Change in Total Wealth measures sustainability of growth BOTH ARE NEEDED!


Forest Accounts:Bringing Non-marketed Forest Goods and Ecosystem Services into the National Accounts: Forest Accounts: Bringing Non-marketed Forest Goods and Ecosystem Services into the National Accounts


How do countries use forest accounts?: How do countries use forest accounts? A. Total socio-economic value of forests What is total economic value of forests, including non-market values, and what are the benefits from sustainable forestry? What is the distribution of forest benefits among different groups in society, especially the poor? Is economic growth sustainable or based on depletion of resources, what is the cost of deforestation? B. Evaluate the impact of non-forestry policies and projects What are the trade-offs among competing users and how can forest use be optimized? What are the impacts of macroeconomic and non-forestry policies on forestry?

Future of Environmental & Natural Resource Accounting: Conditions necessary for widespread implementation : Future of Environmental & Natural Resource Accounting: Conditions necessary for widespread implementation


The success of national economic accounts: The success of national economic accounts The System of National Accounts was rapidly embraced in the second half of the 20th century because of a confluence of theory, methods to implement the theory and the needs of policy-makers. Policy challenge facing national economies: economic growth and full employment Theory to address this challenge: Keynesian macroeconomics Methodological framework--the information system needed to help address this challenge: System of National Accounts Environmental Accounting will also be embraced when such a confluence occurs.
