  1. : Resources Environmental Systems
  2. Natural Capital • Natural resources of ecosystems • Refers to sources of resources & services derived from Nature, • Forests, minerals, deposits, fertile soil, fishing grounds (Naturally existing resources) • ALSO gives way to INCOME through Goods and services
  3. Natural Income • Monetary income derived from Natural Capital, • Goods and services — processed or manufactured — have value to human population, • Resources properly managed that yields income to human livelihood,
  4. Types of general services — Natural Income • Provisioning : food, water, fuel, fibre, bio- chemicals • Regulating: Climate, disease, water regulation/purification, pollination • Cultural: spiritual/religious, recreational, ecotourism, inspirational, educational, cultural heritage. • Supporting: soil formation, nutrient recycling, primary production.
  5. Natural Capital (Earths resource base) HUMAN MANAGEMENT TO SUSTAIN RESOURCE NATURAL INCOME Marketable GOODS Ecological services
  6. Renewable Natural Capital • Comprises living species and ecosystems. • Self producing and self maintaining and uses solar energy and photosynthesis to produce food and chemical energy.
  7. Replenishable Natural Capital • Consists of stocks for non-living resources, • Ego Atmosphere, fertile soils and ground water. Such resources are dependent on energy from Sun for renewal
  8. Non-renewable Natural Capital • Consists of subsoil assets such as Fossil Fuels: oil, Coal • Copper (mineral deposits), diamonds, graphite • Such resources are depleted as they are consumed by human population (exploitation) • Resource depletion
  9. Environment and its Intrinsic Value 'One impulse from a Vernal Wood may teach you more of man, Of moral evil and of good, Than all the sages can" -William Wordsworth • Is the value that the entity has in itself • Nature — conservation philosophy Natural beauty in forests — Intrinsic Value
  10. Examples: Environment Intrinsic Value National parks • Protected areas • Cultural values of forests
  11. Environment Intrinsic Value Gross National Product GNP = Gross Domestic Product GDP = Human Development Index • HDI = = Gender Empowerment Measure (GEM GEM is a measure of inequalities between men's and women's opportunities in a country. It combines inequalities in three areas: political participation and decision making, economic participation and decision making, and power over economic resources. One of 5 indicators in UNDP). HPI = Human Poverty Index GDI = Gender-related Development Index
  12. Concept of Sustainability • Environmental Sustainability: is meeting the needs of the present generation without compromising the ability of future generations to meet their needs
  13. Sustainable Development • Recyclable resources Change over time — reused, replacement, innovation, • Resources, reserves and supply: Dynamic interchange • Identified resources, Undiscovered resources
  14. UN view of sustainable Development • Keeping population densities below Carrying capacity of a region • Facilitating the renewal of renewable resources • Conserving and establishing priorities for the use of non-renewable resources • Keeping environmental impact below the level required to allow affected systems to recover and continue to evolve
  15. SOCIAL Bearable Sustainable Environmental Viable Equitable Economic
  16. Environmental Sustainability Index • ESI — Benchmarks Ability of nations to protect the environment over the next several decades ESI integrates 76 data sets: tracking natural resources, environ management efforts and the capacity of a society to improve its environmental sustainability — 21 indicators of environ sustainability. • Indicators allow comparison across a range of issues grouped into 5 broad categories.
  17. Indicator of Environmental Sustainability Environmental systems Reducing Environmental stresses Reducing human vulnerability to environmental stresses Societal and institutional capacity to respond to Environmental challenges Global stewardship.
  18. Development and Environmental Sustainability: EIA ECO-Friendly Social Justice & Equity EARTH's Resources Public FUTURITY Participation 4 Key strands of development schemes
  19. Changing attitudes to Sustainability and Economic growth To Secure renewed political commitment to Sustainable development To access progress towards internationally agreed goals on Sustainable development To address new and emerging challenges
  20. Sustainable Yield • SY is the rates of increase in natural capital that can be exploited without depleting the original resource base of its potential replenishment. • SY= ( total Biomass/energy at time t+l) — (total biomass/energy at time t) • t = time of original natural capital • t+l = time of original natural capital + Yield • S Y = ( total energy at time t+l) — (total energy at time t) • SY = (Annual Growth & recruitment) — (annual death & emigration)
  21. Sustainable Yield • Examples of SY • Forestry Fishing Ground water • Maximum SY : Largest amount of raw material that can be extracted with permanently depleting the stock. • Best worked plan of action: European Union's Comment Fisheries Policy (CEP)
