I – Evolving Environmental Perceptions
Protection of Nature
Pollution
Environment and Development - 1972
Eco development - 1973
Development without destruction – 1974

Alternative patterns of development and lifestyles 1977-1978
Sustainable Development 1982- 1992

water ( Quality and Quantity )
II- Deteriorating Environment :
Air (quality / climate change )
Land (soil, vegetation cover, minerals , Biological Resources )
![Page 5: Egyptian Italian Year of Science & Technology Egyptian Academy of Scientific Research and Technology Library of Alexandria Mostafa K.Tolba January 10,](https://reader035.vdocument.in/reader035/viewer/2022070411/56649f575503460f94c7b66d/html5/thumbnails/5.jpg)
Examples of Deterioration:
Tripling water demand over the last half- century Underground water: withdrawals beyond the recharge
Emerging water shortages
Food Production : A third or more of topsoil lost
Annual rise in land productivity - averaging 2.1 percent 1950-1990 - dropped to 1 percent 1990 to 2002
Range Land and Oceanic Fisheries pushed to their limits –
Climate Change

Facing Environmental Deterioration:
Adopting Realistic Prices of Water
Water Shortages: South Africa – lifeline rates: each household fixed amount - for basic needs at low price - when water use exceeds this level- price escalates.
Metering Underground water use: Jordan: 285 cubic meters - water person year.
Harvesting limited rainfall
Increasing Water productivity.In India raised by average190 percent shifting to drip irrigation .

-Energy and Raw Material
-Cleaner Production:
- Tools to Asses and Avoid Environmental Deterioration
A- Environmental Economics
cost of action and cost of inaction – Stern Report

Strategic Environmental Assessment
Cumulative Environmental Assessment
Environmental Impact Assessment
C- Environmental Assessment

D- Ecological Footprint :
Accounting tool measures a population's demand on nature.
Footprint of a country=
A- Total area required to produce food, fibre and
timber nation consumes
B- Absorb its waste
C- Space for infrastructure.
![Page 11: Egyptian Italian Year of Science & Technology Egyptian Academy of Scientific Research and Technology Library of Alexandria Mostafa K.Tolba January 10,](https://reader035.vdocument.in/reader035/viewer/2022070411/56649f575503460f94c7b66d/html5/thumbnails/11.jpg)
The Ecological Footprint is measured in global hectares.
Global hectare 1 hectare of biologically productive space.
Biologically Productive Area:
land and sea area with significant photosynthetic activity and production of biomass.
Earth's biocapacity:
nature's ability to produce resources from its biologically productive area.

- In 2005 ESIs, the Earth’s biocapacity gives 1.8 global hectares per person. Same year consumption 2.2 global hectares per person. Overshoot started 1980.
- In 2005 ESIs, humanity’s Ecological Footprint exceeded global biocapacity by 0.4 global hectare per person, twenty- three per cent.
Where are we today?
Global overshoot began mid 1980s.
Nature’s capital spent faster than it is being regenerated.
Equity and Intergenerational Rights
