Environment Sector by Rafia Kamal for TLP

  1. 1. Lahore The Green City of Tomorrow
  2. 2. Environment – What is it? The physical (non-living) and biological (living) factors along with their chemical interactions that affect an organism.
  3. 3. Another (simpler) definition of environment Everything that makes up our surroundings and affects our ability to live on the earth, the air we breathe, the water that covers most of the earth's surface, the plants and animals around us, and much more.
  4. 4. How it all started! The fast pace of industrial and technological advancements was achieved at the expense of unplanned massive consumption of natural resources. Widespread land transformations and rapid urbanization had profound influence on ecosystems that resulted in deterioration of environment.
  5. 5. Rio de Janeiro Conference on Sustainable Environmental Development, 1987 Brundtland Report “…development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
  6. 6. Need of the day Adherence to environmental friendly principles and practices is an essential tool in preservation and conservation of urban developments.
  7. 7. Where we wish to be A Green City of Tomorrow A sustainable and environmental friendly city
  8. 8. Environmental Issues in Lahore • Unplanned Urbanization and Land use changes • Depletion of Renewable and non-renewable resources. • Air and Noise pollution. • Water pollution, water depletion, water management. • Land/Soil pollution. • Waste generation and waste management. • Reduction in urban green spaces and deforestation.
  9. 9. Sustainability The Solution to Environmental Issues • Urban planning and Land use • Resource Management • Clean Air • Energy conservation • Water conservation and management • Waste minimization and management • Green infrastructure • Environmental planing, policy and implementation
  10. 10. Focused areas Unplanned Urbanization &Land Use Changes Deforestation and soil erosion.(Reduced tree cover with imbalance rain cycle, floods, Greenhouse effect and global warming leading to Urban heat island effect). Agricultural activity.(Land evacuation for agricultural use, Land degradation due to use of toxic chemicals of pesticides and fertilization). Urbanization activity. (Construction of buildings, roads, housing schemes).
  11. 11. Focused areas Resource Management Environmental resources management aims to ensure that ecosystem services are protected and maintained for equitable use by future human generations. The goal of resource management is sustainable use or to slow down the rate of resource utilization
  12. 12. Focused areas Renewable Resources. Natural resources which can be replenish within few human generations e.g Solar, Wind, Water, Biomass. Non-renewable Resources. Natural resources which cannot be replenished within few human generations. e.g Fossil fuels( Coal, oil, gas) and minerals.
  13. 13. Focused areas Clean Air To improve ambient air quality, Pollutant Standard Index should be followed. Regulatory measures to be taken to reduce emissions from stationary and mobile sources. a. Industrial sector b. Community services c. Vehicular emissions
  14. 14. Focused areas Energy Conservation Promote energy efficient energy saving practices. Green building designs Green technologies Encourage projects on renewable energy sources. Solar Hydal Biomass
  15. 15. Focused areas Water conservation and management. • Ensure water quality to meet international standards. • Ensure potable water quality to meet WHO standards for drinking water. • Reduce per capita domestic water consumption. • Enhance water conservation and management technologies ( Green Irrigation practices) • Increase supply of water from non-conventional sources. Watershed management.(Reservoirs) Rain water harvesting.
  16. 16. Focused areas Land Pollution (Soil pollution). Industrial effluents. Effluents and toxic chemicals from the drains of industries are a cause of soil contamination by entering into the ground water, water channels, agricultural soil and neibhouring populated areas through percolation and run off Pesticides and fertilizers Use of highly toxic fertilizers and pesticides for eradication of insects, fungi and bacteria from the crops and the overuse of these chemicals, result in contamination and poisoning of soil
  17. 17. Focused areas Land Pollution (Soil pollution). Waste and garbage dumping sites Unplanned waste disposal system results in dumping sites in various parts of the city as well as outskirts and river banks of Lahore which is another cause of land degradation and deterioration
  18. 18. Focused areas Waste Management What is waste? European Union definition "an object the holder discards, intends to discard or is required to discard”. Basel convention definition: Wastes are substances or objects which are disposed or are intended to be disposed or are required to be disposed of by the provisions of national laws.
  19. 19. Waste Management Types of Waste • Municipal Waste (Residential, commercial, institutional, industrial, and municipal). • Hazardous Waste • Industrial Waste • Bio-medical Waste • Agricultural Waste • Universal Waste • Construction and Demolition Waste • Radioactive Waste • Mining Waste
  20. 20. Waste management includes everything from Generation Storage Collection Transfer Transportation Processing and recovery Ultimate disposal
  21. 21. Integrated waste management Reduce - Source reduction. Reducing the quantity and toxicity of waste Reuse - Reusing existing products or packaging Recycle - the waste of one can be a resource for other, e.g. composting
  22. 22. Integrated waste management Incineration - controlled burning of solid, liquid, or gaseous wastes. Reduces volume & generates ” waste to energy”. Landfill - Physical facility spread on acres used for disposal of residual solid wastes in the surface soils of the earth. Source of methane gas.
  23. 23. Green Infrastructure What it means? A sustainable bridge between natural and built environments • Support native species • Maintain natural ecological processes • Sustain air and water resources • Contribute to the health and quality of life for communities and people
  24. 24. Focused areas Green Infrastructure. • Parks. • Gardens. • Green streets. • Green neighborhood. • Green buildings.
  25. 25. Green Infrastructure – how it works • Better air quality – trees • Temperature reduction – trees • Water shed management Rain gardens Bioswales Rain water harvesting Artificial wet lands • Green building designs • Green roofs • Green walls
  26. 26. Blue print for future Plans Procedures Policy Governance
