Study Notes

Environmental Management (EM) Overview

Key task of EM is to balance environmental capacity with developmental needs through sustainable practices based on scientific principles.
Units will cover a range of topics, including environmental policies, ecological principles, and assessment methodologies.

Unit Breakdown

Unit 1: Introduction to EM principles, tools, roles of participants, environmental ethics, and current concerns in India.
Unit 2: Focus on environmental policies, legislations, and international treaties.
Units 3 & 4: Environmental Impact Assessment (EIA) concepts and report preparation.
Unit 5: Methodology and processes of environmental auditing.
Unit 6: Introduction to Life Cycle Assessment (LCA) in EM.
Unit 7: Discussion of various EM system standards.
Unit 8: Analysis of EM issues and techniques.
Units 9 & 10: Examination of environmental design and economics.
Unit 11 (Optional): Industrial Pollution Prevention Control (IPPC).
Emphasis on learning about environmental sustainability at the conclusion.

Environmental Impact Assessment (EIA)

EIA was initially seen as a barrier to development but recognized for improving project quality and value over time.
The World Bank created an environmental section in 1971 to incorporate environmental context in developmental planning.
Significant negative impacts of hydro-projects include water-borne diseases, habitat destruction, biodiversity loss, and water quality deterioration.

Global Environmental Challenges

Handling hazardous waste emerged as a significant global issue in the 1980s.
Increasing chemical manufacturing in developing countries led to higher exposure to toxic substances for the populations.
Air pollution evolved from a local to a global issue, primarily caused by fossil fuel combustion, leading to severe consequences like acid rain.

Ozone Layer and Global Response

The 1985 discovery of a thinning ozone layer over Antarctica triggered international actions, leading to the 1987 Montreal Protocol to reduce CFC emissions.
The Helsinki Declaration of 1989 aimed for a complete phase-out of CFCs by 2000.

Climate Change Concerns

Increasing levels of CO2 and other greenhouse gases like nitrous oxide and methane have been acknowledged since the 1980s.
These gases contribute to the greenhouse effect, raising global temperatures.

Ecosystem Characteristics

Ecosystems consist of biotic (living) and abiotic (non-living) components interconnected in an orderly system.
Key characteristics of ecosystems include:
- Structure: Comprised of non-living parts (water, air, rocks) and living communities (interacting species).
- Processes: Include energy flow and chemical cycles within ecosystems.
- Succession: Ecosystems change over time, adapting and developing continuously.

Ecological Communities and Food Chains

Ecological communities are defined by the interacting species within a specific area, even if interactions are not well known.
Energy transfer in ecosystems occurs via food chains and food webs, illustrating how organisms obtain food and energy.
There are two primary types of food chains:
- Grazing Food Chain: Starts from green plants to herbivores and then to carnivores.
- Detritus Food Chain: Begins with non-living organic matter, moves to microorganisms, and continues to detritivores and their predators.

Energy Dynamics in Food Chains

Energy transfer efficiency is low; approximately 80-90% of potential energy may be lost as heat at each trophic level.
Shorter food chains allow for a higher energy availability to the population involved.
