Answer: Precautionary principle and public participation
EIA emphasizes precaution (acting despite uncertainty to prevent harm) and inclusive public consultation for transparent, sustainable decisions.
Answer: False
Environmental monitoring occurs before (baseline), during (construction), and after (operation) project implementation to ensure compliance and impact management.
Answer: Thermal power plant
Large infrastructure and industrial projects like thermal power plants have significant environmental impacts and require mandatory EC.
Answer: Ministry of Environment, Forest and Climate Change
EACs, constituted by MoEFCC, appraise projects and advise the regulatory authority on granting or rejecting environmental clearance.
Answer: Identifying key environmental issues and setting terms of reference for the EIA study
Scoping determines the scope and depth of the EIA, ensuring focus on significant impacts and efficient use of resources.
Answer: True
SEA integrates environmental considerations into higher-level decision-making, complementing project-level EIA for sustainable development.
Answer: Detailed financial projections of the project
EIA reports focus on environmental, social, and health impacts; financial analysis is part of project feasibility studies, not EIA.
Answer: Impact
Environmental Impact Assessment is a process to evaluate potential environmental effects of proposed projects before decisions are made.
Answer: True
Public consultation, including public hearings, allows affected communities to voice concerns and is required for most large projects under EIA rules.
Answer: Projects listed in the Schedule with specified thresholds
The EIA Notification 2006 lists 39+ project categories requiring EC based on scale, location, and potential environmental impact.
Answer: Organic matter content and microbial activity
Soil organic matter and microbial diversity indicate fertility, structure, nutrient cycling capacity, and overall ecosystem health.
Answer: True
Mulch (organic or inorganic material) covers soil surface, reducing evaporation, moderating temperature, and inhibiting weed germination.
Answer: Windbreaks or shelterbelts
Planting rows of trees or shrubs as windbreaks reduces wind speed at ground level, minimizing soil particle displacement by wind.
Answer: 1994
UNCCD was adopted in Paris in 1994 and entered into force in 1996, focusing on combating desertification and mitigating drought effects.
Answer: Improves soil structure and water retention
Organic manure enhances soil porosity, nutrient content, and water-holding capacity, promoting sustainable agriculture.
Answer: True
In arid areas, evaporation concentrates salts in the root zone; poor drainage prevents salt leaching, leading to soil salinization and reduced fertility.
Answer: Crop rotation
Crop rotation improves soil fertility, breaks pest cycles, and reduces erosion by alternating crops with different nutrient needs and root structures.
Answer: Desertification
Desertification is land degradation in drylands resulting from various factors including climate variability and unsustainable land use.
Answer: True
Terracing creates stepped levels on slopes, slowing water flow, reducing erosion, and retaining soil moisture for cultivation.
Answer: Deforestation and overgrazing
Removal of vegetation cover by deforestation and overgrazing exposes soil to wind and water, accelerating erosion and land degradation.
