- What is meant by “Crop rotation” in this lesson?Agriculture
- Crop rotation changes crops over time to influence nutrients, pests, and soil conditions.
- What is meant by “Integrated pest management” in this lesson?Agriculture
- Integrated pest management combines monitoring and suitable control methods while evaluating impacts.
- What is meant by “Nutrient management” in this lesson?Agriculture
- Nutrient management matches nutrient additions to crop needs and loss risks.
- What is meant by “Irrigation management” in this lesson?Agriculture
- Irrigation management aims to supply useful water while limiting waste and environmental damage.
- What is meant by “Agroecosystem” in this lesson?Agriculture
- An agroecosystem is a managed agricultural system including crops, organisms, soils, and their interactions.
- What is meant by “Food-system assessment” in this lesson?Agriculture
- Food-system assessment considers production, transport, storage, waste, and nutritional service.
- What is meant by “Forest regeneration” in this lesson?Forests
- Regeneration replaces or renews tree populations through natural establishment or planting.
- What is meant by “Selective harvesting” in this lesson?Forests
- Selective harvesting removes chosen trees and has outcomes depending on intensity, methods, and context.
- What is meant by “Clear-cutting” in this lesson?Forests
- Clear-cutting removes most trees from an area and creates effects that vary with site and subsequent management.
- What is meant by “Disturbance regime” in this lesson?Forests
- A disturbance regime describes the pattern of events such as fire, storms, or pests over time.
- What is meant by “Carbon storage” in this lesson?Forests
- Forest carbon is stored in vegetation, dead material, and soils and changes with growth and disturbance.
- What is meant by “Multiple-use management” in this lesson?Forests
- Multiple-use management considers several forest benefits and the conflicts among them.
- What is meant by “Fish stock” in this lesson?Fisheries and water management
- A fish stock is a population or management unit assessed for a fishery.
- What is meant by “Recruitment” in this lesson?Fisheries and water management
- Recruitment adds individuals to a population stage or fishery category under a stated definition.
- What is meant by “Bycatch” in this lesson?Fisheries and water management
- Bycatch is incidental capture of organisms other than the intended target.
- What is meant by “Sustainable harvest” in this lesson?Fisheries and water management
- A sustainable harvest seeks to maintain populations and ecosystem functions under changing conditions.
- What is meant by “Environmental flow” in this lesson?Fisheries and water management
- Environmental flow describes water quantity, timing, and quality needed to support ecosystems and associated uses.
- What is meant by “Adaptive management” in this lesson?Fisheries and water management
- Adaptive management uses monitoring to revise actions as evidence and conditions change.
