ThinkRankLand, Soil, Water, Natural Vegetation and Wildlife Resources
Land, soil, water, vegetation, and wildlife form connected life-support systems. Human activities can improve access and livelihoods but can also cause erosion, pollution, desertification, deforestation, and habitat loss. Conservation combines scientific management with local knowledge and responsible institutions.
Learning Objectives
- •Explain land and soil are limited
- •Explain water and vegetation connect
- •Explain conservation is planned
Key Concepts
Land and soil are limited
Land use reflects relief, soil, water, population, technology, and competing demands; soil forms slowly and can be degraded quickly.
Water and vegetation connect
Rainfall, rivers, groundwater, forests, and crops influence one another through the water cycle and nutrient cycles.
Conservation is planned
Contour ploughing, terrace farming, rainwater harvesting, afforestation, regulated grazing, and protected areas address different risks.
Terminology
Historical Insight
Contour farming
Ploughing across a slope slows runoff and reduces the removal of fertile soil.
Community forest protection
Local rules and participation can protect forests when responsibilities and benefits are fairly shared.
Quick Check
How does soil erosion occur?
Why is water conservation linked to land use?
Name two soil-conservation methods.
How to use this lesson
Read the overview first, then explain the main idea in your own words before checking the key concepts. Use the quick-check questions without looking at the answer.
