Explain the concept of sustainable land management.
Practices that allow for the use of land resources without degrading them for future generations.
What is the purpose of cover crops?
To protect and improve soil health by preventing erosion and adding organic matter.
Explain the concept of sustainable fishing techniques.
Methods that minimize bycatch, protect habitats, and allow fish populations to replenish.
What is the role of government regulations in preventing overfishing?
Setting catch limits, establishing marine reserves, and enforcing fishing laws to protect fish populations.
What is the impact of reduced biodiversity?
Loss of ecosystem services, increased vulnerability to environmental changes, and potential economic losses.
What is the impact of habitat destruction?
Loss of biodiversity, disruption of ecosystem functions, and increased risk of species extinction.
What is the impact of water pollution?
Harm to aquatic life, contamination of drinking water sources, and potential health risks for humans.
What is the impact of soil erosion?
Loss of fertile topsoil, reduced agricultural productivity, and increased sedimentation of waterways.
What is the impact of vegetation loss?
Increased soil erosion, reduced carbon sequestration, and loss of habitat for wildlife.
What is the impact of loss of productivity?
Reduced food security, economic losses for farmers, and increased poverty.
What is Overgrazing?
Too many livestock on too little land, exceeding the land's carrying capacity.
What is Desertification?
Fertile land turning into desert-like conditions.
What is Overfishing?
Removing fish faster than they can reproduce.
What is Soil Salinization?
Soil becoming too salty.
What is Slash and Burn agriculture?
Clearing land by cutting and burning vegetation.
What is Terrace Farming?
Creating flat areas on hillsides for farming.
What is Irrigation?
Supplying water to crops.
What is Pastoral Nomadism?
Raising livestock and moving with herds.
Define Carrying Capacity.
The maximum number of individuals an environment can support without significant negative impacts.
Define Conservation.
Protecting natural resources and the environment.
What are the causes and effects of overgrazing?
Causes: Too many livestock. Effects: Soil erosion, vegetation loss, water quality issues, reduced land productivity.
What are the causes and effects of desertification?
Causes: Climate change, overgrazing, poor land management, deforestation. Effects: Loss of productivity, increased poverty, social instability.
What are the causes and effects of overfishing?
Causes: Removing fish faster than they can reproduce. Effects: Reduced biodiversity, habitat destruction, economic losses.
What are the causes and effects of pesticide use?
Causes: Pest control in agriculture. Effects: Harm to wildlife, water pollution.
What are the causes and effects of soil salinization?
Causes: Irrigation with salty water, poor drainage. Effects: Reduced crop yields, loss of biodiversity.
What are the causes and effects of slash and burn agriculture?
Causes: Clearing land for agriculture. Effects: Carbon dioxide release, soil erosion, habitat loss.
What are the causes and effects of irrigation?
Causes: Supplying water to crops. Effects: Water shortages, groundwater depletion, soil salinization, water pollution.
What are the causes and effects of draining wetlands?
Causes: Increase farmland. Effects: Decreases biodiversity, disrupts ecosystems.
What are the causes and effects of changing diets?
Causes: More variety, new foods, different preparation methods. Effects: Shift in purpose from individual consumption to global, profit-driven economy.
What are the causes and effects of terrace farming?
Causes: Creating flat areas on hillsides for farming. Effects: Allows farming on steep slopes, reduces soil erosion, retains moisture.
