Study Notes
Resource Conservation Overview
- Resources are anything that satisfies human needs, including land, water, and biotic resources.
- Conservation is essential to prevent resource exhaustion, ensure sustainability for future generations, and maintain a continuous supply.
Land Resources
- Benefits include agricultural land, underground water, minerals, and forests.
- Issues affecting land resources:
- Improper land use and farming practices
- Land degradation and erosion
- Deforestation impacts ecological balance and biodiversity
Land Resource Conservation Strategies
- Protect land to restore its natural state through land use policies.
- Implement strict measures against overgrazing.
- Encourage practices like contour ploughing and reforestation.
- Construct dams to manage water resources effectively.
Water Resources
- Vital for agriculture, industry, households, and environmental activities.
- Water is a renewable resource critical for life and ecosystems.
Threats to Water Resources
- Pollution and agricultural runoff diminish water quality.
- Habitat destruction impacts aquatic ecosystems.
- Hazardous waste, population growth, urbanization, and sewage contribute to water resource depletion.
Biotic Resources
- Derived from the biosphere, these include materials from living organisms and organic matter.
- Biotic resources face various threats, impacting biodiversity.
Levels of Biodiversity
- Genetic Diversity: Variability within a single species.
- Species Diversity: Richness and abundance of species in a community.
- Ecosystem Diversity: Variety of habitats and ecological processes.
Values of Biodiversity
- Consumptive Use Value: Direct benefits like food (80,000 edible plant species) and medicines (75% of the global population relies on plant-based medicines).
- Productive Use Value: Commercially valuable resources marketed for trade.
- Social Values: Cultural significance of biodiversity in customs and religion.
- Ethical Value: Preserving all forms of life and recognizing existence value of extinct species.
- Aesthetic Value: Beauty of biodiversity contributes to eco-tourism and mental well-being.
- Option Value: Future potential of biodiversity yet to be explored.
- Ecosystem Value: Non-consumptive benefits such as nutrient cycling and water purification.
Philippine Biodiversity
- High species diversity and endemism, with many species at risk of extinction.
- Endangered species face threats due to habitat loss and human activities.
- Factors causing wildlife loss include population pressure and resource exploitation.
Habitat Loss Causes
- Growing human population increases demand for resources.
- Conversion of forests to agricultural land reduces natural habitats.
