Study Notes
Philippine Coastal Zone and Marine Ecosystem
- Coastal zones are defined entities of land and water influenced by both land and sea processes.
- They are critical for the management of natural resources and biodiversity.
Definition and Characteristics of Coastal Areas
- Coastal areas are bands of dry land and adjacent ocean space affected by terrestrial and oceanic processes.
- Geographic extent typically spans one kilometer from the shoreline (high tide) to 200 meters into the sea, encompassing mangrove swamps, estuarine rivers, and coral reefs.
- Functionally, they serve as interfaces where high rates of production, consumption, and exchange occur.
- Ecologically, coastal areas are noted for their dynamic biochemical activities but have limited capacity for sustained human use.
Marine Areas and Ecosystems
- Marine ecosystems are aquatic environments characterized by high salt concentrations, including the open ocean and various coastal ecosystems.
- These ecosystems possess diverse physical and biological characteristics that differentiate them from freshwater environments.
Coastal Governance
- Multiple government institutions are involved in the management of coastal and marine areas, leading to potential conflict and confusion over responsibilities.
- Some areas, such as the high seas, may lack any governing authority.
- Inshore regions can be governed by multiple jurisdictions, such as district, city, and provincial levels.
Coastal Resource System
- The coastal resource system underscores the interdependence between the terrestrial environment, marine environment, and human activities.
- Effective resource management must consider this interconnectedness to sustain ecological and economic benefits.
Importance of Coastal Areas
- Coral reefs, estuaries, mangroves, and seagrass beds are vital components of coastal zones, offering ecological benefits and supporting biodiversity.
- Coastal areas are essential for both environmental health and human livelihood, highlighting the need for sustainable management practices.
Coastal Zone and Marine Ecosystem Overview
- Coastal zones are areas where the land meets the ocean, influenced by biological and physical processes from both environments.
- They provide critical natural resources and require careful management to avoid overexploitation.
Definition of Coastal Areas
- Comprised of land, adjacent ocean spaces, and submerged land, coastal areas are affected by actions and processes on land and sea.
- Defined geographically to include areas up to one kilometer from the shoreline at high tide and extending to the 200-meter isobath limit.
- Common coastal features include mangroves, estuaries, sandy beaches, coral reefs, and seagrass beds.
Functional and Ecological Characteristics
- Functionally, coastal areas are interfaces for intensive production, consumption, and exchange processes between land and water.
- Ecologically, these areas show high biochemical activity but are limited in capacity for various human uses, influenced by terrestrial activities.
Marine Areas
- Marine ecosystems are characterized by high salt content and include open oceans, deep-sea environments, and coastal waters.
- Each marine environment possesses distinct physical and biological characteristics.
Coastal Governance
- Multiple governmental institutions oversee coastal and marine areas, leading to complexities in management due to overlapping jurisdictions.
- High seas often lack governmental oversight, resulting in areas without defined management authority.
Interdependence of Environments
- Acknowledges the connection between terrestrial environments, marine ecosystems, and human activities, illustrating their interdependence.
- Coastal resource management must consider these interactions to maintain ecological balance and resource sustainability.
Value of Coastal Areas
- Coastal ecosystems such as coral reefs, estuaries, mangroves, and seagrass beds contribute significantly to biodiversity, fisheries, and coastal protection.
