    Study Notes

    Environment and Environmental Science

    • The environment refers to everything that surrounds us, including living and non-living entities.
    • Environmental science focuses on human activity's impact on the environment, including long-term implications for living organisms.

    Issues in the Environment

    • Rapid population growth puts strain on natural resources and reduces the benefits of development, with the global population in 2024 exceeding 119 million.
    • Poverty heavily contributes to environmental degradation, as many rely on natural resources for basic needs.
    • Water shortages and contamination are a significant threat to agricultural production, domestic and industrial uses.
    • Depletion of non-renewable fossil fuels is a consequence of increased industrialization and a growing population's overuse.
    • Deforestation and its threat to biodiversity are alarming, leading to a loss of species and a reduction in biological variety.
    • Improper disposal of solid and hazardous waste poses a significant environmental threat.

    Forest Resources

    • Forests are ecosystems where trees, shrubs, vines, herbs, and animal life live together in interdependence.
    • The Philippines ranked 5th in the world for the largest increase in forest area between 2010 and 2015, according to the Food and Agriculture Organization.
    • Specific areas are designated as Wildlife Forest Reserves (WFRs), including the Andap, Bagangga, Malagos, and Mati WFRs.
    • Presidential Decree 705 (PD 705) revises the Forestry Reform Code of the Philippines, outlining requirements for classifying lands, including slopes, as alienable and disposable.

    Environmental Impact Assessment System (EIS)

    • The Environmental Impact Assessment System (EIS) aims to achieve harmony between humans and nature.
    • PD 1586 promotes a balance between socio-economic growth and environmental protection.
    • The EIS System categorizes projects based on potential environmental impacts, requiring an Environmental Impact Statement (EIS) for projects deemed highly risky or with significant negative environmental impacts.
    • The system includes thresholds for various project types, such as iron and steel mills, petroleum and petrochemical industries, smelting plants, reclamation projects, roads and bridges, and golf courses.
    • Projects deemed unlikely to cause significant adverse impacts on the environment fall under Category D and are not covered by the Philippine EIS system.
    • The EIS System requires the completion of an Environmental Impact Assessment (EIA) and the development of an EIS report for environmentally critical projects.

    Environmentally Critical Areas (ECAs)

    • Environmentally Critical Areas (ECAs) are designated under Proclamation 2146 based on specific criteria.
    • Areas classified as ECAs include national parks, watershed reserves, wildlife preserves, sanctuaries, areas set aside as potential tourist spots, Class 1 and 2 caves, habitats for endangered species, key biodiversity areas, and areas of unique historic, archaeological, geological, or scientific interests.

    Challenges and Issues of the EIS System

    • Overlapping and conflicting implementation strategies among interrelated agencies pose challenges for the effective implementation of the EIS System.
