Title: ENVIRONMENTAL POLLUTION IN NIGERIA


1
ENVIRONMENTAL POLLUTION IN NIGERIA
2
BACKROUND
  • PRE- COLONIAL ERA
  • COLONIAL ERA
  • RECENT TRENDS
  • - Industrial Growth
  • - Population Explosion
  • - Expansion in oil exploration, exploitation
    and use
  • - Urbanization
  • - Changes in lifestyles and consumption
    pattern

3
TYPES OF POLLUTION
  • POLLUTION IS THE INTRODUCTION OF SUBSTANCES INTO
    THE ENVIRONMENT THAT ALTER ITS PHYSICAL, CHEMICAL
    AND BIOLOGICAL PROPERTIES IN SUCH A WAY THAT IS
    HARMFUL TO LIVING ORGANISMS. IN THIS
    CIRCUMSTANCE, THE SUBSTANCES ARE TERMED AS
    POLLUTANTS

4
SOURCES OF POLLUTION
  • SOURCES OF POLLUTION
  • - POINT SOURCE POLLUTION RESULTS FROM DEFINITE
    SOURCES THAT ARE IDENTIFIABLE
  • - NON-POINT POLLUTION SOURCES THESE ARE
    DIFFUSE SOURCES THAT ARE NOT IDENTIFIABLE SUCH AS
    RUN-OFFS
  • POLLUTION CAN EITHER BE AIR, WATER OR LAND
    POLLUTION

5
AIR POLLUTION
  • MAIN CAUSES INCLUDE
  • - GASEOUS DISCHARGES FROM INDUSTRIES
  • - INDISCRIMINATE AND OPEN BURNING OF WASTES
  • - BUSH BURNING
  • - GAS FLARING
  • - INDOOR COOKING
  • - EMMISSIONS FROM GENERATORS E.T.C
  • - MINING ACTIVITIES

6
Air Pollution contd
  • MAJOR AIR POLLUTANTS
  • - COx, NOx, Sox, Particulates, H2S, CFCs,HCFCs,
    Dioxins and Furans e.t.c.

7
WATER POLLUTION
  • COULD BE UNDERGROUND OR SURFACE WATER POLLUTION
  • MAIN CAUSES INCLUDE
  • - RAW OR PARTIALLY TEATED INDUSTRIAL EFFLUENT
    DISCHARGES
  • - MUNICIPAL SEWAGE
  • - AGRICULTURAL RUN-OFF (Pesticide Residues,
    Fertilizer etc)
  • - INDISCRIMINATE DUMPING OF WASTE
  • - ACID DEPOSITION
  • - LEACHATES FROM WASTE DUMPSITES, LANDFILLS
    AND COMTAMINATED LANDS
  • - SALINE INTRUSION
  • - INVASIVE WEEDS

8
WATER POLLUTION CONTD
  • MAIN WATER POLLUTANTS INCLUDE
  • - HEAVY METALS
  • - NITROGEN
  • - PHOSPHORUS
  • MAJOR CONCERNS
  • - OIL GREASE
  • - BOD, COD
  • - SUSPENDED SOLIDS
  • - PH
  • - HIGH TEMPERATURE

9
LAND POLLUTION
  • MAIN CAUSES
  • - INDISCRIMINATE DUMPING OF INDUSTRIAL,
    MUNICIPAL AND HAZARDOUS SOLID WASTE
  • - INDUSTRIAL EFFLUENT AND DOMESTIC SEWAGE
    DISCHARGES
  • - TAILINGS FROM MINING AND MINERAL PROCESSING
    INDUSTRY

10
THE NIGERIA INDUSTRY
  • INDUSTRIAL ACTIVITIES WHICH HAVE GROWN OVER THE
    YEARS HAVE BEEN IDENTIFIED AS THE MAIN
    CONTRIBUTOR TO ENVIRONMENTAL POLLUTION IN NIGERIA
  • KEY CONCERNS
  • MORE THAN 8O OF INDUSTRIES IN NIGERIA DISCHARGE
    LIQUID, SOLIDS AND GASEOUS WASTES DIRECTLY INTO
    THE ENVIRONMENT WITHOUT ADEQUATE TREATMENT THAT
    MEETS THE BASIC STANDARDS
  • WASTE TREATMENT FACILITIES ARE EITHER
    NON-EXISTENT OR ARE OLD AND OBSOLETE
  • INDUSTRIAL SOLID WASTE ARE DISPOSED OF IN
    ENVIRONMENTALLY INSECURE DUMPSITES MOST TIMES IN
    MIXED FORMS

11
KEY CONCERNS CONTD
  • SOME OF THE INDUSTRIES LACK THE WHEREWITHAL TO
    ENGAGE IN SOUND ENVIRONMENTAL PRACTICES
  • COLLOSAL FINANCIAL LOSS RESULTING FROM POOR
    POLLUTION MANAGEMENT BY INDUSTRIES
  • THE HIGH POLLUTING NATURE OF THE NIGERIAN
    INDUSTRY MAKES THEM UNATTRACTIVE TO FOREIGN
    INVESTORS
  • Making Environmental Pollution Management A
    Wealth-Generating Venture

12
NIGERIAN INDUSTRIAL SECTORS AND THEIR IMPACTS
  • IRON AND STEEL
  • Water - Suspended Solids, Ammonia, Cyanides,
    Phenols, Heavy metals and organic pollutants, oil
    and grease, phosphates, chlorides etc
  • Air - Particulate matter, SOX, Fume and
    Alkaline oxide emissions, Iron oxide, Acidic,
    salt flux and solvent fumes
  • Main solid wastes steel scrap, scarfing
    residues, refractory materials etc

13
Industrial Sectors Contd
  • TEXTILES
  • Wastewater Dyes, Surfactants, oxidizing and
    bleaching agents, reducing agents, silicates,
    inorganic salts, oils, greases, waxes, chromium,
    zinc, lead, copper etc
  • Solid waste Fabric and fiber solid waste
  • Air Fibers, dust and volatile synthetic fibers

14
Industrial Sectors Contd
  • FOOD AND BEVERAGES
  • Organic wastes leading to suspended solids, ph
    and BOD problems
  • TANNERIES
  • - Chromium, Suspended solids, Acids, Nitrogen
    compounds, sulphides, vegetable tannings, oil and
    grease

15
Industrial Sectors Contd
  • PETROLEUM PETROCHEMICALS
  • Air Pollutants Carbon monoxide, particulates,
    Nitrogen oxides, organic acids, sulphur oxides,
    hydrocarbons, ammonia, aldehydes
  • Water oil and grease, heavy metals (Chromium,
    nickel, cadmium, copper)

16
Industrial Sectors Contd
  • MINING FOR SOLID MINERALS
  • - PARTICULATES, MINE TAILINGS, SURFACE AND
    GROUND WATER POLLUTIO FROM HEAVY METALS

17
Industrial Sectors Contd
  • CEMENT
  • Air- Cement kiln dust, particulates

OUR FRAMEWORK FOR POLLUTION MGT.
  • Legal Framework
  • Nigerian Constitution
  • National Laws, Guidelines, Regulations, Edicts
    and Byelaws such as
  • - The National Policy on Environment
  • - Act 42 of 1988 which makes it a criminal
    offence to import or trade in toxic wastes
  • - Regulations S. I. 8 and S. I. 9, which are
    the National Environmental Effluent Regulations
    and Pollution Abatement in Industries and
    Facilities Generating Waste Regulations.

22
Legal Framework Contd
  • - National Guidelines and Standards for
    Environmental Pollution Control in Nigeria
  • - Regulation S. I. 15, 1991, is for the
    Management of Solid and Hazardous Wastes
  • - Environmental Impact Assessment (EIA) Decree
    86, 1992 with its sectoral guidelines for
    Agricultural and Rural Development Oil and Gas
    Manufacturing Mining, Beneficiation and
    Metallurgical Processes and Infrastructures

23
  • Institutional Framework
  • Federal Ministry of Environment and its
    parastatal (i.e National Oil Spill Detection and
    Response Agency)
  • DPR
  • State Ministries Responsible for Environment and
    Parastatals
  • State Environmental Protection Agencies and
    similar institutions

24
  • Funding Framework
  • National, State and Local Government Budgetary
    Provisions
  • Ecological Fund
  • Multilateral and Bilateral Funding Assistance,
    World Bank Grants and Loans

25
SOME KEY CONSTRAINTS
  • INSTITUTIONAL CONSTRAINTS
  • ENFORCEMENT AND MONITORING
  • REGULATORY
  • CAPACITY (FINANCIAL, PERSONNEL TECHNICAL)
  • INFORMATION
  • INDUSTRIAL AND ECONOMIC POLICY (eg taxes and
    subsidies, interest exchange rates and
    commodity and waste pricing policies)

26
FUTURE TRENDS
  • Stronger Linkages between the following
  • Environment and Trade
  • Environment and Energy
  • Environment and Agriculture
  • Urbanization and Environment
  • Environment, Poverty Alleviation and Gender

27
FUTURE TRENDS CONTD
  • Other areas in which environment will be given
    considerable attention in future include
  • Tradable Commodities Environment is likely to
    emerge as a tradable commodity e.g. Emission
    trading.
  • Stock Exchange Waste Stock Exchange where the
    waste of one process serves as the raw material
    for another may be created.
  • Concession Environmental investments may become
    concession issues.
  • Waste to Wealth

28
CHALLENGES
  • MAIN CHALLENGE IS TO PROVIDE APPROPRIATE
    ADMINISTRATIVE AND EFFECTIVE INSTITUTIONAL, LEGAL
    AND FUNDING ARRANGEMENTS THAT WILL MATCH THE
    EMERGING TRENDS
  • GUIDING PRINCIPLE SHOULD BE GOOD ENVIRONMENTAL
    GOVERNANCE AND SUSTAINABLE DEVELOPMENT

29
CHALLENGES
  • Under-pinning economic development in accordance
    with the principles of sustainable development
  • Halting and reducing environmental degradation

30
CHALLENGES
  • Creating mechanism for Evaluating Environmental
    Performance including Strategic Environmental
    Assessment
  • - State of National Environment Report
  • - Developing Verifiable Performance
    indicators
  • - Creating compliance/Monitoring
    Evaluation Mechanism

31
THANK YOU FOR YOUR ATTENTION
32
  • Delineation of environmental responsibilities and
    liabilities between and among nations.
  • Development of an appropriate and effective
    Environmental Management Institutions which will
    be able to implement and mainstream environment
    into socio-economic development agenda in a
    better cross-linked manner than at present.

33
  • Creating Mechanism to Sustain and Compensate
    Environment for goods and services it provides
  • Creating Mechanism to enable emergence of
    environment as a tradable commodity
  • Creating the enabling environment to encourage
    investment in environment protection and
    improvement activities.
