NIGER DELTA ENVIRONMENTAL SURVEY
  • This paper is a highly condensed account of the
    Niger Delta Environmental Survey distilled from
    the 53-Volume Phase Two Report for a 25 minute
    presentation. Details of scientific methodology,
    findings and recommendations cannot possibly be
    set out in this short paper.

INTRODUCTION THE REGION
  • THE NIGER DELTA
  • a coastal region of global environmental and
    economic significance
  • one of the worlds largest wetlands
  • the worlds largest mangrove forest
  • Africas largest and the worlds third largest
    delta
  • West and Central Africas most extensive
    freshwater swamp forest
  • a mosaic of diverse and sensitive ecosystems that
    traverse four vegetation zones
  • Nigerias last remaining pristine rain forests
  • one of the continents few remaining habitats of
    unique biological species
  • one of the worlds major hydrocarbon provinces
  • (intense industry activities coexisting with
    sensitive ecosystems)

4
INTRODUCTION THE NIGER DELTA
  • CONSTRAINTS TO SUSTAINABILITY
  • rapidly deteriorating ecological and economic
    conditions
  • pervasive poverty
  • endemic instability over resource rights
  • social tensions not adequately addressed by
    existing policies and attitudes
  • region characterised by its parlous state in the
    midst of abundant living and hydrocarbon
    resources
  • paucity and unreliability of data
  • consequent absence of credible basis for
    addressing problems
  • diverse and conflicting stakeholder views on
    problems and possible solutions
  • World Bank warned in 1995 of urgent need to
    protect life and health of people and ecosystems
    from further deterioration

5
NDES FORMATION AND INDEPENDENCE
  • Under these circumstances, SPDC initiated NDES in
    February, 1995,
  • for independent and reliable information
  • as basis for understanding and tackling the
    environmental and economic problems of the region
  • to achieve development that is environmentally
    sustainable and people-centred
  • OPTS embraced Survey in March, 1996 with limited
    contribution
  • Conceived and implemented as an independent,
    participatory, people-centred survey
  • Independent Steering Committee with balanced
    stakeholder representation

6
NDES STRUCTURE, SCOPE AND METHODOLOGY
  • NDES implemented in six sectors
  • Participatory Rural Appraisal/ Participatory
    Learning and Action PRA/PLA
  • Socio-economics
  • Human Health
  • Biological Environment and Resources
  • Hydrology/Hydrodynamics
  • Pollution
  • in order to address the major concerns of
    sustainable development in three broad areas of
    Human, Biological and Physical environments.
  • Information integrated in digital (GIS) database
    and mapping to provide the region with a dynamic
    analytical tool and sustainable
    management/decision support system.
  • Participatory methodology, hub of the survey.

7
NDES STRUCTURE, SCOPE AND METHODOLOGY
  • The focal strategy was to concentrate on
  • providing a reliable basis to address constraints
    to sustainability and improvement of quality of
    life
  • elucidation of interactions between human and
    biological environments
  • physical environmental changes expected to be
    evident on state of biological environment.
  • The surveys six sectors and their relationships
    as they converge into the Niger Delta Development
    Priorities and Action Plan is schematically
    represented in the next slide

    polluted sites and region-wide determination of
    groundwater vulnerability.

14
PHYSICAL ENVIRONMENTHYDROLOGY/HYDRODYNAMICS
STUDIES
  • Mostly desk study limited field work because of
    funding constraints.
  • Hydrological processes dominant driving
    mechanism of the regions ecological concerns and
    also resource/capital stock to be sustainably
    managed.
  • Need for full-fledged hydrological survey, last
    study 40 years old cannot be used as the basis of
    our understanding considering many upstream and
    downstream developments.

GEOGRAPHIC INFORMATION SYSTEM DATABASE AND MAPPING
  • Aims and Objectives
  • To map and analyze the land use and vegetation of
    the Niger Delta over time using the available
    analogue and digital data sources, digitize the
    results and develop a geographical information
    system for environmental monitoring and
    management.
  • In order to achieve this aim, the specific
    objectives of the project are to
  • compile and digitize the topographical map of the
    area to provide the base map
  • analyze, map and digitize land use and vegetation
    of the region over three time periods
  • carry out a land use change detection analysis
    between the three time periods
  • develop a geographical information system based
    on the data generated in the above three
    activities and other sources for environmental
    monitoring and resource management.
  • Specific tasks performed
  • Seamless digital conversion of the topographical
    basemap at scale of 150,000
  • Seamless landuse and vegetation mapping and
    change detection analysis of the 1960s, 1980s and
    1990s to generate change distribution and trend
    statistics .

SUMMARY OF SOME MAJOR PRODUCTS (RESULTS) OF THE
NIGER DELTA ENVIRONMENTAL SURVEY
  • NDES report embodied in 53 volumes. Four,
    representing a fair summary of and covering most
    of the core concerns of the survey are briefly
    described
  • Atlas of Environmental Change in the Niger Delta
    (Volume 1, NDES Report)
  • Assemblage of digital maps at a scale of 150,000
    with statistical and graphical illustrations.
  • Depicting landuse and vegetation patterns over
    three time periods (epochs)
  • Exhibiting quantum, nature and spatial pattern of
    environmental changes from 1950s to 1999.
  • By this, the Niger Delta now has a versatile tool
    and spatial decision support system.
  • A solid basis for continuous monitoring,
    evaluation, planning and management of
    sustainable development.

22
SUMMARY OF SOME MAJOR PRODUCTS (RESULTS) OF THE
NIGER DELTA ENVIRONMENTAL SURVEY
  • The significant achievements and findings of the
    mapping and environmental change detection
    project are as follows
  • Creation of a composite digital database which
    can serve for developing an environmental
    management information system (EMIS)
  • Knowledge of changes would assist re-orientation
    of development towards desired goal.
  • In carrying out the mapping exercise, this
    project has come up with a classification scheme
    for land use and vegetation which can be modified
    and upgraded as knowledge on the environment
    improves. Such a classification scheme is
    crucial for regional planning purposes so that
    data and information and experiences gained in
    one part of the Niger Delta can be easily
    transferred to other parts with similar problems
    and environmental attributes.
  • Specifically, the analysis done in this study has
    shown the significant impact of oil production
    activities on the landscape of the Niger Delta.
    Many land use categories that were not there in
    1960 increasingly gained prominence on the
    landscape over time e.g. dredged canals, flare
    sites, burrow pits, pipelines.
  • The significant environmental impact of oil
    production activities is also highlighted by the
    emergence on the landscape of such land use
    categories as, saltwater impacted forest,
    submerged mangrove, dredge spoil, and open bare
    surfaces.

23
SUMMARY OF SOME MAJOR PRODUCTS (RESULTS) OF THE
NIGER DELTA ENVIRONMENTAL SURVEY
  • Over time, the built-up area has increased many
    fold obviously with the rapid growth in the rate
    of urbanization. The increase in the built-up
    area has been achieved at the expense of arable
    cultivation, secondary forests, high forests,
    rubber plantations, and mangrove swamps. In
    other words, mangrove swamps have been drained,
    and rubber plantations, forests and secondary
    forests cleared to make way for buildings and
    other man-made structures.
  • Although, arable cultivation lost out to built-up
    areas in many areas, it made up for the loss by
    taking over land from high forest, mangrove
    swamps, freshwater swamps and marshlands,
    secondary forests and palm bush.
  • Another subtle evidence of land degradation in
    the Niger Delta is the increase in the extent of
    the land use category tagged beach/mudflat/riverbe
    d sand. This is evidence of a high rate of
    sedimentation in this wet environment arising
    probably from increased erosion of the land and
    river banks.

SUMMARY OF SOME MAJOR PRODUCTS (RESULTS) OF THE
NIGER DELTA ENVIRONMENTAL SURVEY
  • The Niger Delta Development Priorities and Action
    Plan (Volume 2, NDES Report)
  • Achieving sustainability through the
    participatory and holistic approach.
  • Past development initiatives for this region and
    the nation in general, have failed because they
    were top-down, fragmented and sectoral in their
    approach, instead of being bottom-up,
    participatory and integrated. Environmental
    degradation, economic decline, social and
    political instability in the Niger Delta are
    either a direct consequence of the failure of
    these previous development approaches or were
    aggravated by them. There is clearly an urgent
    need for a new policy thrust that is holistic,
    participatory and cross-sectoral, integrating the
    regions environmental and developmental
    imperatives into an implementable programme of
    actions hinged on social justice, transparency
    and public accountability, if sustainable
    development is to be achieved.

35
SUMMARY OF SOME MAJOR PRODUCTS (RESULTS) OF THE
NIGER DELTA ENVIRONMENTAL SURVEY
  • Meeting the challenges of the deltas
    heterogeneous ecozones
  • The focal strategy for the formulation of the
    development priorities, policies, programmes and
    projects in this management plan was predicated
    on the heterogeneous nature and peculiar
    characteristics of Niger Deltas ecological
    zones. Dissimilar environmental and
    socio-economic attributes present varied
    constraints, challenges and opportunities, which
    determine appropriate policy responses,
    development programmes and projects.
  • One critical and common challenge though, is the
    difficult terrain that characterises most of the
    Niger Delta and which has been a major constraint
    to economic activities even before oil became the
    dominant issue. This difficult terrain
    provided a ready but unacceptable alibi for the
    gross neglect by successive governments,
    particularly since independence, of the region,
    which for more than a quarter of a century has
    accounted for some 95 of Nigerias foreign
    exchange earnings. The key challenge now is to
    reverse the backwardness and instability of this
    economically strategic region by building the
    confidence of its peoples through transparent and
    sustained infrastructure development and
    socio-economic transformation.

36
SUMMARY OF SOME MAJOR PRODUCTS (RESULTS) OF THE
NIGER DELTA ENVIRONMENTAL SURVEY
  • Critical Issues of a New Policy Thrust
  • To rapidly redress the regions neglect, ensure
    sustainable development, assuage the trauma and
    widespread anger of its peoples and promote its
    return to stability, this three-year Action Plan
    has been drawn up to provide policies, programmes
    and projects that are designed for immediately
    confronting the following critical issues
  • Environmental Management
  • Poverty Alleviation
  • Infrastructure Development and
  • Social Justice and Conflict Resolution.

37
SUMMARY OF SOME MAJOR PRODUCTS (RESULTS) OF THE
NIGER DELTA ENVIRONMENTAL SURVEY
  • Volume 3 Atlas of Social Infrastructure in the
    Niger Delta
  • This is a compendium of digital maps derived from
    the NDES GIS database, depicting the spatial
    pattern of available social infrastructure
    against the background of land use and vegetation
    (terrain and ecozone) information for each Local
    Government Area.
  • This document provides a flexible opportunity and
    the potential for an easy appreciation,
    evaluation and analysis of the current status of
    social infrastructure at the State, Local
    Government Area and Ward levels, while also being
    a sound management support system. Particularly
    suitable for meeting the developmental challenges
    of the regions heterogenous ecozones as it
    integrates environmental and socio-economic
    attributes.

SUMMARY OF SOME MAJOR PRODUCTS (RESULTS) OF THE
NIGER DELTA ENVIRONMENTAL SURVEY
  • Summary Volume The Summary and Recommendations
    volume captures the essence of the entire
    53-volume NDES Phase Two Report in a
    well-illustrated and user-friendly style,
    highlighting and cross-referencing a selection of
    key findings and interrelationships, designed for
    a general, non-technical readership. This volume
    provides the scientific basis for the
    recommendations set out in the Niger Delta
    Development Priorities and Action Plan.
  • The first two of these four documents, designed
    for use in tandem, provides planners, developers
    and managers of the delta a crucial
    state-of-the-art tool for sustainable
    development.

42
CONCLUDING REFLECTIONS
  • As collaborating agencies on the Gulf of Guinea
    Large Marine Ecosystems Project, the United
    Nations Industrial Development Organisation
    (UNIDO), the United Nations Development Programme
    (UNDP) and the United States National Oceanic and
    Atmospheric Administration (NOAA) have jointly
    recognised the Niger Delta Environmental Survey
    as a model and generic prototype for all
    developing coastal economies in the world.
  • Following a technical assessment visit to NDES,
    Professor Michael Watts, a consultant to both the
    Ford and McArthur Foundations, made the following
    remarks
  • I was deeply impressed by the quality of the GIS
    platform, and the sorts of cartographic and other
    information that has been generated. It is a
    world class project, and there is probably no
    comparable project (in terms of depth and
    coverage) of any delta in the world. The demand
    for, and utility of, the data generated is
    extraordinary government, the NGO community, and
    the private sector obviously have pressing needs
    for the sorts of information you have generated.

43
CONCLUDING REFLECTIONS
  • It is imperative that this information be
    circulated both to reveal to government and
    funders the quality and significance of the data
    generated but also to place such a valuable
    resource in the hand of those, and it is a
    substantial community, who need it most as soon
    as possible.
  • The cream of Nigerias distinguished scholars,
    experts and peer reviewers described the NDES
    report as an excellent job, a comprehensive and
    reliable information base and decision support
    system that should form the basis of the current
    government development initiative in the Niger
    Delta.
  • Yet, nearly three years after survey completion,
    report preparation, several rounds of
    international and local reviews and report
    finalisation, NDES report has still not been
    published, ostensibly for lack of funds.

44
CONCLUDING REFLECTIONS
  • In the meantime, major developmental initiatives
    from government, industry, bilateral and
    multilateral agencies are proceeding, post-NDES,
    using the failed top-down, fragmented,
    contract-driven approach of the past that had
    left the region parlous, short-changed by benefit
    captors and socio-economically unstable.
  • The oil industry, especially The Shell Petroleum
    Development Company of Nigeria Limited that
    conceived and mid-wifed NDES, is on the threshold
    of missing a historic opportunity. It will be a
    tragedy if the credit and benefit of what is
    perhaps industrys most meaningful and enduring
    contribution to the sustainable development and
    enhancement of quality of life in Africas
    largest and most richly endowed delta is either
    lost in the dust of time or allowed to have its
    immense value degraded by long bureaucratic
    delays. We believe it should be speedily
    published for the benefit of all stakeholders,
    especially the managers of the region,
    development agencies and the very people of the
    Niger Delta, the improvement of whose quality of
    life is central to the Surveys Mission.
