LC Contribution to the Area Frame Analysis and
Next Steps
  • The Central Statistic Agency (CSA) of Ethiopia,
    in collaboration with the European Union (EU) and
    FAO, is carrying out an area frame survey study
    in the country to improve the quality and
    reliability and timeliness of agricultural
    statistics.
  • Detailed and accurate land cover information
    contributes at improving analysis result.
  • FAO methodology produces a land cover database
    capable not only to improve the area frame
    statistical analysis, but also to provide
    national institutions with a standardized,
    multi-purpose product useful for several
    environmental and agricultural purposes.

Present Task long awaited L/C product for
Ethiopia
  • Built on original commitment from UNFPA/DFID
    for New Satellite High Resolution Coverage of
    Ethiopia at 5m res.
  • Basis for the creation of what will become one of
    the largest and most detailed databases of
    Environmental Information in Africa through the
    initiation of a new land cover product initiated
    for pilot testing in Amhara and Oromia Regions
  • 40 of the country by end project in Nov 2009
  • 750 tiles circa
  • Production chain dev. in January

Why the need of dynamic land cover
information at the global level Changing
world, emerging issues and increasing
anthropogenic pressure onland ecosystems
  • Between 1960 and 2005 in the world
  • population almost x 2
  • world economy x 3,5
  • production of grains more than x 2
  • production of fuelwood x 2.5, of sawnwood x 3
  • In 2010
  • population over 7 billion increase gt 20 in 10
    years( mainly in
  • developing countries), as a consequence,
  • need to increase world food production by 1,8
    / year
  • intensification of agriculture /alternatives
  • an additional 90 million ha may be brought into
    agriculture
  • (deforestation 13 million ha / year)
  • Poverty 1.2 billion
  • Under nourished 800 million
  • Ethiopia has more than its share of problems
    related to the above issues.

5
Land Cover Information Relevance at the National
Level
  • Increasing concerns about
  • food security for growing population
  • environmental degradation including the loss of
    biodiversity
  • climate change accompanied by growing frequency
    of natural disasters
  • Poverty, food insecurity and environment
    degradation are interlinked
  • Baseline natural resource information
  • an important component for addressing
  • the issues and developing operational
  • solutions

6
Summary of relevance of Land Cover
  • Land cover is the most important element for
    description and study of the environment
  • The main resource controlling primary
    productivity for terrestrial ecosystems can be
    defined in terms of land (and its cover)
  • Land cover is the easiest detectable indicator of
    human interventions on the land
  • Land cover is a critical parameter for
    environmental databases
  • Land cover changes quickly over time

7
UNIQUE SOURCE OF BASIC ENVIRONMENTAL INFORMATION
Standardization process - Comparability-
Increasing efficiency Cost reduction - Easy to
update - Conform international standards
8
National Mapping of Ethiopia
  • Example of national mapping by object-based
    methodology and using SPOT 5, 10 meter resolution
  • Important contribution for the national map with
    an high level of detail
  • Important contribution for statistical AF
    analysis.
  • Important contribution for multipurpose further
    applications
  • Important contribution to fill the regional gap
  • Important national inter-Agencies/Institutions
    collaboration/interchanges (MoARD, EMA, INSA,
    CSA) together with the international community
    (FAO, EU, UNEP) UN donors

9
Land Cover - multi-purpose info for multi-user
  • Land cover information in support of
  • Assessing progress made towards conventions and
    treaties UNFCCC, UNCCD, UNCBD, RAMSAR
  • Quantifying and understanding how policy impacts
    the composition and configuration of the various
    land cover over time
  • Measuring agricultural, urban, forestry expansion
    and the concomitant loss of natural ecosystems
    and related services- land cover
    change/degradation - LADA
  • Prioritizing activities (e.g. reforestation) to
    address multi- objectives (e.g. biodiversity,
    P.E.S.)
  • Assessing the magnitudes and distributions of
    global carbon sources and sinks and the processes
    controlling their dynamics e.g. updating
    biomass assessment inc R.E.D.D
  • Holistic and integrated approach to the
    conservation and sustainable use of land
    resources taking into account their multiple
    roles and functions.

10
Why do we need standards...?
Area estimates 11 cover types, different global
datasets

Land Cover and LC Change applications
  • Planning (Land Use and Planning, Development
    Activities Planning, Land Degradation Assessment)
  • Education
  • Research (Activities within Research Institutions
    and Universities)
  • Water (Watershed Management, Conservation,)
  • Agriculture (Soil and Land Conservation, Crop
    Statistics Monitoring, Fire Monitoring/
    impacts)
  • Environment (Forestry Biomass REDD MRV
    Biodiversity, Wildlife, Sensitive Areas, etc.)
  • Monitoring (Food Security, Early Warning)
  • Health (Habit of vector borne diseases etc.)
  • Other Application
  • Change analysis for
  • Agricultural (expansion/reduction)
  • Natural Vegetation (expansion/reduction)
  • Urban (expansion/reduction)
  • Land degradation
  • Updating Biomass assessment
  • Support to REDD - MRV
  • Soil Carbon Gap

Change Assessment (LADA) Agric, Forestry and
Urban Change
13
Change Assessment Senegal (LADA) and potential
emulation in Ethiopia
  • Within the Land Degradation Assessment (LADA)
    framework, an analysis of land cover changes in
    Senegal was carried out. The analysis covered 60
    land cover classes present in the Senegal 2005
    Land Cover legend.
  • Particular attention was given to the most
    sensitive areas such as forest, agricultural land
    and urban areas, using images taken in two dates
    1990 and 2005.
  • The 1990's Landsat TM images have been compared
    with the 2005 Landsat ETM set, and whenever a
    change was detected, a polygon to delimitate the
    change was drown and labelled.

Land use Planning - LRIMS
19
Land use Planning - LRIMS
  • to support the planning and development of the
    agricultural sector and strengthen the
    conservation efforts, and sound-use of the land.
  • potential establishment of a Land Resources
    Information Management System (LRIMS) aimed at
    deriving agricultural-specific indicators through
    the analysis of the multi-disciplinary database
    information.
  • LRIMS could assist in conducting the assessment
    of land suitability and for modeling land
    responses to agricultural policies

20
LRIMS Modules
  • LUT module
  • Climate module
  • Water module
  • Soil module
  • Topography module
  • Vegetation/LC module
  • Crop module
  • Socio-Economic module
  • LES module
  • Reporting module

21
LRIMS Land Evaluation Suitability Module
  • Generates the Final Yield grid for a certain crop
    (Maximum Potential Yield - Total Yield
    Reduction). Hence suitability ratings are
    assigned for Final Yield classes, thus LES maps
    can be created for different crops.

The factors governing Land Evaluation Suitability
(soil, water quality, topography, LUT,
vegetation/LC, and socio-economic) are presented
in the form of constraints which affect a crop
yield through yield-reduction percentages, where
each factor (constraint) is studied individually
as a classified layer (grid) and its
yield-reduction percentage is determined for each
of its classes.

Time frame
  • Completion of two provinces by Nov 2009
    improved methodology for acreage estimation
  • Additional Donor Support Requirements
  • Completion of the rest of the country 60
    essential - additional 14 mths (additional 1200
    tiles circa total 2000).
  • Importantly a single data assessment can form the
    basis of a critical land cover change programme
    to assess inter alia land degradation et. al
    detail.- plus 14mths.
  • Once completed multiple additional benefits to
    support P,E.S. requirements e.g. REDD Carbon seq
    potential est. et al... plus 12mths approx
  • Very important at this stage to have the donor
    community support for the products completion and
    its specific application development
