2LC 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.
3Present 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
4 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.
5Land 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
6Summary 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
7UNIQUE SOURCE OF BASIC ENVIRONMENTAL INFORMATION
Standardization process - Comparability-
Increasing efficiency Cost reduction - Easy to
update - Conform international standards
8National 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
9Land 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.
10Why do we need standards...?
Area estimates 11 cover types, different global
datasets
11Land 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
12Change Assessment (LADA) Agric, Forestry and
Urban Change
13Change 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.

18Land use Planning - LRIMS
19Land 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
20LRIMS Modules
21LRIMS 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.

28Time 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
